Problems solved by technology

[0002] The existing dual-clutch transmission needs to rely on the friction clutches in the two sub-transmission devices to cooperate with each other, and this cooperation requires very complicated control software
Moreover, when the two friction clutches operate at the same time, they wear out quickly, and the friction clutches are also prone to heat when they are frequently started.

Embodiment Construction

[0011] The overrunning clutch type dual clutch transmission includes a housing, a control device, and two sub-transmission devices that cooperate with each other, and each of the sub-transmission devices includes an input shaft, an output shaft, a friction clutch, a gear set, and a shifting mechanism that cooperate with each other, The input shaft or the output shaft at the two ends of the gear set of each said sub-transmission device is equipped with a one-way overrunning clutch.

[0012] see figure 1 and figure 2 , since the dual clutch transmission is a mature product, so figure 1 figure 2 The schematic diagrams of two kinds of dual-clutch transmissions are only simplified for the purpose of illustrating the position of the overrunning clutch, and the housing, control device and shifting mechanism are not shown.

[0013] It can be seen from the figure that the two sub-transmission devices use solid input shafts and output shafts. The input shaft of one sub-transmission...

Abstract

The invention discloses an overrunning clutch type double-clutch transmission. Input shafts or output shafts at two ends of gear groups of two sub speed-changing devices are provided with unidirectional overrunning clutches.

Description

technical field [0001] The invention belongs to the field of dual-clutch transmissions. Background technique [0002] Existing dual-clutch transmissions need to cooperate with each other by the friction clutches in the two sub-transmission devices, and this cooperation requires very complicated control software. Moreover, the simultaneous action of the two friction clutches wears out quickly during use, and the friction clutches also tend to generate heat when they are frequently started. Contents of the invention [0003] In order to solve the above-mentioned problems, the overrunning clutch type dual-clutch transmission includes a housing, a control device and two sub-transmission devices that cooperate with each other, and each of the sub-transmission devices includes an input shaft, an output shaft, a friction clutch, and a gear set that cooperate with each other. , shifting mechanism, the input shaft or output shaft at both ends of the gear set of each sub-transmissi...
