摘要:
This invention relates to a preparation comprising a transparent syringe body or container, which has been obtained by molding a resin comprising, as a base material, a propylene polymer, and as a nucleating agent, a phosphoric ester represented by the following general formula (1): ##STR1## and a drug solution charged into the syringe body or container. The preparation is excellent in transparency, free from the dissolution of additives for the resin into the drug solution charged therein even when the drug solution remains charged for a long period of time and hence high in safety. The preparation is useful, in particular, as a syringe preparation charged with a drug solution therein.

A stator of a steering angle sensor is fixed to a steering column through a combination switch case and a stationary bracket, and a rotor of the sensor is rotatably fitted over a steering shaft. A locking collar is slidably but nonrotatably connected to the rotor. The locking collar and the stator are respectively provided with a locking groove and a locking tooth which engage each other to lock the rotor in a predetermined rotational alignment. When the steering angle sensor is not mounted to a vehicle, the locking groove and the locking tooth are brought into engagement with each other by a locking spring to lock the rotor. When a steering wheel is mounted to the steering shaft in a predetermined rotational neutral position of the steering shaft, a clamping pressure caused by the mounting causes the locking collar to be moved to a lockreleasing position or disengage position and the rotor is connected to the steering shaft. In this manner, the rotational neutral position of the rotor in the steering angle sensor can be easily and accurately aligned with the rotational neutral position of the steering shaft so that a signal corresponding to a rotational angle of the steering shaft from the rotational neutral position, i.e., corresponding to a steering angle, can be detected by a pickup of the stator.

A front and rear wheel steering system for a motor vehicle with steerable front and rear road wheels includes a front wheel steering mechanism for steering the front road wheels in response to a steering action effected by a steering wheel of the motor vehicle, a neutral positioning mechanism for normally urging the rear road wheels under a resilient force to a steering neutral position, a rear wheel steering mechanism having an electric motor for steering the rear road wheels out of the steering neutral position, and a controller for controlling an electric current supplied to the electric motor depending on the steering action of the steering wheel. The controller reduces the electric current supplied to the electric motor and subsequently holds the reduced electric current while the motor vehicle is at rest and no steering action is effected by the steering wheel. Preferably, the controller controls the electric current supplied to the electric motor to reach a value which enables the electric motor to produce an output force smaller than the resilient force produced by the neutral positioning mechanism.

A four-wheel steering motor vehicle adapted to prevent a steering ratio of the rear wheels to the front wheels from varying at the time of sudden braking when the pressure of a brake liquid is reduced by an antilock brake unit. This vehicle includes a front wheel steering unit for steering the front wheels in accordance with angular movement of a steering wheel, a rear wheel steering unit for steering the rear wheels, steering control unit for determining a target steering angle of the respective rear wheels based on a vehicle speed and a front wheel steering angle and for controlling the rear wheel steering unit in such a manner that the rear wheel steering unit steers the rear wheel until a rear wheel steering angle reaches the target value, an antilock brake unit for calculating a slip coefficient of each wheel based on a sensed rotating speed of each wheel and for reducing the pressure of a brake liquid being supplied to a brake of the individual wheel when the slip coefficient of the wheel exceeds a predetermined value. The steering control unit controls the rear wheel steering unit so as to substantially prevent the rear wheel steering angle from varying when the pressure to the brake liquid is reduced by the antilock brake unit.
摘要:
The steering operation of a motor vehicle with steerable front and rear road wheels is controlled by steering the rear road wheels with an actuator such as an electric motor which produces a steering force dependent on a deviation of the actual rear wheel steering angle from a target rear wheel steering angle. The rear road wheels are thus controlled with a characteristic dependent on the coefficient of friction of a road on which the motor vehicle travels and the steering speed at which the motor vehicle is steered. Typically, a steering control method comprises the steps of detecting the steering angle of the front road wheels, determining a target steering angle for the rear wheels based on the steering angle of the front road wheels, detecting the actual steering angle of the rear road wheels, calculating a steering angle deviation of the actual rear wheel steering angle from the target steering angle, determining a rear wheel steering force based on the steering angle deviation, and steering the rear road wheels to the target steering angle with the determined rear wheel steering force.

An automobile suspension includes a suspension member coupled to a vehicle body, a disc-shaped actuator mechanism detachably supported on the suspension member, and a knuckle having a swingable support shaft swingably supported for swinging movement about a central pivot through which the axis of the disc-shaped actuator mechanism passes, the knuckle being adapted to support a wheel rotatably. The disc-shaped actuator mechanism includes a pair of actuators disposed thereon at respective positions spaced substantially equally from the central pivot and located on at least one straight line passing through the central pivot, the actuators pivotally supporting the knuckle, respectively, for causing the knuckle to be angularly moved about the central pivot.

A steering system for a vehicle having a steering wheel, steerable front wheels and steerable rear wheels. The system comprises a linkage arrangement operatively interconnecting the steering wheel with the front and rear wheels for steering the front and rear wheels in response to operation of the steering wheel. The linkage arrangement includes a mechanical linkage mechanically connected with the steering wheel so as to transmit steering effort. The mechanical linkage is provided with a restoring mechanism for exerting restoring force to said mechanical linkage so as to urge the steering wheel toward a neutral position thereof. Favorable returnability of the steering system is achieved in this arrangement.
