Preferably, the adjusting spring is a rubber spring. Rubber spring is polymer elastomer, has little, the good, the stable advantage of mechanical properties of resilience of self-heating, uses the utility model discloses well long service life, and material cost are low.
Furthermore, a cushioning spring is sleeved on the cushioning oil cylinder. The cushioning spring is high in strength and good in resilience, on one hand, the cushioning oil cylinder can be effectively supported, and on the other hand, a good cushioning effect can be provided on a bumpy road surface.
Preferably, in order to enhance adaptability, the stand is a multi-section telescopic connecting rod, and the multi-section telescopic connecting rod is provided with an adjusting locking clamp. The length of the multi-section telescopic connecting rod can be changed after the adjusting locking clamp is loosened, and the adjusting locking clamp is screwed up again after the specified length is reached so that the length of the multi-section telescopic connecting rod is fixed.
The connecting block may be welded directly to the frame. Preferably, the connecting block is fixed to the frame by fastening bolts for easy mounting and free disassembly.
When the vehicle runs on a road surface with an uneven surface, firstly, the shock absorption oil cylinder can extend or shorten according to the road surface condition to reduce the impact force of the unevenness of the road surface on the fast running vehicle and reduce jolt; when the road surface has broken stones or inclines suddenly, the upright post can incline due to the fact that wheels press the broken stones or the inclined road surface, at the moment, two adjusting springs which are arranged by taking the axis of the upright post as a symmetrical shaft can relieve impact through compression and extension and accumulate elastic potential energy, and the upright post can return to the vertical position along with the elastic potential energy accumulated during the continuous running of a vehicle; according to the size of the broken stone and the inclination condition of the road surface, the two adjusting springs are in buffering fit with each other to compress and extend, and the upright post is promoted to return to the vertical position, so that severe jolt caused by that the wheels suddenly press the broken stone and slide along the surface of the broken stone is avoided, and the purpose of self-adaptive adjustment is achieved.
The utility model has simple structure design, the added parts are cheaper, the cost of the whole vehicle can not be increased, and the market is favorable for wide popularization and application; the automatic adjustment can be carried out according to the condition of the road surface when the vehicle runs on the uneven road section, the violent bumping degree of the vehicle is reduced, the riding comfort is improved, the bumping frequency is effectively reduced, the abrasion to the loss of the vehicle is reduced, the safety and the stability of the vehicle condition after long-term driving are ensured, the service life is prolonged, and the maintenance cost is reduced.
