Reversible tricycle

Abstract

The invention relates to a reversible tricycle which is provided with two steering wheels in the front a driving wheel in the rear. The reversible tricycle comprises a supporting mechanism and a steering mechanism, wherein the supporting mechanism comprises a tricycle frame, a fixing frame for the front two wheels and a rear chain stay; the steering mechanism comprises a direction column and a stand pipe and a steering knuckle which are connected with the support frame. According to the technical scheme, the supporting mechanism of the reversible tricycle is adopted, as a front suspension comprises a cavity which is arranged in the middle of the front suspension and is provided with a lateral front shock absorber, an anterior-superior cavity which is arranged on the anterior-superior portion of the front suspension, an anterior-inferior cavity which is arranged on the anterior-inferior portion of the front suspension and a rear-bottom cavity which is arrange on the rear bottom of the front suspension, the lateral front shock absorber and the supporting arm combination are both arranged on the middle cavity of the front suspension, thus, relative to a vertical front shock absorber, the position of the vibration and the center of gravity of the whole tricycle are reduced; in addition, the connection in a hinge mode instead of a cardan joint mode reduces the requirements for technology, and reduces the cost.

Description

technical field [0001] The invention relates to parts of a tricycle, in particular to a reverse tricycle with two steering wheels at the front and a driving wheel at the back. Background technique [0002] An inverted tricycle is a tricycle in which the front wheels have left and right wheels, and the rear wheels have a round, wherein the two front wheels have a steering function, and the rear wheels have a driving function. At present, the supporting structure of an inverted tricycle on the market includes a vehicle frame, a front two-wheel fixed frame, and a rear fork. The vehicle frame includes a rear section of the vehicle frame, a middle section of the vehicle frame, and a front section of the vehicle frame. The front two-wheel fixing frame, the rear part of the frame is movably connected to the rear flat fork, the front two-wheel fixing frame is fixed on the front two wheels, the rear center is fixed on the frame with a single shock-absorbing upper hinge, and the rear ...

AI Technical Summary

Problems solved by technology

At present, the supporting structure of an inverted tricycle on the market includes a vehicle frame, a front two-wheel fixed frame, and a rear fork. The vehicle frame includes a rear section of the vehicle frame, a middle section of the vehicle frame, and a front section of the vehicle frame. The front two-wheel fixing frame, the rear part of the frame is movably connected to the rear flat fork, the front two-wheel fixing frame is fixed on the front two wheels, the rear center is fixed on the frame with a single shock-absorbing upper hinge, and the rear center is fixed with a single shock-absorbing lower hinge On the rear fork, due to the difference between the frame and the front two-wheel fixing frame, the support structure of the entire inverted tricycle is unreasonable, and there are defects that the front suspension structure is scattered and not concentrated, and the space layout of the front section of the inverted tricycle frame is small. In addition, the front two-wheel steering device of the inverted three-wheel on the market includes a standpipe and a steering column connected to the support frame, and the support frame refers to the fixing parts of the fixed rotating mechanism parts such as the vehicle frame or the front suspension. , the steering column drives the steering arm of the universal joint to control the direction of the front wheels. Since the steering arms are connected by universal joints, and the cooperation between the universal joints requires a large rotation gap, resulting in a large operating gap and a slow corresponding speed ;In addition, there is also a rack-type transmission similar to that on a car. Although this method has a small rotation gap, the operating range is large. It usually requires several turns of the steering wheel to rotate the wheel direction to a suitable position, and it is not suitable for reversing tricycles. Steering handle, so it is necessary to provide a front two-wheel steering device suitable for inverted tricycles with fast response speed and small rotation clearance
