Abstract: A differential device includes: an input member; a case member arranged coaxially with the input member; a one-way clutch arranged between the input member and the case member and transmitting torque therebetween only when the input member attempts to rotate in a normal rotation direction; a pinion gear supported by the case member to rotate about the axis perpendicular to the center axis of the case member; and a pair of side gears supported coaxially with the input member to rotate relative to the input member and the case member and meshing with the pinion gear.

Abstract: A cone clutch for a vehicle including a hub, a sleeve, and a clutch ring including a clutch cone, may further include a first friction ring for forming frictional force with the clutch cone, an internal middle cone, a second friction ring, an external middle cone, and a third friction ring, which are sequentially mounted to be brought into contact with each other. When the third friction ring is pressed by the sleeve and the third friction ring, the external middle cone, the second friction ring, the internal middle cone, the first friction ring, and the clutch cone are sequentially brought into close contact with each other, the distances from the hub in an axial direction gradually increase in the order of the first friction ring, the internal middle cone, the second friction ring, the external middle cone, and the third friction ring.

Abstract: In a differential that is part of a selectively disconnectable or connectable secondary powertrain, a clutch device allows the input member of the differential, via which driving power is introduced into the differential, to be uncoupled from the output members to which the driving power is forwarded in a branched manner in order to be able to completely shut off part of the secondary powertrain in the disconnected state.

Abstract: A drive assembly for a motor vehicle has a multi-step transmission and a differential drive. The multi-step transmission comprises a rotatingly drivable driveshaft and an intermediate shaft parallel to the driveshaft, and at least one first transmission stage and a second transmission stage for transmitting torque from the driveshaft to the intermediate shaft with different transmission ratios, as well as a shift unit, wherein the intermediate shaft comprises an output gear for transmitting torque to a differential carrier of the differential drive, wherein a rotational axis of the differential carrier extends parallel to the intermediate shaft, wherein the output gear and the shift unit are arranged axially between the at least two transmission stages, and wherein the driveshaft comprises bores for supplying lubricant.

Abstract: A synchronizing device of a transmission is provided with a cylindrical synchronizer body having an external toothing. A shifting sleeve includes, but is not limited to an internal toothing. The internal toothing axially displaceably meshes with the external tooting of the synchronizer body. A synchronizing ring includes, but is not limited to a locking gear rim. In clearances distributed on the circumference of the synchronizer body, pre-synchronizing elements are arranged. The pre-synchronizing elements are in spring-elastic engagement with the shifting sleeve and are arrested by the shifting sleeve in a middle position. A face end of the locking gear rim includes, but is not limited to outward bulges in direction of the pre-synchronizing elements subject to the setting of spacing between synchronizing ring and pre-synchronizing elements.

Abstract: A gearshift mechanism for a synchronized gear change transmission of a motor vehicle, having a gearshift sleeve which is displaceably supported on a synchronizer body and which can be brought into operative engagement with a gear wheel via at least one synchronizer ring. To support the synchronization process, first and second recesses are formed in the inner peripheral face of the gearshift sleeve, and locking blocks with a spring-loaded ball are provided on the synchronizer body, which engage in the recesses in certain shift positions. For preliminary and subsequent synchronization, the first and second recesses formed in the inner peripheral face of the gearshift sleeve be radially and axially offset and each cooperate with a spring-loaded ball.

Abstract: A constant-mesh transmission having a synchronizing mechanism, the synchronizing mechanism including a fifth gear which acts as a shifter so as to rotate integrally with a counter shift and movably in the axial direction, a recess formed in a first gear, and a synchronizer ring. A first connection spline formed in the outer circumferential wall face of the recess and a first synchronization spline formed in the outer circumferential face of the synchronizer ring have a predetermined overlap portion, whereby they overlap partly in the axial direction. In the fifth gear, a second connection spline meshes with the first connection spline and a second synchronization spline presses the first synchronization spline in the axial direction to make the synchronizer ring and the first gear come into frictional engagement with each other.

Abstract: Spline teeth 66 formed in the inner periphery of a sleeve 45 slidably supported on a hub 63 fixed to a rotation shaft each comprise a projecting portion 66a constituted by a first inclined surface &agr;, a flat surface &ggr; and a second inclined surface &bgr;, and these projecting portions 66a bias a blocking ring via a synchro-spring 71 in an axial direction to thereby generte a synchronizing load between the sleeve 45 and a gear 37. Immediately before the projecting portions 66a of the spline teeth 66 of the sleeve 45 moving rightward mesh with dog teeth 37a of the gear 37, the second inclined surfaces &bgr; of the projecting portions 66a move and ride on the synchro-spring 71 so as to gradually reduce a pressing force axially applied to the blocking ring 67, thereby making it possible to provide a smooth mesh engagement between the spline teeth 66 of the sleeve 45 and the dog teeth 37a of the gear 37.
