TITLE: “A CUTTING TOOL ASSEMBLY AND A SYSTEM FOR BEDDING A
BRAKE LINER OF A VEHICLE”
Name and Address of the Applicant: TATA MOTORS LIMITED, of Bombay House, 24 Homi Mody Street, Hutatma Chowk, Mumbai – 400 001, Maharashtra, India
Nationality: INDIAN
The following specification particularly describes the nature of the invention and the manner in which it is to be performed.

TECHNICAL FIELD
Present disclosure, in general, relates to a field of automobile engineering. Particularly, but not exclusively, the present disclosure relates to a cutting tool assembly and a system for bedding a brake liner of a vehicle.
BACKGROUND OF THE DISCLOSURE
Brakes consisting brakes liners are generally prepared by baking raw materials such as organic binders and various other materials followed by pressing the baked raw materials to form brake liners. During manufacturing of such brake liners, manufacturing defects would result in uneven profile of the brake liner. Hence, braking using newly manufactured brake liners would lead to improper braking or uneven break-in of the brake liner. Such new brake liners would have about 30% contact with a brake drum resulting in inefficient braking and may result in poor stopping of the vehicle leading to accidents during driving.
Conventionally, in order to break-in the new brake liners, brake bedding process is followed. Brake bedding is a process of turning one or more brake liners to achieve a desired uniform brake liner thickness thereby achieve higher percentage contact between a brake drum and the brake liner. Turning of the brake lines is also performed to achieve concentricity between an outer diameter of brake liner with the inner diameter of the brake drum. Brake bedding is carried out on a front and rear axle to improve the brake efficiency. In certain vehicles such as Commercial vehicles such newly employed brake liners are manually bedded in order to complete break-in. Further, for efficient braking, brake contact patten needs to be more than 85-95 %. As this is a manual process, brake bedding is carried out on high speed track and requires more human intervention and a tedious activity also takes too much effort and time. Therefore, manufacturers generally advice soft to mild braking instead of hard braking in order to break-in the brake liners at least for initial 500 to 1000kms.
Further, existing brake bedding methods include turning of the brake liners on lathes or manually turning the brake liner to achieve uniform thickness of the brake liners. Further, in order to achieve linear contact pattern of more than 85 %, vehicles may be driven on low traffic density road, special route or own high speed track to brake in the brake liners. Existing process is more time consuming, requires more fuel and manpower by considering process flow.

The present disclosure is directed to overcome one or more limitations stated above. The background section of the present disclosure should not be considered as a limitation of the present disclosure.

Fig. 1 illustrates a cutting tool assembly (100) for bedding of a brake liner (6) of a vehicle. For ease of illustration, embodiments of the present disclosure shall disclose a bedding of brake liner (6) for drum brakes of the vehicle. The brake liner (6) [best seen in Fig. 2] of a brake (5) may be defined with a width and a length such that the width of the brake (5) liner may correspond to a width of a wheel axel (110) of a vehicle, while the length of the brake liner (6) may define a section of a circumference of the wheel axel (110). The assembly includes a first wedge (12a) and a second wedge (12b) separated by a predefined length. The predefined distance between the first wedge (12a) and the second wedge (12b) may be equal to or greater than the width of the brake liner (6). Further, the first wedge (12a) and second wedge (12b) may be defining a cuboidal or trapezoidal cross-section and made of materials such as but not limited to steel, aluminum, polymers, composites, ceramics etc. The cutting tool assembly (100) may include guide rods (17) defining a length and positioned perpendicular to a length of the first wedge (12a) and a second wedge (12b). The first wedge (12a) and the second wedge (12b) may be configured to receive the plurality of guide rods (17) such that the plurality of guide rods (17) may pass through both the first and second wedges (12b). As an example and as shown in Fig. 1, considering two guide rods (17), the two guide rods (17) may be separated by a predefined length and pass through the first wedge (12a) and second wedge (12b). The

