The utility model is composed of a mechanism for controlling the engagement and the disengagement of two teeth gears, a buffer device and a locking device, wherein, the mechanism for controlling the engagement and the disengagement of two teeth gears is composed of a transmission member (1), a teeth gear engaged member (14), a flexing member (10) arranged between the circumferential axial direction of the teeth gear engaged member, a pressure spring (12) and a frictional damping member (15); the buffer device is composed of a preloaded pressure spring (6); the lock device is composed of the side surface of a spiral convexity on the inner wall of a transmission sleeve barrel (9) and the corresponding side surface of a spiral groove on the outer surface of the teeth gear engaged member (14). The utility model is used for the occasions having overrun transmission. When the clutch is arranged between the transmission sleeve barrel (9) and a transmission shaft (5), the utility model can be used as a sliding device for a motor vehicle.
Description
The utility model relates to a kind of overrunning clutch, especially the tooth embedding engagement overdrive clutch of being made up of tooth embedding engaging member, pressure spring, axle.
It is exactly this structure that a kind of tooth embedding engagement overdrive clutch is arranged at present.Concrete structure is: the tooth embedding engaging member that is oblique triangle by two tooth forms is installed on the axle relatively, and pressure spring applies axial pressure to the outside of one tooth embedding engaging member.When one tooth embedding engaging member rotates on the one hand, can drive another tooth embedding engaging member and rotate, but when other direction rotates owing to the axial force that produces between two tooth embeddings is skidded the tooth embedding.The subject matter that this tooth embedding engagement overdrive clutch exists is: noise is arranged, impact is arranged, can only be used for the little occasion of slip.
Task of the present utility model provides a kind of noiseless, does not have the tooth embedding engagement overdrive clutch that impacts, can be used for the big occasion of slip.
For finishing above-mentioned task, scheme of the present utility model is: it has driving component and transmission shaft, and the driving component transmission shaft is same axis and is connected.Increasing by a frictional damping part on the transmission shaft and be between another tooth embedding engaging member of a tooth embedding engaging member with pressure spring, the frictional damping part is between the tooth embedding engaging member pressure spring, between the frictional damping part one tooth embedding engaging member friction pair is arranged.The driving component transmission shafts between thrust ring back of the body cap is arranged.Between another tooth embedding engaging member thrust ring, axial clearance is arranged when surmounting transmission.Between another tooth embedding engaging member transmission shaft, the preload pressure spring is arranged, the pretightening force of pressure spring greater than the pressure spring between the two tooth embedding engaging members the tooth embedding in conjunction with the time pressure.It has drive socket, and drive socket one end connects with driving component, and the other end connects with flange plate, and the flange plate center is porose.The inwall of drive socket has internal spiral, is positioned on the outer surface of a tooth embedding engaging member with the external spiral of internal spiral tabling, and spiral salient can be made circle swing in helical groove.Be provided with flex member at the circumference of driving component one tooth embedding engaging member between axially, flex member can free bend, flex member and driving component one tooth embedding engaging member be connected to flexible connection.Working principle of the present utility model is: when driving component is input and rotating speed during less than the transmission shaft rotating speed, part helical groove one side is nibbled in the tooth embedding that reclines of drive socket spiral salient one side, this moment is around bent part and shaft axis coincidence and parallel, break away from fully between two tooth embeddings, trackslip between the frictional damping part one tooth embedding engaging member.When driving component is input and rotating speed during greater than the transmission shaft rotating speed, because the frictional force of friction pair just can make flex member become a helix angle with shaft axis.The axial position that increases gradually between the driving component one tooth embedding engaging member along with helix angle dwindles gradually, and the compression pressure spring is until a tooth embedding engaging member and complete combination of another tooth embedding engaging member.The opposite side of the spiral salient of drive socket also contacts with the opposite side of a tooth embedding engaging member helical groove at this moment.Another tooth embedding engaging member begins to compress the preload pressure spring till another tooth embedding engaging member and thrust ring axially do not have the gap.At this moment the another side of the another side of drive socket spiral salient and a tooth embedding engaging member helical groove compresses fully and since between them the axial locking power that produces greater than two tooth embeddings in conjunction with the time the axial tearaway load that produces, so reached the locking purpose.Driving component rotates together by drive socket and two tooth embedding engaging members drive transmission shaft like this.The utility model also can be with transmission shaft as importing driving component as output.This is a kind of tooth embedding engagement overdrive clutch that can only do the mono-directional overrun transmission.
Between the drive socket transmission shaft of above-mentioned tooth embedding engagement overdrive clutch, be added with clutch, make this clutch in conjunction with the time, driving component and transmission shaft are combined into one by drive socket and this clutch, can make two-way nothing surmount transmission this moment.Make this throw-out-of clutch then can do the mono-directional overrun transmission, another embodiment of this tooth embedding engagement overdrive clutch can be used as the glider of motor vehicle.
The utility model tooth embedding engagement overdrive clutch since when surmounting transmission two tooth embeddings break away from fully so noiseless.Because flex member is the flexible buffer function that adds the preload pressure spring so do not impact in conjunction with having.Again since flex member when low pitch angle very two tooth embeddings just being forced to property contact and enter combination, can be used for the big occasion of slip in conjunction with in time dying.The utility model has been finished the foregoing invention task like this.
