    • A crawler-belt vehicle is a half crawler vehicle having front wheels furnished with tires, and crawlers on a rear wheel side composed of crawler belts extending between intermediate wheels and rear wheels. The front wheels are larger in diameter than the intermediate wheels and the rear wheels and, hence, have a large ground-contact surface area. Thus, while the vehicle is running on snow, the front wheels are not apt to sink in the snow to a greater extent with the result that the turning characteristic and breakthrough characteristic of the vehicle can be improved. The intermediate wheels may be set to toe in so as to prevent detachment of the crawler belts which would otherwise occur when the sub-beams are slightly flexed or deformed in a lateral outward direction under loads applied thereto while the vehicle is traveling at high speeds on the snow. In order to reduce side slips of the crawler belts, an intermediate line extending parallel to, and passing substantially intermediately between, an axle centerline of the intermediate wheels and an axle centerline of the rear wheels is arranged to meet with a turning center of the right front wheel, and a turning center of the left front wheel at the same point.
    • 履带式车辆是具有配备有轮胎的前轮的半履带式车辆,以及由后轮侧的履带,其由在中间轮与后轮之间延伸的履带构成。 前轮的直径大于中间轮和后轮,因此具有大的接地表面积。 因此,当车辆在雪上行驶时,前轮不容易在雪中下沉,结果可以提高车辆的转弯特性和突破特性。 中间轮可以设置成脚趾,以防止当车辆高速行驶时,在分支梁在施加到其上的负载下在横向向外的方向上稍微弯曲或变形时将发生的履带的分离 雪。 为了减少履带的侧滑,布置有平行于中间轮的轴心线和后轮的车轴中心线之间并且基本上中间延伸的中间线,以与​​后轮的车削中心相遇 前轮和左前轮的转动中心在同一点。

    • A suspension device in a crawler vehicle has a vehicle body, a pair of parallel spaced swing beams mounted on a rear portion of the vehicle body by a suspension for angular movement about a first axis located substantially longitudinally centrally thereof, a rear idle wheel rotatably supported on a front portion of each of the swing beams for rotation about a second axis, a rear drive wheel rotatably supported on a rear portion of each of the swing beams for rotation about a third axis, a crawler belt trained around the rear idle wheel and the rear drive wheel, and a front wheel rotatably mounted on a front portion of the vehicle body. The distance from the second axis to the first axis is greater than the distance from the first axis to the third axis. The second axis is positioned on a front end of each of the swing beams, and the third axis is positioned between the first axis and a rear end of each of the swing beams. Preferably, the distance from the second axis to the first axis and the distance from the first axis to the third axis have a ratio of about 2:1.
    • 履带式车辆中的悬挂装置具有车身,一对平行的间隔开的摆动梁,其通过悬架而安装在车身的后部,所述悬架用于围绕位于其大致纵向居中的第一轴线的角度运动,后空转轮可旋转地支撑 在每个摆动梁的前部分上围绕第二轴线旋转,后驱动轮可旋转地支撑在每个摆动梁的后部围绕第三轴线旋转;围绕后空转轮的履带; 后驱动轮和可旋转地安装在车身前部的前轮。 从第二轴到第一轴的距离大于从第一轴到第三轴的距离。 第二轴位于每个摆动梁的前端,第三轴位于每个摆动梁的第一轴线和后端之间。 优选地,从第二轴线到第一轴线的距离以及从第一轴线到第三轴线的距离具有约2:1的比率。
