Description:FIELD
The present disclosure relates to a field of automobiles and more specifically to a chassis used in automobiles.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
Generally, a chassis, also known as a frame, is a structural component of a vehicle which supports the vehicle body and many other components. The chassis is a foundation structure for supporting a powertrain, a transmission unit and a steering system. The chassis is provided with a plurality of cross members. These cross members separate the chassis with a front half chassis and a rear half chassis integrally built with a side member. The longitudinal member is bent for maintaining an offset between the track width of the front half chassis and the rear half chassis.
Typical, the conventional chassis of body on frame vehicles have a longitudinally arranged powertrain configuration. Accordingly, the cross members are positioned to maintain the powertrain in a longitudinally arranged configuration. However, the transverse positioning of the powertrain is not possible in the conventional chassis, since the track width provided in the front half of the chassis is not enough to accommodate the powertrain in the transverse configuration.
Further, the chassis is provided with a sloped or a bent between the front half and the rear half of the chassis. The bent or sloped is provided to accommodate varying track width in the front half and the rear half of the chassis. However, due to the presence of the bent or sloped profile in the longitudinal member of the chassis, the bend region becomes the critical region of the chassis. Also, due to the positioning of the powertrain in the longitudinal configuration in the conventional chassis, there is no provision to provide or attach the cross member near to the proximity of the sloped or bent region. Therefore, during the direct impact or the frontal crash of the vehicle, the impact directly gets transmitted to the longitudinal member and causes the conventional chassis to bend near to the bent or sloped region. And thereby, it may results in major fatal to the driver or the co-passengers seated in the front row of the vehicle as well as significant damage to the powertrain of the vehicle.
Therefore, there is a need of a chassis for a vehicle that eliminates the aforementioned drawbacks.

Yet another object of the present disclosure is to provide a chassis for a vehicle which facilitates easy mounting of different assemblies on the chassis.
Still another object of the present disclosure is to provide a chassis for a vehicle which facilitates the mounting of a powertrain in a transverse configuration.
Other objects and advantages of the present disclosure will be more apparent from the following description, which is not intended to limit the scope of the present disclosure.
SUMMARY
The present disclosure envisages a chassis for a vehicle. The chassis comprises a first longitudinal member, a second longitudinal member and a crossbeam.
The first longitudinal member and the second longitudinal member are extending along the length of the vehicle. The crossbeam is spanning the first longitudinal member at a first shoulder location and the second longitudinal member at a second shoulder location. The first shoulder location and the second shoulder location form an arcuate connection between the crossbeam, the first longitudinal member and the second longitudinal member to thereby define a first arm and a second arm.
Further, the first arm extends from the first longitudinal member and a second arm extends from the second longitudinal member towards an operative front of the chassis. The first arm, the second arm, the first shoulder location, the second shoulder location and the crossbeam define a cup-shape space to mount a powertrain transversely thereon..
In an embodiment, the chassis includes a plurality of first mounting means and a plurality of second mounting means. The first mounting means being operatively mounted to the first arm and the second arm. The second mounting means being operatively mounted to the crossbeam respectively.
In another embodiment, the first longitudinal member and the second longitudinal member is configured with a concave curvature on an operative outer edge of the first longitudinal member and the second longitudinal member, respectively.
In another embodiment, the chassis comprise a bracket to transversely hold the powertrain thereon. The bracket is configured to be operatively mounted on the plurality of first mounting means and the plurality of second mounting means to transversely mount the powertrain thereon.
Yet, in another embodiment, the chassis is provided with a plurality of cross members, configured to transversely connect the first longitudinal member and second longitudinal member.
Yet, in another embodiment, the first longitudinal member and the second longitudinal member are configured with a plurality of fixtures, and the fixture is configured to operatively mount the different assemblies on the chassis.
In an embodiment, the first longitudinal member and the second longitudinal member is selected from a group consisting a box shape cross section, a C-shaped channel cross-section, and a U-shape channel cross-section.
Yet, in another embodiment, the crossbeam and the cross member is selected from a group consisting an I-beam cross-section, a cylindrical tube cross-section, a C-shaped channel cross-section, and a U-shaped channel cross-section.
