Description
Technical field
The utility model belongs to forklift equipment technical field, relates to a kind of brake parts, particularly a kind of circular disc on forklift.
Background technique
Forklift has another name called loader, a kind of restoration in earth-rock construction machinery being widely used in the construction projects such as highway, railway, building, water power, harbour, mine, it is mainly used in the bulk materials such as shovel dress soil, sandstone, lime, coal, also can make slight shovel to ore, pan soil etc. and dig operation.The different auxiliary working apparatus that changes the outfit also can carry out bulldozing, lifting and unclassified stores be as the handling operation of timber.At road, particularly in Expressway Construction, loader is used for that filling out of subgrade engineering is dug, the gathering materials and the operation such as charging of asphalt and coagulating cement borrow pit.Can carry out in addition pushing soil, scrape plane earth and drawing the operations such as other machineries.Because loader has, operating speed is fast, efficiency is high, mobility is good, operate the advantages such as light, and therefore it becomes one of main machine of restoration in earth-rock construction in engineering construction.
Break is in order to produce the parts hindering vehicle movement or movement tendency braking force in braking system.Break in forklift, except various retarding device, is nearly all the friction brake utilizing the friction of fixed element and rotatable member working surface to produce braking moment.At present, the friction brake extensively adopted can be divided into drum-type and the large class of disc type two according to the difference of rotatable member.Difference between them is: the rotatable member in drum type brake friction pair is brake drum, with its cylndrical surface for working surface; Rotatable member in disk type braker friction pair is discoid brake disc, with its end face for working surface.Circular disc is the fricting couple piece of disk type braker, except having as except the strength and stiffness required for component, also should have friction factor high and stable as far as possible, and suitable wear resistance, heat resistance, thermal diffusivity and thermal capacity etc.
China's patent (notification number: CN204553625U; Publication date: 2015-08-12) disclose a kind of automobile brake disc, comprise inside brake disk body, outer braking disk body and anchor hub, inside brake disk body, outer braking disk body and anchor hub are circle, the periphery of inside brake disk body and outer braking disk body is provided with continuous print friction protrusion, the lower surface of inside brake disk body and the upper surface of outer braking disk body is radial is vertically provided with groove, groove is provided with multiple radiation hole; Outer braking disk body is provided with anchor hub, and anchor hub comprises hub section and supporting walls section, and supporting walls section and vertical direction are 1.5 ° of angles, and the joint of supporting walls section and outer braking disk body is provided with slotting groove, and slotting groove depth is 5mm; The thickness of inside brake dish is thinning gradually from outside to inside along its direction, center of circle, between inside brake disk body and outer braking disk body, reinforced layer is set, the upper surface of reinforced layer and lower surface are all provided with many stiffening ribs along inside brake dish axial radiation shape, and reinforced layer and stiffening rib form heat dissipation channel.
Brake disc can produce friction dust in braking process, to get up increasing friction force in automobile brake disc disclosed in above-mentioned patent by arranging friction projection, and a large amount of dust produced that rub all directly drop and spread, and do not utilize the cleaning of air.
Summary of the invention
The problems referred to above that the utility model exists for existing technology, provide a kind of circular disc on forklift, technical problem to be solved in the utility model is: effectively carry out dust-proof while of how improving forklift circular disc braking effect.
The utility model object realizes by following technical proposal:
A circular disc on forklift, comprises discoid body, the middle part of described body offer along body shaft to mounting hole, it is characterized in that, a side of described body offers some blind holes, another side offers some radiation holes.
Its principle is as follows: the circular disc in the technical program is used for the braking of forklift, the installation that mounting hole is used for body is fixed, the side of body is used for rubbing with brake block producing friction brakes, this side offers some blind holes, the dust produced by rubbing can enter into blind hole and store, and can not arbitrarily spread, thus avoid the wearing and tearing that the pollution of air and dust cause other component.The radiation hole that body another side offers can play thermolysis to body, ensures braking effect, improves the working life of circular disc.
Additionally by the concave point that blind hole and radiation hole are formed at the rubbing surface of body, can friction factor be increased, improve braking effect.
As preferably, blind hole one end has opening, and the other end is closed and extended to body interior, radiation hole is the through hole running through body, radiation hole is near the middle part of body, and the axial direction of radiation hole can be identical with the axial direction of body, also can be obliquely installed relative to the axial direction of body; Blind hole is near the edge of body, radiation holes all so is all positioned at the regional extent that blind hole surrounds, the dust that such friction produces can not result in blockage to radiation hole, ensure great heat radiation effect, and the dust produced that rubs under the influence of centrifugal force can be entered into blind hole, prevent random diffusion, contaminated air and cause other parts wear.
In the above-mentioned circular disc on forklift, described blind hole along the circumferential uniform intervals distribution of body and described blind hole near the edge of described body.In circular disc rotation process, because centrifugal force makes fricative dust spread to surrounding, blind hole, along the circumferential uniform intervals distribution of body, can ensure that all dust can both enter into blind hole smoothly and go like this.
In the above-mentioned circular disc on forklift, the opening of described blind hole has by the guide surface of the side of body to the hole wall inclination extension of blind hole, and described guide surface is formed uncovered.The opening of blind hole is uncovered shape, is convenient to dust and enters into blind hole smoothly.
In the above-mentioned circular disc on forklift, the inside of described body has the ring cavity along body circumference, and described ring cavity is near the edge of described body, and all described blind holes are all connected with described cavity.Dust is stored by ring cavity.
In the above-mentioned circular disc on forklift, described blind hole helically type and helical centre is consistent with the axis of described body.
Compared with prior art, in the utility model, the side of body is used for rubbing with brake block producing friction brakes, this side offers some blind holes, the dust produced by rubbing can enter into blind hole and store, and can not arbitrarily spread, thus avoid the wearing and tearing that the pollution of air and dust cause other component.
