摘要： An adjustable ski track width mechanism allows adjusting the ski track between a narrow ski track width and a wide ski track width. The adjustable ski track width mechanism includes a steering mechanism that provides correct steering geometry and corresponding steering characteristics regardless of the narrow ski track width or the wide ski track width. The adjustable ski track width mechanism can be adjusted by the operator or automatically depending on operator preference or terrain conditions.

摘要： A front lifting equipment for an agricultural crawler tractor with considerable offset (D) of the front art relatively to an intermediate girder (1) whereto are fixed the track-layer assemblies (Cg), an axle (4) being provided at the rear. The equipment includes a reinforcing member arranged on each side of the tractor, fixed to the intermediate girder and to the rear axle, and formed by a flank (18g) substantially parallel to the tractor median vertical plane, and whereof the height is arranged to ensure satisfactory mechanical resistance in spite of a reduced thickness such that adjusting the narrow gauge track of the tractor is not hindered. A link (L) between the front part (19g) of the reinforcing flank and a fixing point located towards the tractor front is provided for picking up effort.
摘要翻译：一种用于农用履带式拖拉机的前起重设备，其相对于中间梁（1）具有相当偏移（D）的偏移（D），其中固定轨道层组件（Cg），后部设置有轴（4）。该设备包括设置在拖拉机的每一侧上的加固件，固定在中间梁和后轴上，并且由基本平行于拖拉机中间垂直平面的侧面（18g）形成，并且其高度被设置成确保尽管厚度减小，令机械阻力达到令人满意的程度，从而不会妨碍调整拖拉机的窄轨迹。提供加强侧翼的前部（19g）和朝向拖拉机前方的固定点之间的连杆（L），用于接收力。

摘要： A self-propelled boom vehicle has an extendible axle and an extendible steering mechanism which has an automatic steering synchronization system. The extendible axle has a hollow central support sleeve and telescopic arm sections. A single hydraulic extension axle is positioned inside the hollow central support sleeve and connects to and drives the telescopic arm sections between their retracted and extended positions. The steering synchronization system includes a pair of steering cylinders in a closed hydraulic circuit working in a master-slave arrangement and which operate inversely with respect to each other. A mechanical check valve is carried by each piston which allows excess hydraulic fluid to flow through the check valve to allow the piston to travel to the end of its stroke to resynchronize the steering.
摘要翻译：自行式动臂车辆具有可延伸的车轴和具有自动转向同步系统的可伸缩转向机构。可伸缩轴具有中空的中心支撑套筒和伸缩臂部分。单个液压延伸轴定位在中空中心支撑套筒的内部，并且在缩回和伸出位置之间连接并驱动伸缩臂部分。转向同步系统包括在主从装置中工作的闭合液压回路中相对于彼此反向运行的一对转向油缸。机械止回阀由每个活塞承载，允许多余的液压流体流过止回阀，以允许活塞行进到其行程结束，以使转向重新同步。
