Abstract:
A high clearance converter is used for converting a road vehicle, e.g. a pickup truck, to a high clearance vehicle, for example for agricultural use. The converter has front and rear frame components, each with two upright and ground wheels mounted on each of the legs. The front wheel hubs are mounted on the front frame component and the rear axle is mounted on the rear frame component. The front and rear frame components are coupled for relative rolling movement with respect to one another, allowing the frame to flex when travelling over uneven ground.
Abstract:
An axle assembly (10) is disclosed including a carrier (24) having side edges extending intermediate the frame rails (14) of a truck 12 and supports (28) secured to the frame rails (14). The carrier (24) is moved relative to the frame rails (14) by a screw (32) rotated about an axis by a hydraulic motor (36) to move a collar (40) threaded thereon and secured to the carrier (24). The carrier (24) is selectively locked in position relative to the frame rails (14) by simultaneously sliding first and second pins (44) slideably mounted to the carrier (24) into seats (58) fixed to the frame rails (14). The first ends of a pair of arms (66) are secured to an axle (60) having steerable wheels (62) while the opposite ends are pivotally mounted to the carrier (24). The arms (66) are pivoted relative to the carrier (24) by an actuator (70) to move the wheels (62) between ground-engaging and elevated positions. First and second arcuate brackets (84) are secured to the opposite ends of a rotatable shaft (80) and carry pedestals (86). A hydraulic cylinder (88) rotates the shaft (80) to place the pedestals (86) in a horizontal, transport position and a vertical, lock-out position with the lower ends of the pedestals (86) abutting with the axle (60) and their upper ends vertically in line with and for abutment with stop pads (94) secured to the supports (28).
Abstract:
An agricultural sprayer suspension includes four generally identical independent strut suspension assemblies each having a pneumatic spring supported above a strut shaft which is received within a strut journal connected to an adjustable axle. A scissors assembly located above the axle maintains wheel steer while facilitating vertical movement of the strut shaft within the journal. On non-steerable wheels, the lower end of the scissors assembly is connected to the journal to maintain a preselected wheel orientation. For steerable wheels, the lower end of the scissors assembly is connected to a hydraulic steering structure which allows axle adjustments for varying wheel tread. Similar construction of the steerable and non-steerable wheel assemblies reduces the number of different parts required and facilitates selective construction of sprayers with either two-wheel or four-wheel steering. A centrally located cab and sloping hood structure provide good visibility and direct viewing of all four wheels.
Abstract:
Soft low pressure type trailer wheels are supported on inverted V-shaped wheel tandem-type support members. Each of the wheel support members is pivotally supported on a side of the trailer and arranged such that the front wheels are supported about twice as far ahead of the pivot axis as the rear wheels are supported behind the axis. The pivot axis is arranged in the vicinity of the pivot point of the trailer. With this arrangement the front wheels may readily ascend a slope while "cranking" the rear wheels downwardly using the mechanical advantage provided by the longer forward support portions of the wheel support members. This tends to maintain the trailer relatively level. The arches provided by the inverted V-shaped wheel support members also provide sufficient ground clearance that the tops of the soft walled levees or the like type of undulations over which the trailer is towed, are not damaged to any extent. When descending slopes the front wheels can descend faster than the rear wheels tend to rise and thus again assist in maintaining the trailer in an essentially level (horizontal) state. Variable stoppers or limits are provided on each side of the trailer and can be set to damp the amount of rotation of the wheel support arms about their respective axes and slow and/or limit the decent of the front wheels. The prime mover which tows the trailer, is also provided soft low pressure tires.
Abstract:
Arm and fork mechanism for moving a refuse retainer with respect to a refuse container which has an opening in the upper portion thereof. Arms are pivotally mounted adjacent the refuse container. The arms are movable between a position adjacent a side portion of the refuse container and are also movable to a position above the refuse container. A plurality of forks is supported by the arms and angularly movable with respect to the arms. A fluid motor is operably joined to the arms and operably joined to the forks for angularly moving the forks with respect to the arms. The fluid motor is provided with a plurality of operation positions. Thus, the forks are angularly movable by the fluid motor to any one of a plurality of angular positions for lifting and dumping a refuse retainer.
Abstract:
A load transfer device for transferring a portion of the load normally carried by the rear wheel sets of a dump truck to the front wheel sets of the dump truck. The device is in the form of a tag frame which is pivotably mounted on the tailgate of a dump truck so as to be movable between an elevated position in which the tag frame is disposed closely adjacent the tailgate and a lowered position in which the wheel set of the tag frame is in the current engaging position.
Abstract:
In a road-going vehicle having rear wheel sets and a tag frame supporting a tag wheel set rearwardly of the vehicle for supporting a portion of the load of the vehicle and thereby removing a portion of the load previously carried by the rear wheel sets when in use, the improvement of mounting means on the vehicle for mounting the tag frame for longitudinal movement with respect to the vehicle between a retracted position closely adjacent the rear end of the vehicle in which the tag wheel set is elevated out of engagement with the road surface and a second extended position spaced rearwardly of the vehicle in which the tag wheel set engages the road surface and supports a portion of the vehicle load. The tag frame is driven in its reciprocating movement by drive means mounted on the vehicle and connected to the tag frame for driving the tag frame longitudinally with respect to the vehicle between the retracted and extended positions.
