With the hydraulic boosting operation device used for the dry type constant jointing main clutch, the operation force of the clutch petal is effectively reduced, the labor intensity of a driver is improved and the operational comfortableness is improved.
Description
Technical field
The utility model belongs to engineering machinery field, relates to a kind of hydraulic servo system, relates in particular to a kind of hydraulic servo system that dry type often engages main clutch that is used for.
Background technique
At present, on the tracked construction equipment that China produces, the dry type that is disposed often engages main clutch and adopts the mechanical type operation mechanism of pedal more, and its advantage is simple in structure, and friction factor is high; Shortcoming is that transmitting torque is big, handles effort, brings fatigue to the driver easily.Therefore, the auxiliary power assisting device of being badly in need of a kind of advanced technology reduces driver's labor intensity, improves handling comfort, thereby further promotes production operation efficiency, and then for energy-saving and cost-reducing, improve business efficiency and contribute.
The model utility content
The purpose of the utility model be to provide a kind of simple in structure, reliability is high, the operation comfortable labour-saving be used for the hydraulic servo system that dry type often engages main clutch.
The technological scheme of the utility model is: be used for the hydraulic servo system that dry type often engages main clutch, comprise: booster bearing, hydraulic booster, power-assisted rocking arm and roller; The booster bearing is fixed on the crossbeam of vehicle frame through the bolt level; Hydraulic booster is fixed on the booster bearing through the bolt level, and the bottom of power-assisted rocking arm and booster bearing are hinged, and the top and the adjusting screw rod of power-assisted rocking arm are hinged; The small rod of adjusting screw rod and rocking arm is hinged; rocking arm is hinged through small rod and pull bar, and pull bar is hinged through small rod and clutch pedal, and rocking arm, clutch pedal are fixed on the console through key, locating stud respectively.
Roller in the piston rod of hydraulic booster and the power-assisted rocking arm groove is hinged.
The push rod center line of hydraulic booster and the bulb centerline collineation of clutch release fork and in same plane; Clutch release fork often engages main clutch with dry type and connects through spline, locating stud, and dry type often engages main clutch and engine output shaft links.
The utility model can produce following good effect: often engage in the engineering machinery dry type and realized hydraulic booster on the main clutch; Reduced the clutch pedal steering force effectively; Improve driver's labor intensity, improved handling comfort, promoted production operation efficiency; And then also made bigger contribution for energy-saving and cost-reducing, raising business efficiency, also make hydraulics obtain further popularization and application simultaneously in engineering machinery field.
Description of drawings
Fig. 1 is used for the structural representation that dry type often engages the hydraulic servo system of main clutch for the utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Like accompanying drawing 1, shown in 2, be used for hydraulic servo system that dry type often engages main clutch and mainly contain booster bearing 4, hydraulic booster 5, power-assisted rocking arm 6 and roller 12 and form.Booster bearing 4 is fixed on the crossbeam of vehicle frame 3 through the bolt level; Hydraulic booster 5 is fixed on the booster bearing 4 through the bolt level, and the bottom of power-assisted rocking arm 6 and booster bearing 4 are hinged, and the top of power-assisted rocking arm 6 and adjusting screw rod 7 are hinged; Adjusting screw rod 7 is hinged with the small rod of rocking arm 8; rocking arm 8 is hinged through small rod and pull bar 11, and pull bar 11 is hinged through small rod and clutch pedal 9, and rocking arm 8, clutch pedal 9 are fixed on the console 10 through key, locating stud respectively.
When the driver stepped on down clutch pedal 9, pedaling force was opened hydraulic booster 5 through pull bar 11, rocking arm 8, adjusting screw rod 7, power-assisted rocking arm 6; Hydraulic booster 5 push rods make clutch release fork 2 swings under the effect of hydraulic coupling; And then stir the sliding sleeve that dry type often engages main clutch 1, the release bearing that makes dry type often engage main clutch 1 moves, and often engages the pressure on main clutch 1 driven disc thereby eliminate dry type; Make dry type often engage main clutch 1 and be in separated state rapidly; The driver just can handle the gearbox shift rod like a cork and shift gears, and reaches hydraulic booster, handles comfortable labour-saving target.
The power of stepping on down clutch pedal 9 equals to overcome the spring force of hydraulic booster 5 pressure springs, selects the rated pressure of oil hydraulic pump through this set pressure; Pump delivery, determined to make clutch can satisfy stable starting simultaneously, separate rapidly, thoroughly, engage soft, smooth-going.Two parameters can be carried out type selecting to the hydraulic booster pump in view of the above.
When hydraulic pressure was malfunctioning, this hydraulic control becomes manual machine to be handled, and still can keep maneuverability.Specific operation process is following: when the driver steps on down clutch pedal 9 hydraulic pressure when malfunctioning; Must strengthen pedaling force this moment; The piston that promotes hydraulic booster 5 overcomes the spring force of hydraulic booster 5 pressure springs, directly promotes hydraulic booster 5 and makes clutch release fork 2 swings, and then stir the sliding sleeve that dry type often engages main clutch 1; The release bearing that makes dry type often engage main clutch 1 moves; Thereby eliminate dry type and often engage the pressure on main clutch 1 driven disc, make dry type often engage main clutch 1 and be in separated state rapidly, the driver just can handle the gearbox shift rod and shift gears.
The stack that is in series of above-mentioned implementation methods, the steering hydraulic force aid system that is equally applicable to itself and crawler industry bulldozer is used.This kind situation can be used power assistance pump for steering and satisfied steering hydraulic power-assisted and clutch hydraulic pressure power-assisted simultaneously.
