摘要:
A system for mounting a dust shield to a vehicle transmission's clutch/transmission housing by attachment by fasteners along only the accessable lower edge portion and by providing structure which upon assembly pivots an otherwise unsupported corner of the dust shield against a housing surface which inhibits vibration and noise generation.

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 The effect of oil on indicia formed on the indicator member when withdrawn from the sleeve member shows the level of oil in the engine.

This application concerns a leaf type spring for closing valves in a cylinder head of an internal combustion engine. Specifically, the leaf spring has an edge base which is attached to the cylinder head and a cantilevered unsupported portion which extends therefrom. The unsupported portion is bifurcated to form two arms, each arm engaging a valve in a manner biasing it towards its closed operative position and yieldably permitting the valve to be moved toward its open operative position.

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 speedometer drive assembly for use with an automotive transmission includes an adapter housing for securing the assembly to a transmission housing, a rotatable take-off gear received in the adapter housing and engageable with a geared output shaft of the transmission, a cable drive assembly operatively connectable to a speedometer and received in the take-off gear to a position drivingly engaging the take-off gear, and fastener means operative to retain the take-off gear in the adapter housing in a position wherein meshing engagement with the transmission output shaft is effected and to lockingly retain the cable drive assembly in the adapter housing.
摘要:
A pendulum absorber system attenuates torsional vibrations within a drive train of a vehicle. The system can be incorporated between an engine and an automatic transmission, for example, within a flex plate assembly attached to an engine's crankshaft, within a pump housing cover of a torque converter, or as a stand-alone unit between a flex plate assembly and a torque converter. The system includes at least one pendulum weight that dynamically moves along a predetermined path in response to variations in rotational velocities of a housing of the system and that is tuned to attenuate excitation of torsional vibrations within the drive train. A limiter assembly, which can include multiple limiters, is provided within the system for stopping movement of the weight when it reaches endpoints of the predetermined path, by mechanically impeding further movement at both of a first and second end of the weight.
摘要:
An overrunning clutch assembly for an automatic transmission including a transmission housing, an input member, an output member, a plurality of gearsets for changing a ratio of torque between the input member and the output member, and at least one brake assembly to selectively couple predetermined gears of the gear assembly to the transmission housing, the overrunning clutch assembly including an inner race operatively connected to the brake assembly, an outer race operatively connected to the transmission housing, and a structure disposed between the inner race and outer race for allowing the brake assembly to rotate in only one direction.
摘要:
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.

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.
