Multimode Clutch

Abstract

The invention provides a multi-mode clutch. A plurality of receding grooves which are uniformly distributed are formed in the inner side surface of an outer ring, two radial through holes are formed in the bottoms of the receding grooves, positioning seats provided with springs are arranged in the radial through holes, and axial through grooves with cylindrical structures are symmetrically formedin the two sides, parallel to the axial direction, of the receding grooves; blocking blocks are in clamping connection with the axial through grooves in a matched mode, the sides, facing the positioning seats, of the blocking blocks are in contact with the positioning seats, a limiting groove is formed in one end surface of the outer ring, a plurality of uniformly distributed windows are formed inthe outer side surface of a control ring, and a driving block which protrudes outwards is arranged on one end surface of the control ring in parallel; and the outer ring, the control ring and an inner ring are sequentially sleeved together in a clearance mode from outside to inside, the windows of the control ring are in one-to-one correspondence with the receding grooves of the outer ring, and the driving block of the control ring is arranged in the limiting groove of the outer ring. According to the multi-mode clutch, the structure is simple, the locking direction of the inner ring is adjusted to enable the multi-mode clutch to have three working modes, and meanwhile, the slippage of the inner ring can be avoided.

Description

technical field [0001] The invention relates to a multimode clutch. Background technique [0002] At present, in a hybrid transmission or an automatic transmission of an automobile, a multi-mode clutch is often required to prevent or allow a certain part in the transmission to rotate. At present, multi-mode clutches in engineering applications mainly include rollers, roller retaining springs, control rings, inner rings, and outer rings. The relative position between them depends on the friction force when the rollers and the inner ring and the outer ring are in contact at the same time to prevent or allow the inner ring to rotate. The locking torque of the multi-mode clutch with this structure is relatively low, and there is a risk of inner ring slipping; when the roller is in the neutral position and the inner ring can rotate clockwise and counterclockwise, due to the friction between The deflection of the inner ring caused by force and external factors makes there is a r...

Problems solved by technology

The locking torque of the multi-mode clutch with this structure is relatively low, and there is a risk of inner ring slipping; when the roller is in the neutral position and the inner ring can rotate clockwise and counterclockwise, due to the friction between The deflection of the inner ring caused by force and external factors makes there is a risk that the rollers will suddenly enter the locking position and cause the multi-mode clutch to fail
