Abstract

The invention relates to an automobile electric vacuum pump, and belongs to the field of automobile brake. An air filter is mounted on an upper shell body. An impeller is mounted between the upper shell body and a lower shell body. Motors are mounted on the bottom of the lower shell and are connected with the impeller through a gear set. A protective cover is installed on the outer portion of the gear set. A machine body air outlet is placed between the upper shell body and the lower shell body, a vacuum generator is connected with the machine body air outlet, and the vacuum generator is provided with a vacuum connector. A silencer is connected with an outlet of the vacuum generator. The automobile electric vacuum pump has the advantages of being novel in structure, effectively overcoming the existing defects, better obtaining a rapid, efficient, stable and low-noise vacuum source, improving the safety, reliability and comfort of an automobile, and solving the problem of the vacuum source in an electric automobile braking system.

Description

technical field [0001] The invention belongs to the field of automobile braking, in particular to an electric vacuum pump for new energy automobiles. Background technique [0002] Automotive electric vacuum pump is a key component in the braking system of new energy vehicles. Its working principle is to use an independent motor or vehicle power source to drive the impeller fan, use the high-speed airflow generated by the fan to quickly flow through the vacuum generator, and form a jet of air at the nozzle inside the vacuum generator to generate airflow entrainment. , the air around the nozzle is sucked away, which can quickly generate a partial vacuum. Lead out the part where the vacuum is generated through the vacuum joint and connect it to the car vacuum booster. In the past, electric vacuum pumps for automobile braking systems used moving structures such as diaphragms, rotary vanes, and pistons to extract air from the cavity to generate negative pressure. These working...
