Abstract
The utility model provides a junction structure of a transmission input shaft and a clutch hub for a car, which belongs to the technical field of machinery. The junction structure solves the problem that a spline has big possibility of generating plastic deformation as the spline gear side of the traditional junction structure is in clearance fit. The junction structure of the transmission input shaft and the clutch hub for the car is characterized in that the inner side of the clutch hub is provided with an inner spline; the outer side of the input shaft is provided with an outer spline; the input shaft is connected with the clutch by the inner spline and the outer spline; and each rack of the inner spline and the rack of the corresponding outer spline are inclined. In the junction structure, an involute spline with the inclined racks is adopted for cooperation to reduce the tooth alignment error when the spine is meshed, so that load distributed on each tooth is more uniform, impact noise between splines is recuced, and the service life of the input shaft is prolonged.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to the connecting structure of a kind of transmission input shaft and clutch hub, particularly a kind of car connecting structure of transmission input shaft and clutch hub.
Background technique
One end of the transmission input shaft on the automobile connects motor, power enters speed changer from motor through input shaft, the input gear that is driven on the axle by input shaft is given transmission of power output gear and is driven the output shaft rotation again, and drives the differential mechanism motion, and automobile just can advance or retreat.
At present, saloon car transmission input shaft and clutch hub connection are generally the straight-tooth involute splines and connect, and the spline flank of this connecting structure is a Spielpassung.Under actual conditions,, therefore can produce certain impact noise because there is certain clearance in flank.In addition, certain torsional deflection can take place in input shaft, thereby tooth alignment error is increased, and reduces the stationarity of transmitting torque, under impulsive load, makes spline produce plastic deformation easily, reduces working life.
Summary of the invention
The purpose of this utility model is at existing technology, has proposed a kind of low noise, the transmission input shaft in high working life and the connecting structure of clutch hub.
The purpose of this utility model can realize by following technical proposal: a kind of car connecting structure of transmission input shaft and clutch hub, described clutch hub inboard has internal spline, the described input shaft outside has external splines, and input shaft is connected by inside and outside spline with clutch hub, it is characterized in that, each tooth bar of described internal spline all with the tooth bar of corresponding external splines tilt.
Cooperate with the involute splines that the internal spline of clutch hub inboard adopts tooth bar to tilt with the transmission input shaft external splines, when speed changer is worked, input shaft can produce certain torsional deflection, and the interior external splines that designed tooth bar tilts to cooperate just in time reduces or offset the torsional deflection that input shaft produces, therefore the spline working surface is fitted more closely, can reduce noise and improve working life.
In the connecting structure of above-mentioned car with transmission input shaft and clutch hub, the tooth bar of described internal spline is along its axial setting, and the tooth bar of described external splines and input shaft shaft axis tilt.The tooth bar of the external splines of input shaft is obliquely installed and female splined shaft to setting, reduced the tooth alignment error that spline is produced when work, make load distribution even.
In the connecting structure of above-mentioned car with transmission input shaft and clutch hub, angle α is the 3-15 degree between described external splines tooth bar and the input shaft shaft axis.At external spline teeth bar and input shaft shaft axis angle is in the scope of 3-15 degree, and external splines can both effectively cooperate with internal spline, reduces the torsional deflection that input shaft produces.
In the connecting structure of above-mentioned car with transmission input shaft and clutch hub, angle α is 4 degree between described external splines tooth bar and the input shaft shaft axis.Angle is 4 when spending between external spline teeth bar and input shaft shaft axis, and the tooth bar between the spline cooperates best, and noise is minimum.
As another scheme, in the connecting structure of above-mentioned car with transmission input shaft and clutch hub, the tooth bar of described external splines is along its axial setting, and the tooth bar of described internal spline and clutch hub shaft axis tilt.
In the connecting structure of above-mentioned car with transmission input shaft and clutch hub, angle β is 5 degree between described internal spline tooth bar and the clutch hub shaft axis.Angle is 5 when spending between internal spline tooth bar and clutch hub shaft axis, and the tooth bar between the spline cooperates best, and noise is minimum.
Compared with prior art, this car has the following advantages with the connecting structure of transmission input shaft and clutch hub:
1. the tooth alignment error when having reduced spline engagement makes the load that is assigned on each tooth more even, reduces the impact noise between spline, improves input shaft working life.
2. this is simple in structure, processing technology is ripe, productivity is high.
