Abstract

The invention discloses a single-axle hydraulic driving device for a large-sized mining dump vehicle. The single-axle hydraulic driving device comprises a first driving device for driving two front wheels of the vehicle to rotate and a second driving device for driving two rear wheels of the vehicle to rotate, wherein the two rear wheels of the vehicle are connected with each other through a rear driving axle; the second driving device is connected with the rear driving axle; the first driving device comprises a first engine and a first transmission system for driving the front wheels to rotate; an output shaft of the first engine is connected with a driving shaft of the first transmission system; an output shaft of the first transmission system is connected with the two front wheels of the vehicle respectively; the second driving device comprises a second engine and a second transmission system for driving the rear driving axle to rotate; an output shaft of the second engine is connected with the rear driving axle through the second transmission system. The single-axle hydraulic driving device is high in load bearing capacity and operability, and can be used for realizing front wheel separate driving, rear wheel separate driving or all-wheel driving of the mining dump vehicle.

Description

technical field [0001] The invention belongs to the field of mine dump trucks, in particular to a single-axle hydraulic drive device for large mine dump trucks. Background technique [0002] Large mining dump trucks are one of the important means of transportation for modern mining enterprises, and are specially used in large construction sites such as open-pit mines, quarries, and hydropower projects. Its work is characterized by short distance and heavy load. It is often loaded with a large electric shovel to go back and forth between the mining point and the unloading point. [0003] Large mining dump trucks can be divided into two types according to the transmission mode: hydraulic mechanical transmission dump trucks and electric transmission dump trucks. The power transmission route of the dump truck with hydraulic mechanical transmission is: engine→hydraulic torque converter→power shift gearbox→transmission shaft→rear drive axle→rear wheel. The power transmission rou...
