Do you know about the new energy electric vehicle Brake Booster Vacuum Pump?

Pulished on Dec. 27, 2019

Each component in the new energy vehicle is close and complementary relationship and no one can do it. 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. Let's watch the introduction of new energy electric vehicle brake booster pump with EV Brake Booster Vacuum Pump Supplier.

Camshaft drove:

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.

Engine-driven:

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.

Brake Booster Vacuum Pump:

Everyone started to make efforts in the field of hybrid vehicles 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 vacuum is not feasible, but the traditional structure of the system 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.

Introduction of new energy electric vehicle brake booster pump——structure

The brake booster pump is a large-diameter vacuum chamber. Inside it is a diaphragm (or piston) with a push rod in the middle, which divides the chamber into two parts, one part communicates with the atmosphere, and the other part passes The pipe is connected to the engine intake pipe. It is based on the principle of sucking air when the engine is working, causing a vacuum on one side of the booster pump and a pressure difference with respect to the normal air pressure on the other side, and using this pressure difference to strengthen the braking thrust. If there is even a small pressure difference between the two sides of the diaphragm, due to the large area of the diaphragm, a large thrust can still be generated to push the diaphragm to the side with the lower pressure. The vacuum booster system is also used to control the vacuum entering the booster pump to move the diaphragm when braking, and through the intermodal device, the pusher on the diaphragm is used to assist manpower to step and push the brake pedal. Therefore: When the engine is off, there will be no assistance due to the absence of an intake vacuum, and the manual force required for braking will be great. It should be noted here that many novices believe that the engine is not braked when the engine is off, which is wrong. The correct thing is that the engine is off, and the manual pedaling force required for braking will become very large because it is not assisted.
