Description
Technical field
The invention belongs to automobile steering system production equipment technology, and in particular to a kind of wheel steering system high density
Tooth jackshaft production line.
Background technology
The public axis of existing jackshaft and the connection mode of mother's axle mainly have two major classes：Lock fixed pattern and key slidingtype.Wherein,
Key slidingtype is that external splines is processed on public axis, and matched internal spline is processed in mother's axle, and then the external splines of public axis is carried out
Injection molding and form an injection molded layers, after the completion of public axis is pressed into mother's axle.This jackshaft male and female axis connection mode it is excellent
Point is that public axis and mother's axle opposite can slide certain distance, so as to play the role of damping noise reduction, still, due to Shooting Technique
Limitation, has strict requirements to the number of teeth of external splines, is usually no more than 10 teeth, otherwise injection molded layers can fill slot, make public axis
It can not be assembled with mother's axle, therefore the jackshaft of this low-density tooth has the defects of rigidity is low, stiffness degradation is big, it is impossible to hold
By large torque, maximum bears torque demand and is less than 50Nm, thus can not be applied on the oversize vehicles such as SUV.Born to overcome
The defects of moment of torsion is small, has individual manufacturer flower great cost to continuously improve Shooting Technique, is but only capable of obtaining extremely limited effect,
Make the external splines of public axis can at most process 24 teeth, but to be but still far unable to reach SUV etc. large-scale for the peak torque that can be born
80Nm~90Nm that vehicle usually requires that.
And lock fixed pattern is then that public axis first is pressed into mother's axle, can so be processed on public axis more than 40 teeth intensive outer
Spline, is then molded several plastic pins by Shooting Technique in mother's axle, in the public axis of these plastic pins insertion, locks male axis and mother
The relative position of axis.The advantages of this jackshaft male and female axis connection mode is the moment of torsion that can not only meet the oversize vehicles such as SUV
It is required that and relative inexpensiveness, still, due to public axis and mother's axle can not the opposite stress concentration slided, produced to wheel system,
In the presence of the problems such as vibrations are big, noise is big.
Therefore, we have developed a kind of high density tooth jackshaft, have two kinds of jackshafts of lock fixed pattern and key slidingtype concurrently
