    摘要： A snow vehicle of the saddle-riding type utilizes essentially the same upper structure as a motorcycle but mounts a ski on the front fork for steering and an engine-driven endless belt track assembly for powering the device. The endless belt track assembly is arranged for mounting on a rear arm structure in order to maintain surface contact between the endless belt and the snow and thereby improve the operating efficiency of the vehicle. The arm may be pivotally mounted or integral with a rear fork pivotally mounted to the vehicle. An improved endless belt construction is described in which the belt is strengthened by core members and the driving cogs of particular configuration and disposed at prescribed locations with respect to the propelling lugs in order to maintain surface contact between the belt edge and the snow surface during cornering. Also disclosed are various forms of cover structures for the track assembly that prevent the scattering of snow from the belt onto the rider or vehicle parts. Grab rails attached to the rear swing arm elements facilitate manipulation of the vehicle in confined spaces. A stopper belt adjustment is also shown mounted to a rear fork with the stopper belt extruding to an articulated rear swing arm structure. The adjustment accommodates for adjustments to the drive chain for tensioning.

    摘要翻译： 骑马式的雪车采用与摩托车基本上相同的上部结构，但是在用于转向的前叉上安装滑雪板以及用于为设备供电的发动机驱动的环形带轨道组件。 环形带轨道组件布置成安装在后臂结构上，以便保持环形带和雪之间的表面接触，从而提高车辆的操作效率。 臂可以枢转地安装或与枢转地安装到车辆的后叉形成一体。 描述了一种改进的环形带结构，其中通过铁芯构件和特定构造的驱动齿轮来加强带，并相对于推进凸耳设置在规定位置，以便在转弯期间保持带边缘和雪面之间的表面接触 。 还公开了用于轨道组件的各种形式的覆盖结构，其防止雪从皮带上散落到骑车人或车辆部件上。 连接到后摆臂元件的扶手有利于在密闭空间中操纵车辆。 止挡带调节装置还被安装到后叉上，止动带挤压到铰接的后摆臂结构。 该调整可适应用于张紧的驱动链条的调整。
