摘要： In an anti-skid control system for a motor vehicle, brake fluid pressure reduction-control mode and brake fluid pressure buildup-control mode occurs cyclically; in the reduction-control mode, reduction of the brake fluid pressure is started on the basis of detection of an abrupt drop in wheel speed which occurs when the wheel is braked; and in buildup-control mode, a valve is repetitively opened and closed so that brake fluid pressure buildup and holding operations are performed alternatley and repetitively, whereby the brake fluid pressure is caused to build up gradually. The length of time period for the first buildup operation in the buildup-control mode is determined on the basis of variation in the wheel speed occurring between a low peak point and a high peak point; and the length of time period for at least one of each pressure holding operation and each of the second and succeeding pressure buildup operations in the abovementioned buildup-control mode, is determined on the basis of variation in the wheel speed occurring immediately before the pressure holding or buildup operation is started.

摘要： In a device for preventing a wheel lock condition of a vehicle, a fluid passage switching valve is inserted in a rear wheel brake fluid pressure transmission system. The fluid pressure switching valve is closed during brake application in so far as it is within a braking force range in which a rear wheel braking force must be lower than a front wheel braking force. The speeds of revolution or deceleration of the front and rear wheels are compared by comparison means. When the comparison means detects that the deceleration of the front wheel becomes greater than the deceleration state of the rear wheel by a predetermined value, the fluid passage switching valve opens for a given length of time to allow the rear wheel brake fluid pressure to increase.

摘要： An improvement of a hydraulic pressure control device for a double piping type hydraulic system for vehicle brakes not only performs braking pressure control over both of two independent hydraulic pressure channels but also is capable of transmitting the same degree of hydraulic pressure to the rear wheels of a vehicle as the front wheels thereof by releasing one hydraulic pressure channel from a control action when the other hydraulic pressure channel becomes defective, so that insufficiency in the braking force on the whole vehicle resulting from such a defect can be effectively compensated.

摘要： A disc brake is provided with a fluid pressure operating mechanism for a service brake and concurrently with a mechanical operating mechanism for a parking brake. A parking lever of the parking brake is connected to an adjusting bolt through a spindle and a connecting link and further connected to a piston slidable in a cylinder through a sleeve nut. The adjusting bolt is prevented from rotation by a stopper plate fixed to the cylinder. The adjusting bolt and the sleeve nut are connected by thread and provided therebetween with a stopping means of rotation which allows a forward rotation of the sleeve nut toward a disc but limits a retracting rotation of the sleeve nut from the disc. The stopping means of rotation is provided with a locking means which effectively prevents a retraction of the sleeve nut. A clearance between friction pads and the disc is automatically adjusted by the fluid pressure operating mechanism when linings of the friction pads are worn more than a predetermined amount. Thus, the parking brake is ensured of a predetermined lever stroke at all times.

摘要： A cam housing assembly oscillates in association with rotation of an eccentric cam which is attached to a camshaft and is allowed to press a clutch by cam pins of the cam housing assembly. A pair of piston assemblies are provided of which each includes a piston which can slide within a sleeve, a spindle and a nut which screws on to the spindle and are supported in hole portions in a caliper body so as to oscillate therein, whereby a brake pad is pressed against by a plug after the spindle, the nut and the piston are sequentially pressed by pressing a clutch by the cam pins. Since the spindle and the nut are screwed on to each other through a reversible screw, a gap is adjusted automatically as the pad wears.

摘要： A joining link, a strut, and first and second expansion levers constitute an expansion and contraction device. At the time of the braking, the proximal end portion of both of the expansion levers are mutually pressed from the opposite sides by first and second pressing members constituting a driving device. The reaction due to the braking is offset by the joining link portion, whereby a large force is not applied to the back plate or the like.
