Abstract

é fornecido um freio de tambor que melhora a direção das forças de acionamento para reduzir o estresse, melhorar a eficiência e permitir lonas de freio mais espessas. as primeira e segunda sapatas de freio têm, cada uma, uma primeira extremidade acoplada de forma articulada aos mesmos ou diferentes pinos de ancoragem em uma aranha de freio. primeiro e segundo seguidores de came estão localizados em segundas extremidades correspondentes das sapatas de freio. um came se acopla aos seguidores de came com movimento do came, fazendo com que as sapatas de freio se movam entre posições de acoplamento e desacoplamento com uma superfície de frenagem. os seguidores de came são deslocados, de modo que as distâncias entre os centros dos primeiros seguidores de came e ou os pinos de ancoragem que suportam as sapatas de freio diferem, de modo a melhorar a direção do vetor de força do came.
