Double-spring rear shock absorber

An embodiment of the utility model discloses a double-spring rear shock absorber. The shock absorber comprises a damper and further comprises a first outer spring sleeved on the damper. A second outer spring with pre-pressure larger than the first outer spring is sleeved outside the first outer spring. The damper comprises a cylinder and a piston rod. An upper connector is arranged at an outer end of the piston rod and provided with a spring base. Upper ends of the first outer spring and the second outer spring are installed in the spring base. Lower ends of the first outer spring and the second outer spring are installed in the cylinder. The double-spring rear shock absorber comprises the first outer spring and the second outer spring, when load of a motorcycle is light, the second outer spring is mainly used for bearing and absorbing shock, and when load of the motorcycle is heavy, the first outer spring and the second outer spring conduct bearing and shock-absorbing together. The double-spring rear shock absorber can improve load-bearing capacity of the shock absorber, and meet shock absorbing requirements when the load of the motorcycle is heavy.
