Embodiment Construction

[0023] The present invention will now be described in detail with reference to the accompanying drawings, wherein the same reference numerals are used for the same or like parts throughout.

[0024] The present invention therefore relates to shift lever systems (see especially figure 1 , 4 and 5) which are used for shift-by-wire in a vehicle (preferably a truck), whereby the shift motion is transmitted from the shift lever 2 to the two shift wires 4, 6 which are transferred from the vehicle The location below the cab extends substantially horizontally and enters the vehicle gearbox. In the figures, the shift wire is arranged to extend through the corrugated boot.

[0025] The selector lever system comprises a selector lever 2, a spherical bearing 8 with a point of rotation C, and a first transmission chain 10 and a second transmission chain 12 about which the selector lever can move, the first transmission The chain and the second drive chain are adapted to be subjected to ...

Abstract

A gear lever system for wire gearchange of a vehicle, preferably a truck, adapted to conveying gearchange movements from the gear lever (2) to first and second gearchange wires (4, 6) which run substantially horizontally from a location under the vehicle's driving cab and into the vehicle's gearbox, which element comprises a gear lever (2), a spherical bearing (8) with a rotation point C about which said gear lever is movable and a first transfer link (10) and a second transfer link (12) which are adapted to being acted upon by gearchange movements imparted by the gear lever (2) and are situated close to the lower end of the gear lever. The first transfer link (10) is adapted to conveying a gearchange movement A, which is substantially at right angles to the vehicle's longitudinal direction, directly to said first gearchange wire (4), and the second transfer link (12) is adapted, via rotation of a vertical spindle (14), to conveying to said second gearchange wire (6) a gearchange movement B which is substantially parallel with the vehicle's longitudinal direction.

Description

technical field [0001] The invention relates to a gear lever system. In particular the invention relates to a shift lever system adapted to transmit a shift movement from a shift lever to a gearbox via two shift wires. Background technique [0002] Many vehicles with manual shifts, such as trucks, currently have a rod and chain system. A disadvantage of these systems is that the chain system takes up a relatively large amount of space under the vehicle. [0003] Document DE-19803607 relates to an embodiment of a shifting device, whereby the shifting movement is transmitted to the gearbox via a chain system. [0004] Implementing the shift using wires allows a solution that takes up less space than a chain system under the vehicle. The gears are operated by wires in a gearbox provided with two shift wires that engage the desired gear by moving in the longitudinal direction, usually by means of a shift servo, to a preset position. stalls. [0005] The object of the presen...
