Working Principle Of Automobile Air Conditioning Damper Actuator

The application of automotive Air Actuator system is becoming more and more common, and it has become a key component of the comfort of passenger cars. It can adjust gas temperature, ambient humidity, cleanliness, exhaust volume and wind frequency to ensure that passengers are safe under various external climates and standards. In a live natural gas environment, as a key component of the air-conditioning double-action mechanism, the actuator is the tail of the air-conditioning electronic control command. The stepping motor is a very important structure. At present, the stepping motor of the air-conditioning damper actuator is divided into two parts, the upper casing and the lower casing. When the stepper motor is installed, a part of the upper and lower casings should be installed with coaxial output, but the axial force between the upper and lower casings during the entire installation process is not large, which endangers the use of the stepper motor.

The working principle of the air-conditioning wind Door Actuator mechanism of the car air conditioner 1 The working principle of the door actuator of the car air conditioner. The inlet and the opening or closing of the valve. The actuator is connected to the air conditioning wind direction selection knob of the vehicle cab.

The rotation of the motor is the short-circuit part of the actuator. According to the rotation of the motor, the lever is connected with the intake valve to open or close different intake valves. Currently, the technical linkage of the actuator is that the actuator lever immediately opens or closes the intake valve according to the support rod or the rope. If the connection is not smooth, it is easy to generate ground stress and torque, and it is easy to cause the rope to break or the support rod to break.

Generally, the throttle actuator is based on the micro-motor drive system to drive the freighter to decelerate, then drive the output transmission gear to rotate, and output a certain speed ratio and torque to drive the system arm. The rotating part operates according to a spring brush mounted on the output drive gear. The spring brush portion on the circuit board determines the angle of rotation. Typically there are three control loops. One is operated by the integrated chip of the transmission system. This motor is mainly used in the damper mode. The other is to use the feedback working voltage to clearly output the rotation position of the driving gear. The control panel feedbacks the operating angle according to the working voltage value of the spring brush. This type of motor is often used in mode or temperature dampers, and this type of motor is often used in new return dampers.
