Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of break, particularly a kind of caliper disc brake.
Background technique
Break is the mechanical parts that make the movement parts in the machinery stop or slowing down.Break mainly is made up of brake bracket, brake component and Effector etc.Break can be divided into outer block brake, interior shoe brake, band brake, the caliper disc brake etc. embraced again by the structural type of brake component.Wherein JB/T 10917-2008 has stipulated term and definition, pattern, technical requirements, test method and the inspection rule etc. of caliper disc brake.
Caliper disc brake comprises caliper, piston, friction plate assembly.All have in the caliper and be oil pocket cylindraceous, the opening in two groups of chambeies is relative up and down.Caliper is opened the friction plate assembly is installed in the retaining, has the gap that is used to install brake disc between two friction plate assemblies.Piston is arranged in the oil pocket, can the fuel-displaced lumen pore end in Shen and be resisted against on the friction plate assembly in the outer end of piston.
At present, the caliper disc brake of domestic loader dry type ransaxle configuration because the filler opening position of break is arranged in brake assembly, bottom, causes the break braking weak easily, even causes the catastrophe failure of braking failure.As depicted in figs. 1 and 2; Caliper disc brake mainly is made up of break caliper 1, piston 2, oil cylinder cover, friction plate assembly 7, fuel inlet neck 3, deflating valve 10, oil inlet pipe assembly 14 etc.; Wherein brake fluid is the working medium of break, realizes the braking function of break through compression brake liquid.When the filler opening position was positioned at break lower oil cylinder cover or break medium position, under the frequent operation operating mode of braking, break oil cylinder inside brake liquid temp raise; Along with the rising of brake fluid temperature, will produce more gas and nest in the break oil cylinder and amass in the top of break and can't discharge, cause braking weak; Sometimes make break produce back pressure (after promptly loosening the brake; The braking system internal pressure can not get discharging fully, still residual overbottom pressure), cause existing extra friction overheated between friction plate and the brake disc; Brake fluid temperature raises, and then produces more gas in the break; When gas was increased to a certain limit in the oil cylinder, in the moment of brake off, pressurized gas were shifted the fluid in the break onto the assistor lubricating cup, caused brake fluid ejection assistor lubricating cup, and then caused the catastrophe failure of braking failure.
The model utility content
The purpose of the utility model is exactly that the filler opening position that is directed against present caliper disc brake is arranged in brake assembly, bottom; Cause the break braking weak easily; Even the technical problem of braking failure, provide a kind of braking ability more safe and reliable caliper disc brake.
The utility model is achieved in that
A kind of caliper disc brake; Comprise caliper, fuel inlet neck, deflating valve; Each side establish upper cylinder and following oil cylinder at caliper, the oil pocket of upper cylinder of caliper the same side and following oil cylinder is communicated with by brake circuit between cylinder, in the middle of caliper, is provided with the friction plate assembly; Upper cylinder all is connected with the friction plate assembly with the piston outer end of following oil cylinder, and fuel inlet neck is communicated with the oil pocket top of upper cylinder.Through this structure setting; If in oil cylinder, produced gas; Gas can be discharged brake cylinder through fuel inlet neck and in-line when take-off the brake, gas can not amassed by nest in oil cylinder, effectively solves gas nest collection in oil cylinder and causes the weak problem of braking; Prevent the moment at brake off simultaneously, pressurized gas are shifted the fluid in the break onto the assistor lubricating cup, cause brake fluid ejection assistor lubricating cup, and then cause the catastrophe failure of braking failure; This structure setting also can not produce back pressure at oil cylinder nest pneumatosis body exceedingly and cause break brake off fully.
The above caliper top is provided with the last brake circuit that is communicated with caliper left and right sides upper cylinder; Said caliper bottom is provided with the following brake circuit that is communicated with oil cylinder under the caliper left and right sides, and said fuel inlet neck is arranged on caliper one side and is connected with the oil pocket top of upper cylinder.Can the brake cylinder of the left and right sides be communicated with through brake circuit up and down, thus can be only fuel inlet neck, simplified structure be set in a side of caliper.
The above-described brake circuit of going up is arranged in the caliper, and following brake circuit also can be arranged in the caliper.Brake circuit is arranged in the said caliper up and down, can prevent that brake circuit receives the exterior object collision and damages up and down, improves the safety reliability of whole brake circuit.
The above upper cylinder comprises the cylinder cap that oils, and said fuel inlet neck is arranged on described upper cylinder and covers.
Above-described fuel inlet neck is positioned at the top at the center of the cylinder cap that oils, and adopts eccentric design, and with the distance at the center of the cylinder cap that oils be that A value is 10-25mm.
The top that above-described deflating valve is arranged on fuel inlet neck is connected with the described brake circuit of going up.
Below also comprise the mouth of draining the oil, the said mouth of draining the oil is positioned at the below of said oil cylinder down and links to each other with said brake circuit down.
Above-described caliper disc brake also comprises dust-proof cover, described dust-proof cover be provided with said oil pocket opening and around with the outside of described piston.Prevent that dust from getting into the fitting surface of piston and oil pocket chamber wall.
The both sides up and down of above-described caliper are symmetrical set the plug screw that is useful on the sealing brake circuit.Caliper is provided with the plug screw of the opening of leaving on the caliper surface when being used to seal the processing brake circuit.
The advantage of the utility model:
Caliper disc brake passes through break filler opening position; Inner brake circuit is optimized design, and fuel inlet neck is arranged on upper cylinder or the upper cylinder side of covering, and fuel inlet neck is communicated with the oil pocket top of upper cylinder; All adopt built-in oil circuit; Automatically discharge brake inside remaining (or brake fluid high temperature produces) gas, reduce because of the break back pressure causes that the extra friction between brake disc and the friction plate is overheated, thereby reduce the brake inside brake fluid temperature; And can avoid or reduce because of the assistor oil spout causes the misfunctioning of brake fault, improve the reliability of braking system greatly.
