Abstract

A vehicle transmission has at least one lubrication point, a power take-off, a lubricant tapping point for a power take-off module, and a lubrication system for supplying the lubrication point(s) and the lubricant tapping point with lubricant. The lubrication system includes a lubricant reservoir, a main line section emerging from the lubricant reservoir, a first supply line section leading to the lubrication point(s), a second supply line section leading to the lubricant tapping point, and a return line section leading to the lubricant reservoir. A valve has a first valve port associated with the main line section, a second valve port associated with the lubricant tapping point, a third valve port associated with the return line section, and a bypass duct that acts between the first valve port and the second valve port. A vehicle with such a vehicle transmission and a working machine arrangement are also disclosed.
