Problems solved by technology

Therefore, the two driving wheels rigidly connected rotate at the same speed during the forward process, but the distance traveled is not equal. This friction will seriously affect the forward distance through accumulation, reducing the competitiveness

Abstract

The invention discloses a low-friction carbon-free trolley, which comprises a vehicle frame, a steering wheel and a driving wheel. The steering wheel and the driving wheel are on the same straight line. There is a bracket, a fixed pulley is set on the fixed frame at the top of the bracket, and a potential energy block is set inside; the frame is also equipped with a first rotating shaft and a second rotating shaft, the first rotating shaft is a stepped shaft, which consists of two cylindrical shafts with different diameters It is composed of brackets at both ends and fixed on the frame, and the potential energy block inside the bracket is connected to the flexible wire and the fixed pulley and the small cylindrical shaft of the first shaft; the second shaft is rigidly connected to the driving wheel, and the diameter of the second shaft is Smaller than the diameter of the large cylindrical shaft of the first rotating shaft, a flexible wire is wound on the second rotating shaft, and the second rotating shaft is connected with the large cylindrical shaft of the first rotating shaft through the flexible wire. The center of mass of the trolley is basically at the center of the geometric structure of the trolley, which reduces the supporting force of the driven wheel and helps reduce the friction with the ground.

Description

technical field [0001] The invention relates to a carbon-free trolley, in particular to a low-friction carbon-free trolley. Background technique [0002] Most of the existing carbon-free trolleys are provided with a steering wheel at the front, and two drive wheels with the same specification at the back; Due to the limitation of the structure and processing cost, the two drive wheels are simply rigidly connected by a shaft, and it is rare to have a differential. During the turning process of the carbon-free trolley with the above structure, because the two driving wheels rotate at the same speed but the forward speed is inconsistent, a large friction force is generated with the ground, the inner driving wheel slips backward, and the outer driving wheel slips forward. In the carbon-free car competition, the car turns more during the forward process. Therefore, the two driving wheels rigidly connected rotate at the same speed during the forward process, but the distance tra...
