An anti-rollover apparatus and control method for heavy-duty vehicles with a pneumatic brake system includes an anti-yaw module, an anti-roll module, an electronic control unit (ECU) (10), a yaw velocity sensor (12), and a vehicle roll angle sensor (18). The ECU (10) controls solenoid valves (4, 9, 11, 19, and 24) to achieve braking of part of wheels to obtain anti-yaw torques and improve the yaw stability of the heavy-duty vehicles. The ECU (10) controls gas switch valves (21 and 22) to spray high-pressure gases recovered in brake chambers (1, 13, 16, and 26) out, anti-roll torques are obtained through the jet reactive force, and the roll stability of the heavy-duty vehicles is improved.

A three-wheeled vehicle includes a vehicle frame supported by a single wheel engaging the ground in the front and two wheels engaging the ground in the rear. The operator area of the vehicle may include seating for a driver and a passenger, one in front of the other. The three-wheeled vehicle is uniquely designed so that it can be easily modified by addition or removal of additional structures after it is purchased. The vehicle is ultra-narrow but achieves stability by unique mechanisms.

The invention discloses a lateral balancing system mounted on a variety of vehicle platforms, comprising vehicle body, chassis, supporting system, regulating system, the vehicle body is connected to chassis by supporting system; supporting system comprises two supporting columns which are relatively arranged, and inner side of the two supporting columns is provided with racks; regulating system comprises gyroscope, motor and gears matched with the racks, the gyroscope inducts vehicle running state and controls rotation of the motor, and controls inclination angle of vehicle body through the coordination of gears and racks. The invention assists the vehicle to keep vehicle body in a horizontal state when passing side slope, improves the vehicle’s smoothness and comfort, and avoid the vehicle rollover. The invention has better supporting effect and strong supporting force by adopting gears and racks, and can be applied and carried on multiple vehicle platforms, has good applicability and economic value.

A ground-contour-following autonomous obstacle avoidance mower for hillside orchards and a control method thereof are provided to achieve multi-angle cutting and low energy consumption in mowing operation through cooperation of a push rod motor and a connecting-rod rotating pair. A connecting rod is arranged and forms a flexible mechanism together with an upper base bearing, a lower base bearing and a base-connecting unthreaded shaft. The flexible mechanism interacts with the push rod motor to achieve ground contour following operation, so that the mower as a whole can conduct ground-contour-following mowing operation on a complex orchard terrain, with a better cutting effect than that of a traditional mower.

Sets of magnet assemblies coupled to the undercarriage of an amusement kart are provided. Each of the magnet assemblies can include: a suspension component coupled to the undercarriage; magnetic material coupled to the suspension component; and a rotating component coupled to the suspension component. Other sets of magnet assemblies can include a skid component coupled to the suspension component. Amusement park attractions are provided that can include: an amusement kart having one or more magnet assemblies coupled to an undercarriage of the amusement kart; and a track comprising iron plating sufficient to magnetically engage the one or more magnet assemblies. Amusement karts are also provided that can include: a frame supported by front and rear wheels; and complimentary side rails extending along both sides of the frame and between the front and rear wheels.
