A constant velocity housing is provided to couple a plunging CV joint with a transaxle. The constant velocity comprises an elongate housing configured to retain the plunging CV joint and a splined shaft configured to engage with a transaxle. A locking system removably retains the splined shaft within the transaxle. The locking system comprises a lock pin in mechanical communication with pins slidably retained within radial holes disposed in the splined shaft underneath a snap-ring. An actuator moves the lock pin to push the pins to operably change a diameter of the snap-ring. When the actuator is loosened, the snap-ring constricts to a diameter less than the diameter of the splined shaft, allowing removal of the splined shaft from the transaxle. When the actuator is fully tightened, the snap-ring assumes a diameter greater than the diameter of the splined shaft, such that the spline shaft remains engaged with the transaxle.

A spline connection having a hub with a toothing profile on the inner circumference, an axle journal having a toothing profile on an outer circumferential portion, a shoulder for axial support and/or abutment against the hub, and a tensioning device for axially bracing the axle journal with the hub. The hub has a constant toothing profile and the axle journal has a first portion and a second portion with different toothing profiles. The first portion is arranged on the insertion side to be further away from the shoulder than the second portion and has a constant toothing profile with play with respect to the toothing profile of the hub. The second portion is arranged on the shoulder side and has a toothing profile which has reduced tooth spaces compared with the first portion and which is play-free with respect to the toothing profile of the hub.

A flap device for a motor vehicle comprises a flap housing that can be flowed through by a gas flow; and a flap shaft that is rotatably supported about an axis of rotation in the flap housing by means of at least a first and a second bearing element, which are held at the flap housing, and that carries a flap for selectively blocking or throttling the gas flow. The flap shaft is supported at the first bearing element in a first axial direction via a fixed abutment element that is axially fixedly arranged with respect to the flap shaft. The flap shaft is supported at the second bearing element in a second axial direction, which is oriented opposite the first axial direction, via a movable abutment element that is axially displaceably seated on the flap shaft, with the movable abutment element being preloaded in a direction toward the second bearing element by means of a spring device, and with the spring device in this respect being supported at a support surface fixed to the shaft and thus pressing the fixed abutment element against the first bearing element.

According to the disclosure a drive shaft connecting unit is provided. This comprises a vehicle-side drive shaft connecting device according to the disclosure and an accessory-side drive shaft connecting device according to the disclosure which can be releasably and interlockingly connected thereto and coupled therewith.

An engine assembly defining an axial direction (A) and including a gearbox, an engine core including at least one rotor, and a flexible coupling shaft having a first end and a second end along the axial direction (A). The first end of the flexible coupling shaft is connected to the engine core and the second end of the flexible coupling shaft is connected to the gearbox. A damper system is positioned at the second end of the flexible coupling shaft. The damper system is configured to reduce vibrations to the flexible coupling shaft during operation of the engine assembly.
