发明名称 COMBINED SHIFT CONTROL
摘要 <p>COMBINED SHIFT CONTROL A combined shift control for a change speed gear transmission and a two-speed axle for motor vehicles, whereby, for instance, a five speed gear box with one reverse gear is extended to provide a seven speed gear box with one reverse gear. The gear box includes three parallel shift rods (12, 13, 14) each carrying a respective selector block (15, 16, 17). The slot (18) of the fourth/fifth selector block (17) is is deeper than usual so that the gear lever (21) can operate it in two different transverse positions. In one position the gear lever (21) actuates the fourth and fifth gears, but in the second position, after overcoming a spring-loaded plunger (20) and operating two micro-switches (24) which serve to change the axle ratio to a higher value, the gear lever (21) effectively actuates two further gears (sixth/seventh) when selector block 17 is caused to move the shift rod 14 to engage fourth and fifth gears again. In order to retain the gear lever (21) in the high axle ratio position when the driver lets go of the lever means such as a slidable gate (22) which is locked into position when the higher axle ratio is selected via the micro-switches (24) are provided. Alternate forms of switch and retaining means are described with reference to other Figs. An embodiment is disclosed (Figs. 12, 13) for use with a selector finger mounted on a cross shaft rather than a pivotable gear lever of Fig. 4.</p>
