Automobile calipers with anti-lock structure

Abstract

The utility model discloses an automobile caliper with an anti-lock structure, which comprises a shell, cavities I symmetrically arranged in the two sides of the shell and a flow channel arranged between the two groups of cavities I. In the braking process, if a wheel is about to lock, the cavity I and the flow channel are communicated with each other, the anti-lock structure of the automobile caliper can lock the wheel, and the anti-lock structure of the automobile caliper can lock the wheel. The brake assembly moves to one side of the communication channel under the action of oil pressure, at the moment, oil in the first cavity flows into the second cavity through the communication channel, after the oil enters the second cavity through the communication channel, the sealing assembly arranged in the second cavity is pushed to move, the sealing assembly overcomes the elasticity of the sealing assembly under the action of the oil pressure, and therefore the brake assembly is driven to move. When the brake assembly moves towards the flow channel, the flow channel is sealed, after the flow channel is sealed, oil cannot continue to be injected into the first cavity through the flow channel, the pressure in the first cavity is not increased any more, and the brake assembly cannot continue to move, so that the situation that the brake assembly exerts too large pressure on the brake disc is avoided, and wheels are prevented from being locked.

Description

Technical Field

[0001] This utility model relates to the field of vehicle braking technology, and in particular to automotive calipers with anti-lock braking systems. Background Technology

[0002] Brake calipers are devices in a braking system that work with brake pads to brake and decelerate the wheels. They are widely used in various motor vehicles and non-motor vehicles.

[0003] When braking, brake fluid pushes the brake pads to clamp the brake disc, thus producing a braking effect. If the front wheels lock up, the vehicle loses its steering ability and cannot turn. If the rear wheels lock up, the vehicle loses stability and skids. Therefore, a car caliper with an anti-lock braking structure is proposed to solve this problem. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] Automotive calipers with anti-lock braking systems include:

[0006] The outer shell has symmetrically arranged cavities on both sides and flow channels connecting the two sets of cavities. The top of the outer shell has an inlet pipe connected to the flow channels. Inside the outer shell and on one side of the flow channels, there is a cavity two connected to it. The side of cavity two away from the flow channels is connected to cavity one through a communication channel. A unidirectional flow outlet channel is provided between cavity one and a section of the flow channels located at the upper part of cavity two.

[0007] A braking assembly is disposed within the cavity one;

[0008] A sealing assembly is disposed within the second cavity;

[0009] In this process, oil is injected into cavity one through the flow channel, which pushes the brake assembly to move. When the brake assembly moves to the side of the connecting channel, the oil in cavity one enters cavity two through the connecting channel, which pushes the sealing assembly to move and seal the flow channel, effectively preventing the brake assembly from locking up as it continues to move.

[0010] As an improvement to the above technical solution, the brake assembly includes a piston slidably disposed in the cavity and a fixing rod fixedly disposed on the piston. The fixing rod passes through the outer shell and extends to the outside of the outer shell, and a friction plate is disposed on the section of the fixing rod extending to the outside of the outer shell.

[0011] As an improvement to the above technical solution, a spring is provided between the piston and the inner wall of the cavity.

[0012] As the improvement of the above technical scheme, the sealing assembly comprises a sealing plug slidingly arranged in the two cavities and matched with the flow channel, and a spring two arranged between the sealing plug and the inner wall of the second cavity.

[0013] The present application has the advantages of:

[0014] In the braking process, if the wheel is about to lock, the brake assembly will move to the side of the communication passage under the action of oil pressure, at this time, the oil in the first cavity will flow into the second cavity through the communication passage, and the oil entering the second cavity through the communication passage will push the sealing assembly arranged in the second cavity to move, and the sealing assembly will move to the flow channel direction under the action of oil pressure, and the flow channel will be sealed, and the oil cannot continue to flow into the first cavity through the flow channel, and the pressure in the first cavity will not increase, and the brake assembly cannot continue to move, thereby avoiding the brake assembly applying excessive pressure to the brake disc and preventing the wheel from locking.

