Detailed description of the invention
The present embodiment is that the automobile-used pattern that turns to of a kind of telescopic forklift switches ancillary system, there is fuel tank 11, propons steering cylinder 10, rear-axle steering oil cylinder 7 and solenoid directional control valve 5, fuel tank 11 is communicated with rear-axle steering oil cylinder 7 and propons steering cylinder 10 through oil absorption filter 1, gear type pump 2, turning gradient control valve 3, hydraulic steering gear 4, electromagnetic valve 5, and wherein solenoid directional control valve 5 has electromagnetic valve Y1 and electromagnetic valve Y2 (Fig. 2).
As shown in Figure 1, in the present embodiment, ancillary system comprises and turns to pattern switch auxiliary opening switch S1, magnetic induction proximity switch S2 and turn to mode selector switch S3.Power supply switches auxiliary opening switch S1, magnetic induction proximity switch S2 and rear-axle steering oil cylinder meta indicator lamp H1 ground connection through turning to pattern.Mode selector switch S3 is turned to be third gear switch, power supply connects the common port of third gear switch, third gear switch 0 grade end is through front-wheel steering mode indicating lamp H3 ground connection, I grade of end is through electromagnetic valve Y1 ground connection, II grade of end is through electromagnetic valve Y2 ground connection, and four-wheel steering mode indicating lamp H2 in parallel on electromagnetic valve Y1, on electromagnetic valve Y2, crab row in parallel turns to mode indicating lamp H4.
In this example, magnetic induction proximity switch S2 is arranged at rear-axle steering oil cylinder 7 midway location, and when steering cylinder piston rod is in meta (steered wheel rotating direction is just in time consistent with vehicle frame direction), magnetic induction proximity switch S2 closes conducting.
The principle of work of the present embodiment is as follows: arrange one at the bridge instrumentation frame place of vehicle and turn to pattern to switch auxiliary opening switch S1, when operator needs switching to turn to pattern, first can press this turns to pattern to switch auxiliary opening switch S1, then steering direction dish, when the piston rod of rear-axle steering oil cylinder is in meta, magnetic induction proximity switch S2 conducting, the rear-axle steering oil cylinder meta indicator lamp H1 being at this moment placed on instrument calibration place is bright.After operator sees that H1 lamp is bright, stop operating bearing circle, by turning to mode selector switch S3, selects to turn to pattern accordingly.
When turning to mode selector switch S3 to be in 0 gear, hydraulic steering gear 4 fluid out, through the meta of solenoid directional control valve 5, acts on propons steering cylinder 10, and now rear-axle steering oil cylinder 7 does not have fluid to pass in and out, and vehicle is in front-wheel steering pattern.Be arranged on and turn to the front-wheel steering mode indicating lamp H3 on mode selector switch S3 bright, the current vehicle of prompting operator is in front-wheel steering pattern.
When turning to mode selector switch S3 to be in I gear, electromagnetic valve Y1 conducting.Rotate clockwise bearing circle when vehicle advances, hydraulic steering gear 4 fluid out, first through the right chamber of rear-axle steering oil cylinder 7, promotes rear-axle steering oil cylinder 7 piston rod toward left movement, and trailing wheel is turned left side-sway.The left chamber of rear-axle steering oil cylinder 7 fluid out acts on the right chamber of propons steering cylinder 10 through solenoid directional control valve 5, the piston rod promoting propons steering cylinder 10 is turned left lateral movement, and front-wheel is turned right side-sway.Vehicle is in four-wheel steering pattern.Be arranged on and turn to the four-wheel steering mode indicating lamp H2 on mode selector switch S3 bright, the current vehicle of prompting operator is in four-wheel steering pattern.
When turning to mode selector switch S3 to be in II gear, electromagnetic valve Y2 conducting.Rotate clockwise bearing circle when vehicle advances, hydraulic steering gear 4 fluid out, first through the left chamber of rear-axle steering oil cylinder 7, promotes propons steering cylinder piston rod and to turn right motion, and trailing wheel is turned right side-sway.The right chamber of rear-axle steering oil cylinder 7 fluid out acts on the right chamber of propons steering cylinder 10 through solenoid directional control valve 5, the piston rod promoting propons steering cylinder 10 is turned left lateral movement, and front-wheel is turned right side-sway.Vehicle is in crab row and turns to pattern.Be arranged on and turn to the crab row on mode selector switch S3 to turn to mode indicating lamp H4 bright, the current vehicle of prompting operator is in crab row and turns to pattern.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model is also not limited to above-mentioned citing; those skilled in the art; in scope of the present utility model, the change made, change add or replace, all should belong to protection domain of the present utility model.
