Abstract
The utility model relates to the field of engineering machinery, in particular to a rear-wheel steering forklift loader with a driving device, which comprises a steering wheel, a hydraulic steering system connected with the steering wheel and a steering driving mechanism arranged on the rear side of a vehicle frame. A front vehicle frame and a rear vehicle frame are hinged through an upper hinge pin and a lower hinge pin. The hydraulic system comprises a hydraulic oil tank, a hydraulic oil pump, a hydraulic torque converter, an oil cylinder and an oil pipe. The hydraulic oil tank and the hydraulic torque converter are communicated though the oil pipe, the oil cylinder is communicated with the hydraulic torque converter through the hydraulic oil pump, and the steering driving mechanism comprises a rear steering axle, an upper swing frame, a lower swing frame and a rear steering oil cylinder communicated with a steering axle. Two ends of the rear steering axle are respectively connected with a left rear wheel and a right rear wheel, one ends of the upper swing frame and the lower swing frame are connected with the rear vehicle frame, and the other ends of the upper swing frame and the lower swing frame are connected with the rear steering axle. The forklift loader not only improves work efficiency, but also is reasonable in structure, good in work reliability and applied to driving in mining areas or on a soft road surface.
Description
Technical field
The utility model relates to engineering machinery field, and particularly a kind of harbour that is applicable to is carried the forklift truck that the rear-axle steering band that goes in rough stone block field, stone material mining area drives.
Background technology
Loading attachment uses in the engineering field very extensively; Existing fork assembling device all is to turn to driving before having only; Carrying under the heavy situation, cause rollover during walking easily, particularly under the bad situation of road conditions; Sinkings of subsiding appears in the trailing wheel of fork assembling device easily, more can not be in the mining area perhaps soft road traveling.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency, provide a kind of simple and reasonable, functional reliability good, have the forklift truck that the rear-axle steering band drives.
For realizing above-mentioned purpose; The technical solution of the utility model is: the forklift truck that a kind of rear-axle steering band drives; Comprise bearing circle on the operator's compartment, with bearing circle bonded assembly hydraulic efficiency pressure system and be arranged at the driver train that turns to of vehicle frame rear side; Said vehicle frame comprises front vehicle frame and back vehicle frame, and said front vehicle frame and back vehicle frame are through swivel pin is hinged up and down, and said hydraulic efficiency pressure system comprises hydraulic reservoir, hydraulic oil pump, hydraulic torque converter, hydraulic ram and oil pipe; Be connected through oil pipe between hydraulic reservoir and the hydraulic torque converter; Hydraulic ram is connected with hydraulic torque converter through hydraulic oil pump, saidly turn to driver train to comprise the back steeraxle, go up swing span, the lower swing frame and and the back steeraxle be connected after turn to oil cylinder, the two ends of said back steeraxle are connected with left and right sides trailing wheel respectively; A said end of going up swing span, lower swing frame is connected in the back vehicle frame, and the other end is connected on the steeraxle of back.
Said bearing circle is connected with hydraulic torque converter and after turning to driver train to promote, turns to oil cylinder.
Said hydraulic torque converter is two turbine hydraulic torque converters.
Through adopting above-mentioned technical scheme; The beneficial effect of the utility model is: the hydraulic pressure rear-axle steering driver train of the utility model has not only improved the work efficiency of forklift truck; And simple and reasonable, functional reliability is good, is applicable in the mining area or soft road traveling.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1; The forklift truck that a kind of rear-axle steering band of the utility model drives; Comprise bearing circle 1 on the operator's compartment, with bearing circle 1 bonded assembly hydraulic efficiency pressure system and be arranged at the driver train that turns to of vehicle frame 2 rear sides; Said vehicle frame 2 comprises front vehicle frame 21 and back vehicle frame 22, and said front vehicle frame 21 and back vehicle frame 22 are through swivel pin 23 is hinged up and down, and said hydraulic efficiency pressure system comprises hydraulic reservoir 3; Hydraulic oil pump 4, two turbine hydraulic torque converter 5, hydraulic ram 6 and oil pipe; Be connected through oil pipe between hydraulic reservoir 3 and the two turbine hydraulic torque converters 5, hydraulic ram 6 is connected with pair turbine hydraulic torque converters 5 through hydraulic oil pump 4, and hydraulic oil pump 4 is used to supply with whole hydraulic efficiency pressure system provides the energy; Saidly turn to driver train to comprise back steeraxle 7, go up swing span 9, lower swing frame 10 and and back steeraxle 7 be connected after turn to oil cylinder 8; Said bearing circle 1 is connected with hydraulic torque converter 5 and turns to oil cylinder 8 through after turning to driver train to promote; The two ends of said back steeraxle 7 are connected with left rear wheel 71 and off hind wheel 72 respectively; A said end of going up swing span 9, lower swing frame 10 is connected in back vehicle frame 21; The other end is connected on the steeraxle 7 of back, is used to drive the left rear wheel 71 on the steeraxle 7 of back, the left steering and the right steering of off hind wheel 72.
Above-described, be merely a preferred embodiment of the utility model, can not limit the scope that this practicality is implemented, every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
