Abstract
The utility model relates to a shaft driven cushioning device, which is characterized in that a cushioning device is added between a power input axis and a power output axis. The cushioning device comprises an inner sleeve (2), a jacket and a compression spring (3). Wherein, the power input axis is arranged inside the inner sleeve (2) of the cushioning device, the excircle of the inner sleeve (2) is connected with the jacket of the power output axis via a screwing key, and a compression spring (3) is arranged at the axial end-face of the inner sleeve (2). The utility model can remove during the process of high-frequency vibration power transmission, which truly realizes flexible connection of the torque transmission of the shaft driving with a cushioning function.
Description
Technical field
The utility model relates to a kind of shaft drive buffer mechanism, particularly a kind ofly is applicable to all kinds of motor bikes, as the driving engine shaft drive buffer mechanism of two-wheeled, three-wheel, four-wheel motor cycle, atv motorcycle.
Background technology
In the present shaft drive, its power input shaft and power take-off shaft often are direct assemblings, thisly directly be assemblied in the power transmission process, impact for the shaft drive propulsion source is quite big, engine shaft transmission with power actuated vehicle is an example, such as three-wheel, motor bike and beach buggy more than the three-wheel, their engine output shaft great majority adopt shaft drives to be connected with rear-axle differential.ZL98228725.9 discloses " a kind of trail bike driving engine reverse gear ", it is that engine output shaft is directly assembled initiatively spline conical gear, the active spline conical gear of engine output shaft assembling directly and two castellated no key conical gears that assemble on another castellated shaft mesh the location simultaneously, and on the castellated shaft between two castellated no key conical gears, installation can with any castellated bidirectional clutch of unidirectional chimeric spline of two castellated no key conical gears, and castellated shaft connects with the rear-axle differential castellated shaft through transmission shaft component simultaneously.The shaft drive of this driving engine, because its power take-off shaft and rear-axle differential are a kind of being rigidly connected, this being rigidly connected can be along with the change of vehicular drive working condition, as speed-raising, gear shift or jolt with ground-surface, produce a kind of alternating shock load, the recoil that this alternating shock load forms can be delivered to the power intake of shaft drive, pass to the engine output shaft that directly assembles with it again, thereby driving engine is impacted, produce bigger noise, influence the service life of driving engine, also occur flame-out phenomenon sometimes, and give the numbness sensation of a kind of discomfort of driver and crew.
Summary of the invention
The purpose of this utility model is to provide a kind of shaft drive buffer mechanism.
The utility model is achieved in that a kind of shaft drive buffer mechanism, it is characterized in that: set up buffer gear at power input shaft and takeoff output between centers; Buffer gear comprises interior cover, overcoat and stage clip, and wherein power input shaft is assemblied in the interior cover of buffer gear, and interior cover cylindrical is connected for the helical tooth spline with overcoat as power take-off shaft, is provided with stage clip between the axial end of interior cover and overcoat inner end surface.
Wearing and tearing for cover end face in reducing are provided with packing ring between above-mentioned interior cover and above-mentioned stage clip.
The utility model has been installed buffer gear at power input shaft and takeoff output between centers, cover was made axial motion along the outer spiral spline pair in the power input shaft rotation drove, compression press spring can eliminate producing high and low frequency resonance in the power transmission process, plays buffer action.This is because the interior cover of buffer gear is connected for the helical tooth spline with overcoat as power take-off shaft, so when the working condition in the power transmission process changes, the alternating shock load that produces changes the powerful recoil that forms, can be because interior cover and the axial stage clip that is provided with thereof, make power input shaft, interior cover, power take-off shaft have the torque characteristics of gantry hysteresis each other, absorb part energy, thereby reach the purpose of buffering, reduced impact to propulsion source, reduce noise and vibration simultaneously, prolonged the service life of driving engine and shaft drive.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
The structural representation of Fig. 1, the utility model embodiment;
Fig. 2, be the A-A cutaway view of Fig. 1.
The specific embodiment
A kind of shaft drive buffer mechanism is characterized in that: set up buffer gear at power input shaft and takeoff output between centers; Cover 2, overcoat and stage clip 3 in buffer gear comprises, wherein power input shaft is assemblied in the interior cover 2 of buffer gear, and interior cover 2 cylindricals are connected for the helical tooth spline with overcoat as power take-off shaft, are provided with stage clip 3 between the axial end of interior cover 2 and overcoat inner end surface.
Referring to above-mentioned accompanying drawing as can be known: when the utility model is used for motor cycle engine shaft drive gear reversing device, described buffer gear is assemblied between the power input shaft cover 1 of engine output shaft 4 and shaft drive, engine output shaft 4 wherein is as power input shaft, and the power input shaft of shaft drive cover 1 is a power take-off shaft; Also be that engine output shaft 4 is assemblied in the interior cover 2 of buffer gear, for rectangular spline connects, in cover 2 cylindricals be connected for the helical tooth spline with the overcoat that overlaps 1 as the power input shaft of shaft drive, between the axial end of interior cover 2 and overcoat inner end surface, be provided with stage clip 3.In this example, the power input shaft of shaft drive cover 1 inner spline housing of the gear reversing device driving tooth among the figure just.
It can also be seen that from accompanying drawing: 3 of interior cover 2 and stage clips are provided with packing ring 5.
Claims (4)
1, a kind of shaft drive buffer mechanism is characterized in that: set up buffer gear at power input shaft and takeoff output between centers; Buffer gear comprises interior cover (2), overcoat and stage clip (3), wherein power input shaft is assemblied in the interior cover (2) of buffer gear, in cover (2) cylindrical be connected for the helical tooth spline with overcoat as power take-off shaft, between the axial end of interior cover (2) and overcoat inner end surface, be provided with stage clip (3).
2, shaft drive buffer mechanism as claimed in claim 1, it is characterized in that: described buffer gear is assemblied between the power input shaft cover (1) of engine output shaft (4) and shaft drive, engine output shaft wherein (4) is as power input shaft, and the power input shaft cover (1) of shaft drive is a power take-off shaft.
