  • Patent number: 9003926
    Abstract: An oil passage structure of a chain-driven oil pump includes three lines of oil passages for supplying oil from the center support to the torque converter, a first oil passage for supplying oil to the torque converter through the inside of an input shaft of the torque converter, a second oil passage for supplying oil to the torque converter through a space defined by the outer periphery surface of the input shaft and the inner periphery surface of a stator shaft, and a third oil passage for supplying oil to the torque converter by bypassing the drive sprocket. The third oil passage is provided on the outer periphery side of the drive sprocket and in a position where it does not interfere with the operation of a chain. Accordingly, it is possible to utilize the flex lock-up to a maximum extent, and to reduce the diameter of the sprocket.

  • Patent number: 8956133
    Abstract: An oil pump includes a first spill passage formed on a side surface (60) of a pump chamber (58) to communicate a hydraulic pressure chamber (54) with a first high pressure discharge passage (68) when the entire hydraulic pressure chamber (54) is positioned between the first high pressure discharge passage (68) and a first low pressure discharge passage (70). Therefore, when the hydraulic pressure chamber (54) passes between the first high pressure discharge passage (68) and the first low pressure discharge passage (70), the hydraulic pressure inside the predetermined hydraulic pressure chamber (54) escapes to the first high pressure discharge passage (68) through a first spill passage (76), so a hydraulic pressure value inside the hydraulic pressure chamber (54) is maintained at the pressure value inside the first high pressure discharge passage (68).

  • Patent number: 8943818
    Abstract: A hydraulic device includes a switch-over valve 1140 provided at a section of a sub-passage 1105 located downstream of a location where a first bypass passage 1117 is connected and located upstream of a primary regulator 1110. The switch-over valve 1140 is switched between a blocked state, where supply of hydraulic oil to a section of the sub-passage 1105 located downstream of the switch-over valve 1140 is blocked, and a communication state, where supply of hydraulic oil to the section of the sub-passage 1105 located downstream of the switch-over valve 1140 is permitted. In the hydraulic device, when the switch-over valve 1140 is switched to the communication state, as a discharge performance of a main pump 1102 increases, a first check valve 1118 closes. Supply paths for hydraulic oil discharged from the sub-pump 1103 are automatically switched in accordance with the discharge performance of the main pump 1102.

  • Patent number: 8801559
    Abstract: A vehicular power transmitting system including an oil pump constructed to sufficiently reduce a required drive torque. A high-pressure-port discharge amount of first and second high-pressure passages of the oil pump is determined such that an amount of consumption of working oil of relatively high pressure can be afforded only by the high-pressure-port discharge amount, during steady-state running of a vehicle in which engine speed is not lower than a predetermined threshold value corresponding to a predetermined lowest target input shaft speed of a continuously variable transmission for its shifting control. The pressure of the working oil discharged from first and second low-pressure discharge passages is kept at a predetermined low level, and the required drive torque of the oil pump is sufficiently reduced.

  • Patent number: 8517871
    Abstract: In a vehicular belt-driven continuously variable transmission, belt squeezing force is inhibited from becoming excessive and a safety factor, with respect to belt slip, of belt squeezing force applied to a transmission belt (48) is reduced to a value that is less than or equal to 1.5 by reducing a pressure receiving area (SOUT) of an output side hydraulic cylinder (46c). As a result, a centrifugal hydraulic pressure canceller chamber on a secondary pulley side (46) can be eliminated thus simplifying the structure of the vehicular belt-driven continuously variable transmission, while belt squeezing force can be appropriately controlled.

  • Patent number: 8393999
    Abstract: In a hydraulic control system for a transmission, line pressure Pl is adjusted in accordance with a second solenoid pressure Psls if the ratio of a first sheave pressure Pin with respect to a second solenoid pressure Psls is equal to or less than the gain ?. If not so, the line pressure Pl is adjusted in accordance with the first sheave pressure Pin. Consequently, the gain ? of the first sheave pressure Pin with respect to a first solenoid pressure Pslp at a first sheave pressure adjustment valve 16 and the gain ? of a second sheave pressure Pout with respect to the second solenoid pressure Psls at a second sheave pressure adjustment valve 17 can be individually set while the line pressure Pl can be suppressed to the substantially requisite minimum in the entire control region.
