Description
Technical field
The invention belongs to special vehicle apparatus fields, and in particular to a kind of liquid of the independent suspension for underground coal mine vehicle
Press wheel hub drive.
Background technique
Underground coal mine large-tonnage assistant conveyance vehicle uses hydraulic power mode, and engine is power source, gearbox bending moment
Device power shifting realizes vehicle to run by transmission axis connection drive axle, but due to the condition by coal mine down-hole tunnel, vehicle body
Height and width are extremely restricted, and carry that big drive axle outer dimension is larger, and bodywork height and width all not can guarantee, this
Invention saves drive axle installation site, and size is small, and arrangement is convenient, can effectively reduce bodywork height underground coal mine large-tonnage auxiliary
Haulage vehicle, for component due to carrying out technological processing for explosion protection feature, outer dimension is larger, and most of vehicles do not set vibration insulating system, drives and relaxes
Adaptive is poor, and vehicle jolts and causes centainly to damage to cargo.The present invention solves large-tonnage assistant conveyance vehicle in underground coal mine
The problem of potted road surface damping performance difference when driving.Underground tunnel road of coal mine hollow is more, and protrusion is less, and the present invention is in structure
When design, guaranteeing double transverse arm initial positions lower inclination to the right of device, when by potted road surface, double transverse arms can be at level,
So that damping performance utmostly plays.
Existing underground coal mine heavy type assistant conveyance vehicle generally uses central radial type structure, and hydraulic cylinder is turned to, made
It is long at car body, turning radius is big, and underworkings is more narrow so that turning turn around it is time-consuming and laborious.
Summary of the invention
Central radial type structure is used to cause volume to increase and be not easy to arrange drive apparatus in the prior art for above-mentioned
Problem, the present invention provide a kind of hydraulic wheel side drive that equipment volume is effectively reduced by being equipped with driving device on tire
Dynamic device.
The technical scheme adopted by the invention is as follows: a kind of hydraulic Direct wheel drives of the independent suspension for underground coal mine vehicle
Device, including fixing seat and the tire being arranged on the outside of fixing seat, fixing seat one end passes through the double transverse arms and mine trolley being equipped with
Connection, and be equipped on the inside of fixing seat and be bonded Direct wheel drives horse with the motor that is driven to tire, the fixing seat and motor
It reaches.
Firstly, the present apparatus is a kind of wheel hub drive, including set of stationary body structure and external wheel is set
Tire.Structure based on the mine trolley, and the equipment in the present invention is mainly that the quadrangle position of mine trolley bottom is arranged in
It sets.Wherein, compared with prior art, in order to reduce the setting of drive apparatus, and it is set up directly on tire side, can not only subtracts
The setting of few drive apparatus, to save space；Simultaneously, additionally it is possible to keep its power output more direct, avoid using the prior art
In multiple transmission devices cause loss of the power transmission between engine and tire larger.The fixed frame and mine trolley
Connection, and motor is fixed on fixed frame, fixed frame can not be rotated around the rotation direction of motor revolving shaft.
Further, double transverse arms include the connecting rod that at least two groups are parallel to each other, and every group of the connecting rod head and the tail connect
