A vehicle frame and a road roller

By designing detachable counterweights and counterweight cavities on the roller frame, the center of gravity position can be flexibly adjusted, solving the compaction capacity and stability problems of the roller under different working conditions and improving its performance on steep slopes and sandy terrain.

AI Technical Summary

Technical Problem

The fixed weight distribution ratio of the front and rear wheels of existing road rollers makes it difficult to climb steep slopes and sandy areas, and they are prone to slipping, failing to meet the compaction requirements of various working conditions.

Method used

Design a frame with detachable counterweights and counterweight chambers, allowing the counterweights to be flexibly adjusted along the length of the frame, and achieving flexible adjustment of the center of gravity position by transferring them between the first and second counterweight chambers.

Benefits of technology

It improves the flexibility and compaction capacity of the road roller under different working conditions, effectively copes with special working conditions such as slopes and sandy areas, and maintains the normal operation of the road roller.

Abstract

The application provides a vehicle frame and a road roller, wherein the vehicle frame comprises a body and a counterweight assembly, the body has a first counterweight cavity and a second counterweight cavity, the first counterweight cavity and the second counterweight cavity are arranged at intervals along the length direction of the body; the counterweight assembly comprises a plurality of counterweight blocks, the counterweight blocks are detachably arranged in the first counterweight cavity or the second counterweight cavity; the number of the counterweight blocks is N, the total number of the counterweight blocks that can be accommodated by the first counterweight cavity and the second counterweight cavity is M, and M>N, so that the counterweight blocks can be transferred between the first counterweight cavity and the second counterweight cavity; under the arrangement mode, the road roller applied with the vehicle frame can flexibly adjust the front and back positions of the gravity center, thereby ensuring the compaction capacity of the road roller and enabling the road roller to well cope with special working conditions such as slopes and sandy land; and since the weight of a single counterweight block is small, the single counterweight block is more convenient to transfer between the first counterweight cavity and the second counterweight cavity.
