摘要： A wheel plate of a coupler for coupling a tractor and a trailer. The wheel plate has a lubricating arrangement for lubricating the sliding surfaces in the coupling. The lubricating arrangement includes a main groove formed in a central portion of the sliding surface of the wheel plate and surrounding the pivot shaft of the coupler, and a plurality of convolution grooves formed in the sliding surface of the wheel plate along convolution curves starting from and surrounding the main groove. The convolution grooves are communicated at their both ends with the main groove.
