Problems solved by technology

[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 electrom

Embodiment Construction

[0012] The present invention lies in the special use of the motor whose inner rotor and outer rotor can rotate freely to achieve the purpose of variable speed and torque. It can be combined with fixed ratio gears, planetary gears, and Simpson type and Lavigne type double rows. Star gears are combined to form a variety of different forms of continuously variable transmissions. In the following, the device is combined with a gear with a fixed ratio to realize stepless speed change as an example. figure 2 to explain;

[0013] Choose a permanent magnet motor, the outer rotor 2 of the motor is connected with the engine as the power input end of the torque converter, the three-phase winding of the motor is on the outer rotor 2, and the output end of the three-phase winding is connected with the three-phase clamp on the right end surface of the outer rotor. The three sets of carbon brushes 3 are slidingly connected with the three slip rings respectively. The three sets of carbon br...

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...
