Description of drawings
Fig. 1 is the structural principle scheme drawing of the emergent gearshift of the present invention;
Wherein, S1 is a power change-over switch, and S2 is emergent shift switch, and D1, D2 are diode, and C1 ', CR ', CL ' are emergent gearshift electromagnetic valve, and C1, C2, C3, CR, CL, CH are the gearshift electromagnetic valve.
The specific embodiment
Below in conjunction with accompanying drawing emergent gearshift of the present invention is described further.
For the safety that prevents that unforeseen circumstances from taking place and improving vehicle ', existing vehicle is equipped with normal gearshift and emergent gearshift usually, if normal gearshift breaks down, just enable emergent gearshift, to guarantee the cruising of vehicle.
In order to make the more convenient operation of emergent gearshift, the present invention improves the emergent gearshift of vehicle, as shown in Figure 1, should comprise power change-over switch S1, emergent shift switch S2 and emergent gearshift electromagnetic valve by emergent gearshift, power change-over switch S1 adopts three-phase change-over switch, the common port of power change-over switch S1 links to each other with the 24V positive source of vehicle, can realize following three kinds of functions 1 by change-over switch S1) be the electric-control system power supply of vehicle; 2) outage; 3) be emergent gearshift power supply, above three kinds of functions cannot realize simultaneously, can only select a selection by change-over switch S1.When power change-over switch switches to emergent gearshift, power change-over switch S1 connects by lead and emergent shift switch S2, emergent shift switch S2 also adopts three-phase change-over switch in this example, can be implemented in 1 switching that keeps off, falls between 1 retaining and the neutral of advancing, emergent shift switch default conditions are neutral, the shift switch S2 that will meet an urgent need when needing gearshift switches to corresponding gear and sends gear shifting signal, the action of the corresponding emergent gearshift electromagnetic valve of control.Emergent gearshift electromagnetic valve adopts three in this example, be respectively the C1 ' that realizes hanging 1 retaining, realize the CR ' of reverse gear and realize ease ahead CL ', when working, hangs by gearshift two retainings in order to prevent to meet an urgent need, need between emergent shift switch S2 and emergent gearshift electromagnetic valve, install two diode D1 and D2 additional, the input end of diode D1 is connected with electromagnetic valve CL ' with emergent shift switch respectively, its mouth is connected with electromagnetic valve C1 ', the input end of another diode D2 is connected with electromagnetic valve CR ' with emergent shift switch respectively, its mouth is connected with electromagnetic valve C1 ', when emergent shift switch S2 switches to the position of 1 retaining that advances, just send gear shifting signal control emergent gearshift electromagnetic valve C1 ' and CL ' action, C1 ' and CL ' produce corresponding hydraulic control signal, make the comprehensive actuator action, 1 retaining of realizing advancing; When emergent shift switch S2 switches to down the position of 1 retaining, just send gear shifting signal control emergent gearshift electromagnetic valve C1 ' and CR ' action, C1 ' and CR ' produce corresponding hydraulic control signal, make the comprehensive actuator action, realize 1 retaining.By the installation of two diodes, make to need gearshift when advancing 1 retaining, signal can not flow to electromagnetic valve CR '; In like manner, when 1 retaining was extremely fallen in gearshift, signal can not flow to electromagnetic valve CL ' yet.
