Description
Invention field
The present invention relates to the connecting device of bicycle, particularly in order to be controlled at dynamic transversely unstable exercise wheel assembly set or secondary side wheel assembly set on the uneven ground.
Background of invention
The insider knows that technical is that the control bicycle is dynamically laterally unstable, can add a pair of detachable auxiliary side wheel at bicycle rear shaft.Really, bicycle is a kind of vehicle that improves its dynamic stability by increasing the speed of a motor vehicle; During low speed, be difficult to keep lateral stability, especially to the child of unskilled operation bicycle or other people.When just meeting the foot-operated child of primary learning and the man-hour of shakiness by bike the time, just be sought after this auxiliary side wheel.
The problem that existing many auxiliary side wheels exist is with comprising that the device of the device that is rigidly connected is contained in them on the standard bicycle.This device that is rigidly connected is imperfect, because ground-surface injustice tends to cause that a side wheel compares the fugitiveness that relative another side wheel raises and in ground the bicycle generation should not be had.On the other hand, rear wheel can raise and the person of riding can temporarily lose propulsive force than ground.In addition, when bicycle and cyclist turned, the stability of vehicle can be damaged once more, because the device that is rigidly connected of side wheel is arranged, bicycle can not tilt.
Some patent is provided with suspension gear and has solved this problem between bicycle and auxiliary wheel.
The US Patent 5,942,354 that licensed to RAINEY in 1996 discloses the exercise wheel that is contained in a disc spring end, and this disc spring is contained in each side of rear wheel wheel shaft.Mutual being aligned of disc spring axis and biased downward, and parallel with hind axle, because disc spring can move up, the exercise wheel can be pulled back by the antagonistic spring effect.The shortcoming of the disclosed device of RAINEY is because of friction that uneven ground causes can make one to take turns to be drawn to resist backward and move forward, and bicycle is spinned.

Embodiment describes in detail
Shown in Fig. 1 and 2 is a standard bicycle 10, and it comprises rigid-frame 11, a trailing wheel 12 by axle 14 in the ground G upper support.
Fig. 3 and 4 shows that each side wheel connecting device 18 has elongated last inverted U end 20, one intermediate conveyor screw springs 22 and auxiliary wheel axle terminal part 24 once; The screw shaft of coil spring 22 is also laterally stretched out with respect to every pin 20 and 24 of spring installation 18.As shown in Figure 4, all parts 20,22,24 are almost in the same plane in its end elevation, but form the L type in the planar view (Fig. 3) under natural no-bias state.So coil spring 22 can make pin 20 and 24 shift near mutually and remove.Fig. 3 shows that coil spring 22 is loosening or wheel connecting device 18 during the no-bias state, and wherein pin 20 and 24 roughly forms the right angle each other, better is 95 °.When the relaxation state of Fig. 3, it is close that coil spring 22 can make pin 20 and 24 move mutually forcibly, or pin 20 and 24 is moved away from, but in a single day the positive bias that is added on pin 20 and/or 24 unclamp, and this spring will make pin 20 and 24 return back to 95 ° of angle states shown in Figure 3.Angular range between the pin 20 and 24 at 85 ° to 100 ° better.Best, axle portion 24 is in coil spring 22 fronts, and is crooked backward to prevent axle 24.
Side wheel connecting device 18 usefulness one are converted into the single structural poles of required form and make.In fact, U type end 20 and auxiliary wheel axle 24 form the two ends of coil spring 22, so side wheel connecting device 18 is easy to because of it is simple in structure constitute and installing.
The inverted U portion 20 of spring connector 18 is provided in a side of the side of bicycle quick 12, and almost parallel with it,, the threaded terminal part 14a of the car of hind axle 14 laterally passes outwards through the plane (see figure 1) of U type portion 20 so freely being stuck between two side legs 20a, the 20b of U type portion 20.
Carriage 26 preferably has the section that roughly is the C type, and contains the batter 20a that elongated interior slot part is used for engaging in circumferential part U type portion 20, and 20b is so that clip U type portion 20 between the parallel shelf structure 28 of carriage 26 and car owner's frame 11.So side wheel connecting device 18 is removably mounted on the bicycle 10.Like this, loosen nut 27, then between carriage 26 and frame 28 slip side wheel connecting portion 20 with regard to the height of scalable side wheel connecting device 18 with respect to trailing wheel 12.After finding required relevant position, refill and tightening nuts 27.
Each side wheel 16 rotatably freely is installed in respective mandrels 24 near its place, outer end, and the suitable arm of force of tool is long, shown in Fig. 1～2, two nuts that are spaced laterally apart 23 and 25 removably mesh axle 24, form propeller boss 16a engaging that a gap makes wheel 16 betwixt wherein and can rotate freely.The gap that detouchable is installed between the nut 23 and 25 should be enough little, to prevent taking turns 16 by its running face part inclination unexpectedly perpendicular to axle 24.Distance is longer between side wheel 16 and the coil spring 22, will cause that to use torsion just longer in the arm of force of spring 22, this will make side wheel 16 upwards at an easy rate because impose on the force rate of axle 24 near outer ends impose on the moment of torsion that the moment of torsion of axle 24 near coil springs 22 will produce in coil spring 22 will be greatly.So better be the end that side wheel is placed nearly axle 24, have than the necessary of multi-turn or select for use the big material of intrinsic elasticity to constitute necessity of wheel connecting device 18 to eliminate coil spring 22.
