Problems solved by technology

Its disadvantages are: (1) The electric type requires DC power supply, motor inverter, etc.; (2) The hydraulic type requires special lubricating oil and pump valves, and the hydraulic system has high processing accuracy and high cost; (3) Mechanical type, such as The ECVT mechanical transmission installs the triangular metal belt on the pulley with variable working radius, and the speed ratio is changed by changing the radius of the pulley by hydraulic pressure. The steel belt has a large contact wear and high-speed transmission noise.

Abstract

An automatic permanent-magnet speed variator of car features that its input axle is connected to multi-pole external rotor, its output axle is connected to permanent-magnet internal rotor, the RE magnetic steels are regularly arranged on the surface of said internal rotor, and a displacement executing mechanism is used to change the relative distance between internal and external rotors to realize stepless speed variation. Its advantages are low vibration, uniform acceleration, saving oil and less pollution.

Description

technical field [0001] The invention relates to the field of automatic transmissions for automobiles, in particular, an output shaft of an engine is equipped with a multi-pole outer rotor and a rare-earth permanent magnet steel inner rotor for relative displacement changes to achieve the purpose of speed change. technical background [0002] At present, there are three common types of automatic transmissions for automobiles, (1) electric type, electric continuously variable transmission components are DC series motors (used in trolleybuses, and widely used in super-heavy dump truck transmission systems), (2) Hydraulic type, the transmission part of the continuously variable transmission is a hydraulic pitch changer. (3) Mechanical, mechanical continuously variable transmission is to use the transmission wheel with variable diameter to realize continuously variable speed. Its disadvantages are: (1) The electric type requires DC power supply, motor inverter, etc.; (2) The hyd...
