楔形驱动轮存在着结构笨重、滚动阻力大、效率低等问题。为此,我们设计了一种无轮缘折面叶片轮,采用无轮缘叶片的形态和双排轮叶的结构,以提高附着性、脱泥性和改善平顺性;采用折面轮叶的结构以降低滚动阻力。此外,按照朗肯被动土压力理论对轮叶的间距、数目和长度作了分析和计算;导出了设计折面轮叶折转点及折转角的计算公式,以及合理确定驱动面倾角的理论计算公式。文中还介绍了这种新型轮的设计参数,并简述了在田间和楔形轮进行对比试验的结果。
Wedge-shaped drive wheel has the problem of bulky structure, large rolling resistance and low efficiency. To this end, we have designed a non-rimmed folding blade wheel, the use of non-rimmed blade configuration and double-row blade structure to improve adhesion, desilting and improve ride comfort; Structure to reduce rolling resistance. In addition, according to Rankine’s theory of passive earth pressure, the pitch, number and length of the blades are analyzed and calculated. The formulas for calculating the turning point and the turning angle of the folding flaps are derived and the theoretical calculation of the driving face inclination is reasonably determined formula. The article also introduces the design parameters of this new type of wheel and outlines the results of comparative tests conducted in field and wedge wheels.
