The invention discloses a reliably-operating automobile transmission device comprising a universal transmission module and a transmission circuit. The universal transmission module is electrically connected with the transmission circuit. The universal transmission module comprises a universal joint, a transmission shaft and a transmission chain. The universal joint is made of shape memory alloy. The transmission shaft is connected with a sliding spline device composed of a sliding fork and a splined shaft. The reliably-operating automobile transmission device is simple in structure and convenient to produce, and operates reliably.
Description
Technical field
The present invention relates to a kind of automotive trannsmission system of reliable operation, particularly a kind of simple in structure, easily manufactured, the automotive trannsmission system of the reliable operation of reliable operation.
Background technology
Universal-joint is Hooke's coupling, and English name universal joint is the parts of realizing varied angle transmission of power, and for changing the position of transmission axis direction, it is " joint " parts of the universal driving device of automobile driving system.Universal-joint and transmission shaft combination, be called card gear.
The structure of universal-joint and effect are a little as the joint in human limb, and the angle between the part that it allows to be connected changes within the specific limits.For meeting transmission of power, adapt to the angle that the bob that produces while turning to automotive operation causes and change, the drive axle of front drive automobile, between semiaxis and wheel shaft, conventional universal-joint is connected.But owing to being subject to the restriction of axial dimension, require drift angle larger again, the instantaneous angular velocity that single universal-joint can not make output shaft and axle enter axle equates, easily cause vibration, the damage of aggravation parts, and produce very large noise, so extensively adopt multi-form constant-velocity universal joint.On front drive automobile, two constant-velocity universal joints for each semiaxis, the universal-joint of close transaxle is inboard universal joint, near axletree is outboard universal joint.On rear drive automobile, driving engine, power-transfer clutch and change-speed box are as an integral installation on vehicle frame, and drive axle is connected with vehicle frame by resilient suspension, has a distance between the two, need to connect.In automotive operation, Uneven road produces and beats, the potential difference of load variations or two assembly installations etc., capital changes angle and the distance between transmission output shaft and main reducing gear of drive axle input shaft, therefore the universal-joint type of belt drive at rear drive automobile all adopts double jaw joint, be exactly that transmission shaft two ends respectively have a universal-joint, its effect is that the angle at transmission shaft two ends is equated, thereby guarantee that output shaft equates all the time with the instantaneous angular velocity of input shaft, and simple in structure, easily manufactured.
Summary of the invention
The object of the present invention is to provide a kind of automotive trannsmission system of reliable operation, have simple in structure, easily manufactured, reliable operation.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of automotive trannsmission system of reliable operation, comprise Universal drive module and driving circuit, described Universal drive module and described driving circuit are electrically connected, described Universal drive module comprises Hooke's coupling, transmission shaft and driving chain, described Hooke's coupling is marmem, and the free-sliding spline that described transmission shaft is comprised of with castellated shaft cliding yoke is connected.
In a preferred embodiment of the present invention, described marmem is omnidistance memory effect alloy.
In a preferred embodiment of the present invention, described driving circuit is servomotor.
In a preferred embodiment of the present invention, described driving chain is belt or steel rope.
The automotive trannsmission system of a kind of reliable operation of the present invention, have simple in structure, safe and practical, can the in the situation that of broken tire, adhere to travelling.
Accompanying drawing explanation
Fig. 1 is the automotive trannsmission system block diagram of reliable operation in a preferred embodiment of the present invention.
The specific embodiment
Below be only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of specification sheets, below with a preferred embodiment and accompanying drawing, technical scheme of the present invention is further described.
Consult Fig. 1, the automotive trannsmission system of this kind of reliable operation, comprise Universal drive module and driving circuit, described Universal drive module and described driving circuit are electrically connected, described Universal drive module comprises Hooke's coupling, transmission shaft and driving chain, described Hooke's coupling is marmem, and the free-sliding spline that described transmission shaft is comprised of with castellated shaft cliding yoke is connected.
In one embodiment, the automotive trannsmission system of a kind of reliable operation of the present invention, comprise Universal drive module and driving circuit, described Universal drive module and described driving circuit are electrically connected, described Universal drive module comprises Hooke's coupling, transmission shaft and driving chain, described Hooke's coupling is marmem, the free-sliding spline that described transmission shaft is comprised of with castellated shaft cliding yoke is connected, described marmem is omnidistance memory effect alloy, described driving circuit is servomotor, and described driving chain is belt or steel rope.
Principle of work: universal driving device is generally comprised of universal joint and drive shaft, also will have center support sometimes.In universal-joint coordinates, parts (output shaft) are around the rotary actuation of its axle by another parts universal-joint (input shaft) around the rotation of self axle.By universal-joint, on torsional direction, whether there is obvious elasticity can be divided into rigid cardan and flexible universal joint.Rigid cardan can be divided into again three kinds of nonconstant velocity universal joint (conventional for Cardon universal joint), near constant velocity universal joint (as dual cardan type U-joint) and constant-velocity universal joints (as Rzeppa joint).In vehicle traveling process, the relative position of change-speed box and drive axle often changes, and for avoiding movement interference, transmission shaft uses the free-sliding spline being comprised of with castellated shaft cliding yoke to be connected, to adapt to the variation of propeller shaft length.For reducing wear, lubrication adapter, oil sealing, blanking cover and the dust protecting cap of the consistent lubricant that is also equipped with to annotate.Transmission shaft is when High Rotation Speed, and the centnifugal force causing because quality is inhomogeneous will make transmission shaft generation strenuous vibration.Therefore after transmission shaft and universal-joint assembling, must carry out kinetic balance.The automotive trannsmission system of a kind of reliable operation of the present invention, simple in structure, easily manufactured, reliable operation.
The specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention, and the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
