A brake system includes a brake disc, rotary movable around a disc axis, and a brake mechanism. The brake mechanism includes a brake pad, movable in a first direction, a cylinder having a piston movable in a second direction, a lever rotary movable around a lever axis, the lever being connected to the piston, a cam element, arranged to convert a rotary motion of the lever around the lever axis, into a translation motion in the first direction, and a rod, expanding between the brake pad and the cam element. The lever, the cam element and the rod are housed in a housing. Considering a plane including the disc axis and the first direction, the lever axis is inclined relative to the plane, at an angle different from 90°.

A disc brake for a commercial vehicle has a brake caliper spanning a brake disc on the vehicle side, in which brake caliper a clamping device is arranged which has a pivotable brake lever engaging in at least one bridge carrying a brake plunger, which at the same time is directly or indirectly supported at the inner side of a wall of the brake caliper. The contact area of the bridge at the brake lever or of the brake lever at the brake caliper is configured as a pivot bearing having a bearing shell cross-sectionally configured as an arc forming a part of the pivot bearing. The bearing shell is placed in a seating. The disc brake is configured such that the bearing shell is located in the pivoting direction of the brake lever with its opposite longitudinal borders at stop edges, which longitudinally limit the trough-shaped seating.

To produce a combined service brake cylinder and spring-loaded brake cylinder for a vehicle brake system, force-actuation path characteristic curves of the brake system with the elements that can be actuated by a storage spring of the spring-loaded cylinder are measured/recorded under different operational conditions. Force-actuation characteristic curves of different storage springs for use in the spring-loaded cylinder are also measured/recorded. The minimum necessary actuation stroke of the piston of the spring-loaded cylinder and the minimum necessary spring force for a storage spring to effect a parking brake function are determined by the intersection of the force-actuation curves of the brake system with those of the storage springs. The storage spring that generates a sufficient actuation force under certain operating conditions and the dimensions resulting from the smallest possible piston actuation stroke are selected for producing the combined service brake cylinder and spring-loaded cylinder.

Various systems and methods for braking a vehicle are provided. In one embodiment, a brake assembly is provided that includes a lever attachment interface pivotally coupled with two degrees of freedom to a joint between a first lever and a second lever and a brake cylinder coupled to the first lever and designed to engage and disengage a brake lining in a brake component. The brake cylinder includes a slack adjuster configured to adjust a throw of the second lever.

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.

A knuckle for a heavy-duty vehicle self-steering axle/suspension system that includes integrally formed structure for mounting components of a drum brake system. The knuckle includes a spindle that is welded directly to the knuckle and a discrete tie rod arm bolted to the knuckle.

A braking system for a vehicle includes an indicator device provided to reliably indicate a state of a parking brake of the system, while being simple, convenient, and economical. The system includes a body that delimits a service brake pressure chamber and/or a parking brake pressure chamber, a parking brake movable relative to the body, an unlocking part for unlocking the parking brake connected to the parking brake pressure chamber and accessible from outside the body, and a parking brake indicator device. The indicator device is configured to receive a position of the unlocking part via a state pipe and an indicator of supply and/or the venting of the service brake pressure chamber and/or of the parking brake pressure chamber. This information is processed in to detect and indicate an engaged state or a disengaged state of the parking brake.

A heavy vehicle drum brake shoe guide and an assembly comprising the brake shoe guide are described. In one aspect, there is provided a brake shoe guide for attachment to a drum brake shoe by a pin fastener, to prevent brake shoe misalignment. There is also provided a brake shoe guide assembly including at least a brake shoe guide and a pin fastener for securing the brake shoe guide to a drum brake shoe. The brake shoe guide described herein is simple to fit to a standard, off the shelf brake shoe, and can be retrofitable to a brake shoe and/or brake assembly. Moreover, the brake shoe guide assembly described herein can retain the cam follower roller to the brake shoe, and act as an axle for the cam follower roller, eliminating the need for a separate retainer clip. Further still, the guide and the assembly of which it forms a part can be used with drums of various sizes.

A spring brake actuator for applying a brake of a vehicle includes a housing containing a diaphragm that separates the housing into first and second chambers. A clutch actuator device is for selectively compressing a compression spring such that the spring brake actuator is operable in a plurality of states including a parking state, driving state, and a braking state.

An omni-wheel may include a shaft, a plurality of rollers, and a braking device. The plurality of rollers may be circumferentially arranged about the shaft and arranged radially outward from the shaft. The braking device may include an at least one flexible clutch member, an at least one brake pad, and an actuator. The at least one flexible clutch member may have an outer diameter arranged about the shaft. The at least one brake pad may be arranged on the outer diameter of the at least one flexible clutch member. The actuator may be arranged to axially displace the at least one flexible clutch member. The at least one flexible clutch member may expand radially outward when axially displaced by the actuator, which may displace the at least one brake pad arranged on the outer diameter of the at least one flexible clutch member radially outward to contact at least one of the plurality of rollers, preventing rotation of the roller.
