Definitions

• the present invention relates to a disk brake which automatically adjusts a brake clearance between a brake pad and a brake disk, and particularly to a brake operating device using a hydraulic bolt. And a disk brake provided with a hand brake device and an automatic brake clearance adjustment device.
• the disk brake has a small brake clearance between the brake pad and the brake disk. If the brake clearance force increases due to wear of the brake pad, etc., it is necessary to adjust it to an appropriate clearance.
• an automatic adjustment device that automatically adjusts the brake clearance to keep it constant even if the brake pad wears out must be used. Must follow.
• a thrust bearing and an elastic body may be used so that the force is transmitted from the biston to the adjustment nut.
• the biston is advanced to the brake disc side by hydraulic pressure, and the force from the piston is transmitted to the adjustment nut via the elastic body and the thrust bearing.
• the nuts are cultivated. In this way, by adjusting the initial position of the piston, the brake clearance is adjusted.
• An object of the present invention is to provide a disk brake which solves such a problem, and when a fixed amount of elastic body is compressed between a syllable nut and a bone, the present invention aims to provide a disk brake.
• a slope is provided around the first time when the elastic body is compressed by a certain amount to prevent the adjustment nut from rotating when the elastic body is compressed by a certain amount, so as to prevent over-adjustment of the brake clearance.
• 1 is a caliper
• 2 is a reaction portion of the caliper
• 5 is a cylinder of the caliper 1 that opens to the reaction portion 2
• 4 is a protrusion and a recess in the cylinder 3.
• a freely fitted piston 5 is a seal ring interposed between the cylinder 3 and the piston 4.
• the screw hole 4 is formed with a hole ⁇ opening on the closed end side in the cylinder 3, and the caliper 1 is formed with a hole 7 opening in the cylinder 5.

• Reference numeral 9 denotes an eccentric cam supported by the caliper 1
• reference numeral 10 denotes a push rod 'interposed between the eccentric force 9 and the base end 8a.
• the eccentric cam 9 is rotated by operating a parking handbake (not shown) and a rake repeller to displace the spindle 8 to the left via the push rod 10. It has become.
• 8 d is a step formed at the base end 8 a by forming the flat surface 8 c.
• a plate 11 that can move in the axial direction and does not rotate in the circumferential direction is fitted to a portion of the base end portion 8 provided with the plane 8c. This plate 11 has projections 14 that fit slidably into holes 15 in panel receivers 12.
• OMPI Is formed.
• the projections 14 prevent the plate 11 from rotating around the panel receiver 12 in the circumferential direction.
• Panel receivers 1 and 2 are fixed to carrier 1.
• a minute gap 15 is formed between the base 12 a of the panel receiver 12 and the plate 11 so that the plate 11 can move in the axial direction of the spindle 8.
• Reference numeral 1 denotes a compression coil spring interposed between the tip of the panel receiver 12 and the plate 11.
• An adjustment nut 17 is movably connected to the screw portion 8 of the spindle 8.
• the adjustment nut 17 integrally has a flange 18 at an intermediate portion.
• a ring-blade-shaped pressing body 19 is screwed into the hole 4 of the screw 4.
• the pressing body 19 is located closer to the opening end of the hole ⁇ than the adjustment nut 17 is.
• Reference numeral 23 denotes a ring located between the flange 18 and the plate 21, and the ring 23 is fixed to the inner surface of the hole ⁇ .
• An annular concave portion 25 extending in the circumferential direction is formed between the ring 23 and the inclined surface 24 of the hole ⁇ .
• the periphery of the flange 18 is loosely fitted in the recess 25. As a result, the flange 18 can be slightly moved in the axial direction of the spindle 8 in the recess 25.
• the opposed surfaces of the ring 25 and the ring 25 are formed with inclined surfaces 18a and 23a which are pressed against each other.
• reference numeral 2 denotes an oil chamber formed between the piston 4 and the cylinder 3.
• the brake pad and the brake disk are omitted, but these are arranged between the screw-on 4 and the reaction part 2.
• the advance output of the piston 8 is changed to the flange 18 via the pressing body 19, the elastic body 20, the plate 21 and the thrust bearing 22.
• the adjustment nut 17 is rotated by the advance output of the piston 8, and is slightly moved and adjusted to the left.
• the compression of the body 20 and the rotation of the adjustment nut 17 are restricted.
• the facing portion of the flange 18 of the adjustment nut 17 with the ring 23 in this embodiment, the inclined surface 18). a, 23a) may be provided with teeth that bite each other when they come into contact with each other. As a result, the adjusting action of the narrative is stopped. After that, even if the hydraulic pressure is further applied to the oil chamber 2 ⁇ ⁇ to advance the piston 4, the adjusting nut 17 does not rotate.
• the adjusting nut and the piston are provided with the inclined surfaces that are pressed against each other when the elastic body is compressed by a certain amount, so that the adjustment is performed when the elastic body is contracted by a certain amount.
