摘要:
A power transmission including a hydrodynamic torque converter and a modulated clutch, having a hydraulic control system for limiting the amount of torque which is capable of being applied to the wheels of a vehicle or the like. The control system includes an output driven pump which produces a signal flow proportional to its speed, and this signal is conducted to a variable orifice torque limiter valve. The torque limiter valve in turn controls the available fluid pressure which is conducted to the modulatable clutch, which clutch in turn determines the power output. Thus the output speed of the transmission is ''''read'''' and through a control system the output speed is controlled to limit the output torque.
摘要:
Apparatus and a method for utilizing hydraulic pressure to separate a tapered, keyless connection between two members, for example between a shaft and a gear press-fit thereon. The invention includes the use of a threaded bolt means for building up the hydraulic pressure and furthermore contemplates the use of Teflon tape around the bolt means so as to seal the bolt means at its threaded aperture to enable the application of sufficient hydraulic force to cause the parts to be separated. Fluid such as grease or oil is placed in passageways in the parts and when the pressure is applied by tightening the threaded member, the parts are forcibly separated and to prevent them from flying apart in a hazardous manner, other bolt means which connect the parts are backed-off partially so as to stop the separating movement between the parts after the tapered joint has been broken.
