The invention relates to a stepless speed changer, belongs to the technical field of stepless speed change, and effectively solves the problems of limited transmission power, complicated structure and high manufacturing cost of the conventional stepless speed changer. A stator and a rotor which can rotate relative to the stator are arranged at the front end of a middle shaft; a rotor shaft of the rotor is fixedly arranged on the middle shaft; a stator shaft of the staor is sleeved at the foremost end of the middle shaft; the stator is fixedly connected with a tooth ring; the tooth ring is meshed with a planetary wheel; the planetary wheel is meshed with a sun wheel; the planetary wheel is sleeved on a planetary frame and is in rotating fit with the planetary frame; the planetary frame is sleeved at the rearmost end of the middle shaft; the sun wheel is fixedly arranged on the middle shaft and is positioned between the rotor shaft and the planetary frame; the stator is a power input end; and the planetary frame is a power output end. According to the magnetic differential stepless speed changer, a complicated speed change control system is not needed, so that the transmission power is not limited; and the magnetic differential stepless speed changer is simple in structure and low in cost. The magnetic differential stepless speed changer is suitable for the field of automobiles, internal combustion locomotives, tractors, mine machinery, road construction machinery, military equipment and the like.
Description
technical field [0001] The invention belongs to the technical field of continuously variable transmission, and relates to a continuously variable transmission, in particular to a magnetic differential continuously variable transmission. Background technique [0002] The existing continuously variable transmission for automobiles has two forms, one is to adopt V-shaped metal belt with variable diameter metal pulley CVT; the other is to adopt roller rotary disc type CVT. Both of the above two continuously variable transmissions belong to friction transmission, the transmission power is limited, and the transmission torque is 330N. m below, and are equipped with complex variable speed control system, complex structure, high manufacturing cost, the ability to transmit torque still needs to be further improved. And the above-mentioned continuously variable transmission has the phenomenon of stagnation and roughness when starting and running at low speed; when starting again afte...
