<p>PURPOSE:To heighten the carrying height for a trailer by having a piston rod for a driving actuator for a brake shoe penetrated in a central position on a cross section of the edge of an acceleration shaft in order to connect it with an brake arm. CONSTITUTION:A piston rod 9 of an actuator 8 for driving a brake shoe 6 is penetrated in a central position on a cross section of the edge of a lower acceleration shaft 2 by a bush B that is welded at the same position, and is connected with a brake arm 10. The brake shoe 6 is actuated by the actuation of the actuator 8. Since the piston rod 9 is penetrated at the edge of the lower acceleration shaft 2 and in the center of the cross section, the strength of the lower acceleration shaft 2 is the same as it was before the penetration. The carrying height can thus be heightened without braking the lower acceleration shaft 2, and the ground height can also be heightened.</p> |
