PURPOSE:To avoid the need of increasing the dimension of a speed change selecting device for increasing the torque corresponding to the deceleration ratio by arranging the speed change selecting device for a four wheel drive device in front of a planetary gear device. CONSTITUTION:A speed change selecting device 36 is arranged between a supporting part for an input shaft 31 and output shaft 34 and...

PURPOSE:To shorten the axial length of a driving device by arranging a differential device between a planetary gear device for speed change and a transmission device and constituting a common part between the planetary gear device for speed change and the transmission device. CONSTITUTION:A double pinion type differential gear device 40 is arranged on the rear wheel side of a planetary gear set 35...

PURPOSE:To prevent the generation of an unreasonable strain force in a vehicle dive system by slowly lowering the engine speed at time of sharp accelerator deceleration operation, in the start control in which an electric type automatic clutch is operated in interlocking with the engine speed. CONSTITUTION:An acceleration signal A is input into an aimed speed calculation part 31, and the aimed spe...

A device for the rapid detection of hydrocarbon fire inside an armored vehicle. Infrared radiation resulting from the appearance of the fire is detected using lithium tantalate as a pyroelectric sensor for producing a voltage signal. A voltage pulse is produced at the beginning of the infrared radiation. Alternatively, the current signal of the pyroelectric sensor may be used and subsequently inte...

A driverless guided vehicle movable along a guide path includes a wheel support device for supporting a wheel disposed in rolling engagement with a floor. The wheel support device is resiliently mounted on a body of the guided vehicle for vertical movement relative thereto. A detecting means for detecting the guide path and sensible markings along the guide path is fixedly secured to the wheel sup...
