Multi-clutch gear shifting system special for motorcycle and use method of multi-clutch gear shifting system

Abstract

The invention discloses a special multi-clutch shifting system for motorcycles and a method for using the same, comprising: an input shaft, an output shaft, several groups of gear pairs meshing with each other; The secondary gear is set on the input shaft through the controllable clutch; several one-way clutches, the gears of each low-speed gear pair except the highest speed gear in several groups of the gear pairs pass through one of the one-way clutches. The clutch is sleeved on the input shaft. The present invention has a relatively simple overall structure, realizes a small-volume, low-weight shift system, can be used for motorcycles and mopeds, and is easy to produce and implement. Through the clutch, gear shifting without gaps can be realized, and automatic gear shifting and manual electronically controlled shifting can be realized without the operator having technical experience. At the same time, there is no gear impact in the shifting process, and the gears are shifted through the engagement of the clutch, which is smooth and prolongs the service life. Moreover, energy loss and calorific value are small during work.

Description

technical field [0001] The present invention relates to the technical field of a gear shifting system, in particular to a gear shifting system with multiple clutches. Background technique [0002] The existing shifting systems mainly include CVT stepless shifting, mechanical shifting, hydraulic torque shifting and dual-clutch shifting, etc. However, the existing shifting systems have the following problems: [0003] (1) CVT infinitely variable transmission relies on friction to transmit power, which has low efficiency and high torque performance is not easy to solve. [0004] (2) Mechanical shifting requires the operator to have certain technical experience, the operating threshold is high, and there is an interval between gear impact and no power output during shifting. [0005] (3) The size of the hydraulic torque converter is too large, the high-pressure liquid is difficult to seal, and the transmission system generates a large amount of heat. [0006] (4) Dual-clutch s...

AI Technical Summary

Problems solved by technology

[0003] (1) CVT infinitely variable transmission relies on friction to transmit power, the efficiency is low, and the performance of large torque is not easy to solve

[0004] (2) Mechanical shifting requires the operator to have certain technical experience, the operating threshold is high, and there are gear shocks and intervals of no power output during shifting

[0005] (3) The size of the hydraulic torque variable gear is too large, it is difficult to seal the high-pressure liquid, and the transmission system generates a lot of heat

However, its complex structure, extremely high production process requirements, harsh control system requirements, and too large volume are not suitable for applications with high size and space requirements.