[0019] In order to make the purpose, technical scheme and advantages of the present application more clear and explicit, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0020] The automobile caliper with anti-lock structure comprises:

[0021] A housing 10, which is internally symmetrical on both sides and is provided with a cavity 12 and a flow channel 11 communicated between the two cavities 12, the top of the housing 10 is provided with a liquid inlet pipe communicated with the flow channel 11, the housing 10 is internally and located on one side of the flow channel 11 and is communicated with a cavity 14, the cavity 14 is communicated with the cavity 12 on the side away from the flow channel 11 and is provided with a communication passage 15, the cavity 12 and the flow channel 11 are provided with a one-way liquid outlet passage 13 between the upper part of the cavity 14;

[0022] A brake assembly is arranged in the cavity 12;

[0023] A sealing assembly is arranged in the cavity 14;

[0024] Wherein, the oil is injected into the cavity 12 through the flow channel 11 to push the brake assembly to move, when the brake assembly moves to one side of the communication passage 15, the oil in the cavity 12 enters the cavity 14 through the communication passage 15 to push the sealing assembly to move and seal the flow channel 11, effectively avoiding the brake assembly from moving continuously and being locked.

[0025] Specifically, when the driver steps on the brake pedal, the oil pump of the brake system starts to work, referring to Figure 1 The oil is pumped into the flow channel 11 through the liquid inlet pipe, because the flow channel 11 is communicated with the two cavities 12, the oil will quickly fill the flow channel 11 and flow into the cavity 12, as the oil in the cavity 12 increases continuously, the pressure generated by the oil pushes the brake assembly to move, the brake assembly gradually approaches the brake disc, thereby realizing the braking of the vehicle, during the braking process, if the wheel is about to be locked, the brake assembly will move to one side of the communication passage 15 under the action of the oil pressure, referring to Figure 2At this time, the oil in the cavity one 12 will flow into the cavity two 14 through the communication channel 15, and after the oil enters the cavity two 14 through the communication channel 15, the sealing assembly arranged in the cavity two 14 will be moved, and the sealing assembly will move to the flow channel 11 direction under the action of the oil pressure, overcoming the elastic force of the sealing assembly, sealing the flow channel 11, and after the flow channel 11 is sealed, the oil cannot continue to flow into the cavity one 12 through the flow channel 11, and the pressure in the cavity one 12 no longer increases, so that the brake assembly cannot continue to move, thereby avoiding that the brake assembly exerts excessive pressure on the brake disc, preventing the wheel from being locked. In addition, the one-way liquid outlet channel 13 also plays an important role in this process. When the braking demand decreases and the driver releases the brake pedal, because the sealing assembly seals the part of the flow channel 11 connected with the cavity one 12, the oil pump can pump the oil in the cavity one 12 out through the liquid outlet channel 13, so that the brake assembly is reset, and because the oil in the cavity one 12 flows out, the sealing assembly returns to the initial position under the restoring force of the sealing assembly, so that the flow channel 11 is connected with the cavity one 12, so as to facilitate the next braking.

[0026] In one embodiment, the brake assembly includes a piston 20 slidingly arranged in the cavity one 12 and a fixed rod 21 fixedly arranged on the piston 20, the fixed rod 21 penetrates the shell 10 and extends to the outside of the shell 10, and the fixed rod 21 arranged on the outside of the shell 10 is provided with a friction plate 22. When the oil enters the cavity one 12, the oil pushes the piston 20 to move, and the piston 20 drives the friction plate 22 to move through the fixed rod 21. When the piston 20 moves to one side of the communication channel 15, the oil in the cavity one 12 enters the cavity two 14 through the communication channel 15.

[0027] In one embodiment, a spring one 23 is arranged between the piston 20 and the inner wall of the cavity one 12, and when the braking is stopped, the elastic force of the spring one 23 can help the piston 20 to move, so that the piston 20 automatically returns to the initial position.

[0028] In one embodiment, referring to Figure 3The sealing assembly comprises a sealing plug 31 slidably arranged in the cavity 2 and matched with the flow channel 11, and a spring 30 arranged between the sealing plug 31 and the inner wall of the cavity 2. When the oil in the cavity 1 enters the cavity 2 through the communication channel 15, the oil entering the cavity 2 generates a pushing force on the sealing plug 31. The pushing force overcomes the elastic force of the spring 30 and pushes the sealing plug 31 to move towards the flow channel 11. With the movement of the sealing plug 31, the flow channel 11 is gradually sealed. After the flow channel 11 is sealed, the oil cannot continue to enter the cavity 1 through the flow channel 11, and the pressure in the cavity 1 no longer increases, so the piston 20 of the brake assembly stops moving. When the braking is stopped, with the decrease of the pressure in the cavity 2, the elastic force of the spring 30 is gradually greater than the force of the oil on the sealing plug 31, the spring 30 pushes the sealing plug 31 back to the initial position, and the flow channel 11 is reopened for the next braking.

[0029] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit it.
