Abstract

The invention provides an integrated installation type rim lubricating device with an air source system. The integrated installation type rim lubricating device comprises an electronic control system(1), an air source system (2), a pneumatic actuator (3), a grease tank (4) and a base plate (5). According to the integrated installation type rim lubricating device, the integrated installation design is adopted, all components except for a spraying nozzle and a rubber hose are arranged together to form an integrated unit to be installed into a driver room of a rail traffic vehicle. The form of the integrated unit facilitates device installation and maintenance, connectors are simple, the occupied space is small, the structure is compact, too many pipes for transmitting compression air is notneeded, and the pressure loss is small. A pull rod type air capacitor is used for storing the compression air, welding seams are avoided, all related parts can be directly installed at the preservedconnector of the air capacitor, and the structure is simple. The spraying nozzle installed on a bogie is simple in structure, mechanical motion does not exist insides, electric elements are not provided, the working is reliable under the working condition of impact vibration, and the efficiency cannot be lost.

Description

technical field [0001] The invention relates to the field of lubricating wheel rims of rail transit vehicles in the railway industry, in particular to an integrated installation type wheel rim lubricating device with its own air source system. Background technique [0002] When the rail transit vehicle is running, due to the curve or serpentine swing, the wheel rim will contact and rub against the gauge angle, forming running resistance, and causing wear on the wheel rim and rail at the same time. Wheel rim wear and rail side wear are one of the main types of damage to wheels and rails on curves. The problem of wheel rim and rail side wear has always been an important factor affecting the life of wheels and rails. The wheel flange lubrication device can provide lubrication between the wheel flange and the rail, which can effectively improve the friction performance between the wheel and rail, reduce the noise and power loss of the wheel and rail, slow down the wear speed of ...
