Brake caliper and spring unit for a brake caliper

A brake caliper (10) for a vehicle disc brake, in particular an air disc brake of a commercial vehicle, the disc brake having a pair of brake pads (20a, b), and a brake disc (30) positioned in between the brake pads (20a, b), the brake caliper (10) comprising:

• a thrust piece (110) movably mounted in an axial direction (A) in the brake caliper (10), wherein the thrust piece (110) moves at least one of the brake pads (20a, b) relative to the brake disc (30),
• an adjuster unit (200) in threaded engagement with the thrust piece (110), and
• a spring unit (300) operatively coupled to the adjuster unit (200) and the thrust piece (110), wherein the spring unit applies a spring force in the axial direction (A) between the thrust piece (110) and the adjuster unit (200),
• wherein the spring unit is disposed axially between the thrust piece (110) and the adjuster unit (200);
• wherein the spring unit (300) has a latching element (310, 320, 330) and the adjuster unit (200) includes a corresponding latching interface (220), wherein the latching element (310, 320, 330) is arranged to engage the latching interface (220) when the adjuster unit (200) is in threaded engagement with the thrust piece (110), and
• wherein the spring unit (300) includes a radially extending mounting element (340) disposed in a positive connection with a recessed mounting interface (112) defined in the thrust piece (110);
• wherein the positive connection blocks rotation of the spring unit (300) relative to the thrust piece (110);
• wherein the spring unit is in the form of a closed loop ring that extends fully circumferentially around the adjuster unit (200).
