Background technique
Power transmission is widely used in automobile industry, such as, in the starting drive of automobile, just power transmission is housed.When starting up the car, cooperatively interacting between starting drive and motor, completing whole start-up course.Initial stage, starting drive work, and by power transmission by power transmission to motor, thus drive engine operation.After motor is activated, its rotating speed is greater than the rotating speed of starting drive, and now starting drive completes task, and automatically and motor depart from.
Power transmission weares and teares to reduce and realizes one-way clutch, need multiple roller and flat spring cooperation rotation are installed in the one-way clutch groove of clutch pinion, in order to reduce friction, generally all need to lubricate at roller place grease, grease can be thinning under high speed rotating, and throw away along with rotation at a high speed, cause the wearing and tearing between roller, transmission shaft, clutch pinion, therefore at present general on transmission shaft sheathed back-up ring carry out shutoff one-way clutch groove, but its sealing effect is not good, can not stop lubricant oil throw away and extraneous dust enters one-way clutch groove.In addition, this structure is when surmounting, and flat spring is easily out of shape, and contraction can not resilience and losing efficacy, and causes clutch pinion ineffective.
Summary of the invention
The object of this invention is to provide a kind of effective raising functional reliability and the power transmission that can increase the service life.
The technological scheme realizing the object of the invention is: a kind of power transmission with clutch mechanism, comprises transmission shaft, clutch pinion, cover cap and back-up ring; One end of clutch pinion is provided with joint part, and the other end is provided with assembly department; Transmission shaft periphery wall is provided with the annular joint of evagination, and the joint part of clutch pinion is set on this annular joint; The one-way clutch groove for multiple circumferentially equidistant arrangement is provided with in the center hole of clutch pinion joint part; Its structural feature is: also comprise a divider; One end away from clutch pinion of transmission shaft annular joint is provided with annular breach; Divider comprises fixing part and the annular and separation boss for each one-way clutch groove being separated into two holding cavities from evagination fixing part periphery wall of annular, be equipped with a roller in each holding cavity and one provide the flat spring of reseting elasticity for this roller.
In such scheme, divider is provided with annular groove on its periphery wall away from one end of clutch pinion assembly department, is provided with O-ring seal in this annular groove, and this ring seal ring blocks the gap between back-up ring and transmission shaft annular joint.
In such scheme, O-ring seal is provided with the fixing part for being embedded in annular groove and exposes the sealed department of annular groove; Back-up ring comprises with closure part, pressure contact portion and the arc shaped transition part that connects between pressure contact portion and sealed department; Closure part is set on the periphery wall of transmission shaft annular joint, and block the side opening of each clutch slot away from clutch pinion assembly department, pressure contact portion is connected to transmission shaft annular joint away from a side end face of clutch pinion assembly department, and transition part is crimped on the sealed department of O-ring seal on the outer wall of transmission shaft annular joint.
In such scheme, cover cap is crimped on clutch pinion joint part away from a side end face of assembly department the closure part of back-up ring.
The present invention has the following advantages: (1) owing to being provided with the annular and separation boss for each one-way clutch groove being separated into two holding cavities of evagination on the periphery wall of divider, and in each holding cavity, be equipped with a roller and one provide the flat spring of reseting elasticity for this roller; When the roller in the holding cavity of in a clutch slot or flat spring damage, roller in another holding cavity and flat spring still can continue normal work, realize reliable clutch effect, the roller that can not have been damaged or the obstruction of flat spring, so the present invention effectively can improve functional reliability and can increase the service life.In addition, structure of the present invention is comparatively reasonable, and process for machining and manufacturing is easy, and cost is lower.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention;
A kind of structural representation when Fig. 2 is flat spring and roller cooperating in power transmission shown in Fig. 1.
Embodiment
(embodiment 1)
Fig. 1 to Fig. 2 shows a kind of embodiment of the present invention, and wherein Fig. 1 is a kind of structural representation of the present invention; A kind of structural representation when Fig. 2 is flat spring and roller cooperating in power transmission shown in Fig. 1.
The present embodiment is a kind of power transmission with clutch mechanism, sees shown in Fig. 1 to Fig. 2, comprises transmission shaft 1, clutch pinion 2, cover cap 3, back-up ring 4, actuation gear 51, jump ring 52, jump ring cover 53, stage clip 54 and divider 9; One end of clutch pinion is provided with joint part 21, and the other end is provided with assembly department 22; Transmission shaft periphery wall is provided with the annular joint 11 of evagination, and the joint part of clutch pinion is set on this annular joint; The one-way clutch groove 23 for multiple circumferentially equidistant arrangement is provided with in the center hole of clutch pinion joint part; One end away from clutch pinion of transmission shaft annular joint is provided with annular breach 14; Divider comprises fixing part 91 and the annular and separation boss 92 for each one-way clutch groove being separated into two holding cavities 24 from evagination fixing part periphery wall of annular, be equipped with a roller 6 in each holding cavity and one provide the flat spring 7 of reseting elasticity for this roller.
