Problems solved by technology

[0004] The purpose of the present invention is to overcome the problem in the prior art that the stability of the chassis can only be improved slightly by improving the tires and vehicle weight, and to provide an anti-skid chassis and a trolley with the anti-skid chassis. Under the same tire conditions, the positive pressure on the chassis can be greatly increased without increasing the mass, so as to increase the friction of the chassis and improve the stability of the chassis

Embodiment 1

[0030] The invention provides a non-slip chassis;

[0031] Such as figure 1 and figure 2 As shown, it includes an airtight chamber 3 installed below the chassis 1, at least one ducted fan 2 is arranged on the chassis 1, the air inlet of the ducted fan 2 communicates with the airtight chamber 3, and the exhaust port of the ducted fan 2 In communication with the outside atmosphere, the ducted fan 2 draws air from the airtight chamber 3 and discharges the air in the airtight chamber 3 toward the top of the chassis 1 .

[0032] By fixing the ducted fan on the chassis, the exhaust port of the ducted fan communicates with the outside atmosphere, and the air inlet of the ducted fan is connected with the airtight chamber, which is used to remove the air inside the airtight chamber to form air pressure inside and outside the airtight chamber Poor, when the atmospheric pressure around the side plate of the airtight chamber nearly cancels each other, the outside atmospheric pressure a...

Embodiment 2

[0040] The invention provides a non-slip chassis;

[0041] Such as image 3 and Figure 4 As shown, it includes an airtight chamber 3 installed below the chassis 1, at least one ducted fan 2 is arranged on the chassis 1, the air inlet of the ducted fan 2 communicates with the airtight chamber 3, and the exhaust port of the ducted fan 2 In communication with the outside atmosphere, the ducted fan 2 draws air from the airtight chamber 3 and discharges the air in the airtight chamber 3 toward the top of the chassis 1 .

[0042] By fixing the ducted fan on the chassis, the exhaust port of the ducted fan communicates with the outside atmosphere, and the air inlet of the ducted fan is connected with the airtight chamber, which is used to remove the air inside the airtight chamber to form air pressure inside and outside the airtight chamber Poor, when the atmospheric pressure around the side plate of the airtight chamber nearly cancels each other, the outside atmospheric pressure abo...

Embodiment 3

[0050] The invention provides a trolley with the anti-skid chassis;

[0051] Such as Figure 5 As shown, a kind of trolley comprises above-mentioned anti-skid chassis 1 and four wheels 5 that are connected with anti-skid chassis 1, and wherein front wheel is connected with steering rod 8, adopts steering motor 7 to drive steering rod 8 to move to realize the steering operation of the trolley, the trolley A battery 6 and a controller 9 are also included. When the car reaches a curve at high speed, the controller 9 starts to activate the ducted fan 2 on the chassis 1. After the ducted fan 2 works, the positive pressure on the chassis 1 is increased, that is, the friction force of the ground on the wheels is increased, and at the same time the steering The motor 7 drives the steering rod 8 to complete the steering of the trolley.

[0052] Because the trolley adopts the above-mentioned anti-skid chassis, when the trolley is running at high speed, the ducted fan installed on the ...

Abstract

The invention relates to the field of chassis and especially relates to a skid-proof chassis and a trolley with such skid-proof chassis. The skid-proof chassis comprises an airtight chamber installedunder the chassis; at least one fan is installed on the chassis; an air inlet of the fan is connected with the airtight chamber; an air outlet of the fan is connected with the external atmosphere; airis drawn from the airtight chamber by the fan and expelled out from the airtight chamber towards the above of the chassis. According to the invention, the fan is installed on the chassis so that airis drawn from the airtight chamber on the chassis by the fan to form differential pressure above and under the chassis; meanwhile, a reverse thrust is generated when the air is expelled upwards by thefan so as to further increase the stress on the chassis; under the same tire conditions, the positive pressure on the chassis can be increased substantially with little increase in mass, thereby increasing the friction and thus the stability of the chassis.

Description

technical field [0001] The invention relates to the field of chassis, in particular to an anti-skid chassis and a trolley with the anti-skid 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 stability of...
