摘要： In a drive coupling unit suitable for use in an four-wheel drive unit for motor vehicles of the type wherein a torque is transmitted via a fluid pressure produced depending on a difference in rotational speed between two rotating shafts, each working fluid supply passage and a corresponding check valve disposed therein are arranged to interconnect one of two intake/discharge ports in each respective pump chamber with a tank in which a working fluid is retained. With this construction, an improved response characteristic of the check valves and a substantial reduction of the overall size of the drive coupling unit can be attained.

摘要： A hydraulic transmission coupling apparatus which is used instead of a center differential or a viscous coupling being usually mounted between a front wheel drive shaft and a rear wheel drive shaft of a four-wheel drive vehicle, and transmits driving force existing between the two shafts. The hydraulic transmission coupling apparatus is provided with a vane-type hydraulic pump which generates hydraulic pressure corresponding to a relative rotation speed difference of the two drive shafts and a variable throttle valve being disposed in the passage connecting a discharge port of the hydraulic pump with a tank, whose opening area varies according to the hydraulic pressure generated by the hydraulic pump, thereby driving force to be transmitted being increased or decreased steeply as the rotation speed difference becomes larger.

摘要： A structure in which a reservoir is supported by a bracket. The bracket has a side plate facing the external circumference of the reservoir and a bottom plate facing the bottom of the reservoir. An insert fitting portion formed onto the reservoir is fitted from above into a receiver fitting portion formed onto the side plate. A lock member is supported by the side plate like a cantilever at the upper edge of an opening formed on the side plate. A catch portion formed on the reservoir forces the lock member to displace elastically so that the lock member recedes from the reservoir in the course of fitting of the insert fitting portion into the receiver fitting portion. The side plate is elastically deformable in company with the elastic displacement of the lock member. When the fitting operation is completed, the lock member comes close to the reservoir to recover its original position and is placed on the top of the catch portion to prevent the upward dismount of the reservoir out of the bracket. An auxiliary receiver fitting portion is formed onto the bottom plate, and an auxiliary insert fitting portion is formed onto the reservoir, and thus, the reservoir is supported by the bracket at two support areas.
摘要翻译：储液器由支架支撑的结构。支架具有面向储存器的外周的侧板和面向储存器底部的底板。形成在储存器上的插入装配部分从上方装配到形成在侧板上的接收器配合部分中。在侧板上形成的开口的上边缘处，锁定构件像悬臂一样由侧板支撑。形成在储存器上的卡扣部分迫使锁定件弹性移位，使得锁定件在插入装配部分嵌入接收器配件部分的过程中从储存器中退出。侧板随着锁定构件的弹性位移而弹性变形。当装配操作完成时，锁定构件靠近贮存器以恢复其原始位置并且被放置在捕获部分的顶部上，以防止储存器向上卸下支架。辅助接收装置部分形成在底板上，并且辅助插入装配部分形成在储存器上，因此储存器由支架在两个支撑区域支撑。
