A velocity detecting radar unit that is easy to operate and to view so as to minimize distraction to the operator, particularly when in use in a moving vehicles includes a spotlight unit having a housing with a lens, a light source within the housing and a control wand pivotally mounting the housing for rotation about an axis and including an elongated tube adapted to extend through the windshield pillar of a vehicle. A radar antenna is mounted in the housing to be movable therewith and has a radar transmitting and receiving end extending from the housing oppositely of the spotlight lens. A display module is adapted to display velocity data and other information and is adjustable mounted to the tube at a location thereon remote from the spotlight housing. Similarly, an input or control module including function switches for providing function commands to a controller for the unit is provided and is adjustable mounted to the tube at a location thereon remote from the housing.

Velocity detecting system

Heat dissipation problems in a sealed radar antenna unit are avoided in a construction including a generally cylindrical body (10) of metal having opposed ends (12, 14) and an interior, cone shaped chamber (16). The cone shaped chamber (16) has a wide opening (18) at the end (12) at a narrow opening (20) at the end (14). A plurality of peripheral grooves (30, 32, 34, 36 and 38) extend about the periphery of the body (10) between the ends (12), (14) thereof to define heat dissipating fins (40) integral with the body (10).

The relative movement between the draft frame and the bowl member of a scraper bowl-lift apparatus is controlled by one or more bowl-lift motors. The longitudinal centerline of the motor passes through a spreader member of the draft frame. One end of the motor is pivotally connected to a shrouded motor support at a location above the spreader member while the other end of the motor is pivotally connected to a preselected portion of the bowl member. By so orienting the bowl-lift motor relative to the spreader, the entire draft frame apparatus is of improved strength and efficiency.

A hitch of a work vehicle having first and second vehicle portions has a first hitch apparatus for horizontally pivotally connecting the vehicle portions and a second apparatus with biasing for vertically, pivotally connecting the vehicle portions and suppressing vertical movement of one portion relative to the other.

A motor grader circle drive has an internal spur gear secured to the circle, and the internal gear is driven by one or two barrel worm gears, each of which in turn is driven from a hydraulic motor by an input worm and an input spiral gear keyed to the barrel worm gear, each barrel worm gear is journalled on a spindle in a support and is free to move endwise between a pair of radial flanges while being centered by a pair of belleville spring washers so as to compensate for backlash in each barrel worm gear and to permit substantially even distribution of driving force between the barrel worm gears when two are used. This structure operates at very low tooth pressures so as to permit the barrel worm gear to be made of a relatively soft material such as heat treated aluminum. The support, worm gear and input gears are made as a prefabricated sub-assembly, which is easily installed or removed; and using a soft material which wears much faster than the internal gear protects the latter from wear.

Motor grader circle drive

A motor grader is provided with a unitary circle drawbar and circle mounting structure in which the drawbar is a box-like beam which increases in width from front to rear, with the rearward portions of the beam top and side plates forming the forward part of the circle mounting structure which also serves as an integral circle drive housing that is fully enclosed except for a forward opening through which a driving connection is made with an internal gear on the circle. The rearward part of the circle mounting structure is semi-annular, is a hollow rectangle in cross-section with an external top flange, and has its front end integrally connected to the drive housing with the lower part of which is defines an outwardly open annular channel in which the circle is rotatably supported.

Scraper apron assembly

A scraper has a frame with first and second spaced apart side elements, a bowl, and an ejector system. The ejector system is connected to the bowl and is movable, relative to the bowl, for receiving or removing material into and from the bowl. The ejector system has first and second motors, each connected to opposite sides of the frame at locations outwardly of the first and second side elements. A power means is connected to and positioned between the first and second frame side elements.

