Abstract
The utility model relates to a novel heat radiation hub, which comprises a conical cylindrical body (3), wherein a bearing chamber (2) and a sealing chamber (1) are arranged in the axial direction of the conical cylindrical body (3), and a radially protruding flange (5) is arranged on the outer circumferential surface of the conical cylindrical body (3). The novel heat radiation hub is characterized in that a set of heat radiation holes (6) are formed in the circumferential direction of the flange (5). The novel heat radiation hub has the following benefits: the heat radiation holes result in convection of air on the two sides of the flange, achieving the effect of heat radiation; and the heat in the inner chamber of a braking system is radiated in time, so as to avoid the conduction of the heat to the interiors of the bearing chamber and the sealing chamber, which prolongs the service life of a bearing and a sealing mechanism, greatly reduces the vehicle transportation cost, and greatly improves the safety of vehicle traveling.
Description
Technical field
The utility model relates to the car chassis parts, is widely used in a kind of heat sinking wheel hub of medium and heavy automobile, engineering truck and extraordinary special-use vehicle.
Background technology
Vehicle hub is land (removing tracks such as train) transport vehicle vehicle bridge or the requisite parts of axle unit; Be to rotate in the vehicle bridge to carry the foundation support parts; The bearing chamber of wheel hub connects with axletree through bearing, and flange connects with rim for automobile wheel and brake wheel through wheel bolt, on one side a rotation supporting role; Play brake action on one side, sealed chamber plays the sealing and dustproof effect; Reinforced rib strengthens the strength and stiffness of this machine, and existing product technology heat dispersion is undesirable, often sees on the highway; The phenomenon of catching fire the traveling automobile tire takes place, and major cause is the vehicle that goes in high-speed overload vehicle or mountain area, because frequent braking; Fricative heat can not in time leave in the vehicle bridge and between joining brake wheel of wheel hub and the drg, makes the temperature build-up of brake wheel, directly causes " rubescent "; Arrive the burning-point of tire, tire is caught fire, produce great potential safety hazard.
The utility model content
The purpose of the utility model is to have the defective that wheel hub can not in time leave at fricative heat now in order to solve, and a kind of heat sinking wheel hub is provided.
The utility model solves the technical scheme that its technical matters adopted:
A kind of heat sinking wheel hub; Comprise a tapered cylinder; Tapered cylinder axially on have bearing chamber, sealed chamber, on the tapered cylinder outer peripheral face, have radially outstanding flange, it is characterized in that: at flange along upwards being provided with one group of louvre week.
On the basis of above-mentioned main technical schemes, can increase following further perfect technical scheme:
Described louvre is positioned at the flange root near tapered cylinder.
The axis of described louvre and the axis of tapered cylinder have an angle.
Described angle is an angle greater than positive 90 degree.
The beneficial effect louvre of the utility model makes the circulating air of flange both sides, reaches thermolysis; Because the heat of brake system inner chamber is in time discharged, and also avoids its heat to be transmitted in bearing chamber and the sealed chamber, has prolonged the service life of bearing and sealing mechanism, greatly reduces vehicle transportation cost, has greatly improved the safety of vehicle '.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Description of drawings:
Fig. 1 is the front view of the utility model.
The specific embodiment
As shown in Figure 1, a kind of heat sinking wheel hub of the utility model comprises tapered cylinder 3 structures, and tapered cylinder 3 inner chambers are provided with two bearing chambers 2; Two is respectively sealed chamber 1, and generally through cast form, tapered cylinder 3 outer peripheral faces have radially outstanding flange 5 on the middle part; Be provided with reinforced rib 4 between flange 5 both sides and the cylinder, flange 5 is provided with wheel bolt fixed orifice 8, and flange 5 two sides are respectively equipped with wheel rim positioning spigot 9 and brake wheel locating surface 7; Along upwards being provided with one group of louvre 6 week, the quantity of louvre 6 can and be provided with five according to the big or small of wheel hub under the condition that does not influence wheel hub intensity at flange 5, six, eight or more louvre 6; Louvre 6 makes the circulating air of flange 5 both sides, reaches thermolysis, and one group of louvre 6 can be around the axis rectangular distribution of tapered cylinder 3; Can make the heat radiation of wheel hub more even like this, also can louvre be set according to the concentrated area fitfull that friction generates heat that receives of wheel hub, the axis of the axis of louvre 6 and tapered cylinder 3 has an angle greater than positive 90 degree; This louvre 6 is convenient to wheel hub and is received after friction generates heat, spreads circulation laterally through this louvre 6, and because louvre 6 is positioned at flange 5 roots near tapered cylinder; Can prevent that wheel hub from receiving accumulates in root and can't discharge after friction generates heat, vehicle high-speed overload or in the mountain area when uneven road surface goes, because frequent braking; Produce very big heat; Temperature build-up in the brake system, pressure are also along with rising, greater than the outer atmospheric pressure of brake system inner chamber; So the hot air of brake system inner chamber is discharged through the louvre on the flange 56; Do not cause the particularly temperature build-up of brake wheel of brake system, avoid tire to catch fire, prolong the service life of wheel rim, tire.
Claims (4)
