Description:FIELD OF THE INVENTION
[001] Present invention relates to a braking system. More specifically, the present invention relates to a rotating member for the braking system.

BACKGROUND OF THE INVENTION
[002] Conventional Anti-lock Braking System (ABS) units typically include a disc brake assembly. The disc brake assembly is provided with a rotor, said rotor is attached to a wheel hub. The rotor has a pair of opposed friction plates that are selectively engaged by brake shoes supported on opposite sides of the rotor for sliding movement relative thereto. The rotor has a barrel portion and a disc portion extending radially outwardly from said barrel portion. The barrel portion defines an inner surface having a groove. A tone ring having a step formed on said outer surface is positioned in the barrel portion, such that said step is aligned for engagement with a biasing element.
[003] The disc brake rotor along with the tone ring is typically attached to a wheel of a vehicle, such that the tone ring is disposed adjacently to a sensor. The tone ring is generally provided with a plurality of teeth. The plurality of teeth on the tone ring interacts with the sensor to generate a magnetic pulse during rotation of the wheel. A current is generated corresponding to the magnetic pulse, which is indicative of speed of rotation of the wheel.
[004] Further, for mounting the tone ring adjacently to the sensor, the tone ring is typically mounted to the wheel hub. In order to mount the tone ring to the wheel hub, a plurality of holes are required to be provided in the wheel hub as well as in the tone ring. The holes in the tone ring and the wheel hub are fastened, for mounting the tone ring onto the wheel hub. Such provision of holes onto the wheel hub impedes its structural strength and durability, which is undesirable. Moreover, the disc brake rotor and the tone ring are typically manufactured separately. Thus, a separate attachment mechanism is required for joining the tone ring with the disc brake rotor, thereby increasing the number of components in the ABS unit, this will increase the cost of providing the fasteners or any other attachment means. Additionally, the tone ring which are fastened to the wheel hub decreases the efficiency of the ABS unit, due to interference of interaction of the fasteners with the magnetic field generated with the sensor, which is undesirable. Also, a tightening torque is required to attach the tone ring with rotor and at the time of servicing of the vehicle due to space constraints there are chances of loose assembly of tone ring, which will hamper the efficiency of the sensors for generating the magnetic pulse.
[005] In view of the above, there is a need for a rotating member, that addresses at least some of the limitations mentioned above.

DETAILED DESCRIPTION OF THE INVENTION
[031] The present invention relates to a rotating member of a braking system. The rotating member comprises a rotor body capable of being mounted onto a hub of a ground touching member, and a first portion. The first portion is connected to a rotor body of the rotating member. In an embodiment, the rotating member is a disc brake rotor of the braking system, while the rotor body is a rotor disc body and the first portion is a tone ring attached to the rotor disc body.
[032] Figure 1 is a front view of a rotating member 100, in accordance with an exemplary embodiment of the present invention. The rotating member 100 is a disc brake rotor of a braking system. More specifically, the rotating member 100 is a disc brake rotor of an Anti-lock Braking System (ABS) unit of a vehicle. The rotating member 100 is adapted to reduce part count in the braking system or the ABS unit, thereby enhancing manufacturability and aesthetic appeal of the rotating member 100.
[033] The rotating member 100 comprises a rotor body 102 capable of being mounted onto a hub (not shown) of a ground touching member (not shown). In an embodiment, the ground touching member corresponds to a wheel of the vehicle. Accordingly, the hub of the ground touching member corresponds to the hub of the wheel or a wheel hub. The rotating member 100 comprises a central slot 130 capable of receiving an axle shaft of the wheel. The central slot 130 upon receiving the axle shaft, positions the rotating member 100 concentrically with the wheel.
[034] An attachment portion 132 is provided on the rotor body 102. The attachment portion 132 is provided radially outwardly to the central slot 130. The attachment portion 132 is adapted to engage with the wheel hub for securing the rotating member 100 with the wheel hub. The attachment portion 132 is defined with a radius R3 (hereinafter referred to as ‘third radius R3’) from a central axis A-A’. The third radius R3 corresponds to a radial width of the attachment portion 132 from the central axis A-A’. In an embodiment, the central axis A-A’ corresponds to the axis along a top-down direction (not shown) of the rotating member 100, in the front view of the rotating member 100.
[035] In an embodiment, the attachment portion 132 of the rotor body 102 comprises one or more openings 134. The one or more openings 134 are positioned around the central slot 130 and are adapted to engage with one or more slits (not shown) provided to the wheel hub. The engagement between the one or more openings 134 and the one or more slits secures the rotating member 100 with the wheel hub. In an embodiment, the one or more openings 134 and the one or more slits are engaged with one another through conventional engagement techniques known in the art such as a fastening technique, a clamping technique and the like. In an embodiment, the radial width of the attachment portion 132 is selected to accommodate the one or more openings 134.
