China wholesale heavy truck brake pad OEM high Quality WVA29171

A device that can provide a braking system for a vehicle, a pair of brake pads, which are set to face each other on the caliper body and are respectively set on both sides of the wheel disc; The first worm shaft component is connected to the motor component; The first worm gear component engages with the first worm shaft component and rotates with the rotation of the first worm shaft component; The second worm shaft component is connected to the first worm gear component and rotates together with the first worm gear component, and the second worm gear component is engaged with the second worm shaft component and includes multiple second teeth; And a linear motion conversion unit, which is connected to the second worm gear component and converts the rotational motion of the second worm gear component into linear motion. According to the vehicle braking device, the stiffness of the worm gear and worm gear shaft can be increased because the worm gear can withstand heavy loads, which basically prevents damage to the worm shaft.
