Abstract
Description
Technical Field
[0001] The utility model relates to an adjustable shock absorber, in particular to an inner and outer double-spring adjustable rear shock absorber, belonging to the technical field of shock absorbers. Background Art
[0002] Traditional rear shock absorbers are generally equipped with a shock-absorbing spring on each rear shock absorber to bear the load and absorb vibration. As customers' requirements for the comfort of rear shock absorbers continue to increase, double-spring rear shock absorbers with two springs installed on one rear shock absorber have been designed. They can be divided into parallel double-spring (or inner and outer double-spring) rear shock absorbers and series-connected double-spring (or upper and lower double-spring) rear shock absorbers.
[0003] After searching, a Chinese patent with publication number CN210265634U discloses an adjustable rear shock absorber with inner and outer double springs, including a lower rubber ring. The preload of the outer spring is adjusted by rotating the nut on the outer circle of the adjuster, and the preload of the inner spring and the outer spring is increased or decreased at the same time by rotating the adjuster, or the preload of the inner spring and the outer spring is adjusted by rotating the adjuster. The preload of the inner spring and the outer spring of the adjuster can adapt to different assembly reaction force requirements of the rear shock absorber to a greater extent.
[0004] Although the above scheme can adjust the preload of the inner spring and the outer spring, the inner and outer double spring adjustable rear shock absorber in the above patent cannot ensure the stability of the internal workpiece when the shock absorber is adjusted. The inner and outer double springs of the traditional shock absorber are set in the same direction, and the stability effect is poor during adjustment. For this reason, we provide an inner and outer double spring adjustable rear shock absorber to solve the above problems. Utility Model Content
