Abstract

Provided is a trolley driven by gravitational potential energy and capable of walking along an S-shaped route. The trolley comprises a trolley body portion, a steering mechanism and a drive mechanism, wherein the trolley body portion is composed of a trolley bottom plate, a drive shaft support, a front fork installation frame, a weight support and a weight support installation frame. The drive mechanism is composed of a drive shaft, a locking threaded sleeve, a fixing shaft, a left drive wheel, a right drive wheel, a drive gear, a front wheel, a weight, a front trolley fork, a proportional fixed pulley and two ropes. The steering mechanism is composed of a driven gear, a connecting rod and a front trolley fork swing rod. The trolley has the following advantages that the gravity center of the whole trolley is descended to the lowest point, and stability of the trolley is facilitated; the rotation angle of the front wheel can be accurately changed by means of the method that the length of the connecting rod is adjusted, and accordingly the trolley can be conveniently debugged; by means of a conical winding groove in the drive shaft, requirements of the trolley in running for different torques can be changed, and the situation that the trolley speeds up in running is avoided; the trolley is simple in structure, convenient to operate, low in cost and capable of walking a long distance.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, in particular to a trolley driven by gravitational potential energy and capable of walking an S-shaped route. Background technique [0002] At present, there are various forms of obstacle-free carbon-free cars in the National College Students' Engineering Ability Comprehensive Competition. Quantitatively evaluate the results. This process has strict requirements on the design and processing of the trolley, especially the steering mechanism of the trolley, which must be disassembled and reassembled in a short period of time, and the trajectory of the trolley can be precisely controlled. At present, most of the trolleys participating in the competition are driven by a differential, and the direction of the trolley is controlled by the shape of the end cam. The disadvantage of this solution is that the processing cost is high, and the trajectory radius is adjusted by adjusting the leng...
