By the known a kind of freewheel retainer for clip body of DE 10 2,008 030 017 A1.This freewheel retainer has multiple retainer pocket portion arranged in the mode be distributed in circumferentially, in these retainer pocket portions, be furnished with clip body.Clip body guides by the edge in retainer pocket portion.Freewheel retainer has the outward edge shape of tubular.
Summary of the invention
Task of the present invention is, provide a kind of can the cheap freewheel retainer manufactured.
According to the present invention, this task is solved by a kind of freewheel retainer with matrix, wherein, matrix has two retainer rings around common axis arranged, and wherein, retainer contact pin axially extends between two retainer rings, construct retainer pocket portion thus, and wherein, retainer ring and retainer contact pin formula ground integral with one another structure, and one in two retainer rings there is integral molding as follows and the element protruded diametrically, that is, make the element of this protrusion for torsion anti-in freewheel.
Freewheel retainer is used for different freewheel types.Freewheel retainer self is for holding clip body/clip roller and spring element.Freewheel retainer is arranged between actuator and driven member mostly, this freewheel retainer and actuator otherwise with driven member in anti-relative rotation (drehfest) be connected.
In freewheel retainer according to the present invention, form retainer ring and the retainer contact pin formula ground integral with one another structure of matrix, and in addition, one of them retainer ring has the element of the protrusion of integral molding.The advantage of the one-piece construction of matrix resides in reduced production stage and manufacture cost, this is because eliminate all parts, such as retainer ring and retainer contact pin welding or riveted joint etc. to each other.
The element of multiple protrusion arranged in the mode be distributed in circumferentially is favourable, that is, such as, to attach troops to a unit the element protruded to each retainer pocket portion.The element protruded is used for guaranteeing to prevent freewheel retainer from reversing in freewheel on the one hand.When can be implemented in assembling by the element protruded on the other hand, freewheel retainer is positioned in freewheel exactly.Thus, can avoid assemble time occur mistake, such as retainer contact pin curved or spring compacted.
In a preferred make, the exterior contour of the element of protrusion has the domatic profile matched with clip.Thus, the element of protrusion can be made to be embedded in the domatic region of the clip of freewheel, thus to make the anti-torsion of freewheel retainer.Preferably, the element of protrusion is constructed such that its exterior contour is corresponding to by the domatic recess formed of clip.Exterior contour also can be designed to make it corresponding to the domatic whole trend of clip or part trend.
In a favourable design proposal, matrix is made up of steel band, and the end of matrix is welded to one another.Different retainer diameters is produced at an easy rate by it is possible to of realizing of the matrix be made up of steel band.Retainer pocket portion is stamped out in shaping retainer steel band.Steel band is opened so that corresponding length is divided and is then bent.End is welded to one another.The element of the protrusion of one-piece construction on retainer ring is bent in the corresponding direction.
In another preferred design proposal of the present invention, matrix has the transverse section of section material of W shape.
Preferably, freewheel retainer is arranged in clip roller freewheel mechanism.Clip roller freewheel mechanism has the freewheel retainer of ring and layout adjacent with this ring, and it is domatic that this ring has clip.In freewheel retainer, be provided with clip roller and spring element, wherein, spring element is facing to clip domatic elasticity pressing clip roller.Ring can be configured to outer shroud or inner ring.
Preferably, the element of the protrusion of freewheel retainer is embedded into by the domatic recess formed of clip.This can be realized by the corresponding exterior contour of the element protruded.
In a preferred design proposal of the present invention, spring element can with end winding support in retainer contact pin.Spring element can such as be fixed on retainer by being fastened and connected, or is fixed on retainer by grab.But, also can expect other connection possibility.
Freewheel can use in different engineering machinery and automotive field, such as, use in the starter motor unit or transmission device of automotive industry.According to the difference of application, the ring of freewheel is configured to outer shroud and inner ring.In the freewheel with outer shroud and in the freewheel with inner ring, working method is all the same.
Accompanying drawing explanation
Below, in conjunction with three accompanying drawings, embodiments of the invention are shown.Wherein:
Fig. 1 illustrates the stereogram according to freewheel retainer of the present invention;
Fig. 2 illustrates the stereogram according to freewheel retainer of the present invention; And
Fig. 3 illustrates the longitudinal section of the freewheel had according to freewheel retainer of the present invention.
Embodiment
Fig. 1 shows according to freewheel retainer 1 of the present invention.Freewheel retainer 1 has matrix 1a.Matrix 1a has two retainer rings 2,3.Retainer contact pin 4 extends between retainer ring 2,3, and they form retainer pocket portion 5 together.Retainer ring 2,3 and retainer contact pin 4 formula ground integral with one another structure.Retainer contact pin 4 has the transverse section of section material of W shape.
Retainer ring 2 has the exterior contour of tubular.Retainer ring 3 has the exterior contour of tubular and has the element 6 of multiple protrusion arranged in the mode be distributed in circumferentially in addition.The element 6 protruded integrally is molded on retainer ring 3 at this.The element 6 protruded is particularly useful for anti-torsion in freewheel.As seen from Figure 1, the element 6 of protrusion is arranged in the region in retainer pocket portion 5, but wherein, the element 6 of protrusion does not extend in the whole length in retainer pocket portion 5.
As seen from Figure 2, in retainer pocket portion 5, spring element 7 and clip roller 8 is provided with.Spring element 7 is supported in retainer contact pin 4.In this embodiment, spring element 7 is configured to through repeatedly folding sheet spring 9.
Fig. 3 shows the longitudinal section had according to freewheel retainer 1 of the present invention.
As can be seen, freewheel 10 has outer shroud 11, and this outer shroud is configured to the parts of tubular.The internal surface of outer shroud 11 is configured with clip domatic 12, and the track of the cylinder shape of the domatic and unshowned parts of these clips, such as axle forms clip gap 15.Clip gap 15 forms narrow positions 16 in side.Spring element 7 is facing to the domatic 12 elasticity pressing clip rollers 8 of clip, and that is, clip roller 8 is clamped in clip gap 15.
At opposite side, the clip gap 15 formed by clip domatic 12 forms recess 13.The element 6 of the protrusion of freewheel retainer 1 is embedded in recess 13.For this reason, the exterior contour 14 of the element 6 of protrusion matches with this region of clip domatic 12.
