Novel bicycle speed reducer with power generation and speed reduction functions and utilizing water damping

Abstract

The invention discloses a novel bicycle speed reducer with power generation and speed reduction functions and utilizing water damping. The novel bicycle speed reducer with power generation and speed reduction functions and utilizing water damping comprises a support cross beam, wherein two telescopic rods are arranged on the lower end face of the support cross beam symmetrically with respect to the support cross beam, support rods are arranged on the lower sides of the telescopic rods, and damping devices are arranged on the sides, far away from the support cross beam, of the support rods. Thenovel bicycle speed reducer with power generation and speed reduction functions and utilizing water damping abandons the traditional design of hydraulic and pneumatic pressure speed reducers, and theliquid resistance principle is used for overcoming the amplitude generated when a spring rebounds; meanwhile, the rebound hardness of a shock absorber can be changed by adjusting the blade angle according to different environments of riders; besides, as the liquid resistance principle is used, a traditional shock absorption oil emulsification phenomenon does not occur, daily maintenance is more convenient, the service life is longer, and shock absorption abnormal sounds are avoided.

Description

technical field [0001] The invention relates to the field of shock absorbers, in particular to a novel bicycle reducer with functions of generating electricity and decelerating using water damping. Background technique [0002] The piston rod of the hydraulic shock absorber continuously performs telescopic movement in the cylinder body, and the shock absorber oil in the cylinder body continuously flows up and down through the valve plate in the valve body to buffer the impact force and reduce the turbulence. Because the cylinder volume is reduced when the piston rod is stretched into the cylinder, the cylinder cannot be filled with damping oil completely. Because of the damping oil in the cylinder can not be filled originally, the shock absorber also inevitably occurs oil leakage and other factors during use to cause oil loss, and the damping oil in the cylinder will become less and less. In this way, when the vibration is frequent and the amplitude of the vibration is larg...

Problems solved by technology

In this way, when the turbulence is frequent and the turbulence is large, the circulation of the shock absorbing oil in the cylinder is lagging behind, and a vacuum is likely to appear in the cylinder, and the piston will appear empty in the cylinder.

In addition, as a result of the mixture of oil and gas in the cylinder, the shock absorber oil is emulsified, the volume increases, and the piston can no longer work to the original lower position, so that the compression damping increases to an unacceptable value

Moreover, when the emulsified damping oil passes through the valve plate, it is easy to produce abnormal noise from noise and vibration.
