Description
Technical field
The present invention relates to steering system technical field, in particular to a kind of tripod diverter.
Background technique
Diverter is very important critical component in wheel steering system, and principle is that driver turn steering wheel drives
The rotary motion of steering wheel is changed into axial movement by internal gear by steering shaft and diverter, and the performance of diverter will be straight
Connect the stability and reliability for influencing Vehicular turn.
Existing diverter is slid axially from the optical axis with rack gear and completion with bearing inner race, due to light
Axis and bearing inner race are sliding frictions, for a long time using the abrasion that can aggravate between optical axis and bearing, cause to turn to abnormal sound influence
It drives quality and increases maintenance cost.
Summary of the invention
The present invention is to provide a kind of tripod diverter to overcome above-mentioned defect in the prior art, sliding with tradition
Shifting formula diverter is compared, and axial movement mode is become rolling from sliding, the frictional force of axial movement is greatly reduced, improves
The service life of product.
To achieve the above object, the present invention provides a kind of tripod diverter, including shell and setting are inside the shell
Axial rolling device, there is in the shell slid chamber, in the outer rim of the slid chamber tool there are three with axial parallel guiding
Slot；
The axial rolling device includes connecting shaft and three ball pins for being connected to connecting shaft both ends, which includes spider
And rolling assembly, the rolling assembly are three groups and are spindle rotationally arranged on three pin shafts of spider respectively；
The axial rolling device is mounted in slid chamber, and rolling assembly described in three groups is embedded in three guide grooves respectively and energy
It is enough to be rolled each along guide groove is axially sliding.
It is further arranged to: equipped with the housing matched with its size, shape, three column in the slid chamber of the shell
Pot shell has track corresponding with three guide grooves.
Be further arranged to: the housing is made of metal material and through Overheating Treatment cure process.
It is further arranged to: two sides that three tracks of the housing are arranged in non-equal part and the track is opposite
Wall surface is arc surface.
Be further arranged to: the rolling assembly includes ball and needle roller, which is socketed on the pin shaft of spider, should
Needle roller is arranged between ball and pin shaft.
Compared with prior art, the configuration of the present invention is simple, rationally, compared with the sliding diverter of tradition, will move axially
Mode becomes rolling from sliding, and greatly reduces the frictional force of axial movement, improves the service life of product.

Specific embodiment
With reference to the accompanying drawing, the specific embodiment of the present invention is described in detail, it is to be understood that of the invention
Protection scope be not limited by the specific implementation.
One kind of the invention three ball pins, 22 formula diverter is as shown in Figure 1 to Figure 3, including shell 1 and setting are in shell 1
Axial rolling device 2, which has by metal material integrally casting shaping, in the shell 1 for installing axial rolling dress
2 slid chamber is set, there are three the guide grooves 11 that axis is arranged and be parallel in non-equal part for tool on the outer edge surface of the slid chamber；The axis
Include connecting shaft 21 to tourelle 2 and be connected to three ball pins 22 at 21 both ends of connecting shaft, the ball pin include spider 221,
And it is rotatably provided in the rolling assembly on three pin shafts 2211 of spider 221 respectively, rolling assembly preferably includes ball
222, needle roller 223, retaining ring 224 and circlip 225, there are three the ball 222 tools and is socketed in three pin shafts of spider 221 respectively
On 2211, which is arranged between ball 222 and pin shaft 2211 so that ball 222 and pin shaft 2211 are in rolling cooperation,
Frictional force between the two is greatly reduced, the retainer ring and circlip 225 are arranged at the outside on pin shaft 2211 and being located at ball 222
Locking ball 222 on pin shaft 2211；The axial rolling device 2 is mounted in slid chamber, corresponding, and three of three ball pins 22
And ball 222 interior embedded in three guide grooves 11 can be along the axial sliding rolling of guide groove 11 respectively for ball 222.
Preferably, housing 3 compatible with slid chamber size, shape, three column are equipped in the slid chamber of shell 1
Pot shell 3 has track 31 corresponding with three guide grooves 11, and the ball 222 of three ball pins 22 is arranged in track 31；Preferably,
The housing 3 is made of metal material and by heat treatment cure process, so that housing 3 has high-intensitive and height
Wearability；Preferably, the two sides that three tracks 31 of housing 3 are arranged in non-equal part and track 31 is opposite are arc surface knot
Structure, so that the arc surface of the spherical outside surface of ball 222 and housing 3 being capable of automatic aligning.
Compared with prior art, the configuration of the present invention is simple, rationally, compared with the sliding diverter of tradition, will move axially
Mode becomes rolling from sliding, and greatly reduces the frictional force of axial movement, improves the service life of product.
Disclosed above is only the embodiment of the present invention, and still, the present invention is not limited to this, the technology of any this field
What personnel can think variation should all fall into protection scope of the present invention.
