摘要： A driverless transportation vehicle for piece goods has a chassis, a traction drive, a load-transfer device with a load-transfer drive, and a control system. The chassis has at least two wheels arranged on an axle and the traction drive is configured to drive the wheels. The load-transfer device picks up an item of piece goods and transfer its center of mass on the vehicle. The control system controls the traction drive to prevent the transportation vehicle from tilting about the axle of the chassis, while the driverless transportation vehicle balances on only the at least two wheels. The control system additionally actuates the load-transfer drive in such a way that the position of the center of mass of the cargo is adapted for a driving maneuver that is to be carried out.

摘要： Providing a movement control means for detecting a collision between a driving wheel and a step and a catch of a driven wheel by the step and temporarily changing a gravity center control region of a mobile device and moving the mobile device to pass over the step, and a mobile device including the same in order to prevent immovability under an environment having a step or an irregularity. Thus, a mobile device is configured to include: a lower body; an upper body provided in an upper portion of the lower body; a gravity center position adjustment means for changing an angle or a position of the upper body with respect to the lower body; and a driving wheel and a driven wheel provided in a lower portion of the lower body, and during movement in a direction in which the driving wheel is on a front side and the driven wheel is on a rear side, the gravity center position adjustment means inclines or moves the upper body to the front side when the driven wheel passes over the step, and moves the upper body toward an original angle or position after the driven wheel passes over the step.

摘要： A vehicle is provided with wheels fitted with pneumatic tires, and a vehicle body including wheel wells that surround the wheels. The pneumatic tire includes a plurality of protrusions on a sidewall portion that faces a predetermined wheel well side surface. An average normal vector of the wheel well side surface is inclined with respect to a rotation axis of the wheel. In such a configuration, when the vehicle is traveling and the tires are rotating, an air flow promotion effect and rectification effect are produced due to the protrusions on the sidewall portion, and negative pressure forms between the tire and the wheel well side surface.

摘要： A transmission system for an electric vehicle includes a gearbox which produces different rotation ratio between a drive motor and drive wheels during running of the electric vehicle, a differential which serves to absorb a power of the gearbox to overcome rotation speed difference between the drive wheels, and two wheel axles which are used to deliver the power to the drive wheels from the differential, the gearbox has a housing which is connected to a vehicle frame of the electric vehicle via a universal coupling. When the electric vehicle runs on a bumpy road and makes a turn, the vehicle frame is able to swing up and down and pivot left and right with respect to the gearbox housing, so as to reduce the bounce of the vehicle and dampen the centrifugal force caused tilt or roll of the vehicle, thus improving driving comfort and stability.
