Line between tie point constitutes deformable parallelogram, solves front-wheel caused upper bottom perpendicular to the ground as a result,
Shifting problem, so that the wheel of the left and right sides remains that two wheels are parallel in the case where generating relative displacement up and down.
When the vehicle is turning, since human body custom is to bend inner inclination, to change the position of centre of gravity of car, so that all vehicles
Wheel slope inwardly an angle [alpha], such human body also therewith slope inwardly an angle [alpha], as a result, because inertia effects generate centrifugation
Power reduces, and ensure that stability of the vehicle in turning.On the other hand, flat due to using more connecting rods to constitute in the utility model
At least there are 6 pivot points in row quadrilateral structure, therefore lateral force needed for being easy to adjust parallelogramming deflection, guarantee vehicle
Lateral twisting does not occur in normally travel, overall stability is good.
Preferred technical solution, the connecting rod are 2, respectively upper connecting rod and lower link, the upper connecting rod and lower link
Isometric and upper and lower parallel arrangement, the fixed bracket of upper and lower connecting rod and connecting rod, left goat's horn bracket, the rotation between right goat's horn bracket connect
Spindle is arranged in parallel with the length direction of vehicle frame.
In above-mentioned technical proposal, the transfer includes the steering column assembly that lower end is fixedly connected with bogie car, one
To steering linkage, described steering linkage one end is connect through universal ball end oscillating bearing with steering column assembly respectively, and steering linkage is another
One end is connect with left steering goat's horn and right turn goat's horn respectively through universal ball end oscillating bearing.By rotation bogie car band turn
It is rotated to column assembly, steering column assembly pulls the rotation of front-wheel, to obtain smaller angle of turn.
The technical solution of the utility model can be applied to electric vehicle, be adapted for use with the slide plate form with a pair of of front-wheel
On electric vehicle, electric vehicle can have a rear-wheel or two rear-wheels.
Since above-mentioned technical proposal is used, the utility model has the advantage that compared with prior art
1, the utility model is provided with the attachment device at least 2 connecting rods, each connecting rod and left sheep in steering mechanism
Line between angle support and the tie point of right goat's horn bracket constitutes deformable parallelogram, solve as a result, front-wheel with
Ground vertically caused by upper and lower displacement problem so that the wheel of the left and right sides is in the case where generating relative displacement up and down, always
Keep two wheels be it is parallel, ensure that vehicle turning when stability.
2, parallelogram sturcutre is constituted using more connecting rods in the utility model, at least there are 6 pivot points, therefore easily
The lateral force needed for adjusting parallelogramming deflection guarantees that lateral twisting, monolithic stability do not occur in normally travel for vehicle
Performance is good.
