Short transverse is arranged, and, it is respectively provided with a contact (not shown) at the upper and lower two ends of this chute,
When upper and lower stop 17-5 touches contact, ball screw 17-4 stops continuing to touch to this immediately
The motion of some direction.
In above-mentioned embodiment, it is preferable that stub 16 is arranged on stub frame 15, and electronic
When wheel is installed on stub frame 15, the surface that this stub 16 is in this Electric Motor Wheel makes stub 16
Offset distance is zero, and then guarantees Electric Motor Wheel to remain at the peak of rotary drum 4 to contact, the most directly
Line is with when turning to, and this Electric Motor Wheel all can contact with the peak of rotary drum 4, it is possible to avoid because of stub
When 16 offset distances are not zero, the steering angle of Electric Motor Wheel is excessive makes tire depart from the highest of rotary drum 4
The test error that point is caused.
In sum, the testing stand of embodiment of the present invention has the advantage that
(1) road analogy, resistance simulation, car weight simulation, inertia simulation can be carried out；
(2) braking simulation can carry out mechanical braking, electricity regenerative braking and machinery and electricity feedback
Coupling braking simulation.
(3) during steering mechanism is capable of actual driving operating mode CircOlectric to time by side force
Simulation.
(4) during Vertical loading mechanism is capable of actual driving operating mode, Electric Motor Wheel is conducted oneself with dignity and is carried
The vertical load simulation heavily waited.
(5) by above-mentioned (1), (2), (3) and (4), it is possible to realize Electric Motor Wheel is double simultaneously
To loading analog test, inertia simulation and braking simulation, the meaning of its testing stand is more than only existing
(1), the single situation in (2), (3) or (4), drive a vehicle operating mode closer in reality, be conducive to
Improve the accuracy of result of the test.
These are only embodiments of the present invention, not thereby limit the scope of the claims of the present invention, all
It is the equivalent structure utilizing description of the invention and accompanying drawing content to be made or equivalence flow process conversion, or directly
Connect or be indirectly used in other relevant technical fields, be the most in like manner included in the patent protection of the present invention
In the range of.