Since, the first shoulder location and the second shoulder location form an arcuate connection with the crossbeam, the first longitudinal member and the second longitudinal member; therefore during the frontal crash of the vehicle, the impact gets transmitted uniformly to the crossbeam in addition to the first longitudinal member and the second longitudinal member.
Also, the arms and the crossbeam collectively define the space with comparatively larger track width for mounting the powertrain thereon in the transverse configuration.
In an embodiment, the chassis refers to a chassis of an electric driven powered vehicle.
In another embodiment, the chassis refers to a chassis of a fuel driven powered vehicle, using gas as fuel or a hybrid type.

Typically, the conventional chassis 100’ of body on frame vehicles have a longitudinally arranged powertrain configuration. Accordingly, the cross members 16’ are positioned to maintain the powertrain in a longitudinally arranged configuration. The Figure 1A illustrates the conventional chassis 100’ provided with a powertrain 20 in a longitudinal configuration. However, the transverse positioning of the powertrain 20 is not possible in the conventional chassis 100’, since the track width provided in the front half of the chassis 100’ is not enough to accommodate the powertrain 20 in the transverse configuration. The Figure 1B illustrates the conventional chassis 100’ with the plurality of cross members 16’ attached along the longitudinal member of the conventional chassis 100’.
Further, the chassis 100’ is provided with a sloped or a bent between the front part and the rear part of the chassis. Therefore, during the direct impact or the frontal crash of the vehicle, the impact directly gets transmitted to the longitudinal members 16’ and causes the conventional chassis 100’ to bend near to the bent or sloped region. And thereby, it may results in major fatal to the driver or the co-passengers seated in the front row of the vehicle as well as significant damage to the powertrain 20 of the vehicle.
To overcome the aforementioned drawbacks, the present disclosure envisages a chassis 100 for a vehicle. The chassis 100 comprises a first longitudinal member 10, a second longitudinal member 12 and a crossbeam 14. The Figure 2 illustrates the chassis 100 provided with the first longitudinal member 10, the second longitudinal member 12 and the crossbeam 14 as per an embodiment of the present disclosure.
The first longitudinal member 10 and the second longitudinal member 12 are provided in a horizontal plane and are extending along the length of the vehicle. The crossbeam 14 is defined by a box type shape and configured to separate the first longitudinal member 10 and the second longitudinal member 12 in the horizontal plane. The crossbeam 14 is spanning the first longitudinal member 10 and the second longitudinal member 12. The crossbeam 14 abuts the first longitudinal member 10 at a first shoulder location 14a and the second longitudinal member 12 at a second shoulder location 14b, wherein the first shoulder location 14a and the second shoulder location 14b are the two opposite extremities of the crossbeam 14. The crossbeam 14 forms an arcuate connection with the longitudinal members.
In an embodiment, the first shoulder location 14a and the second shoulder location 14b form an arcuate connection between the crossbeam 14, the first longitudinal member 10 and the second longitudinal member 12.
Further, a first arm 22 and a second arm 24 extends from the first longitudinal member 10 and the second longitudinal member 12 from the respective shoulder locations towards an operative front of the chassis 100. The first arm 22 extends from the first shoulder location 14a and the second arm 24 extends from the second shoulder location 14b respectively. The arms 22, 24 and the crossbeam 14 defining a cup-shape space 26 for mounting a powertrain 20 transversely thereon. Figure 3 illustrates the cup-shaped 26 of the front part of the chassis 100 as per an embodiment of the present disclosure
In an embodiment, the first arm 22, the second arm 24, the first shoulder location 14a, the second shoulder location 14b and the crossbeam 14 generates the cup-shape space 26 within the front part of the chassis 100.
Advantageously, the cup-shape space 26 allows the distribution of stress uniformly along each member in connection. Therefore, during the direct impact or the frontal crash of the vehicle, the impact will get transmitted to the crossbeam 14 in addition to the first longitudinal member 10 and the second longitudinal member 12 and thereby absorbs the large amount of shock or impact and avoids the bending of the front part of the chassis 100.
Further, a plurality of first mounting means 28 and a plurality of second mounting means are configured on the front portion of the chassis 100. The first mounting means 28 is operatively mounted on to the first arm 22 and the second arm 24 respectively. The second mounting means 30 is operatively mounted on the crossbeam 14. Also, the chassis is configured with a bracket 34. The bracket 34 is configured to be operatively mounted on the plurality of first mounting means 28 and the plurality of second mounting means 30 to transversely mount the powertrain thereon. The powertrain is transversely mounted on the bracket 34 by means of plurality of screws or bolt or fasteners.
