摘要： PURPOSE:To enable driving of a vehicle with the same sensation as that of a general vehicle during running approximately similar to linear running and to enable rapid turn of a vehicle, by a method wherein front wheels are put in motion in linkage with control of rotation in the whole range of a steering handle, and in a range exceeding the specified range of each range, a car body is designed to be bent. CONSTITUTION:A front car body 10 having front wheels 14 and a rear car body 17 having rear wheels 19 are bendably coupled with each other around a vertical shaft 24, and the front wheels 14 are supported around their respective kind pins 12 so as to allow free steering. An electromagnetic valve 32 is actuated in linkage with control of rotation within the whole range of a steering handle 20, a front wheel steering cylinder 16 is actuated, and the front wheels 14 are steered around their respective king pins 12. When the steering handle 20 is controlled in a range exceeding a specified range, the front wheels 14 is steered, an electromagnetic valve 33 is actuated, and a car body bending cylinder 25 is expanded and contracted to bend the car bodies 10 and 17 around the vertical shaft 24. This constitution enabled driving of a vehicle with the same sensation as that of a general vehicle during running in a range approximately similar to linear running, and also permits facilitation of rapid turn of a vehicle in a paddy field.

摘要： PURPOSE:To prevent the danger of falling down and reduce the radius of turn by providing an Ackermann type steering function for either of front and rear wheels installed onto the chassis of an articulate type agricultural working car. CONSTITUTION:A chassis 1 is equipped with an articulate type steering function for the steering in bendable ways, in the horizontal direction, having the bendable part 4 of the chassis 1 as center. Rear wheels 3 are equipped with an Ackermann type steering function which can independently steer a rear axle 6. When the chassis 1 is turned by the articulate type steering function, front wheels 2 and rear wheels 3 are set so as to turn through a nearly equal locus around the turning center 0. Therefore, the radius of turn can be reduced, and the chassis does not turn easily. Front wheels 2 may be equipped with an Ackermann type steering function.
摘要翻译：目的：通过为安装在铰接式农用车底盘上的前轮和后轮提供Ackermann型转向功能，防止坠落的危险，并减少转弯半径。构成：机架1配备有用于在水平方向上以可弯曲的方式转向的铰接式转向功能，其中底盘1的可弯曲部分4为中心。后轮3配备有可以独立地引导后轴6的Ackermann型转向功能。当底盘1通过铰接式转向功能转动时，前轮2和后轮3被设定成几乎相等围绕车削中心0的轨迹。因此，可以减小转弯半径，并且底盘不容易旋转。前轮2可以配备Ackermann型转向功能。

摘要： PURPOSE:To hold a straight movement attitude accurately through simple operation by detecting the steering angle position of a vehicle body and stopping swiveling operation when a steering control means is set to a straight movement state. CONSTITUTION:The main body 4 of the vehicle 2 has the front part 6 and rear part 8 linked together pivotally through a pin 10, and a couple of fluid cylinder mechanisms 12a and 12b for steering are interposed between both parts. Those mechanisms 12a and 12b constitute a fluid pressure controlling means for a main-directional control valve 22, etc., and are controlled by a receiver on the basis from an operation signal from the steering control means. This main body 4 is provided with a steering angular displacement detector to detects its steering angle, and swiveling operation is stopped under the straight movement attitude control of the steering control means by a straight movement position signal from said detector to hold the straight movement attitude of the vehicle 2.

摘要： PURPOSE:To make the steering operation of a body foldable type vehicle satisfactory, by connecting a steering operation mechanism to a discharge flow control mechanism for a variable displacement type pump to prevent the generation of cavitation in a passage on the discharge side of the variable displacement pump. CONSTITUTION:A variable displacement pump 42 has one entrance/exit port 43 connected to the head side chamber 16 of a hydraulic cylinder 15 and to the rod side chamber of a hydraulic cylinder 17 through a passage 44, and another entrance/exit port 45 connected to the head side chamber 21 of the hydraulic cylinder 17 and to the rod side chamber 22 of the hydraulic cylinder 15 through a passage 46, and therefore, establishes a closed-loop circuit together with the hydraulic cylinders 15, 17 and passages 44, 46. Steering wheels 7 are connected through a link mechanism including a feed-back mechanism to a spool control section 57 in a servo control valve 56 which is disposed in a regulator 41 to control the port of a liquid chamber 48. Relief valves 58, 59 are disposed in the passages 44, 46 so that the variation rate of the discharge flow may be easily changed.

摘要： PURPOSE:To enable a sharp turning during an offset work and lessen controlling labor of an operator by interlocking an articulation control system and a steering control system with each other. CONSTITUTION:Oil, discharged from a working machine driving pump 23 flows into the first group of working machine control valves 26 to drive each working machine and is then sent from a carry-over port 31 into a tank via a solenoid valve 29. Another oil, discharged from a pump 24, flows into the second group of working machine control valves 27 and is sent to the tank. Said solenoid valve 29 is connected to a limit switch which is activated when a steering cylinder is operated, so that the solenoid valve 29 is energized by operating a steering device to interlock an articulation control system and a steering control system with each other.
