All-terrain vehicle sprocket buffer device

Abstract

The invention relates to a buffer device for a full-landform vehicle chainwheel, at least comprising a chainwheel, a fixing seat, several linings and screwing components, where one side of the chainwheel is provided with several holding parts, the holding part is equipped with the lining and the other side of the chainwheel is provided with the fixing seat, a rear wheel shaft can run through the fixing seat, the screwing component runs through the lining on the chainwheel to fix on the chainwheel by nuts, and with the help of the linings, it can absorb the offset of the chainwheel when a full-landform vehicle jumps or is shocked and prevents chain extension to prolong or broke the chain, thus improving the use function of the full-landform vehicle.

Description

【Technical field】 [0001] The invention relates to an all-terrain vehicle, in particular to a buffer device for the sprocket of the all-terrain vehicle. 【Background technique】 [0002] All-terrain vehicles 1, such as figure 1 Shown, mainly in frame unit 11, steering mechanism 12, front wheel 13, seat portion 14, rear wheel 15, and the power unit 2 that provides the power source of the all-terrain vehicle. The front of the vehicle frame 11 is pivotally connected to the steering mechanism 12, and a group of front wheels 13 are arranged below the steering mechanism 12. Behind the steering mechanism 12, a riding portion 14 is arranged on the vehicle frame unit 11. Below the riding portion 14 is power unit 2. The power unit 2, please refer to Fig. 2, at least includes an engine system 21, and a continuously variable transmission system 22 driven by the engine system 21, the continuously variable transmission system 22 drives the rear axle 24 by a chain 23, A group of rear wheel...

AI Technical Summary

Problems solved by technology

And because the known sprocket wheel 241 is directly fixed on the fixed seat 25 with the screw element S, as image 3 As shown, when the all-terrain vehicle hits the ground, due to gravity and the effect of the original shock absorber system of the all-terrain vehicle 1, the chain 23 between the final chainring 226 and the sprocket 241 has been in a tight state. People suddenly increase the throttle again, so that the engine system 21 and the continuously variable transmission system 22 output greater horsepower and torque, which will cause the chain 23 and the sprocket 241 to withstand huge torque instantly and produce deviation, and will make the chain 23 It is loosened by strong stretching, or even causes the fracture of the chain 23, and also causes damage or deformation of the sprocket 241, thereby affecting the normal driving of the all-terrain vehicle 1

Conventional all-terrain vehicle 1 cannot solve the above-mentioned vicious driving mode at all, and there is a need for improvement
