Abstract
The utility model relates to a steering structure for a rear axle. The steering structure comprises a left steering wheel, a right steering wheel and a hydraulic cylinder, wherein the hydraulic cylinder is fixedly arranged on the middle part of the rear axle through a fixing base; the hydraulic cylinder is arranged as a bidirectional hydraulic cylinder; a piston rod at each end is connected with a steering mechanism; the steering mechanism comprises a cleat shaft, a knuckle bearing, a locknut and a ball pin pull rod joint which are connected in turn; the piston rod is connected with one end of the ball pin pull rod joint which is not connected with the locknut; a cleat shaft rotating supporting base on a steering wheel shaft is connected with one end of the cleat shaft which is not connected with the knuckle bearing. The steering structure for the rear axle has the advantages that the steering direction can be conveniently and quickly adjusted, the operation is flexible and labor-saving, the working strength of a driver is effectively reduced and the working efficiency is increased.
Description
Technical field
The utility model relates to a kind of harvester steering rear axle structure, particularly a kind of rear-axle steering structure.
Background technology
At present, the most four-bar linkages that adopt unidirectional oil cylinder effect of wheeled corn machine.Large-scale cropper in the time of farm work, because different soil is different to the adhesion coefficient of machine, particularly soft soil, cornering resistance is larger, when chaufeur carries out farm work for a long time, working strength is large, easily tired.
Utility model content
The purpose of this utility model is to provide one and can convenient and swift adjustment turns to, and the while is flexible, light labour-saving rear-axle steering structure again.
The technical scheme that realizes the utility model object is: the utility model comprises left steering wheel, right steering wheel, hydraulic ram; Described hydraulic ram is fixedly installed on the middle part of axle casing by permanent seat; The two ends of described hydraulic ram are equipped with piston rod, and the piston rod in left side is connected with left-hand control, and the piston rod on right side is connected with right steering mechanism; Described left-hand control comprises the left spindle, oscillating bearing and the ball pin rod head that connect successively, wherein one end of ball pin rod head is connected with oscillating bearing by jam nut, the other end is connected with the piston rod in left side by jam nut, and one end that left spindle is not connected with oscillating bearing is connected with the spindle swivel bearing seat on left steering wheel shaft; Described right steering mechanism comprises the right spindle, oscillating bearing and the ball pin rod head that connect successively, wherein one end of ball pin rod head is connected with oscillating bearing by jam nut, the other end is connected with the piston rod on right side by jam nut, and one end that right spindle is not connected with oscillating bearing is connected with the spindle swivel bearing seat on right steering wheel shaft.
The above permanent seat is connected by bolt and hydraulic ram.
The utlity model has positive effect: (1) the utility model adopts bidirectional hydraulic oil cylinder, turn to easilyer, can alleviate the working strength of chaufeur; (2) the utility model turns to flexibly, can conveniently turn to, and increases work efficiency.
Brief description of the drawings
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
See Fig. 1, the utility model comprises left steering wheel 1, right steering wheel 11, hydraulic ram 8; Described hydraulic ram 8 is fixedly installed on the middle part of axle casing by permanent seat 9; The two ends of described hydraulic ram 8 are equipped with piston rod 7, and the piston rod 7 in left side is connected with left-hand control, and the piston rod 7 on right side is connected with right steering mechanism; Described left-hand control comprises the left spindle 2, oscillating bearing 3 and the ball pin rod head 5 that connect successively, wherein one end of ball pin rod head 5 is connected with oscillating bearing by jam nut 4, the other end is connected with the piston rod 7 in left side by jam nut 6, and one end that left spindle 2 is not connected with oscillating bearing 3 is connected with the spindle swivel bearing seat on left steering wheel shaft; Described right steering mechanism comprises the right spindle 10, oscillating bearing 3 and the ball pin rod head 5 that connect successively, wherein one end of ball pin rod head 5 is connected with oscillating bearing by jam nut 4, the other end is connected with the piston rod 7 on right side by jam nut 6, and one end that right spindle 10 is not connected with oscillating bearing 3 is connected with the spindle swivel bearing seat on right steering wheel shaft.
When work, the piston rod 7 of hydraulic ram is moved to the left, drive the ball pin rod head 5 in left side to be moved to the left, the ball pin rod head 5 in left side drives the oscillating bearing 3 in left side to move to left, the oscillating bearing 3 in left side drives left spindle 2 to rotate around spindle swivel bearing seat, thereby drive the left steering wheel 1 being connected with left spindle 2 to rotate, right oscillating bearing 3 drives right spindle 10 to rotate around spindle swivel bearing seat simultaneously, thereby drive the right steering wheel 11 being connected with right spindle 10 to rotate, realize left steering; Otherwise, realize right steering.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
