摘要： A porous insert for a gearbox or transmission which retards fluid motion and flow within the device when it is subjected to rapid acceleration. The insert may be fabricated of any porous material such as open cell plastic foam, a porous ceramic or sintered metal and is shaped to conform to and is installed in a bottom rear region of the transmission housing. The insert retards motion of the fluid during rapid acceleration, preventing pump starvation and permitting a smaller charge of fluid to be placed in the gearbox or transmission.

摘要： A transmission is provided including a sump at least partially defining a sump volume and operable to contain a fluid. The transmission further includes a hydraulic pump. An inlet tube is disposed at least partially within the fluid and is operable to communicate the fluid from the sump volume to the hydraulic pump. A fluid displacement reservoir defining a reservoir volume and disposed at least partially within the sump volume is also provided. The fluid displacement reservoir is operable to selectively displace or impede the movement of at least a portion of the fluid when the fluid within the transmission is subject to acceleration, such that the amount of the fluid required within the sump volume to maintain the inlet tube disposed within the fluid is reduced. The fluid displacement reservoir is also operable to selectively contain or receive at least a portion of the fluid.

摘要： A control system that generates one of a normal mode and a hot mode signal to control operation of a transmission includes a calculator that calculates a predicted temperature of a torque converter and a comparator that compares the predicted temperature to a threshold temperature. A timer generates one of the normal mode and the hot mode signals based on the predicted temperature and the threshold temperature.

摘要： A hydraulic fluid storage apparatus for a transmission has a main sump and a secondary sump. The secondary sump is connected with the main sump through a restricted flow passage. The fluid within the main sump is subjected to centrifugal forces by rotating components within the transmission, such that at high speeds and high levels in the main sump, the restricted passage is closed by a centrifugal dam thereby resulting in fluid storage within the secondary sump. The fluid storage in the secondary sump returning to the main sump when the speed of the rotating components is reduced.
