abstract
The utility model relates to a front shock absorber of a tricycle. The lower ends of the front fork tube and the shock absorber are provided with a U-shaped shock absorber rocker arm, the lower end of the front fork tube is hinged with one arm end of the U-shaped shock absorber rocker arm, the other arm end of the U-shaped shock absorber rocker arm is provided with a shaft assembly hole, and the lower end of the shock absorber is hinged with a lower lug arranged at the bottom between the two arms of the U-shaped shock absorber rocker arm. The hinge hole of the lower lug is not higher than the hinge hole of the front fork tube and the shaft assembly holes at both ends of the U-shaped damping rocker arm. The utility model reduces the position of the hinge support hole at the lower end of the shock-absorbing rocker arm, so that the distance between the hinge support hole at the lower end of the shock-absorbing rocker arm and the hinge support hole of the front fork tube is the smallest when there is no load and the largest when there is heavy load; It not only achieves the purpose of no-load comfort, but also increases the bearing capacity of the shock absorber.
