Abstract
The utility model discloses a front axle mechanism of a land scraper. The front axle mechanism comprises a left hinge, a left connecting frame, steering pin shafts, a left steering oil cylinder, a bridge, a steering pull rod, a right steering oil cylinder, a right connecting frame and a right hinge, wherein the left connecting frame is connected with the left hinge through a pin shaft; the left steering oil cylinder and the steering pull rod are arranged on the steering pin shaft positioned on the left hinge; the bridge is connected with the left connecting frame and the right connecting frame through pin shafts; the right connecting frame is connected with the right hinge through a pin shaft; and the right steering oil cylinder and the steering pull rod are arranged on the steering pin shaft positioned on the right hinge. The front axle mechanism has high generality, and can be applied to a medium-sized land scraper and a large-sized land scraper, so that the design cost and the production and manufacturing costs can be saved greatly; the front axle mechanism is convenient for after-sale service; and the bridge has high intensity and high stability, and can meet the using requirements under severe working conditions.
Description
Technical field
The utility model relates to road grader, especially the preceding bridge mechanism of road grader.
Background technology
At present domestic road grader is mainly hinged by left and right sides steering swivel, the left and right sides, steering track rod, crane span structure, about turn to oil cylinder to form, oil cylinder and steering track rod are divided in left and right sides pivotally attached diverse location, and crane span structure is box-like mechanism, though this structure has also satisfied the requirement that turns to, the commonality of this kind structure and extendability are not strong.
Summary of the invention
The purpose of this utility model provides the preceding bridge mechanism of a kind of road grader, solves the not strong defective of former mechanism commonality and extendability.
The purpose of this utility model realizes as follows: this mechanism comprises hinged, the left link span in a left side, turns to bearing pin, left steering oil cylinder, crane span structure, steering track rod, right steering oil cylinder, right link span and right hinged, left side link span is hingedly connected together by a bearing pin and a left side, left steering oil cylinder and steering track rod are installed in and are positioned at a left side turning on the bearing pin on hinged, and crane span structure links together by bearing pin and left link span, right link span; Right link span is hingedly connected together by bearing pin and the right side, and right steering oil cylinder and steering track rod are installed in and are positioned at the right side turning on the bearing pin on hinged.King pin and turn to the installation site of oil cylinder to make that rationally steering torque is bigger, and steering angle is increased, this has also reduced the turn radius of car load.
Crane span structure is the frame structure that plate iron is welded, and the big stability of intensity is high.
The utlity model has very strong commonality, not only can be used on the medium-sized road grader, and can use on large-scale road grader, save design cost and manufacturing cost so greatly, and be convenient to past-sale service.Crane span structure intensity is big, and good stability can satisfy the operating needs under the bad working environments.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing, the utility model is hinged 1 by a left side, left link span 2, turn to bearing pin 3, left steering oil cylinder 4, crane span structure 5, steering track rod 6, right steering oil cylinder 7, right link span 8 and right hinged 9 to form.Left side link span 2 links together by a bearing pin and a left side hinged 1, left steering oil cylinder 4 is installed in steering track rod 6 and is positioned at turning on the bearing pin 3 on the left side hinged 1, the frame structure that crane span structure 5 is welded for plate iron, crane span structure 5 links together by bearing pin and left link span 2, right link span 8; Right link span 8 links together with right hinged 9 by bearing pin, and right steering oil cylinder 7 is installed in steering track rod 6 and is positioned at turning on the bearing pin 3 on right hinged 9.
