The invention provides a driving wheel assembly which comprises a driving wheel body and a plurality of driving tooth assemblies evenly arranged on the circumferential outer surface of the driving wheel body at intervals, each driving tooth assembly comprises a pin shaft and a roller arranged on the pin shaft in a sleeving mode, and the rollers are rotationally connected with the pin shafts; at least one annular oil storage groove is formed in the circumferential inner surface of the roller, the two ends of the pin shaft are fixed to the driving wheel body, and at least one of the two ends of the pin shaft is provided with an oil injection opening communicated with the oil storage groove. According to the driving wheel assembly, sliding friction at the meshing position of the track shoe and the driving wheel is changed into rolling friction through the shaft pins and the rotatable rollers, and therefore the service life of the driving wheel assembly and the service life of a track are prolonged. Meanwhile, due to the detachable structure of the driving tooth assembly, the driving tooth assembly can be rapidly replaced without disassembling the crawler chain, and therefore the maintenance cost of the driving wheel assembly is reduced.

    本申请提供了一种驱动轮总成,包括驱动轮本体和沿所述驱动轮本体周向外表面间隔均匀设置的多个驱动齿组件,所述驱动齿组件包括销轴和套设在所述销轴上的滚子,其中,所述滚子与所述销轴可转动连接,所述滚子周向内表面设有至少一个环形储油槽,所述销轴两端分别固定在所述驱动轮本体上,且所述销轴两端中的至少一端设有与所述储油槽连通的注油口。该驱动轮总成通过轴销和可转动的滚子,将履带板与驱动轮啮合处的滑动摩擦变更为滚动摩擦,从而提高驱动轮总成和履带的使用寿命。同时,驱动齿组件的可拆卸结构,无需拆卸履带链即可快速对驱动齿组件进行更换,从而降低了驱动轮总成的维修成本。
