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
The invention belongs to the Variable Speed Technology field, relate to a kind of stepless speed variator, refer in particular to a kind of magnetic force differential variable-speed case.
Background technique
Existing automobile has two kinds of forms with stepless speed variator, and a kind of is to adopt V-arrangement metal tape reducing metal belt pulley variable speed device; Another kind is to adopt roller rotation plate type stepless speed variator.More than two kinds of stepless speed variators all belong to friction driving, transmission power is limited, driving torque and all is provided with complicated change control system below 330N.m, complex structure, manufacture cost is high, the ability of transmitting torque still needs further to improve.And unsmooth, not round and smooth phenomenon is arranged when above-mentioned stepless speed variator starting and low speed driving; When recurrence goes on foot after stopping in emergency, the phenomenon that occasional generation low speed can't start.
Summary of the invention
For the deficiency that exists in the background technique, the purpose of this invention is to provide a kind of change control system and magnetic force differential variable-speed case simple in structure of need not.
For achieving the above object, the invention provides following technological scheme: a kind of magnetic force differential variable-speed case, comprise jack shaft, gear ring, planet carrier, planet wheel and sun gear, front end at jack shaft is provided with stator and the rotor that rotates with respect to stator, be provided with rotor shaft between the rotor, rotor shaft is packed on the jack shaft, be connected with stator axis on the stator, stator axis is sleeved on jack shaft foremost, stator is fixedly connected with gear ring, gear ring and planet wheel engagement, planet wheel and sun gear engagement, planet wheel is sleeved on the planet carrier and with it and is rotatably assorted, planet carrier is sleeved on the rear-most end of jack shaft, described sun gear be packed on the jack shaft and be arranged on rotor shaft and planet carrier between, stator is power intake, planet carrier is clutch end.
Above-mentioned stator is connected with motor outward.
Above-mentioned planet carrier is connected with ransaxle outward.
Between the above-mentioned gear ring and jack shaft, be between planet carrier and the jack shaft and be rotatably assorted.
The present invention's beneficial effect compared to existing technology is:
1, the present invention does not need numerous and diverse change control system, automatically adapts to load change, and output torque and rotating speed are changed thereupon.
2, maximum transmission ratio of the present invention can arbitrarily be set, and when velocity ratio was 1:1, speed changer produced self-locking, does not participate in work, has improved transmission system efficiency, has obvious capable of saving fuel oil effect.
3, when magnetic force differential variable-speed case of the present invention starting and low speed driving without unsmooth, not round and smooth phenomenon; When recurrence goes on foot after stopping in emergency, but the low speed smooth starting.
4, the present invention also have simple in structure, volume is little, cost is low, has enlarged the stepless speed variator using scope.
