Principle of the present invention:
At present, the 2/2-way mechanically controlled valve that the secondary box of gearbox gear shift of major-minor case structure is used and the Pneumatic valve of two five-ways be in when work, easily causes that auxiliary box synchronizer loses rank.First reason is that odd-side cylinder does not have auto-lock function, and second reason is to have air pressure in two connection tracheaes between air valve.First solution, the auto-lock function of increase odd-side cylinder, but performance is not very reliable, and cost is very high, and efficiency of assembling is very low.Second solution, the endotracheal air pressure between two air valves of draining.But when odd-side cylinder does not have auto-lock function, in Vehicle Driving Cycle process, auxiliary box synchronizer may be lost rank.The 3rd solution, at two five-way air valve suction port front ends, increases one-way control valve, and the air pressure between two air valves can be drained, and the air pressure in two five-way air valves and cylinder retains, and auxiliary box synchronizer can be not out of supply.Equally, poor reliability, has increased cost, has increased the difficulty that tracheae is arranged, has reduced efficiency of assembling.
The air valve of 2/2-way of the present invention is that machinery is controlled, and the air valve of two five-ways is gas control, by the air valve of 2/2-way, is offered two five-way air valve air pressure and is controlled the break-make of air pressure.The mechanically controlled valve of 2/2-way changes by lift rod stroke, gives two five-way air valve air feed or dies.The air valve of two five-ways, by the control of preselector valve on speed changer, makes two five-way air valve commutations, thereby makes the conversion of auxiliary box synchronizer high and low shift.In order to guarantee auxiliary box synchronizer conversion smoothly, on two five-way air valves, must be provided with two relief openings.According to the structure after integrated and space, relief opening designs in the both sides up and down of two five-way air valves, and the breather plug of seal arrangement can be housed on relief opening, according to assembly space, considers size and the installing space of breather plug.
Working procedure of the present invention
As depicted in figs. 1 and 2, push rod 1 is under free state, and when the second suction port 37 does not have air pressure, air pressure enters from the first suction port 36, by the second air outlet 39, is flowed out.Air pressure in the first air outlet 38 gas circuits is discharged from first row gas port 40.
As shown in Figure 3 and Figure 4, after the certain stroke of push rod 1 compression, the source of the gas sealing of the first suction port 36, at this moment, passes into air pressure from the second suction port 37, and valve rod 19 is to bonnet 34 direction motions.
As shown in Figure 5 and Figure 6, after push rod 1 discharges, air pressure enters from the first suction port 36, by the first air outlet 38, is flowed out.Air pressure in the second air outlet 39 gas circuits is discharged from second row gas port 41.Realize gas circuit conversion.
Above content is only explanation technological thought of the present invention; can not limit protection scope of the present invention with this; every technological thought proposing according to the present invention, any change of doing on technological scheme basis, within all falling into the protection domain of the claims in the present invention book.
