Abstract

The invention discloses a special tool for adjusting an air bag height valve of a cab and a method. The special tool comprises fixed cushion blocks and a positioning pin, wherein the two fixed cushion blocks are symmetrically arranged between a turnover arm on a vehicle body chassis and a suspension lower limiting block at an interval, and the positioning pin is used for limiting the height valve and a height valve swing rod. According to the special tool, in an airless state, the air bag height valve is adjusted through the fixed cushion blocks and the positioning pin, the height is not changed after inflation, the loading efficiency is improved, and use is convenient.

Description

technical field [0001] The invention belongs to the technical field of automobile equipment, and in particular relates to a special tool and method for adjusting the height valve of an air bag in a driver's cab. Background technique [0002] Some existing trucks are equipped with cab suspensions with airbag structures. The airbag suspensions rely on the air in the airbags as an elastic element. The difference in frame height inflates and deflates the airbags, keeping the cab as level as possible and reducing vibration. [0003] During the production process of the vehicle, when the cab is just installed on the frame, due to manufacturing errors and other factors, and because the center of gravity of the cab is not necessarily in the middle of the vehicle width direction, after the air bag and the height valve are ventilated, the cab may be Askew. At this time, it is necessary to adjust the cab to a horizontal state through the adjustment device on the height valve and its ...
