Description

Technical Field

[0001] This utility model relates to the field of braking device technology, and in particular to an electro-hydraulic parking mechanism. Background Technology

[0002] Regarding the unmanned braking system of wheeled tractors, some adopt an electronic brake caliper structure. Although it does not require brake fluid and brake lines, has a short response time, and can achieve individual braking of four wheels, the cost of each component and maintenance is high, and the adjustment of the brakes is relatively complicated.

[0003] Therefore, there is an urgent need for an electro-hydraulic parking mechanism that is simple, reliable, low-cost, can replace the existing electronic brake caliper structure, and can be flexibly adjusted according to braking requirements. Utility Model Content

[0004] The purpose of this utility model is to provide an electro-hydraulic parking mechanism that solves the problems of inconvenient braking adjustment and high cost of existing electronic brake caliper structures. The various technical effects of the preferred technical solutions provided by this utility model are detailed below.

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

[0006] This utility model provides an electro-hydraulic parking mechanism, comprising:

[0007] Mounting bracket, which is mounted on the vehicle frame, with its two ends respectively connected to the brake cylinder and the brake pump;

[0008] A sliding fork, which is fixedly connected to the piston end of the brake pump;

[0009] An elongated hole is provided through the sliding fork and along the extension / retraction direction of the brake cylinder. The extension / retraction end of the brake cylinder is detachably connected to the sliding fork through the elongated hole.

[0010] Preferred options also include:

[0011] Telescopic push rod, the telescopic end of the brake cylinder is connected to the telescopic push rod;

[0012] A connecting block is fixedly connected to one end of the telescopic push rod near the sliding fork and slidably connected inside the sliding fork. Fastening bolts pass through the elongated hole, the connecting block, and the elongated hole in sequence.

[0013] Preferred options also include:

[0014] A sliding groove is formed inside the sliding fork and communicates with the elongated hole, and the connecting block is located inside the sliding groove;

[0015] A through hole is formed on the connecting block, and the fastening bolt passes through the elongated hole, the through hole, and the elongated hole in sequence.

[0016] Preferred options also include:

[0017] A brake push rod is fixedly connected to the piston end of the brake pump, and the brake push rod is fixedly connected to the sliding fork.

[0018] Preferred options also include:

[0019] A connecting bracket, wherein the mounting bracket is mounted on the vehicle frame via the connecting bracket.

[0020] Preferred options also include:

[0021] A solenoid valve, which is connected to the brake cylinder.

[0022] Preferably, the brake push rod is welded to the sliding fork or connected by a thread.

[0023] In the technical solution provided by this utility model, the main function of opening an elongated hole on the sliding fork is to facilitate the adjustment of the connection position between the extension end of the brake cylinder and the sliding fork, thereby adjusting the pushing stroke between the brake cylinder and the brake pump to adapt to multi-action braking requirements. The piston end of the brake pump is pushed by the extension end of the brake cylinder, which in turn pushes the brake fluid through the oil pipe to each brake caliper, converting the brake fluid pressure into mechanical force, which pushes the brake pads against the brake drum to generate braking force. The adjustment of the pushing stroke between the brake cylinder and the brake pump extends or shortens the braking time. Overall, this application has a simple and reliable structure, low cost, and can replace the existing electronic brake caliper structure, and can be flexibly adjusted according to braking requirements.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] refer to Figure 1-2 A specific embodiment of this utility model provides an electro-hydraulic parking mechanism, comprising:

[0030] Mounting bracket 2 is mounted on the vehicle frame, and its two ends are respectively mounted to brake cylinder 3 and brake pump 4;

[0031] The sliding fork 7 is fixedly connected to the piston end of the brake pump 4.

[0032] An elongated hole 8 is provided through the sliding fork 7 and is positioned along the extension and retraction direction of the brake cylinder 3. The extension and retraction end of the brake cylinder 3 is detachably connected to the sliding fork 7 through the elongated hole 8.

[0033] Regarding unmanned braking systems for wheeled tractors, some employ electronic brake caliper structures. While these eliminate the need for brake fluid and brake lines, offer short response times, and enable individual braking of all four wheels, they suffer from high component and maintenance costs, and brake adjustment is complex. In this application, the elongated hole 8 on the sliding fork 7 facilitates adjustment of the connection position between the extension / retraction end of the brake cylinder 3 and the sliding fork 7, thereby adjusting the stroke between the brake cylinder 3 and the brake pump 4 to adapt to multi-action braking requirements. The piston end of the brake pump 4 is pushed by the extension / retraction end of the brake cylinder 3, which in turn pushes brake fluid through the oil lines to each brake caliper, converting the brake fluid pressure into mechanical force. This force drives the brake pads against the brake drum, generating braking force. Adjusting the stroke between the brake cylinder 3 and the brake pump 4 extends or shortens the braking time. Overall, this application features a simple, reliable, and low-cost structure that can replace existing electronic brake caliper structures and allows for flexible adjustment based on braking needs.
