Abstract
In an longitudinal type automatic transmission having an input shaft having driving gears, an output shaft having driven gears that are engaged with the driving gears to constitute transmission gear trains, and changeover mechanisms for selecting into a transmission gear train for transmitting a power, the automatic transmission is constructed to have the input shaft, the output shaft, and a driving shaft coupled to a final reduction gear, and has a bypass clutch that is arranged over the final reduction gear to transmit a torque to the output shaft while executing the control in a shifting operation and a start clutch for coupling or decoupling an engine and the input shaft. An oil pump for driving the start clutch and the bypass clutch is arranged over the final reduction gear and near the bypass clutch.
Claims4
An automatic transmission comprising:
- an input shaft to which a plurality of driving gears are provided;
- an output shaft to which a plurality of driven gears are provided, the plurality of driven gears being engaged with the driving gears to constitute a plurality of transmission gear trains respectively;
- a changeover mechanism for selecting the desired transmission gear train which transmits a power, out of the plurality of transmission gear trains;
- a start clutch for setting an engine and the input shaft into an engage state and a disengage state;
- a driving shaft coupled to the output shaft in parallel with the output shaft, the driving shaft being coupled to a final reduction gear;
- and
- a bypass clutch arranged over the final reduction gear and transmitting a torque of the input shaft to the output shaft while controlling connection and disconnection in synchronism with a selecting operation of the transmission gear trains in a shifting operation,
- wherein the manual transmission is arranged longitudinally in an engine room in which the input shaft and the output shaft are arranged in a traveling direction of a vehicle.
