摘要： A work vehicle includes a hydraulic actuator, a hydraulic pump, an operation member, a control valve, an angular velocity corresponding value sensing unit, a notification component, and a controller. The actuator changes a steering angle based on a supplied fluid. The pump supplies fluid to the actuator. The operation member is operated by an operator when the steering angle is changed. The valve controls flow of fluid supplied from the pump to the actuator based on an amount the operation member is operated. The sensing unit senses a corresponding value corresponding to a steering angular velocity changed based on the flow of fluid. The notification component notifies that the corresponding value has reached a threshold value preset based on an upper limit of the steering angular velocity. The controller causes the notification component to perform a notification when it is detected that the corresponding value has reached the threshold value.

摘要： The present invention relates to a steering system and an independent suspension wheel-type heavy vehicle. The steering system comprises a steering mechanism for providing a steering force to wheels and a steering hydraulic assisting system for providing a steering assisting force overcoming a steering resistance moment from the ground to the wheels. According to the invention, by providing the steering mechanism for providing a steering force to wheels and by providing the steering hydraulic assisting system for providing a steering assisting force overcoming a steering resistance moment from the ground to the wheels, the steering resistance moment from the ground can be effectively overcome, and the vehicle is offered the steering capability for various places, as compared with a steering system only depending on the torque output by a steering gear or only depending on the torque output by the steering gear and a steering assisting follower.

摘要： A ratchet assembly may include a steer ring, a steer ring side structure, a steer cylinder bracket arm, a steer cylinder, a ratchet lock gear, a steering collar, a ratchet cylinder, a ratchet lock bar, and at least one sensor. When in a particular locked position, operation of the steer cylinder rotates the steer ring, the ratchet lock gear, and the steering collar. When in an unlocked position, operation of the steer cylinder rotates the steer ring around the ratchet lock gear.

摘要： An all-wheel drive vehicle with two steered vehicle axles. Each having a main steering cylinder with piston rods actively connected with the wheels. The main steering cylinders each have first and second chambers (30, 31) delimited by at least one piston element (34, 35) which moves longitudinally in the cylinder and is connected to the piston rod (28), such that adjusting pressure in the cylinder with an electric control unit, biases the piston elements and the piston rods to achieve specified wheel steering angles. Furthermore, a third chamber (32), which can be pressurized, is provided between a first and a second piston element (34, 35) of a main steering cylinder (26), which respectively delimit the first and second chamber (30, 31). The piston rods are sectioned, such that a first section is connected to the first piston element and a second section is connected to the second piston element.

摘要： A steering system for an articulated vehicle having both steerable axle or wagon-wheel and articulation steering. A steering system is provided which is responsive to the position and rate of change of position of the articulated body portions with respect to each other, the position and rate of change of position of the steerable axle with respect to the body portion on which it is mounted, and operator steering direction input and the rate of change of that input, so as to provide transitions between the two types of steering which enhances operation of the vehicle. The steering system is also responsive to operator inputs as to the function for which the vehicle is being employed. The system also has the ability to dynamically adapt to the vehicle conditions, such as for adjusting transition between steering modes based upon past perfomance.
