A hybrid module includes a hybrid module housing which forms a housing interior divided by a partition. The housing interior includes at least one chamber designed as a dry space which is separated from a wet region by the partition, wherein the hybrid module has an electric machine and a first clutch device, in particular a separating clutch, in the dry space and has a second clutch device, in particular a dual clutch apparatus, in the wet region. An output side of the first clutch device is mechanically coupled to the input side of the second clutch device by an intermediate shaft, wherein the intermediate shaft is supported at least radially on the partition via at least one bearing unit.

A clutch cover for a friction clutch and a friction clutch, where the clutch cover forms a ring wall and the ring wall forms a plurality of circumferentially spaced radially extending plates having each a radially outer end. The ring wall also form two or more concentric annular stiffening bands extending at a radial distance from one another and including an innermost annular stiffening band. The ring wall also forms an outermost annular stiffening band, wherein the annular stiffening bands connect the radial plates to each other and having each a radial thickness that is smaller than the radial distance therebetween measured in intermediate regions of the ring wall between respectively two successive radial plates. A plurality of circumferentially spaced drive members of the friction clutch protrude axially from or can be screw connected to said radially outer ends of the radial plates.

Device for coupling two shafts end-to-end, comprising a pair of dog clutch members (16, 28).

Each dog clutch member is configured so as to be able to be secured to an end of a shaft to be coupled, and the two dog clutch members (16, 28) have complementary shapes.

A first dog clutch member (16) is pivotably mounted in a first casing (6).

A second dog clutch member (28) is pivotably mounted in an intermediate bearing (8).

The intermediate bearing (8) is slidably mounted in a second casing (10) assumed to be fixed, the intermediate bearing (8) being able to slide relative to the second casing (10) in a direction parallel to the two shafts to be coupled, termed the longitudinal direction.

The intermediate bearing (8) is elastically prestressed in the direction of the first casing (6).

A cardan shaft for a tool connected to a motor and provided with a system for checking conditions of use thereof. The cardan shaft has a rotatable shaft, with one or two end cardan joints. One or more sensor members are mounted on the cardan shaft to transmit signals to a data acquisition and data-processing electronic control unit (ECU) mounted on a fixed protection of the cardan shaft. The sensor members measure data such as torque transmitted by the cardan shaft, rotation speed of the rotatable shaft, vibrations of the cardan shaft, temperature of the cardan joint and articulation angle. A system for checking conditions of use of the cardan shaft has a remote node connected to the ECU and mounted on the fixed protection. The remote node acquires, stores and processes data sent to the ECU by the sensor members.

A greasing device that feeds grease to a portion requiring greasing that is housed inside a housing, and includes a jig and a greasing pipe fixed to the jig. The housing includes a though-hole that extends through the housing. The jig includes an insertion part that is inserted into the through-hole of the housing. A side surface of the insertion part bear a marking-off line at a position a predetermined distance away from a leading end side of the insertion part. A positon of the marking-off line is a height position that the greasing pipe does not come into contact with inner components of the housing when the jig is inserted into the through-hole up to the positon of the marking-off line.

A gear motor includes a gear mechanism driven via a clutch by an electric motor. The clutch is at least partially enclosed by a protective part, and the protective part includes two cowl parts. The cowl parts are connected to one another and each cowl part includes grill openings, e.g., on their side facing toward the electric motor.

The fluid coupling of the present disclosure transmits torque by a fluid in a variable speed transmission. The fluid coupling comprises a front cover and a back cover, and the front cover and the back cover forming a chamber. The fluid coupling includes a plurality of impeller vanes are located on the back cover and the back cover is configured to rotate in a first direction. The fluid coupling also includes a turbine having a plurality of turbine vanes located within the chamber. The ends of each of the plurality of impeller vanes are curved in the first direction to direct flow of the fluid into the plurality of turbine vanes at a sharper angle thereby increasing torque applied to the turbine.

A portable power tool has a drive unit for rotationally driving a tool receptacle about an axis of rotation, the drive unit having at least one drive motor and a shiftable transmission, which is arranged in a transmission housing with an at least partially sleeve-like clutch housing and a transmission cover fastened thereto. The tool includes a shifting element for shifting the shiftable transmission between at least two different gears, and a locking sleeve for locking the shifting element in at least a first and a second shifting position is arranged in the clutch housing. The shiftable transmission forms, at least in the first shifting position, a cross-sectional plane perpendicular to the axis of rotation in which the locking sleeve is arranged at least regionally between the transmission cover and the shifting element and the shifting element is arranged at least regionally between the locking sleeve and the clutch housing.

A method for assembling a clutch control unit in a transmission clutch housing of a vehicle, the method comprising the steps of coupling the clutch control unit to the transmission clutch housing by a first guide means comprising a first pin and a first slot; coupling the clutch control unit to the transmission clutch housing by a second guide means comprising a second pin and a second slot; and displacing the clutch control unit from a first position at least partially outside the transmission clutch housing to an operative second position within the transmission clutch housing.

A power unit includes: a crankcase which accommodates a crankshaft and a main shaft arranged in parallel to each other; a crank side cover which covers one end portion of the crankshaft from the outside in an axial direction of the crankshaft; a primary driven gear which is provided in the main shaft and meshes with a primary drive gear of the crankshaft; a clutch provided at one end portion of the main shaft; and a clutch cover which covers the clutch from the outside in an axial direction of the main shaft and is fastened and fixed to a packing surface provided on the crankcase to surround the clutch, wherein the primary driven gear and the packing surface overlap in a virtual straight line when viewed from the axial direction of the main shaft.
