Abstract
The utility model provides a kind of brake hub, comprise the brake hub body of cast steel, the neck bush of the hollow cylindrical of gray cast iron is provided with in described brake hub inner body wall, described neck bush has four quadrant cylinders to assemble, described neck bush is fixed on brake hub body inner ring by the bolt of at least one row, the outer surface of the described brake hub body of a part is surrounded by one deck steel casing, and the outer surface of the described brake hub body of remainder is provided with radiating groove.The brake hub that the utility model provides, is provided with back-up coat at the outboard sidewalls of brake hub body, prevents brake hub body from ftractureing; The outer side wall of brake hub body is also provided with radiating groove, perfect heat-dissipating.
Description
Technical field
The utility model relates to a kind of auto parts machinery, especially a kind of brake hub.
Background technique
Brake hub a kind ofly coordinates with automobile brake sheet thus realize the important automobile component to automobile brake.Full-sized car due to quality comparatively large, inertia is also comparatively large, and its brake member requires very high.When automobile in load conditions frequently braking time, high pressure friction between brake block and brake hub can produce a large amount of heat, brake hub temperature is raised suddenly, cause brake hub, the metallographic structure of brake block changes, produce and degenerate, make the decline corresponding to hardness of the intensity of brake hub, wearing and tearing aggravation, reduction of service life.Can brake failure be caused time serious, lead to a disaster.
In view of this, special proposition the utility model.
Model utility content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of outboard sidewalls at brake hub body is provided to be provided with back-up coat, the outer side wall of brake hub body is also provided with radiating groove, under the prerequisite preventing brake hub body from ftractureing, perfect heat-dissipating.
For solving the problems of the technologies described above, the basic conception of the utility model employing technological scheme is:
A kind of brake hub, comprise the brake hub body of cast steel, the neck bush of the hollow cylindrical of gray cast iron is provided with in described brake hub inner body wall, described neck bush is assembled by four quadrant cylinders, described neck bush is fixed in brake hub inner body wall by the bolt of at least one row, when the size after neck bush Split type structure direct-assembling is less than the size of the inwall of brake hub body, between Split type structure, adopt link grafting; The outer surface of described brake hub body is surrounded by one deck steel casing, and the bottom surface of described brake hub body has radiation hole.
Preferably, described brake hub body is the brake hub body of casting carbon steel.
Preferably, described brake hub body is the brake hub body of cast low alloy steel.
Preferably, described brake hub body is the brake hub body of casting special steel.
After adopting technique scheme, the utility model compared with prior art has following beneficial effect: be provided with back-up coat at the outboard sidewalls of brake hub body, prevents brake hub body from ftractureing; The outer side wall of brake hub body is also provided with radiating groove, perfect heat-dissipating.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model brake hub.
In figure: 1-steel casing, 2-brake hub body, 3-bolt, 4-neck bush, 5-radiation hole
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, to help understanding content of the present utility model.
As shown in Figure 1, a kind of brake hub, comprises the brake hub body 2 of cast steel, described brake hub body 2 inwall is provided with the neck bush 4 of the hollow cylindrical of gray cast iron, prevent brake hub body 2 from ftractureing, hollow-core construction effectively can reduce the overall weight of brake hub simultaneously, strengthens stability.Described neck bush 4 is assembled by four quadrant cylinders, also can be made up of two semicylinders and form, or neck bush 4 is a kind of all-in-one-piece hollow cylinder body mechanism.When the cylindrical body of neck bush 4 is package assembly, each Split type structure for assembling is connected by link, distance between Split type structure can be adjusted according to the size of brake hub body 2 inwall, as long as ensure that Split type structure is corresponding, structural stability when being assembled into one.Such as, when the inwall of the size after Split type structure direct-assembling (i.e. voidlessness between adjacent Split type structure) and brake hub body 2 adapts, then intermediate connector need not be used; When the size after Split type structure direct-assembling (i.e. voidlessness between adjacent Split type structure) is less than the size of the inwall of brake hub body 2, link grafting can be adopted between Split type structure, all there is space (space is in the both sides up and down of plug connector) between all adjacent Split type structures, expand the cylinder diameter of neck bush 4 Split type structure to adapt to the size of brake hub inner body wall.
Described neck bush 4 is fixed on brake hub body 2 inwall by the bolt 3 of at least one row, and the outer surface of described brake hub body 2 is surrounded by one deck steel casing 1, and the bottom surface of described brake hub body 2 has radiation hole 5.
Described brake hub body 2 is the brake hub body 2 of casting carbon steel, take carbon as the cast steel of main alloy element also containing other elements a small amount of.Adopt the high carbon steel that carbon containing is greater than 0.5%.Along with the increase of carbon content, the intensity of casting carbon steel increases, and hardness improves.Casting carbon steel has higher intensity, plasticity and toughness, and cost is lower.
Preferably, described brake hub body 2 is the brake hub body 2 of cast low alloy steel, the cast steel containing alloying elements such as manganese, chromium, copper.Alloying element total amount is generally less than 5%, has larger impact toughness, and obtains better mechanical property by heat treatment.Cast low alloy steel has preferably usability than carbon steel, can reduce part quality, improves working life.
Preferably, described brake hub body 2 is the brake hub body 2 of casting special steel, containing the high manganese steel ability impact wear of manganese 11% ~ 14%.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
