Among the figure: gland 1, corrugated gasket 2, handle mounting bracket 3, transmission roller 4, roller rolling retainer 5, star-wheel 6 is stirred seat 7, interior retracing spring 8, outer retracing spring 9, shell 10, drive sleeve 11, self-locking roller 12, spring leaf 13, base plate 14 is installed, friction ring 15, gear wheel shaft 16, gear 17, hole, corresponding wedge angle 18, blossom type endoporus 19, interior retracing spring positioning seat 20, star wheel limiting seat 21, star-wheel positioning seat 22, in reset stir the seat 23, outer retracing spring positioning seat 24, handle 25.
The specific embodiment
Referring to Fig. 1-Fig. 7, present embodiment is mainly by gland 1, handle mounting bracket 3, transmission roller 4, roller rolling retainer 5, star-wheel 6 is stirred seat 7, interior retracing spring 8, outer retracing spring 9, shell 10, drive sleeve 11, self-locking roller 12, spring leaf 13 is installed base plate 14, friction ring 15, gear wheel shaft 16, gear 17, hole, corresponding wedge angle 18, blossom type endoporus 19, interior retracing spring positioning seat 20, star wheel limiting seat 21, star-wheel positioning seat 22, in reset and stir seat 23, outer retracing spring positioning seat 24 and handle 25 formed.
In the present embodiment, after drive sleeve 11 and shell 10 are inserted in an end of gear wheel shaft 16, hole, eight corresponding wedge angles 18 occurs, in this hole, eight corresponding wedge angles 18, two self-locking rollers 12 and spring leaf 13 are installed, friction ring 15 is snapped in the other end that is inserted in gear wheel shaft 16 behind the base plate 14 is installed; Base plate 14 and shell 10 riveted and fixed are installed; Interior retracing spring positioning seat 20, star-wheel positioning seat 22 and outer retracing spring positioning seat 24 are connected as a single entity with shell 10, and outer retracing spring 9 is installed on the shell 10, and the two ends of this outer retracing spring 9 are stuck in the both sides of outer retracing spring positioning seat 24 just.
Star-wheel 6 and corrugated gasket 2 are inserted in handle mounting bracket 3, and handle 25 is fixed on the handle mounting bracket 3, and handle mounting bracket 3 is with star-wheel 6 and stir seat 7 riveted and fixed formation star-wheel assembly I; Stir seat 7 and star wheel limiting seat 21 and be structure as a whole, the endoporus of star-wheel 6 is blossom type endoporus 19; Roller rolling retainer 5 and in reset and stir seat 23 and be structure as a whole, transmission roller 4 and roller rolling retainer 5 sandwich just in the blossom type endoporus 19 and coincide; Interior retracing spring 8 is installed on the roller rolling retainer 5, resets in two ends of retracing spring 8 are stuck in just in this and stir the both sides of seat 23.
Because the present invention has hole, eight corresponding wedge angles 18, in hole, eight corresponding wedge angles 18 two self-locking rollers 12 and spring leaf 13 is installed, one of them is the rotating function of power-transfer clutch, and automotive seat will be up and down; Another is that the seat upward pressure is big more under the effect of two self-locking rollers 12 in hole, corresponding wedge angle 18 and spring leaf 13, and it is just tight more that self-locking roller 12 is embraced gear wheel shaft 16 tightly, and seat can be arbitrarily not up and down.
During use, gear 17 is connected with connecting rod with the tooth plate of the up and down mechanism of automotive seat, as long as move handle 25 this moment, after bidirectional clutch of the present invention rotates, the tooth plate and the connecting rod of the up and down mechanism of gear 17 driving automobile seats, automotive seat will be up and down.
Referring to Fig. 8, the principle of work and the working process of bidirectional clutch of the present invention are as follows:
Seat rising function: bar handle 25 turning handle mounting brackets 3, the blossom type endoporus 19 of star-wheel 6 is embraced drive sleeve 11 tightly with 12 transmission rollers 4, and drive sleeve 11 is and then rotated together, drive sleeve 11 pulls away gear wheel shaft 16 with self-locking roller 12 and forms hole, corresponding wedge angle 18 with drive sleeve 11, driven gear axle 16 rotates together, realizes the operation transmission.Operation is each time undertaken spacingly by stirring seat 7 and star-wheel positioning seat 22 above the shell 10, makes the angle unanimity of each operation rotation.Behind the EO, utilize the friction force that is fixed on the brake hoop 15 above the installation base plate 14 to make drive sleeve 11 and gear wheel shaft 16 rest on original position each time; Star-wheel assembly I is return under the effect of retracing spring 9 outside then, and corrugated gasket 2 is in order to eliminate endplay; Interior retracing spring 8 makes roller rolling retainer 5 drive 12 transmission rollers 4 return together, and finishes an operation cycle.
Seat decline function: reverse operating gets final product, and principle is with above-mentioned consistent.
When external force is applied on the gear 17 of gear wheel shaft 16, withstand under the effect of spring leaf 13 because of self-locking roller 12 in the wedge angle of gear wheel shaft 16 outsides and shell 10 inwalls, make gear wheel shaft 16 be locked and can not rotate, play self-locking action.
