Abstract
The utility model relates to a mine dump truck wet type multi-disc brake, which belongs to the field of mine dump truck brakes. The mine dump truck wet type multi-disc brake is provided with sealing grooves and a guiding belt groove on the inner side of a driving brake piston, wherein a sealing ring and a guiding belt are respectively arranged in the grooves, an inner sealing groove and an outer sealing groove are crossly arranged, and an inner guiding belt groove and an outer guiding belt groove are crossly arranged. The mine dump truck wet type multi-disc brake solves the problem of the machine adding space through improving the sealing structure mode of a wet type multi-disc brake driving brake piston, reduces the process difficulty of driving brake piston sealing component grooves, and solves the problems of special-purpose tools and measuring tools, thereby leading the structure of the whole wet type multi-disc brake to be simpler and easy to process, being convenient to dismount and mount sealing elements, and increasing the production efficiency.
Description
Technical field
The utility model relates to the quarry tipper wet multi-disc brake, belongs to quarry tipper break field.
Background technique
At present, the quarry tipper break of sale and use mostly is drum brake, disk type braker and wet multi-disc brake on the market.Wherein wet multi-disc brake is a fully hydraulic driven, can save pneumatic element, and is simple and compact for structure, can not freeze winter, the maintenance that need not to discharge water, and valve and pipeline can corrosions, the braking reliability improves, totally-enclosed water proof and dust proof, and braking ability is stable, wear-resistant, long service life need not adjusted, radiating effect is good, and the friction pair temperature reduces significantly, just can change friction disk quantity under the prerequisite that does not increase radial dimension, and can regulate braking moment, be easy to realize seriation, standardization.Because wet multi-disc brake has above characteristics, using on quarry tipper has become a kind of development trend.Yet, complex structure, processing difficulties also is the main feature of wet multi-disc brake.Its complex structure, processing difficulties are mainly reflected on the service brake piston sealing structure, and traditional service brake piston seal groove is opened on driving brake piston end cap.Because function needs and the restriction of structural configuration, the sectional area of service brake piston is very little, causes the sectional area of the piston groove that the service brake piston end covers also very little.Because the space, cross section of piston groove is narrow and small, the black box groove of its both sides needs special-purpose cutter to solve the withdrawing problem, also needs the measurer of design specialized to measure, and is difficult to guarantee requirement on machining accuracy.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the quarry tipper wet multi-disc brake of convenient processing.
Technical solution: the utility model is opened seal groove and guiding trough of belt in driving brake piston inboard, and seal ring and guidance tape are installed respectively in groove, opens seal groove and guiding trough of belt in the driving brake piston outside, and seal ring and guidance tape are installed respectively in groove; Inner seal groove and outside seal groove are crisscross arranged, and inboard guiding trough of belt and outside guiding trough of belt are crisscross arranged.
The utility model is to have now under the constant situation of overall plan and boundary dimension, cover at the driving dog point and not reprocess black box groove (that is: OD seal groove, OD guiding trough of belt, OG seal groove, OG leads trough of belt), but the black box groove is opened on the brake piston of driving a vehicle.Darker OD, OG seal groove and the more shallow guiding trough of belt in service brake piston medial and lateral is interspersed.Groove all is designed to U type structure according to the installation needs of black box.
The utility model is by the improvement to wet multi-disc brake service brake piston sealing structure form, and the machine that solved adds space problem, reduces the difficulty of processing of service brake piston seal assembly groove, solves dedicated tool and measurer problem.Thereby make the structure of whole wet multi-disc brake simpler, be easy to processing, be convenient to seal element dismounting, improved manufacturing efficiency.
Description of drawings
Fig. 1 is a wet multi-disc brake assembly plan view;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the partial enlarged drawing I of Fig. 2.
Embodiment
The utility model is opened OD seal groove and guiding trough of belt in driving brake piston 3 inboards, and OD seal ring 7 and guidance tape 8 are installed respectively in groove, opens OG seal groove and guiding trough of belt in the driving brake piston outside, and OG seal ring 6 and guidance tape 5 are installed respectively in groove.And darker OD, OG seal groove and the more shallow guiding trough of belt in medial and lateral is interspersed as shown in the figure.
When implementing service brake, hydraulic system applies service brake pressure by service brake liquid inlet to service brake piston 3, and service brake piston 3 compresses liner 1 and friction plate 2 produces friction, realizes service brake.Service brake finishes the post-braking system pressure release, resets at the effect down train brake piston 3 of Returnning spring 4.Play good sealing pressurize effect at whole braking process middle rolling car braking sealing assembly.
