Abstract
The utility model discloses the steering device of a tricycle. The utility model is composed of a steering wheel (1), a transmission shaft (8), a cylindrical gear (10), and a gear base (2); the steering wheel (1) is connected with the cylindrical gear (10) through the transmission shaft (8); one end of the gear base (2) is fixed with the upper clamping plate (5) of a front fork, and the other end of the gear base (2) is an arc inner gear (11). When the steering wheel (1) is rotated, the gear base (2) is driven by the engagement of the gears to rotate, and a front wheel (7) is turned by the rotations of the upper clamping plate (5) of the front fork, and a front fork (6). The utility model has the advantages of simple structure, flexible and easy operation, wear reduction for the front fork shaft of the front fork, etc.
Description
The utility model relates to a kind of steering apparatus of three-wheel vehicle, particularly the steering apparatus of three-wheel vehicle steering front wheel.
What three-wheel vehicle generally used at present is the steering control mechanism of the hand steered horizontal handle of shaking hands, it is to make by directly pulling handgrip that fork shaft rotates before the three-wheel vehicle, control turning to of three-wheel vehicle front-wheel, thereby the relatively heavier effort of steering, and bigger to the wearing and tearing of preceding fork bearing.
The purpose of this utility model provides relatively easy and flexible of a kind of steering, to the less three-wheel vehicle steering apparatus of front fork axle bearing wearing and tearing.
In order to achieve the above object, the technical solution adopted in the utility model is: stretch out a fixing all-in-one-piece toothholder with it on three-wheel vehicle front fork train wheel bridge, one end of toothholder is an arcuate inner gear, fork shaft is a fulcrum before the toothholder, driving front fork by the front fork train wheel bridge rotates, what be meshed with arcuate inner gear on the said toothholder is cylindrical wheel, and this cylindrical wheel is connected with bearing circle by transmission shaft, and transmission shaft relies on support to captive joint with frame assembly.When steering wheel rotation, drive cylindrical wheel and rotate, by the engagement between gear, make toothholder drive front fork and rotate, thereby steering front wheel is turned to.
Adopt this steering apparatus, owing to be by the gear meshing effect, handle turning to of front-wheel, thereby use easy and flexible, make the comfortable indefatigability of people, the compressing power that alleviates simultaneously preceding fork shaft has prolonged its service life.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing is the steering apparatus three-dimensional view of the utility model three-wheel vehicle.
In the three-wheel vehicle steering apparatus shown in the drawings, on folder 5 on the three-wheel vehicle front fork, useful bolt 4 fixes all-in-one-piece toothholder 2 with it.The other end of toothholder 2 is arcuate inner gears 11.Fork shaft 3 is a fulcrum before the toothholder 2, drives front fork 6 by front fork train wheel bridge 5 and rotates.What be meshed with arcuate inner gear 11 on the toothholder 2 is cylindrical wheel 10, and cylindrical wheel 10 is connected with bearing circle 1 by transmission shaft 8, and the bearing carrier ring 9 of transmission shaft 11 relies on supports 12 to be fixedly connected on frame assembly 13 and connects.When steering, steering wheel rotation 1 drives the rotation of cylindrical wheel 10 by transmission shaft 8.Because cylindrical wheel 10 and transmission shaft 8 fix motionless with frame assembly 13, cylindrical wheel 10 rotates the engagement with arcuate inner gear 11, fork shaft 3 rotates for fulcrum drives front fork 6 by front fork train wheel bridge 5 before making toothholder 2, thereby makes steering front wheel 7 rotation directions.
Claims (1)
1, a kind of steering apparatus of three-wheel vehicle, it is characterized in that: stretch out a fixing all-in-one-piece toothholder (2) with it at three-wheel vehicle front fork train wheel bridge (5), one end of toothholder is arcuate inner gear (11), fork shaft (3) is a fulcrum before the toothholder (2), drives front fork (6) by front fork train wheel bridge (5) and rotates.Cylindrical wheel (10) is meshed with arcuate inner gear (11) on the toothholder (2), and cylindrical wheel (10) is connected with bearing circle (1) by transmission shaft (8), and transmission shafts bearing sleeve (9) relies on support (12) to captive joint with frame assembly (13).
