Stepless self-balancing variable speed drive disk unit of pedal type motorcycle

Abstract

The present invention relates to a pedal-type motorcycle stepless self-balancing speed-changing drive disk device. It is an improvement on existent pedal-type motorcycle belt-type stepless automatic speed-changing drive disk. It is mainly characterized by that the taper-face drive disk and taper-face slide disk of drive disk are improved into the spherical drive disk and spherical slide disk. The invented improvement can make the power produced by engine fuel oil and the power required for running speed thus obtaining maximum balance and smoothness.

Description

technical field [0001] The invention relates to a belt-type or pressure plate-type stepless automatic balancing variable-speed driving disk device, in particular to a stepless automatic balancing variable-speed driving disk device for a pedal motorcycle. Background technique [0002] Existing scooter motorcycles are equipped with a belt-type stepless automatic variable speed drive disc device, which impels the rollers in the conical sliding disc to throw off and squeeze the conical sliding disc under the action of centrifugal force through the rotation of the drive shaft, so that the conical surface slides The transmission radius of the drive belt between the disk and the cone surface drive disk increases, and at the same time, the transmission ratio changes to reduce the radius of the driven belt to achieve stepless automatic speed-up. But because the weight of the rollers in the tapered surface sliding disc is too light, all below 30 grams, the centrifugal force of the rol...

AI Technical Summary

Problems solved by technology

However, because the weight of the rollers in the tapered sliding disc is too light, all below 30 grams, the centrifugal force of the rollers is not large when driving, and it cannot promote the rapid increase of the driving radius of the driving belt to reduce the transmission ratio and speed up the driving quickly.

And the transfer contact between the conical driving disc, the conical sliding disc and the transmission belt is a conical surface, which cannot reasonably promote the required transmission ratio when the vehicle speeds up or decelerates, so the power generated by the fuel cannot be fully converted into the power required for driving. This is an important reason for the fuel consumption of existing pedal motorcycles; secondly, the tapered sliding disc of existing pedal motorcycles contacts with the axle sleeve under the centrifugal force of the roller and the force of pulling the belt by the spring force of the driven disc. The force of sliding left and right on the surface is not uniform, which impedes the left and right sliding of the tapered sliding disc and the bushing, and the stepless speed change will not be uniform, thus affecting the stability and speed of driving. The above factors constitute the existing pedal motorcycle. The main factors that cause the car's fuel consumption to be unstable and easy to break
