Abstract

L'invention concerne un frein à tambour comportant deux mâchoires 11, 12, montées sur un plateau de frein de façon à pouvoir être appliquées contre un tambour rotatif et dans lequel le jeu entre les garnitures 13 des mâchoires et le tambour est maintenu constant par un dispositif de réglage automatique. Le dispositif de réglage automatique comprend une entretoise 19 qui s'étend entre les deux mâchoires et un dispositif de verrouillage unidirectionnel 22 qui permet à la longueur utile de l'entretoise de s'accroître mais non de diminuer. Le dispositif 22 est constitué par une pince élastique qui comprend deux bras qui sont en prise sur les côtés diamétralement opposés à la nervure 20 de l'une des mâchoires 12. L'invention est applicable, notamment, aux freins de véhicules automobiles.The invention relates to a drum brake comprising two shoes 11, 12, mounted on a brake plate so that they can be applied against a rotating drum and in which the clearance between the linings 13 of the jaws and the drum is kept constant by a automatic adjustment device. The automatic adjustment device comprises a spacer 19 which extends between the two jaws and a one-way locking device 22 which allows the effective length of the spacer to increase but not to decrease. The device 22 is constituted by an elastic clamp which comprises two arms which are engaged on the diametrically opposite sides to the rib 20 of one of the jaws 12. The invention is applicable, in particular, to the brakes of motor vehicles.
