CPC F16H 57/0435 (2013.01) [B60K 17/28 (2013.01); F16H 57/0424 (2013.01); F16H 57/0436 (2013.01); F16H 57/045 (2013.01)] | 9 Claims |
1. A vehicle transmission with 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 at least one lubrication point and the lubricant tapping point with lubricant, the lubrication system comprising:
a lubricant reservoir
a main line section emerging from the lubricant reservoir;
a first supply line section leading to the at least one lubrication point;
a second supply line section leading to the lubricant tapping point;
a return line section leading to the lubricant reservoir;
a valve with 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 extends between the first valve port and the second valve port, and
the valve is configured to be switched, based on a pressure applied at the first valve port, between a first shift position in which, regardless of a bypass flow, a lubricant flow between the first valve port and the second valve port is blocked and a lubricant flow between the first valve port and the third valve port is also blocked, a second shift position in which, regardless of the bypass flow, the lubricant flow between the first valve port and the second valve port is enabled and the lubricant flow between the first valve port and the third valve port is blocked, and a third shift position in which, regardless of the bypass flow, the lubricant flow between the first valve port and the second valve port is enabled and the lubricant flow between the first valve port and the third valve port is also enabled.
