Automatic driving car deadweight is 150KG or so corresponding to automatic driving car test car chassis of the present utility model.Such as
Shown in Figure 17, when dolly chassis is bearing the weight within 150KG, pass through first bullet on automatic driving car test car chassis
Spring component 214 and second spring component 223 ensure that driving wheel 211 or universal wheel 221 do not inside contract.
As shown in figure 18, when the load weight on test car chassis exceedes certain load scope, i.e. test car
Chassis is in high load condition, and the upward overload power in the direction born is passed to electric machine assembly 212 by driving wheel 211, via electricity
The overload power born is delivered separately to the first runner assembly 213 and the first spring assembly 214 by thermomechanical components 212.First rotating group
The rotating shaft 2131 of part 213 produces rotation via the upward overload power of action direction, so as to which drive motor component 212 moves up;
The L-shaped spring bearer plate 2124 of electric machine assembly 212 also moves up via the effect of the upward overload power in direction, so as to drive first
The first spring washer 2141, the spring 2142 of spring assembly 214 move upwardly together, via second spring packing ring 2143 and nut
2144 fix, and it is flexible to ensure that spring 2142 occurs within the specific limits, it is achieved thereby that driving wheel 211 moves up, in formation
Contracting.Meanwhile the upward overload power in the direction born is passed to the second turning discreteness 222, the 4th connecting plate 2222 by universal wheel 221
Moved up by the upward overload power effect in direction, drive L-type second spring pressing plate 2223 to move upwardly together, so as to drive
The first spring washer 2141, the spring 2142 of first spring assembly 214 move upwardly together, it is achieved thereby that universal wheel 221 to
Upper movement, formation inside contract, that is, realize when the load weight on test car chassis exceedes certain load scope, test car
The wheel mechanism on chassis be driven wheel 211 and universal wheel 221 inside contracted so that high capacity by chassis body mechanism 10
Bear, so as to reduce the loss to the consumable accessory of wheel mechanism 20.
When dolly chassis is bearing about 200KG weight, that is, the automatic driving car tested bear a heavy burden about 50KG when, driving
Wheel 211 and universal wheel 221 can occur substantially to inside contract, and about inside contract 1.2cm.
When dolly chassis is bearing about 300KG weight, that is, the automatic driving car tested bear a heavy burden about 150KG when, drive
Driving wheel 211 and universal wheel 221 can occur all to inside contract, now dolly chassis directly contact face load-bearing so that high capacity is the bottom of by
Disc main body mechanism 10 is born, and so as to reduce the loss to the consumable accessory of wheel mechanism 20, protects driving wheel 211 and universal wheel 221.
As shown in figure 17, when again the load weight on test car chassis returns to the certain load scope that can be born
When, i.e., when dolly chassis bears the weight within 150KG, the spring 2142 in the first spring assembly 214 needs to restore to the original state, then
Via L-shaped spring bearer plate 2124 by under driving wheel 211 and the bullet of electric machine assembly 212 being connected with driving wheel 211, so as to drive first
The spring assembly 214 of runner assembly 213 and first is together under bullet.Wherein, the lateral part of L-shaped spring bearer plate 2124 is horizontal via first
231 spacing fixation of bar.Meanwhile the spring 2142 in universal wheel 221 needs to restore to the original state, then via the Z-shaped spring bearer plate 2223 of class
By under the bullet of the second turning discreteness 222.Wherein, the Z-shaped spring bearer plate 2223 of class is via the 223 spacing fixation of the 5th connecting plate, so that
Obtain test car chassis and return to normal use state.
