Background technique
As everyone knows, the prior mechanical multispeed manual transmission is connected and composed by plug-in type odd-side, main tank and segmented odd-side, and the plug-in type odd-side is placed on the main tank front, becomes one with main tank; The segmented odd-side is added in the main-gear box back.The high and low retaining of plug-in type odd-side switches and high gear district, the switching of low gear district of segmented odd-side all are the control system that adopts mechanical stroke valve control gearshift cylinder, thereby the gas leakage point is many when switching, and high and low half retaining of plug-in type odd-side is switched and high gear district, the existence inefficacy in various degree when switch in the low gear district of segmented odd-side.
Summary of the invention
In order to solve the many problems of control system gas leakage point of mechanical type multispeed manual transmission gearshift cylinder, the utility model proposes the control system of speed changer circuit control gearshift cylinder.
For this reason, the technical solution of the utility model is: speed changer circuit control gearshift cylinder control system, comprise plug-in type odd-side gearshift cylinder, segmented odd-side gearshift cylinder, it is characterized in that: plug-in type odd-side gearshift cylinder passes through to be connected with gas receiver behind low gear solenoid valve, the high gear solenoid valve, and segmented odd-side gearshift cylinder is connected with gas receiver after organizing low gear solenoid valve, high gear solenoid valve by another; Gearshift axle head at the segmented odd-side is provided with the step axle journal, and step axle journal place is provided with position limit switch-segmented odd-side diverter switch, and position limit switch is electrically connected with control unit; Gearshift axle head at the plug-in type odd-side is provided with the step axle journal, step axle journal place is provided with high gear position limit switch, low gear position limit switch, have clutch switch at clutch pedal, in the gear change hand lever ball, be provided with plug-in type high to low gear preselection switch, after clutch switch, the series connection of plug-in type high to low gear preselection switch, be electrically connected with low gear solenoid valve, the high gear solenoid valve of plug-in type odd-side; Power supply is provided by Vehicular accumulator cell.
To improvement of the technical scheme, be in facia board, to be provided with high and low retaining tutorial light, high and low retaining tutorial light detects the signal of high gear position limit switch, low gear position limit switch respectively.
It is as follows to describe working procedure of the present utility model:
(1) the high and low retaining of plug-in type odd-side switches:
Switching between a, the same gear
1. select the high gear or the low gear of plug-in type high to low gear preselection switch;
2. the stepping on clutch switch is to range;
3. whether high gear on the tester dash board or low gear tutorial light are changed;
4. release the clutch pedal.
Switching between b, the different gear:
1. select the high gear or the low gear of plug-in type high to low gear preselection switch;
2. the stepping on clutch switch is to range;
3. gearshift;
4. whether high gear on the tester dash board or low gear tutorial light are changed;
5. release the clutch pedal.
(2) switch in the high and low retaining district of segmented odd-side
When the driver carries out the gear selection with gear change hand lever, the sliding opening of block selecting axle position limit switch, and the control of process ECU (Electrical Control Unit), high gear solenoid valve or low gear power of electromagnetic valve are connected, the gas circuit of solenoid valve is opened accordingly, the pressurized air of gas receiver is sent in high gear or the low gear cylinder switched automatically.
The beneficial effects of the utility model are as follows: because the control system that adopts position limit switch and electric control element to form is come control electromagnetic valve, thereby control gearshift cylinder is realized gearshift, do not adopt prior mechanical stroke valve, thereby the gas leakage point does not have substantially when switching, and high and low half retaining of plug-in type odd-side is switched and switch reliably in high gear district, the low gear district of segmented odd-side.And in facia board, be provided with the high and low tutorial light that partly keeps off, can play the effect of demonstration directly perceived.
