Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, specific embodiments will be described in detail below in conjunction with the accompanying drawings. Here we take the brake pipeline of the left front axle of the loader as an example to describe in detail.

[0024] combine Figure 2 to Figure 4 As shown, a wheel loader brake pipeline with a radiator, the oil inlet of the brake caliper body 100 is equipped with an inlet check valve 300, and the oil outlet of the brake caliper body 100 is equipped with an outlet check valve 200 . The oil outlet on the radiator 400 is connected to the inlet one-way valve 300 , and the oil return port on the radiator 400 is connected to the outlet one-way valve 200 . The outlet check valve 200 can control the brake fluid to only flow from the brake caliper 100 to the radiator 400 . The inlet check valve 300 can control the brake fluid to only flow from the radiator 400 to the brake caliper ...

Abstract

The invention discloses a wheel loader brake pipeline with a radiator, and belongs to the technical field of wheel loader brake. The wheel loader brake pipeline comprises a brake caliper body, an inlet one-way valve is installed at an oil inlet of the brake caliper body, and an outlet one-way valve is installed at an oil outlet of the brake caliper body; the pipeline also includes a radiator; an oil outlet of the radiator is connected with the inlet one-way valve, an oil return port of the radiator is connected with the outlet one-way valve, and an oil filling port of the radiator is connectedwith a high-pressure oil source. On the premise that the brake performance is not affected, brake fluid flows from the brake caliper to the radiator; a flow channel in the radiator can guarantee sufficient heat dissipation of the brake fluid; the brake caliper can be cooled in time under the working condition that the brake is frequently used for a long time; meanwhile, brake fluid can be prevented from boiling, air resistance is effectively prevented from being formed, the brake performance of the loader is greatly improved, and the traveling safety of the loader is improved; the pipeline can be directly improved on the basis of an original loader dry axle brake system, and is convenient to install, low in cost and easy to implement.

Description

technical field [0001] The invention relates to the technical field of braking of a wheel loader, in particular to a braking pipeline of a wheel loader with a radiator, which is suitable for a wheel loader with an air cap oil type dry brake. Background technique [0002] At present, most of the domestic loaders are equipped with dry axles, and the air cap oil brake system is generally used. [0003] Such as figure 1 As shown, it is the schematic diagram of the traditional loader brake pipeline, which is mainly composed of foot brake valve 001, air storage tank 002, afterburner pump 003, and brake caliper 004; [0004] Most of the wheel loaders are used for short-distance shoveling operations. The working distance is short, the cycle is fast, and the brakes need to be stepped on frequently. For loaders with this type of structure, the temperature of the brake disc is very high after frequent use of the brakes for a long time. The high temperature is transmitted through the ...
