Electric haul truck
A zero emissions electrically powered haul truck is disclosed. The haul truck has a 40 metric ton hauling capacity and a form factor that allows the truck to travel through underground mines. The truck also includes a primary battery assembly that is externally mounted along the front and sides of the truck.
AVOIDANCE MODIFIER SYSTEM FOR COLLISION AVOIDANCE SYSTEM
An avoidance modifier system may be configured to modify operation of a collision avoidance system associated with a machine. The avoidance modifier system may include at least one inclination sensor and a modifier system controller configured to be in communication with the collision avoidance system. The modifier system controller may be configured to receive an inclination signal from the inclination sensor and determine an inclination angle at which the machine is operating relative to level operation. The modifier system controller may be configured to determine an adjusted ground plane angle indicative of a virtual ground plane on which the machine is operating, and communicate with the collision avoidance system, such that the collision avoidance system does not activate a braking device of the machine in response to an object sensor generating an object signal indicative of detection of an object between an actual ground plane and the virtual ground plane.
Method for controlling a gear shift in a transmission arrangement
A method is provided for controlling a gear shift from a forward gear to a reverse gear in a transmission arrangement, the method including the steps of: positioning a first locking mechanism and a first connecting mechanism at least in a partially engaged state for reducing a rotational speed of a planet carrier of a second planetary gear set; and positioning a second locking mechanism in an engaged state when a rotational speed of the planet carrier of the second planetary gear set is below a predetermined threshold limit.
TRACTION CONTROL FOR STEERING ARTICULATED POWER MACHINE
Disclosed embodiments include steering circuits utilizing a controllable cross-feed loop between left and right drive motor sides of an articulated power machine to reduce skidding caused by a turning operation in which an articulation actuator changes an articulation joint angle between a front frame member and a rear frame member of the power machine.
Evaluation device
An evaluation device includes a first display control unit that displays imaging data acquired by an imaging device on a display screen of a display device, and a second display control unit that displays on the display screen a guide display based on work vehicle data on a work vehicle imaged, to determine an imaging position of the imaging device.
AXLE DRIVE APPARATUS
An axle drive apparatus of the present invention includes an adapter unit that has an adapter case connectable to an axle drive case while supporting a first motor, an adapter input member connected to an output shaft of the first motor by connection of the first motor to the adapter case, an adapter output member that is connected to an axle drive input member of the axle drive apparatus by connection of the adapter case to an axle drive case, and an adapter power transmission mechanism that operatively transmits the rotational power of the adapter input member to the adapter output member. The axle drive apparatus is connectable to a vehicle frame through an axle drive case side frame connecting part and an adapter case side frame connecting part respectively provided at the axle drive case and the adapter case.
ELECTRIC DRIVER FOR WHEELED GROUND SURFACE MODIFYING MACHINE
A battery powered driver for propelling a wheeled ground surface modifying machine includes at least one wheel contacting a ground surface, a battery powered electric motor, control circuitry configured to manage delivery of electrical battery power to the electric motor to control a sped of the driver, at least one pedal attached to a pedal axle and tiltable in each of a forward and rearward direction with respect to the pedal axle, and at least one pedal tilt sensor configured to output one or more signals to the control circuitry indicating a degree of tilt of the at least one pedal. The control circuitry is configured to control the electric motor to accelerate the driver forward based on the one or more signals indicating a forward tilt of the at least one pedal, the electrical battery power delivered to the electric motor for forward acceleration proportional to a degree of forward tilt of the at least one pedal, and to control the electric motor to accelerate the driver rearward based on the one or more signals indicating a rearward tilt of at least one pedal, the electrical battery power delivered to the electric motor for rearward acceleration proportional to a degree of rearward tilt of the at least one pedal.
FRAME ACCESS APERTURE
Disclosed embodiments include power machine frames, and corresponding power machines such as skid steer loaders, which have fully arcuate access aperture features providing improved access to components within a chain case or otherwise positioned interior to the frame.
WORK VEHICLE AND CONTROL METHOD
A work vehicle includes an operation apparatus, a transmission having a plurality of gear positions, and a controller configured to control shift of a gear position of the transmission to a gear position equal to or lower than a shift upper limit position based on a vehicle speed of the work vehicle. The controller makes setting to raise the shift upper limit position by one position based on a first operation having been performed onto the operation apparatus. The controller changes the shift upper limit position from a first shift upper limit position immediately before a second operation different from the first operation to a second shift upper limit position based on the second operation having been performed onto the operation apparatus. The second shift upper limit position is higher than the first shift upper limit position by at least two positions.
Track assembly and a track driven vehicle equipped with such a track assembly
A track assembly (15) for a track-driven vehicle, whereby the track-carrying beam (15) is arranged to hold a front and a rear wheel (16), one of which is driving, a plurality of carrying wheels about which wheels a continuous track travels, the track-carrying beam (15) is elongated and terminated by a first and a second gable end. The track-carrying beam (15) comprises an integrated compartment (37) and an opening (36) in one (35) of said gables, whereby the compartment (37) communicates with the surroundings via said opening (36), and whereby the opening (36) is arranged to allow for insertion of a transmission device for driving of said driving wheel (16) via the opening (36) in the compartment (37).