[036] Further, the rotor body 102 comprises an outer portion 106. In an embodiment, the outer portion 106 is the outer most region of the rotor body 102 from the central slot 130. The outer portion 106 of the rotor body 102 corresponds to a braking surface of the rotating member 102. Accordingly, the outer portion 106 is positioned between a pair of brake pads (not shown), wherein the pair of brake pads engage with the outer portion 106 for reducing rotational speed of the rotating member 100 and consequently braking or decelerating the wheel. In an embodiment, the pair of brake pads are coupled to a brake lever (not shown). As such, actuation of the brake lever correspondingly operates the pair of brake pads for braking the wheel. Further, a plurality of vent holes 136 are provided circumferentially on the outer portion 106. The plurality of vent holes 136 are adapted to vent out heat generated during engagement with the pair of brake pads. Further, the outer portion 106 is defined with a radius R2 (hereinafter referred to as ‘second radius R2’) from the central axis A-A’. The second radius R2 corresponds to a radial width of the rotor body R2 from the central axis A-A’. In an embodiment, the attachment portion 132 is provided upto the outer portion 106. Thus, the third radius R3 is less than the second radius R2.
[037] The rotor body 102 further comprises an inner portion 104. The inner portion 104 corresponds to the region of the rotor body 102 adjacent to the central slot 130. In other words, the inner portion 104 corresponds to the region of the rotor body 102 between the central slot 130 and the outer portion 106. In an embodiment, the inner portion 104 acts as a region for accommodating a first portion 108 of the braking system or the ABS unit. As depicted in Figure 1, the inner portion 104 accommodates the first portion 108, by integrating the first portion 108 to the inner portion 104 of the rotor body 102. In other words, the first portion 108 is integrally provided to the rotor body 102 or the first portion 108 and the rotor body 102 form a unibody construction. In an embodiment, the first portion 108 is detachably mounted or attached to the inner portion 104 (for e,g. as shown in Figures 2-8). Such a construction of the rotating member 100 mitigates the requirement of attachment mechanisms for mounting the first portion 108 onto the rotor body 102, thereby reducing part count in the braking system. Consequently, enhancing manufacturability of the rotating member. Additionally, the plurality of locating portions 124 are provided on the inner portion 104 of the rotor body 102. Each of the plurality of locating portions 124 are adapted to facilitate concentric mounting of the first portion 108 onto the rotor body 102. In an embodiment, each of the plurality of locating portions 124 are protrusions that extends from the outer portion 106 towards the central slot 130. The first portion 108 is defined with a radius R1 (hereinafter referred to as ‘first radius R1’). The first radius R1 corresponds to a radial width of the first portion 108 from the central axis A-A’. In an embodiment, the attachment portion 132 is a portion provided in the inner portion 104 of the rotor body 102. As such, the attachment portion 132 may be a part of the inner portion 104 in the rotor body 102.
[038] In an embodiment, the first portion 108 comprises a central hole 108b (for e.g. shown in Figure 3). The central hole 108b is adapted to align with the central slot 130 for enabling the rotating member 100 to receive the axle shaft of the wheel. In an embodiment, the inner portion 104, the outer portion 106 and the attachment portion 132 are disc shaped portions on the rotor body 102.
[039] Further, referring to Figure 2 in conjunction with Figure 1, the position of the first portion 108 on the rotor body 102 is depicted. As illustrated, the first portion 108 disposed in the inner portion 104 ensures that the first portion 108 extends upto the outer portion 106. As such, the first radius R1 of the first portion 108 is less than that of the second radius R2 of the outer portion 106. In the present embodiment depicted in Figure 2, the first portion 108 is positioned between the attachment portion 132 and the outer portion 106. Thus, the first radius R1 of the first portion 108 is greater than the third radius R3 of the attachment portion 132 and less than the second radius R2 of the outer portion 106. Accordingly, the radial width of the first portion 108 is greater than the radial width of the attachment portion 132 and less than the radial width of the outer portion 106. In an embodiment, the first radius R1 of the first portion 108 is less than the third radius R3 of the attachment portion 132 (as shown in Figures 6, 8 and 10). In an embodiment, the first radius R1 of the first portion 108 is less than the second radius R2 and the third radius R3 (as shown in Figure 9).
[040] In an embodiment, the first portion 108 is a tone ring of the ABS unit. The first portion 108 is provided with a plurality of teeth 110. The plurality of teeth 110 are circumferentially disposed on the first portion 108 and interact with a sensor (not shown) such as a hall-effect sensor, provided on the wheel hub. The plurality of teeth 110 upon interaction with the sensor generates a current indicative of the rotational speed of the wheel. The current may be routed to a control unit (not shown) in the vehicle, which is adapted to determine the rotational speed of the wheel based on the magnitude of the current generated due to interaction between the plurality of teeth and the sensor.
