Title:
MOTIVE POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JPS5617742
Kind Code:
A
Abstract:
A hydraulic retarder in conjunction with a multi-speed power transmission that finds particular utility for off-highway trucks. The hydraulic retarder is continuously filled with oil and is positioned in series with a hydraulically actuated friction type clutch. The retarder remains filled at all times and consequently there is no loss of time in filling or dumping the retarder when it is desired to utilize its retarding action by engaging its clutch. This "instantaneous" reaction to engagement and disengagement of the retarder makes it possible to use this retarder in certain automatic modes where conventional dump and fill hydrodynamic retardation devices are so slow to react as to be difficult to apply. This retarder has clutched engagement and disengagement. The torque capacity versus speed is varied through cavity pressure control.
