Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.Among the figure, turning collar 1, adjustment cover 2, active rotating shaft 3, big torsion spring 4, little torsion spring 5, adjustment are applied mechanically jump ring 6, active rotating shaft with back-up ring 7, first turning collar 8, second turning collar 9.
Embodiment:
A kind of overrunning clutch that is used for the air-pressure disc brake clearance self-regulating mechanism; Comprise and adjust cover 2 and be set in the turning collar 1 that also links to each other in the adjustment cover 2 through one-level driving mechanism and adjustment cover 2; Also be arranged with that link to each other an and end in the adjustment cover 2 and be provided with some active rotating shafts 3 that are used for the fixedly spline that moment of torsion exports through secondary driving mechanism and turning collar 1; Active rotating shaft 3 and turning collar 1 are fixed in the described adjustment cover 2 through fixing device; Adjustment cover 2 outer walls also are provided with the bayonet socket 17 that is used for input torque, and fixing device comprises that an active rotating shaft that is arranged on turning collar 1 upper-end surface is with back-up ring 7 and turning collar 1 is fastened on the 2 interior adjustment of adjustment cover applies mechanically jump ring 6.
Turning collar 1 is a cold extrusion forming spare, is the transition piece that the moment of rotation of adjustment cover is delivered to active rotating shaft.
Active rotating shaft 3 is alloy junction members, is the output terminal of adjustment cover 2 assembly moments of torsion, and its inside function is to receive the moment of torsion that is transmitted by little torsion spring 5.Being designed with spline structure on it, is the key character that output torque is given the next stage parts.
Turning collar 1 comprises first turning collar 8 and is arranged on second turning collar 9 in first turning collar 8; The one-level driving mechanism comprises that an end and adjustment cover 2 inwall interference fit and cross section are the big torsion spring 4 of rectangle, big torsion spring 4 the other ends and first turning collar, 8 inwall interference fit; Because of the torsional stiffness of big torsion spring is bigger, so when external force is rotated adjustment cover 2, turning collar 1 also will rotate thereupon, promptly big torsion spring 4 be similar to above both connect into a rigid body.
The secondary driving mechanism comprises that an end and said second turning collar, 9 outer wall interference fit and cross section are the little torsion spring 5 of rectangle; Little torsion spring 5 the other ends and described active rotating shaft 3 outer wall interference fit; The torsional stiffness of little torsion spring is less; So can turning collar 1 rotate with active rotating shaft, also depend on the direction of moment of torsion.If the moment of torsion that little torsion spring 5 diameters are reduced, when external force rotated circle 1,3 of active rotating shafts also can rotate thereupon so; Otherwise if the moment of torsion that little torsion spring 5 diameters are increased rotates one of them part so, another part does not change.
Jump ring 6 is applied mechanically in adjustment, active rotating shaft is elastic element with back-up ring 7; Its function is that above each part is connected into an integral body; Realize the effect of overrunning clutch; Active rotating shaft 3 is axially fixed in the turning collar through little Steel Cable Baffle Ring 7, and promptly above 7 parts have been formed an integral body: adjustment cover assembly.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
Although this paper has used turning collar 1, adjustment cover 2, active rotating shaft 3, big torsion spring 4, little torsion spring 5, adjustment to apply mechanically jump ring 6, active rotating shaft with terms such as back-up ring 7, first turning collar 8, second turning collars 9 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain the essence of the utility model more easily; It all is contrary with the utility model spirit being construed to any additional restriction to them.
