Abstract

Unidad de freno de tambor para vehículo. Medios para resolver los problemas: Un extremo (55a) de un muelle helicoidal (55) que empuja un brazo de freno (53) en la dirección que libera el freno, apoya en una posición hacia la porción de punta (53a), entre el centro de oscilación (66) y la porción de punta (53a) del brazo de freno (53), y el otro extremo (55b) del muelle helicoidal (55) apoya sobre la carcasa de freno (52), introduciéndose en el muelle helicoidal (66) una varilla (56) para restringir la inclinación del muelle helicoidal en la dirección longitudinal. Efectos: Se puede usar un muelle helicoidal que tiene una longitud helicoidal larga. Como resultado, se puede usar un muelle helicoidal de un costo relativamente bajo, por lo que es posible evitar el aumento del costo de producción de la unidad de freno de tambor.Drum brake unit for vehicle. Means for solving the problems: One end (55a) of a coil spring (55) that pushes a brake arm (53) in the direction that releases the brake, rests in a position towards the tip portion (53a), between the oscillation center (66) and the tip portion (53a) of the brake arm (53), and the other end (55b) of the helical spring (55) rests on the brake housing (52), entering the helical spring (66) a rod (56) to restrict the inclination of the coil spring in the longitudinal direction. Effects: A helical spring having a long helical length can be used. As a result, a relatively low cost coil spring can be used, so it is possible to avoid increasing the production cost of the drum brake unit.
