Side slip-preventing auxiliary brake for goods van

Abstract

The invention relates to a side slip-preventing auxiliary brake for a goods van and belongs to the field of vehicle side slip prevention. The side slip-preventing auxiliary brake for the goods van comprises a goods van carrier and wheels, wherein the goods van carrier is arranged on the wheels, a side slip-preventing device is arranged below the goods van carrier and is hinged to the bottom end of the goods van carrier, and the side slip-preventing device vertically swings with the hinge end as the center and is in contact with the ground. The side slip-preventing auxiliary brake effectively reduces the probability that the goods van turns on its side under emergency braking. The side slip-preventing auxiliary brake is simple in structure, stabilizes the gravity center of the van, plays a braking effect and reduces the threaten of the goods van to other vehicles or persons.

Description

technical field [0001] The invention relates to an anti-skid secondary brake for a truck, which belongs to the field of vehicle anti-skid. Background technique [0002] The phenomenon that the wheels of a certain axle or the wheels of two axles move laterally (that is, swing to the side) due to braking, rotational inertia and other reasons of a moving car is called sideslip. Vehicle skidding, especially rear wheel skidding, poses a greater threat to safe driving, often causing vicious traffic accidents such as collisions, rollovers, and ditch drops. According to the statistics of traffic fatal accidents where the driver is mainly responsible for the driver in a certain province of our country, 40% of the accidents are caused by rear wheel skidding, and 50% of them occur when the driver uses the brake and turns. , should be given great attention. [0003] There are three types of car sideslips, four-wheel sideslip, front wheel sideslip, and rear wheel sideslip. The four-...

Problems solved by technology

The four-wheel skids rarely occur; the front wheel skids ease the steering angular velocity of the vehicle, and the danger is not great when the road surface is wide, and its centrifugal force is reduced by the front wheel skids, so it can generally be stopped, slowed down or even disappeared by itself; but the rear The risk of wheel side slip, especially lateral slip when turning, is extremely high, because it will increase the steering angular velocity, resulting in more severe slip, such as "locked drag", the slipperier the road surface, the longer the braking time, and the more slippery the wheel will be. Seriously, its centrifugal force (inertia rollover moment) is also increased due to sideslip, and when it is greater than the stable moment of vehicle gravity, it will roll over

[0008] Although the above anti-rollover support for vehicles is practical for most vehicles, there is a critical pressure on it, and when it reaches a certain limit, it will still cause rollover
