Abstract

The invention relates to improvements in braking devices of wheel loader travelling wheels, in particular to a wheel loader braking device with double booster pumps. The wheel loader braking device comprises an air storage tank, brake assemblies, two brake air tubes and brake oil tubes. The brake air tubes are respectively connected with the air storage tank through check valves. One of the brake air tubes is sequentially connected with an unloading valve and an air compressing pump connector, and the other one of the brake air tubes is connected with a brake valve. A brake pedal is mounted at the control end of the brake valve. The booster pumps are connected with the output end of the brake valve. The output ends of the booster pumps are connected with the brake assemblies through the brake oil tubes. Specially, the output end of the brake valve is connected with two brake assemblies on the front side and two brake assemblies on the rear side through two booster pumps respectively. By the wheel loader braking device, the problem, that accidents are easily caused due to the fact that one booster pump controls braking of four travelling wheels, of existing braking devices of the wheel loader travelling wheels is solved; the wheel loader braking device is an improvement to the existing braking devices of the wheel loader travelling wheels.

Description

technical field [0001] The invention relates to the improvement of the braking device of the traveling wheel of the wheel loader, which is a double afterburner pump braking device of the wheel loader. Background technique [0002] The front and rear travel wheels of the wheel loader are equipped with braking devices. The braking device of the prior art wheel loader travel wheels is composed of an air compressor (installed on the diesel engine), an air storage tank, a brake pedal, and a brake valve. , afterburner pump, brake air pipe, brake oil pipe and brake assembly, the compressed air generated by the air pump is input into the air storage tank, the brake pedal controls the brake valve, the brake valve and the afterburner pump adopt the system The dynamic gas pipe is connected with the air storage tank in turn, and the other end of the afterburner pump is connected with the brake assembly through the brake oil pipe, and the brake disc in the brake assembly is connected wit...
