The invention provides a crawler belt which comprises an elastic layer 10, a longitudinal line body layer 20 and a transverse line body layer 30, the elastic layer 10 is annular or strip-shaped, the longitudinal line body layer 20 extends in the length direction of the elastic layer 10 and is embedded in the elastic layer 10, and the transverse line body layer 30 extends in the width direction of the elastic layer 10 and is embedded in the elastic layer 10; an angle alpha is formed between a transverse single line body of the transverse line body layer 30 and a longitudinal line body of the longitudinal line body layer 20, and alpha is not equal to 0 degree, so that the torsional rigidity of the crawler belt is improved. A driving wheel transmits tensile force through the longitudinal line body layer 20 so that the elastic layer 10 of the crawler belt can move relative to a vehicle, the transverse line body layer 30 provides transverse rigidity for the crawler belt, and when the crawler belt is subjected to torsional force, the transverse line body layer 30 can provide counter-acting force opposite to the torsional force, namely the torsional force resistance of the crawler belt is improved, the transverse rigidity and the torsional rigidity of the elastomer crawler belt are improved, and the phenomenon that the crawler belt is separated from a loading wheel is prevented.
本发明提供了一种履带,该履带包括:弹性层10、纵向线体层20和横向线体层30,弹性层10为环形或者长条形,纵向线体层20沿弹性层10的长度方向延伸设置并埋设于弹性层10内,横向单线体沿弹性层10的宽度方向延伸设置并埋设于弹性层10内;其中,横向线体层30的横向单线体与纵向线体层20的纵向线体具有角度α,α≠0°,以提高履带的扭转刚度。驱动轮通过纵向线体层20传递拉力,以使履带的弹性层10相对车辆移动,而横向线体层30则为履带提供了横向的刚度,并使得履带受到扭转力时,横向线体层30可提供与扭转力相反的反作用力,即提高了履带的抗扭转力,提高了弹性体履带的横向刚度及扭转刚度,防止了履带脱出负重轮而发生脱带的现象。
