Description

A front shock absorber with an outer spring

technical field

The utility model relates to the technical field of shock absorbers, in particular to a front shock absorber with an outer spring.

Background technique

Shock absorbers are widely used in car bodies. When passing through uneven roads, although the shock absorbing spring can filter the vibration of the road surface, reduce the impact of the vibration on the car body, and provide comfort for the driver and passengers, the shock absorber can accelerate the frame and the body. Attenuate the vibration of the vehicle body and improve the ride comfort of the vehicle body. However, the shock-absorbing spring also has a reciprocating motion itself while absorbing shock. The existing front shock absorber cannot well restrain the reciprocating motion of the shock-absorbing spring, and the reciprocating motion of the shock-absorbing spring causes the body to bump and reduces driving comfort. In view of the above situation, the patent number is: CN212564193U discloses a front shock absorber with an outer spring, including a first horizontal bar, a shock-absorbing spring, a damping rod, etc. The driver and passenger provide comfort. During the vibration of the shock-absorbing spring, the expansion and contraction of the damping rod can suppress the bumps caused by the vibration of the shock-absorbing spring to the car body, thereby effectively improving the comfort of the driver and passenger; the damping rod includes a hydraulic cylinder The two ends of the hydraulic cylinder are fixed between the two third connecting plates through the connecting block. When the shock-absorbing spring vibrates, it drives the hydraulic cylinder to expand and contract repeatedly, and the oil in the hydraulic cylinder repeatedly flows from one cavity to the other cavity through the pores. During the flow process, the friction between the hole wall and the oil and the internal friction between the oil molecules form a damping force on the vibration, so that the vibration energy of the shock-absorbing spring is converted into the heat energy of the oil to dissipate, thereby inhibiting the vibration of the shock-absorbing spring to the car body. It can effectively improve the comfort of the driver and passengers.

However, the above shock absorber can only buffer the stress on a single vertical straight line, and in the actual process of vehicle body traveling, the actual applied stress often has various inclination angles. At times, it can only rely on its fixed connection components for rigid buffering, which affects the comfort of the driver and passengers; in addition, the hydraulic cylinder is used for damping buffering. Under the buffering action of the vehicle for a long time and multiple frequencies, the oil inside the hydraulic cylinder is easy to overflow, and Replacement costs are high.
