How the braking process works

principles of service
During normal driving in braking, the steering wheel (i.e. the wheel) in the brake rotates with the axle under the brake pedal, and at the same time the torque is sent to the rotor through the dog shift unit, so that it rotates with it. and drive hub. The remaining parts, such as shell; air chamber film; disk for thermal insulation; internal friction block; outside friction block; elastic brake assembly; elastic regulator; During the brake, the air pressure pump enters the air chamber, so that the reaction film in the air chamber increases and pushes the internal assembly of the counter against the rotor, creating torque that delays the rotor delay. Under the influence of friction torque, the dog shift unit grips the rotor. When the speed is adjusted, a special curved inclined slot structure drives the rotor to move directly to the outer friction block assembly in the rotating head and roller on the drive hub until it meets the outer friction block, so that the inner and outer brakes squeeze the rotor simultaneously, resulting in Haldex slack adjuster significant friction . This friction torque is evenly divided between the inner and outer 5 friction blocks with 360 ° annular division, which enables greater friction over the parotor, thus affecting braking friction. Stable and functional.

2. Elastic brake assembly and air chamber film assembly in slack adjusting brake; the elastic brake assembly and the slack adjustment form the mutual solution brake charge and friction gap repair system. The main function of the elastic brake assembly is to start and stop the braking 2.1. During brake, the thermal insulation disc presses the friction block assembly under the action of increasing the air chamber film and drives the transmission axis of the slack adjuster to move in a rotor direction. The special gear gear between the teeth of the helical stand, or the inner slack adjustable clutch closed under the action of axial force, this special double gear shifts the axial movement to rotate, and the gear meshes and rotates with it. the upper gear of the sliding assembly of the slippery slope, and the distance between the pre-set friction block and the rotor is adjusted seamlessly by adjusting the sliding slider of the sliding slider, so that the brake obtains the appropriate degree of friction. 2.2. When parking When the wind stops, the air pressure in the repiston assembly decreases. Under the force of the exploding force of the disc spring in the assembly of the elastic brake, 10 ejection rods protrude out of the elastic brake which is placed over the hot disc discs to move toward the rotor. When the thermal insulation disc moves, the axial displacement of the driver shaft of the slack adjuster is provided, so that the slack adjustment can simply adjust the gap between the friction block and the rotor as described in section 2.1. At the same time, the ejector rod also passes through the heat exchanger disc. In addition, if the suction pressure drops to a certain value during driving, the upper rod in the elastic brake assembly pushes the friction through the upper thermal insulation disc under the action of the disc spring. The block does braking. When the air pressure is not enough, it looks like insurance to replace the brakes.

3. Wear the signal When the friction block in the brake is applied, the gear ring of the slide assembly and heat shield is attached to the steering wheel shaft of the wear signal which drives the driver's lift on the wear signal, and pull the piston cover of the wear signal to control. Depending on the step mark on the display screen, you can easily see the wear status of the friction block without brakes, it is easy to adjust and replace the friction block assembly.

3. When rapid release of the brake valve, the maximum suction pressure pushes the diaphragm into the valve for immediate release to close the air channel, so that it is not released. At this point, too much air enters the air chamber to perform braking. When the air flow stops or the air chamber air exceeds. .
