Abstract
The invention provides a high-speed high-bearing hub bearing unit, and mainly solves the problem that the existing hub bearing unit is not suitable for high-speed high-bearing hub bearings. The high-speed high-bearing hub bearing unit is characterized in that a first raceway and a second raceway are formed between one end of an outer flange plate and an inner flange plate, a third raceway and a fourth raceway are formed between the other end of the outer flange plate and a half inner ring, holders are arranged in the first raceway, the second raceway, the third raceway and the fourth raceway and are internally provided with roll balls, an included angle a between an axis connection line of the sections of the first raceway and the second raceway and the horizontal line is larger than 0 degree and smaller than 90 degrees, and an included angle a between an axis connection line of the sections of the third raceway and the fourth raceway and the horizontal line is larger than 0 degree and smaller than 90 degrees. According to the high-speed high-bearing hub bearing unit, the holders are arranged in the first raceway, the second raceway, the third raceway and the fourth raceway and are internally provided with the roll balls, the roll balls can work in a ball bearing manner on one hand, and two roll balls rotate like a needle bearing on the other hand; the hub bearing unit has the advantages of simple structure, high speed and high bearing performance.
Description
Technical field
The invention belongs to auto parts and components field, particularly a kind of hub-bearing unit of high speed high-mechanic.
Background technique
hub bearing, as the important component of automobile, plays transmitting torque and supports the effect of car body.Existing hub-bearing unit is roughly divided into two kinds, a kind of is the ball bearing of the low carrying of high speed, and another kind is the needle bearing of low speed high-mechanic, however to high speed high-mechanic hub bearing be but suitable for.
Summary of the invention
In order to overcome the deficiency of background technique, the invention provides a kind of hub-bearing unit of high speed high-mechanic, mainly solve existing hub-bearing unit and be roughly divided into two kinds, a kind of is the ball bearing of the low carrying of high speed, another kind is the needle bearing of low speed high-mechanic, however to high speed high-mechanic hub bearing but be not suitable for problem.
The technical solution adopted in the present invention is:
A kind of hub-bearing unit of high speed high-mechanic, comprise outward flange dish and inner flange, described inner flange secure fit has half inner ring, the first raceway and the second raceway is formed between described outward flange dish one end and inner flange, the 3rd raceway and the 4th raceway is formed between the other end and described half inner ring, described first, two, retainer is equipped with in three and four raceways, spin is provided with in described retainer, described first, the angle a formed between two groove-section axial connecting lines and horizontal line is greater than 0 ° and is less than 90 °, described 3rd, the angle a formed between four groove-section axial connecting lines and horizontal line is greater than 0 ° and is less than 90 °.
Seal ring is provided with between described outward flange dish and inner flange.
Described seal ring is lip-type packing.
On described outward flange dish, dress is pressed with boss bolt.
Described spin is made up of GCr15.
Dust cover is provided with between described outward flange dish and half inner ring.
The invention has the beneficial effects as follows: the hub-bearing unit that the invention provides a kind of high speed high-mechanic, its first, second and third and four alleys on be equipped with retainer, spin is provided with in retainer, described spin can work in the mode of ball bearing on the one hand, on the other hand two spin form the synchronous axial system of similar needle bearing, and this hub-bearing unit has that structure is simple, the advantage of high speed high-mechanic.
Accompanying drawing explanation
Fig. 1 is the sectional view of one embodiment of the invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described: as shown in the figure, a kind of hub-bearing unit of high speed high-mechanic, comprise outward flange dish 1 and inner flange 3, described inner flange 3 secure fit has half inner ring 2, the first raceway 31 and the second raceway 32 is formed between described outward flange dish 1 one end and inner flange 3, the 3rd raceway 33 and the 4th raceway 34 is formed between the other end and described half inner ring 2, described first, two, retainer 5 is equipped with in three and four raceways, spin 4 is provided with in described retainer 5, described first, the angle a formed between two groove-section axial connecting lines and horizontal line is greater than 0 ° and is less than 90 °, described 3rd, the angle a formed between four groove-section axial connecting lines and horizontal line is greater than 0 ° and is less than 90 °.The point cantact of traditional ball bearing is made into by the contact that same cross section is at least made up of two spin, significantly increase bearing capacity not falling under slow-revving prerequisite, angle a is greater than 0 ° and is less than 90 ° in scope, using effect is better, the invention provides a kind of hub-bearing unit of high speed high-mechanic, it is first years old, two, three and four alleys are equipped with retainer, spin is provided with in retainer, described spin can work in the mode of ball bearing on the one hand, another aspect two spin form the synchronous axial system of similar needle bearing, it is simple that this hub-bearing unit has structure, the advantage of high speed high-mechanic.
