Abstract

841,798. Change-speed control. TATRA NARODNI PODNIK. Sept. 8, 1958, No. 28809/58. Class 80 (2). In order to reduce the effort required to change gear in a synchro-mesh gear-box, a main shaft 1 of the shift mechanism is formed with a cam collar 13 engaged by spring-loaded fol.- lower rollers 15 which, when the shaft is moved from its neutral position (shown) engage a flank of the collar and apply an axial thrust to the shaft to assist engaging a gear. The shaft 1 actuates a shift fork 3 actuating a dog clutch sleeve 7 which is coupled to a synchro-mesh friction cone 10 by a spring-loaded ball 8 engaging a recess in the sleeve 7. The shift fork 3 is held in selected positions by a spring-loaded ball detent 4.
