Title:
THREE BALL PIN-TYPE COUPLING AND STEERING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2022/021081
Kind Code:
A1
Abstract:
A three ball pin-type coupling, comprising a first connector (M) and a second connector (N) which are non-rotatably connected. The first connector (M) comprises a three shaft pin assembly (10), raceway assemblies (20) and a cage assembly (30). The three shaft pin assembly (10) comprises a shaft (11) and three ball rings (13) which surround the shaft (11) and are arranged at intervals in the circumferential direction of the shaft (11). There are three raceway assemblies (20). Each ball ring (13) is connected to a raceway assembly (20). The cage assembly (30) defines the position of the raceway assemblies (20) in the circumferential direction. The raceway assemblies (20) can provide elastic force between the ball ring (13) and the cage assembly (30). When the ball ring (13) displaces relative to the cage assembly (30) in the circumferential direction, the two sides of the raceway assemblies (20) in the circumferential direction remain abutted against the cage assembly (30).
A steering mechanism is also provided.
