Description
Technical field
The utility model relates to a kind of key components and parts of brake system of car, specifically a kind of automotive brake hub.
Background technique
Brake hub, also known as brake hub, is safety component crucial on automobile.Wheel of the bus, by the frictional force between brake block, is checked by brake hub, medium-sized and heavy vehicle all needs be equipped with brake hub.When driving, can brake hub be braked extremely important safely and reliably, if in emergency circumstances there is brake failure, will cause security incident, even cause car crash major break down.Therefore, very strict to brake hub requirements.
Always, automotive brake hub both domestic and external is all that cylinder iron cast inblock forms, its wear resistance and mechanical property good, casting technique is ripe, can molding large intricate casting, and price is lower, is applicable to producing in enormous quantities.But cast iron brake hub has following deficiency place; 1, cast iron density is high, and density reaches 7.3g/cm
3left and right, general truck needs 4 brake hubs, and the truck brake hub of a Φ 480 × 230mm weighs, 60Kg(is equivalent to the spring carrying capacity of 180 ~ 300Kg), therefore its unspringing weight is larger, obviously can increase vehicle oil consumption undoubtedly, reduce mobility performance, in addition, associated components dismounting, maintenance are more difficult; 2, the thermal conductivity of cast iron is poor, and the heat that during brake, friction produces distributes slowly, easily causes brake system to work because temperature rise is too high malfunctioning.3, cast iron brake hub is generally cast with molding sand, casting dimension accuracy, poor surface smoothness, and internal porosity pore is wayward, and the labor intensity of Foundry Production is high, and environmental pollution is larger.
Summary of the invention
Technical problem to be solved in the utility model is: for the deficiencies in the prior art, provides that a kind of lightweight, wear resistance and thermal diffusivity are good, the automotive brake hub of long service life.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of automotive brake hub, comprise cylindric brake hub body, described brake hub body is aluminum alloy brake hub body, and the inwall of described aluminum alloy brake hub body is compounded with circular wearing layer.
The utility model brake hub, its brake hub body is made up of aluminum alloy, and aluminum alloy density is low, significantly can alleviate the weight of brake hub, compared with the traditional cast iron brake hub of comparable size model, the utility model brake hub can loss of weight more than 50%, thus can capacity weight of the vehicle be increased, reduce oil consumption; The utility model brake hub passes through optionally local strengthening, at the wearing layer that the inwall compound of aluminum alloy brake hub body is circular, the wear resistance of the working surface of brake hub can be guaranteed, its wear resistance can reach more than 4 times of traditional cast iron brake hub, and reduce cost of material and the processing cost of brake hub, the thermal conductivity of aluminum alloy is also obviously better than cast iron simultaneously, therefore the wear resistance of the utility model brake hub and thermal diffusivity good, long service life, maintenance cost is low, that can to improve vehicle shortens braking distance by performance, improves the Security of automobile.
Described wearing layer is ceramic reinforcing material wearing layer.The wear resistance of ceramic reinforcing material wearing layer is better than cast iron, and dimensional accuracy is easy to control, and is conducive to the working life extending automotive brake hub.
The thickness of described wearing layer is 5 ~ 30mm.Select the ceramic reinforcing material wearing layer of suitable depth, ensureing, under the thermal conductivity of brake hub entirety, wear resistance and working life prerequisite, can reduce costs.
The thickness of described wearing layer is 5 ~ 20mm.Thickness is the wear-resisting needs that the wearing layer of 5 ~ 20mm can meet general brake hub.
Compared with prior art, the utility model has the advantage of: automotive brake hub disclosed in the utility model, its brake hub body is made up of aluminum alloy, aluminum alloy density is low, significantly can alleviate the weight of brake hub, realize the lightweight of brake hub, compared with the traditional cast iron brake hub of comparable size model, the utility model brake hub can loss of weight more than 50%, thus can increase capacity weight of the vehicle, reduces oil consumption; The thermal conductivity of aluminum alloy is also obviously better than cast iron, is conducive to the thermal diffusivity improving brake hub; The utility model brake hub passes through optionally local strengthening, at the wearing layer that the inwall compound of aluminum alloy brake hub body is circular, can guarantee the wear resistance of the working surface of brake hub, its wear resistance can reach more than 4 times of traditional cast iron brake hub, and reduces cost of material and the processing cost of brake hub.Therefore, the utility model brake hub is lightweight, wear resistance and thermal diffusivity good, long service life, maintenance cost is low, and that can improve vehicle shortens braking distance by performance, improves the Security of automobile.Employing wearing layer of the present utility model carries out the mode of optionally local strengthening to surface of contact, be also applicable to brake disc and other friction catch occasions.
