Now in conjunction with the accompanying drawings the structure of four-wheel loader is described in detail;
By Fig. 1,2, the four-wheel loader has kept the structure of four-wheeled tractor, but has increased loader mechanism, and tipping bucket arm (3) and lifting arm (12) are with pivotal joint; One end of the plunger of dump ram (5) and tipping bucket arm (3) is affixed, and an end of lifting arm (2) and scraper bowl (1) are affixed; The lower end of tipping bucket arm (3) also is connected with scraper bowl (1) with pipe link, and the upper right side of lifting arm (2) is connected with upright arm (4), and hoist cylinder (5) is positioned at the inboard of trailing wheel (16), and the mutual structure of these parts also is identical with existing loader.This loader mechanism relies on upright arm (4) to be fixed on the change speed gear box (15), and the lower end of hoist cylinder (5) is connected with upright arm (4) bottom, and is supported on above the upright arm (4); Lifting tipping bucket handle (21) joins with multiple directional control valve (8), is positioned at bearing circle (22) front, and is contiguous with gear change hand lever (20), this handle (21) control scraper bowl and tipping bucket action.
Between driving engine (9) and change speed gear box (15), set up a displacement case (12), displacement case (12) is fixed on above the chassis (13), displacement case (12) has a casing (30), casing inner gear (31) and (32) engagement, gear (32) is contained on the axle (33), it is spacing with nut that axle head is equipped with belt pulley (26), gear (31) is contained on the axle (33), axle head also is equipped with belt pulley (25), the left end of axle (33) has coupler (35) and Hydraulic Pump (7) and axle upper coupling (36) to join, (referring to Fig. 2), belt pulley (23) on driving engine (9) axle is connected with belt pulley (26) by belt (28), and displacement case (12) is gone up another belt pulley (23) and is connected with belt pulley (26) by belt (28).
Driving engine (9) drives front-wheel (11) and trailing wheel (16) and travels by belt direct drive change speed gear box (15) work, and originally the belt pulley (23) of driving engine (9) is homodromal with belt pulley (24); Acquire after the displacement case (12), because the engagement of gear (31) and (32) just becomes contrarotation, thus six speed change gears of the forward gear of former trac. are converted to 6 gears that advance of loader, one reverses gear and also converts reversing gear of loader to; The conversion of gear is all realized by gear change hand lever (20).
By Fig. 1, between the change speed gear box (15) of former trac. and chassis (13), set up an intermediate box (14), can strengthen the balance of complete machine, intermediate box (14) is affixed with change speed gear box (15) and chassis (13), and intermediate box has also increased the space of operator's compartment; Intermediate box (14) is a body structure, and the length of complete machine is also increased, center of gravity just from trailing wheel (16) to front-wheel (11) move an end distance from, so improved stability.
The fulcrum shaft (29) of brake connecting rod (17) and clutch linkage (39) is through intermediate box (14) and be fixed on above the intermediate box (14), and brake connecting rod (7) joins with brake pedal (19), steps on pedal (19) and just can brake; Pedal of clutch (38) and clutch linkage (39) interlock; Bearing circle (22) transmission is positioned at intermediate box (14) and goes up connecting rod on the direction fulcrum shaft (29) of opposite side, and then drives direction connecting rod (18) and control its direct of travel, and a counterweight (10) is fixed in (13) front portion on the chassis.
By Fig. 3, fuel tank (37) is connected with Hydraulic Pump (7) by oil pipe, passes through coupler (35) again and is connected with displacement case (12), and multiple directional control valve (8) is connected with lifting tipping bucket handle (21).
Bearing circle (22) and gear change hand lever (20) and brake pedal (19) and pedal of clutch (38) are housed in the operator's compartment.
Hydraulic control is identical with the engineering loader basically, just the power of its hydraulic is when providing driving engine (9) work by the gear wheel shaft (33) on the displacement case (12), belt pulley (23) drive pulley (26) is because gear (31) and (32) engagement also rotate axle (33); This axle (33) is connected with the axle (36) of Hydraulic Pump (7) by coupler (35) it is also rotated, and Hydraulic Pump (7) is work just, and axle (36) is affixed, also affixed with axle (34) by coupler (35).
Compared with prior art the four-wheel loading machine has following advantages:
1. between engine and gearbox, set up a displacement case, the loading machine direct of travel can be dragged with former The direction of advance of machine drawing is opposite, and the displacement case is realized the commutation action.
2. between gearbox and chassis, set up an intermediate box, can strengthen the balance of loading machine, also increase The big space of driver's cabin.
3. load and unload simple and easyly, only need 6 hours detachable its loader mechanisms, revert to the tractor use.
4. carrying capacity can reach 0.3m
3, it is 11 seconds that lifting arm promotes fall time, the scraper bowl time of leaning forward was 3 seconds.
5. volume is little, is suitable for narrow place and uses.
6. efficiency of loading height.
7. can advance at utmost speed when unloaded, but ease astern during loading is safe and reliable in the use.
