TECHNICAL FIELD
[001] This disclosure relates generally to a chassis, and more particularly to a creating a bend in a chassis of a vehicle using one or more kink components.
BACKGROUND
[002] Usage of ladder chassis in vehicles is well known. The ladder chassis may include two side members running along a longitudinal direction. The ladder chassis may further include multiple cross members positioned between the side members so as to provide strength at regions where stress concentrations are high. The side members may include three parts - a front part, a rear part, and a bend part (also called a kink). The bend part is included in the structure of the ladder chassis in order to accommodate installation of wheel assembly and movement of wheels during steering and turning of the vehicle.
[003] In some conventional techniques, the kink is created by bending (for example, using a press bending machine) the side members. However, these techniques require long lengths of material, which is a challenge. Further, these techniques rely on setting up press shops and bending machines for performing bending operations, which adds to the cost of manufacturing. Moreover, the kink created by bending the side members develops unwanted stress concentrations around the bent areas, making the chassis prone to failure at high load cycles.
[004] Some other conventional techniques provide for welding together different components of the ladder chassis in order to create the bend part. However, welding deforms grain structure and induces built-up residual stresses in the components being joined together, thereby reducing strength of these components and of the overall chassis.
[005] Therefore, a mechanism is desired for creating a bend in a chassis of a vehicle, while overcoming the above problems.
SUMMARY
[006] In one embodiment, a chassis is disclosed. The chassis may include a front part having a left front side member and a right front side member. The left front side member and the right front side member are separated by a first lateral

width. The chassis may further include a rear part having a left rear side member and a right rear side member. The left rear side member and the right rear side member are separated by a second lateral width. It may be noted that the second lateral width may be greater than the first lateral width. The chassis may further include a left kink component having a front portion and a rear portion. The left kink component may be configured to be coupled to the left front side member via the front portion, and to the left rear side member via the rear portion. The left kink component may be configured to be a bend segment between the left front side member and the left rear side member. The chassis may further include a right kink component having a front portion and a rear portion. The right kink component may be configured to be coupled to the right front side member via the front portion and to the right rear side member via the rear portion. The right kink component may be configured to be a bend segment between the right front side member and the right rear side member.
[007] In another embodiment, a kink component for creating a bend in a chassis is disclosed. The kink component may include a middle portion having shape of a rectangular tub. The kink component may further include a front portion. A plane of the front portion may be inclined at a first angle with respect to a plane of the middle portion. The front portion may be configured to be coupled to a front side member of a front part of the chassis. The kink component may further include a rear portion. A plane of the rear portion may be inclined at a second angle with respect to the plane of the middle portion. The rear portion may be configured to be coupled to a rear side member of a rear part of the chassis. A value of the first angle and the second angle may be based on the difference between lateral width of the rear part and lateral width of the front part. The lateral width of the rear part may be greater than the lateral width of the front part. The kink component may be configured to be a bend segment between the front side member and the rear side member.
[008] In yet another embodiment, a vehicle is disclosed. The vehicle may include a front part of a chassis. The front part of the chassis may include a left front side member and a right front side member. The left front side member and the right front side member may be separated by a first lateral width. The vehicle may further include a rear part of the chassis having a left rear side member and a right rear side member. The left rear side member and the right rear side member may be separated by a second lateral width. The second lateral width may be greater than the first lateral width. The vehicle may further include a left kink component having a front portion and a rear portion. The left kink component may be configured to be coupled to the left front side member via the front portion and to the left rear side member via the rear portion. The left kink component may be configured to be a bend segment

between the left front side member and the left rear side member. The vehicle may further include a right kink component having a front portion and a rear portion. The right kink component may be configured to be coupled to the right front side member via the front portion and to the right rear side member via the rear portion.

