摘要： PROBLEM TO BE SOLVED: To improve the assemblability of the components incorporated in the deep part of a cylinder space 9a arranged in a caliper 5a among components of adjustment mechanism 12a and the parking mechanism, and to realize the structure in which it is less likely to damage the inner circumferential surface of this cylinder space 9a in the assembly work. SOLUTION: Some of the components of a parking brake mechanism are incorporated between an inner side case 45 and an outer side case 46, the two case 45 and 46 are combined by engaging lock holes 51, 51 and lock claws 55, 55, and an inner side auxiliary assembly 59 is formed. In this state, the diameter of circumscribed circle of the lock claws 55, 55 is configured to be smaller. Then, when the inner side auxiliary assembly 59 is incorporated in the cylindrical space 9a, the two lock claws 55, 55 are engaged with a lock concave 61 which is formed on the inner peripheral surface of the cylindrical space 9a by making the two lock claws 55, 55 protrude greatly from the outer peripheral surface of the inner side case 45.

摘要： PURPOSE:To prevent the drag of a pad at the braking release time so as to avoid the early wear of the pad, and reduce loss strokes at the beginning of the braking start time and improve responsiveness so as to avoid the degradation of a braking feeling. CONSTITUTION:A brake fluid is discharged from a cylinder part 1a by releasing the depression of a brake pedal 7 at the braking release time, and a clearance is formed between a pad 3 and a disc 8. Such a disc brake device is provided with a braking state detecting means 9 for detecting the depressed state of the brake pedal 7 so as to output a detection signal, and an electrically driven adjuster device 6 actuated on the basis of the detection signal of the braking state detecting means 9 and expanded so as to make a clearance small at the beginning of the braking start time is interposed between a piston 4 and the pad 3.

摘要： Some of the components of a parking brake mechanism are incorporated between an inner side case (45) and an outer side case (46), the two case (45) and (46) are combined by engaging lock holes (51, 51) and lock claws (55, 55), and an inner side auxiliary assembly (59) is formed. In this state, the diameter of circumscribed circle of the lock claws (55, 55) is configured to be smaller. Then, when the inner side auxiliary assembly (59) is incorporated in the cylindrical space (9a), the two lock claws (55, 55) are engaged with a lock concave (61) which is formed on the inner peripheral surface of the cylindrical space (9a) by making the two lock claws (55, 55) protrude greatly from the outer peripheral surface of the inner side case (45).

摘要： PROBLEM TO BE SOLVED: To reduce the degree of suppression of braking force mechanically generated based on operation of a parking lever 4a by hydraulic pressure led into a cylinder 6a following operation of a service brake without complicating a shape of each structure member. SOLUTION: A relay member 5a is oil-tightly inserted through a through hole 18a provided on a bulkhead 17a dividing the cylinder 6a and a retention hole 2a. A cylindrical liner member 23 having a side opening 24 is fitted and fixed in the retention hole 2a. A base end part of the relay member 5a is inserted in an inner diameter side of the liner member 23 through the side opening 24. A rolling surface of one roller 11a constructing one cam mechanism 15a is made in direct rolling contact on an base end surface 26 of the relay member 5a. A rolling surface of another roller 11b constructing another cam mechanism 15b is made in rolling contact with a bearing surface 25 provided on an inner surface existing at an opposite side of the side opening 24 with a camshaft 3a put therebetween in the liner member 23.

摘要： PROBLEM TO BE SOLVED: To obtain a duo-servo drum brake device exerting stable braking force without incurring complication of a cylinder body structure in an assembly of a wheel cylinder. SOLUTION: In a drum brake device, when one piston 32 is thrust back to an inside of a cylinder body 25 by control force from a control lever 37, a control valve 51 for regulating the inflow of a working oil into a pressurizing chamber 45 inside the cylinder body 25 is equipped with a valve seat 53 fitted, in a freely slidable manner, into a portion between an inlet 46 of the working oil in the pressurizing chamber 45 and the one piston 32, and a valve element 55 for closing a liquid passage 53a of the valve seat 53 when the valve seat 53 returns to a regular position in conjunction with a returning motion of the one piston 32. Besides, the valve seat 53 is provided with a sliding guide 53d protrusion/recess-fitted with the one piston 32. COPYRIGHT: (C)2010,JPO&INPIT
