Abstract
The present invention relates to a kind of overrunning clutch, it is characterized in that: form by driving part, driven member and clutch part, described clutch part is made up of a ring support and Engaging-and-disengaging bearing, on ring support, be provided with several bearing grooves equably, Engaging-and-disengaging bearing is contained in the bearing groove, one of them is contained in the inside of ring support described driving part and driven member, another then is socketed in the outside of ring support, side at the corresponding driven member of Engaging-and-disengaging bearing is provided with the clutch projection, and is provided with interface arrangment between Engaging-and-disengaging bearing and driving part.The present invention has simple in structure, and the idle running stroke is very short, the nonabradable characteristics of each parts.
Description
Technical field
The present invention relates to a kind of clutch, specifically is the overrunning clutch of a kind of use on electric motor car or motorcycle.
Background technique
Motorcycle or electric motor car gear motor when closing electric switch or throttle can play braking action at present, but because the inertia of vehicle body makes car move on, motor are had certain damage, cause engine life shorter, and be fragile, and fuel consumption is big; Also have at present in the gear-box of motorcycle or clutch is set in the electric vehicle hub, but these present clutches to exist noise bigger, clutch idle running stroke is longer from be inverted to the transfer process of just changeing, influence the effect that clutch uses, owing between the longer clutch inner body of idle running spacing, impact bigger mutually, each inner parts are fragile, directly have influence on the working life of clutch.
Summary of the invention
The object of the present invention is to provide a kind of overrunning clutch, have simple in structure, idle running stroke very short, the nonabradable characteristics of each parts.
For achieving the above object by the following technical solutions:
A kind of overrunning clutch, it is characterized in that: form by driving part, driven member and clutch part, described clutch part is made up of a ring support and Engaging-and-disengaging bearing, on ring support, be provided with several bearing grooves equably, Engaging-and-disengaging bearing is contained in the bearing groove, one of them is contained in the inside of ring support described driving part and driven member, another then is socketed in the outside of ring support, side at the corresponding driven member of Engaging-and-disengaging bearing is provided with the clutch projection, and is provided with interface arrangment between Engaging-and-disengaging bearing and driving part.
Described interface arrangment is equipped with a shackle member for all to offer buckling groove on each Engaging-and-disengaging bearing and driving part opposite position in buckling groove.
Described buckling groove runs through the Engaging-and-disengaging bearing top and the bottom, and described shackle member is an elongated roller.
The be arranged top of Engaging-and-disengaging bearing and driving part of described buckling groove, described shackle member is a spin.
Driving part is connected with the power unit of vehicle during use of the present invention, driven member is connected with the parts of driving, when powered vehicle is advanced, when power unit drives driving part, driving part just changes with respect to ring support and driven member, be provided with interface arrangment between the Engaging-and-disengaging bearing of driving part and clutch part, thereby Engaging-and-disengaging bearing produces counter-rotating makes the clutch projection on the Engaging-and-disengaging bearing contact also stuck with driven member, with driving part, clutch part and driven member connect into an integral body, and then powered vehicle is advanced, and when the rotating speed of driven member during greater than the driving part rotating speed, this moment, driving part reversed with respect to driven member, thereby Engaging-and-disengaging bearing is just changeing and makes clutch projection and driven member be separated; The present invention is provided with interface arrangment between driving part and Engaging-and-disengaging bearing, drive in the driven member process at driving part, the Engaging-and-disengaging bearing speed of response is fast, the idle running stroke just shortens naturally greatly, driven member and Engaging-and-disengaging bearing in conjunction with the time be to interact along the tangent direction of clutch projection, impact between each parts is reduced to minimum, greatly reduces in the working procedure, prolonged the operating life of parts the damage of clutch inner member.
Description of drawings
Fig. 1, structural representation of the present invention;
Fig. 2, perspective exploded view of the present invention;
The perspective exploded view of Fig. 3, another mode of execution of the present invention.
Embodiment
Shown in Fig. 1-2, a kind of overrunning clutch, by driving part 1, driven member 2 and clutch part 3 are formed, described clutch part 3 is made up of a ring support 31 and Engaging-and-disengaging bearing 32, on ring support 31, be provided with several bearing grooves 33 equably, Engaging-and-disengaging bearing 32 is contained in the bearing groove 33, described driving part 1 is contained in the inside of ring support 31, driven member 2 is socketed in the outside of ring support 31, side at Engaging-and-disengaging bearing 32 corresponding driven members 2 is provided with clutch projection 34, on each Engaging-and-disengaging bearing 32 and driving part 1 opposite position, all offer buckling groove 11,35, buckling groove 35 runs through Engaging-and-disengaging bearing 32 top and the bottom, at buckling groove 11, be equipped with a roller 4 in 35.
When the present invention works, the power unit of vehicle drives driving part and rotates, driving part just changes with respect to driven member and ring support this moment, and Engaging-and-disengaging bearing produces reverse rotation, make clutch projection and the mutual clamping of driven member on the Engaging-and-disengaging bearing, just change together thereby driving part drives driven member; And when the driven member rotating speed is higher than driving part, just be equivalent to driving part this moment with respect to driven member and ring support counter-rotating, Engaging-and-disengaging bearing then can produce the forward rotation, make the clutch projection on the Engaging-and-disengaging bearing break away from driven member, driven member and driving part are separated from each other, and this moment, vehicle was in idling conditions to the not damage of inner power unit; The present invention at Engaging-and-disengaging bearing and driven member when being separated to bonding state, the tangent direction of the clutch projection of driven member inboard and Engaging-and-disengaging bearing outside collides, this combination has at utmost reduced the damage of collision to each parts, guarantee the reliability of inner each parts work, Engaging-and-disengaging bearing of the present invention in addition is transient response, so it is short at the Cheng Feichang that changes one's profession in conjunction with space-time, further alleviated internal impact intensity, thereby also reduced the noise when working, promoted the overall performance of clutch.
As shown in Figure 3, the present invention also can be opened in buckling groove 11,35 top of Engaging-and-disengaging bearing 32 and driving part 1, and described shackle member is a spin 5, spin 5 with respect to roller 4 slick and sly more, moment can not occur the metal fatigue phenomenon such as blocks, and makes that the using effect of clutch is better.
