Do You Know, The Electric Brakes Are Key Parts In Audi Q3 S Line For Sale
The electric parking brake is increasingly common in new vehicles. In addition to protecting the vehicle from unintentional start-up, it allows you to put other practical functions into practice. So, for a used buyer of Audi q3 s line for sale, it is necessary to know that how two system variants work; as well as to follow the procedures in the event of a fault and the points to be observed by the experts in the event of repairs to the wheel brake.
The Electric Brakes
The electromechanical parking brake has the task of preventing the vehicle from moving when stationary. It also complies with legal regulations that provide for a second independent braking system and additional safety and comfort functions. in the case of the Audi, the parking brake mechanism consists of a DC motor, an oscillating gear reducer and a threaded shaft. The components are mounted directly on the rear brake calipers and allow the rotation of the motor to be transformed into small vertical movements of the brake piston. Therefore the DC motor, through a belt-drive, starts the oscillating gear reducer. In this circumstance, the speed of the drive motor is also reduced for the first time. Through the ratio of the belt drive, the number of revolutions is reduced to 1: 3. The speed is reduced by the oscillating gear reducer again. The speed of the gearbox is reduced by a factor of 147 compared to the number of revolutions of the DC motor.
The Conversion
The conversion of the rotational movement into the lifting movement takes place via a spindle, which is driven directly by the swashplate mechanism. In the brake piston, there is a cylinder that moves back and forth in the piston. To prevent the cylinder from rotating, it is ground in two places. A nut is placed on the front end of the cylinder and moves along the threaded pin when the threaded shaft turns. The number of revolutions of the DC motor is measured by means of a Hall sensor and transmitted to the control unit which in this way can calculate the lifting stroke. When the parking brake is operated, the nut is moved forward through the rotation of the threaded shaft. To be precise, it is fact that the condition and function of Brakes can set or reset the used Audi q3 s line price; so, it becomes necessary for a buyer to be careful about that.
The Relative Switch
The cylinder presses the pads onto the brake disc using the piston. If the parking brake is released, the nut is pulled back by rotating the threaded shaft backward and the brake piston is loosened. As in a normal braking procedure, restoring the shape of the piston seal ring causes the latter to be returned to its original position. The entire system also includes a control unit with an integrated tilt sensor, control lights and the actuation switch in the center console. To activate the parking brake, pull the relative switch, to release the brake press the switch. The activation of the parking brake is indicated by the control lamp in the dashboard and the operating switch. A special feature of the parking brake is that it can be activated even when the ignition is off. But it can only be released with the ignition on.
