Description

Technical Field

[0001] The utility model belongs to the technical field of electronic braking, and particularly relates to a novel shock-absorbing rubber guide sleeve for electronic braking. Background Art

[0002] In electronic braking, information is transmitted through the brake pedal and the connecting rod. Since 1-box uses an electronic booster to replace the traditional vacuum booster, it has many advantages such as simple structure, low cost, fast braking response, high control accuracy, flexible layout, and consistent pedal characteristics. It is also easy to integrate with the vehicle dynamic control system, which can meet the regenerative braking system requirements of electric vehicles and hybrid vehicles and has good development prospects. With the development of electronic braking, compared with traditional braking, the vacuum booster cancels the direct connection between the brake pedal and the brake wheel cylinder. In the electronic braking system, when the brake pedal is pressed, information is transmitted to the 1-box through the brake pedal, which is connected to the metal parts through pins. When the metal parts move, abnormal noise will be caused. In order to solve the abnormal noise and increase the service life of the metal parts, it is necessary to add a shock-absorbing guide sleeve between the pin and the metal parts to isolate the poor performance caused by the collision between the metal parts.

[0007] As a preferred technical solution, both side end surfaces of the rubber sleeve are arranged as planes, and the inner bevel and the outer bevel are connected to a group of adjacent planes.

[0008] As a preferred technical solution, the inner bevel gradually approaches the central axis of the rubber sleeve from both ends to the center.

[0009] As a preferred technical solution, the outer inclined surface gradually moves away from the central axis of the rubber sleeve from both ends to the center.

[0010] The advantages of the utility model are: when the brake pedal is stepped on, the collision between the valve block and other assemblies will produce abnormal noise and reduce the performance of use, so a rubber sleeve is connected to the valve cover, the rubber sleeve has a good shock-absorbing effect and improves the performance of use; the end faces of the rubber sleeve on both sides are set to be flat, so that it can be assembled on both sides, reducing the risk of assembly errors caused by the need to identify the positive and reverse directions; the inner bevel and the outer bevel ensure that it is easier to insert the valve block into the rubber sleeve during assembly; the wavy edge design is more suitable for extrusion when the wall of the rubber sleeve is thick.

[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] Example 1

[0019] refer to Figures 1 to 4 , a novel shock-absorbing rubber guide sleeve for electronic braking described in this embodiment includes a rubber sleeve 1;

[0020] The brake system includes metal parts and pins 2. The metal parts include valve blocks 3 and other assemblies 4. When the brake pedal is depressed, the collision between the valve block 3 and other assemblies 4 will produce abnormal noise and reduce the performance. Therefore, a rubber sleeve 1 is connected to the outer surface of the valve 3. The rubber sleeve 1 is located between the valve block 3 and the assembly 4. The pin 2 is inserted into the valve block 3. The rubber sleeve 1 has a good shock-absorbing effect and improves the performance.

[0021] Both side end surfaces of the rubber sleeve 1 are configured as planes 14 so that the rubber sleeve 1 can be assembled on both sides, thereby reducing the risk of assembly errors caused by the need to identify the front and back directions.

[0022] The inner ring of the rubber sleeve 1 is provided with inner bevels 11 on both sides, and the inner bevels 11 gradually approach the central axis of the rubber sleeve 1 from both ends to the center. The outer ring of the rubber sleeve 1 is provided with outer bevels 12 on both sides, and the outer bevels 12 gradually move away from the central axis of the rubber sleeve 1 from both ends to the center. The inner bevels 11 and the outer bevels 12 are both connected to a group of adjacent planes 14. The inner bevels 11 and the outer bevels 12 ensure that the valve block 3 is more easily inserted into the rubber sleeve 1 during assembly.

[0023] A wavy edge 13 is arranged between the outer inclined surfaces 12 at both ends of the outer ring of the rubber sleeve 1. The wavy edge 13 includes an outer convex edge 131 and an inner concave edge 132 arranged alternately. The outer inclined surface 12 is arranged at both ends of the outer convex edge 131. When the rubber sleeve 1 is squeezed, the outer convex edge 131 is deformed, and the inner concave edge 132 can conveniently accommodate the part squeezed out of the outer convex edge 131. The design of the wavy edge 13 is more suitable for extrusion when the wall of the rubber sleeve 1 is thick.
