Transmission with splash lubrication system

A transmission comprising:

• a transmission case at least partially defining a cavity containing unpressurized fluid;
• a clutch housing further defining the cavity;
• a plurality of rotatable components positioned within the cavity and operable to throw the unpressurized fluid against the transmission case and the clutch housing when rotating;
• a shaft positioned within the case and having an axial passage extending from a first end of the shaft to a second end of the shaft, and having radial passages in fluid communication with the axial passage and with the cavity;
• wherein the transmission case at least partially defines a first chamber at the first end of the shaft and the clutch housing at least partially defines a second chamber at the second end of the shaft;
• wherein the transmission case and the clutch housing are configured to collect the thrown fluid and direct the collected fluid to the first chamber and the second chamber, respectively;
• wherein the transmission case is formed with a catcher configured to collect the fluid when the fluid is splashed and a slot configured to direct the collected fluid to the first chamber;
• a plurality of transmission components in fluid communication with the cavity through the axial passage and the radial passages;
• a first cap connected to the transmission case between the first chamber and the first end of the axial shaft;
• wherein the first cap has an opening aligned with the axial passage and an orifice offset from the opening;
• wherein fluid flows through the orifice when fluid reaches a first level in the first chamber and flows through the opening when fluid reaches a second level in the chamber different than the first level;
• wherein the first cap has multiple formations that further define the first chamber and only one of which radially aligns with the slot;
• and
• wherein fluid is provided through the axial passage from both ends of the shaft to the plurality of rotatable components.

A transmission comprising:

• a transmission case at least partially defining a cavity containing unpressurized fluid;
• a rotatable component positioned within the cavity and operable to throw the unpressurized fluid against the transmission case when rotating;
• a shaft positioned within the case and having an axial passage extending from a first end of the shaft to a second end of the shaft;
• wherein the transmission case is formed with a catcher configured to catch at least some of the thrown fluid and a slot configured to direct the caught fluid to a chamber at least partially formed by the transmission case and aligned with the first end of the axial shaft;
• a cap connected to the transmission case and further defining the chamber between the transmission case and the first end of the axial shaft;
• wherein the cap has an opening aligned with the axial passage and an orifice offset from the opening;
• wherein fluid flows from the chamber through the orifice when fluid reaches a first level in the chamber and flows from the chamber through the opening when fluid reaches a second level in the chamber different than the first level;
• a first transmission component in fluid communication with the chamber through the orifice;
• and
• a second transmission component in fluid communication with the chamber through the opening and the axial passage;
• lubrication of the first transmission component relative to the second transmission component thereby determined by fluid flowing from the chamber and by the position and size of the orifice.
