Description
Technical field
The present invention relates to Transmission gear locking field, be specially a kind of speed changer top grade and lock system in.
Background technique
Adopt the speed changer of odd-side after single H handle structure and band, must ensure after speed changer odd-side shift to a higher gear time, reverse gear is taken turns and can not be participated in transmission, avoids vehicle to hang in the process of advancing falling down in a faint grade causing the accident.For addressing this problem, above one grade of reverse speed fork, increase by a Ge Gao reverse gear lock mechanism, in the time that odd-side is hung into high-grade district, high reverse gear lock work, pins one grade of reverse speed fork, forbids that shift fork motion puts in the first speed and reverse gear.
Current, the speed changer of operation with odd-side all requires preliminary election, first stirs single H handle valve, allows single H valve complete height gear switch, and then main tank is plucked neutral gear, gas path control valve ventilation, and odd-side cylinder is realized high and low shift conversion.Odd-side conversion time can be effectively shortened in preselective control.But, adopting the not gas path control valve with predischarge, after preliminary election, odd-side cylinder can move and cause odd-side out of supply.For solving preliminary election problem out of supply, adopt the gas path control valve with predischarge.
The gas path control valve of employing with predischarge, although can solve preliminary election problem out of supply, has brought another one problem, once main tank is hung into gear, gas path control valve exhaust, cause single H valve after high and low shift side gas be entirely drained, thereby cause high reverse gear lock to lose efficacy.
Summary of the invention
For problems of the prior art, when the invention provides one and not only can ensureing preliminary election, odd-side can be not out of supply, and the high reverse gear lock system of speed changer that high reverse gear lock can not lose efficacy can ensure that main tank is hung into gear time.
The present invention is achieved through the following technical solutions:
The high reverse gear lock system of a kind of speed changer, comprises single H handle valve, predischarge gas path control valve, the horizontal shift level of main tank, one-way valve, single H valve, odd-side cylinder, high reverse gear lock and one grade of reverse speed fork; Single H handle valve suction port is connected with the total inlet end of system respectively with predischarge gas path control valve suction port; Single H handle valve blowing mouth is connected with single H valve control end; Predischarge gas path control valve blowing mouth is connected with check valve inlet, one-way valve blowing mouth is connected with single H valve suction port, single H valve the first blowing mouth is connected with the low-grade district that has bar in odd-side cylinder, single H valve the second blowing mouth is connected with the high-grade district of odd-side cylinder, and single H valve the second blowing mouth is connected with high reverse gear lock simultaneously; The control end connection for transmission of the horizontal gear level of main tank and predischarge gas path control valve in the time of main tank engage a gear; In the time ventilating in high reverse gear lock, high reverse gear lock is connected locking with one grade of reverse speed fork.
Preferably, one-way valve arranges near single H valve on the pipeline between predischarge gas path control valve blowing mouth and single H valve suction port.
Further, one-way valve and the single H valve suction port setting that becomes one.
Preferably, on the horizontal gear level of main tank, be provided with manipulation shifting block, by handling the control end connection for transmission of shifting block and predischarge gas path control valve.
Preferably, single H handle valve is normally closed two position two-way valve.
Preferably, predischarge gas path control valve is for often opening two position two-way valve.
Compared with prior art, the present invention has following useful technique effect:
The present invention by arranging one-way valve along gas flow between predischarge gas path control valve and single H valve, thereby in the time that main tank is hung into gear, predischarge gas path control valve exhaust passageway is opened, be merely able to discharge the gas between one-way valve and predischarge gas path control valve, ensure in odd-side cylinder the stable of air pressure in high and low shift district, ensure effective locking of high reverse gear lock, thereby avoided losing rank and the inefficacy of high reverse gear lock of odd-side high and low shift side; Coordinate predischarge gas path control valve to avoid the problem out of supply of odd-side after preliminary election simultaneously; System architecture is simple, switches easily working stability.
Further, by the Distance Shortened between one-way valve and single H valve, or even by the setting that becomes one, can ensure the abundant discharge to gas in pipeline, guarantee the quick and stable of subsequent operation.
Further, utilization operation shifting block can be better by the control end that is delivered to predischarge gas path control valve of the motion accurate stable of the horizontal gear level of main tank.
Further, by the concrete type selecting to single H handle valve and predischarge gas path control valve, simplify gas circuit structure, reduced cost, improved the simplicity of operation.
