Description
Technical field
The invention belongs to light vehicle field, more particularly to a kind of two-wheel wheel rack device.
Background technology
The two-wheel stent of earliest prior art compact car lives the midfoot support of axle generally by support base, Ran Hou
The both ends installation wheel of axle, to form dual wheels, when using this dual wheels, generally requires and fixes support base, two
The axial direction of wheel can be also fixed, and wheel can not cause floating for one of wheel, lead with the inclination of vehicle frame during turning
Meeting disequilibrium, steering are extremely difficult when causing to turn.
To solve the problems, such as that it is difficult that two-wheel turns to, people use the wheel for connecting two sidecar wheels sidewards in a wheel shaft in recent years
One differential mechanism is installed to change the speed difference of the two of vehicle wheels rotating speed in turning among axis, two-wheel turning is solved to reach
When can disequilibrium, turn to the problem of difficult, but this kind installs the method for differential mechanism in Ackermann steer angle on the wheel shaft of wheel
Wheel still can not can also cause floating for one of wheel with the inclination of vehicle frame, lead to meeting disequilibrium during turning, turn
To extremely difficult.
A kind of two-wheel wheel forks with vibration damping of Patent No. 201620488812X are that the present inventor researches and develops improvement in the prior art
A kind of two-wheel wheel fork, although the two-wheel wheel fork between two wheel forks be equipped with crane span structure, and crane span structure the right and left setting wheel fork connect
It connects in the mounting hole of arm and is cased with the prismatic axle flexible connection of shock-absorbing spring on prismatic guide sleeve and the right and left wheel fork, therefore work as vehicle
When road is uneven in enforcement, prismatic axle can be done with the vibration of spring in the prismatic axle movable span of prismatic guide sleeve
Lower linear movement due to the structure design of prismatic axle, changes the design that a traditional wheel shaft connects two sidecar wheels sidewards, crane span structure wheel
The design of fork can not only play the enforcement of the alignment and balance in left and right two-wheeled direction, and can achieve the purpose that independent shock-absorbing again.
But spring sometimes will appear the problems such as compression is insensitive when two-wheel wheel fork is turned, and wheel still can not tilt during turning, can also
Cause floating for one of wheel, be just not achieved balance, it is unstable or can not solve to turn to difficult problem.
Invention content
The shortcomings that the purpose of the present invention is being directed in the prior art, and one wheel of Ackermann steer angle can be prevented by providing design
Son floats, and difficulty is turned to solve the sulky vehicle of existing two-wheel stent, can be with vehicle so as to fulfill the dual wheels in turning
The inclination of body and tilt, reach balance and stability, improve turn performance a kind of two-wheel wheel rack device.
The technical scheme is that：A kind of two-wheel wheel rack device, mainly by two axle blocks 12, be fixedly mounted on wheel shaft
Wheel carrier composition on seat 12 for installing the wheel shaft 13 of wheel and being connected on two axle blocks 12；It is characterized in that：It is described
