Description
Technical field
The present invention relates to variator locking gear level field, it is specially a kind of variator top grade and locks system in.
Background technology
Adopt single H handle structure and the variator of the rear odd-side of band, it is necessary to when odd-side is hung high-grade after ensureing variator, reverse gear wheel can not participate in transmission, avoids vehicle to hang shelves of falling down in a faint in advance process and causes the accident. For addressing this problem, adding a Ge Gao reverse gear lock mechanism above one grade of reverse gear shift fork, when odd-side is linked into high-grade district, high reverse gear lock works, and pins one grade of reverse gear shift fork, forbids shift fork motion extension one grade and reverse gear.
Currently, the variator of operating band odd-side all requires preliminary election, namely first stirs single H handle valve, allows single H valve complete height gear switch, and then neutral gear plucked by main case, and gas path control valve is ventilated, and auxiliary box cylinder realizes high and low shift conversion. Preliminary election is handled and can effectively be shortened odd-side switching time. But, adopting the gas path control valve of not band predischarge, after preliminary election, auxiliary box cylinder can move and cause odd-side out of supply. For solving preliminary election problem out of supply, have employed the gas path control valve of band predischarge.
Adopting the gas path control valve of band predischarge, although preliminary election problem out of supply can be solved, but bring another one problem, namely once main case is linked into shelves position, gas path control valve is vented, and after causing single H valve, high and low shift side gas is drained entirely, thus causes high reverse gear lock to lose efficacy.
Summary of the invention
For problems of the prior art, when the present invention provides one can not only ensure preliminary election, odd-side can not be out of supply, and the variator height reverse gear lock system that when can ensure that main case is linked into shelves position, height reverse gear lock can not lose efficacy.
The present invention is achieved through the following technical solutions:
A kind of variator height reverse gear lock system, comprises single H handle valve, predischarge gas path control valve, the horizontal shift bar of main case, check valve, single H valve, auxiliary box cylinder, high reverse gear lock and one grade of reverse gear shift fork; Single H handle valve inlet mouth and predischarge gas path control valve inlet mouth respectively air inlet end total with system be connected; 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, check valve blowing mouth is connected with single H valve inlet mouth, single H valve first blowing mouth is connected in the low-grade district of bar with having in auxiliary box cylinder, single H valve the 2nd blowing mouth is connected with the high-grade district of auxiliary box cylinder, and single H valve the 2nd blowing mouth is connected with high reverse gear lock simultaneously; The control end connection for transmission of the horizontal shift bar of main case and predischarge gas path control valve when shelves hung by main case; When ventilating in high reverse gear lock, high reverse gear lock is connected locking with one grade of reverse gear shift fork.
Preferably, the pipeline of check valve between predischarge gas path control valve blowing mouth and single H valve inlet mouth is arranged near single H valve.
Further, check valve and single H valve inlet mouth become one setting.
Preferably, the horizontal shift bar of main case is provided with to handle and dials head, by handling the control end connection for transmission dialling head 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 check valve along gas flow between predischarge gas path control valve and single H valve, thus when main case is linked into shelves position, predischarge gas path control valve exhaust channel is opened, it is merely able to the gas discharged between check valve and predischarge gas path control valve, ensure that in odd-side cylinder the stable of air pressure in high and low shift district, ensure effective locking of high reverse gear lock, thus avoid the inefficacy with high reverse gear lock of losing rank 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, and switching is easy, working stability.
Further, the distance between check valve and single H valve is shortened, or even by settings that become one, it is possible to ensure the abundant discharge to gas in pipeline, it is ensured that subsequent operations fast and stablize.
Further, head is dialled in utilization operation can better by the control end being delivered to predischarge gas path control valve of the motion accurate stable of horizontal for main case shift bar.
Further, by the concrete type selecting to single H handle valve and predischarge gas path control valve, simplify gas circuit structure, reduce cost, it is to increase the simplicity of operation.
