Description

Technical Field

[0001] The utility model relates to the technical field of brake disc installation, in particular to a brake disc leveling device. Background Art

[0002] The brake disc is a very important part of the car. The brake disc rotates with the rotation of the tire during the driving process of the car. When braking, the brake caliper clamps the brake disc to generate braking force, making the car move slowly or stop. Therefore, the installation accuracy of the brake disc is high, and it needs to be leveled to ensure that the end face runout of the brake disc is within the specified value, so as to achieve the best braking effect and reduce the noise and wear during braking.

[0003] For example, the Chinese utility model patent No. 201320122114.4 provides a brake disc leveling device, which is installed on the rotating shaft of the car when in use. By adjusting the adjusting bolt, the telescopic adjustment of the leveling block in the positioning pressure plate can be achieved, thereby achieving local adjustment of the brake disc in a certain direction to meet the high requirements of the brake disc on flatness.

[0004] However, since the offset position and offset amount of each brake disc are different during the installation process, after use, in order to avoid the position of the leveling block changing between two installations and affecting the installation accuracy, the existing brake disc leveling device needs to manually reset the positions of multiple leveling blocks, which leads to a decrease in the installation efficiency of the brake disc. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model proposes a brake disc leveling device to solve the technical problem raised in the above background technology. Since the offset position and offset amount of each brake disc are different during the installation process, after use, in order to avoid the position of the leveling block being changed between two installations and affecting the installation accuracy, the positions of multiple leveling blocks need to be manually reset, thereby resulting in a decrease in the installation efficiency of the brake disc.

[0006] To achieve the above object, the utility model provides the following technical solution: a brake disc leveling device, comprising a housing, a connecting disc connected to a vehicle axle is arranged on the housing, a plurality of circumferentially arranged leveling units are arranged in the housing, and the leveling units include:

[0007] A leveling block is slidably disposed on the shell, and one end of the leveling block protrudes outside the shell, and a first elastic member is disposed between the leveling block and the shell;

[0008] A screw rod is slidably and rotatably arranged on the housing along its axis, and one end of the screw rod is rotatably connected to the leveling block;

[0009] A block is slidably disposed in the housing, and one end of the block is provided with threaded teeth that are threadedly connected to the screw rod; and

[0010] The driving mechanism is arranged in the housing to drive the multiple groups of the card blocks to slide and reset.

[0011] In a preferred embodiment, a limiting member is disposed in the housing, and one end of the leveling block abuts against the limiting member.

[0012] In a preferred embodiment, the limiting member is a limiting nut.

[0013] In a preferred embodiment, the driving mechanism comprises:

[0014] A driving column, arranged on the clamping block;

[0015] A reset disk is rotatably disposed in the housing along its axis, and a plurality of groups of inclined grooves are provided on the reset disk, wherein the width of the inclined grooves is greater than the diameter of the driving posts, and the plurality of groups of driving posts are respectively clamped in the plurality of groups of inclined grooves;

[0016] A lever, disposed on the reset disk and extending out of the housing; and

[0017] A reset component is arranged in the housing and connected to the card block to drive the card block to reset.

[0018] In a preferred embodiment, the reset component includes:

[0019] a stopper, disposed in the housing; and

[0020] The second elastic member is arranged between the stopper and the clamping block.

[0021] In a preferred embodiment, a shielding cover is fixedly provided on one side of the shell, and a driving rod is provided at the end of the screw rod. The driving rod is rotatably and slidably provided on the shielding cover along its axis.

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] When the device is in use, after placing the brake disc in the installation area, the device can be fixed on the wheel axle of the automobile through the connecting disc, so that multiple groups of leveling blocks abut against the brake disc, and the screw is rotated. During the rotation of the screw, the leveling block is driven to slide along the axis of the shell through the threaded connection with the threaded teeth on the clamping block to level the brake disc. After the leveling is completed, the device is disassembled, and the multiple groups of clamping blocks are driven by the driving mechanism to slide away from the screw at the same time. Under the action of the first elastic member, the leveling block and the screw are reset. After the clamping block is reset, the threaded teeth at one end of the clamping block are screwed with the screw again. If the threaded teeth are misaligned with the threads on the screw, the screw only needs to be rotated in a small range to ensure that the threaded teeth are clamped on the screw. After leveling, there is no need to reset the leveling blocks one by one, which effectively improves the efficiency of the brake disc installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0036] Example:

[0037] like Figure 1 , 2 As shown in Figures 5 and 6, the utility model provides a brake disc leveling device, including a housing 101, a connecting disc 104 connected to the wheel axle of the automobile is arranged on the housing 101, a plurality of circumferentially arranged leveling units are arranged in the housing 101, and the leveling units include a leveling block 201 slidably arranged on the housing 101, one end of the leveling block 201 protrudes outside the housing 101, a shielding cover 105 is fixedly arranged on one side of the housing 101, a screw rod 203 is arranged on the housing 101, a driving rod 204 is arranged at the end of the screw rod 203, the driving rod 204 is rotatably and slidably arranged on the shielding cover 105 along its axis, and one end of the screw rod 203 is rotatably connected to the leveling block 201. A clamping block 301 is slidably arranged in the housing 101, and one end of the clamping block 301 is provided with threaded teeth threadedly connected to the screw rod 203.

