Ventral lifting anti-skid crawler device for wheeled motor vehicle
Technical Field
The utility model relates to a motor vehicle's supplementary safety device, concretely relates to wheeled motor vehicle (traveling and braking in road conditions such as rain, snow, ice) abdominal type lift anti-skidding crawler attachment.
Background
The prior wheeled motor vehicles, including new energy vehicles, intelligent control technology and the like, are known to achieve the purposes of driving and braking through a transmission system and a braking system by generating friction force between wheel tires and the ground. The magnitude of the sliding friction force f of the wheel is derived from the component N of the vehicle gravity on the vertical contact surface and the coefficient of friction μ (f = μ N) between the tire and the contact surface, which is determined by the size of the contact area between the tire and the ground and the roughness of their surfaces. The arc-shaped structural characteristics of the hub tires enable the vertical force-bearing point of the tires to be very limited in the friction area with the ground, and the effective area of each tire contacting the ground is about 100 multiplied by 215(mm2) taking a common off-road vehicle as an example. When the automobile runs on a rainwater, snow and ice road in rainy and snowy seasons, the friction force is greatly reduced, the phenomena of running and braking skidding are serious, and even the automobile completely fails, so that the driving is directly out of control, and the traffic casualty accidents are all caused.
