Title: SEQUENTIAL GEAR SHIFTER
Abstract:
A sequential gear shift system (200) for two-way operated speed change gear units (4) of manually propelled vehicles. Mirrored, spaced-apart lever operators (35, 60), provided with increasing lever stroke ratio, and actuating sequentially and by means of independent hydraulic operation an actuator (1), with twin mirrored one-way multi-tooth rack-clutch mechanisms (84, 114), rapidly engaging with a shift element (33) and converting linear torque into circumferential, sequentially rotating said element in diametrically opposite directions and disengaged from said element when returning to normal. The actuator housing (8) and load bearing axle (17) of the speed change gear hub (4) are selectively, releasably, coaxially interconnected into a rigid gear system load bearing axle (29), combined at any angle, and shift direction is selectively reversible.
