    摘要： A one-piece molded plastic tread segment adapted for coupling with an identical tread segment without distortion of either member which comprises a one-piece body portion having a recessed opening defined by integral walls and adapted to receive the teeth of a driving means, said body portion having extending from either end thereof a plurality of tongue members, the area between any two tongue members defining a clevis area adapted to receive the tongue members of another identical member, each tongue member having an aperture molded therein and extending completely therethrough in a transverse direction, the configuration of the aperture of two of the tongue members, each of which is located at the extremities of and on opposite sides of the body portion, being such as to conform with the cross section of a pin, said cross section of said pin being substantially elliptical, said aperture in said tongue member being disposed such that it forms a predetermined angle phi along its major axis in relation to the horizontal plane of the body portion, the configuration of the apertures of the remaining or inner tongue members being substantially triangular such that a certain degree of rotational freedom is permitted said pin when inserted through said apertures. Endless tracks produced by the cooperative engagement of a plurality of tread members are especially suited for use on tracked vehicles, such as for example, snowmobiles.
