Abstract
The utility model discloses an overrunning coupler of an electric starting motorbike, comprising a driven gear, wherein the outside of the driven gear is provided with a transmission post; the outside of the transmission post is sheathed with a ring-shaped base; the inner hole wall of the ring-shaped base is evenly provided with a plurality of notches; the thickness of the inner side walls of the notches are different; the notch is internally provided with a cylinder; the inner side of the cylinder pushes against a spring; and when the spring pushes the cylinder to the thicker end of the inner side wall of the notch, the cylinder and the transmission post are clamped and clutched into a whole. The overrunning coupler has simple and compact structure, light weight, large torque, reliable driving force and convenient and flexible installation.
Description
Technical field
The utility model belongs to clutch, specifically is the free wheel device that a kind of electricity starts motorcycle.
Background technique
It is two kinds of out star wheel and star-wheels that roller-type overrunning clutch is divided into out star wheel according to yoke in it (star-wheel) position difference, and so-called yoke is meant the conjugate planes of cylinder and cylindrical hole, and star-wheel is the part with the groove that holds roller.For the ease of processing with guarantee machining accuracy, being widely adopted of star-wheel formula.Press the shape difference of star-wheel working surface, can be divided into three kinds on plane, logarithm helicoid type and eccentric circle cylinder type etc. again.Wherein plane processing is simple, be widely used, but its wedge feeler do not change with different change of contact position with the roller wearing and tearing, but processing is difficult; The processing complexity of eccentric circle cylinder, usability, life-span all occupy between the former two.
The model utility content
The purpose of this utility model provides the free wheel device that a kind of electricity starts motorcycle, and is simple and compact for structure, in light weight, torque is big, and driving force is reliable, easy for installation flexibly.
The technical solution of the utility model is as follows:
Electricity starts the free wheel device of motorcycle, include driven gear, the outside of driven gear has and takes off post, be set with annular seating outside described the taking off post, evenly have several breach on the inner hole wall of annular seating, the madial wall thickness difference of breach, be equipped with cylindrical body in the breach, cylindrical inboard has pushed against spring, when described spring is shifted cylindrical body the madial wall thicker end of breach onto, cylindrical body will take off post the engaging and obvolvent be one.
Have containing groove on the annular seating in the described cylindrical body outside, be provided with bearing pin in the containing groove, an end of bearing pin lean with cylindrical sidewall on, the other end by described spring roof pressure.
The arranged outside that takes off post of the present utility model has a plurality of cylindrical bodys, guaranteed torque reliable and stable of transmission, and the utility model is simple and compact for structure, and is in light weight, torque is big, and driving force is reliable, easy for installation flexibly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, electricity starts the free wheel device of motorcycle, include driven gear, the outside of driven gear has and takes off post 2, the 2 outer annular seatings 3 that are set with take off post, evenly have several breach 4 on the inner hole wall of annular seating 3, the madial wall thickness difference of breach 4, be equipped with cylindrical body 5 in the breach 4, have containing groove on the annular seating 3 in cylindrical body 5 outsides, be provided with bearing pin 6 in the containing groove, one end of bearing pin 6 leans on the sidewall with cylindrical body 5, the other end by spring 1 roof pressure, when spring 1 is shifted cylindrical body 5 the madial wall thicker end of breach 4 onto, cylindrical body 5 will take off post 2 the engaging and obvolvent be one.
