摘要:
A driving torque control apparatus has a first differential restraining device which restrains a rotational speed differential between front-left and front-right wheels by adjusting driving torque to be transmitted from a power source mounted on a four-wheel drive vehicle to each of the front-left and front-right wheels, and a second differential restraining device which restrains a rotational speed differential between rear-left and rear-right wheels by adjusting driving torque to be transmitted from the power source to each of the rear-left and rear-right wheels. An adjustment of driving torque by the second differential restraining device is executed in preference to an adjustment of driving torque by the first differential restraining device.

An optical disk recording thereon compressed moving picture data and an optical disk reproduction apparatus each capable of easily effecting trick play such as high speed reproduction and a retrieval operation at a high speed. Additional information necessary for trick play is recorded in an arbitrary area of an optical disk such as a TOC (Table of Contents) or a leading sector (sector 0) of the disk, and a sector address is added to each sector. To conduct trick play, an I picture, a P picture and a B picture contained in a GOP layer inside a bit stream of compressed image data are extracted and reproduced in accordance with a reproduction speed by looking up a trick play table.

A snow vehicle of the saddle-riding type utilizes essentially the same upper structure as a motorcycle but mounts a ski on the front fork for steering and an engine-driven endless belt track assembly for powering the device. The endless belt track assembly is arranged for mounting on a rear arm structure in order to maintain surface contact between the endless belt and the snow and thereby improve the operating efficiency of the vehicle. The arm may be pivotally mounted or integral with a rear fork pivotally mounted to the vehicle. An improved endless belt construction is described in which the belt is strengthened by core members and the driving cogs of particular configuration and disposed at prescribed locations with respect to the propelling lugs in order to maintain surface contact between the belt edge and the snow surface during cornering. Also disclosed are various forms of cover structures for the track assembly that prevent the scattering of snow from the belt onto the rider or vehicle parts. Grab rails attached to the rear swing arm elements facilitate manipulation of the vehicle in confined spaces. A stopper belt adjustment is also shown mounted to a rear fork with the stopper belt extruding to an articulated rear swing arm structure. The adjustment accommodates for adjustments to the drive chain for tensioning.

A braking apparatus for a motor vehicle equipped with a master cylinder and a wheel cylinder. The apparatus further includes a pump coupled to a reservoir tank to suck a braking liquid from the reservoir tank and pressurize and discharge the sucked braking liquid when a slip of the wheel occurs at the time of driving the wheel, a pressure adjusting valve provided in a pipe coupling a discharge side of the pump to the reservoir tank and arranged to be openable to restrict the discharge pressure of the pump to a predetermined value, and a change-over valve for establishing a communication between the discharge side of the pump and the wheel cylinder when a slip of the wheel occurs at the time of driving the wheel and for establishing a communication between the master cylinder and the wheel cylinder when the slip does not occur. The apparatus controls a braking pressure adjusting device provided between the change-over valve and the wheel cylinder for adjusting the braking pressure to be applied to the wheel cylinder when a drive slip of the wheel occurs, thereby suppressing the drive slip. This arrangement allows the size-reduction of the apparatus and the suppression of generation of operating sound.

The invention relates to an electric motor driven vehicle having a driving unit assembled with a motor and transmission mechanism. In order to avoid a load in a low rotational state of the motor, the transmission mechanism is connected with the motor and driving wheel within a range of predetermined rotational numbers in which the motor approaches the vicinity of maximum efficiency. Accordingly, motor driving is possible from the start, and because of the small electric power and the low heat generating quantity, cruising distance is extended and the apparatus is consequently made to be compact and of light weight. The transmission is provided with an automatic starting clutch and an automatic transmission, and when a belt type stepless speed change transmission is used as the automatic transmission, operation of the motor near the vicinity of maximum efficiency can always be maintained in the usual speed change range. The driving unit can be constructed compactly as a power unit of swing type. Further, an advantageous cooling mechanism of the motor and a wiring structure of an electric power supply cord are disclosed herein.

摘要:
A braking control apparatus for use in a motor vehicle having at least one wheel comprising a master cylinder for generating a hydraulic pressure in response to a braking operation of a vehicle driver, an accumulator for accumulating a hydraulic pressure and at least one wheel braking cylinder for braking the wheel in accordance with a hydraulic pressure supplied thereinto. A passage system is provided so that the wheel braking cylinder is communicated therethrough with the master cylinder and the accumulator. In the passage system are provided first and second change-over valves for cutting off the pressure from the master cylinder, cutting off the pressure from the accumulator and a third control valve disposed between the wheel braking cylinder and the master cylinder or the accumulator for establishing and cutting off the communication therebetween. An control unit controls the operations of the first to third valves so as to, in response to cutting off the communication with the accumulator, establish the communication with the wheel braking cylinder, and then establish the communication with the master cylinder. This valve control prevents the high-pressure remaining in the passage system after the cutting-off of the communication with the accumulator from being rapidly applied to the master cylinder.
