Abstract: The left rear wheel is driven with the left motor and the right rear wheel is driven with the right motor. Selection of a control mode is made from a first control mode in which the left and right motors are driven in common and a second control mode in which the left and right motors are driven discretely and separately. A region in which the motors are driven is so arranged as to be altered in accordance with the running state of the vehicle, such as the lateral acceleration acting upon the vehicle body, the road surface friction coefficient .mu., the vehicle speed, the steered angle of the steering wheel, etc. A clutch can be disposed to couple the left and right wheels to be driven with the motors when a predetermined condition is met.

Abstract: This invention has as its object to provide a vehicle power train structure, which can decrease the total height and the total length of the entire power train as a combination of an engine, a transmission, a drive shaft, and the like.

Abstract: An open top automobile body including a rigid roof panel extending between the front windshield section and a hoop member of a substantially inverted U-shape mounted at the opposite leg portions to the rear fenders for fore-and-aft swinging movements between an erected position and a retracted position. A foldable hood is provided between the hoop member and the rear body section to provide a rear windshield section. The roof panel is connected at the rear edge through a hinge mechanism with the hoop member so that the roof panel can be retracted into the rear body section together with the hoop member. A locking member prevents a relative rotation of two links of the hinge mechanism with respect to each other when the hoop member is in the erected position and the roof panel is placed between the front windshield and the hoop member.

Abstract: An open top automobile body having a hoop member which is mounted for swinging movement between an erected position and a retracted position.

The rear hood is secured to the rear body section at a position below the upper edge of the rear body section. A peripheral hood tensioning link is provided to force the hood against the upper edge of the rear body section substantially over an entire outer periphery of the hood link.

Abstract: A vehicle rear suspension mechanism capable of producing a toe-in displacement under a side force, a brake force, an engine brake force and an engine drive force to obtain a stabilized steering property. The mechanism includes a suspension member connected with a vehicle body, a wheel hub supporting a rear wheel for rotation about a rotating axis, a connecting device for connecting the wheel hub with the suspension member. The connecting device includes a ball joint connecting the wheel hub to the suspension member pivotably about the joint center. The ball joint is located in one of four quadrants defined in a rectangular coordinate system having its origin on the rotatable axis of the rear wheel. The device also includes a first resilient bushing located between the wheel hub and the suspension member in one of the three remaining unoccupied quadrants and a second resilient bushing located between the wheel hub and the suspension member in one of the two remaining unoccupied quadrants.

Abstract: A vehicle suspension mechanism including a carrier for carrying a rear wheel rotatably about an axis of rotation, a strut assembly having an upper end connected with a vehicle body and a lower end connected with the carrier, a swingable arm pivotably connected through resilient rubber bushes with the vehicle body at a longitudinally spaced first forward point and a first rearward point and with the carrier at a longitudinally spaced second forward point and a second rearward point. The aforementioned points are arranged so that the distance between the line connecting the first forward and first rearward points and the line connecting the second forward and second rearward points increases toward the rearward direction, whereby a toe-in movement is produced when the arm is upwardly swung.

Abstract: A body side support member such as the semi trailing arm of a semi trailing type rear-suspension, the strut of a strut type rear-suspension or the like is connected to a wheel hub for a rear wheel by way of a resilient connecting means such as a pair of resilient bushings to permit the wheel hub to change its position with respect to the body side support member. An end of a stabilizer is connected to the wheel hub so that, when the rear wheel on the wheel hub bumps, the rear wheel is caused to toe in by the counterforce of the stabilizer produced upon bump thereof.
