A hybrid module for a motor vehicle for coupling an internal combustion engine includes a disconnect clutch, an electrical machine, a dual-clutch device, a disconnect clutch actuating system, a first actuating system, and a second actuating system. The disconnect clutch is for transmitting a first torque from the internal combustion engine to the hybrid module and disconnecting the hybrid module from the internal combustion engine. The dual-clutch device includes a first partial clutch and a second partial clutch. The disconnect clutch actuating system is for actuating the disconnect clutch. The first actuating system is for actuating the first partial clutch. The second actuating system is for actuating the second partial clutch. The disconnect clutch actuating system, the first actuating system, and the second actuating system are arranged next to one another in an axial direction.

An electric wheelchair includes a main frame; a driving wheel supported by the main frame; an electric motor disposed on the main frame to drive the driving wheel; a clutch that switches a power transmission path from the electric motor to the driving wheel between an engagement state and a disengagement state; and a clutch operation handle configured to be moved in a predetermined range in an up-down direction. The clutch operation handle is configured so that when the clutch operation handle is stopped at a lowest position of the predetermined range, the clutch is operated so as to be in one of the engagement state and the disengagement state, and when the clutch operation handle is stopped at a highest position of the predetermined range, the clutch is operated so as to be in the other state.

A clutch assembly may have an axially slidable first plate, an axially fixed second plate disposed opposite the first plate, and a clutch pack arranged between the first plate and the second plate. The clutch pack may have a number of axially slidable consecutively arranged friction plates and separator plates. The assembly may also have an actuator axially movable between a first position and a second position, where, in the first position, the clutch pack is opened and, in the second position, the clutch pack is closed and the friction plates are frictionally engaged. The assembly may also have a return spring configured to bias the actuator in a direction away from the clutch pack towards the first position. The assembly may also have an engagement spring element configured to exert an elastic force on the clutch pack.

The present disclosure relates to a transmission of an agricultural vehicle, the transmission including: a forward shift unit for performing shift with respect to drive transmitted from an engine of an agricultural vehicle; a clutch unit connected to the forward shift unit so as to selectively output drive transmitted from the forward shift unit; an adjustment unit connected to the clutch unit; and a backward shift unit connected to the adjustment unit so as to perform shift with respect to drive transmitted from the adjustment unit. The adjustment unit includes: a first adjustment mechanism connected to a first clutch mechanism included in the clutch unit; a second adjustment mechanism connected to a second clutch mechanism included in the clutch unit; and an integration mechanism connected to both the first adjustment mechanism and the second adjustment mechanism. The backward shift unit includes one backward shift mechanism connected to the integration mechanism.

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.

A drive assembly including a primary inertia plate and clutch plate is disclosed herein. The primary inertia plate is configured to be rotationally driven via a crankshaft. The clutch plate includes a body with a rotational axis (X). The clutch plate is configured to be rotationally driven by the primary inertia plate. The clutch plate includes at least one imbalance feature such that a center of gravity of the clutch plate is positioned away from the rotational axis (X). The imbalance feature generates a centrifugal force that counteracts or prevents rattling from being imparted to the clutch plate via engine vibrations through the primary inertia plate.

A prime mover includes a stator provided in a housing, a rotor provided to be rotatable relative to the stator, and a magnet provided in the rotor, and is operated by energization and capable of outputting a torque from the rotor. A magnet cover is provided to cover at least a part of the magnet. The speed reducer includes a sun gear, a planetary gear, a carrier, a first ring gear, and a second ring gear. The carrier is provided on a radially outer side of the sun gear and on a radially inner side of the first ring gear and the second ring gear to come into contact with the magnet cover or the rotation portion.

A rotary actuator includes a housing, a motor, a speed reducer, and a rotational translation unit. The motor includes a stator that includes a coil and is fixed to the housing, and a rotor that is provided with a magnet and rotates when the coil is energized.