[041] Figure 3 is an exploded view of the rotating member 100 depicting mounting of the first portion 108 on the inner portion 104. The inner portion 104 comprises a circular pocket 112 that is adapted to coaxially receive the first portion 108. In the present embodiment, the circular pocket 112 is an annular cutout provided in the inner portion 104 to define a stepped profile to the rotor body 102. As such, a thickness of the inner portion 104 is lesser than that of the outer portion 106. Due to such a construction or stepped profile defined due to the circular pocket 112, the first portion 104 is in flush or in levelled construction with the outer portion 106 upon mounting on the circular pocket 112. In an embodiment, the circular pocket 112 extends upto the outer portion 106 of the rotor body 102.
[042] In an embodiment, the first portion 108 is provided with one or more flanges 114. Each of the one or more flanges 114 extend radially outwardly from an outer peripheral surface 108a of the first portion 108. Also, each of the one or more flanges 114 engage with at least one of a plurality of circumferentially spaced lugs 116 provided on the inner portion 104 of the rotor body 102. As such, the radial outward extension of the one or more flanges 114 corresponds to the position of the plurality of circumferentially spaced lugs 116. In the present embodiment, one flange 114 extends from the outer peripheral surface 108a of the first portion 108. As such, the flange 114 can be oriented to engage any of the plurality of circumferentially spaced lugs 116 of the inner portion 104. Additionally, the plurality of locating portions 124 are provided between the plurality of circumferentially spaced lugs 116. In an embodiment, each of the plurality of locating portions 124 are protrusions that extends from the outer portion 106 towards the central slot 130. In the present embodiment, each of the plurality of locating portions 124 are rectangular protrusions.
[043] In an embodiment, each of the one or more flanges 114 is provided with one or more locking members 126 which are adapted to engage with at least one of the plurality of circumferentially spaced lugs 116. Thus, engagement between the one or more locking members 126 and the plurality of circumferentially spaced lugs 116 establishes engagement between the first portion 108 and the inner portion 104. In the present embodiment, each of the one or more locking members 126 is a clasp member which is adapted to engage with an inner periphery 116a of the circumferentially spaced lugs 116.
[044] In an embodiment, for mounting the first portion 108 onto the inner portion 104, the first portion 108 is aligned with the circular pocket 112. Subsequently, the one or more flanges 114 are aligned with the plurality of circumferentially spaced lugs 116. At this juncture, the one or more locking members 126 are engaged with the inner periphery 116a of the plurality of circumferentially spaced lugs 116, thereby mounting the first portion 108 onto the inner portion 104. In an embodiment, the one or more locking members 126 are engaged with the inner periphery 116a of the plurality of circumferentially spaced lugs 116 through press-fitting. In other words, the one or more locking members 126 are engaged with the inner periphery 116a of the plurality of circumferentially spaced lugs 116 through interference fit. Such a fitting between the first portion 108 and the rotor body 102 of the rotating member 100 mitigates need for fasteners, thereby simplifying construction, manufacturability and assembly.
[045] Referring to Figure 4 in conjunction with Figure 3, the position of the first portion 108 in the rotor body 102 of the rotating member 100 is depicted. In the present embodiment, the first portion 108 is positioned between the attachment portion 132 and the outer portion 106. Thus, the first radius R1 of the first portion 108 is greater than the third radius R3 of the attachment portion 132 and less than the second radius R2 of the outer portion 106. As such, the radial width of the first portion 108 is greater than the radial width of the attachment portion 132, and less than the second radial width of the outer portion 106.
[046] Figure 5 is an exploded view of the rotating member 100 depicting mounting of the first portion 108 on the inner portion 104, in accordance with an embodiment of the present invention. In the present embodiment, the inner portion 104 comprises the circular pocket 112 that is adapted to coaxially receive the first portion 108. The circular pocket 112 is an annular cutout provided in the inner portion 104 to define the stepped profile to the rotor body 102. As such, a thickness of the inner portion 104 is lesser than that of the outer portion 106. Due to such a construction or stepped profile defined due to the circular pocket 112, the first portion 104 is in flush or in levelled construction with the outer portion 106 upon mounting on the circular pocket 112. In the present embodiment, the radial width of the inner portion 104 is less than the radial width of the outer portion 106.
