What are the types of new energy electric vehicles Brake Booster Vacuum Pump?

Pulished on Nov. 29, 2019

Each component in the new energy vehicle is a close and complementary relationship, and no one can do it. As an Electric Brake Booster Manufacturer, I have some information to share with you. The brake booster pump, commonly known as the brake booster pump, controls the vacuum entering the booster pump during the braking process to move the diaphragm, and through the intermodal device, the pusher on the diaphragm is used to assist manpower to step on and push the brake pedal. , Thereby amplifying the driver's pedaling force. Today I will tell you about the types of new energy electric vehicles Brake Booster Vacuum Pump.

Many accessories around the engine are controlled in the vacuum environment formed when the engine is running, which is limited by the structure and type (diesel engines and gasoline direct injection engines), and some engines cannot provide the vacuum environment to meet the work of the surrounding accessories. Therefore, adjustments have been made in the way the vacuum source is provided, and it is a good idea to install a separate vacuum pump. This type of vacuum pump relies on a camshaft to drive the internal rotor of the pump, and the blades coaxially connected to the rotor rotate at an eccentric position. During the eccentric rotation, the volume above the blade is continuously squeezed and released, and this process creates a vacuum. surroundings.


The most common way to obtain a vacuum is to use the operating characteristics of the engine to connect the intake manifold with a vacuum booster through a pipeline, so that the vacuum generated by the engine is introduced into the booster. This way of assisting will have a slight impact on the operating conditions of the engine.

Manufacturers are gradually making efforts in the field of hybrid and pure electric vehicles. I wonder if you have thought about the "vacuum" problem. When the vehicle relies on the motor, the original method of obtaining a vacuum will not work, but the traditional structure is adopted. The power system still needs to use the power of the driver's legs to push the brake master cylinder more effectively. The electric power pump has become the best choice.

Since it is a brake booster pump, it must be a component on the brake device, which plays a significant role in braking. For the question "why the car can't step on the brakes when the car is off," the corresponding answer is given: after the car is off, the brake booster does not work. For naturally aspirated engines, and assisted vacuum is formed by the throttle effect of the intake pipe throttle. For turbocharged engines, the vacuum comes from a vacuum pump. Therefore, the vacuum can only be generated when the engine is running. After the flameout, the vacuum source is no longer sustained, and there is no way to provide assistance. The above is all about the types of brake booster pumps for new energy electric vehicles. If necessary, please consult.
