Problems solved by technology

CVT (Continuously Variable Transmission, continuously variable transmission) can have countless gears in theory, but in fact, problems such as the strength and life of the transmission belt and the slipping between the transmission belt and the pulley limit the transmission efficiency of the CVT, and also limit its performance. The ability to transmit large torque, so the industry rarely uses CVT on large-displacement vehicles, and DCT currently has up to seven forward gears

Abstract

The invention discloses a three-shaft clutch speed change device, which includes a speed change gear set, three clutch devices, at least one and at most three clutches, the speed change gear set includes a first input shaft, a second input shaft and a third input shaft, the first The second input shaft and the third input shaft are hollow shafts, the first input shaft is passed through the second input shaft which is a hollow shaft, the second input shaft is passed through the third input shaft which is a hollow shaft, and the three clutch devices They are respectively connected between the power output shaft and the first input shaft, the second input shaft and the third input shaft; the three clutches are respectively connected to any two of the power input part, power output part and transmission control part of the three clutch devices. Between them, it is used for selective engagement, so that the power drives the input shaft of the variable speed gear set at a constant speed. The invention can meet the multi-gear requirements of the vehicle on the limited structural size.

Description

technical field [0001] The present invention relates to the mechanical field, in particular to a power transmission device, in particular to a three-shaft clutch speed changer and a speed change assembly with the three-shaft clutch speed changer. Background technique [0002] At present, vehicle transmission-related technologies are vigorously developing toward multi-gear, and more gears mean that better power performance, lower energy consumption, higher transmission efficiency, and lower exhaust emissions can be obtained. At present, 8AT (Automatic Transmission, automatic transmission) has become the standard configuration of BMW cars. Compared with previous ATs, it has better power performance, lower energy consumption, higher transmission efficiency, and lower exhaust emissions. Precision, higher cost, more difficult to maintain, and some manufacturers are developing and assembling 9AT, or even 10AT. CVT (Continuously Variable Transmission, continuously variable transmi...
