overrunning clutch

Abstract

The invention overcomes the defects that early failure and shorter service life of the existing overrun clutch are caused by proneness of a folding spring to wearing, and relates to an overrun clutch comprising an inner cam, a left baffle and a right baffle. A plurality of raceways are evenly distributed on the peripheral surface of the inner cam. Opposing sides of the left baffle and / or the right baffle are provided with barrier parts extending over the raceways, and each barrier part is located at the connection of each two adjacent raceways. The rear end of each folding spring is provided with a bent part extending backwards, and the lower portion of each barrier part is provided with a clamp part for clamping the bent part of the folding spring. The folding springs of the overrun clutch are fixed through the bent parts, the upper and lower portions of each folding spring are suspended, and accordingly no wearing occurs, the folding springs are effectively protected from damage due to frictional interference caused by top-bottom contact and average fault-free service life of the overrun clutch is prolonged.

Description

technical field [0001] The invention relates to a clutch, in particular to an overrunning clutch applied to a twin-turbine hydraulic torque converter. Background technique [0002] At present, 80% of domestic loaders use twin-turbo torque converters. The twin-turbine torque converters work together with the overrunning clutch to input power to the gearbox, which can automatically switch between high-speed light loads and low-speed heavy loads. , Improve work efficiency and reduce labor intensity of drivers. High-speed light load mainly refers to the process of the loader transporting materials or traveling, such as the loader empty bucket or carrying goods, at this time the driving speed is faster, but the traveling resistance is small; low-speed heavy load mainly refers to the loader shoveling materials, here When the bucket is inserted into the material, the forward resistance is huge, but the forward speed is low. [0003] The existing non-cage overrunning clutch is mai...

Problems solved by technology

[0006] The purpose of the present invention is to provide an overrunning clutch with high reliability and long service life, which is not easy to wear and has a high reliability, in view of the problems that the folding spring of the existing overrunning clutch is easy to wear and cause early failure and short life.
