PERFEZIONAMENTO NEI CAMBI DI MARCIA PER TRASMISSIONI DI AUTOVEICOLI PARTICOLARMENTE DEL TIPO BLOCCABILE CON IL BLOCCAGGIO DEL PIANTONE DEL LO STERZO

摘要

A transmission shift control mechanism has a pivotally mounted shift lever and bracket on which is pivotally mounted a lock pawl. A lock lever is pivotally mounted on the same axis as the shift lever and bracket and has an abutment surface thereon which is maintained in contact with a cam surface on the lock pawl. The shift lever and bracket and the lock lever are operatively connected by a spring. The lock lever is connected to the vehicle steering column by a cable mechanism such that the lock lever is maintained stationary when the steering column is locked whereupon pivotal movement of the shift lever and bracket results in relative movement between the lock pawl and abutment surface causing engagement between the lock pawl and the stationary latch member whereby further pivoting of the shift lever and bracket is prevented.
