The outside of interior ball pin 309；Right protection tube 308 is sheathed on the outside of ball pin 305 in the right side.By the way that left 307 He of protection tube is arranged
Right protection tube 308, realizes the protective action of internal ball pin.
With reference to Figure 10, corresponding left plate spring 901 is fixedly mounted respectively in the bottom of the left and right sides of transmission shaft 800
With right leaf spring 902；The rear and front end of left plate spring 901 is fixed with the corresponding position of car body respectively；Right leaf spring 902
Rear and front end fixed respectively with the corresponding position of car body.
By installing leaf spring, it can be improved the effectiveness in vibration suppression of carriage rigid axle suspension steering structure, realize good
Riding stability and riding comfort.
Carriage rigid axle suspension steering structure provided by the utility model, steering principle are as follows:
When steering wheel 201 rotates, steering column 202 is driven to rotate；When steering column 202 rotates, pass through the 10000th
Steering drive axle 203 is driven to section 204；When steering drive axle 203 rotates, is driven by the second universal joint 205 and turn to pedestal
206 rotations；When turning to the rotation of pedestal 206, band moving gear 303 is rotated；
When gear 303 rotates, moving left and right for horizontal direction is carried out with moving gear 303；
Wherein, when gear 303 is moved to the left, the synchronization of diverter left lever 400 is driven to transport to the left by left inside ball pin 309
It is dynamic, when diverter left lever 400 moves downward, by left outside ball pin 304 pull left steering section 600 around left goat's horn 801 to the left
Rotation；Meanwhile drive the right pull rod 500 of diverter to synchronize and move downward by ball pin 305 in the right side, when the right pull rod 500 of diverter to
When left movement, right turn section 700 is pulled to turn left around right goat's horn 803 by ball pin 306 outside the right side；Thus make left steering section 600
It turns left with right turn section 700, realizes left steering function.
The principle of right turn and the principle of left steering are identical, and details are not described herein.
Carriage rigid axle suspension steering structure provided by the utility model, in whole bridge+steel of low speed four-wheeled vehicle
On flat spring formula front suspension, using left and right duplex pull rod diverter, it is directly connected to left and right turn section, thus direct simultaneously by diverter
Driving left and right turn section turns to realize, has the advantage that
(1) this structure omits track rod compared with traditional structure, installs simpler, cost reduction.
(2) the left and right pull rod turned to is directly connected to left and right turn section, the accuracy, returnability, row stability when steering compared with
Lateral bracing strut+drag link steering structure is good.
(3) when debugging front-wheel and left and right turn angle, since diverter pull rod and outer ball pin use thread connecting mode, because
This, directly rotates the use length for adjusting diverter pull rod, has the advantages that adjustment more easily.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching should also regard the protection scope of the utility model.
