Description

Eccentricity correction device for bicycle wheel

The utility model relates to a kind of eccentric adjuster of cycle wheel, and particularly a kind of cyclist of making has the wheel eccentricities control apparatus of the sensation of riding.

Because the transformation of social pattern make the human lives present the busy phenomenon of a slice, so people more and more payes attention to various pastimes, to relax heartily, many people like outing, especially have the bicycle outing that motion is played concurrently, so that reach the purpose of loosening by driving motion.But Regular Bicycle, people often feel to ride not enough the stimulation, especially youngster, prefer riding, yet horse-riding is limited by the place, and expense is too high, the problem that also has a horsemanship training problem and overcome horse property, moreover safety also is a problem, so horse-riding, obviously is not to being fit to per capita that all are had a holiday.

The purpose of this utility model is the eccentric adjuster of a kind of cycle wheel of exploitation, makes the cyclist behind control stalk of operation, and bicycle wheels all can be made periodically eccentric motion, has the great-jump-forward pleasant sensation of riding; Control stalk is resetted, then still can ride as Regular Bicycle.

Another purpose of the present utility model provides a kind of cycle wheel eccentric adjuster, makes must not have superb equitation by ordinary consumer, must not defray enormous cost, and also can enjoy the temperament and interest of riding safely.

Cycle wheel eccentric adjuster described in the utility model is a wheel rim that replaces Regular Bicycle with inside and outside two wheel rims, connects with many spokes between the interior outer rim.The both sides, center of inner rim are separated by a distance to be installed with two blocks of parallel track plates, suitable position in the heart in two track plate outer ends and outer end and the wheel shaft, be welded with a slice locating plate respectively, the screw rod that outer end is provided with a gear passes the outer end locating plate, and the screwed pipe at inboard locating plate middle part, be placed in the recess hole of the collar one end on the wheel shaft axle skin and insert.The nut of on screw rod inserts an end of recess hole, burn-oning in advance, treat that screw rod inserts recess hole after, be screwed into a bolt from the recess hole side again, make when screw rod rotates, can drive wheel shaft axle skin and move up and down.

Respectively be provided with a pair of adjustment skewback in the front and rear fork inboard of vehicle frame in addition, described skewback just in time is positioned at the inner rim outside and the corresponding position of gear, aforementioned screw rod outer end, skewback is provided with the tooth bar that can slide up and down along a guide groove, and two pairs of tooth bars that the front and back car is stuck all link to each other with a control stalk of installing on the handlebar vertical tube with cable wire.The operation control stalk can make the up and down slippage of two pairs of tooth bars, is bevelled owing to adjust skewback, just can make tooth bar be in energy and aforementioned screw rod outer end gear mesh or can not position engaged.Under the last situation because wheel whenever turns around, gear and tooth bar only momently engagement once, and the eccentric adjustment of front and back wheel to be made as symmetry consistent, so have the sense of riding; Under one situation of back, can make Regular Bicycle and use.

The eccentric adjuster of the utility model institute readme cycle wheel, it is multi-functional to make that bicycle has, and both can make Regular Bicycle and use, can make front and back wheel make periodic consistent eccentric motion again, the order person of the riding sense of riding, the motion that is suitable for having a holiday is whiled away the time, both saved money, again safety.

Now, describe cycle wheel eccentric adjuster described in the utility model in detail in conjunction with all accompanying drawings.

Consult Fig. 1 to Fig. 3, wheel eccentricities control apparatus described in the utility model comprises structure improved wheel part and control part.In the wheel part, front and back wheel all changes into has outer rim (31) and inner rim (1), connects with many spokes (32) between the interior outer rim, is equipped with tire (3) on the outer rim (31).Both sides, inboard center at inner rim (1), suitably distance is welded with two parallel track plates (11) at interval, and be welded with a locating plate (18) in the outer end of two track plates (11), suitable position between locating plate (18) and center, be welded with another locating plate (17) again, locating plate (17) is all vertical with track plate (11) with (18).Central authorities in locating plate (17), be installed with a screwed pipe (16), central authorities then are provided with a through hole at locating plate (18), and suitable screw rod (2) of length runs through the through hole on the described locating plate (18) and is screwed into screwed pipe (16) on the locating plate (17).In addition thin position puts a collar (12) in the middle of wheel shaft axle skin (13), described axle skin and go up collar right position in the central authorities of described track plate (11).The collar (12) one ends protrude and are formed with a recess hole (15) downwards.After one end of aforementioned screw rod (2) passed screwed pipe (16), the what screw rod end suitable nut (22) of a size of burn-oning inserted then in the described recess hole (15), and is screwed into a bolt (14) in recess hole (15) one sides, to block described nut (22).Like this, when screw rod (2) when rotating up and down, the collar (12) is satisfied interlock with it, to reach the purpose of the eccentric rotation of front and back wheel.The rotation of screw rod (2) is then realized by the gear that is fixedly arranged on its outer end (21).

Cooperate Fig. 4 again, 5,6, control part once is described.The proper site inboard is gone up in back vent before cycle frame (33) and (34), is respectively equipped with a pair of adjustment skewback, and every pair of skewback is by (4), and (5) two skewbacks are formed.Now just figure (5) describes one of them skewback (4) in detail.The set collar (44) at this its rear portion of adjustment skewback (4) mat and be fixed in the inboard of car fork (33), adjust skewback (4) and have an inclined-plane (40), the centre offers a guide groove (42) among the described inclined-plane (40), to hold a set guide rail (43) in tooth bar (41) back with respective ramp, guide rail (43) can freely slide in guide groove (42) but can not deviate from.Multiplexing cable wire (6) is connected tooth bar (41) with control stalk (7) on being installed in handlebar vertical tube (62), operation control stalk (7) can make tooth bar (41) slippage up and down.Totally two pairs of aforementioned adjustment skewbacks, rear vehicle fork inboard before being satisfied with respectively sees that every couple in figure (4) comprises skewback (4) and (5), which is provided with tooth bar (41) and (51), mat cable wire (6) reaches (61) and is connected with control stalk respectively.

By bike the time, the person's of riding mat pedal crank (8) and drive sprocket (81), and the transmission of mat chain (82) makes the trailing wheel rotation.When the gear (21) of screw rod (2) end be positioned at can not and tooth bar (41), during (51) position engaged, use as Regular Bicycle.If operate control stalk (7) up or down, the different cable wires (6) that car is stuck before and after can straining respectively and (61), thereby make the tooth bar (41) of front-wheel or trailing wheel, (51) along adjusting skewback (4), (5) guide groove on the inclined-plane slides up and down, enter can with gear (21) position engaged.Regulate because front and back wheel be a symmetry, and gear (21) when wheel whenever turns around only momently and tooth bar (41), mesh (51), so make periodically off-center of wheel, makes the person of riding that the feel of riding is arranged then.
