Title:
SHIFT MECHANISM OF HYDRAULIC TRANSMISSION
Document Type and Number:
Japanese Patent JP2669991
Kind Code:
B2
Abstract:
PURPOSE: To prevent the driven turn of a distributing ring by allowing the revolution direction of a valve body and the shift direction of an oil pressure distributing ring to coincide with each other and installing a stopper member which is engaged in contact with the shift member, at a prescribed shift position from the shift direction side for the shift member.
CONSTITUTION: A distributing ring 29 which sliding-contacts a valve body 3 which integrally revolves with a hydraulic motor M and select advance and retreat by the eccentric revolution is installed The shift direction of the distributing ring 29 is allowed to coincide with the revolution direction of the hydraulic motor M, and stopper members 87c and 87d which are engaged in contact with a proper shift member, e.g. a shift gear 60, at a proper shift position, opposed from the shift direction side of the shift gear 60 are installed. Accordingly, the driven turn of the distribution ring 29 can be prevented with a simple structure, without applying the precision work on the distributing ring 29 and a distributing ring supporting shaft 25, and at the same time, the prescribed distribution timing can be maintained, and the power transmission efficiency can be improved.
