Abstract
The utility model relates to a brake disk, in particular to a brake disk for a tractor. The brake disk comprises a disk body comprising dual-friction steel and paper bases. The paper bases are respectively arranged at the peripheries of the outer circles of the positive surface and the negative surface of the dual-friction steel, and an assembling hole is arranged at the middle of the dual-friction steel. Inner teeth are arranged at the side wall of the assembling hole. Double arc slots are engraved on the surfaces of the paper bases, and radial slots are arranged at the middles of the double arc slots. The radial slots contact the double arc slots. Oil passing holes are also arranged between the paper bases and the assembling hole. The utility model has the advantages of high radiation, convenient assembly and long use life.
Description
Technical field
The utility model is a kind of braking, particularly is used for the brake disc of tractor.
Background technique
The brake disc that is used for tractor of the prior art, assembly precision is not high, simultaneously friction factor is low, the product loss is fast, the friction disk heat dispersion is poor, can't be effectively discharge during the heat utmost point that produces, cause friction plate to reduce working life.
Summary of the invention
Model utility mainly is to solve the deficiencies in the prior art, provides a kind of heat dissipation rate fast, the brake disc that is used for tractor that quality of fit is high.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of brake disc that is used for tractor, comprise disk body, described disk body comprises antithesis steel disc and paper substrate, the antithesis steel disc) double-edged outer circumferential edges is respectively equipped with paper substrate, and the centre of antithesis steel disc is provided with pilot hole, and the sidewall of pilot hole is provided with internal tooth, be carved with two arc grooves on the described paper substrate surface, the centre of two arc grooves is provided with equally distributed radial groove, and described radial groove contacts with two arc grooves, described paper substrate and pilot hole also be provided with oil-through hole.
As preferably, described paper substrate and antithesis steel disc are bonding, and the described pair of arc groove intersects even distribution mutually by the arc groove of two groups of different direction and form, and described radial groove has 6, and radial groove distributes on the surface of paper substrate uniformly; Described oil-through hole has 5, and oil-through hole is evenly distributed on the antithesis steel disc.
As preferably, the interior number of teeth in the described pilot hole is 22, and described oil-through hole is pressed close to mutually with the inner circumference of paper substrate.
Therefore, the brake disc that is used for tractor that the utility model provides, the thermal diffusivity height is convenient to assembling, long service life.
