1. A brake caliper for a disc brake comprising:
a caliper body configured to straddle a brake disc to apply a braking action on a vehicle;
said brake disc defining an axial direction (A-A) directed either along or parallel to a rotation axis (X-X) of said brake disc; a radial direction (R-R) orthogonal to said axial direction (A-A) and a circumferential direction (C-C) orthogonal to said axial (A-A) and radial (R-R) directions, and a tangential direction (T-T) locally orthogonal to said axial direction (A-A) and said radial direction (R-R) and tangent to said circumferential direction (C-C);
said caliper body comprising at least one thrust device housing which accommodates a thrust device configured to apply a bias on at least one brake pad to abut said at least one brake pad against braking surfaces of said brake disc;
wherein:
said thrust device is operatively connected to a translating screw nut; said translating screw nut is operatively connected to a worm; said worm is operatively connected to a gearbox;
said worm is rotatably supported by a screw thrust bearing configured to support in rotatable manner said worm and to apply for said worm an axial reaction, that is a direct reaction prevalently along said axial direction (A-A);
at least one part of said gearbox placed near and operatively connected to said worm is rotatably supported by a gearbox thrust bearing configured to support in rotatable manner said at least one part of said gearbox and apply for said at least one part of said gearbox a radial reaction, that is a direct reaction prevalently along said radial direction (R-R); and wherein
said screw thrust bearing and said gearbox thrust bearing are a same thrust bearing,
wherein said thrust bearing comprises at least one radially inner slewing ring;
said gearbox comprises an epicyclic gear; wherein
said epicyclic gear comprises a fixed gear or an internally toothed body which cooperates with at least one planet gear, and wherein said at least one planet gear is rotatably supported about at least one planet gear pin;
wherein
said at least one planet gear pin is operatively connected to said at least one radially inner slewing ring; wherein
said at least one radially inner slewing ring comprises at least one pin housing and said at least one pin housing receives said at least one planet gear pin;
said at least one radially inner slewing ring is connected to said worm; and wherein
said worm comprises a screw shank;
said at least one radially inner slewing ring is connected to said screw shank to transmit action of said gearbox to said worm by said at least one radially inner slewing ring; or wherein
said worm comprises a screw shank; said at least one radially inner slewing ring is keyed to said screw shank to transmit action of said gearbox to said worm by said at least one radially inner slewing ring.
