Heavy vehicle split-type combined brake disc

Abstract

This utility model belongs to the technical field of brake disc structure improvement, specifically relating to a split-type combined brake disc for heavy-duty vehicles. It includes a base disc body with a mounting hub. Multiple fan-shaped mounting platforms are provided on both the left and right side walls of the base disc body. The base disc body has insertion holes corresponding to each mounting platform. A friction block is placed on each mounting platform. One end of the friction block has a plug that matches the insertion hole, and the other end has a locking head. An arc-shaped retainer is detachably connected between two corresponding locking heads. This split-type combined brake disc for heavy-duty vehicles, by dividing the disc body into multiple smaller fan-shaped friction blocks, requires only the replacement of the corresponding fan-shaped friction blocks when the brake disc wears out, thus significantly reducing the maintenance cost of the brake disc.

Description

Technical Field

[0001] This utility model relates to a split-type combined brake disc for heavy vehicles, belonging to the technical field of brake disc structure improvement. Background Technology

[0002] Brake discs are one of the core components of a car's braking system. Their main function is to generate friction by clamping the brake disc with the brake caliper, thereby slowing down or stopping the vehicle. Because of the constant friction between the brake caliper's friction pads and the brake disc, the friction surface of the brake disc is easily worn down, especially in heavy vehicles where the friction surface wears out even faster. If brake discs are not replaced in time, it will inevitably affect the vehicle's braking performance and pose certain safety hazards. Most existing brake discs are one-piece molded structures, requiring the entire disc to be replaced, which undoubtedly increases the vehicle's maintenance costs significantly.

[0003] To address this, Chinese utility model patent CN212131133U discloses a split-type combined brake disc, including a mounting bracket; friction discs are fixedly connected to both surfaces of the mounting bracket by bolts. While this design reduces maintenance costs by requiring only the replacement of the friction discs on both sides of the mounting bracket when the brake disc is severely worn, the fact that the friction disc is a single unit means that replacing the entire friction disc will still result in higher maintenance costs. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a heavy vehicle split-type combined brake disc that can effectively reduce the cost of brake disc use and maintenance.

[0005] The heavy-duty vehicle split-type combined brake disc of this utility model includes a base disc body, on which a mounting hub is provided. Multiple fan-shaped mounting platforms are provided on the left and right side walls of the base disc body. The base disc body has insertion holes corresponding to each mounting platform. A friction block is placed on each mounting platform. One end of the friction block has a plug that matches the insertion hole, and the other end of the friction block has a locking head. Both left and right corresponding locking heads can be detachably and fixedly connected to the base disc body.

[0006] Furthermore, six mounting platforms are provided on both the left and right side walls of the base plate, and the six mounting platforms are evenly distributed in a circle.

[0007] Furthermore, the card head, mounting platform, and arc-shaped sleeve are all provided with corresponding threaded holes, and fastening bolts are connected to the threads inside the threaded holes.

[0008] Furthermore, it also includes an arc-shaped ferrule, which engages between two corresponding ferrules on the left and right sides. The arc-shaped ferrule also has threaded holes that correspond to and fit the fastening bolts.

[0009] Furthermore, the cross-section of the arc-shaped ferrule is C-shaped.

[0010] Working principle and process:

[0011] When the friction block wears out, you can remove the corresponding fastening bolts, then remove the corresponding arc-shaped sleeve, and then remove the worn friction block from the mounting table and replace it with a good friction block.

[0012] The advantages of this utility model compared with the prior art are:

[0013] The heavy-duty vehicle split-type combined brake disc of this utility model divides the disc body into multiple smaller sector-shaped friction blocks. When the brake disc wears out, only the corresponding sector-shaped friction blocks need to be replaced, thereby greatly reducing the use and maintenance cost of the brake disc.

[0021] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0022] Example 1:

[0023] like Figures 1 to 6As shown, the heavy-duty vehicle split-type combined brake disc of this utility model includes a base disc body 1, a mounting hub 2 on the base disc body 1, and multiple fan-shaped mounting platforms 9 on the left and right side walls of the base disc body 1. The base disc body 1 has insertion holes 6 corresponding to each mounting platform 9, and each mounting platform 9 has a friction block 3. One end of the friction block 3 has a plug 7 that is adapted to the insertion hole 6, and the other end of the friction block 3 has a clip 8. Both left and right corresponding clips 8 can be detachably and fixedly connected to the base disc body 1.

[0024] When the friction block 3 is worn, it can be removed from the mounting platform 9 by unscrewing its corresponding fastening bolt 5, and then replaced with a good friction block 3. Since only the worn friction block 3 needs to be replaced, the maintenance cost of the brake disc is greatly reduced.

[0025] Example 2:

[0026] like Figures 1 to 6 As shown, based on Example 1,

[0027] Furthermore, six mounting platforms 9 are provided on both the left and right side walls of the base plate 1, and the six mounting platforms 9 are evenly distributed in a circle. The structural layout is reasonable and the stability is good.

[0028] Furthermore, the clamp head 8, the mounting platform 9, and the arc-shaped clamp 4 are all provided with corresponding threaded holes 10, and fastening bolts 5 are connected to the internal threads of the threaded holes 10. The friction block 3 is fastened by the cooperation of multiple fastening bolts 5 and threaded holes 10, which has good structural stability and is easy to install and disassemble.

[0029] Furthermore, it also includes an arc-shaped retaining sleeve 4, which engages between the two corresponding retaining heads 8 on the left and right sides. The arc-shaped retaining sleeve 4 is also provided with threaded holes 10 that correspond to and are adapted to the fastening bolts 5. By clamping the retaining heads 8 with the arc-shaped retaining sleeve 4, the structural stability of the friction block 3 can be effectively improved.

[0030] Furthermore, the cross-section of the arc-shaped ferrule 4 is C-shaped.

They are only for the convenience of describing this utility model and do not require that this utility model must be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
