A multi-disc brake is provided. The brake can include a radial wear pin cartridge for wear indication. The brake can include an integrated water jacket for cooling.

A braking band extends between an inner diameter and an outer diameter. The braking band has two plates having inner surfaces delimiting a gap, outer surfaces having opposite flat circumferential portions and a plate body having an extension in axial direction. The plates are joined by connecting elements. At least one plate has at least one projection projecting into the gap without reaching the opposite plate, forming a localized narrowing of the gap and a thickening of the plate body, creating a localized increase of the thickness of plate. The projection extends from a first connecting element to an adjacent connecting element, connecting them, and along the circumferential direction, connecting at least two adjacent connecting elements. A group of projections extends circumferentially along a discontinuous annular path, avoiding a uniform distribution in circumferential direction.

A brake device, configured to be installed directly on a driving axle or through a hub, wherein said device includes a first brake disc joined to the axle sharing rotary motion, a first container disc and a second container disc configured to be moved in the axial direction of said axle. The container discs are positioned on each side of the brake disc, such that both are configured to be moved in the axial direction towards the linings of the first brake disc and to exert a pushing pressure thereon, producing the braking of the brake disc and, therefore, of the driving axle whereon it is assembled. Furthermore, the container discs comprise an inner circuit configured to accommodate the passage of a coolant configured to cool them.

A radiating spacer includes a plate body having a backing plate facing side and a caliper facing side, with the backing plate facing side having a plurality of cooling grooves and the caliper facing side having a planar caliper piston contact area. The cooling grooves extend partially into the plate body to provide additional cooling of the brake pad and braking assembly. The planar caliper piston contact area is configured to provide a flat surface for contact with a caliper piston. In some embodiments, the radiating spacer and the backing plate are made from different metal materials having certain thermal conductivity coefficients to help promote advantageous heat distribution.

The first set of mounting flanges may extend from the first panel and may be spaced apart from the second panel. The second set of mounting flanges may extend from the second panel and may be spaced apart from the first set of mounting flanges.

An aircraft braked wheel comprising a rim integral with a hub for rotationally mounting thereof on an axle of the aircraft along an axis of rotation, the wheel being equipped with a heat shield (11) extending opposite an inner face of the rim to protect the rim from the thermal radiation generated by a stack of discs extending inside the rim, characterized in that the heat shield has a face facing the discs (15) which has longitudinal ribs (16) extending in operation parallel to the axis of rotation of the wheel.

The invention discloses a friction simulating device, comprising: a first driving shaft, a first driving gear, a second driving gear, a second driving shaft, a plurality of friction plates and a driving mechanism. The first driving gear is coaxially fixedly connected to the first driving shaft. The second driving gear is located on a radial outer side of the first driving gear and is provided coaxially with the first driving gear. The second driving shaft is coaxially fixedly connected to the second driving gear. The plurality of friction plates being provided subsequently between the first driving gear and the second driving gear in a direction of an axis of the first driving gear, wherein some of the friction plates are axially movably connected to the first driving gear in a circumferential direction, and the other friction plates are axially movably connected to the second driving gear in the circumferential direction. The friction simulating device is able to simulate the friction applied to the wheels of the vehicle by the ground.

An internally ventilated brake disc with a disc coning reducing arrangement is provided in which temperature differences between inboard and outboard sides of the brake disc are minimized in order to reduce coning-causing differential thermal expansion. Between a radially inner region of a brake disc that includes brake disc-to-axle hub mounting features and a radially outer region the mass of the inboard side of the brake disc is distributed in a manner that reduces the amount of differential thermal expansion occurring during brake application between the inboard and outboard sides of the brake disc, thereby minimizing thermally-induced coning effects. The inboard side disc plate portion may having an increasing axial thickness in the direction from the radially outer region to the radially inner region, providing additional material mass to receive and dissipate heat energy received during a braking event.

A motor assembly having a brake device and a downsized cooling system is provided. The motor assembly comprises a drive motor, a brake device that stops rotation of a motor shaft, and a casing that holds the drive motor and the brake device. The motor assembly further comprises a hollow passage formed in the motor shaft to allow cooling medium to flow therethrough, a centrifugal passage formed in the brake rotor from the hollow passage to an opening of the brake rotor, and a return passage that returns the cooling medium discharged from the opening to the hollow passage.

The invention relates to an autonomous retarder system for a vehicle including a retarder (10) having a central rotor (11) and two stators (12), one on each side of the rotor (11). The rotor (11) is rigidly coupled to an axle (1). A generator (20, 30, 50) is also included, coupled to the retarder (10), for supplying same with electrical energy.
