A brake drum for a vehicle includes a friction ring and a drum body. The friction ring has grooves arranged on a radial outer surface along a circumference, and a coating formed on the grooves. The drum body is cast onto the radial outer surface of the friction ring so that the grooves are filled with a material of the drum body. The grooves include first grooves and second grooves. A first axial segment is formed at the friction ring in which the first grooves are introduced so that the first grooves are inclined relative to a first axial end of the friction ring. A second axial segment is formed at the friction ring in which the second grooves are introduced so that the second grooves are inclined in a direction which is opposite to that of the first axial segment. Each of the grooves have undercuts.

Brake drum and method for producing such a brake drum

A device for producing a cylinder crankcase using a low-pressure casting method or a gravity casting method. The device includes an outer casting mold which includes at least one mold part which, in an assembled state, forms a mold cavity that reproduces, for casting purposes, an outer contour of the cylinder crankcase. A region of the mold cavity forms a cylinder space of the cylinder crankcase. A dosing furnace contains a liquid metal. At least one gate is arranged geodetically below the mold cavity and via which the dosing furnace can be fluidically connected to the mold cavity. Sprue bushings project into the region of the mold cavity that forms the cylinder space of the cylinder crankcase. Each of the at least one gate is connected to one of the sprue bushings.
