The invention provides a single-gear engaging mechanism for a motorcycle and belongs to the technical field of machinery. According to the single-gear engaging mechanism, the technical problems that noises are loud during engaging in the prior art are solved. The single-gear engaging mechanism comprises a ratchet I and a ratchet II, wherein a clamping groove is formed in the inner end face of the ratchet II; a boss is arranged on the inner end face of the ratchet I. The single-gear engaging mechanism further comprises a shift fork rod; the outer end of the shift fork rod is connected with the side wall of the ratchet I. The single-gear engaging mechanism is characterized in that a through hole coaxial with the ratchet I is formed in the inner end of the shift fork rod. The single-gear engaging mechanism also comprises a screw rod; one end of the screw rod penetrates through the through hole and is connected with the output shaft of a motor; an elastic part is sleeved on the screw rod; two ends of the elastic part are connected with the upper side of the inner end of the shift fork rod and the output shaft of the motor; a screw rod sleeve is in threaded connection with the screw rod; one end of the screw rod sleeve is propped against the lower side of the inner end of the shift fork rod; a limiting structure for circumferentially positioning the screw rod sleeve is fixedly connected to the outer side wall of the screw rod sleeve. According to the single-gear engaging mechanism, noises during engaging are effectively reduced.
Description
technical field [0001] The invention belongs to the technical field of machinery and relates to a single-gear gear-engaging mechanism in a motorcycle. Background technique [0002] Commonly used separation mechanisms include diaphragm clutches, friction plate clutches and traditional multi-gear gearing mechanisms. But now such as in the drive axle of hybrid power, there are generally two motors. According to the change of working conditions, it is necessary to separate and connect the single motor or the input end of the engine separately. In this environment, the traditional multi-gear Gear-engaging mechanism, or diaphragm clutch or friction plate clutch. [0003] my country's patent CN103527658A discloses a diaphragm type automobile clutch, which includes a pressure plate, a clutch cover, a diaphragm, an inner support ring and an outer support ring, and several diaphragm rivets uniformly distributed in the circumferential direction, the left end of the diaphragm rivet The...
