CONTROL SYSTEM FOR DC BUS REGULATION
A device that includes a memory and a processor is disclosed. The processor may be configured to receive a control signal for operating a plurality of traction motors of a work machine. The control signal may include information relating to an actual speed of the work machine, a target speed of the work machine, and a generator speed of a generator operatively coupled to the traction motors. The processor may be configured to determine respective torque commands associated with the traction motors based on the actual speed and the target speed, and determine a generator power limit based on the generator speed. The processor may be configured to determine a threshold based on the respective torque commands and the generator power limit, adjust the respective torque commands based on the threshold, and cause the traction motors to be operated based on the adjusted respective torque commands.
Power train and construction machine
A first planetary gear set includes a first sun gear to which power is input from a hydraulic motor. The first planetary gear set includes a first carrier and a first ring gear. The first carrier and the first ring gear are able to rotate in conjunction with rotation of the first sun gear. A second planetary gear set includes a second sun gear configured so as to rotate integrally with the first carrier. A hydraulic clutch mechanism allows or prohibits the rotation of the first ring gear.
WORK MACHINE AND METHOD OF CONTROLLING THE SAME
A controller controls a first drive source and a second drive source based on a moving speed of a motor grader measured by a speed sensor and a turning angular velocity of the motor grader measured by an IMU, to thereby independently control a rotation speed of each of a right front wheel and a left front wheel.
MULTIFUNCTION BAFFLES AND WORK EQUIPMENT TRANSMISSIONS CONTAINING THE SAME
Multifunction baffles and work equipment transmissions containing multifunction baffles are provided. In various embodiments, the work equipment transmission includes a gearbox housing having an outlet port, a sump retaining a lubricant reservoir, and a first gear rotatably mounted in the gearbox housing such that a portion of the first gear is located below an upper surface of the lubricant reservoir. A multifunction baffle, which is installed within the gearbox housing, includes a circumferential shroud wall and an integrated suction tube. The integrated suction tube includes, in turn, a suction tube body integrally formed with the circumferential shroud wall, an inlet end portion in fluid communication with the lubricant reservoir, an outlet end portion in fluid communication with the outlet port, and a lubricant flow passage within the suction tube body and through which the lubricant is drawn from the lubricant reservoir.
Ingress/egress arrangement for machine
An ingress/egress arrangement for a machine comprises an operator cabin and a walkway system outside the operator cabin. The operator cabin can include a plurality of posts, including first post and a second post, and a door rotatably coupled to the first post so as to be movable between at a fully open position and at a fully closed position. An opening in the operator cabin between the first post and the second post defines a first operator ingress/egress point. The walkway system provides operator access to inside the operator cabin via the door and the opening, and provides operator access to outside the operator cabin. The door, in the fully open position, can restrict operator access toward a front of the machine and can allow operator access simultaneously to the walkway system and a second operator ingress/egress point.
DISPLAY SYSTEM FOR WORK VEHICLE AND GENERATION METHOD
The camera captures an image of a surrounding environment of a work vehicle and outputs image data indicative of the image. The shape sensor measures a three-dimensional shape of the surrounding environment and outputs 3D shape data indicative of the three-dimensional shape. A controller acquires the image data and the 3D shape data. The controller generates a three-dimensional projection model based on the 3D shape data. The three-dimensional projection model portrays the three-dimensional shape of the surrounding environment. The image is projected onto the three-dimensional projection model based on the image data, thereby generating display image data that represents a display image of the surrounding environment of the work vehicle.
INGRESS/EGRESS ARRANGEMENT FOR MACHINE
An ingress/egress arrangement for a machine comprises an operator cabin and a walkway system outside the operator cabin. The operator cabin can include a plurality of posts, including first post and a second post, and a door rotatably coupled to the first post so as to be movable between at a fully open position and at a fully closed position. An opening in the operator cabin between the first post and the second post defines a first operator ingress/egress point. The walkway system provides operator access to inside the operator cabin via the door and the opening, and provides operator access to outside the operator cabin. The door, in the fully open position, can restrict operator access toward a front of the machine and can allow operator access simultaneously to the walkway system and a second operator ingress/egress point.
Tensile force-limiting device for a working machine
A traction force limiting device for a working machine with a continuously variable transmission that comprises a variator for adjusting the rotational speed ratio of the transmission independently of the torque ratio of the transmission. The traction force limiting device has a traction force interface for providing information to determine a traction force of the working machine, a limit value interface for setting a traction force limit value of the working machine and a control interface for emitting a control signal to the variator. Additionally, the traction force limiting device has a computer unit designed, on a basis of information provided via the traction force interface, to determine the traction force, to compare the traction force determined with the traction force limit value set via the limit value interface, and to control the variator in such manner that the traction force does not exceed the traction force limit value.
WORK MACHINE AND METHOD OF CONTROLLING THE SAME
A controller controls a first drive source and a second drive source based on a rotation speed of a right rear wheel measured by a rotation speed sensor and a rotation speed of a left rear wheel measured by a rotation speed sensor, to thereby independently control a rotation speed of each of a right front wheel and a left front wheel.
BRACKET ASSEMBLY FOR SECURING CONDUITS OF A MACHINE
A bracket assembly for securing a plurality of conduits includes a base including at least one recess, the recess defined by a bottom surface and a pair of side surfaces and a securing member configured to mate with the base and extend across the recess to form a conduit-receiving area. The bracket assembly also includes at least one adapter coupled to the recess to reduce the size of the conduit-receiving area.