DETAILED DESCRIPTION
[021] Exemplary embodiments are described with reference to the accompanying drawings. Wherever convenient, the same reference numbers are used throughout the drawings to refer to the same or like parts. While examples and features of disclosed principles are described herein, modifications, adaptations, and other implementations are possible without departing from the spirit and scope of the disclosed embodiments. It is intended that the following detailed description be considered as exemplary only, with the true scope and spirit being indicated by the following claims. Additional illustrative embodiments are listed below.
[022] Referring to FIG. 1A, a perspective view of a chassis 100 is illustrated in accordance with an embodiment of the present disclosure. In some embodiments, the chassis 100 may be implemented in a vehicle (not shown in FIG. 1), like a car, a trailer, etc. In some embodiments, the chassis 100 may include a front part 102 and a rear part 106. The front part 102 may include a left front side member 104A and a right front side member 104B. The left front side member 104A and the right front side member 104B may be separated by a first lateral width Wl. The rear part 106 may include a left rear side member 108A and a right rear side member 108B. The left rear side member 108A and the right rear side member 108B may be separated by a second lateral width W2. The front part 102 and the rear part 106 of the chassis 100 are further illustrated in detail in conjunction with FIG. 1B-1C.
[023] Referring now to FIG. IB, a perspective view of the front part 102 of the chassis 100 is illustrated in accordance with an embodiment of the present disclosure. As shown in FIG. IB, the front part 102 may include the left front side member 104A and the right front side member 104B. The left front side member 104A and the right front side member 104B may be separated by a first lateral width Wl. Each of the left front side member 104A and the right front side member 104B may have a C-shaped cross-section. As such, each of the left front side member 104A and the right front side member 104B may have a top flange, a web, and a bottom flange, such that the top flange and the bottom flange face each other. For example, as shown in FIG. IB, the right front side member 104B may include a top flange 118A, a web 118B, and a bottom flange 118C. The front part 102 may further include one or more cross members. For example, the front part 102 may further include a front cross member 112. The front cross member 112 may have a C-shaped cross section, and may include a top flange, a web, and a bottom flange (not shown in FIG. IB). It may be understood that these one or more cross members may provide strength to the front part 102 of the chassis 100.

[024] Referring to FIG. 1C, a perspective view of the rear part 106 of the chassis 100 is illustrated in accordance with an embodiment of the present disclosure. As shown in FIG. 1C, the rear part 106 may include the left rear side member 108A and the right rear side member 108B. The left rear side member 108A and the right rear side member 108B may be separated by the second lateral width W2. Each of the left rear side member 108A and the right rear side member 108B may have a C-shaped cross-section. As such, each of the left rear side member 108A and the right rear side member 108B may have a top flange, a web, and a bottom flange, such that the top flange and the bottom flange face each other. For example, the right rear side member 108B may include a top flange 120A, a web 120B, and a bottom flange 120C. The rear part 106 may further include one or more cross members, for example a rear cross member 114. The rear cross member 114 may have a C-shaped cross section, and may include a top flange, a web, and a bottom flange (not shown in FIG. 1C).
[025] It may be noted that the second lateral width W2 may be greater than the first lateral width Wl. In other words, the width of the chassis 100 may vary along the length of the chassis 100. As such, the chassis 100 should include a bend (also called a kink) between the front part 102 and the rear part 106 through which the width of the chassis 100 may decrease from the rear part 106 towards the front part 102. It may be further noted that this bend may be required in order to accommodate installation of the wheels (not shown in FIG. 1A) of the vehicle and to further accommodate the turning of the wheels during steering of the vehicle in left or right direction. The transition from the first lateral width Wl of the front part 102 to the second lateral width W2 of the rear part 106, i.e. the bend may be provided by one or more kink components. For example, a left kink component 110A and a right kink component HOB may couple the front part 102 and the rear part 106. It may be understood that due to the difference between the first lateral width Wl of the front part 102 and the second lateral width W2 of the rear part 106, a bend is created along the length of the chassis 100 via the left kink component 110A and the right kink component HOB. In other words, the left kink component 110A may be configured to be a bend segment between the left front side member 104A and the left rear side member 108A. In the same way, the right kink component HOB may act as a bend segment between the right front side member 104B and the right rear side member 108B. Further, the left kink component 110A and the right kink component HOB may act to bridge the gap between the front part 102 and the rear part 106 of the chassis 100. The left kink component 110A and the right kink component 110B are further explained in detail in conjunction with FIG. 2A-2E.

