Description
Technical field
The utility model relates to technical field of automobile, is specifically related to a kind of spindle.
Background technology
Spindle is one of part main on steering axle of automobile, and it can make vehicle steadily travel and transmit vehicle traveling direction.At present, existing spindle has generally included knuckle body, and the middle part of described knuckle body is provided with one and turns to axis hole, and the side face of described knuckle body is provided with multiple outward extending connecting arm, and each connecting arm is equipped with assembly opening.In actual application, by the impact of the factors such as steering shaft hole surface degree of finish, described in turn to axis hole coordinate with steering shaft turn to time, there is catching phenomenon sometimes, thus greatly affect the sensitieness of motor turning.
Summary of the invention
For the deficiencies in the prior art, the utility model provides one and turns to more flexibly spindle smoothly.
For achieving the above object, the utility model provides a kind of spindle, include knuckle body, the middle part of described knuckle body is provided with one and turns to axis hole, the side face of described knuckle body is provided with multiple outward extending connecting arm, and each connecting arm is equipped with assembly opening, described turning in axis hole is provided with an annular groove, an annular sleeve is embedded with in described annular groove, and the axial two ends of described annular sleeve are also equipped with the extension board extended radially inwardly, two pieces of spring washers are also equiped with in described annular sleeve, and the opposing end face of two spring washers abuts with the extension board at two ends respectively, spring and steel ball is folded with between the end face that two spring washers are relative, described spring correspondence is positioned at radial outer end, described steel ball correspondence is positioned at radial inner end, the two ends of spring abut with steel ball and annular sleeve respectively, the end face that two spring washers are relative is also provided with the spacing rib that restriction steel ball radial direction skids off, the outside face of described annular sleeve and extension board thereof is also provided with wear-resistant material layer.
The beneficial effects of the utility model are: adopt said structure, because the utility model is provided with spring and steel ball described turning in axis hole, therefore described turn to axis hole to coordinate with steering shaft to turn to time, greatly can promote the flexible smoothness that it rotates each other, thus make turning to of automobile smooth and easy more flexibly.Meanwhile, because described spring and steel ball are folded between two spring washers, therefore also effectively can promote damping performance, and described spring, steel ball and two spring washers are all included in annular sleeve and extension board thereof, are then convenient to be mounted with.In addition, the outside face of described annular sleeve and extension board thereof is also provided with wear-resistant material layer, then can greatly extends its service life.
The utility model can be set to described extension board also be provided with the arc-shaped convex embedded in corresponding spring washer further.By above-mentioned setting, can stationary positioned spring washer further, make integral structure more reliable and more stable.
The utility model also can be set to the preferred tungsten carbide wear resistant layer of described wear-resistant material layer further, and its thickness is preferably greater than 0.5mm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is local structural graph of the present utility model.
Detailed description of the invention
As Fig. 1, a kind of spindle is given shown in 2, include knuckle body 1, the middle part of described knuckle body 1 is provided with one and turns to axis hole 11, the side face of described knuckle body 1 is provided with multiple outward extending connecting arm 12, and each connecting arm 12 is equipped with assembly opening 13, described turning in axis hole 11 is provided with an annular groove 14, an annular sleeve 2 is embedded with in described annular groove 14, and the axial two ends of described annular sleeve 2 are also equipped with the extension board 21 extended radially inwardly, two pieces of spring washers 3 are also equiped with in described annular sleeve 2, and the opposing end face of two spring washers 3 abuts with the extension board 21 at two ends respectively, spring 4 and steel ball 5 is folded with between the end face that two spring washers 3 are relative, described spring 4 correspondence is positioned at radial outer end, described steel ball 5 correspondence is positioned at radial inner end, the two ends of spring 4 abut with steel ball 5 and annular sleeve 2 respectively, the end face that two spring washers 3 are relative is also provided with the spacing rib 31 that restriction steel ball 5 radial direction skids off.Described extension board 21 is also provided with the arc-shaped convex 22 embedded in corresponding spring washer 3.The outside face of described annular sleeve 2 and extension board 21 thereof is also provided with wear-resistant material layer 6, and described wear-resistant material layer 6 is tungsten carbide wear resistant layer preferably, and its thickness is preferably greater than 0.5mm.
Adopt said structure, because the utility model is provided with spring 4 and steel ball 5 described turning in axis hole 11, therefore described turn to axis hole 11 to coordinate with steering shaft to turn to time, greatly can promote the flexible smoothness that it rotates each other, thus make turning to of automobile smooth and easy more flexibly.Meanwhile, because described spring 4 and steel ball 5 are folded between two spring washers 3, therefore also effectively can promote damping performance, and described spring 4, steel ball 5 and two spring washers 3 are all included in annular sleeve 2 and extension board 21 thereof, are then convenient to be mounted with.In addition, the outside face of described annular sleeve 2 and extension board 21 thereof is also provided with wear-resistant material layer 6, then can greatly extends its service life.
