Abstract

The invention discloses a one-way clutch compact in structure. The one-way clutch comprises a rolling bearing. The rolling bearing comprises an inner ring (02), an outer ring (01), a cage (46) and rolling bodies (04). The rolling bodies and ellipsoidal rollers (86) inside the cage are distributed in a staggered mode, the ellipsoidal rollers are arranged in an inclined mode, the two ends of the long axis of each ellipsoidal roller make contact with the inner ring and the outer ring respectively, open slots are formed in the positions, making contact with the inner ring, of the ellipsoidal rollers, and springs (89) are arranged inside the open slots and connected with the ellipsoidal rollers. When the ellipsoidal rollers move to the springs, the one-way clutch rotates freely, and when the ellipsoidal rollers move away from the springs, the inner ring and the outer ring are locked to lock the one-way clutch. The one-way clutch compact in structure has the advantages that the one-way rollers are moved into the rolling bearing and connected with the cage and the rolling bodies of the rolling bearing into a whole, in this way, finish machining and surface treatment do not need to be performed on the inner circle of a shell, the number of technological processes is reduced, and the cost is lowered; the material and structural design of original one-way rollers are changed, the structure is compact, and the using cost is lowered.

Description

technical field

[0001] The invention relates to a one-way clutch, in particular to a compact one-way clutch. Background technique

[0002] The emergence of automatic transmission cars has greatly satisfied the user's requirements for car driving pleasure and driving simplification. The core component of automatic transmission cars is the automatic transmission. The automatic shifting function of the automatic transmission is realized through the joint action of the hydraulic control system and the planetary gear transmission system, and the essential key component in the planetary gear transmission system is the one-way clutch. The one-way clutch makes the gear or wheel sleeve connected to it only rotate in one direction, so as to realize the needs of automatic gear shifting. The existing one-way clutch includes the inner circle of the housing (the part that cooperates with the clutch), which requires fine grinding and surface treatment; the one-way roller assembly, includi...
