Abstract
The utility model belongs to aluminium casting steering machine technical field, discloses a kind of aluminium casting steering machine.It is mainly characterized in that：Including the housing with swing arm axis hole, side cover and rocker arm shaft, housing side is provided with positioning inner ring in the side cover, in the arm shaft front end insertion positioning inner ring, the first needle roller bearing without inner ring is provided with the inside of the positioning inner ring, in described described first needle roller bearing without inner ring of arm shaft front end insertion.So, the frictional force between positioning inner ring and rocker arm shaft can effectively be reduced, and housing and side cover can be using the aluminum castings of lighter in weight, significantly reduce the weight of steering machine, the stability of motor vehicle is improve, particularly with the motor vehicle of the lighter in weight such as perambulator, stability improves more obvious, and abrasion between side cover and rocker arm shaft is also greatly reduced, improve the service life of side cover.
Description
Technical field
The utility model belongs to steering machine technical field, more particularly to a kind of aluminium casting steering machine.
Background technology
In motor vehicle power steer field, it is spheroidal graphite cast-iron to turn to the housing of machine, the material of side cover, and rocker arm shaft material is
20CrMnTi nitrogencase hardenings.Rocker arm shaft rotates to form sliding friction with housing, side cover.Spheroidal graphite cast-iron have self-lubricating function and
There is lubricating oil in steering gear cavity.There is following defect in above-mentioned steering machine：First, the machine of steering overall volume is big, take up room big；
Second, weight is big, light weight is not only increased, and it is poor to also result in intact stability, especially on the dillies such as perambulator,
Drawbacks described above is more obvious；Third, rocker arm shaft and housing and side cover direct friction, increase their direct frictional force, cause
Difficulty is turned to, the service life of housing, side cover and arm shaft is reduced.
Utility model content
Problem to be solved in the utility model is just to provide the good aluminium of a kind of long service life, lightweight, intact stability
Casting steering machine.
To solve the above problems, the utility model aluminium technical scheme for using of casting steering machine for：Including with swing arm axis hole
Housing, side cover and rocker arm shaft, housing side is provided with positioning inner ring in the side cover, institute is inserted in the arm shaft front end
State in positioning inner ring, the first needle roller bearing without inner ring is provided with the inside of the positioning inner ring, institute is inserted in the arm shaft front end
State in the first needle roller bearing without inner ring.
Its additional technical feature is：
The second needle roller bearing without inner ring is provided with the swing arm axis hole, the arm shaft penetrates described second without inner ring
In needle bearing, described hull outside one end is provided with oil seal washer in second needle roller bearing without inner ring.
Aluminium provided by the utility model casts steering machine compared with prior art, with advantages below：First, due to including
Housing, side cover and rocker arm shaft with swing arm axis hole, positioning inner ring, the swing arm are provided with the side cover positioned at housing side
In the axle front end insertion positioning inner ring, the first needle roller bearing without inner ring, the swing arm are provided with the inside of the positioning inner ring
Axle front end is inserted in first needle roller bearing without inner ring, so, can effectively reduce rubbing between positioning inner ring and rocker arm shaft
Power is wiped, and housing and side cover can significantly reduce the weight of steering machine using the aluminum casting of lighter in weight, improve motor-driven
The stability of car, particularly with the motor vehicle of the lighter in weight such as perambulator, stability improves more obvious, but also substantially reduces
Worn and torn between side cover and rocker arm shaft, improve the service life of side cover；Second, due to being provided with the swing arm axis hole
Two needle roller bearing without inner rings, the arm shaft is penetrated in second needle roller bearing without inner ring, described second without inner ring needle roller
Bearing is provided with oil seal washer near described hull outside one end, equally greatly reduces the frictional force between housing and rocker arm shaft,
The abrasion of housing is reduced, housing service life is extended.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model aluminium casts steering machine.
Specific embodiment
With reference to the accompanying drawings and detailed description to the utility model aluminium casting steering machine structure and use principle do into
One step is described in detail.
As shown in figure 1, the utility model aluminium casts the structural representation of steering machine, the utility model aluminium casting steering machine includes band
There are housing 2, side cover 3 and the rocker arm shaft 4 of swing arm axis hole 1, the side for being located at housing 2 in side cover 3 is provided with positioning inner ring 5, swing arm
In the front end insertion positioning inner ring 5 of axle 4, the inner side of positioning inner ring 5 is provided with the first needle roller bearing without inner ring 6, before arm shaft 4
End is inserted in first needle roller bearing without inner ring 6, so, can effectively reduce the friction between positioning inner ring 5 and rocker arm shaft 4
Power, and housing 2 and side cover 3 can significantly reduce the weight of steering machine using the aluminum casting of lighter in weight, improve motor-driven
The stability of car, particularly with the motor vehicle of the lighter in weight such as perambulator, stability improves more obvious, but also substantially reduces
Worn and torn between side cover and rocker arm shaft, improve the service life of side cover.
The second needle roller bearing without inner ring 7 is provided with swing arm axis hole 1, arm shaft 4 penetrates the second needle roller bearing without inner ring 7
It is interior, the lateral ends of housing 2 are provided with oil seal washer 8 in the second needle roller bearing without inner ring 7, equally greatly reduce housing and shake
Frictional force between arm axle, reduces the abrasion of housing, extends housing service life.
Protection domain of the present utility model is not limited solely to above-described embodiment, as long as structure turns with the casting of the utility model aluminium
It is identical to machine structure, just fall in the scope of the utility model protection.
