Problems solved by technology
When the car is running at low speed, the friction between the tires and the ground is large, and the driver needs to use a large force to turn the steering wheel, which is easy to cause fatigue driving; when the car is running at high speed, the friction between the tires and the ground is small, and the driver The steering wheel can be turned easily, but due to the high speed of the vehicle, when the steering wheel is turned a lot, it is easy to cause sideslip or rollover, which has a great safety hazard

The invention discloses a multi-magnetic-pole driving device applied to a car booster. The multi-magnetic-pole driving device comprises a magnet fixedly connected with a booster rotating shaft, a magnetic conductor arranged on the outer side of the magnet in a sleeving mode and a coil installed at the bottom of the magnetic conductor; the input end of the coil is connected with the car control end, the magnetic conductor comprises a base connected with a booster shell, an outer magnetic conductor body located on the base and an inner magnetic conductor body located in the outer magnetic conductor body, a spacing exists between the inner magnetic conductor body and the outer magnetic conductor body, an annular cavity full of a magnetic field is formed between the inner magnetic conductor body and the outer magnetic conductor body, the magnet is located in the annular cavity, the outer surface of the inner magnetic conductor body is provided with multiple protruding magnetic poles, and the inner surface of the outer magnetic conductor body is provided with multiple protruding magnetic poles. According to the multi-magnetic-pole driving device, the resistance generated when the magnet rotates is increased or decreased by controlling the current magnitude of the coil, and therefore the technical effects that when a car runs at a low speed, a steering wheel can be easily rotated, and when the car runs at a high speed, the steering wheel can be stably rotated are achieved.
Description
technical field [0001] The invention relates to an accessory of an automobile booster, in particular to a multi-magnetic pole drive device applied to the automobile booster. Background technique [0002] The main function of the car booster is to assist the driver to reduce the intensity of the steering wheel and make it easier to drive. At present, the steering booster used in automobiles generally has two types: hydraulic type and electric type. The hydraulic type booster includes a steering hydraulic cylinder and a steering valve that controls the hydraulic pipeline of the steering hydraulic cylinder. The steering valve is connected with the steering wheel through a transmission mechanism. When the car is running at low speed, the friction between the tires and the ground is large, and the driver needs to use a large force to turn the steering wheel, which is easy to cause fatigue driving; when the car is running at high speed, the friction between the tires and the groun...
