Description
Technical field
The present invention relates to a kind of shaft drive buffer mechanism, particularly a kind of Motor Vehicle that is used for is as the shaft drive buffer mechanism of two-wheeled, three-wheel, four-wheel motor cycle, beach buggy.
Background technique
In the present shaft drive, its power input shaft and pto often are directly to assemble by universal joint, this direct assembly structure belongs to hard transmission (being positive drive) in power transmission process, because the change of transport velocity, particularly object is in the moment of quickening, and is quite big for the impact of shaft drive power source.Engine shaft transmission with motor vehicle is an example, their motor adopt mostly transmission shaft by and universal joint and rear-end gear reduction between rigidly connected structure, this being rigidly connected can be along with the change of vehicle drive operating mode, as speed-raising, gear shift or with jolting that Uneven road causes, all can produce a kind of alternating shock load, the recoil force that this alternating shock load forms can be delivered to the power input shaft of shaft drive, pass to the engine output shaft that directly assembles with it again, thereby to clutch, gearbox, universal joint, motor impacts, produce bigger noise, shortened clutch, gearbox, universal joint, the working life of motor, flame-out phenomenon also can appear sometimes, bring discomfort to driver and passenger, also can cause security incident when serious.
In order to reduce impact to power source, CN1188611C discloses a kind of " shaft drive buffer mechanism " that is used for engine shaft transmission gear reversing device, and it is to set up a damping mechanism as the engine output shaft of power input shaft and the power input shaft inner room as the shaft drive of pto.And less for 100ml～this mounting point of 200ml motorcycle engine, inconvenience is installed, and makes the manufacturing process difficulty of each component strengthen the occasion that this suitable dimensions structure is bigger.
Summary of the invention
The object of the present invention is to provide a kind of shaft drive buffer mechanism of making, installing be convenient to.
The object of the present invention is achieved like this: a kind of shaft drive buffer mechanism, it is characterized in that: driven off by shaft power input shaft and pto through outside be with stage clip the spline housing spline be connected, and R groove outside the front end of described pto is provided with, be somebody's turn to do the interior R groove coupling of outer R groove and described power input shaft, in inside and outside R groove, be provided with steel ball.
Above-mentioned power input shaft is an axle sleeve, and this axle sleeve is connected for the straight-tooth spline with described spline housing cylindrical, and the endoporus of described spline housing is connected for the helical tooth spline with described pto.
Above-mentioned axle sleeve has the steel ball mounting hole that communicates with described interior R groove outward.
One end of above-mentioned stage clip contacts with described axle sleeve exterior edge face, and the other end contacts with the axial step interior edge face that is arranged at described spline housing; The axial step exterior edge face of described spline housing contacts with the axial step interior edge face of described pto.
Above-mentioned spline housing is with spring seat outward, and this spring seat contacts with the axial step interior edge face of described spline housing, and stage clip is placed in outside the described spring seat, and the one end contacts with spring seat, and the other end of stage clip contacts with the exterior edge face of described power input shaft; The axial step exterior edge face of described spline housing contacts with the axial step interior edge face of described pto.Why the present invention sets up spring seat outside spline housing, mainly be to make in order on technology, to be convenient to, because desire is processed into the step surface with stage clip equal diameters with an end of spline housing, the technology difficulty of its processing external splines will be very big, for the ease of processing, reduce manufacture cost, at spline housing overcoat one spring seat, the preferred version of can yet be regarded as.
In addition, the above-mentioned spline housing that power input shaft is connected with pto, the form of external splines is disposable in it, and it also can be that the cylindrical of spline housing is connected with power input shaft helical tooth spline, and the endoporus of spline housing is connected for the straight-tooth spline with pto.
When this damping mechanism is installed on the splined shaft of engine shaft transmission gear reversing device, one end of this splined shaft is the power input shaft of axle sleeve as damping mechanism, and the output shaft that links to each other through spline housing is connected with rear-end gear reduction as the pto of damping mechanism with it; Be provided with pin in the steel ball mounting hole of on the axle sleeve of described splined shaft, opening, the axle sleeve of described splined shaft outer through bearing fixing in casing, output shaft, and is sealed by case lid in casing through bearing fixing.
As everyone knows, in shaft drive,, all be rigidly connected without exception because power input shaft and pto pass to back axle or propons by universal joint with moment of torsion.So need set up a mechanism to reach the purpose of buffering at two between centers.In the present invention, spline housing is a core members, for it is internal spiral tooth (dextrorotation or left-handed), outer straight-tooth spline or interior straight-tooth, external spiral tooth spline (dextrorotation or left-handed), can determine according to the particular location that this damping mechanism is arranged on shaft drive, in a word, the form of external splines in the spline housing, it mainly is the Economy made from the counteracting and the technology of solution axial force, axial force should be offset on the transmission shaft of shaft drive and to determine, as long as the energy head it off, the form of the interior external splines of spline housing is all in the present invention's scope required for protection; In the present invention, also have a critical component to be provided with steel ball exactly, this ingenious design of the present invention, axially locating and radial centering that the end that guaranteed pto in limited bulk and splined shaft also are power input shaft have been solved, form a rolling bearing bigger by steel ball and inside and outside R groove than deep groove ball bearing axial rigidity, be enough to offset the axial force of stage clip, thereby reached splined shaft and the counterrotating purpose of output shaft.In a word, the present invention is installed between the splined shaft and output shaft of shaft drive gear reversing device, and is not only easy to make, is convenient to install, and can also reach the purpose of buffering effectively.
The present invention is further illustrated below in conjunction with description of drawings and most preferred embodiment.
