One end, connected with the gear, of the star wheel is provided with a protruding connection portion, and the other end, far away from the gear, of the star wheel is provided with a sliding shaft portion. A plurality of one-way clutch grooves which are arrayed in the circumferential direction at the same intervals are formed in central holes of the star wheel connection portion. A composite pin roller and a double-spring type flat spring for providing reset elasticity for the pin roller are arranged in each one-way clutch groove. Each composite pin roller is formed by combing two monomeric pin rollers in concentric and adjacent modes, and each double-spring type flat spring is made of a metal wire and provided with two elastic flat spring portions. Each elastic flat spring portion abuts against a position between the wall of one one-way clutch groove and a corresponding monomeric pin roller. The improved type isolator assembly effectively improves safety and prolongs service life.
Description
Technical field
The utility model belongs to the one-way element assembly structure and relates to technical field, is specifically related to a kind of modified model one-way element assembly for automobile.
Background technique
The one-way element assembly is widely used in automobile industry, and the one-way element assembly for example just is housed in the starting drive of automobile.When starting up the car, cooperatively interact between starting drive and the motor, finish whole starting process.Initial stage, starting drive work, and by one-way element power is transferred to motor, thus drive engine operation.After motor was activated, its rotating speed was greater than the rotating speed of starting drive, and this moment, starting drive was finished task, and automatic and motor disengaging.
The one-way element assembly is in order to reduce wearing and tearing and to realize one-way clutch, a plurality of rollers and flat spring need be installed in the one-way clutch groove of star-wheel cooperate rotation, in order to reduce friction, generally all need coat grease at the roller place lubricates, grease can be thinning under high speed rotating, and along with rotation at a high speed throws away, cause the wearing and tearing between roller, gear, the star-wheel, therefore at present generally on gear sheathed back-up ring come shutoff one-way clutch groove, but its sealing effect is not good, can not stop lubricant oil throw away and extraneous dust enters the one-way clutch groove.In addition, this structure when surmounting, the flat spring easy deformation, contraction can not resilience and was lost efficacy, and causes one-way element ineffective.
Summary of the invention
The purpose of this utility model provides the modified model one-way element assembly in a kind of effective improving safety energy and working life.
The technological scheme that realizes the utility model purpose is: a kind of modified model one-way element assembly comprises gear, star-wheel, cover cap and metal collar; Star-wheel is provided with the joint part of evagination at its end that is connected with gear, is provided with slide-bar portion at its other end away from gear; Be provided with the one-way clutch groove for the circumferential equidistant arrangement in a plurality of edges in the center hole of star-wheel joint part, be provided with compound roller in each one-way clutch groove and be used to this roller that the double-spring type flat spring of reseting elasticity is provided; Described compound roller is concentric on being arranged in a combination by two monomer rollers, and described double-spring type flat spring is to be made by same wire, and has two elasticity flat spring portions; Each elasticity flat spring portion is connected to respectively between one-way clutch groove cell wall and the corresponding monomer roller.
The utlity model has following advantage: owing to adopt the comparatively rational compound roller of structure and be used to this roller that the double-spring type flat spring of reseting elasticity is provided, when one of them monomer roller or elasticity flat spring portion damage, also have a cover elasticity flat spring portion and the monomer roller still can proper functioning, thereby effectively improved the safety reliability of one-way element assembly.
