Description
Technical field
The utility model relates to speed changer, relates in particular to a kind of speed changer engage a gear servomechanism.
Background technology
The most of mechanical transmission that adopts of domestic heavy vehicle, its maneuverability pattern is divided into flexible shaft manipulation and stiff rodHandle, flexible shaft manipulation cloth compared with stiff rod manipulation is set up more convenient, and each producer is widely used at home.The gear selecting stroke of mechanical transmission is little, does not have the problem of load-bearing in manipulation, but for the machine of flexible shaft manipulationTool formula speed changer, speed changer model, gearbox arrangement position, flexible axle length all can have influence on speed changerPortability and comfortableness that engage a gear is handled; When gearbox arrangement position and driver's cabin distant or bending moreTime, speed changer engage a gear resistance is larger, and pilot control is difficulty particularly, therefore, is badly in need of solving.
Utility model content
The purpose of this utility model is for the problems referred to above, and a kind of speed changer engage a gear servomechanism is provided, withSolve gearbox arrangement position and driver's cabin distant or bending when more, speed changer engage a gear resistance is larger,Pilot control is the problem of difficulty particularly.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of speed changer engage a gear servomechanism, comprises engage a gear flexible axle, described engage a gear flexible axle with for controlling threeThe control stick of cross valve is connected, and the air inlet of described three-position four-way valve is connected with source of the gas, and three-position four-way valveThe first gas outlet is connected with the rod chamber of power-assisted cylinder, the second gas outlet of three-position four-way valve and power-assisted cylinderRodless cavity is connected, and the piston rod of described power-assisted cylinder and engage a gear arm are rotationally connected.
As a kind of preferred version of the present utility model, the piston rod of described power-assisted cylinder is by bearing pin and engage a gearArm is rotationally connected.
In the utility model, power-assisted cylinder is by the servo-actuated control of three-position four-way valve.
The beneficial effects of the utility model are that described a kind of speed changer engage a gear servomechanism can be easily, easilyRealize engage a gear, thereby effectively alleviated driver's working strength, improved driver's handling comfort.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of speed changer engage a gear of the utility model servomechanism.
In figure:
1, engage a gear flexible axle; 2, control stick; 3, three-position four-way valve; 4, air inlet; 5, the first gas outlet;6, power-assisted cylinder; 7, rod chamber; 8, the second gas outlet; 9, rodless cavity; 10, engage a gear arm.
Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by detailed description of the invention.Be understandable that, embodiment described herein is only for explaining the utility model, but not to this practicalityNovel restriction.
Please refer to shown in Fig. 1, Fig. 1 is the structural representation of a kind of speed changer engage a gear of the utility model servomechanismFigure.
In the present embodiment, a kind of speed changer engage a gear servomechanism, comprises engage a gear flexible axle 1, described engage a gear flexible axle1 is connected with the control stick 2 for controlling three-position four-way valve 3, air inlet 4 and the gas of described three-position four-way valve 3Source is connected, and the first gas outlet 5 of three-position four-way valve 3 is connected with the rod chamber 7 of power-assisted cylinder 6, threeThe second gas outlet 8 of cross valve 3 is connected with the rodless cavity 9 of power-assisted cylinder 6, the work of described power-assisted cylinder 6Stopper rod is rotationally connected by bearing pin and engage a gear arm 10.
In the time that driver pulls forward engage a gear flexible axle 1, control stick 2 is mobile 2mm left and right forward, 3-position 4-wayThe gas that the air inlet 4 of valve 3 enters is entered the rod chamber 7 of power-assisted cylinder 6 by the first gas outlet 5, and then bandThe piston rod retraction of moving power-assisted cylinder 6, thus after driving the engage a gear arm 10 being rotationally connected with piston rod, move; WhenDriver is during to pusher engage a gear flexible axle 1, and control stick 2 is mobile 2mm left and right backward, the entering of three-position four-way valve 3The gas that gas port 4 enters is entered the rodless cavity 9 of power-assisted cylinder 6 by the second gas outlet 8, and then drives power-assisted gasThe piston rod of cylinder 6 stretches out, thereby drives the engage a gear arm 10 being rotationally connected with piston rod to move forward.
By adopting above-mentioned speed changer engage a gear servomechanism, can realize easily, easily engage a gear, thereby effectivelyThe working strength that has alleviated driver, improved driver's handling comfort.
Above embodiment has just set forth general principle of the present utility model and characteristic, and the utility model is not subject toState embodiment restriction, do not departing under the prerequisite of the utility model spirit and scope, the utility model also has eachPlant and change and change, these variations and change all fall within the scope of claimed the utility model. This practicalityNovel claimed scope is defined by appending claims and equivalent thereof.
