Abstract: A gearbox arrangement with an oil circuit, including at least one lubrication point incorporated in the oil circuit and at least one direction control valve with at least two switching positions and at least three ports, the at least three ports including a first port, a second port, and a third port. In a first switching position the first port and the third port are connected to each other in an oil-conducting manner and disconnected from the second port. In a second switching position, the first port and the second port are connected to each other in an oil-conducting manner and disconnected from the third port. The lubrication point and the second port are connected to each other in an oil-conducting manner. The lubrication point and the third port are not connected to each other in an oil-conducting manner.

Abstract: A shaft-bearing subassembly (10) which includes at least one shaft (11) mounted by way of at least first and second roller bearings (13, 14). The first and second roller bearings (13, 14) are mounted on the at least one shaft (11) with an intermediate space between them. The first roller bearing (13) is fixed axially and the second roller bearing (14) is secured by way of a retaining element (16). The retaining element (16) is on the side of the second roller bearing (14) farthest away from the first roller bearing (13), and has a first contact surface (17) which limits the movement of an inner race (18) of the second roller bearing (14) in at least one direction, and a second contact surface (19) which is in contact with an abutment (20) on the shaft (11).
