Road roller frame hinged structure

Abstract

The invention relates to a road roller frame hinge structure. The seat board of a hinge frame is welded to the rear crossbeam of a rear frame, a spider assembly comprises a spider and a bogie, bearing segments at two ends of the transverse shaft of the spider arranged in the hinge frame are arranged on the seat board and a rear end cover through angular contact bearing, bearing segments at two ends of the vertical shaft of the spider are arranged in bearing holes of the upper hinge arm and the lower hinge arm of a front frame through angular contact bearings, the deflecting plate of the bogie is symmetrically provided with deflecting hinge holes along the central axis of the vertical shaft, a distance L1 between the central axis of the vertical shaft and the central axis of the deflecting hinge holes is 220-260 mm, a center distance L3 between the central axis of the vertical shaft and the central axis of the deflecting hinge holes is 0-25 mm, a distance L2 between the center line of the deflecting plate and the center line of the transverse shaft is 160-216 mm, and the bogie is symmetrically provided with swing blocks along the central axis of the vertical shaft. The road roller frame hinge structure has the characteristics of good compactness, hinge reliability improvement, convenience in maintenance, and low manufacturing cost.

Description

technical field [0001] The invention relates to a hinged structure of a road roller frame and belongs to the technical field of vibratory road roller frames. Background technique [0002] The frame of a vibratory roller is generally composed of a front frame, a rear frame, a counterweight, etc., and the front frame and the rear frame are connected by a hinged frame to ensure that the front and rear frames rotate relatively in the horizontal plane, and at the same time in the vertical plane. It can also swing to a certain extent in order to improve the mobility and adhesion performance of the road roller, and meet the requirements of various types of foundation compaction operations. As a basic carrier, the frame bears various dynamic, static and impact loads, and is generally made into a relatively complex space box structure. The frame occupies 40-60% of the weight of the vibratory roller, accounting for a large proportion of the cost of the whole machine, and The greater ...

Problems solved by technology

However, the rear beam of the front frame must pass through the middle of the hinge frame, which not only limits the size of the rear beam, but also makes the hinge structure complex and takes up a lot of space, especially the axial dimension is relatively long, the manufacturing cost is relatively high, and the commissioning and installation costs In the process of use, the lock nut is easy to loose and cause bearing wear and damage, and maintenance and repair are difficult, especially when the horizontal sleeve is worn, the front frame and rear cross beam need to be replaced, and the maintenance cost is high
