A two-wheel, self-balancing vehicle is disclosed. In one aspect, the two-wheel, self-balancing vehicle comprises a first wheel and a second wheel, the first wheel and the second wheel being spaced apart and substantially parallel to one another. The two-wheel, self-balancing vehicle further comprises a foot placement section connecting the first wheel and the second wheel. The two-wheel, self-balancing vehicle further comprises a set of position sensors in the foot placement section, the set of position sensors configured to generate inclination angle signals and velocity signals of the two-wheel, self-balancing vehicle. The two-wheel, self-balancing vehicle further comprises a first gravity sensor and a second gravity sensor in the foot placement section, the first gravity sensor and the second gravity sensor configured to generate weight signals and gravity angle signals. In addition, the two-wheel, self-balancing vehicle comprises a control logic configured to output control signals that control the movement of the two-wheel, self-balancing vehicle in response to the inclination angle signals, the velocity signals, the weight signals, and the gravity angle signals.

A paving machine for spreading, leveling and finishing concrete having a main frame, center module, bolsters laterally movably, and a crawler track associated with respective aft and forward ends of the bolsters. A bolster swing leg for each crawler track supports an upright jacking column. A worm gear drive permits rotational movements of the crawler track and the jacking column. A hinge bracket is interposed between each swing leg and a surface of the bolsters to enable pivotal movements of the swing leg. A length-adjustable holder engages the pivot pin on the hinge bracket and pivotally engages the swing leg. The holder permits pivotal motions of the swing leg in its length-adjustable configuration and prevents substantially any motion of the swing leg in its fixed-length configuration. A feedback loop cooperates with transducers keeping the crawler tracks position. The paving machine can be reconfigured into a narrowed transport configuration.

A working machine includes a controller configured or programmed to perform an automatic deceleration for automatically decelerating a left traveling motor and a right traveling motor rotated at a second speed by shifting from the second speed to the first speed, and to determine a deceleration threshold that is used for judging whether the automatic deceleration has to be performed or not.

A working machine includes a controller configured to determine a first deceleration threshold corresponding to each of a first traveling pressure, a second traveling pressure, a third traveling pressure, and a fourth traveling pressure, to perform automatic deceleration to reduce rotation speeds of a left traveling motor and a right traveling motor, and to judge whether to perform the automatic deceleration based on the determined first deceleration threshold, the first traveling pressure, the second traveling pressure, the third traveling pressure, and the fourth traveling pressure.

A working machine is provided, which includes a prime mover, a first traveling pump driven by power of the prime mover to supply operation fluid through a connector fluid tube, a traveling motor including first and second ports connected to the connector fluid tube, the traveling motor configured to be switched in a first speed and a second speed higher than the first speed, a first pressure detector to detect first traveling-pump pressure near the first port, a second pressure detector to detect second traveling-pump pressure near the second port, and a controller configured, with the traveling motor switched in the second speed, to automatically shift down the traveling motor from the second speed to the first speed, when a differential pressure between the first traveling-pump pressure and the second traveling-pump is equal to or more than a deceleration threshold.

A zero turn radius vehicle with a single steered wheel is described. The vehicle may include a pair of power transfer mechanisms driving a pair of wheels, an operator control mechanism for controlling the steering, speed and direction of the vehicle and a controller in communication with the operator control mechanism. A steerable wheel is located adjacent the front of the vehicle frame, on a first side of the vehicle frame and an electric actuator is connected to the controller for steering the front steerable wheel. A second, non-steerable front caster wheel is located on a second side of the vehicle frame. The controller controls the pair of power transfer mechanisms and the electric actuator based on operator input to the operator control mechanism.

A control system is disclosed for use in a zero turn vehicle, including an electric controller in communication with a pair of independent drive units. A joystick provides user inputs to the controller to control the rotational speed and direction of the drive units. The joystick includes a vertical stalk pivotable between a plurality of pivot positions, where each of the plurality of pivot positions corresponds to a particular rotational speed and direction of each of the driven wheels. A selector switch may be used to select one of a plurality of driving modes stored in the electric controller, wherein each of the plurality of driving modes maps a different set of speeds and directions for each of the driven wheels onto the plurality of pivot positions. The joystick may also rotate about a vertical axis to provide zero turn capability.

A new tracked vehicle arrangement with a main vehicle and a trailer, where each of the main vehicle and the trailer have a track assembly on either side, and the tracks of the trailer are driven by the prime mover of the main vehicle. In the longitudinal direction of the main vehicle, only a small fraction (less than 25%) of the length of the main vehicle's cab, which is mounted above the frame, overlies the main vehicle's track assemblies, whereas the fuel tank is located between the cab and the prime mover. In a widthwise direction of the tracked vehicle, the fuel tank at least partly overlies the right and left track assemblies. This provides a counterbalance for the trailer, which has a platform attached by a first pivotable connection to the frame of the main vehicle and by a second pivotable connection to the frame of the trailer.
