Hybrid electric drive underground mining car

Abstract

The invention discloses a hybrid electric drive underground mining car which comprises two front electric wheel units and two rear electric wheel units, wherein the four electric wheel units respectively and independently drive four wheels of a dumper and have complete interchangeability; the hybrid electric drive underground mining car comprises a front frame, a rear frame and a hinging body; the front frame is hinged to the rear frame through the hinge body; steering cylinders are respectively arranged on two sides of the hinge body and are used for hinging and steering of the car. The hybrid electric drive underground mining car disclosed by the invention has the advantages that by adopting wiring power, the operation speed of the equipment can be greatly increased and the production efficiency is increased; diesel-electric power is used for auxiliary standby power and the power of the diesel-electric power is one third of normal power, and thus the underground pollution can be greatly reduced; the finished car structure is simplified and the design and manufacture difficulties of driving parts are reduced; due to the adoption of a maintenance-free wheel-side driving motor, the reliability of the car is improved and the maintenance cost of the system is effectively reduced; the four electric wheel units can be freely interchanged, and thus a good interchangeability is obtained.

Description

technical field [0001] The invention relates to an electric transmission underground mining vehicle with dual power, in particular to an underground mining vehicle driven by four-wheel independent electric transmission. Background technique [0002] The underground mine car is the key equipment for the mining and transportation of the underground mine, and usually adopts the front and rear frame articulation type, that is, the front frame 11 and the rear frame 8 are connected by the hinge body 9, and the hinge body has a hinge point and a swing ring, wherein the swing ring allows The front frame 11 rotates independently relative to the rear frame 8, and the hinge point allows the front frame 11 to reach a steering angle of 45° relative to the rear frame 8, thereby realizing the steering function. When driving on uneven roads, all wheels are guaranteed to be in contact with the ground to maintain overall stability, passability and maximum productivity. [0003] At present, t...
