摘要:
An adaptive control system in an automatic four-speed transmission having a unique clutch and gear arrangement which eliminates the need for additional gearing and one over-running clutch, while requiring only one more friction element. The vehicle transmission assembly includes a transmission housing, a rotatable input member, an output member, and a gear assembly for changing the ratio of torque between the input member and the output member. Three clutch assemblies selectively couple the rotatable input member to predetermine gears of the gear assembly and two brake assemblies selectively couple predetermined gears of the gear assembly to the transmission housing. The gear assembly includes the first planetary gear set and a second planetary gear set. The first clutch assembly selectively couples the input member to the second sun gear, the second clutch assembly selectively couples the input member to the first planet carrier, the third clutch assembly selectively couples the input member to the first sun gear, the first brake assembly selectively couples the first sun gear to the transmission housing, and the second brake assembly selectively couples the first planet carrier and the second annulus gear to the transmission housing. An output member is connected to the second planet carrier to allow the output member and the second planet carrier to rotate at the same time.

A method of assembly for a north-south transaxle includes the steps of forming a case with a longitudinal passageway and having an opening generally perpendicular to the passageway. The method also includes forming a head portion and a shaft portion extending from the head portion and installing a front bearing about the transfer shaft and in the passageway. The method further includes installing the transfer shaft in the passageway, installing a rear bearing about the transfer shaft and in the passageway, and retaining the front and rear bearings and transfer shaft in the passageway.

A north-south transaxle includes a case having a first passageway extending longitudinally, a second passageway spaced from the first passageway and being generally parallel to the first passageway and extending longitudinally, and a cavity at one end of the second passageway having an opening generally perpendicular to the second passageway. The transaxle also includes a transmission assembly disposed in the first passageway, a transfer assembly disposed in the second passageway and a structure interconnecting the transmission assembly and transfer assembly for transferring torque from the transmission assembly to the transfer assembly. The transaxle further includes a differential assembly disposed in the cavity and the transaxle is structured to thermally compensate preload on the differential assembly over a temperature operating range.

The present invention is a method of adjusting backlash for a north-south transaxle. The method includes the steps of forming a case having a first passageway extending longitudinally and a second passageway spaced from the first passageway and being generally parallel to the first passageway and extending longitudinally and a cavity at one end of the second passageway having an opening generally perpendicular to the passageway. The method also includes disposing a transmission assembly in the first passageway and a transfer assembly in the second passageway and a differential assembly in the cavity and engaging the transfer assembly. The method further includes preloading the differential assembly, determining the amount of backlash between the differential assembly and transfer assembly, and adjusting the backlash between the differential assembly and transfer assembly.

A push-pull clutch apply piston of a four-speed automatic transmission which utilizes a clutch apply piston with a single pressure plate being pushed by fluid pressure in one direction for applying a clutch assembly and being pulled in an opposite direction for applying an adjacent clutch assembly. The piston has an axially extending flange at an outer periphery thereof, and at least one pressure plate retained to the flange.

Solenoid-actuated valves in a four-speed automatic transmission which are direct-acting and have a non-close clearance design to prevent dirt or other contaminants from interfering with the operation of said valves. The solenoid-actuated valves also include armature having an offset portion extending toward electromagnetic means to be offset toward the center inside the electromagnetic means for efficient magnetic flow.

A valve deactivator is provided that is capable of being activated and deactivated by a pulse energy input. The valve deactivator includes an input member and an output member which are movable relative to one another in the deactivated mode and which are engaged for simultaneous movement in an activated mode. A coil and armature, or other pulse energy input means, are provided to engage and disengage a locking system to activate and deactivate the valve actuator.

An oil level indicator assembly for a vehicle engine including an elongated indicator member removably housed in a tubular sleeve which has spaced upper end and lower end portions with an interior passage therebetween and an internal shoulder-like formation therein. The elongated indicator member has a coil spring formation adapted to engage the shoulder-like formation when the indicator and sleeve are in an assembled relationship, thereby establishing a predetermined length of the indicator to project into the engine oil. The effect of oil on indicia formed on the indicator member when withdrawn from the sleeve member shows the level of oil in the engine.
