The shock absorber comprises an outer pipe and an inner pipe, the inner pipe is slidably sealed in the outer pipe, a piston rod is fixedly connected to the end, away from the inner pipe, of the outer pipe, a first piston and a second piston are slidably connected in the inner pipe, and the piston rod is fixedly connected to the end, away from the inner pipe, of the outer pipe. A first air chamber is formed between the second piston and the first piston, a second air chamber is formed between the second piston and the end of the inner pipe, and a limiting block used for preventing the second piston from moving towards the first piston is further arranged in the inner pipe. The second piston moves away from the first piston to reduce the volume of the second air chamber. Under the condition that the initial air pressure of the first air chamber is not changed, the air chamber volume of the first air chamber in the compression process can be adjusted by adjusting the initial air pressure of the second air chamber, so that the damping compression curve is adjusted, and then the damping hardness of the bicycle is adjusted.
本发明公开了一种减震器以及采用该减震器的前叉和自行车,所述减震器包括外管和内管,所述内管上滑动密封于所述外管中,所述外管远离内管的一端固定连接有活塞杆,所述内管中滑动连接有第一活塞和第二活塞,所述第二活塞与第一活塞之间形成第一气室,所述第二活塞与内管端部之间形成第二气室,所述内管中还设置有用于阻挡第二活塞朝第一活塞方向移动的限位块,当第一气室的气压大于第二气室的气压时,第二活塞背离第一活塞方向移动使第二气室体积减小。本发明在第一气室初始气压不变的情况下,通过调整第二气室的初始气压,可以调节第一气室在压缩过程中的气室体积从而调整减震压缩曲线,进而调节自行车减震的软硬。
