Abstract
The utility model discloses a three-wheel electric car which comprises a car body, a car body back wheel bracket, two back wheel forks, two back wheels. The back wheel bracket consists of a longitudinal shaft horizontally extending backwards in a longitudinal direction, and a horizontal spreader beam which is in the clearance fit with the longitudinal shaft through a shaft sleeve; the back wheel forks are respectively arranged at two ends of the horizontal spreader; the back wheels are respectively arranged an axle shaft between the back wheel forks. The utility model has the advantages that the back wheel bracket is designed as a bracket which consists of a longitudinal shaft horizontally extending backwards in a longitudinal direction, and a horizontal spreader beam which is in the clearance fit with the longitudinal shaft through a shaft sleeve so that when a bumpy road is came across, since the horizontal spreader beam is hinged with the longitudinal shaft through a shaft sleeve, the frame will not generate the inclination force along with the inclination of the back wheel even through the horizontal spreader inclines along with the back wheel. Therefore, the stability of the car body is improved and the travelling safety is enhanced.
Description
Technical field
The utility model relates to three-wheel vehicle, especially relates to three-wheeled electric vehicle.
Background technology
Three-wheeled electric vehicle in the market, its rear wheel frame and vehicle frame are the structure that is fixed with one.Therefore, when running into rough road, will cause two trailing wheels not on same horizontal surface, gently then cause the car body concussion of jolting, heavy then cause and overturn overturning.
The utility model content
The three-wheeled electric vehicle that the utility model purpose is to provide a kind of rear wheel frame to regulate voluntarily according to the highland, road surface.
For achieving the above object, the utility model can be taked following technical proposals:
Three-wheeled electric vehicle described in the utility model, it comprises car body, described car body rear wheel frame constitutes by the horizontally extending backward longitudinal axis longitudinally with by axle sleeve and described longitudinal axis free-running fit bonded assembly cross-arm beam; Two rear wheel fork are separately positioned on described cross-arm beam two ends, and two rear wheels are separately positioned on the axletree between two rear wheel fork.
On described two rear wheel fork, be respectively installed with damping spring.
The steering shaft top of described car body carrier by universal coupling be connected towards direction of operating bevelled handlebar axis.
The utility model advantage is that described rear wheel frame is arranged to frame to be formed by the horizontally extending backward longitudinal axis longitudinally with by axle sleeve and described longitudinal axis free-running fit bonded assembly cross-arm beam; Like this when running into uneven road surface in the driving process, because the described cross-arm beam and the described longitudinal axis are hinged by axle sleeve, when therefore the cross-arm beam is with the rear wheel run-off the straight, vehicle frame can not produce tilting force with the inclination of rear wheel frame, improve the stability of car body greatly, thereby improved traveling security; Be respectively installed with damping spring on two rear wheel fork, when ground descends suddenly or during rise height, what rear wheel can steadily can be not stiff thereupon tilting yet pounds earthward, stability and safety more when vehicle is travelled in the bad place of road conditions; With the steering shaft top of car body carrier by universal coupling be connected to direction of operating bevelled handlebar axis, make handlebar nearer from the distance of human body, improved the safety of driving, and increased comfort level.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of rear wheel frame described in the utility model is to structural representation.
The specific embodiment
As shown in the figure, three-wheeled electric vehicle described in the utility model, it comprises car body 1, described car body 1 rear wheel frame is formed by the horizontally extending backward longitudinal axis 2 longitudinally with by axle sleeve 3 and the described longitudinal axis 2 free-running fit bonded assembly cross-arm beams 4; Two rear wheel fork are separately positioned on described cross-arm beam 4 two ends, and two rear wheels 5 are separately positioned on the axletree between two rear wheel fork, make car body 1 can not tilt along with the inclination of rear wheel frame; Be respectively installed with damping spring 6 on described two rear wheel fork, make the road surface just rise and fall when very big, the inclination that rear wheel frame also can be steadily increases safety; With the steering shaft top of described car body 1 carrier 7 by universal coupling 8 be connected to direction of operating bevelled handlebar axis 9, make handlebar nearer from the distance of human body, improved the safety of driving, and increased comfort level.
