Plastic steering oil tank assembly

Abstract

The invention discloses a plastic steering oil tank assembly. The assembly comprises a tank cover assembly, a tank body and a filter screen, the tank cover assembly is composed of a tank cover, an oil-gas separation cavity and a sealing gasket, the oil-gas separation cavity is provided with a two-stage oil-gas separation structure of a first-stage separation cavity and a second-stage separation cavity, and the tank body is composed of an upper tank body and a lower tank body; and a filling pipe opening, an oil outlet pipe opening and an oil return pipe opening are reserved in the lower tank body, and the upper tank body and the lower tank body are connected through friction welding; The filter screen is fixed through a bottom clamping groove at the inner side of the lower tank body; and the tank cover assembly is in threaded connection with the upper part of the upper tank body. By adopting the two-stage separation cavity structure, oil liquid is effectively filtered, and the risk of oil leakage and oil seepage is reduced; an oil baffle is arranged on the tank cover and can prevent a large amount of oil from entering an oil storage cavity; and the tank body is provided with a filling port, so that the oil filling convenience is effectively improved. The plastic steering oil tank assembly is simple in structure, excellent in performance and high in manufacturability, and the problems of oil leakage, oil seepage and inconvenient filling of an existing steering oil tank are solved.

Description

technical field [0001] The invention relates to a plastic steering oil tank assembly, which belongs to the technical field of auto parts. Background technique [0002] As a key component for storing, filtering and cooling the working oil of the steering system, the steering oil tank assembly must be connected to the atmosphere on the one hand to maintain the pressure balance in the system, and on the other hand, it must have excellent oil spill prevention and oil leakage functions , to prevent oil leakage. At present, oil leakage and oil leakage are common in steering oil tanks; for double-row light truck models, the cab cannot be turned over, and most of the current double-row models fix the oil tank under the maintenance port of the cab, which is not conducive to vacuum filling in the production line. Or it is arranged on the chassis of the whole vehicle, but it is not convenient for after-sales liquid level observation and oil replacement, and there is the problem of inc...
