Abstract
The utility model discloses an automobile bimetal brake hub, consisting of a brake hub inner ring made of cast iron and a brake hub body made of cast steel. The outer wall of the brake hub inner ring and the inner wall of the brake hub body are presented in metallurgical bonding. The automobile bimetal brake hub has high mechanical strength, which can effectively prevent the breakage in early stage. The inner ring of the brake hub has good wear resistant. The brake performance is strong. The brake hub is easy to be manufactured with long service life. The brake safety of the motor vehicles can be secured which is favorable for security.
Description
Technical field
The utility model relates to the break of Motor Vehicle, more specifically relates to a kind of automobile double metal braking hub.
Background technique
The braking hub is the critical component in the motor vehicle brake, the braking hub is commonly called as brake hub, existing Motor Vehicle braking hub majority adopts iron casting, processes, because overload, hypervelocity phenomenon that the truck ubiquity is serious, make its braking hub can not satisfy usage requirement, breaking in early days and damaging appears in the braking hub, has serious potential safety hazard.
In order to solve the shortcoming of existing cast iron braking hub, people have proposed many improvement technological schemes, strive solving from structure or material aspect, but effect is not good enough, as, notice of authorization day is on April 23rd, 2008, notice of authorization number is CN 201050565Y, name is called " brake hub that has outer tension ring ", disclosed technological scheme, this brake hub is made up of brake hub body and an outer tension ring, has at least one stress vertically and eliminate seam on the brake hub body, and outer tension ring transition fit is enclosed within on the brake hub body.The outer tension ring of this brake hub because outer tension ring is that transition fit is enclosed within on the brake hub body, axially has stress simultaneously and eliminates seam on the brake hub body, the mechanical strength of this brake hub is descended greatly, difficulty of processing strengthens greatly, and is fragile in the use, is difficult to promote.For this reason, remain further to explore and improve.
Summary of the invention
The purpose of this utility model: in order to overcome the deficiency of above-mentioned braking hub, and provide a kind of automobile double metal braking hub.
The technical solution of the utility model is achieved in that a kind of automobile double metal braking hub, and it is made up of the braking hub inner ring of cast iron and the braking hub body of cast steel, and the outer wall of braking hub inner ring is a metallurgy combination with the inwall of braking hub body.
Described braking hub inner ring is cylinder type, and the thickness of braking hub inner ring is 4-15mm, and the material of braking hub inner ring is HT20-40; The thickness of described braking hub body is 8-20mm.
Described braking hub body connects base plate by the braking hub and braking hub outer ring connects as one by the welding band, and the outer wall of braking hub inner ring is a metallurgy combination with the inwall of braking hub outer ring.
Automobile double metal braking hub of the present utility model, during production, first cast steel moulding braking hub body, back cast iron moulding braking hub inner ring, the surface of contact that makes both is a metallurgy combination, carries out fine finishing by the technological scheme of design thereafter.
The beneficial effects of the utility model: automobile double metal braking hub of the present utility model is compared with the existing brake hub that has outer tension ring, automobile double metal braking hub mechanical strength of the present utility model is big, effectively control is broken in early days, braking hub inner ring wear resistance is good, braking ability is strong, easy processing, long service life, make the brake safe of motor vehicle secure, favourable safety.
