The present invention will be described in further detail with reference to the accompanying drawings:
referring to fig. 1 and 2, fig. 1 and 2 are distributed as a front view and a side view of a single H gas circuit and a power take-off protection gas circuit arrangement on a transmission; present single H gas circuit and power takeoff protection gas circuit contain 17 parts, do respectively: the air filter 1, the intake pipe 2, the low-grade trachea 3, first high-grade trachea 4, single H valve 5, first connecting screw 6, breather plug 7, single H valve support 8, connecting trachea 9, gas circuit control valve 10, three way connection 11, cylinder 12, power takeoff protection valve support 13, power takeoff protection valve 14, second connecting screw 15, power takeoff trachea 16 and the high-grade trachea 17 of second, the pneumatic valve is many, the function singleness and the gas circuit is arranged loaded down with trivial details.
Referring to fig. 3, fig. 3 is the utility model discloses a derailleur is equipped with the gas circuit picture of electromagnetism integrated valve, when adorning the electromagnetism integrated valve, the gas circuit includes air cleaner 1, intake pipe 2, low-grade trachea 3, first high-grade trachea 4, electromagnetism integrated valve 18 and cylinder 12, compares original gas circuit, has reduced 11 kinds of parts. The gearbox air valve is reduced in types, the integrated air valve can achieve multiple functions in the air circuit, the pipeline arrangement is clear, and the disassembly, the assembly and the after-sale maintenance are convenient.
When the transmission is equipped with an electromagnetic integrated valve, the main operations of the transmission comprise:
the auxiliary box is changed from high to low: when the main box is in a gear, the ejector rod of the electromagnetic integrated valve 18 is compressed, at the moment, the interior of the electromagnetic integrated valve 18 is in a mechanical locking state or a pneumatic locking state, no compressed air enters the air cylinder 6 through the first high-grade air pipe 4, and the auxiliary box is not converted; when the main box is in neutral gear, the ejector rod of the electromagnetic integrated valve 3 extends out to be in a free state, compressed air enters the air cylinder 6 through the first high-grade air pipe 4, and the auxiliary box completes conversion.
The auxiliary box rotates from low to high: when the main box is in a gear, the ejector rod of the electromagnetic integrated valve 18 is compressed, at the moment, the interior of the electromagnetic integrated valve 18 is in a mechanical locking state or a pneumatic locking state, no compressed air enters the air cylinder 6 through the low-gear air pipe 3, and the auxiliary box is not converted; when the main box is in neutral gear, the ejector rod of the electromagnetic integrated valve 18 extends out to be in a free state, compressed air enters the air cylinder 6 through the low-gear air pipe 3, and the auxiliary box completes conversion.
Parking power take-off protection: the parking power take-off switch controls the whole vehicle electromagnetic valve to supply air to the power take-off cylinder to enable the power take-off cylinder to be in gear, meanwhile, the switch supplies power to the Ampere plug on the electromagnetic integrated valve 18, so that the valve core inside the electromagnetic integrated valve 18 is locked to a low-gear position, at the moment, a driver switches the pre-selection valve shifting head to a high-gear position, as the valve core inside the electromagnetic integrated valve 18 is locked, a high-gear gas circuit cannot be switched on, the cylinder 12 cannot switch high gears, namely, the synchronizer cannot be in high gear, and the protection of the synchronizer of the auxiliary box.
Compare with the arrangement mode with current single H gas circuit and power takeoff protection gas circuit, the function that the electromagnetism integrated valve can realize is as follows:
1) the gas circuit of the electromagnetic integrated valve has the function of the existing single H gas circuit, can complete the switching of the auxiliary box, and can realize the protection of the synchronizer of the auxiliary box in the driving process. The protection function of the electromagnetic integration valve 18 on the auxiliary box synchronizer is completed by the following modes: in the driving process, the main box is in a gear engaging state, and at the moment, the internal mechanism is operated to compress the integrated valve ejector rod, so that locking is completed, and a protection function is realized.
The locking mode includes, but is not limited to, the following two modes: one is the position change of a valve core and a sealing ring of the electromagnetic integrated valve 18, so that the pneumatic locking of air inlet and air outlet is realized; one is mechanical lock-up after the spool of the solenoid integrated valve 18 moves.
2) The gas circuit of the electromagnetic integrated valve 18 has the functions of the existing single H gas circuit and the power takeoff protection gas circuit.
In the existing gas circuit, when a parking power take-off is carried out, the main box is in a neutral position, and when a driving power take-off switch and a parking power take-off switch of the whole vehicle are turned on, the driving power take-off switch controls a whole vehicle electromagnetic valve to supply gas to the cylinder 12, so that the cylinder 12 is switched to a middle position; the parking power take-off switch controls the whole vehicle electromagnetic valve to ventilate the power take-off protection valve 14 and the power take-off cylinder to be in gear, and meanwhile, the power take-off protection valve 14 moves under the action of air pressure through the inner valve core, so that the air passages of the first high-grade air pipe 4 and the second high-grade air pipe 17 which are connected with the two ends of the air valve are cut off. At this time, the driver switches the preselection valve dial to the high-gear position, and the high-gear gas circuit is cut off by the power takeoff protection valve 14, so that the cylinder 12 cannot switch the high gear, namely, the synchronizer cannot be connected with the high gear, and the protection of the auxiliary box synchronizer is completed.
When the air circuit of the electromagnetic integration valve is in a parking power take-off state, the main box is in a neutral position, and when a driving power take-off switch and a parking power take-off switch of the whole vehicle are turned on, the driving power take-off switch controls a whole vehicle electromagnetic valve to supply air to the air cylinder 12, so that the air cylinder 12 is switched to a middle position; the parking power take-off switch controls the whole vehicle electromagnetic valve to supply air to the power take-off cylinder to enable the power take-off cylinder to be in gear, meanwhile, the switch supplies power to an Anpu plug on the electromagnetic integrated valve 18, so that a valve core inside the electromagnetic integrated valve 18 is locked to a low-gear position, a driver switches a pre-selection valve shifting head to a high-gear position at the moment, a high-gear gas circuit cannot be switched on because the valve core inside the electromagnetic integrated valve 18 is locked, the cylinder 12 cannot switch a high gear, namely, a synchronizer cannot be in a high gear, and the protection of the synchronizer of the auxiliary box is completed.
The gas circuit of the electromagnetic integrated valve has better universality, solves the problem of gear falling of the original gas circuit, simplifies the gas circuit and reduces the complaint of gearbox failure caused by gear falling of an auxiliary box; the electromagnetic integrated valve is suitable for S10, S12, Volvo12 grades and existing 12 grades; the gas circuit of the electromagnetic integrated valve is convenient to assemble, the labor intensity of operators is reduced, and meanwhile, the cost is saved.
The structure of the electromagnetic integrated valve is described in Chinese utility model patent CN 201821795240.5.
The above contents are only for explaining the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby, and any modification made on the basis of the technical solution according to the technical idea of the present invention all fall within the protection scope of the claims of the present invention.