[047] Further, the first portion 108 is provided with the one or more flanges 114 that extend radially outwardly from the outer peripheral surface 108a of the first portion 108. Each of the one or more flanges 114 are adapted to engage with the plurality of circumferentially spaced lugs 116 provided on the inner portion 104 of the rotor body 102. In the present embodiment, five flanges 114 extend along the outer peripheral surface 108a of the first portion 108. Accordingly, the five circumferentially spaced lugs 116 are provided corresponding to the one or more flanges 114 for facilitating mounting between the first portion 108 and the inner portion 104. In the present embodiment, the plurality of circumferentially spaced lugs 116 are a projection that extends from the central slot 108. Thus, in the present embodiment, the plurality of circumferentially spaced lugs 116 along with the central slot 108 form a hollow portion in the rotor body 102 for receiving the first portion 108.
[048] Further, each of the one or more flanges 114 is provided with one or more locking members 126 which are adapted to engage with at least one of the plurality of circumferentially spaced lugs 116.

Subsequently, the one or more flanges 114 are aligned with the plurality of circumferentially spaced lugs 116. At this juncture, the outer peripheral surface 114a of each of the one or more flanges 114 engage with the outer periphery 116b of the plurality of circumferentially spaced lugs 116, thereby mounting the first portion 108 onto the inner portion 104. In an embodiment, the outer peripheral surface 114a of each of the one or more flanges engages with the outer periphery 116b of the plurality of circumferentially spaced lugs 116 through press-fitting. In other words, the one or more locking members 126 are engaged with the inner periphery 116a of the plurality of circumferentially spaced lugs 116 through interference fit. Such a fitting between the first portion 108 and the rotor body 102 of the rotating member 100 mitigates need for fasteners, thereby simplifying construction, manufacturability and assembly.
[050] Referring to Figure 6 in conjunction with Figure 5, the position of the first portion 108 in the rotor body 102 of the rotating member 100 is depicted. In the present embodiment, the first portion 108 is positioned upto the attachment portion 132. Thus, the first radius R1 of the first portion 108 is less than the third radius R3 of the attachment portion 132 and the second radius R2 of the outer portion 106. Such a construction ensures that the first portion 108 or the tone ring is enveloped by the wheel hub, upon mounting of the rotating member 100 onto the wheel hub.
[051] Figure 7 is an exploded view of the rotating member 100 depicting mounting of the first portion 108 on the inner portion 104, in accordance with an embodiment of the present invention.

[055] Referring to Figure 8 in conjunction with Figure 7, the position of the first portion 108 in the rotor body 102 of the rotating member 100 is depicted. In the present embodiment, the first portion 108 is positioned upto the attachment portion 132. Thus, the first radius R1 of the first portion 108 is less than the third radius R3 of the attachment portion 132 and the second radius R2 of the outer portion 106. Such a construction ensures that the first portion 108 or the tone ring is enveloped by the wheel hub, upon mounting of the rotating member 100 onto the wheel hub.
[056] In an embodiment, the first portion 108 is provided with a first thickness, and the rotor body being provided with a second thickness. In an embodiment, the first thickness is one of equal to or greater than or less than the second thickness.
[057] Referring to Figure 9, the position of the first portion 108 in the rotor body 102 of the rotating member 100 is depicted. In the present embodiment, the first portion 108 is radially over or above (when viewed in a front view of the rotating member 100) the outer portion 106. Thus, the first radius R1 of the first portion 108 is greater than the second portion R2 of the outer portion 106 and the third radius R3 of the attachment portion 132. As such, the radial width of the first portion 108 is greater than the radial width of the outer portion 106 and the attachment portion 132.
[058] Referring to Figure 10, the position of the first portion 108 in the rotor body 102 of the rotating member 100 is depicted. In the present embodiment, the first portion 108 is adjacently to the central slot 130. Thus, the first portion 108 is radially lower to the attachment portion 132 and the outer portion 106. Thus, the first radius R1 of the first portion 108 is less than the third radius R3 of the attachment portion 132 and the second radius R2 of the outer portion 106. As such, the radial width of the first portion 108 is less than the radial width of the attachment portion 132 and the outer portion 106.
[059] The claimed invention as disclosed above is not routine, conventional, or well understood in the art, as the claimed aspects enable the following solutions to the existing problems in conventional technologies. Specifically, the claimed aspect of mounting the first portion onto the inner portion of the rotor body mitigates the need for fasteners, thereby reducing part count, enhancing manufacturability and aesthetic appeal of the rotating member. Further, reducing the part count simultaneously reduces weight of the rotating member and also manufacturing costs. Further, elimination of fasteners in the rotating member mitigates localized stresses due to the fasteners and tightening torque problems associated therewith. Moreover, mitigating the fasteners improves serviceability of the rotating member. Additionally, interference fit between the first portion and the inner portion of the rotor body reduces complexity in assembly.
[060] While the present invention has been described with respect to certain embodiments, it will be apparent to those skilled in the art that various changes and modification may be made without departing from the scope of the invention as defined in the following claims.
