Description

Cooling hub

Technical Field

The invention belongs to the technical field of automobile accessories, and particularly relates to a cooling hub.

Background

The automobile hub is a common automobile basic accessory, and at present, the automobile hub can only realize the connection function of a tire and an axle; the water spray cooler is an active brake pad cooling device, but is only suitable for large-scale load-carrying vehicles, and cannot be used on household commercial automobiles due to the problems of volume, appearance and the like. Meanwhile, the disadvantage of water cooling is very obvious, and firstly, the danger possibly caused by pouring cold water on the brake pad suddenly is as follows: the brake pad may have tissue change in sudden temperature change, so that the decline of mechanical properties is caused; secondly, a water film is generated on the brake disc, so that calipers cannot effectively engage the disc like in the dry state during braking, and the parking distance is prolonged; again, an adequate water source cannot be ensured during driving.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides the cooling hub which can enable air on two axial sides of a wheel to flow in the driving process of a vehicle, so that air cooling is carried out on a brake pad, the working temperature of the brake pad is reduced, the brake performance is guaranteed, the driving safety is ensured, and the practicability is high.

The cooling hub comprises a hub body, wherein each spoke of the hub body is provided with a blade with an adjustable helical angle, namely the torsion angle of each blade is adjustable, so that the angle of each blade can be adjusted according to actual needs, and the wind resistance is reduced on the basis of ensuring the cooling effect on a brake pad.

Furthermore, the spoke is twisted into a fan blade structure, so that air is blown to the inner side of the wheel through the spoke in the advancing process of the wheel, and the cooling effect is improved.

Furthermore, the blades are arranged on the rear edge of the spoke, the rear edge of the spoke refers to the side edge of the spoke, back to the rotating direction, of the spoke when the vehicle moves forwards, and the installation structure is good in stability and attractive in appearance.

Further, the blade is installed in the spoke through rotating along the radial pivot of wheel hub body, the trailing edge of spoke is equipped with the limiting plate that extends to the blade inboard, the blade passes through bolt and limiting plate connection, every blade is connected with the limiting plate through two at least bolts, structural stability is better, it causes the blade to shift to avoid single bolt not hard up, can directly reequip on current vehicle, grooving and processing screw at current vehicle wheel hub's spoke trailing edge promptly, then the pivot of preassembling on with the blade is fixed at the inslot, then connect blade and screw with the bolt, can accomplish the repacking, therefore, the clothes hanger is strong in practicability, and the popularization and application of technology is facilitated.

Further, the bolt passes through the thread tightening on the limiting plate, be equipped with the connecting hole that supplies the bolt to pass on the blade, still the cover is equipped with the pressure spring on the bolt, the pressure spring supports between limiting plate and blade, and the aperture of connecting hole sets up rationally to guarantee that the rotatory in-process of bolt does not take place to interfere with the blade structure, combine the pressure spring can realize the effective location of blade, and convenient in the adjustment of blade angle.

Furthermore, the limiting plates and the blades are provided with sinking grooves corresponding to the ends of the pressure springs, so that the pressure springs can be reliably positioned, and a larger installation space is provided for the pressure springs.

The invention has the beneficial effects that: the cooling hub can drive air on two axial sides of the wheel to flow in the driving process of a vehicle, so that the brake pad is cooled by air cooling, the working temperature of the brake pad is reduced, the braking performance is guaranteed, the driving safety is ensured, the cooling hub can be directly refitted on the existing vehicle, the practicability is high, and the popularization and the application of the technology are facilitated.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the invention pertains.

As shown in fig. 1 and 2: the cooling hub of this embodiment, including hub body 1, install a helical angle adjustable blade 4 on every spoke 2 of hub body 1, the torsion angle of every blade 4 is adjustable promptly, consequently can adjust blade 4 angles according to actual need, reduces the windage on the basis of the cooling effect of assurance to the brake block.

In this embodiment, 2 spokes are twisted into a fan blade structure, so that the wheel moves forward and blows air to the inner side of the wheel through 2 spokes, and the cooling effect is improved.

In this embodiment, the blades 4 are installed on the rear edge of the spoke 2, and the rear edge of the spoke 2 refers to the side edge of the spoke 2, which faces away from the rotating direction when the vehicle moves forward, so that the installation structure is good in stability and attractive in appearance.

In this embodiment, blade 4 is installed in spoke 2 through rotating along 1 radial pivot 5 of wheel hub body, the trailing edge of spoke 2 is equipped with the limiting plate 6 that extends to 4 inboards of blade, blade 4 passes through bolt 3 and is connected with limiting plate 6, every blade 4 is connected with limiting plate 6 through two at least bolts 3, structural stability is better, avoid single bolt 3 not hard up to cause blade 4 to shift, can directly reequip on current vehicle, fluting and processing screw at current vehicle wheel hub's spoke trailing edge promptly, then fix the pivot of preassembleing on the blade in the inslot, then connect blade and screw with the bolt, can accomplish the repacking, therefore, the clothes hanger is strong in practicability, and the clothes hanger is favorable to popularization and application of technology.

In this embodiment, bolt 3 passes through the thread tightening on limiting plate 6, be equipped with the connecting hole that supplies bolt 3 to pass on the blade 4, it is equipped with pressure spring 7 still to overlap on the bolt 3, pressure spring 7 supports between limiting plate 6 and blade 4, and the aperture of connecting hole sets up rationally to guarantee that 3 rotatory in-process of bolt does not take place to interfere with blade 4 structure, combine pressure spring 7 can realize blade 4's effective location, and convenient in the adjustment of blade 4 angles.

In this embodiment, limiting plate 6 and blade 4 are gone up and are equipped with heavy groove corresponding to pressure spring 7 tip, can not only carry out reliable location to pressure spring 7, provide bigger installation space moreover for pressure spring 7.
