Constitute.Intersecting in which region according to arm, spring element has similar X, the shape of similar Y or similar V.Spring element this
Planting construction can realize reducing manufacturing cost.Additionally, designing spring element as follows, i.e. via in the region for limiting
Torsion produce spring effect mechanism.Additionally, design that structure space is saved by this spring, because in locking position
Putting middle spring element needs less structure space.In addition, for compared to helical spring, it is not necessary to spring element is carried out attached
Plus guiding.
In preferred structural scheme, the end towards retainer contact pin of spring element is bending, and by horizontal stroke
It is connected to each other to contact pin.The region of spring element constitutes torsion region.Horizontal contact pin is walked at it and may be embodied as straight line upwards
Shape, can have and arch upward portion or all other shape.Additionally, this construction of the end for passing through spring element can be realized
Connection on retainer.
In favourable design, retainer contact pin has the recess of pocketed respectively, and spring element is kept using direction
The end of bridge joint piece is embedded into recess.Recess can for example be set or only range selector on the whole width of retainer contact pin
Ground is set.Except in pocketed, recess can also be embodied as slot-shaped or implement in other forms.Advantageously, in retainer contact pin
In recess be matched with spring element the end towards retainer contact pin shapes and sizes.The corresponding end of spring element
Can be fixed on by way of pushing or buckling into freewheel retainer or on freewheel retainer.Additionally,
Spring element end releasably or can be permanently connected with freewheel retainer or retainer contact pin.
In another preferred design of the invention, the end tabs shape ground structure towards clip body of spring element
Make.Tongue-shaped end orthogonally can protrude from the arm of spring element herein.By such an arrangement avoids each spring element
Part is stuck before assembly.In addition can realize reliably suppressing clip body, it is possible thereby to avoid failure.
In preferred design of the invention, the end towards clip body of spring element constructs hook-shapedly.This can be with
Realization is reliably suppressed clip body.Thus avoid for example causing the failure that improve abrasion.
In another design of the invention, spring element is made up of wire, it is possible thereby to realize that this spring is several
What structure.Wire is selected as follows herein, i.e. can realize spring effect mechanism by reversing.Wire
Shape of cross section for example can be rounded.It is also contemplated that other cross sectional shapes, as flat wire, quadrangle metal
Silk or profiled metal silk.It is contemplated that metal material or plastics with the performance being suitable for the application of are used as raw material.
Advantageously, clip body is configured to clamp-type roller.As an alternative, it is also contemplated that clamp-type needle roller.
Preferably, freewheel retainer can be arranged in freewheel.Freewheel have ring and with
The freewheel retainer that ring is adjacently positioned, wherein, it is domatic that the ring is equipped with clip, and wherein, and spring element is against card
Folder is domatic to suppress clip body.Clip body is preferably configured as clamp-type roller.The ring can be structured as outer shroud or inner ring.
Freewheel can be used in different industrial circles and automotive field, as example applying in starter motor
In the transmission device of unit or automotive industry.According to application, the ring of freewheel can be structured as outer shroud or inner ring.
In the case of the freewheel with outer shroud and in the case of the freewheel with inner ring, working method is all one
Sample.
Brief description of the drawings
Below, embodiments of the invention are shown with reference to three accompanying drawings.Wherein：
Fig. 1 shows the stereogram of the spring element of the invention according to first embodiment,
Fig. 2 shows the stereogram of the spring element of the invention according to second embodiment, and
Fig. 3 shows the partial view of the freewheel retainer with spring element of the invention.
Specific embodiment
Fig. 1 shows the spring element 1 according to first embodiment, and it is made up of wire.Spring element 1 passes through two
The arm of intersection is constituted, and they have arm angle α.The orthogonally bending of first end 4 of the arm 2,3 of spring element 1, and by horizontal stroke
It is connected to each other to contact pin 5.The one side of end 4 is used to make spring element 1 be connected with freewheel retainer.On the other hand,
The end 4 is set to constitute torsion region 6.
The second end 7 of the arm 2,3 of spring element 1 is constructed tongue-shapedly.That is, arm end 2b, 3b are orthogonal first
Bending, and upwardly extended in the side of arm 2,3 after further bending.
Fig. 2 shows the second embodiment of spring element of the invention 1.In order to simplify description, with phase in Fig. 1
Same reference name identical part.
Spring element shown in figure 21 is made up of the arm 2,3 of two intersections.The first end of the arm 2,3 of spring element 1
Portion 4 is constituted like that as depicted in figure 1.Difference is the construction of the second end 8.
The second end 8 has two end 2c, 3c of orthogonal bendings.This means these ends it is hook-shaped construct.
It is illustrated below and illustrates use of the spring element 1 in freewheel retainer.
Fig. 3 shows the Local map of freewheel retainer 9.Freewheel retainer 9 has matrix 9a.Matrix 9a
With two retainer rings 10,11.Retainer contact pin 12 extends between two retainer rings 10,11, and they constitute guarantor together
Hold frame pocket portion 13.Be provided with clamp-type roller 14 in retainer pocket portion 13, and in quantity with the quantity of clamp-type roller 14
Corresponding one of spring element 1.
Retainer pocket portion 12 has the recess 15 of pocketed.The recess 15 of pocketed prolongs on the whole width of retainer contact pin 12
Extend retainer ring 2,3.Spring element 1 is embedded into recess 15 using its first end 4.Therefore, by the transverse direction of spring element 1
Contact pin 5 is radially pushed into recess 15.
The second end 8 of spring element 8 is used to suppress clamp-type roller 14.Clamp-type roller 14 herein with arm end 2c,
3c is contacted.
If clamp-type roller is elapsed to the direction of spring element 1, the increase of arm angle α.It means that by towards
The direction of spring element 1 elapses clamp-type roller 14, and arm 2 and 3 is moved apart from each other.As long as clamp-type roller 14 is again along phase
Anti- direction motion, arm angle α just reduces again.This can be realized by the torsion region 6 of spring element.
As seen from Figure 3, freewheel retainer will be placed to according to the spring element 1 of second embodiment
In 9.However, the function and arrangement of spring element 1 according to first embodiment are identicals.
