Embodiment Construction

[0055] exist Figure 1 to Figure 3 In , an example of a disc brake according to the invention can be seen. In this example, the brakes are fully electromechanically actuated, with an electromechanical actuator actuated by an electric motor providing braking during driving (service brake) and during parking (parking brake). Alternatively, disc brakes will be seen comprising hydraulic actuators.

[0056] In the following description, the same, similar or similar elements and components will be denoted by the same reference numerals.

[0057] The axial direction is parallel to the axis of the brake disc, while the transverse direction is perpendicular to the axis of the brake disc.

[0058] The upstream-downstream direction is considered to be the direction of axial movement of the piston during the braking phase.

[0059] The disc brake 10 comprises a caliper 12 having a rear housing 14 in which a brake piston 16 is mounted axially slidable along an axis X. The disc brake als...

Abstract

Disc brake comprising a yoke (15), at least one first brake pad (P1) mounted so as to slide within the yoke (15), the first brake pad (P1) comprising a pad support and a friction material, a caliper comprising at least one piston mounted so as to slide within the caliper in such a way as to move the first brake pad (P1) in relation to the yoke (15), at least one actuator configured to move the piston axially, and a separator device (34) inserted between the piston and the first brake pad (P1) forming an equaliser so as to distribute the thrust force exerted by the piston onto at least two zones of the first brake pad (P1), at least partially distinct from the projection of the piston onto the first brake pad (P1).

Description

technical field [0001] The invention relates to the field of disc brakes, in particular at least partially electrically actuated disc brakes. Background technique [0002] An example of a disc brake comprises a carrier for attachment to a stub axle of a motor vehicle, a caliper floatingly mounted relative to the carrier, two stoppers for contact with a brake disc rotatably attached to a wheel. moving film. Calipers include pistons that are movable by pressurized fluid to press a brake pad against a face of a brake disc. By reaction, the caliper slides and presses the other brake pad against the other face of the brake disc. [0003] When the pressure is released, the piston moves back and allows the brake pad it is in contact with to move away from the disc and braking force is removed. Another brake pad is also moved away from the other face of the brake disc. [0004] In the automotive industry, the function of the parking brake is to stop the vehicle at a standstill a...
