摘要:
A wheel angular acceleration sensor for a vehicle anti-lock control device wherein the tendency of the wheel going toward a locked state resulting from an excessively great braking force of the brake applied thereto is detected by overrun rotation of the flywheel and the overrun rotation is converted into an axial displacement of the flywheel by the cam mechanism to output it as a signal for controlling the braking force, the sensor having an aligning mechanism interposed between an output shaft rotated in association with the wheel and the cam mechanism as well as a friction clutch plate for allowing the overrun rotation of the flywheel, whereby when a deflected load is exerted on the cam mechanism or the friction clutch plate due to an error in machining or the like at the time of occurrence of a thrust at the cam mechanism, the aligning mechanism works to overcome the deflected load, allowing the flywheel to displace smoothly and accurately in the axial direction.
摘要:
An anti-lock brake system employing an anti-lock control unit between a brake master cylinder and a front wheel brake. The brake system is applied to a damped telescopic front fork and includes an anti-dive device which operates to increase damping force upon application of braking force to the front brake. In a first embodiment, the anti-dive device operates from hydraulic pressure upstream of the anti-lock brake unit. In a second embodiment, reaction force to braking of the wheel is sensed and employed to actuate the anti-dive device.
摘要:
A braking system employing an antilock device which has two brake actuating mechanisms responsive to input hydraulic pressure through the antilock device. Valves are provided in the control mechanism for a second brake actuating mechanism which provide hydraulic cylinders for controlling the brake mechanism. The hydraulic cylinder of such a valve is vented until the controlling hydraulic system reaches a minimum pressure level. This pressure level is determined to be above that of the residual pressure level of the antilock mechanism. In a first embodiment, direct hydraulic control is provided to the multiple brake actuating mechanisms. In the second preferred embodiment, the reaction force to braking of the first brake actuating mechanism controls the brake pressure through a second master cylinder to the second brake actuating mechanism.
摘要:
An antilock brake device for vehicles having a sensor which senses a possibility of locking of a wheel, during braking of the wheel, by an overruning of a flywheel which generates a release signal. A hydraulic pump having a cam shaft rotated in association with the wheel generates hydraulic pressure for antilock control. A gear unit as a transmission for transmitting rotation of the wheel at an increased speed to the flywheel comprises an input member located within and connected to a hub of the wheel, a ring gear formed on the input member, a planetary gear meshed with the ring gear and a sun gear meshed with the planetary gear. The planetary gear is secured to a cam shaft supported on a stationary casing. The flywheel of the sensor disposed within the hub is connected to the gear unit through a drive shaft. The sensor is supported on an axle extending through the hub. The casing encasing therein the antilock controller is disposed at an open mouth of a hub recess, and the input member is provided so as to encircle the sensor. A transmission torque limiter is provided between the wheel and the sensor. The input member is connected to the hub by bolts extending through a hub wall from the side thereof opposite the side where the recess is positioned. One side wall of the casing is supported on one axial end of a cylinder shaft fitted on the axle, and the input member is rotatably supported on the other axial end of the cylindrical shaft. A coupling which assumes a connecting state when the shaft is fitted on the axle is provided between the input member and the wheel.
