Description
Technical field
It is specifically a kind of to prevent from failing the one-way clutch of two-way skidding because of support spring the present invention relates to clutch
Device.
Background technology
Currently, all automobile starters with one-way clutch mainly by sleeve, rotation axis, roller, support spring etc. zero
Component forms, and has several equally distributed grooves in the inner wall of sleeve body, groove includes cambered rollers working face and L-shaped
Spring supporting room.Support spring steel wire wound is two steel wire outer circles being connected with roller-contact, and one end is supported on
One face of L-shaped spring supporting room, the other end acts on roller, by roller top pressure between curved working face and rotation axis.
Since one of L-shaped spring supporting room be not stop smoothly towards center, when work, stress when roller stress moves forward
Unevenness is easy to tilt, the direction of axis line of support spring variation cause support spring centripetal deviation and rotation axis fretting wear and
Spring bearing up-down force unevenness deforms, support spring initial failure, the two-way skidding of isolator.
Invention content
The present invention is in view of the above-mentioned problems, providing a kind of can prevent from failing the one-way clutch of two-way skidding because of support spring.
Technical solution according to the invention：It is a kind of to prevent from failing the one-way clutch of two-way skidding because of support spring,
It is characterized in that：Sleeve including barrel shape, the sleeve lining are uniformly arranged several grooves, and groove includes arc transition connection
Curved working face, L-type spring supporting room；Rotation axis is set in the hub internal bore, roller, L-type are set in curved working face
Support spring is set in spring supporting room, and described support spring one end is pressed on roller, and the other end is pressed in L-type spring supporting
On the spring supporting face of room, the roller is tangent with curved working face and rotation axis simultaneously, and L-type spring supporting room and arc
The junction of shape working face is at a distance from bushing core more than the far-end of curved working face at a distance from bushing core.
As a further improvement on the present invention, the end of L-type spring supporting room is downwardly extending projecting block, described
Projecting block is arc-shaped or rectangular.
As a further improvement on the present invention, angulation is α, the range of α between two support arms of L-type spring supporting room
It is 80 ° ~ 95 °.
As a further improvement on the present invention, the support spring is to support bullet about centrosymmetric double bow-shaped structurals
The endface of spring is embedded at the spring supporting face of L-type spring supporting room, two roller support faces of support spring respectively with rolling
The crest line of column offsets up and down, two roller support faces it is flexible independently of each other.
The technical effects of the invention are that：Product design of the present invention is skillfully constructed, and curved working face and L are designed on sleeve
Type spring supporting room, and the slot bottom of curved working face is designed to radian shape, and the trend of the radian is closer to L-type bullet
Spring supported chamber side, further away from the center of sleeve, in order to realize one-way locking, i.e. rotation axis is towards L-type spring supporting room one
When side rotates, roller is retreated towards support spring side, and compresses support spring, at this time isolator slipping；Rotation axis court
When being rotated to projecting block side, the curved working face distal end of roller to sleeve is mobile, is lockable, isolator transmits torque at this time.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Fig. 2 is the support spring sectional view of the present invention.
Fig. 3 is the structural schematic diagram before the present invention.
Specific implementation mode
The specific implementation mode of the present invention is further described below in conjunction with the accompanying drawings.
In Fig. 1 ~ 3, including sleeve 1, groove 1-1, curved working face 1-2, L-type spring supporting room 1-3, rotation axis 2, roller
3, the distal end b of the junction a, curved working face of support spring 4, L-type spring supporting room and curved working face, spring supporting face c,
Projecting block d, the end face e of support spring, roller support face f etc..
As shown in Fig. 1 ~ 3, the present invention be it is a kind of can prevent from failing the one-way clutch of two-way skidding because of support spring, including
The arc that several grooves 1-1, groove 1-1 include arc transition connection is arranged in the sleeve 1 of barrel shape, 1 inner wall even distribution of the sleeve
Shape working face 1-2, L-type spring supporting room 1-3；Rotation axis 2 is set in 1 endoporus of the sleeve, rolling is set in curved working face 1-2
Support spring 4 is arranged in L-type spring supporting room 1-3 for column 3, and 4 one end of the support spring is pressed on roller 3, and the other end compresses
In on the spring supporting face of L-type spring supporting room 1-3, the roller 3 is tangent with curved working face 1-2 and rotation axis 2 simultaneously, and
It is more than curved working face 1- at a distance from the junction a of L-type spring supporting room 1-3 and curved working face 1-2 and 1 center of sleeve
At 2 distal end b at a distance from 1 center of sleeve.
The end of L-type spring supporting room 1-3 is downwardly extending projecting block d, and the projecting block d is arc-shaped or rectangular.
Between two support arms of L-type spring supporting room 1-3 angulation be α, ranging from 80 ° ~ 95 ° of α.
Support spring 4 is to be embedded in L-type spring branch at the end face e of support spring 4 about centrosymmetric double bow-shaped structurals
At the spring supporting face c for supportting room 1-3, two roller support face f of support spring 4 offset with the crest line of roller 3 up and down respectively, and two
A roller support face f's is flexible mutual indepedent.
The principle of the present invention is as follows：Due to the junction a and sleeve 1 of L-type spring supporting room 1-3 and curved working face 1-2
At distal end b of the distance at center more than curved working face 1-2 at a distance from 1 center of sleeve, arc work of the rotation axis 2 around sleeve 1
Make face 1-2 towards when rotating at the b of distal end, roller 3 locates mobile up to being locked, isolator at this time to the curved working face b of sleeve 1
Transmit torque；When rotation axis 2 around supporting surface side a prescriptions to when rotation, roller 3 is to the curved working face a prescriptions of sleeve 1 to shifting
Dynamic retreat is skidded, at this time isolator slipping.
