Abstract: A connecting assembly at a driveshaft between the driveshaft and a wheel hub, having end toothing of an outer joint part of a constant velocity joint of the driveshaft, which outer joint part is at the wheel hub end, and having end toothing of the wheel hub, wherein the end toothings are axially inserted into one another and circumferentially engage one another in a play-free way and wherein the teeth of the end toothings each comprise radially outwardly opening circumferential grooves which are delimited by two flanks and which, jointly, form a circumferentially extending annular groove in which, on the outside, there is arranged a securing ring; as well as a connecting assembly at a driveshaft between the driveshaft and a shaft flange, having end toothing of an outer joint part of a constant velocity joint of the driveshaft, which outer joint part is at the shaft flange end, and having end toothing of the shaft flange, wherein the end toothings are axially inserted into one another and circumferentially eng

Abstract: A transmission joint of the sliding type has a joint body (12) and a tripode (14) having three arms (16) each of which is capable of sliding between two parallel and plane surface portions (36) by means of an articulation element (18) which is carried by the arm (16) of the tripode (14) and which comprises two parallel and opposite plane faces (20) each of which interacts with one of the plane surface portions (36) with interposition of a row of bearing needles (32), wherein the joint body (12) comprises three bearing races each comprising two tracks (38) each of which consists of a component comprising a plane surface portion (36) and a convex cylindrical surface portion (40) which interacts with a complementary concave cylindrical bearing surface (42) formed in the joint body (12) with respect to which it is capable of pivoting, and in that each arm (16) of the tripode comprises a journal on which the intermediate articulation element (18) is mounted to revolve about an axis (Y-Y) parallel to its opposite p

Abstract: A transmission joint body has a plurality of bearing passageways for articulation elements distributed around the axis of the body and, each comprising two raceways arranged to cooperate with articulation elements of the transmission joint. Each raceway includes a first surface of a metal member, a second surface of which is associated with a complementary surface of the joint body and, formed in a portion of the joint body. The body is made of a composite material of a reinforced thermosetting or thermoplastic matrix. The second surface of the metal member is capable of displacement relative to the complementary surface of the joint body.

Abstract: The joint comprises a tulip element (1) connected to a driving shaft and having three axially extending petal portions (8), a tripod element (3) having three radial arms (4) carrying spherical sectors (18) cooperative with inner spherical bearing surfaces (21) of rollers (6) associated with rolling tracks (7) on the tulip element (1). The tripod element is fixed to a bowl element (9) which is connected to a wheel stub-axle (11). Each arm (4) of the tripod element (3) comprises a portion (15) which is off-center in a radial plane relative to a central ball (5). Two flat surfaces (19) are provided between the spherical sectors (18) and an arrangement for axially connecting the tulip element (1) to the tripod element (3) comprises a central spider element (24) having three branches (25) adapted to cap in a radially floating manner the ball (5) of the tripod element.

Abstract: A drive unit and which permits a convenient adaptation to various configurations. This sub-assembly mainly comprises a hollow shaft (6) driven by the output member (4) of the unit, and a differential (7) disposed in the hollow shaft and whose two output elements (11, 12) are connected to two homokinetic joints (14, 21). This device may also include a torsional vibration damping device (5) and a mechanism (23) for controlling the differential.

Abstract: A two-speed planetary change gear mechanism 28 is added to a basic eight-speed change gear mechanism to provide a 16-speed transmission, the planetary transmission 28 including a manually operated forward/reverse gear mechanism. The two-speed mechanism is mounted within the housing 16 of the eight-speed mechanism. The forward/reverse mechanism includes a shift coupler 84 engageable with gears 80, 82 mounted about a shaft 78 which is coaxial with the upper shaft 30 of the eight-speed mechanism. The input gear 86 which is driven by the forward/reverse gears 80, 82 is mounted on the second shaft 38. The two-speed planetary gear set 96 is coupled on its input side to input shaft 98 and on its output side to shaft 78.

Abstract: This specification discloses a transmission clutch brake for use in a torque delivery gear system. A rotatable clutch disc driven by an input shaft and selectively engageable by a pressure plate carries a pair of plates. The plates embrace a brake plate carrying friction material on opposite faces thereof. Upon disengagement of the pressure disc from the clutch plate one of said plates of said pair is moved axially relative to the other thereof in a clamping manner to grip the brake plate against rotation. The latter brake plate is connected to a stationary splined hub utilizing a snap ring. The ring acts as a torsion spring and permits limited slight rotation of the brake plate and clutch disc clamped thereto as well as the input shaft to facilitate meshing of gears of the transmission.
