Embodiment Construction

[0022] Figure 1 to Figure 3The selector mechanism shown in includes an elongated shaft divided into two parts 2, 4 along its length. Part 2 is connected to the piston rod of a four-position hydraulic actuator 6, which will be described below, and part 2 is also connected to part 4 through a connecting mechanism that does not allow relative movement in the longitudinal direction, but allows Axes 2, 4 length relative movement in a single transverse direction. To this end, part 4 has a bifurcated end 8 in which a hole is formed. The part 2 has a flat end which is received in the bifurcated end 8 and in which a slot 10 is formed. The stop pin 12 passes through the hole and the slot 10 of the bifurcated end 8 . Movement of pin 12 within slot 10 allows relative lateral movement between part 2 and part 4 .

[0023] The shaft portion 4 is longitudinally slidably mounted in a mount 14 connected to a bracket 16 . Part 4 rotatably supports a pawl in the form of an elongated rod 18 ...

Abstract

A gear selector mechanism for a twin clutch gearbox includes a shaft ( 2, 4 ) and a first actuator ( 6 ) arranged to move the shaft linearly parallel to its length The shaft ( 2, 4 ) is connected to a pivotal lever ( 18 ) carrying a selector finger ( 20 ) adapted to engage in a recess ( 44 ) in a selected gear selector rail ( 46, 48, 50, 52 ), a second actuator ( 24 ) and a return spring ( 22 ) cooperating with the pivotable lever. The second actuator ( 24 ) is arranged to pivot the lever ( 18 ) from an inoperative position, in which the selector finger does not engage in a recess in a gear selector rail, to an operative position, which the selector finger does engage in a recess in a gear selector rail. The return spring is arranged to move the lever from the operative position to the inoperative position. The second actuator ( 24 ) is carried by a carrier ( 16 ) which is connected to a third actuator ( 30 ) arranged to move the carrier ( 16 ) linearly in a direction transverse to the length of the shaft ( 2, 4 ). The shaft ( 2, 4 ) or its connection to the pivotable lever ( 18 ) is constructed to permit relative movement of the pivotable lever and the first actuator ( 6 ) in the direction of movement of the third actuator ( 30 ).

Description

technical field [0001] The present invention relates to gear selector mechanisms and to mechanisms for use with so called dual clutch gearboxes. The gearbox actually has two parallel torque paths, and the output and input of the torque paths are respectively connected to the output shaft and the input shaft of the gearbox through respective clutches. Only one clutch is engaged at any one time, which means torque is transmitted through one or the other of the torque paths. The selection of gears in the gearbox is mechanical, rather than manual, and while the gearbox operates in a certain ratio using one of the torque paths, the next ratio preferably cooperates with the other non-active torque path. When it is desired to change gears, the currently active clutch is no longer engaged, but another clutch is engaged and torque is transmitted through another torque path. Background technique [0002] Twin clutch gearboxes are well known, an example of such a gearbox is disclosed...
