Brake pipeline of a wheel loader with radiator

Abstract

The invention discloses a wheel loader braking pipeline with a radiator, which belongs to the technical field of wheel loader braking. It includes a brake caliper body, the oil inlet of the brake caliper body is equipped with an inlet check valve, and the oil outlet of the brake caliper body is equipped with an outlet check valve; it also includes a radiator, and the oil outlet on the radiator is connected to The inlet one-way valve, the oil return port on the radiator is connected to the outlet one-way valve, and the oil filling port on the radiator is connected to a high-pressure oil source. The invention realizes the flow of the brake fluid from the brake caliper to the radiator without affecting the braking performance; the flow channel inside the radiator can ensure sufficient heat dissipation of the brake fluid; Cool down the brake caliper in time, and at the same time prevent the brake fluid from boiling, effectively prevent the formation of air resistance, greatly improve the braking performance of the loader, and improve the driving safety of the loader; it can be directly improved on the dry bridge brake system of the original loader, and installed It is convenient, 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 ...

AI Technical Summary

Problems solved by technology

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, and the high temperature is transmitted through the brake pad→brake caliper piston→brake fluid, which will easily cause the vaporization of the brake fluid to form air resistance

Air resistance will cause the brakes of the loader to be weak, and in severe cases, the brakes will fail, which will seriously affect the driving safety of the loader