It may be noted that the left kink component 110A and the right kink component HOB (of FIG. 1) may have the same construction. By way of an example, in one orientation, the kink component 110 may act as the left kink component 110A, and in another orientation, may act as the right kink component HOB

[045] Further, as mentioned earlier, the second face 222 of the middle portion 206 of the kink component 110 may be configured to be coupled to the web of the rear cross member 114. The second face 222 of the middle portion 206 and the web of the rear cross member 114 may include equal number of holes, for example, six holes. As such, the second face 222 and the web of the rear cross member 114 may be coupled to each other using the sixth set of fasteners 116F passing through the holes in the second face 222 and the web of the rear cross member 114.
[046] In an embodiment, each of the above sets of fasteners, i.e. the first set of fasteners 116A, the second set of fasteners 116B, the third set of fasteners 116C,

the fourth set of fasteners 116D, the fifth set of fasteners 116E, and the sixth set of fasteners 116F may include a plurality of shear clips. For example, the plurality of share clips may be bolts, or nut-bolt assemblies. By way of an example, these bolts or nut-bolt assemblies may be made of medium carbon steel. In an alternate embodiment, each of the above sets of fasteners may include a plurality of rivets.
[047] It may be noted that during operation, the front side members 104 and the rear side members 108 may undergo various different loading conditions, such as twisting, rolling and parallelogramming. All these loading conditions may generate their corresponding stresses. For example, twisting occurs when one side member moves vertically with respect to the other side member. Rolling is the movement about the central axis of a frame, and parallelogramming is the movement of one of the side members fore or aft with respect to another side member. Due to these loading conditions, the corresponding stresses may be transferred between the front side members 104 and the rear side members 108 through the associated kink component 100. Further, a kink moment may be produced which may be transferred to the front cross member 112 and the rear cross member 114, and then to the front side members 104 and the rear side members 108. As such, these stresses which are transferred between the various components of the chassis pass through the above sets of fasteners. The above sets of fasteners are able to endure these various stresses, and thereby ensuring robustness of the chassis 100.
[048] Referring back to FIG. 2C, in an embodiment, a plane PI of the front portion 202 of the kink component 110 may be inclined at a first angle 9i with respect to a plane P2 of the middle portion 206 of the kink component 110. Further, a plane P3 of the rear portion 204 may be inclined at a second angle 02 with respect to the plane P2 of the middle portion 206. It may be noted that the first angle 9i and the second angle 02 may be based on the difference between the second lateral width W2 and the first lateral width Wl. For example, for a kink component having length (L), and the first angle 0i being same as the second angle 02, a relation between the first angle 0i or the second angle 02, the length (L), the first lateral width Wl, and the second lateral width W2 may be represented, as given below:
[W2 - Wj
sinQ., = sinQ^ =
1 " 2L
[049] As mentioned earlier, due to the difference between the first lateral width Wl and the second lateral width W2, a bend may be created along the length of the chassis 100 via the kink components 110. In particular, a first bend may be

created on the left side of the chassis 100 via the left kink component 110A, and a second bend may be created on the right side of the chassis 100 via the right kink component HOB. Each of the first bend or the right bend may be proportional to the sum of the first angle 9i and the second angle 02.
[050] By way of the front portion 202 being inclined at the first angle 9i with respect to the middle portion 206, and rear portion 204 being inclined at the second angle 02 with respect to the middle portion 206, the kink component 110 may create a bend in the chassis in the horizontal plane. In an embodiment, the front portion 202 and/or the front portion 202 may be additionally inclined with respect to the middle portion 206 in a vertical plane in order to create a bend in the vertical plane, for example, for accommodating a height requirement of the wheels of the vehicle.
[051] In an embodiment, the kink component 110 (i.e. the left kink component 110A and the right kink component HOB) may be manufactured by machining a material, for example, Aluminum or an Aluminum-based alloy like Aluminum 6061 alloy. For example, one or more machining process may be used for machining the material. As it will be appreciated by those skilled in the art, Aluminum-based material for the kink component 110 may help in making the chassis light-weight while providing sufficient strength and helping in making the vehicle more fuel efficient. These one or more machining processes may include Computer Numerical Control machining. Further, any other material may be used for manufacturing the kink component 110 as well.
[052] Referring now to FIG. 4, a perspective view of a section of a vehicle 400 is illustrated, in accordance with some embodiments of the present disclosure. The vehicle 400 may include the front part 102 of the chassis 100. The front part 102 of the chassis 100 may include the side members 104 viz. the left front side member 104A and the right front side member 104B. The left front side member 104A and the right front side member 104B may be separated by the first lateral width Wl. The vehicle 400 may further include the rear part 106 of the chassis 100. The rear part 106 of the chassis 100 may include the rear side members 108, viz. the left rear side member 108A and the right rear side member 108B. The left rear side member 108A and the right rear side member 108B may be separated by the second lateral width W2.
[053] The second lateral width W2 may be greater than the first lateral width Wl. In other words, the width of the chassis 100 may vary along the length of the chassis 100. As such, the chassis 100 may include a bend (also called a kink) between the front part 102 and the rear part 106 through which the width of the chassis 100 may decrease from the rear part 106 towards the front part 102. This may be so as to

