An engine assembly may include an internal combustion engine and an expander couplable to the internal combustion engine in a force transmitting manner. The engine assembly may also include a pulley mounted rotatably on a shaft of the expander. The pulley may be coupled to the internal combustion engine in a force-transmitting manner via a belt drive. The engine assembly may further include a first driver plate connected non-rotatably to the pulley and a second driver plate arranged adjacent thereto and connected non-rotatably to the shaft. The engine assembly may additionally include a clutch device including at least one actuating device and a coupling wheel. The coupling wheel may contact the first driver plate and the second driver plate when the clutch device is closed such that the pulley is connected with the shaft of the expander in a driving manner.

A hydraulic clutch system that enables automatic emergency braking (AEB) and remote start of a manual transmission vehicle. The hydraulic clutch system includes a piston-operated hydraulic cylinder or other accumulator to store a charge of hydraulic fluid that can be selectively routed to the clutch and discharged under electronic control to thereby disengage the clutch independently of any operator input via the clutch pedal. By doing so, the system can provide an improved AEB response that slows or stops the vehicle without stalling the engine. The system may also be used to provide remote start capability to the vehicle by automatically disengaging the clutch as part of a remote start sequence of operations.

A clutch actuator (1) for actuating a vehicle clutch includes a cylinder (3) filled with pressure medium. An annular piston (4) is axially displaceably arranged in the cylinder. The annular piston (4) is fixedly operatively connected to a sliding sleeve (5) slidably mounted on a guide sleeve (6). A radially inner casing surface (16) of the annular piston (4) has an inner radius (Ri) and is arranged radially next to the guide sleeve (6). A slip ring (18; 19) supports the sliding sleeve (5) on the guide sleeve (6). The slip ring (18; 19; 18a) is inserted into a groove (27; 28) in the radially inner casing surface (16). In order to be able to mount undivided slip rings, the groove (27; 28) has a single radially extending groove wall (29; 32) and is open toward an axially outer or inner end face (30; 33) of the annular piston (4).

A hybrid module for a motor vehicle for the coupling of an internal combustion engine includes a separating clutch by means of which the internal combustion engine can be separated from a drivetrain of the motor vehicle and by means of which torque can be imparted to the drivetrain by the internal combustion engine. The hybrid module also has an electric motor which, for torque transmission, is connectable by means of a main clutch to the drivetrain. A separating clutch actuation system is used for effecting an actuation of the separating clutch. A main clutch actuation system is used for effecting an actuation of the main clutch. Both actuation systems are arranged between the separating clutch and the main clutch.

The invention relates to composite pigment particles containing calcium phosphate, their manufacture and their use in coatings, plastics and laminates. The composite pigment particles contain titanium dioxide pigment particles and precipitated calcium phosphate. In one embodiment, the composite pigment particles additionally contain an inorganic and/or organic filler as an extender, preferably selected from the group comprising Ca, CaMg and Mg carbonates, natural and synthetic silicon dioxide and oxides. The composite pigment particles are manufactured in a combined process of dispersion and precipitation. Depending upon the combination selected, use of composite titanium dioxide pigment particles of the invention can provide improved optical properties such as tinting strength or permits pigment savings with little to no loss of optical properties. In particular, the composite pigment particles of the invention can be used to replace part or all of the titanium dioxide contained in the user's system.

A pneumatic clutch actuator includes an actuator housing, a piston assembly, a bearing carrier, and a locking element. The piston assembly is disposed within the actuator housing and is movable between a first position and a second position. The piston assembly has a piston head, an elongate member extending from the piston head, and a lock ring coupled to the elongate member. The bearing carrier supports a bearing and is slidably disposed on a portion of the actuator housing. The locking element is operatively connected to the piston assembly and engages the bearing carrier to adjust a total length of the piston assembly as the piston assembly moves from the second position towards the first position to compensate for wear of the clutch assembly.

A ball bearing includes a fixed inner ring able to bear against an axially movable piston, a rotatable outer ring, and one series of balls between the fixed inner ring and the rotatable outer ring. The rotatable outer ring also includes a folded portion able to bear against a resilient biasing member. The ball bearing can be integrated into a clutch thrust bearing device. The clutch thrust bearing device can be integrated into a driveline system. The driveline system can be included in an all-wheel drive driveline system of a motor vehicle.

A hybrid module for a motor vehicle power train, including an input side for connecting to an internal combustion engine, an output side for connecting to a drive wheel, an electric drive motor comprising a stator and a rotor and a torque transfer device arranged between the roto and the output side. The transfer device is designed to reduce rotational irregularity.

A clutch for a drive train of a motor vehicle includes a bearing, a torque transmission part, a torque output part, and a torque introduction part. The torque output part is connected to the torque transmission part in a non-rotational manner. The torque introduction part is connectable to the torque output part for torque transfer, and supported on the torque transmission part by the bearing.
