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.

A brake rotor assembly can include a structural part having a receiving surface and at least one friction surface parts having a contact surface. The friction surface part can be fixably attached to the receiving surface of the structural part such that the contact surface faces away from the receiving surface of the structural surface to form at least part of an annular braking surface arranged concentrically around an axis of rotation of the structural part.

A brake rotor having first and second panels and first and second sets of mounting flanges. The first set of mounting flanges may extend from the first panel and may be spaced apart from the second panel.

A ventilated brake disc includes first and second plates, and a plurality of connecting ribs and protruding ribs. The first and second plates are each shaped as a circular ring, and each have inner and outer surfaces. The inner surfaces of the first and second plates face each other. The first and second plates collectively form a central via and an outer periphery of the ventilated brake disc. Each connecting rib is integrally connected to the inner surfaces of the first and second plates, and elongated in shape, thereby defined with two opposite ends, which are oriented toward the central via and the outer periphery respectively. Each protruding rib protrudes integrally from the inner surface of the first or second plate, and is not connected to the other plate and located between two connecting ribs. The present invention simultaneously attains lightweight and great structural strength and heat dissipating effect.

The at least one bridge has at least one ventilation opening and at least one conveying channel fluidically connected to the outside of the caliper body through the at least one ventilation opening. The least one ventilation opening directly faces in an axial direction the inside of the caliper body with the outside of the caliper body to direct heat generated inside the caliper body in an outer axial direction towards the outside of the caliper body and conveyed outside by the at least one conveying channel through the at least one ventilation opening.

A vehicle brake system is provided that includes (or is formed from) a back plate configured to support a composite pad, at least one conditioning insert coupled to the back plate and configured to contact a surface of a wheel during a braking event and thereby to condition at least a portion of the surface of the wheel, and fins coupled with the at least one conditioning insert and configured to conduct heat generated by contact of the at least one conditioning insert with the at least the portion of the surface of the wheel away from the at least one conditioning insert.

A block for wheel brakes comprising a friction portion, in which a friction surface is defined, which, in use, acts upon a peripheral surface of a wheel in order to carry out the braking action, a support plate, which is fixed, in an irreversible manner, to a surface of the friction portion opposite the friction surface, and a base plate, which is fixed to the support plate and comprises a coupling element to fix the block as a whole to a brake system. The block comprises at least one elastic element placed between the support plate and the base plate. The presence of the elastic element creates a ventilation air space between the support plate and the base plate.