accommodate the wheels of the vehicle, and to further accommodate the turning of the wheels during steering of the vehicle in left or right direction. The transition from the first lateral width Wl of the front part 102 to the second lateral width W2 of the rear part 106 may be provisioned by a left kink component 110A and a right kink component HOB. It may be understood that due to the difference between the first lateral width Wl of the front part 102 and the second lateral width W2 of the rear part 106, a bend is created along the length of the chassis 100 via the left kink component 110A and the right kink component HOB.
[054] As such, the vehicle 400 may further include one or more kink components 110. The kink components 110 may couple the front part 102 and the rear part 106 of the chassis 100 by coupling the front side members 104 and rear side members 108. For example, the vehicle 400 may further include the left kink component 110A. The left kink component 110A may include the front portion 202 and the rear portion 204. The left kink component 110A may be configured to be coupled to the left front side member 104A via the front portion 202 and to the left rear side member 108A via the rear portion 204. It may be noted that the left kink component 110A may be configured to act as a bend segment between the left front side member 104A and the left rear side member 108A. The vehicle may further include the right kink component HOB having the front portion 202 and the rear portion 204. The right kink component HOB may be configured to be coupled to the right front side member 104B via the front portion 202 and to the right rear side member 108B via the rear portion 204. Further, the right kink component 110B may be configured to act as a bend segment between the right front side member 104B and the right rear side member 108B.
[055] Therefore, the left kink component 110A and the right kink component 110B may allow for accommodating the wheels, viz. a left wheel 402A and a right wheel 402B of the vehicle 400, as shown in FIG. 4B. Further, the left kink component 110A and the right kink component HOB may allow for accommodating the turning of the left wheel 402A and right wheel 402B during steering of the vehicle 400 in left or right direction, as shown in FIG. 4C.
[056] Referring now to FIG. 5, a flowchart 500 of a method of assembling the chassis 100 is illustrated, in accordance with an embodiment. At step 502, the front part 102 of the chassis 100 and the rear part 106 of a chassis 100 may be assembled. For example, the front part 102 may be assembled from the left front side member 104A, the right front side member 104B, and one or more front cross members like the front cross member 112. Similarly, the rear part 106 may be

assembled from the left rear side member 108A, the right rear side member 108B, and one or more rear cross members like the rear cross member 114.
[057] At step 504, the left kink component 110A and the right kink component 11 OB may be manufactured. The left kink component 11OA and the right kink component HOB may be manufactured by machining a piece of Aluminum using one or more machining processes like Computer Numerical Control (CNC) machining. At step 506, one or more holes may be drilled in each of the front part 102 of the chassis 100 and the rear part 106 of the chassis 100. The left kink component 110A and the right kink component HOB may already include holes which may be formed during manufacturing.
[058] At step 508, the front part 102 and the rear part 106 of the chassis 100, the left kink component 110A, and the right kink component 110B may be aligned, so that the holes drilled in the front part 102 and the rear part 106 of the chassis 100 align with the holes of the left kink component 110A and the right kink component HOB. At step 510, fasteners may be tied via the holes in the front part 102 and the rear part 106, the left kink component 110A, and the right kink component HOB. By way of an example, the fasteners may be bolts, or nut-bolt assemblies, or rivets, etc. As a result, an assembled chassis 100 may be obtained.
[059] One or more techniques for creating a bend in a chassis using one or more kink components are described above. The above techniques provide various advantages over the conventional techniques. For example, by providing for assembling the chassis using different parts, the above techniques do away with the inconvenient and costly task of procuring and transporting long side members. Further, the above techniques eliminate the need of bending the side members to create the bend, and thereby avoid the expensive and large size bending machines like jigs and workbenches required for bending operations. Furthermore, the above techniques eliminate the chances of unwanted stresses developing in the chassis due to bending. Moreover, the above techniques provide for an easy process for manufacturing the chassis and the vehicle, by simply assembling various different components, using fasteners like bolts. If a component develops a fault, the techniques allow for disassembling the chassis and easily servicing or replacing the faulty components. By replacing or servicing the faulty components, additional costs involved in replacing the entire chassis are avoided. The Aluminum-based material of the components helps in making the chassis and vehicle light-weight yet strong, thereby improving fuel-efficiency.
