The present invention relates to a wheel tread-variable axle assembly for an agricultural vehicle and, more specifically, to a wheel tread-variable axle assembly, capable of changing a wheel tread of an agricultural vehicle such as a tractor. According to the present invention, the axle assembly (100) includes: an inner hub (110) including a first inclined surface (1101) provided on the outer circumference surface, and located on the outer surface of an axle (130); and an outer hub (120) including a second inclined surface (1201) provided on the inner circumference surface and corresponding to the first inclined surface (1101). The inner hub (110) includes a first inner hub (110a) and a second inner hub (110b). When the outer hub (120) is fastened with the first inner hub (110a) and the second inner hub (110b), the inner hub (110) is fixed to the axle (130) as the first inclined surface (1101) is pressed by the second inclined surface (1201). An installation position of a wheel (10) installed on the outer hub (120) is changed by controlling a position where the inner hub (110) is fixed to the axle (130).

    본 발명은 농작업차량용 차륜거리 가변형 차축 조립체에 관한 것으로서, 보다 구체적으로는 트랙터 등 농작업차량의 차륜거리(wheel thread)를 가변할 수 있는 차축 조립체(axle assembly)에 관한 것이다. 본 발명에서는, 외주면에 제1경사면(1101)을 구비하고, 차축(130)의 외면에 위치하는 이너허브(110); 및 내주면에 상기 제1경사면(1101)에 대응하는 제2경사면(1201)을 구비하는 아우터허브(120);를 포함하여 구성되며, 상기 이너허브(110)는 제1이너허브(110a)와 제2이너허브(110b)를 포함하고, 상기 제1이너허브(110a) 및 상기 제2이너허브(110b)에 상기 아우터허브(120)가 체결되면, 상기 제1경사면(1101)이 상기 제2경사면(1201)에 의해 가압되면서, 상기 이너허브(110)가 상기 차축(130)에 고정되며, 상기 이너허브(110)가 상기 차축(130)에 고정되는 위치를 조절하여 아우터허브(120)에 장착되는 차륜(10)의 장착 위치를 가변하는 것을 특징으로 하는 차축 조립체(100)를 개시한다.
