Description

Technical Field

[0008] , ,

[0001] The present invention relates to a ventilated brake rotor and a ventilated type brake, and in particular, is not limited to applications in the field of automobiles, such as the field of drum-in-hat brakes.

Background Art

[0002] In a ventilated type brake, depending on whether it is a disc brake or a drum brake, the bell of the brake disc, the rotating drum, or the fixed jaw holder plate of the drum brake constitutes a ventilation part that allows the passage of an air flow that increases the heat exchange of the vehicle's brake and accelerates the cooling process.

[0003] The ventilation part is generally a part of the drum, the fixed plate, or the bell that constitutes a through ventilation opening.

[0004] Such openings are usually arranged circumferentially so that the turbulent air movement that accelerates the cooling of the brake is caused inside the bell or the drum.

[0005] Instead, when such openings are obtained on the fixed plate of the drum brake, they are usually in the form of ventilation windows and / or ventilation holes.

[0006] It has been found that in certain situations of vehicle running, in addition to air, solid foreign objects can also pass through such ventilation openings and be trapped in the drum interior or the gap between the bell and the wheel hub.

[0007] In particular, foreign objects passing through the ventilation openings can, in addition to affecting cleanliness, damage internal components of the brake, such as components of the ABS system, bearings, and, for example, drum parking brakes housed inside the bell of a drum brake or a disc brake of a commercial vehicle. [[ID=3,4]]<\\

[0008] Furthermore, foreign objects such as pebbles can become trapped inside the ventilation pipe, obstructing airflow and impairing brake cooling.

[0009] Furthermore, the trapping of foreign objects inside the rotating parts of the brakes can become a source of noise, causing inconvenience to vehicle users and road users.

[0010] Because components located inside ventilated drums or bells experience increased wear compared to components located inside non-ventilated drums or bells, vehicles with ventilated bells or drums have been found to have higher maintenance costs than vehicles with non-ventilated bells or drums.

[0011] Prior art is known for ventilated drum brakes for racing motorcycles manufactured between 1960 and 1980 by companies such as Ceriani, Fontana, and Oldani, which feature a fixed jaw holder plate with a large ventilation window facing the direction of travel and multiple axial ventilation openings. In such brakes, the ventilation window is covered with a perforated metal sheet, and the axial opening It has no cover.

[0012] Such ventilated drum brakes include perforated covers positioned over the ventilation windows, thus preventing foreign matter from entering the drum brake, but only partially overcome the aforementioned problem by leaving the axial ventilation openings unprotected. Therefore, foreign matter can still enter through the axial ventilation openings.

[0013] Furthermore, in addition to only partially overcoming the aforementioned problems, such solutions relate exclusively to ventilated brakes that have ventilation openings in the fixed portion of the drum brake.

[0014] Therefore, there is a strong need to provide a ventilated brake rotor that can overcome the shortcomings known from prior art without compromising not only cooling performance but also operating performance.

[0015] Furthermore, there is a perceived need to obtain a simple ventilated rotor with as few components as possible, which can be manufactured inexpensively and / or easily from already commercially available ventilated brakes at the lowest possible cost.

[0016] In particular, there is a perceived need for ventilated brake rotors for vehicles that offer exceptional durability on the one hand, and reduce brake maintenance on the other.

[0017] Therefore, the fundamental problem of the present invention is to devise a ventilated brake rotor and brake that have structural and functional features that satisfy the aforementioned needs, while avoiding the drawbacks described by reference to the prior art. [Overview of the Initiative]

[0018] The object of the present invention is to provide a ventilated brake rotor that serves to protect vehicle or brake components located near the ventilated rotor.

[0019] The object of the present invention is to obtain a ventilated brake rotor in which the possibility of foreign matter entering the ventilation opening is reduced and cooling characteristics are maintained, using a solution that can be implemented as simply and easily as possible in the manufacturing steps.

[0020] This objective and other objectives and advantages are achieved by the ventilated brake rotor according to claim 1, the brake according to claim 9, and the vehicle according to claim 11.

[0021] Several advantageous embodiments are the subject of the dependent claims.

[0022] The proposed solution maintains very high brake rotor cooling efficiency.

[0023] Furthermore, the proposed solution prevents access of foreign objects with respect to at least one ventilation opening by providing only one additional Protective material while leaving the passage free for cooling fluid purposes.

[0024] Protective material has a thickness smaller than the thickness of the cup-shaped body of the ventilated rotor where the ventilation opening is obtained and forms a ventilation pipe having a length substantially equal to the thickness of the cup-shaped body of the ventilated brake rotor.

[0025] Also here, Protective material is made as a separate part with respect to the cup-shaped body of the ventilated brake rotor.

[0026] Furthermore, Protective material is removably detachable from the cup-shaped body of the rotor and thus, Protective material can be easily cleaned, disassembled, reassembled or replaced during maintenance of the ventilated brake.

[0027] Furthermore, Protective material is annular Protective material and due to its shape which is complementary to the cup-shaped body part, it is connected to and constrained by the cup-shaped body without using additional fixing elements.

[0028] Furthermore, the proposed solution makes it possible to obtain a ventilated rotor without introducing a time-consuming and complex assembly operation.

[0029] Further features and advantages of the ventilated brake rotor, the brake and the vehicle will become apparent from the following description of its preferred embodiments, given as non-limiting examples with reference to the accompanying drawings.
