摘要： PURPOSE: To reduce the squeak of a brake by installing a cup-shaped piston for giving the displacement to a brake pad and installing a weight through an elastic body in the inside space. CONSTITUTION: A disc brake is equipped with a cup-shaped piston 4 for giving a displacement to an inner pad 1 by the high pressure generated in a brake booster and a caliper 5 which is equipped with the piston 4 built in and supports the nipping operation of a disc rotor 3, and a weight 7 is installed through an elastic body 6 in the inside space of the piston 4. When the mass of the weight 7 is (m) and the spring constant of the elastic body 6 is (k), the characteristics vibration frequency of the weight 7 f0 =(1/(2π))√(k/m) is set lower than the squeal frequency fS due to a brake shoe. Accordingly, the squeak of the brake in brake application can be reduced, and the effect is large on a large-sized vehicle having the large size of the disc brake, and even if the brake pad is replaced, the change of performance is not generated, and the reduction of generation of squeak can be continued.

摘要： PURPOSE:To back up a braking fall of the front two-axle side in a front two- axle and rear one-axle car. CONSTITUTION:Double check valves 12a and 13a are arranged at a junction of two-system backup oil pressure lines 12b and 13b which are branched off from rear axle braking oil pressure lines 12 and 13 and are joined respectively to respective oil pressure lines 11f and 11r to brake front two axles and front and rear axles. When the oil pressure lines 11f and 11r to be joined on the more upstream side than the junction are fallen, a checking object is switched to the upstream side of the fluid lines 11f and 11r to be joined from the side of the backup fluid lines 12b and 13b, so that a decrease in braking capacity caused by a fall of the front two-axle side can be backed up by the braking oil pressure lines 12 and 13 on the rear axle side.

摘要： PURPOSE:To use light and cheap material for a flange part to enable light weight by dividing a disc brake rotor into a flange part and a disc part, manufacturing respective parts out of suitable material for respective purposes, and thereafter connecting both parts. CONSTITUTION:A disc part 1 having an axially projected connecting part 9 on the center part is formed by casting or forging. A flange part 2 has a derby hat-like projection for forming a projected part 8 connecting with the connecting part 9 of the disc part 1 on the center part of one side, a connecting part with a wheel hub on the other side, and is formed by press working of plate material. Nextly, the blockading part on the extreme end of the derby hat-like projection is cut off to form the projected connecting part 8, the connecting part 9 of the disc part 1 and the projected connecting part 8 are mutually butt-jointed, and the desired disc brake rotor is obtained.

摘要： PURPOSE:To aim at making a brake force booster compact, in a vehicle incorporating two systems of front and rear wheel pneumatic-hydraulic converters, by coupling the penumatic parts and the hydraulic parts in two systems with each other in series each system on one drive shaft. CONSTITUTION:A brake force booster 8 has air pressure chambers (e), (f) into which air from front and rear brake valves which are manipulated by a brake pedal is introduced through passages (a), (b), respectively, and a piston rod PR is moved rightward by means of diaphragms DF1, DF2 in accordance with pressures in the chambers (e), (f). Due to the movement of the piston rod PR, hydraulic pistons OP1, OP2 arranged in series and coaxially with the piston rod PR are slid in the same direction. At this time, ports P1, P2 are closed to pressurize oil in chambers r1, r2 and to feed the oil into front and rear brake lines through ports (c), (d).

摘要： PURPOSE:To avoid locking of front and rear brakes by switching two front relay valves selectively in accordance to the pavement conditions having different frictional factor thereby controlling the brake force of front and rear brakes. CONSTITUTION:The service brake 10 suitable for large bus is constituted with two systems of front brake 11 and rear brake 12. The front and rear hydraulic brakes 13, 14 are coupled respectively to relay valve-less front air booster 15 and relay valved rear air booster 16. The air brake piping 26 for coupling said booster 15 to an air pressure source 24 is coupled in parallel with first front relay valve 17 having the brake cylinder pressure gradient corresponding with the rear relay valve 39 of rear booster 16 and second front relay valve 18 having lower pressure gradient than said one thus to function each valve 17, 18 selectively through a changeover valve 20.

摘要： PURPOSE: To reduce the discomfortable noise of the brake squeak generated in the brake application on a vehicle, in an effective form. CONSTITUTION: Each rod 6 is installed on the inner surface of a rim 3 on which a brake lining 2 is installed, and/or on the side surface of a web 3a, and at the top end of a web, and a weight 5 is installed through an elastic body 4 on the rod. When the mass of the weight is (m) and the spring constant of the elastic body is (k), the characteristic vibration frequency of the weight installed through the elastic body f0 =(1/2π)√(k/m) is set nearly equal to the squeak frequency fS due to a brake shoe or lower than the squeak frequency fS. Accordingly, the brake squeak of a large-sized vehicle having the large size of the brake shoe can be reduced to the sufficient degree in the actual use only by adding the inexpensive parts, and the essential performance can be maintained even if the replacement of the brake lining is carried out.