plurality of guide rods (17) may be rigidly coupled to the first wedge (12a) and second wedge (12b) without any relative movement between the plurality of guide rods (17) and the first wedge (12a) and the second wedge (12b).
Referring again to Fig.1, the cutting tool assembly (100) may include at least one threaded rod (18) receivable between the first wedge (12a) and the second wedge (12b). The threaded rod (18) may be positioned parallel to the guide rods (17). In an embodiment, at least one threaded rod (18) may be positioned in between two guide rods (17). Further, the at least one threaded rod (18) may pass through the first wedge (12a) and second wedge (12b) such that the threaded rod (18) is slidably coupled to the first wedge (12a) and the second wedge (12b). The threaded rod (18) may be defined with a timing gear (11) at one end of the at least one threaded rod (18) proximal to the first wedge (12a). Furthermore, the cutting tool assembly (100) may include a tool post (10) threadedly engaged with the at least one threaded rod (18). The tool post (10) may be defining a geometric cross section such but not limiting to a rectangle or a trapezium such that the plurality of guide rods (17) may pass through a thickness of the tool post (10). The tool post (10) may include a threaded hole having complementary threaded in comparison to the threaded rod (18) passing through the tool post (10). The tool post (10) may be configured to receive a cutting tool (15). rotation of the timing gear (11) may displace and rotate the at least one threaded rod (18), thereby displacing the tool post (10). Additionally, the cutting tool assembly (100) may include a plurality of connecting links (13) rigidly connectable to the plurality of guide rods (17) and positioned perpendicular to the guide rods (17). The connecting links (13) may be defined with holes (14a) at a free end of the connecting links (13). In an embodiment, the connecting links (13), the first wedge (12a), the second wedge (12b), the plurality of guide rods (17) and the threaded rod (18)s may be made of materials such as but not limiting to steels, aluminum, alloys, polymers, composites and ceramics etc.
Now referring to Fig. 2, rotation of the timing gear (11) in a clockwise direction may displace the tool post (10) in an X-direction along a width of the brake liner (6) as shown in Fig. 2. Rotation of the timing gear (11) in an anti-clockwise direction may displace the tool post (10) in the X’ direction. In an embodiment, one full rotation (360°) of the timing gear (11) may displace the tool post (10) by distance ranging between 2mm to 10 mm along the X direction or X’ direction. As per a user requirement, the displacement of the tool post (10) may be calibrated to displace as required. The calibration of displacement of the tool post (10) may be

performed by various methods such as varying the threading angle, pitch or module of the at least one threaded rod (18).
Now referring Fig. 3, the figure discloses a system (200) for bedding a brake liner (6) of a vehicle. The system (200) includes a gantry (24) defined with a pair of guide pillars (23) such that the guide pillars (23) may be separated by a predefined gap. A gantry (24) may be a structure having two pillars and an overhang connecting the two pillars. The gantry (24) may be positioned on a base plate (51) proximal to the ground. The gantry (24) may be positioned such that the pair of guide pillars (23) of the gantry (24) may be perpendicular to the ground and define a lower end (48a) and an upper end (48b) and separated by a height of the guide pillar. Further, the pair of guide pillars (23) may be connected by a parallel beam (26) positioned at the upper end (48b) of the guide pillars (23) connecting the pair of guide pillars (23). Furthermore, the system (200) may include a frame (35) movably connected to the pair of guide pillars (23). The system (200) also includes a motor (25) defined with a drive shaft (28) and connected to the frame. The drive shaft (28) of the motor (25) may be rotatably coupled to the wheel axel (110) of the vehicle. Additionally, The base plate (51) associated with the gantry (24) may be fitted with rollers (52) to assist portability
Referring again to Fig. 3, reference will now be made to the frame (35) and constructional dependencies of the frame (35) with other components of the system (200). The frame (35) maybe include a front plate (36) defining a central cavity (50) to accommodate the drive shaft (28) of the motor (25), Further, the front plate (36) may be coupled the guide pillars (23) via a slidable member. The slidable member, the motor (25) such that displacement of the motor (25) along the height of the guide pillar may displace the frame (35) coupled to the guide pillar via the slidable member. Further, the pair of guide pillars (23) may also include a first locking unit (45) engageable with the frame. The first locking unit (45) may be configured to restrict relative movement between the frame (35) and the guide pillars (23). As an example, consider that the guide pillars (23) are defined by sequential holes along the height of the guide pillar. The first locking unit (45), which may include a threaded portion connectable to a knob and may be inserted through the slidable member (37) into at least one of the sequential holes to restrict relative movement between the slidable member (37) and the pair of guide pillars (23). Furthermore, the frame (35) may include a beam (30) defining a first end (32a) and a second end (32a). The first end (32a) of the beam (30) may be connectable to the frame (35) while the second end (32a) of the beam (30) may include an actuation gear (31). The second end (32a)

