Problems solved by technology

[0003] Dual-motor transmissions are applied to new energy vehicles because they can improve the working efficiency of the vehicle. However, the commonly used dual-motor transmissions often use fixed speed ratios. The fixed speed ratio prevents the motors from working at the best economic point, making the utilization of the motors low rate

Abstract

The invention discloses a dual-motor transmission and a vehicle. The dual-motor transmission comprises a first motor, a second motor, a first clutch, a second clutch, at least one third clutch, an input shaft, an intermediate shaft, an output shaft, a first input gear pair, a second input gear pair, a high-gear gear pair and a plurality of groups of low-gear gear pairs, wherein the first motor is connected with the input shaft through the first input gear pair; the second motor is connected with the input shaft through the second input gear pair and the first input gear pair; the first clutch is connected to the second motor and is combined with or disconnected from the second input gear pair or the low-gear gear pair; the second clutch is fixedly arranged on the input shaft and is combined with or disconnected from the high-gear gear pair or the low-gear gear pair; and at least one third clutch is fixedly arranged on the input shaft and is combined with or disconnected from a plurality of groups of low-gear gear pairs. According to the dual-motor transmission, various speed ratios can be provided.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a dual-motor transmission and a vehicle. Background technique [0002] With the continuous development of new energy vehicle technology, the requirements for the transmission on the vehicle are getting higher and higher. [0003] Dual-motor transmissions are applied to new energy vehicles because they can improve the working efficiency of the vehicle. However, the commonly used dual-motor transmissions often use fixed speed ratios. The fixed speed ratio prevents the motors from working at the best economic point, making the utilization of the motors low rate. Contents of the invention [0004] The main object of the present invention is to provide a dual-motor transmission intended to provide multiple speed ratios. [0005] In order to achieve the above object, the dual-motor transmission proposed by the present invention includes a first motor, a second motor, a first clutc...
