MOTOR, POWER UNIT, AND BULLDOZER

A motor includes a rotor including a rotating shaft extending along a center axis, a cylindrical rotor core provided outside the rotating shaft in a radial direction, and two discoid weight plates provided at two ends of the cylindrical rotor core in an axial direction, and a stator opposing the rotor in the radial direction. A radius of each weight plate is smaller than a radius of the rotor core, and a difference between the radius of the rotor core and the radius of each weight plate is larger than an air gap between an outside of the rotor core in the radial direction and an inside of the stator in the radial direction.

Self-detaching support frame system for an implement and method for using the same

A self-detaching support frame system for an implement designed to self-detach from a vehicle by actuation of a release handle located within arm reach of the driver is disclosed. The self-detaching support frame system for an implement allow the user to at least partially, preferably entirely, disengages the support frame assembly by activating a control, preferably a single control such as a handle located near the vehicle steering.

Rock blade
10472796 · 2019-11-12 ·

A movable blade assembly which can be attached to the front or rear of a vehicle and the height of the blade can be adjusted with respect to a roadway such that the blade only comes into contact with relatively large debris and moves them from the roadway.

SYSTEM AND METHOD FOR CONTROLLING TRACK SLIP OF A MACHINE
20190337386 · 2019-11-07 · ·

A method, system, and machine for controlling the output of an engine of a machine includes calculating the difference between a measured track slip based on track speed and ground speed and a calculated target track slip depending on track speed and chassis pitch, inputting the difference into a controller to determine a propulsion engine torque limit, and limiting the engine toque to the propulsion engine torque limit plus a steering system input torque.

Bulldozer

A bulldozer includes a blade disposed in front of a vehicle body. First and second cameras are disposed to the left and right of the vehicle body, respectively. A first optical axis of the first camera faces forward and downward. The first camera overlaps a left crawler belt as seen in a plan view of the bulldozer and is arranged to capture a first image of a gap between a lower edge of the blade and the left crawler belt. A second optical axis of the second camera faces forward and downward. The second camera overlaps a right crawler belt as seen in a plan view of the bulldozer and is arranged to capture a second image of a gap between a lower edge of the blade and the right crawler belt. A display is configured to display the first and second images side-by-side.

HYBRID LOAD BUCKET ASSEMBLY

A hybrid bucket assembly for a work vehicle having movable loader arms includes a reinforcing structure having a first edge plate, a second edge plate and at least two support members extending from the first edge plate. The reinforcing structure is for coupling the bucket assembly to the movable loader arms. The bucket assembly includes a double-wall bucket defining a volume for carrying material. The bucket is coupled to the at least two support members of the reinforcing structure, and the bucket has a leading edge coupled between the first edge plate and the second edge plate.

Bulldozer

A bulldozer has a protective structure. The protective structure includes a left pillar portion, a right pillar portion, and a beam portion. The left pillar portion is disposed to the left of a cab and extends in the up-down direction. The right pillar portion is disposed to the right of the cab and extends in the up-down direction. The beam portion is disposed above the cab and couples the left pillar portion and the right pillar portion. A first camera is attached to the left pillar portion and is disposed so that a first optical axis faces forward and downward. A second camera is attached to the right pillar portion and is disposed so that a second optical axis faces forward and downward.

Hydraulic lift cylinder mounting arrangement for track-type tractors

A track-type tractor may comprise an operator cab, an engine, a frame supporting the operator cab and the engine, and an implement configured to move a load. The track-type tractor may further comprise at least one hydraulic lift cylinder configured to raise and lower the implement. The hydraulic lift cylinder may include a head end, a rod end, and a cylinder barrel. The cylinder barrel may be connected to the backside of the implement, and the rod end may be connected to the frame.

Radiator guard and method of making

A radiator guard may include a front plate, a top plate, spaced side plates, gussets and yoke assemblies. The front plate may have a varied profile such that a first lateral width proximate a top of the front plate is greater than a second lateral width proximate a bottom of the front plate. The top plate may be angled relative to the front plate and the side plates may be fixed near the lateral sides of the front plate such that portions of the front plate proximate the top of the front plate extend laterally outwardly from the side plates. The gussets may be disposed on the rear surface of the face plate at these laterally extending portions and the yoke assemblies may be disposed on the front surface of these portions.

Position control system and method for an implement of a work vehicle
10392774 · 2019-08-27 · ·

A position control system for an implement of a work vehicle. The implement, such as a blade, is operatively connected to a push arm rotatably coupled to a frame of the work vehicle. A hydraulic actuator is operatively connected to the push arm and is configured to adjust the position of the push arm with respect to the frame. A controller generates a control command to adjust the position of the hydraulic actuator to thereby raise and lower the blade. A proportional quick drop valve, coupled to the hydraulic actuator and to the controller, directs a flow of fluid to the hydraulic actuator in response to the operator control command. The proportional quick drop valve reduces a drop speed of the blade, reduces cavitation of the actuator valves, and also reduces the pressure drop and fluid flow forces acting on the spools of the actuator valves.
