Description
Technical field
This utility model relates to technical field of automobile, is specially a kind of automobile dipentodon sinicus key axle.
Background technology
Dipentodon sinicus key axle is that machine driving is a kind of, the same with flat key, woodruff key, taper key effect, is all to pass
Passing mechanical torque, the appearance at axle has longitudinal keyway, and the revolving part being enclosed within axle also has the key of correspondence
Groove, can keep with axle synchronous rotary, and while rotating, have can also make longitudinal sliding motion on axle,
Such as gearbox gear-shift gear etc..
Splined shaft is applied in brake, steering mechanism.Also having one is telescopic axle, is made up of inner and outer pipes,
Outer tube has internal tooth, inner tube to have external tooth, is nested together.During use while transmission rotation torque, growing
Can stretch in degree direction.
The key tooth skewness of existing dipentodon sinicus key axle, is susceptible to root and cuts, thus affect whole automobile
Working effect, for this it is proposed that a kind of automobile dipentodon sinicus key axle.
Utility model content
The purpose of this utility model is to provide a kind of automobile dipentodon sinicus key axle, to solve above-mentioned background skill
The problem proposed in art.
For achieving the above object, the following technical scheme of this utility model offer: a kind of automobile dipentodon sinicus key
Axle, including hub splines body, the left side of described hub splines body is provided with end cap, described spline
The inner chamber of sleeve body has wedge-shaped slot, and the right side of described hub splines body connects connecting shaft, described
The right side inner chamber of connecting shaft has polygon sleeve, and the right side of described connecting shaft is provided with male splined shaft, institute
The surface configuration stating male splined shaft has external spline teeth.
Preferably, the top of described hub splines body has tank filler sleeve.
Preferably, the number of teeth of described external spline teeth is ten, and is evenly distributed on the surface of male splined shaft.
Preferably, the left side of described male splined shaft is provided with the polygon matched with polygon sleeve and is connected
Bar.
Compared with prior art, the beneficial effects of the utility model are: this utility model discloses a kind of vapour
Automobile-used dipentodon sinicus key axle, is a kind of cylindrical straight gear involute outer spline axle, and the number of teeth is 10, flower outside involute
Key uses forging technology one-shot forming, and tooth can be made to be uniformly distributed, spline uniform force in use, with
Time improve machining accuracy and assembly precision, this utility model spline tooth is shorter, and tooth root is wider, be difficult to send out
Take root and cut；Root portion intensity is high, and stress collection is medium and small, it is easy to centering so that whole axle has bigger torsion
Square.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；

In figure: 1 hub splines body, 2 connecting shafts, 3 male splined shafts, 4 external spline teeth, 5 polygon sets
Cylinder, 6 wedge-shaped slots, 7 end caps.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment
Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one
Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common
The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this
The scope of utility model protection.
Referring to Fig. 1-2, this utility model provides a kind of technical scheme: a kind of automobile dipentodon sinicus key axle,
Including hub splines body 1, the left side of described hub splines body 1 is provided with end cap 7, described spline
The inner chamber of sleeve body 1 has wedge-shaped slot 6, and the right side of described hub splines body 1 connects connecting shaft 2,
The right side inner chamber of described connecting shaft 2 has polygon sleeve 5, and the right side of described connecting shaft 2 is provided with outer flower
Key axle 3, the surface configuration of described male splined shaft 3 has external spline teeth 4.
Wherein, the top of described hub splines body 1 has tank filler sleeve, convenient to hub splines body 1
Inner chamber increase lubricating oil, make whole device the most flexible, the number of teeth of described external spline teeth 4
It is ten, and is evenly distributed on the surface of male splined shaft 3, spline uniform force during use, improve simultaneously
Machining accuracy and assembly precision, the left side of described male splined shaft 3 is provided with and polygon sleeve 5 phase
The polygon connecting rod joined, conveniently dismantles and is connected.
Operationally, ten tooth tooth roots on male splined shaft 3 are wider, and dedendum strength is high, and stress is concentrated,
Ensure that the precision of assembling, improve the service life of splined shaft.
Embodiment the most of the present utility model, for the ordinary skill people of this area
For Yuan, it is possible to understand that can be real to these in the case of without departing from principle of the present utility model and spirit
Executing example to carry out multiple change, revise, replace and modification, scope of the present utility model is by claims
And equivalent limits.
