Abstract
The utility model discloses an overrunning clutch, which comprises a sleeve-shaped retainer which is arranged at the inner side of an external star wheel, wherein pockets which penetrate through the inner and outer surfaces of the retainer and correspond to grooves are arranged on the retainer, and rolling needles are distributed in the pockets; the pockets close to one side of the positioning surface of the retainer are provided with protective grooves, and the protective grooves are used for placing springs; and bulges are convexly arranged at the two axial sides of each pocket on the outer surface of the retainer, and the positioning surface of the retainer for positioning and matching the budges is arranged at one side of a wedge-shaped working surface away from an arc surface on the bottom of each groove. When the overrunning clutch is in a working state, the rolling needles are always kept in the pockets, and the springs are always kept in the protective grooves, so that the work stability is greatly improved.
Description
Technical field
The utility model relates to a kind of automobile current generator input end free wheel device, belongs to the Clutch Technology field.
Background technique
Automobile is in running, the rotor rotation that engine rotation drives generator provides needed electric power for automobile, when the unexpected step-down of rotating speed of motor, and the also corresponding step-down suddenly of the rotor of generator, cause infringement easily, reduce the life-span of motor generator.
Application number is that 200920128132.7 patent has been announced a kind of free wheel device, comprise out star wheel, on the inwall of out star wheel, have by the equally distributed groove of circumference, and needle roller and spring are housed in each groove, described groove is a dovetail groove, and the bottom land of this groove is linked to each other with arc surface by sphenoid surface and forms.Though it is simple and convenient that the free wheel device of this structure is processed, and reduced cost, the working stability of needle roller and spring is relatively poor in the groove, and then has influence on the service behaviour of clutch.
The model utility content
The purpose of this utility model provides a kind of free wheel device, in order to the needle roller in the solution free wheel device and the relatively poor problem of working stability of spring.
For addressing the above problem; the utility model adopts following technological scheme: a kind of free wheel device; comprise out star wheel and needle roller; have on the inwall of out star wheel by circumferencial direction evenly that arrange with the groove corresponding setting of each needle roller; the bottom land of described groove comprises the wedge shape working surface and the arc surface of tangent connection; this clutch also comprises the retainer of the round shell-like that is arranged on the out star wheel inboard; offer the pocket hole corresponding that connects the retainer inner and outer surface on the described retainer with described groove; described needle roller is arranged in the pocket hole; the pocket hole offers the protection groove near retainer locating face one side; described protection groove is used to arrange spring; axial both sides with each pocket hole on the outer surface of described retainer convex with projection, are provided with the side away from arc surface of wedge shape working surface on the bottom land of described groove to be used for the retainer locating face that cooperates with described projection location.
Described retainer locating face is located in the described groove, and is connected with the wedge shape working surface is tangent.
The angle of wedge between needle roller and the wedge shape working surface is 9 °.
Described retainer inboard is provided with inner ring.
Adopt the free wheel device of the out star wheel, retainer and the inner ring that set gradually from outside to inside; retainer relies on the projection on its outer surface to cooperate with retainer locating face location; needle roller is arranged in the pocket hole of offering on the retainer, and spring is arranged in the protection groove of offering near retainer locating face one side in the pocket hole.When free wheel device is in the transmitting torque state, rely on the angle of wedge of wedge shape working surface and needle roller, needle roller and out star wheel and inner ring wedging; When free wheel device is in when surmounting state, rely on needle roller and out star wheel and inner ring to separate wedge, no longer transmitting torque.In the in running order process of free wheel device, needle roller remains in the pocket hole, spring remains in the protection groove, and its working stability is greatly improved.
