SOLUTION: A ridge riding-over arm 63 is provided at a front part of a traveling car body freely to be turned and formed freely to be switched between the front projecting condition that the arm is turned downward and the rear housing condition that the arm is turned u...

In driving force controlling apparatus and method for a four-wheel drive vehicle, a command is outputted to a front-and-rear wheel driving force distribution control system to reduce a clutch engagement force of a clutch, such as a frictional clutch, when a subtraction value of a detected value of a clutch transmission torque from that of a clutch input torque (Tinp - Tr) is smaller than a predete...

PROBLEM TO BE SOLVED: To make driving force fit for a road condition and improve traveling performance and drivability by detecting a traveling state of a preceding vehicle preceding a four wheel drive car and controlling a torque distribution rate by a torque distribution rate control means in accordance with the traveling state. SOLUTION: In the case when there is control information of driving ...

PROBLEM TO BE SOLVED: To switch the driving force to the weak condition when stopping a vehicle while restricting the instantaneous backward movement when a brake pedal is operated. SOLUTION: Even in the condition that the operation of an acceleration pedal is released at the predetermined car speed or less, the driving force is transmitted from a motor to driving wheels in the case where a travel...

PROBLEM TO BE SOLVED: To provide a control valve support plate where the center of a spring member is positioned on the central axis of a cylinder space. SOLUTION: A projection 25 vertically rising cylindrically is installed in the center of a control valve support plate 24. An internal thread structure for clamping an external thread member 26 is formed upon piercing through the center of this pr...

PROBLEM TO BE SOLVED: To surely prevent a nose dive phenomenon just before stopping. SOLUTION: A judgment is made that a preceding vehicle stops from an inter-vehicle distance between one's own vehicle and the preceding vehicle detected by an inter-vehicle distance sensor 1 and a time change in one's own vehicle speed detected by a wheel speed sensor 2 (YES of S1). A reference speed at which creep...

A scanning electron beam CT system generates an electron beam along a beam source axis offset from the scanner axis, or axis of symmetry, thereby permitting the X-ray subject to pass completely through the stationary gantry. The electron beam is produced with the first drift tube region of an evacuated housing chamber, and is directed downstream toward a second region that includes a gantry. A sca...
