Driveline on truck
First Claim
1. An articulated vehicle (1) comprising:
- a front element and a rear element which are pivotable about a steering linkage disposed between them,a distribution box which supplies power from an engine to a forward wheelshaft of the front element via a first shaft and to a rear wheelshaft of the rear element via a second shaft,characterised in thata differential is disposed between the first shaft and the second shaft,a detection means detects a steering angle v formed between the front element and the rear element,the detection means detects whether the steering angle v is greater than a predetermined steering angle v1,a brake is disposed relative to said differential in order to lock, or brake, the differential when the steering angle v is smaller than said predetermined steering angle v1,wherein the detection means takes the form of an operating arm of a valve, which operating arm is provided with a guide roller which bears upon an outer contour of a spindle of the steering linkage.

Abstract
A device and a method for engaging and disengaging a longitudinal differential (10) disposed between a forward wheelshaft (4) and a rear wheelshaft (5) of an articulated vehicle (1) which has a front element (2) and a rear element (3) pivotable about a steering linkage (6) disposed between them and which comprises a distribution box (9) which supplies power from an engine (7) to the forward wheelshaft (4) in the front element (2) via a first shaft (11) and to the near wheelshaft (5) in the rear element (3) via a second shaft (12), wherein the longitudinal differential (10) is disposed between the first shaft (11) and the second shaft (12), whereby a steering angle v formed between the front element (2) and the rear element (3) is detected by a detection means (25a) so arranged that the detection means (25a) causes a differential brake (20) for the longitudinal differential (10) to be kept locked, or braked, when the detection means (25a) detects a steering angle v which is smaller than a predetermined steering angle V1.

11. A method for engaging and disengaging a longitudinal differential disposed between a forward wheelshaft and a rear wheelshaft of an articulated vehicle which comprises:
-
a front element and a rear element which are pivotable about a steering linkage disposed between them and a distribution box which supplies power from an engine to a forward wheelshaft of the front element via a first shaft and to a rear wheelshaft of the rear element via a second shaft, characterised by comprising the following steps; the longitudinal differential being disposed between the first shaft and the second shaft, a steering angle v formed between the front element and the rear element being detected by a detection means, the detection means causing a differential brake for the longitudinal differential to be kept locked when the detection means detects a steering angle v which is smaller than a predetermined steering angle v1, and the detection means takes the form of an operating arm of a valve, which operating arm is provided with a guide roller which bears upon an outer contour of a spindle of the steering linkage. - View Dependent Claims (12, 13)
