Double-cylinder integrated crankshaft box structure of automobile air compressor

Abstract

The invention relates to a double-cylinder integrated crankshaft box structure of an automobile air compressor, and aims to solve the technical problem that the stability and the structural reliability are to be further improved during working of the existing same type of automobile air compressor. The double-cylinder integrated crankshaft box structure is characterized in that a cylinder body comprises two cylinders; the two cylinders are integrated with a crankshaft box body; an oil sealing opening is formed in the bottom of the crankshaft box body; and reinforcing ribs are arranged at the outer diameters of the two cylinders. The double-cylinder integrated crankshaft box structure of the automobile air compressor is relatively simple and relatively easy to manufacture and machine; the whole air compressor is relatively high in air tightness; the complexity of assembling and the precision problem are eliminated; meanwhile, the strength and the rigidity of a crankshaft box are improved, and the cold and hot deformation of the crankshaft box is reduced, so that the performance and the reliability of the air compressor are improved; and the double-cylinder integrated crankshaft box structure is suitable for being used by a new generation of automobile air compressors or being used as a structural improvement of the same type of products.

Description

technical field [0001] The invention relates to an automobile air compressor, which is a double-cylinder integral crankcase structure of the automobile air compressor. Background technique [0002] Automobile air compressors are mainly used for automobile braking, door and window opening and closing, tire inflation, etc. The cylinder part and the crankcase part of the existing automobile air compressor are independent of each other, that is, when installing, first install the crankshaft in the crankcase, then connect the connecting rod to the crankshaft, and finally connect the cylinder to the crankcase in a sealed manner. The above is The connection mode between cylinder and crankcase in ordinary automobile air compressor. The above-mentioned structure and connection method have the following disadvantages: 1. A certain assembly accuracy is required when the crankcase is connected to the cylinder, but in actual assembly, due to external factors or human factors, the assemb...
