Description

Technical Field

[0001] This utility model relates to the field of brake piston technology, and in particular to a high-performance graded shock-absorbing brake piston. Background Technology

[0002] The brake piston is located inside the brake caliper and is the device that pushes the friction pads against the brake disc. When the driver presses the brake pedal, the brake fluid is compressed and pushes the piston forward, which in turn pushes the brake pads into close contact with the brake disc, generating friction and converting the car's kinetic energy into heat energy, thereby achieving the purpose of deceleration or stopping.

[0003] Brake pistons are one of the key components of the braking system, playing an important role in ensuring vehicle driving safety. Although traditional brake pistons can meet basic braking requirements, they are prone to damage when subjected to external impacts due to their lack of good buffering protection. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-performance graded shock-absorbing brake piston.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-performance graded shock-absorbing brake piston includes a piston body, a brake pad is disposed below the piston body, the piston body and the brake pad are connected by six connecting rods, a buffer block is slidably disposed inside the brake pad, an auxiliary buffer rod is fixedly installed on the top of the buffer block, the auxiliary buffer rod is slidably inserted into the main buffer rod, and a connecting plate is fixedly installed on the top of the main buffer rod.

[0007] Six buffer columns are slidably inserted into the connecting plate. The top of the buffer column is fixedly connected to the bottom of the piston body. A stop is provided at the bottom of the buffer column. A first spring is provided on the outer sleeve of the buffer column. One end of the first spring is fixedly installed to the connecting plate.

[0008] In addition, a preferred structure is that a reinforcing ring is provided between the piston body and the brake pad, the reinforcing ring is fixedly connected to the connecting rod, and six locking blocks are provided on the inner wall of the inner ring of the reinforcing ring.

[0009] In addition, a preferred structure is that the connecting plate has six sliding holes, into which a buffer post is slidably inserted, and a stop block is engaged at the bottom side of the sliding hole.

[0010] In addition, a preferred structure is that the bottom surface of the connecting plate has six slots, and a locking block is locked in the slot.

[0011] In addition, a preferred structure is that the main buffer rod has an inner cavity, and grooves are provided on both sides of the inner cavity.

[0012] In addition, a preferred structure is that a second spring is fixedly installed on the top of the auxiliary buffer rod, and the top of the second spring is fixedly connected to the top of the inner cavity.

[0013] In addition, a preferred structure is that sliders are provided on both sides of the outer wall of the auxiliary buffer rod, and the two sliders slide within the groove respectively.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, the external impact force is diluted by the elastic buffering effect of the first and second springs, and the impact force will not directly act on the piston body, thereby protecting the internal structure of the piston body and facilitating practical use.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5A high-performance graded shock-absorbing brake piston includes a piston body 1, a brake pad 2 disposed below the piston body 1, the piston body 1 and the brake pad 2 are connected by six connecting rods 3, a buffer block 5 is slidably disposed inside the brake pad 2, an auxiliary buffer rod 10 is fixedly installed on the top of the buffer block 5, the auxiliary buffer rod 10 is slidably inserted into the main buffer rod 6, and a connecting disc 7 is fixedly installed on the top of the main buffer rod 6.

[0024] Six buffer pillars 8 are slidably inserted into the connecting plate 7. The top of the buffer pillar 8 is fixedly connected to the bottom of the piston body 1. A stop block 81 is provided at the bottom of the buffer pillar 8. A first spring 9 is provided on the outer sleeve of the buffer pillar 8. One end of the first spring 9 is fixedly installed to the connecting plate 7.

[0025] Meanwhile, a reinforcing ring 4 is provided between the piston body 1 and the brake pad 2. The reinforcing ring 4 is fixedly connected to the connecting rod 3, and six locking blocks 41 are provided on the inner wall of the inner ring of the reinforcing ring 4 to enhance the strength of the brake piston.

[0026] Furthermore, the connecting plate 7 has six sliding holes 72, into which the buffer post 8 is slidably inserted, and the stop block 81 is locked on the bottom side of the sliding hole 72 to prevent the buffer post 8 from dislodging from the sliding hole 72.

[0027] Meanwhile, the bottom surface of the connecting plate 7 has six slots 71, and a locking block 41 is installed in the slots 71 to limit the position of the connecting plate 7 and prevent it from swinging excessively under the action of the first spring 9.

[0028] Furthermore, the main buffer rod 6 is provided with an inner cavity 61, and sliding grooves 611 are provided on both sides of the inner cavity 61.

[0029] Meanwhile, a second spring 11 is fixedly installed on the top of the auxiliary buffer rod 10. The top of the second spring 11 is fixedly connected to the top of the inner cavity 61. When the auxiliary buffer rod 10 compresses the second spring 11, the second spring 11 dilutes the external impact force.

[0030] Furthermore, sliders 101 are provided on both sides of the outer wall of the auxiliary buffer rod 10. The two sliders 101 are slidably located in the slide groove 611. When the auxiliary buffer rod 10 is pushed by an external force, the sliders 101 make the movement of the auxiliary buffer rod 10 more stable.

[0031] In this embodiment, after the piston body 1 is subjected to the force of hydraulic oil, it will drive the brake pad 2 to move through the connecting rod 3. The brake pad 2 is in close contact with the brake disc, generating friction, thereby achieving the purpose of deceleration or stopping.

[0032] When subjected to external impact, the impact force acts on the buffer block 5, which in turn pushes the auxiliary buffer rod 10 to move upward within the inner cavity 61 of the main buffer rod 6. The slider 101 then moves upward within the groove 611, making the movement of the auxiliary buffer rod 10 more stable. This, in turn, compresses the second spring 11. Under the elastic buffering effect of the second spring 11, the impact force is diluted. When the impact force is too large, the second spring 11 is completely compressed, and the impact force acts on the main buffer rod 6. The main buffer rod 6 then drives the connecting plate 7 to move upward. The slot 71 at the bottom of the connecting plate 7 then leaves the locking block 41, and the connecting plate 7 compresses the first spring 9. Under the elastic buffering effect of the first spring 9, the remaining impact force is diluted. Under the elastic reset effect of the second spring 11 and the first spring 9, the locking block 41 is reinserted into the slot 71, and the buffer block 5 returns to the brake pad 2. The impact force will not act on the piston body 1, thus protecting the piston body 1.

[0033] In this invention, the external impact force is diluted by the elastic buffering effect of the first spring 9 and the second spring 11, and the impact force will not directly act on the piston body 1, thereby protecting the internal structure of the piston body 1 and facilitating practical use.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
