ABSTRACT:
A parking brake in a transmission consists of a toothed wheel non-rotatably joined to the output shaft of the transmission and a pawl on an arm which is pivotally joined to the housing. The arm is pivotally mounted in a yoke which partially encircles the toothed wheel and is limitedly movably mounted in the housing on opposite sides of the output shaft. The yoke has abutment surfaces on diametrically opposite sides of the toothed wheel, and when the pawl engages the toothed wheel, the yoke will be displaced so that--depending on the direction in which the toothed wheel is loaded--one of the abutment surfaces comes into contact against the toothed wheel. This eliminates bending stresses on the shaft at the same time as the forces transmitted to the housing will be only a fraction of the force acting between the pawl and the toothed wheel, due to the difference in the length of the moment arms.
