Cab turnover mechanical cylinder

Abstract

The invention discloses a cab turnover mechanical cylinder, and belongs to the technical field of automobile accessories. The invention aims to design a cab overturning mechanical cylinder for liftingand overturning a cab in a mechanical form. A cab end shaft sleeve is fixedly installed at one end of a rod, the other end of the rod is inserted into a cylinder barrel, the rod is composed of an upper inserting rod and a lower base, the outer diameter of the lower base is larger than that of the upper inserting rod to form a clamping table, and an end cover is installed at the top end of the cylinder barrel and arranged outside the upper inserting rod in a sleeving mode; the interior of the cylinder barrel is divided into a rod buffer cavity and a screw rod cavity through a partition plate,and a buffer gap is reserved between the lower base and the partition plate. A screw rod is inserted into the screw rod cavity from the bottom end of the cylinder barrel, a gear sleeve with gear sleeve inner teeth is fixedly installed at the bottom end of the cylinder barrel, and the gear sleeve inner teeth are matched with screw rod outer teeth of the screw rod. The cab turnover mechanical cylinder is simple in structure and convenient to operate. Due to the fact that lifting and overturning of the cab are completed through mechanical transmission, the problems caused by insufficient air pressure or oil pressure of an existing air cylinder and an existing hydraulic cylinder are effectively avoided. Pure mechanical transmission can effectively guarantee safety while guaranteeing normal lifting and overturning functions.

Description

Technical field [0001] The invention belongs to the technical field of auto parts. Background technique [0002] The cab flip technology is widely used in existing large freight vehicles. Generally, cylinders and hydraulic cylinders are used for support. The air pressure or hydraulic pressure is adjusted to achieve the expansion and contraction between the cylinder body and the piston rod, thereby lifting the cab. L flip. With this type of lifting and turning cylinder, once there is gas or liquid leakage, the lifting and turning of the cab cannot be achieved. In addition, if gas or liquid leakage occurs in the lifting form, it is extremely likely to cause danger. Summary of the invention [0003] The purpose of the present invention is to design a cab turning mechanical cylinder that lifts and turns the cab in a mechanical manner. [0004] One end of the rod of the present invention is fixedly installed with a cab end bushing, and the other end is inserted into the cylinder. The r...
