ABSTRACT:
The invention relates to a protective device of drum-brake operating shafts of trucks and touring trailers. This device is essentially constituted by a protective sleeve (4) mounted on the bushing (5) of the operating shaft (1) of the clearance cam (3) of the brake shoes. This sleeve (4), extended up to the operating lever (2), comprises a packing (6) at each one of the extremities of its bore. The axis of the bore (4d) is upwardly offset in relation to the axis of the sleeve (4), of a distance X corresponding to one half of the clearance arranged between the shaft (1) and the bore (4d). A sectoral wearing plate (10) is disposed at the lower portion of the bore (4d). The sleeve (4) is mounted at the connecting bridge (8) by an annular collar (4a) with an indexing key (4b) and of the housing (9), existing at the beginning, or of a tab molded with the sleeve (4).
