Title: A torque converter power transmission having regulating valve means
IPC: F16H45/00
Filed: 1970-12-30
Abstract: 1293475 Clutch control TWIN DISC Inc 30 Dec 1970 [5 Jan 1970] 61882/70 Heading F2L In a transmission system for a motor vehicle wherein drive is transmitted through a hydraulically operated continuously slipping friction clutch CL, a torque converter TC and a change speed gear, a pressure regulating valve E which normally maintain the supply pressure 10 at a predetermined value reduces the supply pressure and thus the clutch engaging pressure during a shift from forward to reverse ratio or vice versa. Friction clutch.-The clutch CL may be of the type described in Specification 1,133,698 wherein a control valve 16 varies the pressure supply to a clutch actuating chamber 7 to maintain the clutch output speed constant for a predetermined value of a control pressure 14. A variation in the control pressure 14 adjust the output speed of the clutch CL which automatically maintains its output speed proportional to the control pressure. Fluid system components.-The output pressure of a pump 9 is regulated by the valve E. The regulated supply pressure is supplied to a forward-reverse valve FR; through a manually controlled modulating valve D to the clutch control pressure line 14; and through a line 10 to the clutch actuating chamber 7. Exhaust fluid from the regulating valve E passes through the plates of the clutch CL to the torque converter working circuit. Exhaust fluid from the torque converter is maintained at a predetermined pressure by a relief valve 34. Operation.-The regulator valve E is biased left by a spring 21 reacting against a loading plunger E1 which is normally held in the position shown by pressure fluid from the forward-reverse valve FR. During a forwardreverse ratio shift the valve FR vents the loading pressure on the plunger E1 which thus moves right and permits the valve E to reduce the supply pressure and thus the clutch engagement. On completion of ratio shift liquid pressure acting on the plunger E1 is restored slowly through a restriction E3. The supply pressure and clutch engagement are thus increased to their former values.
