The invention discloses a fixed caliper disc type brake with an automatic gap regulating device. The fixed caliper disc type brake comprises brake calipers and a brake disc, and further comprises a friction ring, wherein the brake calipers are crossed at the two sides of the brake disc; an oil inlet and a liquid runner are formed in the brake calipers; the two sides, in the axial direction of the brake disc, of the brake calipers are symmetrically provided with pistons; the pistons are provided with brake blocks; each piston comprises a narrow part and a wide part; the inner wall of the friction ring is movably arranged on the narrow part of each piston in a sleeving mode; the outer wall of the friction ring is in interference fit with the inner walls of the brake calipers; the narrow part of each piston is further provided with a clamping slot; each clamping slot is provided with a clamping ring; and a tension spring is arranged between the brake calipers and the narrow parts of the pistons. According to the scheme, the fixed caliper disc type brake has the effects that: the friction ring is arranged on the inner walls of the brake calipers; when a gap between the brake blocks and the brake disc is increased due to the fact that the brake blocks are worn, by virtue of hydraulic action, a moving distance of the friction ring is equal to the increased gap between the brake blocks and the brake disc, so that the automatic regulation on the gap between the brake blocks and the brake disc is realized.
Description
Technical field
The present invention relates to a kind of disc brake with fixed caliper with gap automatic regulating device.
Background technique
Rotatable member in disk type braker friction pair is with the rosette of end face work, is called brake disc.Friction element produces braking from both sides clamping brake disc.Fixed element then has various structures form, disk type braker can be divided into caliper disc and complete-disc two class substantially.
Caliper disc brake can be divided into by the structural type of brake calipers determines caliper disc and floating caliper type disc two kinds, in disc brake with fixed caliper, brake slipper and brake disc friction realize the braking of brake disc, in order to ensure the normal traveling of automobile, best brake clearance should be kept between brake slipper and brake disc, traditional disc brake with fixed caliper in use for some time, brake slipper will produce certain wearing and tearing under the effect of long-term frictional force, thus the gap of causing between brake slipper and brake disc is increased, the serious normal traveling that will have influence on automobile.
Summary of the invention
The invention is intended to provide a kind of brake clearance that can automatically adjust between brake slipper and brake disc, ensure the disc brake with fixed caliper with gap automatic regulating device of automobile normal running.
The disc brake with fixed caliper with gap automatic regulating device in this programme, comprise brake calipers and brake disc, brake calipers is across in brake disc both sides, brake calipers is provided with filler opening and flow channel for liquids, filler opening and flow channel for liquids communicate, brake calipers is positioned at the axial bilateral symmetry of brake disc and is furnished with piston, piston place is provided with brake slipper, also comprise friction ring, piston comprises narrow portion and wide portion, the inwall kink of friction ring is in the narrow portion of piston, outer wall and the brake calipers inner surface heat of friction ring overlay conjunction, the narrow portion of piston also offers draw-in groove, draw-in groove place is provided with snap ring, extension spring is provided with between brake calipers and the narrow portion of piston, extension spring one end and brake calipers offset, the narrow portion of the extension spring the other end and piston offsets, the active force of extension spring is less than the active force between friction ring and brake calipers.
The principle of this programme is: during braking, brake fluid enters from the filler opening of brake calipers, promote piston driving brake slipper through flow channel for liquids to move to direction, brake disc place, when brake slipper and brake disc reach compaction, the end face of snap ring just in time offsets with the end face of friction ring, now brake disc is braked under the effect of both sides brake slipper, when brake slipper uses a period of time to occur wearing and tearing, brake slipper is driven to move at hydraulic pressure lower piston, until the end face of snap ring and the end face of friction ring offset, brake slipper now will and brake disc between also there is certain distance, under the continuous action of hydraulic pressure, the active force that snap ring will make friction ring overcome and between brake calipers inwall to the active force of friction ring, thus make friction ring continue to move to direction, brake disc place together with brake slipper, until brake slipper and brake disc press, after braking process terminates, piston resets under the effect of extension spring, until the wide portion of piston and friction ring offset.
Active force due to extension spring can not make friction ring overcome active force between itself and brake calipers inwall, therefore friction ring will remain on new position, and then make piston also remain on new position, when again braking, when snap ring end face and friction ring end face offset, brake slipper and brake disc also will reach compaction, thus realize the automatic adjustment in gap between brake slipper and brake disc.
The effect of this programme is: by arranging friction ring at brake calipers inwall, when brake pads wear makes the gap between brake slipper and brake disc increase, the distance of friction ring movement is made to equal the gap increased between brake slipper and brake disc by hydraulic pressure, after braking completes, friction ring and piston are in new position, under this position, the range recovery between brake slipper and brake disc is initial distance, thus achieves the automatic adjustment in gap between brake slipper and brake disc.
Further, in order to prevent brake fluid to external leakage, wide portion and the brake calipers cooperation place of piston offer the first groove, are provided with the seal ring preventing brake fluid from leaking in the first groove.
Further, in order to improve the heat dissipation potential of brake calipers, simultaneously in order to make the production and processing of break convenient, brake calipers also offers the radiating fin increasing heat diffusion area, radiating fin has tapering.
Further, in order to the burr that prevents from brake calipers end face connecting part from existing producing in course of working and prevent the stress of brake calipers end face connecting part from concentrating, the end face connecting part of brake calipers offers circular arc chamfering.
