Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further detailed.
As shown in Figure 1 and Figure 2, the dynamic flywheel of freedom of a kind of automotive hub that the utility model preferred embodiment provides, it comprises: the mandrel 7 of an aluminum alloy, the upper end of this mandrel 7 is shaft part, lower end to be installed be and the location shaft part of automotive hub centre hole adaptation, the stage casing of this mandrel is provided with annulus 10, and on annulus, annular is evenly equipped with five mounting hole 11(that connect automotive hub for mounting screw 6 incorporated by reference to Fig. 3, Fig. 4).Shown in Fig. 5, Fig. 6, the flywheel 5 of one aluminum alloy, in the mesopore of this flywheel, be provided with a bearing 4, flywheel is arranged on the installation shaft part of mandrel 7 by this bearing, and flywheel 5 is connected with mandrel 7 with pressure ring 3 by a mandrel screw 2, then by bearing cap shim 1 in the mesopore that is threadedly connected to flywheel by its cylindrical.In the present embodiment, on flywheel 5, annular is arranged with kinetic balance hole 12, and the circle diameter that this kinetic balance orifice ring shape arranges equates with the circle diameter of the 11 annular settings of the mounting hole on mandrel annulus, and the diameter in kinetic balance hole 12 is greater than the diameter of mounting hole 11.The surface (lower surface) of the mounting hole 11 of the corresponding mandrel 7 of flywheel 5 is provided with the groove 13 that can hold 6 of mounting screws of annular.Mounting screw 6 is fixedly connected on mandrel 7 on the termination of center tightening screw 9 of former automotive hub by an isolation pad 8.The spoke of flywheel 5 by seven radially, spoke 14 spaced apart forms, the relative main shaft vertical direction of each spoke side has the suitable angle of inclination between 15 ~ 30 °, to keep flywheel when rotation to have the flow of cold air that drives former wheel hub space, be unlikely to again to produce in walking at a high speed and excessively strengthen bearing load from axle wind-force.And seven kinetic balance holes 12 are located in the flywheel main body between adjacent spoke.As required, the spoke of flywheel 5 can be designed to various difformity and the different spoke quantity with proper strength, such as, spoke is set to five width or 12 width quantity etc.The outside face of flywheel 5 can also be provided with color fluorescence decorative pattern layer (not shown).
Refer to Fig. 1, Fig. 2, when installation, can be first flywheel 5 and bearing and mandrel 7 be connected into a flywheel assembly, pass the kinetic balance hole 12 of flywheel 5 through mounting hole 11 and the isolation pad 8 of mandrel 7 with mounting screw 6 again, flywheel assembly is fixedly connected with the end of the tightening screw 9 at former automotive hub center.Now, mandrel 7 is fixedly connected on automotive hub lateral surface, but flywheel 5 is parallel to automotive hub lateral surface and can freely rotates relative to automotive hub is positive and negative by bearing 4.According to different situations, the number in kinetic balance hole 12 is not necessarily identical with mounting hole 11, but the circle diameter of both annular spread is identical.Like this, as long as flywheel is rotated relative to mandrel 7, so that mounting screw 6 just can be inserted in kinetic balance hole 12 in the time that mounting hole 11 is coaxial.
Because the utility model is installed on the center fastening screw of the original aluminium alloy wheel hub of automobile of high-speed operation,
In order to ensure impact strength and structural strength, the utility model adopts fine aluminum alloy sheets material CNC machine-shaping, and carries out ball blast oxidation equal stress and surperficial cure process.The metal at key construction position connects thickness and is not less than 5mm, center operating shaft bearing structure adopts the high-quality loading bearing that is not less than 150 times of rotary hub body weight, while having ensured that the utility model freely rotates at a high speed, high pulling torque when the large load impact of generation and sharply turning are beated in the sudden change that also can bear original wheel hub is loaded.Do not affecting under the precondition that is fastened securely intensity of the original wheel hub screw of automobile, the utility model passes through D6mm high-strength anti-theft fastened by screw on the tightening screw termination of former automotive hub, to have ensured centering and the kinetic balance of the utility model and former automotive hub, the bad and appearance of the jumping tire potential safety hazard that causes of the kinetic balance that effectively prevented wheel hub fabricate block.
Because the utility model entirety is anchored on automotive hub outside above, increase on the one hand the weight of wheel of the bus, make the center of gravity of tire reduce, thereby increased the ground ability of grabbing of motor tire, improve the driving safety of automobile; Owing to following automobile sport, the wind-force that the utility model High Rotation Speed produces is accelerated the radiating rate of brake disc system on the other hand, so that has improved braking quality.Installation of the present utility model is very simple, does not need to change the original aluminium alloy wheel hub of automobile.After installation, the utility model can very freely rotate back and forth on original automotive hub, by taking center shaft as basis, when design different spoke architecture or wheel hub color or decorative pattern etc. on flywheel, can realize the dynamic free motion wheel hub of the various feature individual characteies of automobile.
Automobile of the present utility model is installed and starts when walking starting, do not turn because inertia the utility model is substantially static, make whole automobile seem to have like wheel then skid off the same visual effect on ground.Then, under the rotary wind power effect producing in automotive hub rotation, the utility model starts to follow High Rotation Speed to the rotating speed that approaches actual tire.In the time of parking of automobile, because inertia the utility model also keeps the free state of High Rotation Speed, whole automobile is seemed to have like automobile by unsettled and wheel also at the dynamic visual effect of original place high speed rotating, can guide the cold air of wheel hub periphery constantly through brake disc system at the flywheel that continues rotation simultaneously, accelerate brake disc cooling, until the utility model stops operating gradually because of air resistance and self bearing resistance factor.The feature of above novelty has brought very joyful cultural life to the car owner of hobby fashion and characteristics of personality.
Prototype test product starts trial assembly on automobile and carries out safety on probation on April 27th, 2012, speedometer for automobile was recorded as 79785 kilometers at that time, and trail run finishes mileage meter and is recorded as 123782 kilometers, amounts to test miles and is about 43997 kilometers.Experience during this time the repeatedly high speed mileage of the round approximately 15000 kilometers of 120km/h in Shenzhen to Baiyun District, Guangzhou; All the other are the comprehensive road traveling in urban district, suburb etc. substantially; For completing as early as possible security test, run more arduously.Live through during this time sharply turning, burning hot weather road surface, rotten road, stone road, rainwater ponding road, lanyard, side road serratd edge, scratched etc. comparatively severe test condition by other cars, after dissembling inspection, find, this test article is except surface scratching the darker cut in several places of appearance because of automobile and clump, mechanical rotation structure is still strong firm, without distortion and crackle, run at high speed middle tire still without obviously beating and the appearance of abnormal sound situation, and kinetic balance is not significant change still.So far, prove that this product has conformability from designing to the safety Test Application, has reached the requirement of the Secure Application of formal product.
