Novel labor-saving bicycle

Abstract

The invention discloses a novel labor-saving bicycle. The novel labor-saving bicycle comprises a rear wheel, a steel ring, wheel teeth, a hydraulic motor, a return tank, hydraulic pipes, a hydraulic tank, pedals, a hydraulic pump and a bicycle frame, wherein the rear wheel is arranged at the rear end of the bicycle frame, the steel ring with the wheel teeth is arranged on the rear wheel, the wheelteeth arranged on the steel ring are connected to the hydraulic motor through a gear, the gear is arranged on a driving shaft of the hydraulic motor, the hydraulic motor is communicated with the hydraulic tank and the return tank through the hydraulic pipes, the hydraulic tank and the return tank are communicated with the hydraulic pump through the hydraulic pipes, and the hydraulic pump is connected to the pedals. Compared with chain transmission adopted by a traditional bicycle, the novel labor-saving bicycle has the advantages that the driving force of the rear wheel is changed by the design, and a resistance arm becomes shorter, so that a labor-saving effect can be achieved; compared with the traditional bicycle, the novel labor-saving bicycle can run faster; a buffer pressure tank isdesigned, so that intermittent force application of a cyclist can be easily realized; compared with the traditional bicycle, the novel labor-saving bicycle has the advantages of being faster, more labor-saving and capable of realizing intermittent force application, so that the novel labor-saving bicycle can be more suitable for long-distance cycling; and the novel labor-saving bicycle can even be applied to a self-propelled tricycle, a pull truck and the like.

Description

technical field [0001] The invention relates to the technical field of bicycles, more specifically, it relates to a novel labor-saving bicycle. Background technique [0002] Traditional bicycles are driven by chains, which are rigid transmissions, without buffering and energy storage. They are also equipped with special brakes. The special brakes are actually to convert the energy of the bicycle into friction and consume it to achieve the purpose of braking. . Moreover, traditional bicycles generally rely on pedals to drive the rear transmission mechanism to drive the rear wheels forward. Generally, bicycles are divided into two categories. One is a fixed sprocket bicycle that does not have a speed change device and is driven solely by a sprocket and a chain. It is a variable speed bicycle with a transmission. At present, the bicycle has a single driving mode. Since the chain of the fixed-sprocket bicycle is fixed, when accelerating, the rider needs to push down hard, and ...

AI Technical Summary

Problems solved by technology

[0003] Therefore, present common bicycle all has the following disadvantages: there is no buffering process in the rear wheel of the power transmission, the brake does not store the kinetic energy of the exercise, does not utilize the power-assisted drive of the shock-absorbing bounce, and there is no mechanism for driving the front and the rear wheels separately, which makes cycling difficult. Those who work hard, so that bicycles, a green and environmentally friendly means of transportation, cannot be effectively promoted
