Embodiment Construction

[0007] Such as figure 1 As shown, the present invention consists of a hydraulic oil tank 1, a pressure indicating gauge 4, an accumulator 7, an accumulator ball valve 8, a combined hydraulic valve 9, a hydraulic motor 10, a fuel tank return pipe 11, a fuel tank outlet pipe 13, and a fuel tank outlet pipe ball valve 12. It is characterized in that it also includes: exhaust valve 2, safety valve 3, pressure limiting check valve 5, and air storage tank 6. 3 communicates with the air chamber 15 on the upper part of the fuel tank, one end of the pressure limiting check valve 5 communicates with the air chamber 15 on the upper part of the fuel tank, and the other end of the pressure limiting check valve 5 communicates with the other end of the air storage tank 6. The pressure limit of the pressure limiting check valve 5 can be changed by adjusting the spring pressure in the check valve, and the pressure limit range is 0.5-2.0MPa. The safety pressure of safety valve 5 can be chan...

Abstract

The invention relates to a hydraulic oil tank for an air power starting system (hydraulic hybrid power system). The hydraulic oil tank is arranged on a hydraulic hybrid power vehicle or an air power energy-saving vehicle, and compressed air is pumped into the hydraulic oil tank through an air tank. Therefore, certain minimum pressure is kept in an air chamber above the hydraulic oil level in the hydraulic oil tank, and oil supply backpressure of a hydraulic pump under the energy storage working condition is formed; oil supply smoothness of the hydraulic oil tank is guaranteed, hydraulic noise in the work process is reduced, and energy storage efficiency is improved. The hydraulic oil tank is composed of a hydraulic oil tank body, a pressure indicator, an energy accumulator, an energy accumulator ball valve, a combined type hydraulic valve, a hydraulic motor / pump, an oil tank oil return pipe, an oil tank oil outlet pipe and an oil tank oil outlet pipe ball valve, and is characterized by further comprising an exhaust valve, a safety valve, a pressure limiting check valve and the air tank. The hydraulic oil tank belongs to automobile parts.

Description

technical field [0001] The invention relates to a hydraulic oil tank for an aerodynamic starting system (hydraulic hybrid system), which is installed on a hydraulic hybrid vehicle or an aerodynamic energy-saving vehicle, and is filled with compressed air into the hydraulic oil tank through an air storage tank, so that The air chamber above the hydraulic oil level maintains a certain minimum pressure, which forms the oil supply back pressure of the hydraulic pump during the energy storage condition, ensures smooth oil supply to the hydraulic oil tank, reduces hydraulic noise during work, and improves energy storage efficiency. It belongs to the category of auto parts. Background technique [0002] Patent application number 200610023489.X provides a bladder-type oil tank. The advantage of this oil tank is that the liquid is isolated from the air. The disadvantage is that it is difficult to realize the oil supply back pressure of the hydraulic pump under the energy storage cond...
