Braking device

Braking device for a wheel of a vehicle comprising:

• a caliper with brake linings guided therein,
• at least one brake disk arranged between the brake linings which is axially displaceable in a non-rotatable manner with respect to the wheel, and
• a pneumatically operable adjusting device, which has an exclusively rotationally movable drive shaft as a mechanical transmission element, for generating a pressure of the brake linings on the brake disk,
• wherein the caliper is constructed as a fixed caliper and, when the adjusting device is operating, only one of the brake linings, arranged on opposite sides of the at least one brake disk, carries out an application movement,
• wherein the adjusting device comprises a ball screw with a ball screw spindle, which is caused to rotate by the drive shaft, and a corresponding yoke, the ball screw being constructed for generating an axially acting pressure of the brake linings onto the brake disk, and
• wherein the adjusting device comprises at least two pressure pistons, which are directly operatively connected with the ball screw spindle by way of the yoke, the ball screw spindle, on the one hand, being rotatably disposed in a first bearing of a housing and, on the other hand, by its facing-away free end, being rotatably disposed in another bearing of a bearing plate of the caliper.

• wherein the caliper is constructed as a fixed caliper and, on one end, is connected by a fastening element with an axle element and, on a bearing plate of the caliper, a housing is fastened for bearing a mechanical adjusting device comprising a ball screw with a drive shaft, and
• wherein, on the housing, as well as on the bearing plate, the adjusting device is supported so that, by a yoke, pressure pistons, which can be jointly acted upon by pressure, are guided in an axially adjustable manner with respect to the brake linings and the at least one brake disk.
