Method for controlling the oil level in a gearbox, and gearbox for carrying out said method

The invention relates to a method for controlling the oil level (h3) in a differential gearbox for a vehicle having an oil sump (3) and an oil reservoir (4) that is pneumatically separated from the oil sump (3). The oil reservoir (4) is connected to the oil sump (3) by way of at least one oil channel (34), and the oil sump (3) is connected to a pneumatic pressure source (8) by way of at least onecontrol valve (7) and an air line (5), wherein in at least one position (B) of the of the control valve (7), the pressure source (8) is pneumatically connected to the oil sump (3). In order to improvethe efficiency, at least one first characteristic operating parameter of the vehicle, according to the invention, is detected, and the control valve (7) is operated in dependence of at least said first characteristic operating parameter, wherein the vehicle speed (v) is selected as first characteristic operating parameter. 本发明涉及种用于控制具有油槽(3)和与油槽(3)气动地分离的储油器(4)的车辆的差速齿轮箱中的油位(h3)的方法。储油器(4)通过至少个油通道(34)连接到油槽(3)，并且油槽(3)通过至少个控制阀(
