摘要:
An automatic transmission including a first number of dry clutches; a second number of brakes; a third number of actuators; and transfer elements. The transfer elements are connected to respective clutches and brakes by respective uninterruptible mechanical paths. The actuators are arranged to displace respective transfer elements to operate the dry clutches and brakes. The third number is less than a sum of the first and second numbers. The transmission can include an input to a drive unit; a gear set; a damper connecting the drive unit and gear set; and an uninterrupted torque path between the drive unit and gear set. The transmission can include: a fluid chamber; dry portions; a six speed gear set at least partly in the chamber; three shafts at least partially disposed in the chamber; and three sealing elements forming a fluid-tight seal among the shafts, chamber, and dry portions.

A hydrokinetic torque converter for use with a transmission in the power train of a motor vehicle has a housing rotatable by the engine and containing a pump, a turbine and at least one stator as well as a rotary output device connected to the input shaft of the transmission. The pump is normally rotatable by the housing; the turbine is rotatable (a) by the fluid which is circulated by the pump or (b) by the housing in response to engagement of a lockup clutch; and the stator can be connected to the stationary case of the transmission or is rotatable by the circulating fluid. First and second hubs are non-rotatably but axially movably mounted on the output member and are respectively connectable with the turbine and the stator by suitable clutches. The hubs can move axially relative to the output device between several positions in one of which the turbine can drive the input element of the transmission in a forward direction, in another of which the stator can rotate the input element in a direction to drive the vehicle rearwardly, and in a third of which the transmission is in neutral gear.

A drive system, including a torque converter with a housing arranged for connection to a combustion engine for a vehicle; and an air-operated motor, connected to the housing, for providing torque to the housing for the torque converter; or an air compressor, connected to the housing, for using torque from the housing to compress air. In one embodiment, the system includes a compressed air accumulator for providing compressed air to the air-operated motor; and a heat exchanger for transferring heat energy to compressed air provided to the air-operated motor from the accumulator. A drive system, including a combustion engine with a crankshaft; a plurality of pistons and cylinders for combusting fuel; and a cylinder and piston, the piston connected to the crankshaft. The system also includes a compressed gas accumulator for supplying compressed gas to the cylinder to operate the first piston to provide torque to the crankshaft.

A friction clutch having a tiltable clutch spring can be disengaged by tilting the spring with a bearing which can be moved axially to engage the tips of radially inwardly extending prongs of the spring. The bearing is movable axially by an actuator which, in turn, is movable axially and away from a support by a system of ramps and rolling elements. The ramps or the rolling elements are caused to move radially of the axis of the bearing in order to move the rolling elements or the ramps axially in a direction to cause a tilting of the spring and hence a disengagement of the clutch.

A clutch plate for use in friction clutches of automotive vehicles has three units which are angularly movable with reference to one another, and two sets of coil springs. The first unit has two rigidly connected spaced-apart disc members one of which carries the friction linings and can be driven by the flywheel of the engine. The second unit has a hub which can drive the input shaft of a change-speed transmission and a flange consisting of three radially outwardly extending arms which are rigid with the hub and disposed in pockets defined by two mirror symmetrical intermediate discs constituting the third unit. The intermediate discs are disposed between the disc members of the first unit and have peripheral notches for distancing elements which connect the disc members to one another and can perform limited angular movements in their notches. The intermediate discs extend radially beyond the arms of the flange and have projections which extend, with angular play, between the arms of the flange. One set of coil springs is installed in registering openings of the arms and intermediate discs to oppose relative angular movement between the second and third units, and the other set of springs is installed in registering windows of the disc members and intermediate discs to oppose angular movements of the first and third units with reference to one another. Friction generating devices are interposed between the first and second, first and third and/or second and third units.

The present invention broadly comprises a power transmitting assembly for a vehicle, including a transmission power output for a manual transmission in the vehicle and a torque-filling element. The torque-filling element is arranged for connection to an engine in the vehicle, is connected to the transmission power output and is arranged to modify engine torque from the engine and to provide the modified engine torque to the transmission power output during a shift to a gear in the manual transmission. The torque-filling element includes a hydrodynamic torque-transmitting device, a rotation adjustment element to modify rotational speed associated with the engine, and a coupling element to interface the engine torque with torque on the transmission power output. In some aspects, the rotation adjustment element is arranged for connection to the engine. In some aspects, the coupling element is arranged for connection to the engine.
