A hydraulic drive system trailer is provided and generally includes a first rotor assembly arranged along a first side of the frame and having a first rotor and a first drive shaft extending through and connectable with the first rotor, a first motor assembly disposed along the first side of the frame and positioned linearly the first rotor assembly and a second rotor assembly arranged along a second side of the frame that is opposite the first side and having a second rotor and a second drive shaft extending through and connectable with the second rotor.

A friction clutch includes a reference plane aligned perpendicular to a rotational axis, a first clutch component, and a second clutch component. The first clutch component has a first friction element, a first support part that receives the first friction element, a leaf spring unit including a leaf spring that rotationally fixes the second support part to the first support part. The second clutch component has a second friction element. The first friction element lies against the second friction element in a frictionally locking manner in a closed position, and is axially spaced from the second friction element in an open position. The leaf spring is designed and positioned relative to the reference plane in a set angle in the closed position such that an additional axial force is applied to the first friction element and the second friction element in a drive rotational direction of the first clutch component.

Coupling mechanisms for torque transmitting shafts are provided with sliding and fixed plates operably connectable to respective torque transmitting shafts, and a leaf spring having a preloaded spring force exerted on the sliding plate when the sliding and fixed plates are operably connected to one another. A hub is attached to the leaf spring and coaxially received within the sliding plate to allow the sliding plate to be capable of reciprocal axial movements relative to the hub between engaged and disengaged positions wherein the sliding and fixed plates are engaged and disengaged with one another so as to allow and prevent torque being transmitted from one to another of the shafts, respectively. An inner piston is coaxially received within the hub and moveable between a first position wherein the hub retains the sliding plate in the engaged position thereof, and a second position wherein the hub releases the sliding plate to allow movement of the sliding plate under bias force from the leaf spring into the disengaged position thereof.

A drive train unit for a hybrid vehicle includes an input shaft arranged for rotationally fixed attachment to an output of a transmission, an output shaft, an electric machine with a rotor, a clutch, and an actuating unit operatively connected to the clutch. The actuating unit has an actuator and an actuating bearing, displaceable by the actuator. The clutch may be a separating clutch operatively inserted between the rotor and the input shaft, or a friction clutch operatively inserted between the input shaft and the output shaft. The clutch may be a self-intensifying clutch with a leaf spring adjusted at a set angle relative to a reference plane oriented perpendicular to an axis of rotation such that, in a driving direction of a first clutch component, a first friction element is applied to a second friction element with an additional axial force.

The invention relates to an electrically driven clutch actuators (1) for actuating the clutch of a transmission of a vehicle. An actuator comprises a spindle nut (11) on a spindle (9) and a pressure piece (13) displaceable relative to the spindle nut (11) and coupled to the spindle nut by a biasing spring (15). By rotation of the threaded spindle under a driving force of an electric motor (5), the spindle nut (11) compresses the biasing spring (15) and displaces the pressure piece (13) to disengage the clutch. A latching mechanism (16) is configured to limit displacement of the spindle nut away from the pressure piece under the force of the expanding biasing spring when the driving force is reduced below a predetermined level. Further, a control unit is described that reduces the driving force in response to a trigger condition to reduce power consumption in the clutch disengaged state.

When a collision occurs, a driving force of a drive shaft is transmitted to a reversing high-load multiple disk clutch via an inertia absorbing gear mechanism. Then, the driving force is transmitted to a gear via a gear, and inertia is absorbed and the driving force acts to rotate an output shaft at a low speed. On the other hand, when the gear rotates, a regenerative/backing up motor also rotates, and so-called regenerative driving is also performed. Due to these operations, the output shaft rapidly decreases in rotation speed, and goes into a rotation stopping state from a forward rotating state. Then, when a vehicle speed sensor detects that the vehicle speed has reached “0,” the regenerative/backing up motor is driven, the output shaft is driven to rotate reversely for several seconds, and thereafter, driving of the regenerative/backing up motor is stopped.

Transmission systems, disconnect mechanisms, and methods of assembling disconnect mechanisms are envisioned. A disconnect mechanism is adapted to selectively decouple a driving device from a driven device. The disconnect mechanism includes a lever, an inner shaft, an outer shaft, and a housing. The inner shaft is coupled to the lever, the outer shaft is coupled to the inner shaft, and the housing at least partially houses the inner shaft and the outer shaft.

A working vehicle includes a vehicle body, a cabin on the vehicle body, a clutch pedal in the cabin, a clutch on the vehicle body, a clutch operator to engage and disengage the clutch, a linkage including first and second ends, the first end being connected to the clutch operator, and a linkage lock to interlock the clutch pedal with the second end of the linkage so that vibrations of the cabin are reduced or prevented from being transmitted to the clutch.

A clutch assembly includes a clutch hub, a clutch drum disposed about the clutch hub, a first gear connected to the clutch drum, the first gear configured to be coupled with a first shaft, the clutch hub configured to be coupled with a second shaft, a clutch pack disposed between the clutch hub and the clutch drum, and an air-actuated piston assembly for selective actuation of the clutch pack to connect or disconnect two drive axles in a tandem axle assembly. The clutch assembly includes a plurality of lever arms disposed between the piston assembly and the clutch pack. Each lever arm extending to engage the piston and the clutch pack. Each lever arm may be pivotally mounted to a lever carrier plate or to a fixed portion of the piston housing.

A friction clutch includes a housing, an axially displaceable pressure plate, a lever system for displacing the pressure plate, a ramp system arranged between the pressure plate and the lever system, a torsion device for rotating the ramp system, and a control device. The torsion device has a spindle to drive the ramp system and a drive gear with an external profile. The control device has a fastening portion fixed to the housing and a pawl with a plurality of tongues to forming a positive interlock. At least one tongue is arranged to engage the external profile. Each tongue is separated from another tongue by a gap extending in the axial direction. At least one gap, starting from a tip of the tongue, extends in the axial direction 30% or less of a minimum distance between the tip and the fastening portion.
