Abstract

The invention discloses a negative pressure chassis and a small vehicle comprising the same, and belongs to the field of chassis. The negative pressure chassis comprises a chassis body and an airtight chamber fixed on the lower surface of the chassis body, wherein the lower end of the airtight chamber is of an opening structure, air draft devices are further arranged on the chassis body, and air inlets of the air draft devices communicate with the airtight chamber. According to the negative pressure chassis and the small vehicle comprising the same, the positive pressure borne by the chassis can be greatly increased without adding weight, and therefore the friction force of the chassis is increased, and the stability of the chassis is improved.

Description

technical field [0001] The invention relates to the chassis field, in particular to a negative pressure chassis and a trolley with the negative pressure chassis. Background technique [0002] With the rapid construction of expressways, viaducts, and expressways, vehicles can reach very high speeds under more road conditions. However, for the sake of safety, the driving speed of vehicles is restricted in many ways, especially for some ultra-small vehicles, even if there is a very open road condition and a better engine, it is not suitable to drive to a higher speed, because When the vehicle is running at high speed, once the direction deviates, the centrifugal force generated is also very large. Due to the limited weight of the chassis of a small vehicle, the dynamic friction force that can be provided is limited, which will easily cause the vehicle to skid and roll over in severe cases. , resulting in serious traffic accidents. [0003] At present, in order to improve the ...
