Abstract: A telescoping axle arrangement is provided for an agricultural applicator having a frame supported above a ground surface by a ground engaging wheel operatively connected to the frame by the telescoping axle arrangement. A tubular first axle element, and a second axle element slidingly inserted into the first element operatively connect the wheel to the frame, and provide extension and retraction of the axle along a longitudinal axis of the axle. A cylindrical tunnel passing through the first element limits the extent to which the second axle element can be inserted into the first axle element. An inner end of the second axle element is contoured to extend at least partly under the cylindrical tunnel in the second axle element when the second axle element is inserted at a maximum allowed depth into the first axle element.

Abstract: A tie rod arm is provided for incorporation into a vehicle steering assembly. The tie rod arm has a grease cap portion with a steering knuckle connection formation and a grease seal cap. The steering knuckle connection formation is used to connect the tie rod arm to the body of a steering knuckle of the vehicle steering assembly. The grease seal cap receives the lower end of a kingpin of the vehicle steering assembly. The grease cap portion of the tie rod arm is integrally formed with an arm portion, which includes a tie rod connection formation to connect the tie rod arm to a tie rod of the vehicle steering assembly. A steering arm may also or alternatively be connected to the body of the steering knuckle and include an upper grease seal cap, which receives the upper end of the kingpin.

Abstract: The present invention relates, in general, to a steering device for tractor and, more particularly, to a steering device for a tractor for enabling front wheels of the tractor to be turned to an angle over or approximate to a right angle with respect to the longitudinal direction of the tractor by means of a driver manipulating a steering handle, thus making it possible to increase the steering angle of the front wheels and making the turning of the front wheels smoother, whereby the tractor can turn around in place and easily perform different kinds of tasks, for example, a task required in a limited space, a task where there is a need for turning the tractor around in place, etc.

Abstract: The present invention relates to a steering apparatus for turning front wheels of a tractor. More particularly, the present invention provides a steering apparatus for tractors which includes a steering cylinder provided with left and right cylinder rods which are extended and retracted to the left and the right by steering force transmitted by hydraulic pressure when the driver manipulates the steering wheel, wherein swing links are respectively hinged to ends of the left and right cylinder rods, thus forming a first four-bar link structure, and second four-bar link structures are respectively formed on left and right ends of the first four-bar link structure so that the front wheels can be turned, whereby an angle range within which the front wheels can be turned can be increased.

Abstract: An articulate vehicle comprises a first frame disposed at one of front and rear portions of the vehicle and a second frame disposed at the other of front and rear portions of the vehicle. The first frame supports a first transaxle apparatus supporting a first axle. The second frame supports a second transaxle apparatus supporting a second axle. Proximal ends of the frames with respect to the vehicle are coupled to each other through a coupling part so that the first and second frames are rotatable relative to each other around a vertical axis according to steering operation. An engine is mounted on the first frame. A first hydraulic motor is integrally assembled in the first transaxle apparatus so as to drive the first axle. A working vehicle is equipped at a distal side of the second frame with respect to the vehicle. A second hydraulic motor is integrally assembled in the second transaxle apparatus so as to drive the second axle.

Abstract: A harvester incorporating at least one force balanced shaker vibratory brush as the harvesting apparatus uses a sensing system connected to a plurality of spring feelers carried on a shaft to generate a torque value responsive to the location of the shape and position of a tree. The feeler springs may be of differing lengths to assist in tuning the harvester. Apparatus and a method for mounting the shaker head on the vehicle as well as system of steering the harvester are disclosed.

Abstract: A seal structure of a tie rod mounting portion in a center take-off type power steering apparatus structured such that respective inner ends of a pair of right and left tie rods are swingably connected to a leg portion of a T-shaped connection member. Both arm portions of the connection member are respectively connected to a rack shaft by a bolt passing through a guide shoe sliding within a notch groove formed along a lengthwise direction of a gear box housing, the respective inner ends of a pair of right and left tie rods laterally move in accordance with a lateral motion of the rack shaft while being guided by the guide shoe, a center portion of a dust boot is gripped between the guide shoe and both of the arm portions of the connection member by being passed through by the bolts.

Abstract: A motor vehicle steering box for use with light duty trucks and other vehicles is provided with a function generation means for specifically controlling Ackerman geometry by independently controlling left and right tie rod links. The invention may be employed regardless of outside ball joint location and in lieu of a conventional rack and pinion steering apparatus.

Abstract: A power steering device for a vehicle includes: a wheel-steering generator adapted to be connected to an axle case comprising a differential gear and a pair of right and left axles having a common axis; right and left steering knuckles adapted to be connected to the right and left axles, respectively, to attach right and left steering wheels thereto; right and left tie rods disposed between the right steering knuckle and the right piston rod and between the left steering knuckle and the left piston rod, respectively, to transmit force from the right and left piston rods to the respective steering knuckles, thereby steering the respective wheels; and right and left coupling members which couple the right and left tie rods with the right and left piston rods, respectively.

Abstract: An apparatus for use in turning steerable vehicle wheels (14, 16) includes first and second pistons (42, 44) which cooperate with a housing (46) to define first and second chambers (38, 40). A rotatable screw member (84) extends from one of the chambers (38) into one of the pistons (84). A valve (22) is connected with the screw member (84) and is operable between an unactuated condition and either one of two actuated conditions directing fluid pressure to the chambers. A steering linkage (18) is connected with the pistons (42, 44) at a location between the pistons. Upon operation of the valve (22) from the unactuated condition to the actuated condition, the pistons (42, 44) move in the chambers (38, 40) and turn the steerable vehicle wheels (14, 16). As the pistons (42, 44) move, a ball nut (86) connected with one of the pistons (42) effects rotation of the screw member (84) to operate the valve (22) toward the unactuated condition.