During use, set relative trailing wheel 12 connecting device 18 height preferably as shown in Figure 1, make trailing wheel 12 higher slightly than ground, at this moment do not have the cyclist on bicycle 10.So the contact of side wheel 16 1 direct sum ground G applies continuous downward pressure because of bicycle weight causes coil spring 22 on side wheel 16 under most of occasion.When the cyclist rides on the bicycle 10, its body weight is added on the bicycle weight, coil spring 22 can distortion make trailing wheel 12 kiss the earth G.Like this, the moment of torsion in the coil spring 22 can make two spring pins 24 and 28 adjacent to each other, by 95 ° to 90 °, side wheel 16 is made it to be permanently connected to ground G with suitable downward pressure, and trailing wheel 12 also can be kept with ground G and contacts and propelled bicycles 10.
If the ground G injustice, side wheel 16 can move up or down and compensate ground-surface injustice, and total three trailing wheels, 12,16,16 kiss the earths that keep of the effect of cyclist's body weight and coil spring 22.
From Fig. 5 and 6 as can be seen, even when the low speed of a motor vehicle or quiescence, how the present invention improves the lateral stability and the ground index power of car, because no matter how uneven ground is, always back wheels of vehicle keeps and ground engagement reliably.And the play of the circle of auxiliary wheel is sizable because of there not being second connecting piece---as prior art patent of being discussed in " background of invention "---between auxiliary wheel and the main axle.Really, when the terrain slope degree is big, can hinders auxiliary wheel 16 without any thing and around the spiral part 22 that connects spring, be moved upward to one near the position of main axle 14 and almost perpendicular to the plane at main wheel 12 places.The adjusting of wide region is the advantage of auxiliary wheel 16 just.
Figure 7 shows that the second embodiment of the present invention, wherein the wheel hub 16a of side wheel 16 is located on the sleeve pipe 30 pivotally, and sleeve pipe 30 is slidably regulated (as shown by arrows) along the length direction of side wheel axle 24.Sleeve pipe 30 can be fixed on a special axial location along axle by a default screw 32, and screw 32 is inserted on the sleeve pipe 30 with it in the corresponding screw 34 of the amplification terminal part 30a of one, one concave cover 36 is positioned on the outer end of axle 24, preventing accidental disconnected the wound, and preventing side wheel 16 axle 24 that slips away when screw 32 is not tightened in regulating side wheel 16 or using.
Having the purpose of adjustable positions of the side wheel 16 of default screw 32, is to set required arm of force length between side wheel 16 and the coil spring 22.This adjustable force arm lengths is favourable, uses the bicycle with side wheel 16 because of making the different cyclist of body weight like this.Necessarily enough make keep in touch ground and giving and trailing wheel 12 effective wagon wheel index power of trailing wheel 12 when really, cyclist's body weight is added in bicycle.The light cyclist of body weight just executes the moment of torsion of wanting to coil spring 22 than the longer arm of force length of the needs of heavyweight vehicle, makes trailing wheel 12 kiss the earth G.Be fit to different cyclists with regard to the auxiliary side wheel 16 of scalable like this and obtain side wheel 16 maximal efficiencies.Apprehensiblely be, on axle 24, can do scale graduation and represent cyclist's body weight, so just find out the position of wanting of side wheel 16 easily.
Such auxiliary wheel assembly set can increase cyclist's safety, makes him feel more confident and faster association running operation bicycle how.
Attaching parts 20,22,24 " (7mm), Young's modulus is that the rod iron of 207GPa makes with diameter 0.281 in preferred embodiment.Steel is OTMB steel and scribble heat-set ink preferably.Axle minister's degree is from vertical component effect 5 " (12.7cm); And the disc spring internal diameter is 1.75 " (4.45cm).These parts can be made of any suitable elastic material, make as forged steel rod or resilient solid semi-hard plastic bar.The tyre 16C of auxiliary side wheel 16 can make with plastic cement or elasticity neoprene, and auxiliary side wheel wheel hub 16a and spoke 16b should make as duroplasts with the rigid material of light weight.
In the auxiliary wheel connecting device of the Fig. 5 that is noted that in prior art, need periodic adjustment tight pulley connecting device A in the upright position of the nut N of back wheels of vehicle major axis X.Reason is that institute fixes time at interval, as every month twice, needs to increase the height of auxiliary wheel W, so that the lateral instability of car when making layman cyclist feel low speed gradually, and keep on the go safety and traveling comfort.
On the contrary, in the present invention of Fig. 6, the continuous adjusting of the height of auxiliary wheel 16 is carried out automatically according to condition of road surface, so continuously height adjustment obviously not only for security reason but also for learning objective all favourable.