[0038] After the brake disc is placed, the device can be fixed to the wheel axle of the car through the cooperation of the connecting plate 104 and the bolts, so that the leveling block 201 abuts against the brake disc, and then the screw rod 203 is driven to rotate by rotating the driving rod 204. During the rotation process, the screw rod 203 is threadedly connected with the threaded teeth at one end of the clamping block 301 so that the screw rod 203 can slide along its axis, thereby driving the leveling block 201 to slide along its axis on the housing 101 to level the brake disc.

[0039] like Figure 2 ,to Figure 5 As shown, in this embodiment, a first elastic member 202 is provided between the leveling block 201 and the shell 101, and a driving mechanism for driving the multiple groups of clamping blocks 301 to slide and reset is provided in the shell 101, and the driving mechanism includes a driving column 303 arranged on the multiple groups of clamping blocks 301, and a reset disk 401 is rotatably provided along its axis in the shell 101, and multiple groups of inclined grooves 402 are provided on the reset disk 401, and the multiple groups of driving columns 303 are respectively clamped in the multiple groups of inclined grooves 402, and a lever 403 is provided on the reset disk 401, and the lever 403 extends out of the shell 101.

[0040] During the leveling process, multiple groups of first elastic members 202 are compressed. After leveling, the lengths of multiple groups of leveling blocks 201 extending out of the housing 101 are different. In order to avoid the position change of the leveling block 201 affecting the accuracy of the subsequent brake disc installation, the reset disc 401 can be driven to rotate in the housing 101 by toggling the lever 403. During the rotation process, the reset disc 401 drives the clamping block 301 to slide through the cooperation of the inclined groove 402 and the driving column 303, so that the threaded teeth at one end of the reset disc 401 are separated from the screw rod 203 or clamped on the screw rod 203 again. When the threaded teeth are separated from the screw rod 203, the leveling block 201 is reset under the reset ability of the first elastic member 202. The width of the inclined groove 402 is slightly larger than the diameter of the driving column 303, so that the clamping block 301 has a certain activity space.

[0041] like Figure 2 , 4 As shown in FIG. 5 , in this embodiment, a limiting member 102 is disposed in the housing 101, and one end of the leveling block 201 abuts against the limiting member 102, and the limiting member 102 is a limiting nut. The setting of the limiting member 102 can limit the motion range of the leveling block 201, so that the leveling block 201 and the screw rod 203 are both moved to the initial position.

[0042] like Figure 3 , 4 As shown in Figures 5 and 6, in this embodiment, a reset assembly connected to the block 301 is provided in the housing 101, and the block 301 is reset by the reset assembly. The reset assembly includes a block 103 in the housing 101, and a second elastic member 302 is provided between the block 103 and the block 301. After the lever 403 is moved to drive the reset disk 401 to rotate, the lever 403 is released, and the block 301 is reset under the action of the second elastic member 302, and the reset disk 401 is reversed and reset, and the threaded teeth at one end thereof are again clamped on the screw rod 203, and if the threaded teeth are misaligned with the thread of the screw rod 203, the screw rod 203 can be rotated slightly to make the thread of the screw rod 203 match the threaded teeth at the end of the block 301, so as to facilitate subsequent use, thereby quickly leveling the positions of multiple groups of leveling blocks 201.

[0043] Specific usage and beneficial effects of the utility model:

[0044] When the device is in use, after the brake disc is placed in the installation area, the device can be fixed on the vehicle axle through the connecting plate 104, so that multiple sets of leveling blocks 201 abut against the brake disc, and the screw 203 is rotated. During the rotation process, the screw 203 drives the leveling block 201 to slide along the axis of the shell 101 through the threaded connection with the threaded teeth on the clamping block 301 to level the brake disc.

[0045] After the leveling is completed, the device is disassembled, and the reset disk 401 is driven to rotate by toggling the lever 403. During the rotation of the reset disk 401, the driving column 303 and the inclined groove 402 cooperate to drive the multiple groups of blocks 301 to slide away from the screw rod 203 at the same time, and the leveling block 201 and the screw rod 203 are reset under the action of the first elastic member 202. Then the lever 403 is released, and the block 301 is driven to reset under the action of the second elastic member 302. After the block 301 is reset, the threaded teeth at one end thereof are screwed with the screw rod 203 again. If the threaded teeth are misaligned with the threads on the screw rod 203, the screw rod 203 only needs to be rotated in a small range to ensure that the threaded teeth are clamped on the screw rod 203. After the leveling is performed, there is no need to reset the leveling blocks 201 one by one, which effectively improves the efficiency of the brake disc installation.

[0046] The basic principle and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
