Abstract
The utility model discloses an overrun clutch for an electric bicycle and an electro-tricycle, and belongs to the clutch field. The overrun clutch comprises an outer ring; an inner ring is arranged in the outer ring; an one-way stop device is arranged between the inner ring and the outer ring; a spline structure is arranged on the outer surface of the outer ring; the one-way stop device is provided with a pin roller and a reset device; the pin roller is arranged in a roller path formed between an outer ring-type cavity and the inner ring; one end of the reset device contacts with the outer ring-type cavity, and the other end contacts with the pin roller; bearings are arranged on two ends of the one-way stop device; a pad sheet is arranged between the one-way stop device and each of the bearings; and clamp springs are used for positioning the bearings on the two ends. According to the utility model, axial and radial ran-out is reduced so that structure of the clutch is more stable, and the bearings are additionally arranged, so precision of operation of the inner ring, the outer rings and the one-way stop device is effectively ensured, positioning precision of the clutch is ensured, the clutch is allowed to operate stably, and service lifetime of the clutch is prolonged.
Description
Technical field
The utility model relates to clutch, more particularly, relates to a kind of electric bicycle, the automobile-used free wheel device of electric three-wheel.
Background technique
Clutch is divided into embedded clutch, engagement sleeve and automatic clutch, in automatic clutch, there is a kind of free wheel device, 2 kinds of structures below the free wheel device using on electric motor car, electro-tricycle mainly exists: mainly being formed by star-wheel, outer ring, roller, spring compressor and spring of (1) this kind of overrunning clutch, outer ring is made a gear conventionally, built-in star-wheel, in several breach of star-wheel, a roller is respectively housed, and each roller is pushed in the raceway that breach formed of outer ring and star-wheel by spring, spring compressor again; (2) mainly being formed by inner ring, outer ring, roller, spring compressor and spring of this kind of overrunning clutch, inner ring is made internal gear conventionally, external outer ring, a roller is respectively housed in several breach of outer ring, and each roller is pushed in the raceway that breach formed of inner ring and outer ring by spring, spring compressor again.The play of such free wheel device is large, and precision is limited.
Summary of the invention
The utility model is greatly further studied for the play of the clutch in above-mentioned technology.
Realize the technical solution of the utility model as follows:
A kind of electric bicycle of the present utility model, the automobile-used free wheel device of electric three-wheel, there is outer ring, in outer ring, be provided with inner ring, between inner ring and outer ring, be provided with unidirectional limit stoper, the outer surface of outer ring is set to spline structure, unidirectional limit stoper has roller and resetting means, roller is arranged in the raceway of outer ring die cavity and inner ring formation, resetting means one end contacts with outer ring die cavity, the other end and roller-contact, unidirectional limit stoper two ends are provided with bearing, and respectively assemble pad between unidirectional limit stoper and bearing, adopt the bearing location that jump ring is two ends.
Further, described resetting means is Z-shaped spring.
Further, the interior surface of contact of described inner ring is through hole or spline or worm structure.
The beneficial effects of the utility model are, the utility model adopts above scheme, unidirectional limit stoper two ends are provided with bearing, have prevented that axial-radial from beating, and make the structure of clutch more stable, each assembling pad between unidirectional limit stoper and bearing, to adopt jump ring be two ends bearing location, this arranges effective running accuracy that has ensured Internal and external cycle, unidirectional limit stoper, has ensured the positioning precision of clutch, make clutch smooth running, extended the working life of clutch.
