A disc brake for a vehicle, having a first and a second brake lining (2a), and a brake disc (1) which is arranged between them, and a brake calliper which engages over the brake disc (1) with a brake calliper housing (6), in which a brake application device is arranged, wherein the brake application device comprises a pressure piece (3) which can be applied against the first brake lining (2a), wherein a boot (5) is provided for protecting the interior of the brake calliper housing against contaminants, wherein the boot (5) is fastened by way of a first end region (5a) to the brake calliper housing (6) and by way of a second end region (5b) to a sheet metal arrangement (7) consisting of a sheet metal plate (8) and a sheet metal ring (9) which is arranged coaxially with respect thereto and is connected in an integrally joined manner to said sheet metal plate (8), wherein the sheet metal plate (8) is arranged between an end side of the pressure piece (3) and the first brake lining (2a), wherein the sheet metal ring (9) is arranged between the boot (5) and the brake lining (2a) for protecting the boot (5) against heat radiation which is generated by way of braking operations on the brake linings (2a, 2b) and the brake disc (1), and wherein the sheet metal ring (9) has at least one cut-out (11) for reducing its flexural stiffness.

A gyratory crusher spider wall shield for releasable mounting to a radially inward facing face of a spider positioned on top of a shell of a gyratory crusher includes a primary protection wall positionable over the inward face of the spider and a rear wall attachable to an outer annular fixating ring positionable axially intermediate a material input hopper and the spider.

A removable brake cover apparatus is disclosed including a sidewall presenting frontal and posterior surfaces and a circumferential wall extending transversely from the sidewall to define a brake rotor receiving cavity adjacent the posterior surface of the sidewall. A brake caliper pocket having a limited circumferential extent is disposed along the sidewall and the circumferential wall to define a brake caliper receiving cavity adjacent the brake rotor receiving cavity. Engagement fingers extend radially into the brake caliper receiving cavity to engage a brake caliper received therein with an audible and/or tactile indicator defining a fully installed position of the brake cover apparatus. Locking recesses extend radially into the brake rotor receiving cavity to engage a brake dust shield received therein. Multiple ones of the brake cover apparatus disclosed are nestable with one another in a stacked arrangement wherein the engagement fingers and locking recesses perform locating and anti-rotation functions.

A disc brake boot and a disc brake including the same are provided. The disc brake boot includes: a main body formed with a hollow that runs lengthwise through which a guide rod passes and is coupled; a first outer projection that is formed on an outer side of the main body in such a way as to protrude a set distance from one edge of the main body, along the perimeter of the main body; and a second outer projection that is formed on the outer side of the main body in such a way as to protrude a set distance along the perimeter of the main body, spaced apart from the first outer projection.

A brake dust cover is installed in a brake system including a rotor disposed on an inner diameter side of a rim of a wheel and a caliper interposing and holding the rotor with brake pads and includes a main body, an extension, and an opening. The main body is disposed adjacent to the rotor on an inside of the rotor in a vehicle width direction, that is disposed so as to overlap at least a part of the rotor when viewed from an axle direction, and that is disposed such that an outer circumferential edge portion thereof is separated from an inner circumferential surface of the rim. The extension extends from a part of the outer circumferential edge portion of the main body to an outer diameter side. The opening is formed in the main body, and air in a wheelhouse is introduced toward the rotor through the opening.

Disclosed herein a electromechanical brake includes a power converter including a nut provided in a cylinder portion of a caliper housing slidably coupled to a carrier and configured to rotate by receiving a driving force from an actuator, and a spindle connected to the nut and configured to move forward or backward by rotation of the nut in a first direction or a second direction; a pressing member coupled to a front side of the spindle and configured to press a pad plate; and a position adjuster screwed into the cylinder portion so that the power converter is mounted and configured to adjust a relative position of the caliper housing in response to an operation of the power converter.

An airbrake filter assembly for reducing dust produced by air brakes on a vehicle includes a sock that is comprised of a fluid permeable material for passing air therethrough. The sock is positionable on a pressure release tube of an air brake system on a vehicle to slow the velocity of air being expelled from the pressure release tube. A cup is positioned in the sock and the cup is comprised of an air impermeable material to inhibit air from passing therethrough. The cup is aligned with the flow of air outwardly through the pressure release tube such that the cup directs the flow of air laterally through the sock. In this way the cup inhibits the flow of air from producing dust that would result if the air is blown onto the ground.
