摘要:
An electronic means senses the difference in rotational speed between a main shaft gear to be engaged and the main shaft, and actuates a friction disc assembly to connect the low gear to the main shaft to accelerate the countershaft and thus the gear to be engaged if the gear speed is lower than the main shaft speed, and to connect the first gear to the transmission casing to decelerate the countershaft and thus the gear if the gear speed is higher than the main shaft speed, shifting from neutral into the desired gear ratio is prevented until the gear and main shaft speeds are synchronized.

A suede-like or deer skin-like raised woven or knitted fabric having at least one raised surface is produced by providing a woven or knitted fabric using a yarn consisting of synthetic hollow composite fibers each composed of two or more fiber-forming polyester constituents and two or more fiber-forming polyamide constituents and having a hollow space surrounded by the polyamide and polyester constituents which are arranged alternately with each other and adhered to each other side-by-side so as to form a tube-shaped body, and raising a surface of the fabric while allowing the hollow composite fibers located in at least the raised surface portion of the fabric to be divided into numerous very fine fibrils consisting of said polyester and polyamide constituents.

A limited-slip differential gear unit has end adjustable slip-limitation according to the operation mode of the adjustable suspension system. A control system for the limited-slip differential gear unit, which controls the slip-limitation is associated with a suspension control system to receive therefrom a suspension mode indicative signal to select one of a plurality of preset characteristics to derive a slip-limit control signal. The limited-slip differential gear unit includes a slip-limit adjusting mechanism which is responsive to the control signal for adjusting the slip-limitation to be generated by the limited-slip differential gear unit.

A waste kinetic energy reclaiming system for an engine-driven vehicle includes a generator, and a variable torque-ratio coupling connecting the generator and the vehicle engine. The system also includes a clutch which selectably disconnects the coupling from the engine in response to whether or not braking of the vehicle is required so that the connection between the coupling and the engine is established only when braking is required.

Transfer unit includes a shift rod which is slidably supported at both ends in a transfer case and is adapted to cooperate with a shift fork to effect changeover between two wheel and four wheel drive conditions. The shift fork is supported by the shift rod so as to be movable in both shift directions and is resiliently retained in position on the shift rod.

The present invention relates to a method of producing a twisted polyester filament yarn having a high level of twist used for a woven or knitted crepe fabric.A method of this invention comprises imparting a high level of twist to a polyester filament yarn which has particular properties, and heat setting said twisted polyester filament yarn. The first of these properties which the polyester filament yarn has is that a boil-off shrinkage in boiling water is in the range of 0% to 5%. The second is that a thermal shrinkage stress at 140.degree. C. in hot air is more than 0.03 g/de. The third is that a ratio of a thermal shrinkage stress at 180.degree. C. in hot air to a thermal shrinkage stress at 140.degree. C. is more than 1.0.The polyester filament yarn which has above mentioned properties can be obtained by repeating heat treatment several times at a temperature from 160.degree. C. to 220.degree. C. in hot air, stretching the polyester filament yarn in a range of 2% to 10% and successively shrinking it in the same range, or by being subjected to heat treatment at a temperature from 160.degree. C. to 220.degree. C. in hot air, shrinking restrictively the polyester filament yarn in a range of 0% to 10% under the relaxed state.

A suede-like raised woven fabric which comprises: warp yarns; weft yarns, each being a single twist filament yarn or a loopy textured filament yarn consisting of a bundle of fine fibers; and an elastic polymer applied to the fabric. The bundle of fine fibers consists of a raised portion having an average monofilament denier of from 0.05 to 0.4 and an unraised portion having an average monofilament denier of above 0.4 but not exceeding 0.8. The raised woven fabric is prepared by weaving a fabric using as weft yarn a single twist filament yarn or a loopy textured filament yarn comprising hollow composite fibers, each composed of at least four alternately arranged components of fiber-forming polyester and fiber-forming polyamide which are mutually adhered side-by-side encompassing a hollow space and extend along the longitudinal axis of the fiber to form a tubular body, and dividing the hollow composite fibers into fine fibers to form a bundle of fine fibers consisting of raised and unraised portions by a raising operation. The raised woven fabric has a high density and excellent uniformity of the raised fine fibers, and has excellent suppleness, surface abrasion and pilling resistances.

A travel condition detecting section detects travel conditions of an electric motor car. According to the detected travel conditions, a required output calculating section calculates a required travel output. According to the calculated required travel output, a control commanding section determines travel outputs to be allocated to a plurality of motors coupled to driven wheels of the electric motor car, respectively in such a way that the total power consumption of the motors can be minimized, and further outputs control commands to the motors on the basis of the determined travel outputs allocated to the respective motors.

A four wheel drive system of a vehicle has a transfer clutch capable of varying clutch torque transmitted therethrough from an engine to front wheels. The clutch torque is controlled by a driving force distribution control unit in accordance with a front and rear wheel speed difference determined from signals from front and rear wheel speed sensors. Preferably, the control unit controls a distribution ratio of a front wheel driving force to a rear wheel driving force by controlling the clutch torque of the transfer clutch in such a manner that the distribution ratio decreases as the wheel speed difference increases when the wheel speed difference is positive, that is the front wheel speed is higher than the rear wheel speed, and that the distribution ratio increases as the absolute value of the wheel speed difference increases when the wheel speed difference is negative.
摘要:
A four wheel drive system of a vehicle has a transfer clutch capable of varying torque transmitted therethrough from an engine to front wheels. This torque is controlled by a driving force distribution control unit in response to sensor signals of vehicle cornering behavior sensor such as a lateral acceleration sensor, vehicle speed sensor, transmission gear position sensor, and accelerator position sensor. The control unit determines a driving force distribution ratio between the front wheel driving force and the rear wheel driving force in accordance with the sensed lateral acceleration in such a manner that the share of the driving force apportioned to the front wheels is decreased with increase of the lateral acceleration. The control unit estimates a total driving force produced by the engine and transmitted through the transmission to the transfer, from the vehicle speed, gear position and accelerator position, and determines the torque of the transfer clutch from the total driving force and the distribution ratio.
