Abstract
The invention relates to a double-wheel turning mechanism which consists of rectangular slide blocks, a double-front-wheel rotary shaft, a front form shaft sleeve, swing rods, a housing, springs, a slide block line and a fixed pulley. The double-front-wheel turning mechanism is provided with two rectangular slide blocks capable moving mutually and parallelly, each rectangular slide block is connected with the corresponding swing rod through a hinge, the swing rods are inserted into rotary shaft holes formed in two front wheels, the swing rods can freely extend in the rotary shaft holes formed in two front wheels, a front wheel shaft is connected with a front form shaft sleeve, the front form shaft sleeve can rotate around the front form shaft, the swing rods can vertically swing around the hinges in the slide blocks through long grooves formed in the housings of the slide blocks to drive the double-front-wheel rotary shaft to swing around the front fork shaft, the bottoms of the slide blocks are connected with the bottom of the housing through springs and bypass the fixed pulley under the housing through the slide block connecting line to be connected with another slide block, and the upper ends of the two slide blocks are connected with a turning line. The problem that a double-front-wheel bicycle body inclines during turning and accordingly the wheel on one side is away from the ground is solved.
Description
Technical field:
Patent of the present invention relates to a kind of turning of bicycle mechanism, belongs to bicycle structure design field.
Background technology:
The turning technology of current bicycle is very single, is only limited to single nose wheel steering mechanism.The bicycle being designed with double front wheel has better stability of equilibrium than single front wheel bicycle when travelling at a slow speed.And current double front wheel turning technology is at automobile technical field comparative maturity, because this technology can not realize the body inclination of Double-fronwheel cycle when turning, therefore cannot be applied on Double-fronwheel cycle.A kind of Double-fronwheel cycle body inclination when turning that can solve causes the turning mechanism of single wheel disengaging ground problem to seem particularly important for the bike tech of double front wheel.
Summary of the invention:
Single wheel is caused to depart from the problem on ground in order to solve Double-fronwheel cycle body inclination when turning, the technical solution adopted in the present invention is: a kind of two-wheel turning mechanism, it is characterized in that by rectangular shaped slider, double front wheel rotating shaft, front fork axle sleeve, swing arm, shell, spring, slide block line and fixed pulley composition, this double front wheel turning mechanism profile is cuboid, be arranged in the middle of double front wheel rotating shaft, vertical with front fork, front fork is triadius type, turning mechanism inside is provided with the rectangular shaped slider of two motions that can be parallel to each other, each rectangular shaped slider is connected with swing arm by hinge, each swing arm injects in the rotating shaft axis hole of two front-wheels respectively, swing arm is retractable in the rotating shaft axis hole of front-wheel, front wheel spindle is connected with front fork axle sleeve again, front fork axle sleeve can rotate around front fork shaft, swing arm can be swung up and down by the hinge of the elongated slot of slide block shell in slide block, the rotating shaft of front-wheel is driven to swing around front fork shaft, slider bottom is connected with outer casing bottom spring, and be connected with another slide block by the fixed pulley that slide block connection lead is walked around below shell, two upper end of slide block connect turning guide marking.During turning, grab and close driver upper turn control, pull turning guide marking, with movable slider in respective slideway to doing the slip that sense of displacement is contrary, size is identical, thus drive the fork shaft swing before separately of two fronts wheel spindle, wheel both can left-right rotation, the kiss the earth while that the swing of fork shaft enabling double front wheel when turning before separately by two front axles again.
The beneficial effect of patent of the present invention be realize double front wheel both can left-right rotation, the kiss the earth while that the swing of fork shaft enabling double front wheel when turning before separately by two front axles again.The bicycle of double front wheel solves bicycle when travelling at a slow speed and has the problem of better stability of equilibrium, and the present invention then solves Double-fronwheel cycle body inclination when turning and causes single wheel to depart from ground problem.
Accompanying drawing illustrates:
Fig. 1 is the device schematic diagram of patent of the present invention
Detailed description of the invention:
Below in conjunction with accompanying drawing, patent of the present invention is further described.
In Fig. 1, grab conjunction driver upper turn control is pulled turning guide marking (8) during turning, rectangular shaped slider (5) meeting upward movement, rectangular shaped slider (7) then can move downward, thus realizes turning.At the end of turning, unclamp turning guide marking (8), spring (6) drives rectangular shaped slider (5), (7) reset, and double front wheel goes back to the state of moving forward.
