摘要： A snowmobile construction comprising a body frame and having slide rails suspended from the body frame through a front and rear suspension arm, and an endless track which runs under tension upon a drive and a plurality of driven wheels rotatably borne on the slide rails. The rear suspension has front and rear suspension arms which connect the body frame and the slide rails in parallelogram linkage fashion. Compression coil springs and shock absorbers are operatively mounted between the slide rails and the front and rear suspension arms. An inclined slide block and slot coupling interconnects the rear suspension arm and each slide rail to automatically react both front and rear suspension arms upon initial encounter of the slide rails with a snow bump at either end of the slide rail. This coupling also urges the snowmobile into an upwardly pitched condition upon acceleration with the forward ends of the slide rails digging into the ground surface for enhanced traction. The range of rearward and forward movment of the lower rear arm pivot in relationship to the slide rail is regulated to control the variations in track tension.
摘要翻译：一种雪地车辆构造，其包括主体框架，并且具有通过前悬架臂和后悬架臂从主体框架悬挂的滑轨，以及在驱动时在张力下延伸的环形轨道，以及可旋转地支撑在滑轨上的多个从动轮。后悬架具有前后悬挂臂，其以平行四边形连杆的方式连接主体框架和滑轨。压缩螺旋弹簧和减震器可操作地安装在滑轨和前后悬架臂之间。倾斜的滑块和槽连接件将后悬架臂和每个滑轨相互连接，以便在滑轨的任一端处的滑雪道初次遇到滑轨时自动地反应前悬架臂和后悬架臂。该联轴器还促使雪地车在加速时进入向上倾斜的状态，滑轨的前端挖入地面以增强牵引力。调节下后臂枢轴与滑轨相关的向后运动范围，以控制轨道张力的变化。

摘要： A suspension system mountable to the chassis of a snowmobile and about which an endless track is carried. The suspension includes a slide frame for engagement with a lower portion of the endless track and one or more springs for urging the slide frame downwardly away from the chassis. The suspension system also includes a downwardly angled suspension arm having an upper end pivotally mounted to the snowmobile chassis. The lower end of the arm is pivotally connected to the slide frame so as to permit limited longitudinal movement of the lower end of the arm with reset to the slide frame. An adjustable limit is provided for adjustably limiting the degree of longitudinal movement of the lower end of the arm with respect to the slide frame to adjustably control the range of orientations of the slide frame with respect to the snowmobile chassis.
摘要翻译：一种悬挂系统，其可安装到雪地车的底盘上并且携带有环形履带。悬架包括用于与环形轨道的下部接合的滑动框架和用于将滑动框架向下推离底盘的一个或多个弹簧。悬挂系统还包括向下成角度的悬挂臂，其具有可枢转地安装到雪地车底盘的上端。臂的下端枢转地连接到滑动框架，以便允许臂的下端的有限的纵向移动通过复位到滑动框架。提供了可调节的限制，用于可调节地限制臂的下端相对于滑动框架的纵向运动的程度，以可调节地控制滑动框架相对于雪地车辆底盘的取向范围。
