Abstract:
Die Erfindung betrifft eine Getriebe-Antriebseinheit (10), mit einem antriebsseitigen, in einem Getriebegehäuse (15) drehbar angeordneten Getriebeelement (11), mit dem ein Antriebsdrehmoment auf wenigstens ein Mitnahmeelement (25, 26) eines abtriebsseitigen Kupplungselements (20) übertragbar ist und mit einer Lastdrehmomentsperre, mit der ein von dem abtriebsseitigen Kupplungselement (20) über das wenigstens eine Mitnahmeelement (25, 26) eingeleitetes Drehmoment sperrbar ist, wobei die Lastdrehmomentsperre ein vorzugsweise als Schlingfeder ausgebildetes Sperrelement (42) aufweist, das zum Sperren des Drehmoments mit einem eine Reibfläche (51 ) aufweisenden, im Getriebegehäuse (15) drehfest angeordneten Bremselement (34; 34a; 34b) zusammenwirkt. Erfindungsgemäß ist es vorgesehen, dass das Bremselement (34; 34a; 34b) aus mehreren Blechelementen (48, 49; 57, 58; 57b; 58b) besteht und, dass die Blechelemente (48, 49; 57, 58; 57b; 58b) miteinander verbunden sind.
Abstract:
The subject matter described herein is directed to a brake drum (402) with a friction liner. The brake drum (402) includes an outer shell (404) and a friction liner (302). The outer shell (404) is formed from a first material such as a metal alloy. The friction liner (302) is formed from a functionally graded metal matrix composite (FGMMC) material. The brake drum (402) produced by the method described herein is economical and easy to manufacture. Also, due to an increased volume fraction of ceramic particles present in the friction liner (302), better wear resistance and enhanced life of the brake drum (402) is achieved.
Abstract:
A brake drum that converts kinetic and potential energy into frictional heat without developing destructively high temperatures and provides such performance at a reduced weight with an increase in cooling effectiveness through the use of a squealer band positioned on the centerline of the drum braking surface along with axial cooling fins radiating therefrom and windows on the wraparound portion abutting mounting face.
Abstract:
The invention provides a lightweight brake drum (10) comprising a lightweight, tubular inner member (14) having a reinforcement wrapping retention pattern (e.g., groove) cast in the exterior surface thereof, a length of reinforcement material (e.g., wrapped wire, cable, mesh, fibers, etc.) (16) in communication with a reinforcement retention pattern (e.g., a groove around the inner member) (14), the drum including an outer shell (18). The inner member (14) and the outer shell (18) are made of lightweight materials. Single, or multiple layers of reinforcement material (e.g. wrapping) are applied (e.g., wrapped) around the inner member (14) to support and inhibit expansion of the inner member (14). Because the reinforcement material (16) provides support against expansion, the inner member (14) and the outer shell (18) can be made of lightweight materials. In preferred embodiments, a bonding layer (66) is applied to the exterior surface of the inner member prior to application of the reinforcement material thereon. In preferred embodiments the reinforcement material comprises a low-impedance material such as copper along with another material that has good tensile strength characteristics (e.g., steel, composite fibers, Basalt-fibers, etc.). Preferably, the inner member comprises at least one material selected from the group consisting of a aluminum-based metal matrix composite (MMC) with a particulate reinforcement, ceramic matrix composite (CMC), and carbon graphite foam.
