Mute drive chain system for motorcycle rear drive transmission and motorcycle

Abstract

The invention discloses a mute drive chain system for motorcycle rear drive transmission, and relates to the technical field of motorcycle chain transmission. The mute drive chain system comprises a small chain wheel, a large chain wheel and a mute drive chain, and the mute drive chain is a tooth-shaped chain and comprises an outer chain plate, an inner chain plate, a guide plate, a pin shaft, a sleeve and a damping seal ring; the sleeve is in interference fit with mounting holes of the inner chain plate and the guide plate and forms an inner chain link together with the inner chain plate and the guide plate, the pin shaft penetrates through the sleeve and is in clearance fit with the sleeve, two ends of the pin shaft are in interference fit with mounting holes of the outer chain plate and form an outer chain link together with the outer chain plate, and the damping sealing ring is arranged between the outer chain link and the inner chain link. Through innovative design of the mute drive chain and the chain transmission system of the motorcycle, the technical limitation of traditional chain transmission is overcome, the stability and low noise of the chain transmission system can still be kept when the motorcycle moves violently at a high speed, the requirements for individuation, low noise and high abrasion resistance of high-end motorcycles are met, and dangerous accidents can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of motorcycle chain transmission, which covers motorcycles driven by engines and electric motors, and in particular relates to a motorcycle rear drive chain transmission system and the motorcycle. Background technique [0002] At present, the rear drive transmission mode of the motorcycle mainly adopts a chain transmission, and the driving problem of the motorcycle is solved by the chain transmission between the output shaft of the engine and the rear wheel shaft. [0003] In the design of the prior art, the chain structure used in the rear drive transmission of the motorcycle is a roller chain. In addition to considering the characteristics of the chain transmission structure being simple, light and handy, low in cost and easy to maintain, another important reason is that the drive wheel is installed. The rear fork of the motorcycle will vibrate during violent movement, and the chain can be given a certain ...

AI Technical Summary

Problems solved by technology

[0005] With the increasing demand for large-displacement cruising, travel, off-road, competitive motorcycles and high-end high-speed electric motorcycles, the traditional chain drive system is difficult to meet the personalized low noise requirements of these motorcycles, especially for high-end electric motorcycles and High-end large-displacement motorcycles such as cruising, touring, and street running have more and more calls for reducing the transmission noise of the rear drive chain

Even though the patent "202020979030.2 A Noise-Reducing Sprocket for Transmission" adopts the rubber-coating design of the sprocket, which can buffer the impact of the roller and the gear teeth during the high-speed transmission of the chain, and reduce the transmission noise to a certain extent, but with the package With the decline of rubber cushioning capacity, its noise reduction ability is gradually decreasing, and it has not effectively solved the personalized low noise needs of high-end motorcycles.

In addition, when installing the chain, reserve too much chain tension margin, or when the chain wears and elongates too much after use, it will also increase the transmission noise of the chain transmission system, and will also cause the speedometer sensor to malfunction and aggravate the wear and tear. Hazards such as chain sprockets, chain coming off sprockets, etc.
