摘要： The planetary steering differential includes first and second interconnected gear trains. First and second gear trains are used for rotating output members in the same direction at the same speed in response to rotating solely a first input and holding a second input stationary. Rotation solely the second input arrangement and holding the first input arrangement stationary the output members are rotated in opposite directions at the same speed. The first input arrangement is driven by a transmission, and the second input arrangement is driven by a reversible steering motor.

摘要： A self-aligning idler wheel assembly for a belted work vehicle includes a spindle having first and second radially extending flange portions. First and second self-aligning mechanisms are associated with a respective flange portion. The vehicle has an undercarriage assembly including a belt tensioning mechanism and a roller frame assembly. The first self-aligning mechanism connects the idler wheel assembly to the belt tensioning mechanism and the second self-aligning mechanism connects the idler wheel assembly to the roller frame assembly. The first and second self-aligning mechanisms provide self-aligning of the idler wheel assembly to ensure that the track belt runs straight and true.

Date Aug. 21, 1980A vehicle door latch assembly (16) is provided whereby a key (104) may be used to lock the door (10) and to prevent rotation of the outside door handle (20). A lock release lever (22) is provided inside the vehicle door for overriding the key lock (103) to permit the inside and outside handles (18,20) to operate to open the door. Even with the lock release lever (22) and the key lock (103) in the locked position, the inside handle (18) can be turned to move the lock release lever (22) to the unlocked position and to open the door. The outside handle (20) can now be used to open the door also. The outside handle (20) can also be released for operation by turning the key (104) in the lock (103) to the unlocked position.

摘要： A recoil and slack adjustment mechanism for tensioning an endless track chain of an undercarriage assembly of a work machine includes a ram assembly and an accumulator assembly. The ram assembly includes a ram housing having a ram chamber defined therein. A recoil ram is movably housed within the ram chamber. The recoil ram has a ram subchamber defined therein. The tensioning ram is movably housed within the ram subchamber and is coupled to a front idler roller of the undercarriage assembly. A check valve is disposed between the ram chamber and the ram subchamber such that fluid pressure from the accumulator assembly is selectively exerted on the tensioning ram thereby urging the front idler roller so as to bias the track chain of the undercarriage assembly. The recoil and slack adjustment assembly provides continuous, constant tensioning of the track chain, and does not require the use of live hydraulics.

摘要： A hitch assembly for a tractor is disclosed, which includes a rotatable carriage support that is carried on a fixed trunnion for providing oscillation of the hitch frame about horizontal first axis. The rotatably carriage support also pivotally mounts a hitch carriage about a second axis to provide the hitch assembly with the ability to articulate as well. Camming apparatus is also provided to progressively restrict the oscillation of the hitch frame as it is being raised and stop surfaces restrict articulation when the hitch frame is in its raised position. The articulation and oscillation ability of the hitch provides improved ease of steering and control of the tractor and improved ground contact of a ground-contacting implement on the hitch frame. A power-take-off shaft extends through said center of the fixed trunnion supporting the hitch mounting to permit simultaneous connection of the implement with the hitch and the power-take-off shaft for transmitting rotary power to the implement.
摘要翻译：公开了一种用于拖拉机的牵引组件，其包括可旋转的托架支撑件，其支撑在固定耳轴上，用于围绕水平第一轴线提供挂钩框架的摆动。可旋转的托架支撑件还将搭接托架绕第二轴线枢转地安装，以使挂钩组件具有能够铰接的能力。还提供凸轮装置，以逐渐地限制搭接框架在升起时的摆动，并且当搭接框架处于其上升位置时，停止面限制铰接。搭接的铰接和振动能力提高了拖拉机的转向和控制的便利性，并改善了搭接框架上接地工具的接地接触。动力输出轴延伸穿过固定耳轴的中心，支撑联结安装件，以允许工具与牵引力的同时连接以及用于将旋转动力传递到工具的动力输出轴。

摘要： Rollers used in the past have usually been cushioned by the attachment system. The present cushioned roller includes the cushioned member being an integral part of the roller. For example, the unique roller includes a pair of individual shell portions positioned at the ends of a shaft. The shaft and a collar which is mounted to a chassis includes a cushioning member positioned therebetween the shaft and the collar. The pair of individual shell portions are separately rotatable about the shaft and the rollers are isolated from the chassis and the rollers can osculate about the chassis. Thus, the roller is free to isolate about the chassis and each of the pair of individual shell portions are in contact with each of the inner portion and the outer portion of the inner surface of the belts. Furthermore, impact loads are absorbed by the cushioning member and increase the longevity of the roller and provide a better ride for the operator.
摘要翻译：过去使用的滚筒通常由附件系统缓冲。本缓冲辊包括缓冲构件，其是辊的整体部分。例如，独特的滚子包括位于轴的端部的一对单独的外壳部分。轴和安装到底盘的轴环包括位于轴和轴环之间的缓冲构件。一对单独的壳体部分可以围绕轴分开转动，并且辊与底盘隔离，并且辊可围绕底盘进行切割。因此，辊子可以围绕底盘自由地分离，并且一对单独的壳体部分中的每一个与带的内表面的内部部分和外部部分中的每一个接触。此外，冲击载荷被缓冲构件吸收并增加滚筒的寿命，并为操作者提供更好的乘坐。
