The invention relates to a connection arrangement in which two parts can be coupled to a corresponding engagement means without play. A connection device having at least one elastically resilient portion is located in the engagement region of the two engagement means, the elastically resilient portion being stressed based on the coupling of the two parts due to deformation such that the two parts are in mutual engagement without play. Furthermore, a latch element is formed at the elastically resilient portion or at another resilient portion in the engagement region of the two engagement means. The latch element serves as a transport lock and as an installation aid and latches the second part in a predetermined relative position with respect to a third part before the coupling of the two parts.

Connection arrangement

A transmission has a lubricant pump which is arranged in the interior of a transmission housing and which includes a rotor rotationally fixedly connected to a transmission shaft in a pump housing, with the pump housing being rotationally fixedly connected to the transmission housing and being sealed with respect to a cylindrical sealing surface of the transmission housing, and with the lubricant pump pumping into a pressure chamber which surrounds the transmission shaft and which is sealed with respect to the transmission shaft. To achieve a good seal and centration of the pump housing, the pump housing is sealed by means of a resilient ring with respect to the cylindrical sealing surface of the transmission housing, with the ring being received by an outer peripheral groove of the pump housing with radial clearance so that the pump housing can adjust itself in the radial direction.

Transmission having a coaxial lubricant pump

The invention relates to a gearbox comprising a shift fork () that is displaced by an actuator using a shaft (), whereby a rotational displacement of said shaft is translated into a displacement of the shift fork. To achieve an accurate displacement with minimum installation space, the gate () is configured on a sleeve () that is connected to the shift fork unit () in a rotationally fixed manner, said sleeve acting on the shift fork unit () in the direction of the displacement by means of a spring () and the shaft () runs through the sleeve (), said shaft comprising a finger () that protrudes radially and co-operates with the gate. The shift fork unit () forms a housing () that surrounds the sleeve () and the spring accumulator () and that comprises bearing surfaces (), by means of which the shift fork unit () is guided on the shaft () in the direction of the displacement.
