Abstract
Eine Bremsbaugruppe zur Verwendung in einem Scheibenbremsmechanismus eines Fahrzeugs. Die Bremsbaugruppe umfasst einen Rotor aus Aluminium-Keramik-Verbundwerkstoff, der mit einer zentralen Aluminiumnabe verbunden ist. Der Rotor schließt Vorsprünge ein, die sich radial nach innen in Richtung der Nabe erstrecken und mit Durchgangslöchern in der Nabe in Eingriff stehen. Die Vorsprünge erstrecken sich durch die Durchgangslöcher, um den Rotor mit der Nabe zu verbinden. Der Eingriff zwischen den Vorsprüngen und den Durchgangslöchern ermöglicht eine radiale Bewegung der Vorsprünge relativ zu den Durchgangslöchern, wobei die radiale Bewegung durch Wärmeausdehnung des Rotors aufgrund von Wärme verursacht werden kann, die während eines Bremsvorgangs erzeugt wird.A brake assembly for use in a vehicle disc brake mechanism. The brake assembly includes a rotor made of aluminum-ceramic composite, which is connected to a central aluminum hub. The rotor includes protrusions that extend radially inward toward the hub and engage through holes in the hub. The protrusions extend through the through holes to connect the rotor to the hub. The engagement between the projections and the through holes allows the projections to move radially relative to the through holes, the radial movement being caused by thermal expansion of the rotor due to heat generated during braking.
Description
HINTERGRUNDBACKGROUND
Bremsrotoren aus Aluminium-Keramik-Verbundwerkstoff sind zur Verwendung in Fahrzeugen als Teil eines Scheibenbremsmechanismus bekannt. Im Vergleich zu Bremsrotoren auf Eisenbasis sind Bremsrotoren aus Aluminium-Keramik-Verbundwerkstoff leichter, wodurch das Gesamtgewicht des Fahrzeugs verringert wird und Einsparungen bei den Kraftstoffkosten erzeugt werden. Jedoch können diese Rotoren aus Aluminium-Keramik-Verbundwerkstoff nicht an eine Metallnabe geschweißt werden und stellen daher Herausforderungen dar, wenn der Rotor an einer Metallnabe und an einer Achse eines Fahrzeugs angebracht wird.Brake rotors made of aluminum-ceramic composite are known for use in vehicles as part of a disc brake mechanism. Compared to iron-based brake rotors, aluminum-ceramic composite brake rotors are lighter, reducing the overall weight of the vehicle and saving fuel costs. However, these aluminum-ceramic composite rotors cannot be welded to a metal hub and therefore pose challenges when the rotor is attached to a metal hub and an axle of a vehicle.
Außerdem erfahren diese Bremsrotoren aus Aluminium-Keramik-Verbundwerkstoff eine gewisse Wärmeausdehnung aufgrund der Wärme, die aus der Reibung während eines Bremsvorgangs erzeugt wird. Diese Wärme verursacht, dass die Rotoren aus Aluminium-Keramik-Verbundwerkstoff sich mit einer unterschiedlichen Geschwindigkeit/Menge als die Metallnabe ausdehnen und zusammenziehen, aufgrund von Unterschieden in den Koeffizienten der thermischen Ausdehnung der beiden Materialien. Der Unterschied in der Wärmeausdehnung kann auch daraus resultieren, dass die Nabe während der Bremsvorgänge nicht der gleichen Wärmemenge wie die Rotoren ausgesetzt wird, da die Nabe während der Bremsvorgänge keine Reibung erfährt. Solch ein Unterschied in der Ausdehnung zwischen den Rotoren aus Aluminium-Keramik-Verbundwerkstoff und den Metallnaben muss beim Verbinden der beiden Bauteile berücksichtigt werden, was eine weitere Herausforderung bei der Verwendung von Rotoren aus Aluminium-Keramik-Verbundwerkstoff darstellt.In addition, these brake rotors made of aluminum-ceramic composite experience a certain amount of thermal expansion due to the heat generated from the friction during a braking operation. This heat causes the aluminum-ceramic composite rotors to expand and contract at a different rate / amount than the metal hub due to differences in the coefficients of thermal expansion of the two materials. The difference in thermal expansion can also result from the fact that the hub is not exposed to the same amount of heat as the rotors during braking, since the hub does not experience any friction during braking. Such a difference in expansion between the aluminum-ceramic composite rotors and the metal hubs must be taken into account when connecting the two components, which is another challenge when using aluminum-ceramic composite rotors.

Nach einem Gesichtspunkt der vorliegenden Erfindung, schließt eine Bremsbaugruppe einen Bremsrotor und eine Nabe ein. Der Bremsrotor hat eine Drehachse und schließt eine zentrale Öffnung und Vorsprünge ein, die sich radial nach innen in Richtung der Achse erstrecken. Die Nabe ist innerhalb der zentralen Öffnung angeordnet und schließt Durchgangslöcher ein, die um einen Umfang der Nabe beabstandet sind. Die Vorsprünge sind in den Durchgangslöchern angeordnet, um dadurch den Rotor mit der Nabe zu verbinden. Die Vorsprünge können sich in Bezug auf die Durchgangslöcher radial bewegen, ohne den Rotor von der Nabe zu trennen.In one aspect of the present invention, a brake assembly includes a brake rotor and a hub. The brake rotor has an axis of rotation and includes a central opening and protrusions that extend radially inward toward the axis. The hub is disposed within the central opening and includes through holes that are spaced around a circumference of the hub. The protrusions are arranged in the through holes, thereby connecting the rotor to the hub. The protrusions can move radially with respect to the through holes without separating the rotor from the hub.

DETAILLIERTE BESCHREIBUNGDETAILED DESCRIPTION
Eine Bremsbaugruppe schließt einen Rotor und eine Nabe ein. Der Rotor schließt eine Vielzahl von Vorsprüngen ein, die sich in Durchgangslöcher in der Nabe erstrecken. Diese Durchgangslöcher greifen in die Vorsprünge so ein, dass ein Entfernen des Rotors von der Nabe verhindert wird, aber eine thermische Ausdehnung des Rotors (radial nach innen) möglich ist, wenn der Rotor in Betrieb ist und erhöhten Temperaturen ausgesetzt ist.A brake assembly includes a rotor and a hub. The rotor includes a plurality of protrusions that extend into through holes in the hub. These through holes engage the protrusions so that removal of the rotor from the hub is prevented, but thermal expansion of the rotor (radially inward) is possible when the rotor is in operation and exposed to elevated temperatures.
