Main purpose of the present utility model is to provide a kind of congee pot, make when cooking congee to be difficult for being burned, and simple in structure, rate of fault is low, with low cost.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind of secondary box of gearbox shifting control system, wherein, odd-side shift rod end is connected with piston-cylinder, forward and backward preceding tracheae, the back tracheae that is connected with gas receiver that be provided with respectively of cylinder, on preceding tracheae and the back tracheae solenoid valve and double H valve are installed, described solenoid valve is connected with the output terminal of the control unit of control switch control, and described double H valve links to each other with control switch.
Above-mentioned secondary box of gearbox shifting control system, wherein, described control switch comprises after speed changer neutral position switch, the segmented after the low gear switch of odd-side, the segmented the high gear switch of odd-side before odd-side high and low shift diverter switch, reverse gear speed probe, the plug-in type.
Above-mentioned secondary box of gearbox shifting control system wherein, is integrated with two position three-way valve on the clutch booster assembly, odd-side cylinder intake before the described two position three-way valve control.
Owing to have said structure, the utility model has following advantage compared to existing technology:
The utility model secondary box of gearbox shifting control system, reasonable in design, rate of fault is lower.
Description of drawings
Fig. 1 is the booster control schematic representation of the utility model preferred embodiment.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
The utility model secondary box of gearbox shifting control system is when the neutral gear position of low-grade (as being made as 1,2 grade), be that neutral position switch is when being in on-state, odd-side high and low shift diverter switch is in off state after the segmented, this signal enters control unit, control unit is given signal low-grade solenoid valve of odd-side to the segmented, the low-grade solenoid valve of odd-side is connected after the segmented, regulate double H valve simultaneously, this moment segmented after odd-side cylinder activation gas receiver, odd-side switches to low grade after making segmented, the low-grade switch connection of odd-side after the segmented; When the neutral gear position of handle position in high-grade (as being made as 3,4 or 5,6), be that neutral position switch is in on-state, odd-side high and low shift diverter switch is in on-state after the segmented, and this signal enters control unit, and control unit is given to the high-grade solenoid valve of odd-side after the segmented with signal, the high-grade solenoid valve of odd-side is connected after the segmented, regulate double H valve simultaneously, at this moment, odd-side cylinder activation gas receiver after the segmented, odd-side switches to top grade after making segmented, and the low gear switch of odd-side disconnects after the segmented.When neutral position switch was in off state, after 1 second, two solenoid valves on preceding tracheae and the back tracheae all disconnected.
When the odd-side system uses before the plug-in type of the secondary box of gearbox shifting control system of said structure, the handle ball push-button switch is pressed, step on clutch, relay in the circuit is low-grade closed according to the state of handle ball push-button switch at this moment, therefore, the low-grade solenoid valve of odd-side is connected before the plug-in type, gas receiver is connected in the cylinder of odd-side left side before the plug-in type, odd-side switches to low grade before making plug-in type, at this moment, the low-grade switch connection of odd-side before the plug-in type, the low-grade tutorial light of the preceding odd-side of the plug-in type of instrument panel is bright in the operator cabin; The handle ball push-button switch lifts, step on clutch, relay in the circuit is high-grade the disconnection according to the state of handle ball push-button switch at this moment, therefore, the high-grade solenoid valve of odd-side is connected before the plug-in type, and gas receiver is connected on the cylinder right side of odd-side before the plug-in type, odd-side switches to top grade before making plug-in type, at this moment, the high-grade switch connection of odd-side before the plug-in type, the high-grade tutorial light of odd-side is bright before the plug-in type of the instrument panel in the operator cabin.Can also be on the clutch booster assembly of preceding odd-side system an integrated two position three-way valve, its control principle as shown in Figure 1, oil enters from booster filler opening 1, discharge from booster oil drain out 32, booster suction port 11, booster relief opening 31, two position three-way valve suction port 12, two-position three way valve air gate 22, two-position three way valve outlet 33, this two position three-way valve cooperates half grade of valve of handle and half grade of odd-side relay valve of speed changer to control the air inlet of the cylinder of the preceding odd-side of plug-in type, the high and low half grade of switching of odd-side before realizing.Control the switch of this two position three-way valve by the booster piston stroke, the opening point of two position three-way valve, close close point and be associated with the booster piston position, make the thorough separation of clutch can before odd-side shift gears.
