An automobile or other wheeled vehicle includes various hydraulic components, including a hydraulic gearbox, transmission, clutch, and brake energy recovery system. Such hydraulic components supplement or replace traditional mechanical components of the automobile or other wheeled vehicle to improve the overall operational efficiency thereof.

A dry double clutch for an electric axle includes a clutch unit and an actuation unit. The clutch unit has a first clutch device for connecting a drive shaft with a first output shaft, and a second clutch device, coaxial to the first clutch device, for connecting the drive shaft with a second output shaft. The actuation unit has a first actuation device for actuating the first clutch device, and a second actuation device for actuating the second clutch device. The first clutch device is closed when the first actuation device is not actuated, and the second clutch device is open when the second actuation device is not actuated. The first clutch device is arranged to be opened by a first pressure force from the first actuation device, and the second clutch device is arranged to be closed by a second pressure force from the second actuation device.

A clutch release bearing (17), in particular for a motor vehicle, having: a tubular body (30) through which at least one input shaft (11) of a gearbox is intended to pass; at least one actuator having a part, movable in translation along the axis (X) of the body (30), intended for actuation of a clutch diaphragm; a target (28a, 28b) whose position is representative of the position of the movable part of the actuator; and a detector (29a, 29b) capable of detecting the position of the target (28a, 28b). The target (28a, 28b) is offset angularly from the detector (29a, 29b) with respect to the axis (X) of the body (30).

The invention relates to a clutch mechanism intended to be installed between an engine and a transmission of a motor vehicle, the mechanism being configured to be installed on a transmission (400) in two steps and by means of a system for axial locking of the control system (300) with respect to the clutch (100, 200). The axial locking system comprises a first axial locking element (304, 302) for implementing at least an axial retention between the control system (300) and the transmission (400), and a second axial locking element (600) for implementing at least an axial retention between the clutch (100, 200) and a shaft (A1, A2) of the transmission, and a means for rotational coupling of the clutch support (500) with respect to the control system (300), the rotational coupling means being different from the axial locking system.

A dry-plate clutch (single or dual) of inverted construction for a vehicle transmission includes a clutch structure with a connecting device arranged to be connected to a prime mover; a pressure plate rotationally fixed and axially displaceable relative to the clutch structure, and a driven disc connected to a driven shaft and located between the clutch structure and the pressure plate. An actuator is arranged to displace the pressure plate between an engaged state, where the driven disc is clamped between the clutch structure and the pressure plate, and a disengaged state, where the disc is rotatable relative to the clutch structure. The connecting device has hollow sections at a number of angular locations extending into a radial surface facing the pressure plate. The pressure plate has corresponding axially extending protrusions in a radial surface facing the connecting device; and the protrusions at least partially extend axially into the hollow sections in the disengaged state.

An automobile or other wheeled vehicle includes various hydraulic components, including a hydraulic gearbox, transmission, clutch, and brake energy recovery system. Such hydraulic components supplement or replace traditional mechanical components of the automobile or other wheeled vehicle to improve the overall operational efficiency thereof.

A disconnect clutch for a drive train of a motor vehicle includes a torque transfer component with a contact region, an outer disc carrier, an application element, and a return spring. The outer disc carrier is rotationally and axially fixed on the torque transfer component, and arranged for receiving rotationally fixed and axially displaceable friction discs arranged for torque transmission with counter friction discs. The application element is for axially displacing at least one of the friction discs for a frictional connection and the return spring is for releasing the frictional connection. The return spring contacts the application element, the return spring comprises a radially outer portion that bears against the contact region, and the contact region is designed to modify a preload of the return spring.

A hybrid module has an intermediate element via which a counter plate, or at least one of the counter plates, of a coupling device is fixedly connected to a rotor element. At least one pressure plate and/or intermediate plate of the coupling device is here connected rotationally fixedly but axially displaceably to the rotor element via the at least one intermediate element. The result is a compact plate connection which is advantageous in particular for multiplate clutches. The intermediate element may be arranged radially outside the plates (pressure plate(s), counter plate(s) and any intermediate plates) of the coupling device.

A hybrid module includes a housing, an electric motor, a hydraulic coupling, a first clutch, a second clutch, and a flow plate assembly. The housing is arranged for fixing to a planetary transmission and an engine. The electric motor is disposed in the housing. The electric motor has a stator fixed to the housing and a rotor rotatable relative to the housing. The hydraulic coupling is disposed in the housing and is at least partially radially inside of the electric motor. The first clutch is for drivingly connecting the rotor to the engine. The second clutch is arranged in parallel with the hydraulic coupling for drivingly connecting the rotor to an input shaft of the planetary transmission. The flow plate assembly is fixed to the housing. The flow plate assembly has a first flow plate with a first radial groove forming a first portion of a first radial flow channel, and a second flow plate, fixed to the first flow plate, forming a second portion of the first radial flow channel.
