Dynamic mechanism, effect is to meet vehicular transmission shaft outer end corner power of engine is delivered from speed changer to automotive wheels
It is required that.
Existing constant velocity driving shaft includes mounted on the first universal joint of road wheel end, jackshaft and mounted on gearbox end
Second universal joint, jackshaft both ends are connected with the first universal joint and the second universal joint respectively；First universal joint is in order to adapt to vehicle
It takes turns corner to need, generally axially fixed spherical rotational structure；Second universal joint is generally for the axis for adapting to constant velocity driving shaft
Change to length, is set as three pin nodal patterns that can be axially extending.
Three pin nodal pattern universal joints include shell and lubrication groove, and shell is set there are three the idler wheel alley around axially spaced-apart setting,
Idler wheel alley axially extends to the port of shell along the shell；Lubrication groove is equipped with axis hole in an axial direction, and the jackshaft is socketed on axis
Kong Zhong, interior wheel outer surface, which is surround, is axially arranged with three three axis pins radially extended, three axis pins and three idler wheel alley phases
It is corresponding, idler wheel is socketed on each three axis pin, idler wheel is embedded in idler wheel alley；The outer surface of idler wheel is arc-shaped, and is rolled
Take turns the constraint of the two sides of alley so that rolling is moved along idler wheel alley.
The shortcomings that existing structure, is：Oscillating function is carried out around three axis pins in order to make idler wheel have, so that lubrication groove is covered
The jackshaft connect is axially formed angle with shell, and the surface of three axis pins is set as spherical surface, and the axis hole of idler wheel is set as corresponding
Arc surface, the socket of spherical surface and arc surface, is caused difficult to install described in the installation process of idler wheel and three axis pins；In addition, rolling
The suffered power of wheel is from the side surface of idler wheel alley, this power passes to three axis pins by idler wheel, and the stress point of three axis pins is face
The both side surface position of way roller alley side surface, and three axis pins are in the surface portion stress very little of lubrication groove axial direction, do not have
It is necessary to keep spherical surface, it is unfavorable for Weight control and the installation of three axis pins.
Utility model content
The utility model be in order to overcome above-mentioned defect in the prior art, by by three axis pins interior wheel shaft to surface element
Face is evaded in setting, both mitigates weight, when mounted due to without the constraint for evading facial plane so that idler wheel and three axis pins
Socket installation is greatly easy.
To achieve the above object, the utility model provide one kind three sell nodal pattern constant velocity driving shaft, including the first universal joint, in
Countershaft and the second universal joint mounted on gearbox end, jackshaft both ends are connected with the first universal joint and the second universal joint respectively
It connects, the second universal joint is three pin nodal patterns, and three pin nodal pattern universal joints include shell and lubrication groove, and shell sets that there are three around axially spaced-apart
The idler wheel alley of setting, idler wheel alley axially extend to the port of shell along the shell；Interior wheel outer surface, which is surround, to be axially arranged with
Three three axis pins radially extended, three axis pins are corresponding with three idler wheel alleys, and idler wheel is socketed on each three axis pin, rolling
Wheel is in idler wheel alley；Wherein, the surface of three axis pins socket idler wheel is spherical shape, and the shaft bore surface that idler wheel is socketed three axis pins is
Corresponding arc-shaped, three axis pin surfaces are equipped at the axial direction position of lubrication groove evades face, and it is that plane or radius are more than to evade face
Three axis pins are socketed the spherical radius of idler wheel so that the weight saving of lubrication groove, and reduce rubbing when being rotated between three axis pins and idler wheel
Wiping face is swung when three axis pins also being allow to be socketed on roller shaft hole on the axial direction of lubrication groove, convenient for socket operation, is reduced
The difficulty of installation.
Preferably, evade and be equipped with transition circle cambered surface between face and the end face of three axis pins so that idler wheel is when being socketed three axis pins
It can smoothly be inserted in three axis pins along transition circle cambered surface.
Three axis pins are designed with upwards in interior wheel shaft evades face so that the weight saving of three axis pins, installation are more square
Just.
Compared with prior art, the utility model by by three axis pins interior wheel shaft to surface element setting evade face, both
Mitigate weight, when mounted due to the constraint without end face so that the socket installation of idler wheel and three axis pins is greatly easy, idler wheel
Rub smaller when swinging work；By evading between face and the end face of three axis pins equipped with transition circle cambered surface so that idler wheel is covering
It connects more smooth when three axis pins, but also three axis pins and idler wheel keep preferably cooperation, reduces by the vibrations of three pin sections, noise and not
Ride comfort improves the working life of three pin sections.
