An operating device for a differential lock in a vehicle

Abstract

An operating device for a differential lock in a vehicle (1) wherein the operating device (10) comprises a separate connecting means (14) which is movable relative to a driving shaft (6) in its axial direction but fixed in its rotational direction, and a second connecting means (16) which is fixed relative to a second driving shaft (8) in its axial direction, and wherein the differential lock is engaged by a mechanically firm connection being effected between the two connecting means (14, 16) by the latter being brought into engagement with one another by means of a operating fork (32) which has two limbs (52, 54) adapted to fitting in a groove (56) of the separate connecting means (14), and wherein the proximal ends (64, 66) of the limbs (52, 54) are connected to one another via a body (50), the distal ends (68, 70) of the limbs (52, 54) are bent inwards towards one another and the distal ends (68, 70) of the limbs (52, 54) are arranged at a distance (C) from one another which is smaller than cross- sectional diameter (D) of the portion of the separate connecting means (14) which is bounded by the bottom surface (64) of the groove (56) in which the connecting means (14) is retained in the operating fork (32) by limbs (52, 54).

Description

technical field [0001] The invention relates to an actuating device for a differential lock in a vehicle. Background technique [0002] Vehicles usually have a differential gear between the two drive wheels. The differential gear makes it possible for the drive wheels to run at different speeds, for example when navigating a bend, and at the same time it distributes the same drive power to both drive wheels. On vehicles with more than two drive wheels, there may also be differential gears on each drive shaft between the front and rear drive shafts. When, for example, driving off-road or on a surface in a slippery position, it is desirable to reduce or completely eliminate the differential effect so that a drive wheel on a drive shaft does not slip and another drive wheel on the same drive shaft stops applying its impetus. The differential effect of the differential gear can be reduced or completely eliminated by using the differential lock. On heavy vehicles, such as tru...

Problems solved by technology

[0005] According to the invention, the necessity to securely lock the independent coupling means in the manipulating fork by means of one or more screws or rivets before dismounting or installing the drive shaft on which the independent coupling means are arranged is solved by the manipulating device of claim 1 in order to avoid the problem of the independent linkage moving out of the steering fork
