    摘要: An automotive vehicle includes a body with an engine compartment. Its power train includes: an engine with a crank shaft and at least one cylinder, mounted within the engine compartment with the crank shaft extending transversely to the longitudinal direction of the vehicle body and with the cylinder extending generally horizontally; a transmission device with a power input shaft, coupled to the engine with the power input shaft substantially coaxial with and rotationally driven from the engine crank shaft; and a differential device, driven from the transmission device, with an axial center line which is located generally below the center line of the crank shaft. Thereby, the engine compartment arrangement can be made compact and low in height, and further the moments of inertia of the vehicle about its yaw and pitch axes can be kept low.

    摘要: A multi-speed transmission having a plurality of forward speed gear trains and at least one reverse speed gear train wherein two parallel shafts, one fixed and the other movable along its axial direction, are mounted within the transmission casing. Shifting forks are mounted on said shafts to selectively engage the forward and reverse speed gear trains. For example, for a multi-speed transmission having five forward speeds and one reverse speed, a first shift fork is slidably mounted on a stationary shaft to selectively engage the first and second gear trains, a second shift fork is slidably mounted on the slidable shaft to selectively engage the third and fourth gear trains and a third shift fork is mounted on the slidable shaft so as to be slidable in only one direction to engage the fifth speed gear train. Movement of the slidable shaft in the direction opposite that which engages the fifth speed gear train acts to engage the reverse speed gear train. The shift forks are retained in their selective position by retaining mechanisms which have retractable protrusions engageable with notches in the shafts.

    摘要: A motor vehicle such as a four-wheel drive vehicle having a first axle shaft which is driven by a drive source and a second axle shaft which is driven by the same drive source, each of a pair of wheels associated with the second axle shaft being powered by way of individual variable torque transmitting devices, further comprising: a steering condition sensor; and a control unit which reduces a torque transmission ratio of one of the variable torque transmitting devices corresponding to the inner one of the wheels of the second axle shaft when the steering condition sensor has detected a steering angle greater than a prescribed value. Thereby, the problem of the tight turn braking can be avoided without losing the advantages of four-wheel drive. Other driving conditions such as braking and acceleration as well as an excessive temperature increase in each of the variable torque transmitting devices may be taken into consideration in carrying out the control of the variable torque transmitting devices which preferably consist of viscous couplings. Each of the viscous couplings is provided with means for externally varying the torque transmission ratio thereof and transmits torque between input and output thereof at a level which is substantially proportional to the speed difference between input and output thereof.
