Automobile high-pressure oil pump with flow dividing and energy saving effects

Abstract

The invention discloses an automobile high-pressure oil pump with flow dividing and energy saving effects. The automobile high-pressure oil pump comprises a high-pressure oil pump body, a control mechanism is arranged at the front end of the high-pressure oil pump body and comprises a control box fixedly arranged at the front end of the high-pressure oil pump body, and a control groove is formed in the inner wall of the control box; a moving groove is formed in the side, close to the control groove, of the inner wall of the control box, a gear shaft is movably arranged on the inner side of the control box through a rotating shaft, and a clamping block is slidably arranged on the inner side of the control groove. According to the automobile high-pressure oil pump with the flow dividing and energy saving effects, a motor is started to enable a connecting frame to drive a first gear plate to move, so that a gear shaft drives a second gear plate to move, a control rod drives a moving plate to move, the flow dividing purpose can be achieved, and therefore the flow dividing and energy saving effects are achieved.

Description

technical field [0001] The invention relates to the technical field of high-pressure oil pumps, in particular to an automobile high-pressure oil pump with split flow and energy-saving effects. Background technique [0002] The oil pump is a light and compact pump, which can be divided into three categories: inline type, distribution type and single type. The oil pump needs a power source to operate, and its lower camshaft is driven by the engine crankshaft gear. The oil pump proposes an oil pump with a housing made of aluminum-containing material and a movable molded part set in the housing. parts, wherein the movable molded part is at least partially made of a sinterable iron-based alloy material containing at least one austenite, and wherein the mold made of a sinterable material The workpiece has a thermal expansion coefficient that is at least 60% of the thermal expansion coefficient of the shell; the traditional high-pressure oil pump for automobiles has some disadvant...

Problems solved by technology

The oil pump needs a power source to operate, and its lower camshaft is driven by the crankshaft gear of the engine. The oil pump proposes an oil pump with a housing made of aluminum-containing material and a movable molding set in the housing. parts, wherein the movable molded part is at least partially made of a sinterable iron-based alloy material containing at least one austenite, and wherein the mold made of a sinterable material The workpiece has a thermal expansion coefficient that is at least 60% of the thermal expansion coefficient of the shell; the traditional high-pressure oil pump for automobiles has some disadvantages. The oil pump can't be split to save energy, which leads to waste of resources, unsatisfactory energy-saving effect, and inconvenient use
