Problems solved by technology

[0004] i. Since there is no clutch mechanism between the input shaft S1 of the transmission TM and the rotor of the electric motor EM, the transmission connection between the electric motor EM and the transmission TM cannot be disconnected, and the impact of the electric motor EM on the transmission TM is very large during the shifting process of the transmission TM. The shifting process is not smooth; and
[0005] ii. Since the electric motor EM and the transmission TM are separately arranged, not only the shell structure of the electric bridge drive system for the vehicle is too complicated, but also the axial dimension of the entire electric bridge drive system is increased

Embodiment Construction

[0036] Exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present invention, but are not intended to exhaust all possible ways of the present invention, nor are they intended to limit the scope of the present invention.

[0037] In the present invention, "transmission coupling" refers to the connection between two parts that can transmit driving force / torque. If there is no special description, it can mean that the two parts are directly connected or connected through a gear mechanism so that the two parts can be connected. transmission of driving force / torque.

[0038] Such as figure 2 As shown, the electric bridge drive system for a vehicle according to an embodiment of the present invention includes an electric motor module (including an electric motor EM and a clutch C integrated togethe...

Abstract

The invention provides a vehicle electric bridge driving system and a vehicle comprising the electric bridge driving system, the electric bridge driving system comprises a motor module integrated witha motor and a clutch, and a rotor of the motor is selectively in transmission connection with an input shaft of a transmission through the clutch. Therefore, when the transmission of the bridge driving system shifts gears, the clutch is controlled to be separated to disconnect the transmission connection between the motor and the transmission, so that the motor does not impact the transmission inthe gear shifting process.

Description

technical field [0001] The present invention relates to the vehicle field, and more specifically relates to a vehicle electric bridge drive system and a vehicle including the vehicle electric bridge drive system. Background technique [0002] figure 1 is a schematic diagram showing a connection structure of a vehicle-use bridge drive system according to the prior art, which can be used for a pure electric vehicle, a hybrid vehicle, or the like. Such as figure 1 As shown, the electric bridge drive system for a vehicle includes an electric motor EM and a transmission TM. One end of the input shaft S1 of the transmission TM is coupled with the rotor of the electric motor EM, for example, through a spline transmission and is supported by the housings of the electric motor EM and the transmission TM. The transmission The other end of the input shaft S1 of the TM is fixedly connected with the sun gear of the planetary gear mechanism K of the transmission TM, and the sun gear sha...