Bowl and ejector apparatus

A motor grader including a main frame mounted on steerable wheels, a drawbar frame mounted on the main frame, a working implement carried by a circle gear rotatably mounted on the drawbar frame and a hydraulic control circuit is described. An improvement in the control of the working implement is disclosed in which continuous downward force is exerted on the circle gear at all times during operation by hydraulic rams. Preferred embodiments of the invention are described wherein the force is exerted by hydraulic means including wear surfaces in contact with the circle gear and wherein the hydraulic control circuit is adapted to provide automatic operation.

An improved support for mounting the grader blade assembly of a motor grader on depending support arms of the motor grader circle. A bearing housing structure which is several times wider than the height of the blade assembly consists of a transverse hollow structural member with integral upright bearing housings at its ends which are substantially wider than and pivoted on the arms so the structure may be tilted. Forwardly open lower jaws in the bearing housings have planar top and rear surfaces and front lower webs which are generally complementary to surfaces of a lower support rail on the blade assembly; and forwardly open upper jaws provide upper and lower front webs and a planar rear surface which are generally complementary to surfaces of an upper support rail on the blade assembly. Working forces are transmitted from the rails through the jaws and bearing housings to the support arms; and vertical forces are transmitted almost exclusively through the lower jaw. A hydraulic cylinder and piston unit for shifting the blade assembly endwise is mounted in the hollow structural member of the bearing housing structure and is removable therefrom endwise.

Motor grader support structure and side shift mechanism

Motor graders have a longitudinal main frame which carries a circle mounting bar that pivots on a horizontal axis at a connecting end and that has a carrying portion remote from its connecting end. A circle rotates on a vertical axis on the mounting bar carrying portion, and a grader blade is mounted on the circle. The present improved circle mounting bar is a box-like beam with internal vertical webs, and the beam increases in width from its connecting end toward a carrying portion of box-like cross section which is a separate part integrally welded to the beam. The shape of the beam in plan is intermediate between an isosceles triangle with its apex at the connecting end and a parabola with its apex at said end so as to give optimum uniformity of stress, throughout the length of the mounting bar, to both vertical and lateral forces.

Draw bar for a motor grader

A motor grader has a circle with integral, depending arms at the rear, and the lower ends of the arms extend forwardly so that blade mountings, comprising bearing housings pivoted at their lower ends to the extremities of the arms, extend upwardly in very close proximity to the fronts of the arms. Two hydraulic cylinder and piston units for tilting the blade mountings are carried in sleeves which are integral with and between the arms, directly behind the upper end portions of the blade mountings, which permits the use of very short stroke pistons that are well protected from damage by earth and rocks piled up by the blade. In addition the units are mounted in spherical bearing and socket means for limited universal movement within the sleeves. Further, the piston rods extend along shallow chords of a circle struck about the pivots which mount the bearing housings, so working forces are applied substantially axially to the piston rods in all positions of the bearing housings.

Motor grader blade mounting and tilt mechanism

An improved support and bearing for mounting the grader blade assembly of a motor grader on the depending support arms of the motor grader circle. Upright bearing housings are mounted on the arms and positioned forward thereof. Each housing has a forwardly open upper jaw and a forwardly open jaw the interiors of which are lined with anti-friction wear strips, and the blade assembly support rails are slidable in the wear strips, the latter being retained by detachable side plates on the housings. One of the lower wear strips is adjustable to maintain a snug sliding fit between the lower rail and all the wear strips in the lower jaws. The wear strips for the upper jaws are mounted in carriers that are vertically movable in the jaws to accommodate lack of parallelism in the support rails.

An apparatus for cutting an arcuately-shaped worm includes a support shaft adapted to carry a worm blank thereon and journalled in a frame which is mounted for pivotal movement about a fixed axis so that the worm blank may be simultaneously rotated on its axis and arcuately translated about the fixed axis relative to a cutter. The shaft is rotated by a drive means, and arcuate translation of the shaft is provided by a worm gear which is journalled in the frame and driven off the shaft, with the worm engaging a fixed gear segment, so the rate of rotation and of arcuate translation are coordinated.
