Problems solved by technology
Different models and types of wheeled vehicles have different vehicle air source pressures and tire specifications. The debugging of tire central inflation system products needs to use the appropriate air source pressure and tire capacity to test different types of tire central inflation systems. Product inflation time, deflation time, pressure measurement accuracy and automatic pressure adjustment ability, when debugging the tire central inflation and deflation system, there is a status quo that the air source pressure and tire capacity change work intensity is high and the efficiency is low

Embodiment Construction
[0045] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0046] This embodiment provides a pneumatic control device for debugging the air source and air circuit of the tire central inflation and deflation system. The pneumatic control device performs pneumatic control through a solenoid valve, and the components of the pneumatic mechanism perform corresponding actions to realize the product of the tire central inflation and deflation system. During debugging, the change of air source pressure, tire capacity and the on-off of product connection air circuit can meet the needs of product debugging of central inflation and deflation system for various types of tires.
[0047] Such as figure 1 As shown, the pneumatic control device includes: an air circuit control valve group 1, a switching valve group assembly 2, a switching control valve group 3, an upper control tube 4, a lower control tube 5 and an airway tube 6;...

The invention discloses a pneumatic control device for debugging an air source and an air circuit of a tire central inflation and deflation system, comprising: an air circuit control valve group, a conversion valve group assembly and a conversion control valve group; the gas circuit control valve group is used for During the commissioning of the tire central inflation and deflation system, the change of the air source pressure and the on-off of the tire connection air circuit, the two or more product air channel interfaces on the air circuit control valve group correspond to the two or more air channel tubes one by one. Connected; two rows of tire connectors are provided on the conversion valve group assembly, which are respectively connected with tires of two capacities to realize the conversion of three tire capacities; the conversion control valve group is connected with the conversion valve group assembly It is used to control the conversion valve group assembly to realize the conversion of different air paths; wherein, more than two airway pipes are connected in parallel between the gas circuit control valve group and the conversion valve group assembly, and the number of tire joints in each row is more than two.
Description
technical field [0001] The invention relates to the technical field of vehicle debugging, in particular to a pneumatic control device for debugging an air source and an air circuit of a tire central inflation and deflation system. Background technique [0002] The tire central inflation and deflation system uses electronic control and pneumatic devices to complete the inflation, deflation, and pressure measurement of the wheeled vehicle tires in the stationary state or driving state, so as to meet the tire pressure requirements of the road that the vehicle will pass. Central tire inflation and deflation systems have been widely used in various types of wheeled vehicles. Different models and types of wheeled vehicles have different vehicle air source pressures and tire specifications. The debugging of tire central inflation system products needs to use the appropriate air source pressure and tire capacity to test different types of tire central inflation systems. Product inf...
