Description
Technical field
The invention belongs to the power transmission structure design field, be specifically related to a kind of power transmission with clutch mechanism.
Background technique
Power transmission is widely used in automobile industry, and power transmission 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 power transmission 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.
Power transmission 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 clutch pinion 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, transmission shaft, the clutch pinion, therefore at present generally on transmission shaft 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 clutch pinion ineffective.
Summary of the invention
The power transmission that the purpose of this invention is to provide a kind of effective raising functional reliability and can increase the service life.
The technological scheme that realizes 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; The 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; Be provided with the one-way clutch groove for the circumferential equidistant arrangement in a plurality of edges in the center hole of clutch pinion joint part; Its structural feature is: also comprise a divider; End away from clutch pinion of transmission shaft annular joint is provided with annular breach; Divider comprise the fixing part of annular and from the fixing part periphery wall the annular and separation boss that is used for each one-way clutch groove is separated into two holding cavities of evagination, be equipped with a roller and one in each holding cavity and be used for the flat spring that this roller provides reseting elasticity.
In the such scheme, divider is provided with annular groove at its periphery wall away from an 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 the transmission shaft annular joint.
In the such scheme, O-ring seal is provided with for the fixing part that is embedded in annular groove and the sealed department that exposes annular groove; Back-up ring comprises with closure part, pressure contact portion and the arc shaped transition part of connection between pressure contact portion and sealed department; The closure part is set on the periphery wall of transmission shaft annular joint, and block each clutch slot away from a side opening of clutch pinion assembly department, pressure contact portion is connected on the side end face of transmission shaft annular joint away from the 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 the such scheme, cover cap is crimped on the closure part of back-up ring on the side end face of clutch pinion joint part away from assembly department.
The present invention has the following advantages: (1) since the periphery wall of divider be provided with evagination be used for each one-way clutch groove is separated into the annular and separation boss of two holding cavities, and in each holding cavity, be equipped with a roller and one and be used for the flat spring that this roller provides reseting elasticity; When the roller in the holding cavity in the clutch slot or flat spring damage, roller in another holding cavity and flat spring still can continue proper functioning, realize reliable clutch effect, the not obstruction of the roller that can have been damaged or flat spring is so the present invention can effectively 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.
