Dual-clutch transmission

A transmission for a vehicle, comprising:

• an input shaft configured to be operatively connected to an internal combustion engine of the vehicle;
• a gear shaft selectively operatively connected to the input shaft;
• a plurality of transmission gears mounted to the gear shaft;
• a clutch selectively actuatable to transmit motion between the input shaft and the gear shaft for selectively operating the transmission in one of the plurality of transmission gears;
• an output shaft operatively connected to the gear shaft at least in part by the plurality of transmission gears, the output shaft being configured to be operatively connected to at least one ground-engaging member of the vehicle;
• a transmission housing at least partly enclosing the input shaft, the plurality of transmission gears, the clutch and the output shaft, the transmission housing comprising an internal dividing wall defining first and second chambers of the transmission housing, the internal dividing wall being configured to limit flow of transmission fluid between the first and second chambers,
• the input shaft and the clutch being disposed within the first chamber, and
• the plurality of transmission gears and the output shaft being disposed within the second chamber;
• and
• a transmission fluid distribution system configured to distribute transmission fluid within the transmission and fluidly connecting the first chamber to the second chamber, the transmission fluid distribution system comprising:
• a fluid tank defined at least in part by the transmission housing;
• and
• a primary pump fluidly connected to the fluid tank and to the first and second chambers, the primary pump being configured to pump transmission fluid to the first and second chambers,
• the internal dividing wall having a first side defining the first chamber and a second side defining the second chamber,
• the internal dividing wall defining at least one fluid channel extending from the first side to the second side of the internal dividing wall, the at least one fluid channel being fluidly connected to the primary pump to route transmission fluid in a controlled manner from the first chamber to the second chamber, and
• the internal dividing wall defining at least one air hole disposed in an upper portion of the internal dividing wall for balancing a pressure within the first chamber with a pressure within the second chamber.
