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.

Abstract

The invention discloses a multi-clutch gear-shifting system and a using method thereof. The multi-clutch gear-shifting system comprises an input shaft, an output shaft, a plurality of groups of mutually meshed gear pairs, a controllable clutch and a plurality of one-way clutches, wherein gears of the gear pairs at highest-speed gears in the groups of gear pairs are installed on the input shaft through the controllable clutch in a sleeving mode, and gears of the gear pairs at low-speed gears in the groups of gear pairs except the highest-speed gears are installed on the input shaft through the one-way clutches in a sleeving mode. When the multi-clutch gear-shifting system is used, the whole structure is simple, the gear-shifting system is small in size and light in weight, can be used for motorcycles and mopeds and is easy to produce and implement. Gapless gear shifting can be achieved through the clutches, and the multi-clutch gear-shifting system does not require an operator to have technical experiences and can achieve automatic gear shifting and manual electrical control gear shifting. In addition, no gear impact is produced in gear shifting, the gear shifting is achieved through engagement of the clutches, the engagement is smooth, and the service life is prolonged. Furthermore, energy loss and heat quantity are small in work.

Description

technical field [0001] The invention relates to the technical field of a shifting system, in particular to a 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 continuously 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 are gear shocks and intervals of no power output during shifting. [0005] (3) The size of the hydraulic torque converter gear is too large, the high-pressure liquid is difficult to seal, and the transmission system generates a lot of heat. [0006] (4) Dual-clutch gear shifting. Existing aut...
