The utility model discloses an it is individual that spline quantity is the odd number, forms unsymmetrical structure, during with broach processing spline, does not need the frock clamp location, only fixes a position with the semicircle at universal cross earhole top, and it is very convenient to process.
Description
Technical field
This utility model relates to technical field of automobile components, particularly to a kind of propeller shaft slip spline fork.
Background technology
In use, its power transmission shaft is one of parts being easy to abrasion and damage to vehicle, especially vehicle
In running at high speed, the free-sliding spline fork of power transmission shaft raises with slip shaft yoke temperature, abrasion aggravation so that slide
Spline fork is easy to damage, and free-sliding spline fork needs again by forging processing, heat treatment, machine with slip shaft yoke
The complicated technologies such as tool processing complete, relatively costly, cause the wasting of resources, and cost of use increases.
The reason mainly spline that free-sliding spline fork is easy to damage uses square key, between square key radial direction
Gap is big, and torsion is poor, is assembled by main engine plants, and dynamic balancing is unstable, and power transmission shaft is easily sent out shake, mainly showed themselves in that
Stress at the bottom of square key key, two side clearances are big, the most wear-resisting, are difficult to processing, and maintenance cost is high, original equipment manufacturer
Quality is unsatisfied with by side and client.
Further, the quantity of present spline is even number, during processing, is to enter with the position of spline
The processing of row location, location inconvenience, difficulty of processing is bigger.
Utility model content
This utility model provides a kind of propeller shaft slip spline fork, solves existing propeller shaft slip spline fork and adds
The problem processing inconvenience during work.
For solving above-mentioned technical problem, the technical solution of the utility model is:
A kind of propeller shaft slip spline fork, including the fixing universal-joint fork connected and slip cap, described universal joint
Fork is provided with on left fork ear and right fork ear, described left fork ear and described right fork ear and is respectively arranged with coaxial cross
Axle installing hole, arranges involute spline in described slip cap, the quantity of described involute spline is odd number.
Wherein it is preferred to, 17 of the quantity of described involute spline, 19 or 21.
Wherein it is preferred to, described involute spline surface configuration matcoveredn.
Wherein it is preferred to, the pressure angle of described involute spline is 25～35 °.
Wherein it is preferred to, the pressure angle of described involute spline is 30 °.
The beneficial effects of the utility model:
1. the spline quantity of this utility model propeller shaft slip spline fork is odd number, forms dissymmetrical structure, uses
During broaching tool processing spline, it is not necessary to frock clamp positions, and only enters with the semi arch at universal cross earhole top
Row location, processes very convenient, and when spline quantity is even number, carrying out broaching machine processing with broaching tool have to
Position with special frock clamp.
2. rectangular teeth spline is made into large pressure angle involute short tooth spline by this utility model, and involute telescopic fork is joined
Conjunction gap is little, both sides stress, and radial clearance is little, power transmission shaft dynamic balance stability, durable, decreases power transmission shaft
Maintenance frequency and cost of upkeep, the most not only add intensity but also be easy to extrusion molding, adapt to big torque operating mode
Needs.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real
Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people
All other embodiments that member is obtained under not making creative work premise, broadly fall into this utility model
The scope of protection.
As shown in FIG. 1 to 3, the present embodiment provides a kind of propeller shaft slip spline fork, including fixing connection
Universal-joint fork 1 and slip cap 2, universal-joint fork 1 is provided with left fork ear 1-1 and right fork ear 1-2, left fork ear 1-1
Be respectively arranged with coaxial cross axle installing hole 1-3 on right fork ear 1-2, arrange in slip cap 2 involute flower
Key 3, the quantity of involute spline 3 is odd number.Spline quantity is 19, forms dissymmetrical structure, uses
During broaching tool processing spline (positioning fixture 5 is as shown in Figure 3), it is not necessary to frock clamp positions, only with universal ten
The semi arch at cabinet frame earhole top positions, and processes very convenient.It addition, by common rectangular teeth spline
Making large pressure angle involute short tooth spline into, involute telescopic fork fit clearance is little, both sides stress, between radial direction
Gap is little, power transmission shaft dynamic balance stability, durable, decreases maintenance frequency and the cost of upkeep of power transmission shaft, so
Not only add intensity but also be easy to extrusion molding, adapt to the needs of big torque operating mode.
In this utility model, the quantity of spline is generally alternatively 17 or 21.
Wherein, involute spline 3 surface configuration matcoveredn 4, protective layer 4 can use nylon, this spline structure
Propeller shaft slip fork have wear-resisting, the feature of length in service life.
Wherein, the pressure angle of involute spline 3 is 30 °, and the modulus of the present embodiment involute spline 3 is 2.5.
The large pressure angle involute short tooth spline of the present embodiment, involute telescopic fork fit clearance is little, both sides stress,
Radial clearance is little, power transmission shaft dynamic balance stability, durable, decreases maintenance frequency and the cost of upkeep of power transmission shaft.
In this utility model, the pressure angle of involute can be 25～35 °.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
