摘要： The vehicle according to the invention has a frame, a first running gear and a second running gear, wherein the two running gears are arranged on opposite sides of the frame and are mounted so as to be displaceable relative to the frame by means of hydraulic cylinders for changing the track width. Each hydraulic cylinder here includes a component fixed to the frame and a component which can be displaced relative to the frame, wherein the first and second running gears are each fastened to the displaceable component of the hydraulic cylinders, and the displaceable component of the hydraulic cylinders is displaceably guided in a guide on the frame, wherein the guide is designed to transmit forces between the displaceable component and the frame transversely to the displacement direction of the displaceable component.

摘要： The disclosure generally pertains to a robotic vehicle. An example robotic vehicle has a base platform that includes at least a chassis, an actuator, a sensor, and a controller. The chassis includes a first wheel that is attached to a first section of the chassis and further includes a second wheel attached to a second section of the chassis. The actuator has a proximal end attached to the first section of the chassis and a distal end attached to the second section of the chassis. The sensor is configured to obtain information associated with a stair structure located on a traversal path of the robotic vehicle. The controller evaluates the information obtained by the sensor and operates the actuator to vary a separation distance between the first section of the chassis and the second section of the chassis so as to enable the robotic vehicle to traverse the stair structure.

摘要： A system and method for controlling a vehicle, where the system includes independent driving modules each including a connection device having a rotation center spaced apart from a driving shaft in a forward/rearward direction and configured to connect the wheel and a vehicle body to move the wheel in the forward/rearward or an upward/downward direction, a shock absorber extending in a longitudinal direction and configured to contract or stretch, to connect the vehicle body and the connection device, and to restrict an upward/downward movement of the connection device, and a driving device configured to rotate the wheel, a road surface detector configured to detect a height displacement or a state of a road, and a controller configured to control velocities of the front and rear wheels of the independent driving modules, and to change a height of the vehicle based on the height displacement or the state of the road.

摘要： An on-board electronics system of an aerial work platform moves the wheels between a retracted and extended position by pivoting a respective arm. The method comprises the following successive steps: a) orienting each wheel tangentially to the pivoting path of the corresponding arm, b) moving the wheel by pivotally actuating the corresponding arm, and c) reorienting the wheel so as to enable another translation of the aerial work platform. The steps are performed in different orders between the wheels so that at any time at least one of the following conditions is complied with: —the brake system of at least one wheel is active, —at least one wheel is rotated by a motorised drive, —the orientation of the wheels relative to one another prevents any translation of the aerial work platform (1) on the ground as a result of gravitational force.

摘要： A split chassis system includes a first chassis base portion that is configured to house a first component and a second chassis base portion that is configured to house a second component. The second chassis base portion is positioned adjacent the first chassis base portion such that a first chassis coupling member included on the first chassis base portion is coupled to a second chassis coupling member included on the second chassis base portion. The split chassis system further includes a leveling subsystem that is coupled to the first chassis base portion and the second chassis base portion. The leveling subsystem aligns the first chassis base portion and the second chassis base portion such that the first chassis base portion and the second chassis base portion substantially maintain coplanarity when the first chassis coupling member is coupled to the second chassis coupling member.

摘要： A trailer for transporting a container has a frame mountable to a vehicle. The frame has a rear frame section mountable above a rear wheel assembly of the trailer, and a front frame section connected to and disposed forward of the rear frame section in a forward direction of travel of the vehicle. The front frame section has a king pin mountable to a hitch of the vehicle and a forward-most end. The forward-most end is moveable relative to the kingpin in a direction parallel to the forward direction of travel to extend and shorten a length of the front frame section between a fully-lengthened configuration and a fully-shortened configuration.

摘要： A replacement tailgate for the purpose of elongating the pick up truck may be installed on a truck bed wherein the replacement tailgate can be unfolded in order to elongate a length of the truck bed. The replacement tailgate may have front and rear shells that are used to support objects placed in the truck bed as well as act as the new tailgate when the truck bed length is elongated. Various panels may be unfolded in order to trap objects within the truck bed when the replacement tailgate is unfolded in order to elongate the truck bed length.
