Bicycle with rear suspension avoiding vibration

Abstract

A bike with suspended back vibration damper for low pedaling energy loss, low kickback or pedal feedback, and low braking affection is disclosed. The vibration damper features no sag setting and buffer design. The bike with suspended back vibration damper is characterized by having low pedaling energy loss, low braking affection, low kickback or pedal feedback, low energy loss, good comfort and long life of the shock absorber no matter what standing or sitting.

Description

technical field [0001] The invention relates to a bicycle, in particular to a bicycle with a rear suspension shock absorber. Background technique [0002] Generally, for a bicycle frame with a shock absorber function, its performance indicators include pedaling energy loss, impact of braking on shock absorber action, smoothness of shock absorber action (comfort), and pedal kickback caused by shock absorber action (ie Kickback: avoidance). When the shock is in motion, the change of the chain length causes the crank and the pedal to be stretched backward, causing the rider to feel uncomfortable). [0003] Among them, the phenomenon that the brake affects the operation of the shock absorber: [0004] Before braking, as shown in Figure 1: [0005] ΣM PF =0 [0006] f R ×(a+b)=mg×b [0007] F R = b a + b mg [0008] When braking ...

AI Technical Summary

Problems solved by technology

However, when the rear wheel is impacted by the ground at the same time when pedaling, the ground impact cannot be effectively absorbed by the shock absorber due to the restraint of the chain tension, which will affect the comfort of the shock absorber

When standing and pedaling, the weight transfer effect makes the center of the rear wheel deviate further from the optimal point, which makes the suspension system unable to effectively reduce the energy loss when pedaling. In addition, the amount of RC changes is also quite large, resulting in the kickback of the pedal in this patent serious
