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
The present invention relates to the automatic gearbox field, is multipole outer rotor and rare-earth permanent magnet steel internal rotor to be housed on the output shaft of driving engine make relative displacement and change and reach the speed change purpose specifically.
Technical background
Present automatic gearbox, common have three kinds, (1) electric power formula, electric power formula stepless variable drive parts are that direct current series motor (is used for trackless trolley car, with in the superduty dumping car driving system extensive employing is arranged), (2) hydraulic type, the drive disk assembly of toric transmission is a hydraulic pitch device.(3) mechanical type, mechanical continuously-variable transmission are to utilize the variable power wheel of diameter to realize stepless change.Its shortcoming, (1) electric power formula needs direct supply, motor inverter etc.; (2) hydraulic type needs special lube and pump valve, oil hydraulic system working accuracy height, cost height; Shortcomings such as (3) mechanical type is contained in the triangle metal tape on the variable belt wheel of swinging radius wheel as the ECVT mechanical transmission, changes the belt wheel radius by hydraulic pressure and changes speed ratio, and the steel band contact wear is big, and the high speed rotational noise is big.
Summary of the invention
The present invention the automobile permanent magnet automatic transmission with hydraulic torque converter, be the 4th kind of stepless gearing method.Speed-changing mechanism, have the no touch wearing and tearing, simple in structure, dependable performance, low cost of manufacture, fuel-economizing reduces that blowdown is dyed etc., driving engine realizes that with output " flexibility " is connected transmission, and these two soruce of vibrationes of driving engine and chassis are separated, and can alleviate Vehicular vibration, improve vehicle riding comfort, make the vehicle start smooth acceleration even.Taked technical scheme by finishing above-mentioned purpose:
The present invention forms transmission device by input shaft by transmission device and internal rotor displacement actuating unit two parts, bent axle, and flange, bearing, multipole outer rotor is formed.Polar body displacement actuating unit, by the spline output shaft, the rare-earth permanent magnet steel internal rotor, bearing baffle, oil pump rod, bearing, housing is formed, its principle of work is passed through oil pump rod, the rare earth permanent magnet internal rotor is done straight reciprocating motion on the spline output shaft, multipole outer rotor produces changes of magnetic field by permanent magnetism internal rotor change in displacement, makes garden Zhou Yundong by means of bearing and output shaft, this need pass through the oil pump rod moving linearly, reaches the stepless change purpose thereby can change inner and outer rotors relative distance.
Description of drawings
Fig. 1 is a new structure diagrammatic sketch of the present invention.
The specific embodiment
The embodiment of the invention is described in detail in conjunction with the accompanying drawings.
Automobile permanent magnet automatic transmission with hydraulic torque converter of the present invention, by electronic control part 24, engine speed sensor 20, inner and outer rotors displacement pickup 21, throttle position sensor 22, magnetic pickup device 23, fluid control part 25 oil pumps 26, Cleaner 27, the permanent-magnet variable-speed device is made up of item 1-11 and mechanical transmission item 12-19 etc., physical construction mainly contains multipole outer rotor 5 rare-earth permanent magnet steel internal rotors 7, displacement actuating unit 9 by figure, one group of sun and planet gear 14,15,16, one group of multiple disk clutch 12 that advances, one group of reverse gear multi-disc drg 13, diff 17, main reduction gear driven gear 18, axle drive shaft flange 19 compositions such as grade.According to diagrammatic sketch, shown in input shaft 1 and output shaft 10 be coaxial, magnet steel 6 is to be arranged in respectively on the inner rotor face 7 regularly by number of pole-pairs.Multipole outer rotor and rare-earth permanent magnet steel internal rotor can be made into planar shaped, tubular, and taper, its tapered edges is 0～90 ° with axial angle when tapered, tapered edges is tubular when being 0 ° with axial angle, is planar shaped when being 90 °.Its tubular and taper can be made into n=1 ... n
nIndividual number of pole-pairs.
Internal rotor polar body displacement actuating unit is done straight reciprocating motion by oil cylinder 9, to change the relative distance of inner and outer rotors.
Utilize internal rotor 7 and outer rotor 5 relative shifts to change and realize its speed change, the variation of relative shift is to be realized by oil cylinder displacement actuating unit, is equivalent to common electrical magnetic clutch change exciting current size like this and reaches how much change magnetic flow.Thereby changed input shaft rotating speed n
1With the output shaft rotation speed n
2The variation purpose.Characteristics of the present invention are to utilize the effect of rare earth permanent magnet high-intensity magnetic field, make swivel with number of pole-pairs, produce the magnetic field coupling when rotated, under the effect of oil cylinder displacement actuating unit, change the inner and outer rotors distance and cause magnetic attraction to change, produce revolutional slip, thereby reach the speed governing purpose, above-mentioned this will be mixed computer controlled, just realizes the automatic guidance speed change.
The present invention has fuel-economizing, reduces exhaust pollution, the contactless wearing and tearing of gear, and noiseless, Long service life, and the advantages such as " flexibility " connection for transmission are arranged. This speed changer can be applicable to permanent magnetism The Related product of motor with stepless speed regulation and various lathe and mechanical stepless speed change transmission. Especially suitable Be used for ultra-high-speed low noise, the applications such as isolated vacuum transmission.
