Problems solved by technology

After many impacts for a long time, there is a risk that the piston of the oil cylinder and the connecting pin between the oil cylinder and the vehicle body will fall off, causing the cab to turn out of control, and continue to turn forward and smash the cab. If there are maintenance personnel in front, it is more likely to cause casualties

Abstract

The invention discloses a driving cab rollover protection mechanism. The driving cab rollover protection mechanism comprises a rollover torsion bar; each of two ends of the rollover torsion bar is provided with a suspension lower support and a limiting arm; a limiting block is arranged at a position corresponding to each limiting arm on the corresponding suspension lower support; and when limiting is performed, a bottom surface of each limiting arm is attached to a top plane of the corresponding limiting block. A limiting structure formed by the limiting arms and the limiting blocks is simple in structure, and the center of gravity and the structure of a complete vehicle are not influenced. When limiting is performed, the bottom surface of each limiting arm is attached to the top plane of the corresponding limiting block, so that a high load can be borne, and the problem of limiting structure failure caused by the gravity of a driving cab is solved. The driving cab rollover protection mechanism disclosed by the invention is simple in structure, low in cost and high in enforceability, and is suitable for being popularized in large batches.

Description

technical field [0001] The invention relates to the field of cab overturning mechanisms, in particular to a cab overturning protection mechanism. Background technique [0002] At present, the chassis of commercial vehicles in my country generally adopts a flat cab, and the engine is placed under the cab. In order to ensure the installation and maintainability of the engine, all types of commercial vehicle chassis cabs are equipped with cab turning mechanisms. Among them, light commercial vehicles generally adopt torsion bar turning mechanism, and medium and heavy commercial vehicles generally adopt hydraulic lifting mechanism. The hydraulic lifting mechanism can be divided into two types: floating outside the cylinder and floating inside the cylinder according to the connection between the lifting cylinder and the body. In order to increase the turning angle of the cab and improve the threat performance of the power system, the chassis of Dongfeng Tianlong, Dongfeng Hercul...
