As a Vacuum Brake Booster System Factory, let's talk about the types of new energy electric vehicle brake booster pumps.
1. Camshaft driven
Many of the accessories around the engine are controlled in the vacuum environment created by the engine running, limited by structure and type (diesel engine and gasoline direct injection engine), and some engines cannot provide a vacuum environment for the surrounding accessories. Therefore, adjustments have been made to the way the vacuum source is supplied, and it is a good idea to install a separate vacuum pump. Such a vacuum pump relies on a camshaft to drive the inner rotor of the pump, and the blade coaxially connected with the rotor rotates in an eccentric position. During the eccentric rotation, the volume above the blade is continuously squeezed and released, and the vacuum is created. surroundings.
2. Engine driven
The most common way to obtain a vacuum is to use the operating characteristics of the engine itself to connect the intake manifold to the vacuum booster through a line to introduce the vacuum generated by the engine during operation into the Brake Booster Vacuum Pump. This way of assisting has a subtle effect on the operating conditions of the engine.
3. Electric vacuum pump driven
Manufacturers are gradually working in the field of hybrid vehicles and pure electric vehicles. I wonder if you have thought about the "vacuum" problem. When the vehicle is driven by a motor, the original method of obtaining vacuum will not work, but the traditional structure is adopted. The dynamic system still needs to use more power than the driver's legs to push the master cylinder more effectively, and the electric booster pump is the best choice.
