Abstract
The utility model relates to an automotive part, in particular to a compound brake hub with an inner lining. The compound brake hub comprises a brake hub body and a hollow cylindrical inner ring lining, wherein the material of the brake hub body is cast steel, the material of the inner ring lining is cast iron, the inner ring lining is an integrated hollow cylinder, the inner ring lining is fixed on the inner ring of the brake hub body via at least two rows of bolts, and a radiating groove is arranged on the outer surface of the inner ring lining in a generatrix direction. The inner ring lining can be conveniently replaced for the compound brake hub with the inner lining disclosed by the utility model; and simultaneously, the radiating groove is arranged on the outer surface of the inner ring lining in a generatrix direction, and is capable of radiating and acting an anti-cracking effect..
Description
Technical field
The utility model relates to a kind of auto parts machinery, the compound brake hub of especially a kind of liner.
Background technique
Thereby brake hub is a kind of important automobile component of realizing heavy automobile brake that cooperates with automobile brake sheet.Heavy-duty car is because quality is bigger, and inertia is also bigger, and its brake member requires very high.When automobile under loading condition during frequently braking; High pressure friction between brake block and the brake hub can produce a large amount of heat, and the brake hub temperature is raise suddenly, causes the metallographic structure of brake hub, brake block to change; Produce return of goods phenomenon; Make the corresponding decline of intensity of brake hub, wearing and tearing aggravation, reduction of service life with hardness.Can cause brake failure when serious, lead to a disaster.For addressing this problem; People have conceived a lot of solutions; Such as Chinese patent 200720008859.2: braking automobile hub and 200820061991.4: these two kinds of brake hub of new brake hub all adopt double layer construction; But all adopt interference fit to fix internal and external layer, assembly technology is complicated, can not change the internal layer lining; 200720174166.0 brake hub, this brake hub also are to adopt double layer construction, but means of fixation has adopted rivet to fix, and so just cannot change the internal layer lining, causes waste.
Summary of the invention
The goal of the invention of the utility model is to overcome the defective that prior art exists, and realizes the compound brake hub of liner.
For realizing the foregoing invention purpose; The technological scheme of the utility model is: the compound brake hub of a kind of liner, comprise brake hub body and hollow cylindrical inner ring bushing, and the material of said brake hub body is a cast steel; The material of inner ring bushing is a cast iron; Said inner ring bushing is the integral type hollow cylinder, and inner ring bushing is passed through at least two rows' bolt on brake hub body inner ring, and said inner ring bushing outer surface generatrix direction is provided with radiating groove.
The cast steel of said brake hub body is the optional one of which of casting carbon steel material, cast low alloy steel material, casting special steel material.
Have the fixed hole that is fixedly connected with core wheel on the side annular plate of said brake hub body, the quantity of said fixed hole is 6 ~ 14.
The compound brake hub of a kind of liner; Comprise brake hub body and hollow cylindrical inner ring bushing; The material of said brake hub body is a cast steel, and the material of inner ring bushing is a cast iron, and said inner ring bushing is formed by two hollow semicolumn butt joints; Inner ring bushing is passed through at least two rows' bolt on brake hub body inner ring, and said inner ring bushing outer surface generatrix direction is provided with radiating groove.
The cast steel of said brake hub body is the optional one of which of casting carbon steel material, cast low alloy steel material, casting special steel material.
Have the fixed hole that is fixedly connected with core wheel on the side annular plate of said brake hub body, the quantity of said fixed hole is 6 ~ 14.
The beneficial effect of the utility model:
1. the compound brake hub of the liner of the utility model is the double layer construction of Spielpassung, assembles than is easier to, and can prevent that brake hub from bursting.
2. the compound brake hub of the liner of the utility model is provided with radiating groove at the outer surface generatrix direction, can dispel the heat and play the effect of anticracking.
3. the compound brake hub internal and external layer of the liner of the utility model can be changed inner ring bushing easily through bolt.
