Abstract
The utility model discloses a four-wheel three-fulcrum electric tractor, which comprises a motor, a steering wheel, a speed reducer, a driving axle, two rear driving wheels, a steering column and a steering device, wherein the driving axle is connected with the speed reducer which is connected with the motor, the two rear driving wheels are disposed on the driving axle, the steering column is disposed below the steering wheel and connected with the same, and the steering device is connected with the steering column through a universal joint. A rotary shaft of the motor is connected with a brake. The steering device comprises a sprocket mechanism, a disk, a wheel carrier and two front steering wheels, wherein the disk is connected with the sprocket mechanism which is connected with the steering column through the universal joint, and the two front steering wheels are disposed on the wheel carrier which is connected with the end face of the disk. The four-wheel three-fulcrum electric tractor is simple in structure and fine in stability, and constant operational stability and safety of the electric tractor can be guaranteed by means of the brake for braking the motor.
Description
Technical field
The utility model relates to the electrically propelled traction vehicle field, specifically is a kind of four-wheel three fulcrum electrically propelled traction vehicles.
Background technology
At present, electrically propelled traction vehicle is generally used the three-wheel electrically propelled traction vehicle, and its shortcoming is that whole vehicle stability is bad, tumbles easily during turning.And adopt the motor-driven trailing wheel to advance, but motor will cause the problem that electric motor starting does not get up or motor speed is slow under the situation of voltage or electric weight deficiency, the relative tractor truck that just can not drive moves.The existing auto steerer that just has generally is after adopting steering wheel rotation; Drive the rotation of steering shaft and steering inner articulated shaft, this moment is transfused to deflector, passes to pitman arm through amplification with after slowing down; Passing to track arm and intermediate rod through steering drag link; Make two front-wheels deflection simultaneously certain angle, its complex structure, turning to wastes time and energy.
The utility model content
The technical matters that the utility model will solve provides a kind of four-wheel three fulcrum electrically propelled traction vehicles, and it is whole unstable to solve existing electrically propelled traction vehicle, and motor-driven is prone to the problem of difficulty.
The technical scheme of the utility model is:
A kind of four-wheel three fulcrum electrically propelled traction vehicles; Comprise motor and bearing circle, with motor bonded assembly retarder, with retarder bonded assembly drive axle, be arranged on the drive axle two and drive trailing wheels, be arranged at the bearing circle below and, be connected with drg in the rotating shaft of described motor with bearing circle bonded assembly steering column, through universal-joint and steering column bonded assembly steering hardware; Described steering hardware comprises through universal-joint and steering column bonded assembly chain-wheel mechanism, with chain-wheel mechanism bonded assembly disk, with disk end face bonded assembly wheel carrier be arranged at two steering front wheels on the wheel carrier.
Described drg is selected hand brake for use.
Described chain-wheel mechanism comprises with universal-joint bottom bonded assembly sprocket wheel and is wound in the chain on sprocket wheel and the disk.
The advantage of the utility model:
(1), the utility model front-wheel is 2, it has guaranteed the Stability Analysis of Structures of car load, and turns to the stable danger of overturning of having avoided;
(2), adopt the drg braking motor and make the driven by motor retarder drive two trailing wheels through drive axle; It has guaranteed under the situation of electric moter voltage or electric weight deficiency; Still can pass through the drg braking motor, reach the effect of starter motor, guarantee the tractor truck smooth operation and make;
(3), the steering hardware of the utility model is simple in structure, turns to stablely, and cost of manufacture is low.
Description of drawings
Fig. 1 is the upward view of the utility model.
Fig. 2 is the structural representation of the utility model steering hardware.
The specific embodiment
See Fig. 1, a kind of four-wheel three fulcrum electrically propelled traction vehicles comprise hand brake 1, with the rotating shaft of hand brake 1 bonded assembly motor 2, with motor 2 rotating shaft bonded assembly retarders 3, drive trailing wheels 5 with retarder 3 bonded assembly drive axles 4, be arranged on the drive axle 4 two;
See Fig. 2, also include bearing circle 6, be arranged at bearing circle 6 belows and with bearing circle 6 bonded assembly steering columns 7, through universal-joint 8 and steering column 7 bonded assembly steering hardwares; Steering hardware comprises through universal-joint 8 and steering column 7 bonded assembly chain-wheel mechanisms, with chain-wheel mechanism bonded assembly disk 10, with disk 10 end face bonded assembly wheel carriers 11, is arranged at two steering front wheels 12 on the wheel carrier 11;
Chain-wheel mechanism comprises and universal-joint 8 bottom bonded assembly sprocket wheels 9 and the chain 13 that is wound on sprocket wheel 9 and the disk 10.
Claims (3)
1. four-wheel three fulcrum electrically propelled traction vehicles; Comprise motor and bearing circle, with motor bonded assembly retarder, with retarder bonded assembly drive axle, be arranged on the drive axle two and drive trailing wheels, be arranged at the bearing circle below and, it is characterized in that: be connected with drg in the rotating shaft of described motor with bearing circle bonded assembly steering column, through universal-joint and steering column bonded assembly steering hardware; Described steering hardware comprises through universal-joint and steering column bonded assembly chain-wheel mechanism, with chain-wheel mechanism bonded assembly disk, with disk end face bonded assembly wheel carrier be arranged at two steering front wheels on the wheel carrier.