In an embodiment, the first mounting means 28 is mounted on to the first arm 22 and the second arm 24 by means of a plurality of fasteners selected from a group consisting of a screw, or a bolt.
In another embodiment, the second mounting means 30 is mounted on the crossbeam 14 by means of a plurality of fasteners selected from a group consisting of a screw, or a bolt.
In another embodiment, the bracket 34 is mounted on the first mounting means 28 and the second mounting means 30 by means of a plurality of fasteners selected from a group consisting of a screw, or a bolt.
Advantageously, the first mounting means 28 and the second mounting means 30 provided on the front part of the chassis 100 acts as restrictors for the powertrain, thereby the mounting means oppose the movement of the powertrain towards the rear side in the event of frontal crash or direct collision. Thus, it minimizes the possibility of intrusion of the powertrain in to the dash or passenger compartment of the vehicle.
Further, the first longitudinal member 10 and the second longitudinal member 12 are configured with a sloped profile proximal to the first shoulder location 14a and the second shoulder location 14b, respectively. The sloped profile at the first shoulder location 14a and the second shoulder location 14b forms a concave curvature 30 on an operative outer edge of the first longitudinal member 10 and the second longitudinal member 12, respectively. The crossbeam 14 abuts proximal to the sloped profile of the first longitudinal member 10 and the second longitudinal member 12. Figure 4 illustrates the chassis 100 provided with the crossbeam 14 attached at respective shoulder location 14a, 14b as per an embodiment of the present disclosure. Figure 5 illustrates the chassis 100 mounted with the bracket 34, the first mounting means 28 and the second mounting means 30. Figure 6 illustrates a mounting arrangement of the chassis 100 with the bracket 34, the first mounting means 28 and the second mounting means 30.
Advantageously, the crossbeam 14 configured near to the first longitudinal member 10 and the second longitudinal member 12 avoids the bending of the first arm 20 and the second arm 22 during frontal crash or direct impact and thus avoids major fatal to the driver or the co-passengers seated in the front row of the vehicle as well as avoid any damage to the powertrain 20 of the vehicle.
Also, since the first arm 20, the second arm 22 and the crossbeam 14 collectively form the cup-shape space 26 within the front part of the chassis 100, thereby it enables the mounting of the powertrain 20 in a transverse configuration.
In an embodiment, the first longitudinal member 10, the second longitudinal member 12 and the crossbeam 14 are integrally cast to form the chassis 100.
Further, the chassis 100 is provided with a plurality of cross members 16. The cross members 16 are configured to transversely connect the first longitudinal member 10 and the second longitudinal member 12. The transverse connection of the plurality of the cross members 16 provide robust structure to the chassis 100 as well as helps in uniform distribution of load. Also, the first longitudinal member 10 and the second longitudinal member 12 are configured with a plurality of fixtures 18. The fixtures 18 are configured to operatively mount the different assemblies on the chassis 100.
In one embodiment, the chassis 100 is shaped as a “ladder”.
In another embodiment, the first longitudinal member 10 and the second longitudinal member 12 are selected from a group consisting of a box shape cross section, a C-shaped channel cross-section, and a U-shape channel cross-section.
In another embodiment, the crossbeam 14 and the cross member 16 are selected from a group consisting an I-beam cross-section, a cylindrical tube cross-section, a C-shaped channel cross-section, and a U-shaped channel cross-section.
Advantageously, the first shoulder location 14a and the second shoulder location 14b form an arcuate connection with the crossbeam 14, the first longitudinal member 10 and the second longitudinal member 12; therefore during the frontal crash of the vehicle, the impact gets transmitted uniformly to the crossbeam 14 in addition to the first longitudinal member 10 and the second longitudinal member 12.
In an embodiment, the arms 22, 24 and the crossbeam 14 collectively define the space with comparatively larger track width for mounting the powertrain 20 thereon in the transverse configuration.
In an embodiment, the chassis 100 refers to a chassis of an electric driven powered vehicle.
In another embodiment, the chassis 100 refers to a chassis of a fuel driven powered vehicle, using gas as fuel or a hybrid type.
