Center tyre inflation/deflation system with tyre protecting function

Abstract

The invention belongs to the filed of vehicles, and in particular discloses a center tyre inflation / deflation system with tyre protecting function. An air source is communicated with an air inlet of a solenoid valve; an air outlet of the solenoid valve is communicated with a second air channel which is communicated with a tyre through a first air channel; the second air channel is provided with a low-pressure connection and high-pressure disconnection pressure switch and a low-pressure disconnection and high-pressure connection pressure switch which are connected in parallel; a third air channel communicated with the second air channel is arranged between the two pressure switches, and is communicated with an air inlet of another solenoid valve; the solenoid valve and the high-pressure disconnection pressure switch are all connected with a delay relay which is connected with the inflation gear of the switch; and the another solenoid valve and the high-pressure connection pressure switch are all connected with another delay relay which is connected with a deflation gear of the switch. The system avoids the participation of a singlechip, can conveniently inflate / deflate tyres of the whole vehicle, and has the tyre protecting function.

Description

technical field [0001] The invention belongs to the field of vehicles, and in particular relates to a tire central inflation and deflation system with tire protection function for off-road vehicles. Background technique [0002] The road surface of off-road vehicles is also relatively complicated, and often needs to be driven on muddy and soft roads. According to the theory of vehicle ground mechanics, under the condition of certain ground friction coefficient and other conditions, the larger the ground contact area of ​​the tire, the greater the ground traction force obtained by the vehicle. Also bigger. Therefore, by adjusting the tire pressure and changing the tire contact area, it can play a role in changing the traction of the vehicle. Therefore, the passing performance of the vehicle is enhanced to varying degrees with the degree of reduction in tire pressure. [0003] As far as tires are concerned, on hard roads, if the air pressure of the tires is too low, the defo...

Problems solved by technology

The latter adopts the single-chip microcomputer control mode. Although it makes up for the shortcomings of the manual system, due to the complexity of the hardware system and the addition of program control, the cost of the entire tire central inflation and deflation system is relatively high, which is inconvenient for large-scale operation. internal promotion
