Abstract
The utility model discloses a rear hinge joint steering mechanism of a loader and relates to a steering mechanism system in engineering machinery, specifically to a system of the rear hinge joint steering mechanism of the loader. The rear hinge joint steering mechanism is characterized in that an engine transmits power to a gear pump and thus transmits power to a priority valve hydraulically; the priority valve is connected with a multi-way valve and a steering gear; through oil pipes, the steering gear is connected with two steering cylinders disposed on the left and right sides of a rear axle frame respectively; one end of each steering cylinder is connected with a front frame through an axle pin and the other end of the steering cylinder is connected with the rear axle frame through an axle pin; the front frame is connected with the rear axle frame through an upper axle pin and a lower axle pin; and a rear axle frame drive axle is driven by the steering cylinders to realize steering. The rear hinge joint steering mechanism changes a hinge joint type and front axle wheel type steering structure or a rear axle wheel type steering structure in a conventional structure, realizes independent steering of the rear axle frame and the rear drive axle, improves safety stability of the whole loader during operations of loading and lifting, and improves drive capability.
Description
Technical field
The utility model relates to the steering hardware system of construction machinery and equipment, in particular, relates to a kind of system of back hinged steering mechanism of loader.
Background technology
The steering hardware that present small-sized dress is cut out machine all adopts propons articulation steering formula or rear wheel steer, and vehicle body poor stability when its propons articulated steering loads operation, rear wheel steer are that propons drives, and tractive force is little, is not suitable for height and unloads operation.And make that operation is dangerous, time length, inefficiency, deficiency in economic performance.
Summary of the invention
The utility model provides a kind of vehicle body that needs of high unloading operation that is applicable to stablize, and the little a kind of back hinged steering mechanism in strong, the suitable operation place of driving power, and simple in structure, vehicle body is stable, flexible operation.
The utility model is to realize through following technical scheme: a kind of back hinged steering mechanism of loader; The drive system that comprises hydraulic efficiency pressure system, front vehicle frame, rear axle stand, forms by driving engine, tor-con, change speed gear box, transmission shaft, front and back drive axle; Its major technique characteristic is to transfer to gear type pump through engine power, and fluid-pressure transmission connects multiway valve and deflector to pressure-gradient control valve respectively by pressure-gradient control valve; Deflector connects respectively with oil pipe that two of two sides turn to oil cylinder about rear axle stand; Turn to oil cylinder one end to connect front vehicle frame with pivot pin, the other end connects rear axle stand with pivot pin, and front vehicle frame and rear axle stand are connected with two fulcrum pins up and down; By turning to hydraulic oil cylinder driving, make the rear axle stand drive axle realize turning to;
Said front vehicle frame, loader mechanism, operator's compartment, driving engine, change speed gear box, tor-con, fuel tank are integrally formed, and design is changed to make about rear axle stand through hinge point and turned to, and complete machine stresses to be consistent forever when loading any the turning to of operation.
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; Existing in front vehicle frame (comprising that loader mechanism, operator's compartment, driving engine, change speed gear box, tor-con, fuel tank are integrally formed); Turn to separately by rear axle stand and rear driving axle, solved the security and stability that in the middle of loading lifting operation, has improved car load greatly, also strengthened power-handling capability.
Description of drawings
Fig. 1 is the overall schematic of hinged steering mechanism dress sanction machine behind the utility model;
Fig. 2 is the structural representation of hinged steering mechanism behind the utility model.
The specific embodiment
Among the figure, counterweight behind bridgework, 14-rear driving axle, 15-driving engine, the 16-behind 1-front driving axle, 2-pressure-gradient control valve, 3-front vehicle frame, 4-multiway valve, 5-change speed gear box, 6-deflector, 7-fuel tank, 8-operator's compartment, 9-direction oil cylinder, 10-tor-con, 11-transmission shaft, 12-rear axle stand, the 13-.
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:
A kind of back hinged steering mechanism like Fig. 1 and Fig. 2 specific embodiment; Comprise front vehicle frame 3, have front driving axle 1, fuel tank 7, operator's compartment 8, tor-con 10, change speed gear box 5, driving engine 15, back counterweight 16 to be installed together above and form an integral body that back bridgework 13, rear driving axle 14, another back counterweight are installed together; Drive axle before and after driving engine 15 drives through transmission shaft through tor-con 10 and change speed gear box 5; Driving engine is through gear type pump fluid-pressure transmission to pressure-gradient control valve 2, and pressure-gradient control valve 2 one tunnel connects multiway valve 4, another road to deflector 6; By deflector 6 control direction oil cylinders 9; 9 one of direction oil cylinders connect 3, one of front vehicle frame and connect 12, two direction oil cylinders 9 of rear axle stand and stretch inside and outside respectively and control direction.
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.
Claims (2)
1. the back hinged steering mechanism of a loader comprises hydraulic efficiency pressure system, front vehicle frame, rear axle stand, by the drive system that driving engine, tor-con, change speed gear box, transmission shaft, front and back drive axle are formed, and it is characterized in that transferring to gear type pump through engine power; Fluid-pressure transmission is to pressure-gradient control valve; Connect multiway valve and deflector respectively by pressure-gradient control valve, deflector connects respectively with oil pipe that two of two sides turn to oil cylinder about rear axle stand, turns to oil cylinder one end to connect front vehicle frame with pivot pin; The other end connects rear axle stand with pivot pin; Front vehicle frame and rear axle stand are connected with two fulcrum pins up and down, by turning to hydraulic oil cylinder driving, the realization of rear axle stand drive axle are turned to.
2. the back hinged steering mechanism of a kind of loader as claimed in claim 1; It is characterized in that said front vehicle frame, loader mechanism, operator's compartment, driving engine, change speed gear box, tor-con, fuel tank are integrally formed, design is changed to make about rear axle stand through hinge point and is turned to.
