Problems solved by technology

[0002] At present, most bicycle transmissions on the market rely on the wheel disc installed on the central shaft to drive through the chain, and transmit the kinetic energy to the flywheel installed on the rear wheel shaft of the bicycle, and then drive the rear wheel of the bicycle to rotate through the flywheel. During the process, problems such as unlinking, breaking the chain, pinching the pants, and dirtying the underwear with lubricating oil are often encountered. Therefore, it is necessary to design a bicycle that does not need a chain

Embodiment Construction

[0015] The present invention will now be further described in conjunction with specific examples, and the following examples are intended to illustrate the present invention rather than further limit the present invention.

[0016] Such as Figure 1~2 The shown chainless bicycle based on cam and crank slider transmission includes a vehicle frame, front and rear wheels, and pedals 1. The rear wheel is fixed on the vehicle frame through the rear wheel shaft, and the lower end of the vehicle frame is provided with a wheel to drive the rear wheel to rotate. Transmission mechanism, transmission mechanism comprises the cam 2 that is fixed on the inner side of pedal 1, the crank 9 that is fixed on the rear axle, the connecting rod 8 that rear end is connected with crank 9 in rotation, the slide bar 4 that is connected with connecting rod 8 front end and rotating The roller 3 connected to the front end of the slide bar 4, the roller 3 is in circumscribed rolling connection with the ca...

Abstract

The invention relates to a chainless bicycle based on cam-crank-slide bar transmission. The chainless bicycle comprises a frame, a front wheel, a rear wheel and pedals. The rear wheel is fixed on the frame through a rear wheel axle, and a transmission mechanism driving the rear wheel to rotate is arranged at the lower end of the frame and comprises a cam, a crank, a connecting rod, a slide bar and a roller, wherein the cam is fixed on the inner sides of the pedals, the crank is fixed on the rear axle, the rear end of the connecting rod is rotatably connected with the crank, the slide bar is connected with the front end of the connecting rod, the roller is rotatably connected at the front end of the slide bar and is in circumscribed rolling connection with the cam, one side of the rear end of the slide bar is connected with a bearing through a short shaft, guide rails allowing the bearing to slide on are arranged in the frame between the rear axle and the pedals, a gas spring is connected to the short shaft, and the rear end of the gas spring is fixed on the frame. The chainless bicycle based on cam-crank-slide bar transmission has the advantages of simple structure, little friction force, time saving, high efficiency, less proneness to faults, capability of achieving chainless transmission to avoid chain falling and trousers clamping, high speed, easiness in maintenance and modification on an existing bicycle and the like.

Description

technical field [0001] The invention belongs to the field of vehicles, and relates to a chainless bicycle based on the drive of a cam and a crank slider. Background technique [0002] At present, most of the bicycle transmissions on the market rely on the wheel disc installed on the central shaft to drive through the chain, transfer the kinetic energy to the flywheel installed on the rear wheel shaft of the bicycle, and then drive the rear wheel of the bicycle to rotate through the flywheel. In the process, problems such as unlinking, chain breaking, trousers being caught, and lubricating oil dirtying underwear are often encountered. Therefore, it is necessary to design a bicycle that does not need a chain. Contents of the invention [0003] The technical problem to be solved by the present invention is: based on the above problems, the present invention provides a chainless bicycle based on cam and crank slider transmission. [0004] A technical scheme adopted by the pre...
