Conveniently opened and closed lubricating oil filling door for suspension

Abstract

The invention discloses a conveniently opened and closed lubricating oil filling door for a suspension. According to the technical scheme, the lubricating oil filling door comprises a luggage compartment baffle, wherein a door hole is formed in the luggage compartment baffle; a filling door frame is arranged in the door hole; a flexible rubber strip is arranged at the periphery of the filling door frame; a filling door plate is arranged on the lower part of the filling door frame through a single-shaft hinge; a fixing nut is arranged on the upper part of the filling door frame; and a bolt hole and a fastening bolt matched with the fixing nut are arranged on the top of the filling door plate. The lubricating oil filling door has the advantages that the lubricating oil filling door is simple in structure, low in machining and manufacturing cost and convenient to operate; the door can be conveniently opened so as to fill lubricating oil on the premise that the original structure and parts are not destroyed; when the lubricating oil is not filled, the door is tightly closed, so that a phenomenon that dust and muddy water outside a vehicle enter the lubricating oil filling door or a luggage compartment can be avoided; simultaneously, the appearance of the integral structure is attractive; and the lubricating oil filling door is practical.

Description

technical field [0001] The invention relates to a suspension lubricating oil filling door which is convenient to open and close, in particular to a lubricating oil filling door of a suspension system in a chassis assembly of a large bus. Background technique [0002] With the development of the society, the progress of the economy, and the continuous improvement of people's living standards, traveling is the choice of most people, and buses often become the most common means of transportation. As we all know, a bus is composed of tens of millions of parts, including electronic parts, mechanical parts, and plastic parts, but most of the bearing parts are composed of mechanical parts. Therefore, ensuring reliable lubrication between mechanical parts has become an issue that affects the use of buses. Key points for safety and longevity. [0003] According to the working characteristics of the bus, on average every 30,000 kilometers or every month, it is necessary to add lubric...

Problems solved by technology

However, due to self-tapping fixing, it is easy to loosen. Mud and water often enter the luggage compartment from the loose space, which not only wets the luggage in the luggage compartment, but also makes the appearance unsightly. The self-tapping screw cannot be fastened after a few times of use, so the convenience and reliability of the filling door cannot be guaranteed.
