Abstract
A method for manufacturing a disc brake, the disc brake having a brake caliper and a brake actuation mechanism being supported in it, in which the brake actuation mechanism includes an amplification mechanism for introducing a clamping force, an adjustment device for compensation of lining wear with a torque clutch, a thrust element for transmitting the clamping force onto a brake disc and a reset device, which components are arranged around a rod, in which the torque clutch is formed as a roller-ramp-mechanism. A spring force can act onto the torque clutch by means of the reset device thereby forming a torque limit.
Claims45
A method for manufacturing a disc brake, the disc brake including a brake caliper, which overlaps at least one brake disc, and a brake actuation mechanism, which has:
- an amplification mechanism for introducing a clamping force,
- an adjustment device for compensation of lining wear, the adjustment device comprising a torque clutch,
- a thrust element for transmitting the clamping force onto the brake disc, and
- a reset device, in which the amplification mechanism, the adjustment device, the thrust element and the reset device are mounted in functional cooperation in the brake caliper by means of a rod, which is non-moveably supported in axial direction in the housing of the brake caliper, characterized in that the torque clutch is formed as a roller-ramp-mechanism which acts between the amplification mechanism and the thrust element, in which the rollers of the roller-ramp-mechanism are moveably arranged co-axially with respect to the rod;
- the method comprising the steps of:
- inserting of an adjustment pinion into the housing of the brake caliper and fixing on a shaft in the housing,
- inserting of a first unit comprising the amplification mechanism, the adjustment device having a gear wheel and the reset device and the rod keeping these elements together into the housing of the brake caliper, in which the rod will be inserted through a rear opening of the housing of the brake caliper so that the gear wheel comes into threaded engagement with the adjustment pinion,
- attaching of a support tool with an adjustment tool, in which the adjustment tool is rotatably guided in the support tool, at the brake caliper such that the adjustment tool attaches at the end of the rod facing the brake disc,
- rotating of the adjustment tool so that an opposite free end of the rod will be displaced through the rear opening in the housing of the brake caliper to the outside,
- attaching of at least one support and fixation means at the free end of the rod,
- rotating of the adjustment tool in reverse direction so that the rod is displaced in opposite direction and interlocks the at least one support and fixation means in the rear opening in the housing of the brake caliper and thereby the rod will be non-rotatably fixed in the housing in axial direction, and
- removing of the support tool with the adjustment tool, in which after fixation of the rod the reset device is biased by a defined pretension.
