As we all know, the brake adjusting arm has a great impact on the vehicle driving safety, so the function of the automatic adjusting arm must also be vigilant. With the deepening of development, the development situation of automatic adjusting arm has been adjusted gradually. There are two kinds of adjustment arms, one is manual adjustment arm, the other is automatic adjustment arm, and their functions are more different. Obviously, the following describes the differences between automatic adjustment arm and manual adjustment arm.
Difference between automatic adjusting arm and manual adjusting arm
1. The guarantee of constant clearance is different
The use of the automatic adjusting arm ensures that the vehicle maintains a constant braking clearance after driving for a period of time, which ensures a continuous braking effect of the clearance, regardless of the degree of wear. The installation of automatic adjusting arm is less difficult than that of manual adjusting arm, which is also the advantage.
2. Shorten braking reaction time
The automatic adjusting arm can also realize this function by reducing the consumption of compressed air to shorten the braking reaction time, which is of great significance to ensure the safety function of the vehicle. In order to ensure the safety of vehicle driving and maintain the relative stability of pedal travel and the working balance between brakes, it is necessary to adjust the brake clearance (the adjustment described here refers to the adjustment during use). The adjustment is divided into manual and automatic adjustment.
3. Different brake Equalization Effects
Especially when the number of axles is increasing, the automatic adjusting arm can play a more prominent braking balance effect. At the beginning of braking, the brake adjusting arm will the clearance angle of camshaft and the clearance angle, and accurately record the wear. At this time, the cam angle stroke is in the clearance area, which is characterized by little change in braking torque. As the brake continues, the cam angle stroke enters the elastic deformation zone, and the braking torque rises sharply until the vehicle stops. The automatic adjusting arm releases the pedal, the brake returns, the brake torque decreases, and the cam angle stroke returns to the gap area.
To sum up, it can be seen that there are significant differences between the automatic adjusting arm and the manual adjusting arm. In contrast, the automatic adjusting arm has guaranteed after-sales service, and its application advantages are more obvious. Among them, the guarantee of constant clearance is higher, the braking reaction time is shortened, and the braking equalization effect is good. The automatic adjusting arm is based on the excess clearance recorded during braking, and the internal adjusting mechanism drives the camshaft to a certain angle through the worm gear to complete the adjustment.
