Abstract
A steerable wheeled assembly for a vehicle such as a harvesting or windrowing machine of the type adapted to be drawn over crop rows in the ground is disclosed. The assembly includes rotatable vertical members and a horizontal axle member which are arranged in a "C" frame supportingly connected to the vehicle and which provides clearance under the axle. Ground engaging wheels rotate on stub axles which pivot in steering movement when the vertical members are rotated. Steering or pivot arms are mounted on each of the vertical members and are connected together by a tie rod. A fluid power actuated cylinder connected to one of the arms is used to pivot the arm and stear the vehicle.
Claims14
A ground engaging wheeled assembly for a drawn or trailed vehicle comprising:
- steerable axle means including a horizontal member and a pair of spaced vertical housings jointed to said horizontal member forming a "C" frame, said vehicle supportingly connected to said "C" frame, a rotatable vertical member in each of said housings having an upper end extending from said housing and pivotally connected to said "C" frame and a lower end extending from said housing including spindle means on which a ground engaging wheel is rotatably supported and adapted to pivot when said vertical members are rotated;
- a pivot arm fixed to each upper end of said vertical members for rotating said members when said arms are pivoted;
- a tie rod pivotally connecting said arms and positioned between them whereby pivoting of one of said arms effects a corresponding pivoting of the other of said arms;
- pivoting means carried by said vehicle operatively associated with one of said arms for pivoting said arm and steering said wheeled assembly;
- turn indication means located on the vehicle operatively associated with said axle means for indicating the turning angle and steering direction of the wheels of said assembly;
- and
- pivot arm locking means for fixing the turn angle of said wheels of said assembly in a preselected position, said locking means being a rigidifiable extendible member connecting one of said arms to said horizontal member.

Steerable axle means for a ground engaging wheeled assembly of a trailed or drawn vehicle having a frame supported on said assembly comprising:
- a horizontal member supported on said frame in vertically spaced, laterally extending overhead relation to said vehicle;
- a pair of spaced apart, generally vertical rotatable members having upper ends coupled to said horizontal member and lower ends including pivotal means for rotatably supporting and pivoting the wheels of said assembly;
- steering means on said vertical members for rotating said members and pivoting said wheels;
- linkage means between said vertical members pivotally connected to said steering means;
- actuating means on said vehicle operably connected to said steering means for rotating said vertical members and steering said axle means;
- and
- severally componented visible indication means disposed on said vehicle for providing information respecting the turn angle and position of said wheels relative to said vehicle including a component which, in normal use providing said information, is relatively stationary and at least one additional component which, in normal use providing said information, is relatively movable with respect to said stationary component, said relatively stationary component being fixed to said horizontal member and comprising a gauge dial, the additional component being a pointer carried by said linkage means.
