5results about How to "Normal driving" patented technology

The utility model relates to the technical field of forklifts, in particular to an electric forklift. A frame assembly is connected to the driving assembly, a plurality of cavities are formed in a frame housing, batteries are installed in the cavities, a storage battery cover plate covers the upper portions of the cavities, an air cylinder is installed on the driving assembly, and a handle is installed on the driving assembly. The bracket is installed at the upper end of a driving support of the driving assembly, an air cylinder is installed above the bracket, and a supporting arm is installed at the lower end of the bracket. The shaft body of the shaft is sleeved with a long shaft sleeve, the two ends of the long shaft sleeve are each provided with a small rocker arm and a large rocker arm, the shaft body of the shaft between the large rocker arms and the small rocker arms is sleeved with a short shaft sleeve, and the thicknesses of the two ends of the small rocker arms and the large rocker arms are smaller than the thickness of the middle section, so that the weight of a vehicle is reduced, and the strength of the small rocker arms and the large rocker arms can be guaranteed; the service life of the forklift is prolonged, and breakage is prevented; the structure is simple, the driving wheel can be replaced only by disassembling the lower rotating shaft, the disassembling and assembling steps are reduced, and the battery is prevented from sliding out of the open hole or displacing from the open hole.

The utility model provides a remote control toy car wheel and a remote control toy car, and relates to the technical field of remote control cars, the remote control toy car wheel comprises a wheel body, a top plate and an anti-skid mechanism, the wheel body is used for being rotatably connected to a car body, and one end face of the wheel body is provided with a plurality of grooves at intervals along the same circumference; each groove extends to the outer circumferential surface of the wheel body; a plurality of grooves are formed in the wheel body, an anti-skid mechanism is arranged in each groove, each anti-skid mechanism comprises a spine structure, the spine structures are movably arranged in the grooves, and the tips of the spine structures are used for extending out of the outer circumferential surface of the wheel body under the action of gravity; the top plate is located on the side where one end face of the wheel body is located and fixedly connected to the vehicle body in the vertical direction, and the end, close to the ground, of the top plate is used for abutting against each spine structure so as to limit the corresponding spine structure to retract into the groove. Compared with the prior art, the wheel of the toy remote control car can enable the toy remote control car to normally run on a muddy and slippery road surface.

The invention provides a motor control method, a vehicle control unit, an electric vehicle and a medium, and relates to the technical field of electric vehicles. The method responds to a motor resolver signal fault message sent by a motor controller, outputs a whole vehicle fault alarm instruction to a vehicle instrument panel, and controls the whole vehicle to lower high voltage; in response to the input emergency switch starting signal, a braking depth signal and an electric switch opening degree signal of the vehicle are obtained; determining a corresponding braking state signal and a motor torque signal according to the braking depth signal and the switch opening signal; and the braking state signal and the motor torque signal are sent to a motor controller, so that the motor controller determines the rotating speed of a motor according to the braking state signal and the motor torque signal, and a driving motor of the vehicle is controlled according to the rotating speed of the motor. According to the method, the motor can be accurately controlled to run when the motor resolver signal is abnormal, so that the vehicle is controlled to run normally.

The utility model discloses a kind of fire engine chassis based on P3 parallel hybrid, including engine, clutch, automatic gearbox, driving motor, power takeoff, high-power water pump, power battery and transfer case, the engine is connected with automatic gearbox, and the engine is parallelly arranged with clutch, automatic gearbox and driving motor, the driving motor is electrically connected with power battery, the driving motor is connected with high-power water pump by power takeoff, the transfer case is used to disconnect coupling driving motor shaft, transmission front axle, transmission rear axle;The utility model is driven by the unique design of engine and driving motor parallelly, since driving motor has the characteristics of instantaneous output strong torque, cooperates with engine, so that the acceleration performance of fire engine is greatly improved, simultaneously in routine operation, driving motor can undertake power output task under partial working condition, reduce the running time and load of engine, to reduce fuel consumption.
