Abstract
The utility model discloses a steering mechanism for an independent floating front fork of a double-rider tricycle, which comprises a steering wheel, a steering wheel connecting shaft, a steering wheel support, an external cylindrical gear, an annular plate, a connecting rod and arms of force. The upper end of the steering wheel connecting shaft is connected with the steering wheel, the lower end of the steering wheel connecting shaft is connected with the external cylindrical gear via splines, and the middle section of the steering wheel connecting shaft is hinged to the upper end of the steering wheel support through a bearing. One end of the external cylindrical gear is provided with internal teeth meshing with the external cylindrical gear, the other end of the external cylindrical gear is hinged with the connecting rod, and the center of the external cylindrical gear is hinged to the lower end of the steering wheel support. Two ends of the connecting rod are respectively hinged to one ends of the arms of force. The steering mechanism is operated through the steering wheel and accordingly is convenient and comfortable in operation. The steering mechanism utilizing the external cylindrical gear and the annular plate to coordinate with the connecting rod and the arms of force is simple in structure and reliable in performance, and output torque can be adjusted conveniently so as to adapt to different designs of the load capacity lower than or equal to 1.8T. In addition, the steering mechanism is a special design for the existing independent floating front fork of the double-rider tricycle, can be mounted on the independent floating front fork of the double-rider tricycle conveniently and has no requirements for changing the original structure.
Description
Technical field
The utility model relates to the vehicle component technical field, is specifically related to the independently unsteady front fork steering hardware of a kind of pair of three-wheel vehicle.
Background technology
Traditional three-wheel vehicle is because of vehicle-mounted great being used widely of its cheap relative proper motion.But along with the development of society, more and more to the needs handling load, present three-wheel is can not satisfy the cargo-carrying needs.But four-wheeled, particularly automobile, complex structure, with high costs.So the modified version of existing three-wheel vehicle occurred: two three-wheel vehicles; Promptly on the architecture basics of three-wheel vehicle, increased a same front-wheel; Have simple in structure, the cheap advantage of traditional three-wheel vehicle, have four-wheeled to operate steadily, brake reliably, the strong point that load-carrying is big again.
But, above structure has also been brought a difficult problem, because be based on the improvement that three-wheel vehicle is done, its conventional steering mechanism turns to function at heavy with having more can not accomplish under the situation of a front-wheel.
Summary of the invention
The utility model goal of the invention provides the independently unsteady front fork steering hardware of a kind of pair of three-wheel vehicle, to solve the existing pair of existing above problem of three-wheel vehicle.
For reaching the foregoing invention purpose; The technical scheme that the utility model adopted is: provide a kind of pair of three-wheel vehicle independently unsteady front fork steering hardware, it is characterized in that: comprise steering handwheel, steering handwheel adapter shaft, steering handwheel support, outer cylinder gear, internal tooth ring plate, connecting rod and arm bar; Said steering handwheel adapter shaft upper end is connected with steering handwheel, and the lower end spline connects outer cylinder gear, and the stage casing is hinged through bearing and said steering handwheel support upper end; Said outer cylinder gear one end is provided with and outer cylinder gear ingear internal tooth, and the other end and said rod hinge connection, outer cylinder gear central portion are hinged to steering handwheel support lower end; Said connecting rod two ends are hinged to an end of said arm bar respectively.
According to the independently unsteady front fork steering hardware of two three-wheel vehicles that the utility model provided, it is characterized in that: said steering handwheel support is fixedly connected on the crossbeam that is used to connect two front forks; The other end of said arm bar is captiveed joint with the preceding fork shaft of two front forks.
In sum, this steering hardware adopts the steering handwheel operation, meets four-wheeled is got operating habit, and simple operation is comfortable; Adopt outer cylinder gear and internal tooth ring plate coupler link and arm bar as steering hardware, simple in structure, dependable performance, output torque is conveniently adjusted, and two three-wheel vehicles that can satisfy load carrying ability≤1.8T turn to requirement; Also be to be specially to be installed in the independently unsteady front fork design of existing pair of three-wheel vehicle on the independently unsteady front fork of two three-wheel vehicles, need not to change original structure.

The specific embodiment
Below in conjunction with accompanying drawing 1-3 the specific embodiment of the utility model is done and to be described in detail:
This steering hardware is made up of steering handwheel 1, steering handwheel adapter shaft 2, steering handwheel support 3, outer cylinder gear 4, internal tooth ring plate 5, connecting rod 6 and arm bar 7; Said steering handwheel adapter shaft 2 upper ends are connected with steering handwheel 1, and the lower end spline connects outer cylinder gear 4, and the stage casing is hinged through bearing and said steering handwheel support 3 upper ends; Said outer cylinder gear 4 one ends are provided with and outer cylinder gear 4 ingear internal tooths, and the other end and said connecting rod 6 are hinged, and outer cylinder gear 4 central portions are hinged to steering handwheel support 3 lower ends; Said connecting rod 6 two ends are hinged to an end of said arm bar 7 respectively.
This steering hardware is applicable to the unsteady front fork of the independence of two three-wheel vehicles; Two front forks 8 in the independently unsteady front fork of two three-wheel vehicles are fixed together through crossbeam 82 therebetween; Two front forks 8 are being connected to through bearing on the vehicle frame 10, and two front forks 8 all dispose bumper.Said steering handwheel support 3 is fixedly connected on the crossbeam 82 that is used to connect two front forks 8; The other end of said arm bar 7 is captiveed joint with the preceding fork shaft 81 of two front forks 8.Through above connection mode, this steering hardware will be installed on the independently unsteady front fork bridge of two three-wheel vehicles.
The principle of work of this steering hardware is; Pull steering handwheel 1 and drive outer cylinder gear 4 along 2 rotations of steering handwheel adapter shaft; Outer cylinder gear 4 drives internal tooth ring plate 5 along its central part hinged place rotation; Make the displacement that produces left and right directions with its pivotally attached connecting rod 6, the rotation of fork shaft 81 before this displacement converts into through arm bar turns to the front-wheel 9 that is installed on it thereby drive front fork 8.
The utility model is not limited to above-mentioned instance, in claims institute restricted portion of the utility model, and various distortion that those skilled in the art can make without creative work or revise the protection that all receives this patent.
