  • Patent number: 4986380
    Abstract: A motorized power steering apparatus for a vehicle has a torque sensor including a right turn potentiometer and a left turn potentiometer which generate output voltages corresponding to the steering torque during a right turn or a left turn, respectively. A motor controller controls the output torque of a drive motor which generates an auxiliary steering force corresponding to the output voltage of one of the potentiometers. A logic circuit prevents current from being supplied to the motor when both of the potentiometers generate an output voltage at the same time.

  • Patent number: 4986560
    Abstract: An anti-jackknifing coupling device, for an articulated veicle such as a tractor-trailer combination, comprising a base member for mounting upon the tractor. A turntable member is rotatably mounted upon the base member, and a trailer support member is supported upon, and rotatable with, the turntable. The trailer support member, usually called a "fifth wheel", serves to releasably couple the trailer. A piston-and-cylinder device is connected at its one end to the turntable and at its other end to the base member, so taht it extends substantially diametrically across the turntable member when the vehicle is straight. As the tractor and trailer pivot, the trailer support member and turntable rotate together relative to the base member, causin contraction of the piston-and-cylinder device. The trailer support member will usually be able to tilt relative to the turntable about a lateral pivot axis.

  • Patent number: 4984646
    Abstract: A steering system for a motor vehicle having power steering means including an actuator for turning steerable road wheels of the motor vehicle includes a control mechanism for eliminating a deviation between a desired direction of travel of the motor vehicle and an actual direction of travel of the motor vehicle, based on an output signal from a direction indicating mechanism which indicates the desired direction and an output signal from a direction detecting mechanism which detects the actual direction. The control mechanism determines a target turning angle for the steerable road wheels dependent on the deviation between the desired direction and the actual direction, and controls the power steering mechanism to turn the steerable road wheels up to the target turning angle.

  • Patent number: 4982976
    Abstract: A steering system for use in a towing vehicle-steering trailer assembly, wherein all trailer axles are load-bearing and fixed. The steerable trailer includes a sectored radian steering mechanism which comprises a sectored rack-and-pinion mechanism keyed to the towing vehicle fifth wheel plate. The sectored rack-and-pinion mechanism provides a steering output signal proportional to the relative angle between the towing vehicle and the steerable trailer which approaches an asymptote and thus allows the towing vehicle to turn in relation to the steered trailer without generating the steering mechanism output signal.

  • Patent number: 4982807
    Abstract: A Drive-slip control device for motor vehicles in which, when a driven vehicle wheel spins, this wheel is braked and wherein when both driven wheels spin, the engine power is additionally reduced. Spinning of the drive wheels is recognized by means of rotational-speed sensors and an electronic system and when a spin signal is present on account of a differential-speed threshold value between driven and non-driven vehicle axles being exceeded, the power of the engine is reduced in a controlled manner by the electronic system during the duration of the spin signal by means of a final control element. When the spin signal stops, the power of the engine is increased again in a controlled manner to the target value predetermined by the driver by means of the accelerator.

  • Patent number: 4976452
    Abstract: The present invention solves the problems of the electrical surge and reduced reliability related to the shock loading experienced by previous two wheeled vehicle stands when the stand member contacts the ground during the time it is being driven by the stand motor to a position for supporting the two wheeled vehicle. This is achieved by having a drive mechanism consisting of a plurality of reduction gears to transmit the drive from the stand motor to the stand member, thereby reducing the torque loading on the stand motor, and by mounting the drive mechanism so that it can move relative to the body of the two wheeled vehicle when the stand member first contacts the ground, and restricting this movement with a buffer device which absorbs the shock loading.

  • Patent number: 4972917
    Abstract: A carriage conveying apparatus has a loaded carriage to be conveyed, and a driving vehicle for coupling, towing and conveying the carriage from below the carriage. Since the vertical load of the carriage is transmitted to the driving vehicle, controlled to a proper magnitude, the driving vehicle may be reduced in size and weight, and it is also possible to have stable travel if the carriage is empty. By designing all three wheels so as to be driven and steered, sideways and spin-turn motions are realized. By providing recognition marks and detecting means, it is possible to position the driving vehicle accurately if the setting position of the carriage deviates.

  • Patent number: 4967866
    Abstract: In a traction control system for motor vehicles, the design is made such that during traction control operation, detection is made as to whether both the left-hand and the right-hand driving wheel speed have become equal to or higher than a predetermined threshold value, and detection is also made as to whether one of the driving wheel speeds which is increasing and the other one of the driving wheel speeds which is decreasing, have crossed each other; when the results of such detections are both "YES", this is regarded as an indication that a hunting phenomenon is likely to occur, and in response thereto, buildup and reduction of the brake hydraulic pressure is restricted; during the restriction, detection is made as to whether both of the driving wheel speeds have become equal to or lower than the predetermined threshold value, the above-mentioned restriction is removed.

  • Patent number: 4966380
    Abstract: The hub (3) of the bicycle (1) is connected to a chain-driven sprocket (10, 12) through a sleeve (11) carrying the sprocket(s), and through a driving mechanism which comprises a driving member (15) slidable inside the sleeve (11) and driven in rotation by this sleeve, and a driven member (16) slidable on the fixed axle (8) of the hub. The driving member (15) and the driven member (16) which is linked to the hub (3) through a free-wheel device (19, 24, 25) both carry cams (27) producing an axial thrust which pushes these members (15, 16) apart when they are rotated. This axial thrust is applied through a thrust bearing (33-36) to a sensing device comprising a strain gauge (29) mounted on a flexible non-rotating disk (28) carried on the fixed axle (8). Signals from the sensor are processed by a measuring and display device (6) attached to the handlebar, so that the rider may know at all times the value of the torque transmitted to the wheel.

  • Patent number: 4962824
    Abstract: In a traction control system for motor vehicles, a plurality of threshold values which are higher than the vehicle speed (equal to the non-driving wheel speed) are set up; the wheel speed as increasing or decreasing is compared with the above-mentioned plurality of threshold values to effect buildup or reduction of the brake fluid pressure; and holding of the brake fluid pressure is effected on the basis of a variation in the acceleration/deceleration of the driving wheel; in the case where the holding control mode in which the brake fluid pressure is held, persists for a predetermined time period or longer when the driving wheel speed is higher than a specific one of the above-mentioned plurality of threshold values, the holding control mode is switched to buildup control mode.

  • Patent number: 4958698
    Abstract: The invention pertains to a process for steering a motor vehicle with a conventional steerable front axle and a steerable rear axle, in which the vehicle speed (V) and the front wheel steering angle (LWV) are detected in order to turn the rear wheels as a function of the vehicle speed (V) and the front wheel steering angle (LWV), with a limit angle (LWVgr) for the front wheel steering angle (LWV), being determined depending on the particular speed at which the vehicle is actually traveling (Vist). When a steering maneuver occurs, the actual front wheel steering angle (LWVist) is then continuously compared to the limit angle (LVWgr), and the rear wheels are turned in the same direction when the actual front wheel steering angle (LWVsit) is greater than or equal to the limit angle (LWVgr).
