Abstract

The utility model discloses a double function bicycle wheel which is suitable for various kinds of bicycles. The utility model can be installed on a general bicycle frame by only lengthening a front fork and a rear fork appropriately. The utility model can travel smoothly as a general bicycle wheel and can be changed into an eccentricity wheel with a definite eccentricity quantity in seconds through simple adjustment when needed. When the wheel center of one wheel or two wheels of the two-wheel bicycle is adjusted to be with a definite eccentricity quantity, the bicycle body and riders can travel upwardly and downwardly like the curve of cycloid when the bicycle is ridden to make the riders obtain especial body-building and amusement efficiency. The utility model is suitable for bicycles of children of various ages.

Description

Dual-functional wheel of cycle

The utility model relates to a kind of improved cycle wheel, particularly a kind of two function cycle wheels that can change the vehicle ' function, and it is applicable on various children, teenager's two-wheeled, the tricycle.

Existing various cycle wheel mainly is made up of tire, wheel rim, spoke, bearing cartridge etc., bearing cartridge is tightened in the wheel rim center regularly with guiding principle silk spoke, the wheel of the various large and small bicycles of selling all belongs to this kind structure in the market, and its function is to carry steady rolling of vehicle body to travel.Existing ordinary bicycle as walking-replacing tool its intrinsic light labour-saving characteristics of travelling are arranged but for children, teenager with bicycle, only have above-mentioned functions and just seem to some extent not enough.

Task of the present utility model be a kind of improved cycle wheel will be provided, it can roll reposefully as common wheel and travel, also can make wheel be transformed into the eccentric wheel that core wheel has certain offset in tens of seconds through easy the adjusting when needed.The bicycle of this kind wheel is housed, axletree, vehicle body rise and fall to jump by the curve of approximate cycloid and move ahead, become a kind of body-building vehicle of travelling suddenly after its wheel is adjusted to eccentric wheel, when travelling, its height that rises and falls can be regulated arbitrarily in specialized range.

Task of the present utility model is finished as follows: have concentric wheel hub circle, two circles to be linked by many spokes in the wheel rim of wheel, article two, be used to center line both sides in the logical circle with the wide tabular main wheel spoke symmetrical parallel ground of wheel hub circle, its four narrow limits form four tracks, have rectangular flange and be furnished with rectangular platen the core wheel regulating block, be stuck in the middle of four tracks on tabular main wheel spoke limit with two pairs of corresponding shallow peace grooves.One steering wheel shape nut screws on one section screw thread of rectangular platen outer end bearing cartridge, when steering wheel shape nut is in releasing orientation, can hand push core wheel regulating block at four track superior displacements, the bearing cartridge of core wheel regulating block middle part establish an elasticity sphere steady arm, with its can move offset be divided into a plurality of five equilibrium pre-determined bit in the hole, garden, location of tabular main wheel spoke, again screw rudder shape nut, the rectangular flange on rectangular platen and the core wheel regulating block is pressed on four tracks, make the core wheel regulating block become an integral body with wheel hub wheel rim sports association.

The core wheel regulating block be divided into front-wheel with and trailing wheel with two kinds, its difference is that the standard belt brake wheel that has only on bearing cartridge that front-wheel is used is located, trailing wheel use then except that standard belt brake wheel location is arranged, adorn the peace position of standard flywheel in addition, when being used on children's kiddie car, then can not make driving wheel.

When bicycle adopts two function wheels of following example structure, its vehicle frame part only needs that size with forward and backward fork correspondingly cooperates with wheel, all the other structures are constant, the cost of car load is a little more than ordinary bicycle.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the front elevation of a kind of concrete structure of the utility model;

Fig. 2 is the semisectional view of Fig. 1 along center line;

Fig. 3 is the cutaway view of Fig. 1 along the A-A line;

Fig. 4 is the D-D profile of Fig. 1;

Fig. 5 partly cuts open lateral plan with what two pairs of bolts replaced steering wheel shape nut structures;

Fig. 6 is the geometric locus of the utility model wheel approximate cycloid that its accentric axle marks in the space when being adjusted to eccentric wheel and travelling.

Take turns on the wheel rim (3) of circle body (2) at wheel hub with reference to Fig. 1,2,3 one ordinary bicycle tires (1) hoop, here, wheel hub wheel circle body (2) is to make with aluminum alloy or engineering plastics or sheet steel, it is made up of wheel rim (3), many little spokes (4), wheel hub circle (5), two tabular main wheel spokes (6) and several little oblique spokes (18).Four parallel edges of two tabular main wheel spokes (6) form four tracks (7), shallow peace pair of parallel and that the cross section overlaps with track (7) position groove (10) is respectively arranged, so that two are embraced and are stuck on four tracks (7) on the rectangular flange (15) on the core wheel regulating block (8) and the medial surface of rectangular platen (9).Core wheel regulating block (8) can be gone up slippage or fixing at four tracks (7) after assembling.Its slippage or fixedly be to screw unclamping or fastening realization of steering wheel shape nut (11) on core wheel regulating block (8) one section screw thread of bearing cartridge (12) by one, steering wheel shape nut (11) is a pair of male and female conical surface (19) that coincides with the face that rectangular platen (9) is leaned on mutually.

The core wheel regulating block that front-wheel is used only has the screw thread peace position (23) of one section dress standard belt brake wheel at its bearing cartridge one end, and dress brake wheel (20).What trailing wheel was used then adds one section screw thread peace position (21) of adorning the standard flywheel at the other end, and adorns a flywheel (22).Between the inner end surface of front and rear wheel with the outer face of the steering wheel shape nut (11) on the core wheel regulating block (8) and brake wheel (20) one section gap of moving about is arranged all.

With reference to Fig. 5 core wheel regulating block (8) fastening on four tracks (7), except adopting the mode that steering wheel shape nut (11) compresses, can also adopt the mode that respectively rectangular flange (15) and rectangular platen (9) is compressed with two pairs of bolts (16) as shown in Figure 5.

With reference to Fig. 2,4 at the bearing cartridge of core wheel regulating block (8) middle part with the mutually close either side of tabular main wheel spoke (6), establish an elasticity sphere steady arm (13), can make the core wheel regulating block divide some five equilibrium pre-determined bit on tabular main wheel spoke (6) center line in the hole, corresponding garden (14).

When steering wheel shape nut (11) or bolt (16) when being in releasing orientation, core wheel regulating block (8) can be shifted with hand push, its amount of movement can from 0 be displaced to required offset pre-determined bit to maximum, core wheel regulating block after, screw steering wheel shape nut (11) or bolt (16) again, rectangular platen (9) and rectangular flange (15) are compressed, are fixed on four tracks (7), make core wheel regulating block (8) become as a whole with wheel hub wheel circle body (2).

With reference to Fig. 6, when core wheel offset that regulating block is transferred is R, then the geometric locus β of an approximate cycloid is marked in its accentric axle center behind the wheel rolling in the space, this beta curve nadir h to the diff-H of vertex H be 2R, the offset R value of transferring big more, then the h point diff-H of ordering to H is big more, promptly be bearing in vehicle body on the axle during wheel rolling and rise and fall to jump and rise highly more.
