Abstract

The invention discloses a hydraulic two-way check valve for a steering system of a new-energy bus. The hydraulic two-way check valve comprises a three-way body (1) and two valve bodies (2) arranged at two inlets of the three-way body (1), wherein the two valve bodies (2) are arranged in parallel; an outlet of the three-way body (1) is an oil outlet (1-1); each valve body (2) comprises a valve cavity (2-1) and an oil inlet (2-2), one end of the valve cavity (2-1) is communicated with the corresponding oil inlet (2-2) while the other end of the valve cavity (2-1) is communicated with three-way body (1), and a valve element component for controlling connection or disconnection between the valve cavities (2-1) and the corresponding oil inlets (2-2) is arranged in the valve cavity (2-1) and comprises a valve element (3), a spring (4) and a retaining ring (5), which are sequentially arranged in the oil inlet direction; the retaining rings (5) are fixed on inner walls of the corresponding valve cavities (2-1); one end of each spring (4) is fixed to the corresponding valve element (3), and the other ends of the springs (4) are fixed to the corresponding retaining rings (5). The hydraulic two-way check valve, provided by the invention, for the steering system of the new-energy bus, has the advantages of compact structure, small assembly space and good safety.

Description

technical field [0001] The invention relates to the technical field of automobile steering systems, in particular to a hydraulic two-way check valve for a new energy passenger car steering system. Background technique [0002] At present, most of the steering pipelines connecting the mechanical steering pump and the electric steering pump in the hybrid structure on the market need to use two check valves, a three-way joint, three straight joints, a short steel pipe and a 90-degree elbow joint at the same time. There are eight parts in total. The assembly of this structure is more complicated, and the workshop production time is longer, which affects the production efficiency, and there are many connection joints, complicated pipelines, prone to falling off, oil leakage, and potential safety hazards. Contents of the invention [0003] The object of the present invention is to provide a hydraulic two-way check valve for the steering system of a new energy passenger car, whi...
