Multifunctional electromagnetic stepless torque changing apparatus

Abstract

The invention relates to a multifunctional electromagnetic stepless torque conversion device, belonging to the field of a speed changer. The device adopts a motor which consists of an inner rotor, an outer rotor, a motor winding, a slip ring, a carbon brush and a carbon brush holder, wherein, the inner rotor, the outer rotor and the motor winding can freely rotate, the slip ring is connected with a winding terminal, and the carbon brush and a carbon brush holder are connected with the slip ring in a sliding way; when in the process of power transmission, any of the two rotors is taken as a power input end, and other one is taken as a power output end; due to the special use, the functions of stepless speed change, clutch, battery cell charge and energy recovery can be realized when the motor is in a power generation mode, and the functions of starting an engine and pure electric driving and combination driving can be realized when the motor is in a power-driven mode; therefore, when being matched with the engine and a gear for use, the stepless torque conversion device can replace a electric generator, a starting engine, the clutch and a flywheel, so as to have positive effects of small volume, low cost, high transmission efficiency, energy conservation, environmental protection, simple structure and convenient operation.

Description

Technical field: [0001] The invention belongs to the technical field of transmissions, and in particular relates to a multifunctional electromagnetic stepless torque converter. Background technique: [0002] At present, most automatic transmissions AT and continuously variable transmissions VCT use hydraulic torque converters. However, due to the low efficiency, complex process and high precision of hydraulic torque converters, it must have high-pressure oil as a medium to work. It cannot be controlled at any time when the transmission changes. In some occasions, electromagnetic clutches and electromagnetic slip clutches are used for torque transmission. The main difference between it and this device is that it cannot change torque when transmitting power, and it also needs an external power supply. The multi-functional electromagnetic stepless torque conversion device is a motor with both inner and outer rotors in a state of free rotation, and the torque is transmitted to c...

The main difference between it and this device is that it cannot change torque when transmitting power, and it also needs an external power supply. The multi-functional electromagnetic stepless torque conversion device is a motor with both inner and outer rotors in a state of free rotation, and the torque is transmitted to change the speed. twisted
