An adaptive control device is provided for a vehicle starting clutch. The adaptive control device includes a reverse brake as the starting clutch, and a clutch adaptive controller. The reverse brake is interposed between an engine and motor/generator, and the left and right rear wheels and is slip-engaged at a time of starting. The clutch adaptive controller performs clutch adaptive control, in which the reverse brake is subjected to a state in which a temperature of the reverse brake is at, or above, a second threshold for a timed period, at least one time before a vehicle begins to move.

A fixing mechanism for a lifting device is provided. The lifting device includes a motor and a transmission shaft driven by the motor. The fixing mechanism includes a support body, a fixing assembly, a bearing, and a connection assembly. The fixing assembly includes a base plate fixed above the support body and a chamber disposed between the base plate and the support body. A bearing is arranged in the chamber and clamped between the support body and the base plate, and the transmission shaft passes through the bearing and protrudes from the base plate. The connection assembly is sleeved on the transmission shaft to together connect with the motor. Accordingly, power transmission efficiency may be improved, and vibration and noise generated during operation of the motor may be reduced.

A drive assembly for a motor vehicle clutch is provided. The drive assembly includes a damper including a plurality of springs, a first cover plate and second cover plate. The first and second cover plates support the springs therebetween and the second cover plate includes an outer portion extending radially outside of the first cover plate. The drive assembly further includes a subassembly including at least one clutch facing and at least one support segment supporting the at least one clutch facing. The at least one support segment includes an outer radial portion fixed to the at least one clutch facing and an inner radial portion connected to the outer portion of the second cover plate to connect the subassembly to the damper.

The present invention provides an engine connection structure for a hybrid transmission. The engine connection structure includes: a connecting mechanism having an edge connected with a mass by a connecting plate and connected to a counter-rotor shaft; and a drive plate being opposite to the connecting mechanism, positioned at a crankshaft, and connecting the mass and the crankshaft to each other.

A damper device includes a first rotor, a second rotor, an elastic coupling part elastically coupling the first and second rotors in a rotational direction, and a hysteresis generating mechanism. The hysteresis generating mechanism generates a hysteresis torque and includes a friction member. The friction member is configured to make frictional contact with the first or second rotor. The friction member does not make frictional contact with the first and second rotors in a first torsion angular range where torsion is caused from a neutral condition to a first side and a second side in the rotational direction. The friction member makes frictional contact with the first or second rotor so as to generate a hysteresis torque in a second torsion angular range exceeding the first torsion angular range. The friction member is set in a neutral position by actuation of the elastic coupling part in the neutral condition.

The hysteresis generating mechanism includes a friction member, and generates a hysteresis torque. The friction member does not make frictional contact with the first and second rotors in a first torsion angular range where the torsion is caused between the first and second rotors by a first torsion angle from a neutral condition, makes frictional contact with the first or second rotor in a second torsion angular range exceeding the first torsion angle so as to generate the hysteresis torque, and does not make frictional contact with the first and second rotors in a predetermined torsion angular range within the second torsion angular range. In the neutral condition, the friction member is set in a neutral position by actuation of the elastic coupling part.

An isolating decoupler comprising a shaft having an outer surface, a pulley rotationally engaged about the shaft, a torsion spring having a first section having a major diameter and a second section having a minor diameter, the major diameter is greater than the minor diameter, the torsion spring engaged with the pulley, a wrap spring having an inner diameter less than an outer surface outer diameter, the wrap spring frictionally engaging the outer surface, the torsion spring having an end fixedly connected to the wrap spring, the torsion spring loaded in a winding direction whereby the diameter of each coil of the torsion spring decreases in a progressive sequence as a load increases, the second section is disposed radially outboard of the wrap spring such that the second section moves radially inward to clamp the wrap spring during a load condition, and the pulley comprising a member disposed to progressively release the wrap spring from the shaft outer surface upon occurrence of a predetermined load condition.

An electromagnetic brake (10) including a plurality of elastic members (25) which are arranged between an engagement surface of a brake pad (13) and an engagement surface of a hub (12) symmetrically about a center of rotation of the shaft (11). The biasing directions of the plurality of elastic members are in a rotational direction of the shaft.

A clutch disc includes an input part, an output part, and a vibration damper. The vibration damper includes a first part with a first flange area, a second part with a second flange area, a spring device, and first and second intermediate parts. The intermediate parts are coupled to the first flange area and the second flange area by respective slide devices such that movement of the intermediate parts relative one another is inhibited by the spring device. The flange areas are each in operative connection with the input part and the output part such that a load acting on the input part that changes from either rotational direction to an opposite rotational direction moves the first flange area relative to the second flange area in a single fixed direction of movement.
