The invention relates to an overrunning clutch, in particular to an overrunning clutch for a motor of an electric bicycle. The overrunning clutch of the electric bicycle is characterized by comprising an outer ring, an inner ring, as well as a clutch assembly and a rolling steel ball assembly which are arranged between the outer ring and the inner ring, wherein the clutch assembly and the rolling steel ball assembly comprise a retainer, wedge rollers, thrust springs, a wedge sealing cover plate, steel balls and a steel ball sealing cover plate; the wedge rollers and the steel balls are arranged on the two sides of the retainer respectively; the thrust springs are arranged on the retainer and connected with the wedge rollers; the wedge sealing cover plate is connected with the side surface of the retainer and used for fixing and compressing the wedge rollers; the steel ball sealing cover plate is used for compressing the steel balls; the outer ring is provided with a plurality of locating grooves pressed into an inner wall of a motor housing; and an inner wall of the inner ring is toothed and is engaged with a planet gear of the motor. The overrunning clutch is more compact in structure; the technology is simplified; the cost is saved; the transmission efficiency is higher; and perfect combination of manual driving and electric driving is achieved.
Description
technical field [0001] The invention relates to an overrunning clutch, in particular to an overrunning clutch used on an electric vehicle motor. Background technique [0002] With the concept of low-carbon energy saving and environmental protection gradually becoming popular, electric vehicles, as an environmentally friendly and energy-saving means of transportation, have become the travel choice of more and more people. The electric vehicle industry is developing rapidly, and the driving mode of electric vehicles has also undergone certain changes. , from the original hub motor drive to the drive with overrunning clutch motor, on the one hand, the structural layout of the electric bicycle is more reasonable, and the mechanical conversion efficiency is improved; safety. The present invention is another improvement on the basis of the general electric vehicle overrunning clutch. The inner hole of the existing overrunning clutch is connected with the key pin of the motor sha...
