Problems solved by technology

The existing clutches used in dual-motor hybrid hybrid systems directly follow the dry clutches in traditional automobiles, but dry clutches are limited by their structure, occupying a large space and weight, and have a large torque capacity. The disadvantages of limited and external actuator drive that require a large thrust limit the further improvement of the performance of the dual-motor hybrid hybrid system of the car, and become the bottleneck of the development of the dual-motor hybrid hybrid system.

Abstract

The invention discloses an electromagnetic tooth embedding type clutch used for achieving driving separation and reunion of a first motor and a second motor. The clutch comprises a joystick, an annular electromagnet, an armature, an elastic reset mechanism, a movable end face gear and a fixed end face gear, wherein the joystick is inserted in an inner cavity of a rotor of the second motor, the two ends of the joystick are located on the two sides of the rotor of the second motor respectively, a magnetic attraction mechanism and a mesh transmission mechanism are located on the end sides of the rotor of the second motor respectively, compact axial arrangement is achieved, and therefore space of the clutch is substantially saved, and structural compactness degree of the clutch is improved. The invention further discloses a two-motor hybrid power system, under the action of the structural characteristics of the electromagnetic tooth embedding type clutch, an engine, the first motor and the second motor can be coaxially arranged, and according to the arrangement mode, not only is the advantage that the structure is compact achieved, but also transmission efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automobile hybrid power, in particular to an electromagnetic tooth clutch and a dual-motor hybrid power system using the clutch. Background technique [0002] In the field of automotive hybrid power, most of them adopt a dual-motor hybrid system, which is formed by the linkage of the first motor and the second motor. A clutch is provided between the first motor and the second motor, and the switching of the pure electric, series or parallel driving modes of the dual-motor hybrid system is realized through the clutch state of the clutch. [0003] At present, there is no special clutch used between the first motor and the second motor in this field. The existing clutches used in dual-motor hybrid hybrid systems directly follow the dry clutches in traditional automobiles, but dry clutches are limited by their structure, occupying a large space and weight, and have a large torque capacity. The above shortco...
