A shift mechanism of a transmission having excellent vehicle mountability is provided. A shift mechanism 1 includes a case 10, a shift select lever shaft 60 accommodated in the case 10 and capable of shifting in an axial direction and moving rotationally in a circumferential direction, a first inner lever 40 engaging the shift select lever shaft 60 at a first engaging portion 62 within the case 10, coupled with an inertia mass 50, and moving rotationally about a first axis of rotational movement 44 between the inertia mass 50 and the first engaging portion 62, and a second inner lever 30 engaging the shift select lever shaft 60 at a second engaging portion 61 within the case 10, coupled with an outer lever 20, and moving rotationally about a second axis of rotational movement 24 between the outer lever 20 and the second engaging portion 61.

A transmission 103 equipped with a cable-type shift device comprises a control shaft 140 to control a shift change with rotation and axial-direction movement thereof, an outer lever 130 to be rotated by a shift-direction operation of a change lever 110, and a counterweight 150 to rotate with the rotation of the control shaft, but not to move with the axial-direction movement of the control shaft. The counterweight 150 includes first and second weight portions 151, 152, an arm portion 153 to interconnect these weight portions, and a support axis 154 disposed so as to extend vertically. The support axis 154 rotatably supports a substantial gravity center of the first and second weight portions and the arm portion. Accordingly, the counterweight can be supported smoothly and the shift feeling can be improved properly with a relatively small force for the select-direction operation of the change lever.

The invention relates to a shifting device for a multi-step tooth-wheeled variable-speed gear box in a motor vehicle. Said shifting device comprises a central selector or gear-shift shaft (2) which is arranged in a rotatable and axially displaceable manner in the gearbox housing (12). Rotation of the selector or gear-shift shaft (2) enables selection of a release clutch which is to be actuated in a shifting path. Due to the subsequent axial displacement thereof, gear-steps can be shifted. The selector or gear-shift shaft (2) comprises at least two arms (4) which are arranged at a certain distance from each other on said shaft and which maintain a rod (6) therebetween. The rod (6) interacts with a contour element (16) which is arranged in a pivotable manner in the gearbox housing (12). The contour element (16) comprises a contour (20) which reproduces the path of the selector force acting upon the rod (6) by means of a spring-loaded element (18).

A steer-by-wire gear shifter comprises: a holder (1); a rotary shaft (2) rotatably held by the holder; a shift lever (3) whose bottom is fixed on the rotary shaft; a shift knob (4) attached to a top of the shift lever; detecting means (5) for detecting an operational condition of the shift knob; an actuator (6) which applies an external force for force feedback to the shift knob through the rotary shaft and the shift lever; a control section (8) which receives a detection signal a from the detecting means, a transmission signal d from a transmission controller (7) and an engine revolution speed signal e from an engine controller, generates and outputs a control signal b for the actuator and a gear shift signal c for the transmission controller; and a release switch which unlocks the shift knob.

Es wird vorgeschlagen eine Gangwechselvorrichtung (30) für ein handschaltbares Getriebe (16) eines Kraftfahrzeuges (10), mit einem Gangwechselhebel (32), der in einem H-Gangwechselschema (34) mit einer Wählgasse (44) und wenigstens drei Schaltgassen (36-42) beweglich ist und von einem Führer des Kraftfahrzeuges (10) betätigbar ist, einer Schalteinrichtung (52, 56), die mit dem Gangwechselhebel (32) mechanisch gekoppelt ist und dazu dient, Schaltbewegungen (S) des Gangwechselhebels (32) innerhalb der jeweiligen Schaltgassen (36-42) zu dem Getriebe (16) zu übertragen, einer Wähleinrichtung (52, 54), die mit dem Gangwechselhebel (32) mechanisch gekoppelt ist und dazu dient, Wählbewegungen (W) des Gangwechselhebels (32) innerhalb der Wählgasse (44) zu dem Getriebe (16) zu übertragen, und einer Rückstelleinrichtung (58), die den Gangwechselhebel (32) innerhalb der Wählgasse (44) in eine zentrale Wählposition (48) elastisch vorspannt, die einer mittleren (38) der wenigstens drei Schaltgassen (36-42) zugeordnet ist. Dabei ist die Rückstelleinrichtung (58) asymmetrisch ausgelegt ist, derart, daß einer Wählbewegung (W) des Gangwechselhebels (32) aus der zentralen Wählposition (48) je nach Wählrichtung eine andere Gegenkraft (F) entgegenwirkt.
