Air spring bicycle vibration damping method with additional air chamber and bicycle

Abstract

An air spring bicycle vibration damping method with an additional air chamber and the bicycle, the bicycle seat is installed on the swing arm, the swing arm is hinged on the front frame, and can rotate up and down around the hinge, the swing arm and the rear frame An air spring is installed in the middle, and part of the steel pipe of the rear frame is closed as an additional air chamber. An air channel is set between the air spring and the additional air chamber. According to the road conditions and the weight of the rider, the valve core can be manually rotated to change the air. The size of the channel, so as to realize the variable stiffness and variable damping of the air spring, so that the rider can obtain the ideal vibration reduction effect. The vibration-damping bicycle has simple structure, good vibration-damping effect, strong adaptability to road conditions and loads, is suitable for riding requirements on various road surfaces, and has more outstanding vibration-damping performance on unpaved roads.

Description

technical field [0001] The invention relates to a bicycle, in particular to an air spring bicycle vibration damping method with an additional air chamber and the bicycle. Background technique [0002] Although the existing bicycles have various improvements in appearance, their adaptability to the road surface, especially the uneven road surface in rural areas, lacks significant improvement for a long time. In recent years, some vibration-absorbing bicycles have appeared continuously. Such as the patent No. 92229172.1, the name is off-road bicycle and the patent No. 96202667.0, the name is shock-absorbing bicycle, the patent No. The front and rear damping devices are arranged, and a lot of work has been done on the damping of existing bicycles, and certain effects have been achieved. But they all still have certain defects: as the patented product whose patent number is 92229172.1, its rear rocker arm is a single tube, its bending strength is small, the shelf behind it cann...