of the beam (30) may be positioned proximal to the wheel axel (110). Additionally, the beam (30) includes a tube (32) slidable mounted within the beam (30) and coupled to the actuation gear (31). The tube (32) maybe displaceable along a length of the drive shaft (28). The beam (30) includes a second locking unit (46) engageable with the tube (32) such that the second locking unit (46) may be configured to restrict relative movement between the beam (30) and the tube (32).
Referring again to Fig. 3, the system (200) may include the cutting tool assembly (100) connectable to the wheel axel (110). The connecting links (13) of the cutting tool assembly (100) may be defined with a hole at free end of the connecting links (13). The plurality of connecting links (13) may be engageable with a complementary fastening member (14b) positioned on the wheel axel (110). Further, the system (200) includes a counter-weight (40) positioned radially opposite to the cutting tool assembly (100) and connectable t the wheel axel (110). The counter-weight (40) may be configured to impart balanced rotational inertia to the wheel axel (110) during rotation of the wheel axel (110). Furthermore, the system (200) includes a variable frequency drive (VFD) (47) connectable to the motor (25) and configured to step down a rotational speed of the motor (25). Additionally, the system (200) includes a winch connectable to the gantry (24) and disposed on the parallel beam (26). The winch may be connected to the frame (35) associated with the motor (25) and configured to displace the motor (25) in a direction parallel to the guide pillars (23). Actuation of the winch may displace the motor (25) and frame (35) between a first position (as seen in Fig. 4a) and a second position (as seen in Fig. 4b).
In an operational embodiment, cutting tool assembly (100) may be positioned such that the cutting tool (15) is placed towards one end of the brake liner (6) and in contact with the brake liner (6) at a predetermined depth to be machined. On driving the motor (25) by a power supply, the variable frequency drive may be configured to step down an AC power supply to rotate the drive shaft (28) of the motor (25). The drive shaft (28) rotatably coupled to the wheel axel (110) may rotate as the speed of the drive shaft (28). The rotating wheel results in rotation of the cutting tool assembly (100) along with the wheel axel (110). It is to noted that the brake liner (6) is stational during rotation of the wheel axel (110). The second locking unit (46) may be unlocked to allow movement of the tube (32) parallel to the drive shaft (28). The extension of the tube (32) associate with the actuation gear (31) may displace the actuation gear (31) proximal to the wheel axel (110). It is to be noted that the timing gear (11) associated with the

wheel axel (110) may describes a circle during rotation of the wheel shaft. The displacement of the actuation gear (31) proximal to the wheel axel (110) may rotate the timing gear (11) in a clockwise direction upon contact with the actuation gear (31). Such rotation of the timing gear (11) results in the displacement of the tool post (10) along the length of the width of the brake liner (6). Such displacement of the tool post (10) may result in the displacement of the cutting tool (15) along the length of the guide rods (17) resulting in material removal from the brake liner (6). Such material removal may be performed throughout the length and the width of the brake liner (6) thereby bedding the brake (5). In an embodiment, the counter weight (40) may be replaced with another cutting tool assembly (100), thereby achieve rotational balance as offered by the counter weight (40) as well as perform faster bedding of the brake liner (6).
In case of heavy duty vehicles, the wheel axel (110) of such vehicle may be larger than commercial vehicles. In such cases, the winch may be actuated to align the drive shaft (28) of the motor (25) to the wheel axel (110). Further, during material removal i.e., brake bedding or turning operation, chips of material may jump off from the brake liner (6), the front plate (36) associated with the frame (35) may assist in blocking hot chipped off material from reaching an operator positioned behind the motor (25), thereby ensuring safety of an operator operating the system (200). Further, the system (200) may also be used to perform in situ (in vehicle) brake bedding, thereby prevent additional tool requirement and transportation of the brake liner (6) towards a tool bed to perform brake bedding. Furthermore, flexibility of operation of the gantry (24) and the cutting tool assembly (100) allows for brake bedding of various type of brake liner (6) and vehicle.
The system (100) and the cutting tool assembly (100) of the present disclosure shows advantage of portability due to presence of rollers associated with the gantry (24) and due to size of the cutting tool assembly (100). Further, lower man power may be required to operate the system (100) and the cutting tool assembly (100) of the present disclosure in comparison to driving of vehicle until break-in of brake liner (6) is achieved. Consequently, break in time of brake liners (6) is also reduced. Additionally, newer vehicles may have efficient braking from day one of use without break in period resulting in lower accidents.

It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.).
