Embodiment Construction

[0083] Below in conjunction with accompanying drawing and embodiment describe in detail:

[0084] 1. Overall

[0085] The invention is an important part of the tire central inflation and deflation system of the off-road vehicle, and is matched with a special detection and control system.

[0086] The number of axles of the off-road vehicle involved in the present invention includes 2 axles, 3 axles and 4 axles. The principle of its module structure is the same. In view of the difference in the number of bridges, it can be designed into 2 axles by increasing or decreasing the channels and valves on the modules. Module assembly, 3-axle module assembly and 4-axle module assembly. The above-mentioned assembly is a 4-axle assembly.

[0087] Two, each component

[0088] 1) Air source intake straight-through interface (1)

[0089] As shown in Figure 7, the air source intake straight-through interface (1) includes a locking sleeve (1.1), a straight-through joint (1.2), a first O-r...

Abstract

The invention discloses a modularized central tire inflation / deflation control valve assembly of off-road vehicle, relating to a vehicle inflation / deflation technology. The invention is characterized in comprising a module (2), a first axle solenoid valve (3), a second axle solenoid valve (4), a third axle solenoid valve (6) and a fourth axle solenoid valve (7), a inflation / deflation solenoid valve (5), a first axle sensor (16), a second axle sensor (17), a third axle sensor (13) and a fourth axle sensor (10), a first axle relay valve (23), a second axle relay valve (22), a third axle relay valve (19), a fourth axle relay valve (18) and a relief shuttle valve (21), wherein, the module (2) is a rectangular metal plate fixed on a platform for the members; modularized structure is adopted, and the control units on the module can be added or removed according to the number of axles to meet the requirements of the specific vehicle model. The invention has the advantages of capacity of inflation / deflation and pressure measurement of single axle, multiple axles and the vehicle, high integration due to the assembly of various valve on the module, simple structure, reduced weight of vehicle due to less pipeline, and convenient installation and maintenance.

Description

technical field [0001] The invention relates to a vehicle inflation and deflation technology, in particular to a modelized off-road vehicle tire central inflation and deflation control valve assembly. Background technique [0002] The car tire central inflation and deflation system is a system that can detect and adjust the tire pressure at any time when the car is running (or stopped). Its main function is: when the car passes through deserts, coastal beaches, swamps, muddy ground and other soft ground and ice and snow roads, the system can quickly reduce the tire pressure and increase the ground contact area of ​​the tire. On the one hand, the tire subsidence and The soil resistance is reduced; on the other hand, due to the increase in the number of tire patterns embedded in the soil, the propulsion force of the soil is increased, the traction force is greatly increased, and the passability of the car is improved. [0003] When the height of the vehicle is limited by brid...
