Abstract
The utility model discloses a double-bridge wheel type steering and double-bridge driving loader, and relates to an engineering machine, and in particular to a small loader suitable for cave ore, road clearing sites and small operating sites. The loader comprises a bucket, a hydraulic lifting turnover system, a frame, an engine, a clutch, a gearbox, a transmission shaft, steering driving bridges and a steering system. The loader is mainly technically characterized in that: each of the front and rear steering driving bridges in the steering system has a wheel type steering structure, namely a gear pump, a reverser, a redirector, a steering cylinder and each steering driving bridge are sequentially connected; the steering cylinder is arranged between each steering driving bridge and the frame; and steering is controlled by stretching of the steering cylinders. The loader has the advantages that: the conventional hinged, front bridge wheel type steering or rear bridge wheel type steering structure is changed; and because wheel type steering is adopted in the front and rear driving bridges, the operating space is greatly reduced, and the operating time is shortened.
Description
Technical field
The utility model relates to a kind of engineering machinery, especially a kind of suitable grotto ore deposit, the small sized loader that highway is cleared out a gathering place, the operation place is little.
Background technology
The steering of small sized loader all adopts hinged, wheeled, the back axle wheeled construction of propons at present, and its turning radius is big.When shovel fortune is loaded, run into the little or specific environment in place and can not disposablely accomplish, before and after repeating, falling back produces operation procedure complicacy, time length, inefficiency, deficiency in economic performance.
Summary of the invention
The utility model provides a kind of and is applicable to that grotto ore deposit, highway are cleared out a gathering place, the operation place is little, a kind of doube bridge of specific environment wheeledly turns to, doube bridge drives loader.
The utility model is realized through following technical scheme: wheeled the turning to doube bridge of a kind of doube bridge drives loader, comprises scraper bowl, the hydraulic lifting overturn system; Vehicle frame, motor, clutch; Gearbox, power transmission shaft, steering and driving axle; Steering, its major technique characteristic be in the said steering before and after steering and driving axle wheeled steering structure all is set, promptly connect commutator, commutator and connect steering gear, steering gear and connect and turn to oil cylinder, turn to oil cylinder to connect steering and driving axle by gear pump; Be provided with between steering and driving axle and the vehicle frame and turn to oil cylinder, turn to by turning to oil cylinder to stretch to control; With turning to oil cylinder to connect vehicle frame and steering and driving axle, gear pump turns to the oil cylinder tail end to connect vehicle frame with pivot pin through the fluid-pressure transmission steering gear, and the other end connects steering and driving axle with the ball pin.
As the further improvement of the utility model, said doube bridge is wheeled to turn to the Drag link in the yarn system to be replaced by oil cylinder, and the oil cylinder tail end connects vehicle frame with pivot pin, and the other end connects steeraxle with the ball pin, and the front and back steering structure is similar.
As the further improvement of the utility model, said shovel arm column is improved central frame beam is set by original complete machine body front end that is provided with, driver's cabin move into the shovel arm down in, similar slippage car.
The wheeled operating principle that drives the yarn system that turns to of the utility model doube bridge is: motor turns to oil cylinder through gear pump fluid-pressure transmission reversal valve by reversal valve control, reaches the operation required function.Compared with prior art, the useful efficient of the utility model is: changed original hinged, propons is wheeled turns to or the wheeled steering structure of back axle, adopted wheeled turning to because front and back bridge drive axle is complete, dwindled working space greatly, shortened the activity duration.Shovel arm column is provided with central frame beam, and similar slippage car driver's cabin design makes the short and small exquisiteness of vehicle body, turns to more dexterously, and operates looking away.
Description of drawings:
Fig. 1 is the wheeled structural representation that drives loader that turns to of the utility model doube bridge;
Fig. 2 is the wheeled structural representation that turns to the steering that drives loader of the utility model doube bridge.
The specific embodiment:
Among the figure, steering and driving axle, 9-gear pump, 10-commutator, 11-steering gear, 12-turn to oil cylinder, 13-tire before and after 1-scraper bowl, 2-hydraulic lifting overturn system, 3-vehicle frame, 4-motor, 5-clutch, 6-gearbox, 7-power transmission shaft, the 8-.
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:
The wheeled loader of a kind of doube bridge like Fig. 1 and the woody specific embodiment of Fig. 2 comprises scraper bowl 1, and hydraulic lifting upset yarn system 2 usefulness pivot pins connect on the vehicle frame 3; Motor 4, clutch 5 and gearbox 6 are arranged on the vehicle frame 3 in order; Power transmission shaft 7 connects gearbox 6 and drive axle 8; The front and back steering and driving axle is provided with vehicle frame 3 front and back, fixes with fixing the connection with pivot pin of screw respectively; Turn to oil cylinder 12 1 ends to connect vehicle frame 3, the other end connects steering and driving axle 8; The steering structure by gear pump 9, commutator 10, steering gear 11, turn to oil cylinder 12, steering and driving axle 8 to connect to form successively.
At last; It is also noted that; What more than enumerate only is a specific embodiment of the utility model, obviously, and all right many modification of the utility model; 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 belong to the protection domain of the utility model.
