Abstract
The utility model relates to an engineering machine, which aims at providing a minitype loader suitable for the small operation station. The loader includes a bucket, an oil pressure lifting and overturning system, a vehicle frame and a driving system fixed on the vehicle frame. The driving system includes an engine, a clutch, a gear-box, a transfer-case, transmission shafts, a front bridge and a rear bridge. The gear-box and the transfer-case in the driving system are separately arranged, and are connected through a transmission shaft. The transfer-case is arranged between the front bridge and the rear bridge, and is respectively connected with the front bridge and the rear bridge through transmission shafts. The minitype loader of the utility model has the advantages that the structure is simple, the vehicle frame is compact, and the array of the steering part is rational.
Description
Technical field
The utility model relates to a kind of engineering machinery, the small sized loader that especially a kind of little operation place is suitable for.
Background technology
At present the drive system of small sized loader all adopts the structure of baby tractor or its remodeling, and the drive system of baby tractor is speed change and drive the structure that is connected as a single entity normally, and its speed change complex structure is handled inconvenience, the maintenance rate height; And the drive system of remodeling also usually performance be two types: the one, propons drives rear-axle steering; The 2nd, propons turns to rear bridge driven.The former shortcoming is: when the scraper bowl resistance of meeting in the shovel operation during greater than the driving force of front-wheel, front-wheel skids easily, thus the tractive force of reduction system; And the latter's shortcoming is: structure design is unreasonable, because the motor fuselage will uprightly be arranged on the afterbody of vehicle body, causes whole vehicle body long, turn to not nimble, and its manual control gear is in the centre below the seat, with hydraulic control lever from also far away, be unfavorable for handling.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of little operation place small sized loader that is applicable to is provided, and it is simple in structure, and vehicle body is small and exquisite, and operating station is arranged rationally.
In order to overcome the above problems, the utility model is to be achieved through the following technical solutions:
A kind of small sized loader, comprise scraper bowl, oil pressure lifting overturn system, vehicle frame and the drive system that is fixed on the vehicle frame, drive system comprises motor, clutch, gearbox, transfer case, power transmission shaft, propons and back axle, gearbox and transfer case in the described drive system are provided with separately, between be provided with power transmission shaft and link to each other; Described transfer case is between propons and the back axle, links to each other respectively with back axle with propons by power transmission shaft.
As further improvement of the utility model, the motor in the described drive system is arranged on the afterbody of vehicle frame, and motor is provided with belt pulley; The gearbox clutch of ining succession, an end of clutch also is provided with belt pulley, has belt to link to each other between two belt pulleys.
As further improvement of the utility model, described motor is the afterbody that is horizontally installed on vehicle frame; The position of two belt pulleys is behind car.
The operating principle of the drive system of the utility model small sized loader is: motor rotates simultaneously by the belt pulley that belt pulley drives on the clutch, the clutch gearbox of ining succession, gearbox is sent to power by power transmission shaft through the back of slowing down and does further allotment in the transfer case, by power transmission shaft deployed power is sent to respectively on propons and the back axle again, realizes advancing, retreat and turning to of vehicle body.
Compared with prior art, the beneficial effects of the utility model are:
(1) changed the variable speed drives conjoined structure of original heaviness,, linked to each other with the front and back bridge respectively again, made structure become simply because transfer case and gearbox are provided with separately, the maintenance rate reduction, and increased driving force.
(2) motor is horizontally installed on the tailstock, by belt pulley transmission power, makes the short and small exquisiteness of vehicle body, turns to more nimblely, and operating station is arranged and also is tending towards reasonable.
Description of drawings
Fig. 1 is the structural representation of the utility model small sized loader.
Fig. 2 is the structural representation of the drive system of the utility model small sized loader.
Among the figure, 1 scraper bowl, 2 oil pressure lifting overturn systems, 3 vehicle frames, 4 motors, 5 belt pulleys, 6 belts, 7 clutches, 8 gearboxes, 9 transfer cases, 10 propons, 11 back axles, 12 power transmission shafts.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As Fig. 1 and Fig. 2, a kind of small sized loader of this specific embodiment comprises scraper bowl 1, oil pressure lifting overturn system 2, vehicle frame 3 and the drive system that is fixed on the vehicle frame 3, drive system comprises motor 4, clutch 7, gearbox 8, transfer case 9, propons 10, back axle 11 and power transmission shaft 12, gearbox 8 in the described drive system and transfer case 9 are independent settings, between be provided with power transmission shaft 12 and link to each other; Described transfer case 9 is between propons 10 and the back axle 11, links to each other respectively with back axle 11 with propons 10 by power transmission shaft 12; Motor 4 in the described drive system is horizontally installed on the afterbody of vehicle frame 3, and a belt pulley 5 is arranged on the motor 4; 8 of the gearboxes clutch 7 of ining succession, an end of clutch 7 also has a belt pulley 5 position correspondences, and the position of two belt pulleys 5 has belt 6 to link to each other all towards the rear portion of car between the belt pulley 5.
The course of work of drive system is seen Fig. 2, motor 4 rotation at a high speed, belt pulley 5 on it rotates simultaneously by the belt pulley 5 that belt 6 drives on the clutch 7, clutch 7 gearbox 8 of ining succession, gearbox 8 is sent to power by power transmission shaft 12 through the back of slowing down and does further allotment in the transfer case 9, deployed power then is sent to respectively on propons 10 and the back axle 11 by power transmission shaft 12 again, realizes advancing, retreat and turning to of vehicle.
At last, it is also noted that what more than enumerate only is a specific embodiment of the present utility model.Obviously, the utility model can also have many distortion, and all distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
