Embodiment Construction

[0039] As shown in the figure, it is an embodiment of the present invention. The tire central inflation and deflation system of the present invention has two control states, automatic and manual.

[0040] 1. Automatic control status

[0041] In the automatic control state, the working state of the tire corresponding to the road surface is set in the system, which are:

[0042] Highway: The tire pressure is 0.37MPa, and the maximum allowable speed is 85Km / h

[0043] Off-road road: the tire pressure is 0.30MPa, the maximum allowable speed is 35Km / h

[0044] Desert: The tire pressure is 0.20MPa, the maximum allowable speed is 25Km / h

[0045] Emergency: The tire pressure is 0.15MPa, the maximum allowable speed is 20Km / h

[0046] Turn the automatic and standby switch on the operation panel to the automatic state, and the electrical automatic control state will start to work. The system will check the tire pressure by itself before driving. Set the working status of the required...

Abstract

The central air-charging and air-discharging system of tyre of heavy-duty cross-country car is formed from power supply, air source, operation control system, rotating sealing device, wheel valve and pipeline. The operation control system is formed from operation panel, electronic control device and electric control air valve group. The rotating sealing device is positioned between wheel hub and semixale tube and is formed from hermetic seal rubber ring, oil seal and isolation cover.

Description

(1) Technical field [0001] The invention belongs to the central inflation and deflation system of automobile tires, in particular to the tire central inflation and deflation system of heavy-duty off-road vehicles. (2) Background technology [0002] Due to the complex road surface of heavy-duty off-road vehicles, not only high road mobility is required on the highway, but also high off-road mobility is required on roadless ground. To make the vehicle have high mobility on the road, as far as the tire is concerned, it is necessary to increase the tire inflation pressure and reduce the energy loss of the deformation of the tire when rolling, which is also required to increase the speed of the vehicle, reduce the temperature of the tire and prolong the life of the tire. But when the car is running on the rough ground, the maneuvering speed of the vehicle is often limited by the vibration and impact suffered by the people and the vehicle. In order to improve the maneuvering spee...
