Description
Technical field
It the utility model is related to automobile synchronizer cross axle.
Background technology
Automobile synchronizer cross axle-inter-axle differential is one of important spare part in automobile variable speed mechanism on drive axle,
Its crudy, structure, service life etc. directly influence normally travel and the personal safety of driver and crew of automobile.Due to
Case hardness is relatively low, and corrosion resistance of surface is poor, in the use of reality due to big load, road conditions condition is poor, insufficient lubrication when it is easy
There is cross axle abrasion and ablation, be even sintered into one when serious with planetary gear, in heavy-duty car, inter-axle differential ten
Word axle is particularly easy to produce such failure.
The content of the invention
The utility model provides automobile synchronizer cross axle, and it not only increases the hardness of the damageable zone of cross axle,
And prevent from being broken when heavy load runs at high speed, improve the fatigue limit of body.
The utility model employs following technical scheme：Automobile synchronizer cross axle, it includes cross shaft body, in cross
The centre of shaft body is provided with inner ring, is provided with internal spline on the surface of inner ring, the input shaft of connecting intermediate axle, jackshaft are installed with inner ring
Input shaft be connected by internal spline with cross shaft body, be evenly distributed with some connecting poles in the outer surface of cross shaft body,
One end of each connecting pole is connected with cross axle body surface, and the other end of each connecting pole is connected with planetary gear, in connecting pole
Combined between cross shaft body provided with arc-shaped transition.
Described cross shaft body is 20CrMnTiH structural alloy steels.Described connecting pole is cylinder.Described
20CrMnTiH structural alloy steels are the 20CrMnTiH structural alloy steels by phosphorating treatment and carburizing and quenching.Described arc mistake
Crossing combination includes arc-shaped transition I and arc-shaped transition II, arc-shaped transition I be located at connecting pole and cross axle body surface plane it
Between, arc-shaped transition II is located between the plane of cross axle body surface and the arcwall face of cross shaft body.
The utility model has the advantages that：After employing above technical scheme, surface of the present utility model uses
Phosphorating treatment so that the surface corrosion resistance of cross axle can improve, so as to improve its service life.Set among the utility model
There is internal spline, internal spline is used for connecting intermediate axle input shaft, receives the moment of torsion that input direction transmits, there are four on body into cross
The outside cylinder of shape, outside cylinder are used to connect four planetary gears, and arc-shaped transition combination includes arc-shaped transition I and arc-shaped transition II, arc
Shape transition I is located between connecting pole and the plane of cross axle body surface, and arc-shaped transition II is located at the flat of cross axle body surface
Between the arcwall face of face and cross shaft body, so prevent from being broken when automobile high-speed from operating, surface uses phosphorating treatment, carries
The corrosion resistance of high cross axle.The utility model not only increases the hardness of the damageable zone of cross axle, and prevents in weight
It is broken when load runs at high speed, improves the fatigue limit of body.
