Abstract

The invention provides an integrated steering brake valve group for a mining dump truck and the mining dump truck applying the valve group. The valve group comprises an oil inlet module (1), a servicebrake pilot control module (2), an emergency brake pilot control module (3), a parking brake control module (4) and a steering pilot control module (5), wherein the oil inlet module (1) comprises anoil inlet (P0), a first one-way valve (11) and a filter (12) which are connected in sequence, the oil inlet (P0) is connected with a pressure output oil port of a steering brake pump, and an outlet ofthe filter (12) is connected with a first node (N1); the service brake pilot control module (2) comprises a rear service brake pilot control unit (21) and a front service brake pilot control unit (22); the parking brake control module (4) is connected with the first node (N1), a sixth oil inlet/outlet (P6) and an oil return port (T); and the steering pilot control module (5) is connected with thefirst node (N1), a seventh oil outlet (P7) and the oil return port (T). According to the embodiment, the reliability of the steering brake valve group can be improved, and the maintenance frequency and maintenance difficulty of the valve group are reduced.

Description

technical field [0001] The present disclosure relates to the field of hydraulic technology, in particular, to an integrated steering brake valve group for a mining dump truck and a mining dump truck using the valve group. Background technique [0002] At present, in the field of mining dump trucks, the steering, braking, and lifting functions of mining dump trucks are generally realized through the hydraulic system. The driver controls the steering wheel, hydraulic pedal brake valve, emergency brake button and parking The vehicle brake release button is used to realize the steering, service brake, emergency brake, and parking brake release functions of the mining dump truck. [0003] However, the valve group installation and pipeline connection of each system are basically independent, and the frame space of the mining dump truck is very limited, which makes the valve group installation of the hydraulic system cumbersome and the pipeline connection complicated. When a compo...
