Embodiment Construction

[0072] figure 1 A measuring unit assigned to one of the wheels of the vehicle is shown in each case with reference numerals 1 and 2 . It can be seen that the measuring units are assigned to the wheels of the different steerable axles A1 and A2 on different sides of the vehicle.

[0073] Measuring units 1 and 2 each detect the individual track angles of the associated wheels.

[0074] An adjustment device for adjusting the directions of travel δA1 and δA2 of the two steerable axles A1 and A2 relative to one another is marked with reference numeral 3 .

[0075] Under the premise that the total wheelbase values ​​GSpA1 and GSpA2 of the axles A1 and A2 remain unchanged during adjustment or the change of the total wheelbase value is negligible, it can be concluded from the above deduction that: from the wheelbase value SpA1 左 The measurement and wheelbase value of SpA2 右 The measurement of can be adjusted to achieve a value Δ that is numerically smaller than the threshold value....

Abstract

The invention relates to a device and to a method for measuring and determining relevant parameters for the adjustment of the directions of travel of two steerable axles of a vehicle in relation to each other, wherein only one measuring unit for measuring the individual toe angle of a wheel associated with said measuring unit is present on each vehicle side in such a way that a first measuring unit is associated with the wheel of the first of the steerable axles on the left vehicle side and the second measuring unit is associated with the wheel of the second of the steerable axles on the right vehicle side, wherein the output signals of the measuring units are fed to an evaluating unit, wherein the difference of the directions of travel of the two steerable axles or a parameter representing said difference is determined in the evaluating unit from the fed signals of the measuring units and is provided as an output signal of the evaluating unit. The invention further relates to a method for adjusting the directions of travel of two steerable axles of a vehicle in relation to each other, wherein the adjustment of the directions of the two steerable axles in relation to each other is performed by means of only one measuring unit per vehicle side, in that the difference of the directions of travel of the two steerable axles or a parameter representing said difference is determined from a measurement of the toe angle of the right wheel of a first of the two axles and the measurement of the toe angle of the left wheel of the second axle, wherein the adjustment of the directions of travel of the two steerable axles in relation to each other is performed in such a way that the difference or the parameter representing said difference is smaller in magnitude than a threshold value.

Description

technical field [0001] The invention relates to a device and a method for adjusting the direction of travel of two steerable axles of a vehicle relative to each other according to the preamble of claims 1 and 5 . Background technique [0002] The purpose of the chassis adjustment of a vehicle with two steerable axles ( A1 , A2 ) is that, in a horizontal steering wheel position, the direction of travel of the steerable axles coincides with the axis of travel of the vehicle. Vehicles with two steerable axles are, for example, trucks for transporting heavy goods. The travel axis is defined by the direction of travel of the rear axles. In this case, the chassis geometry of the vehicle can be measured using the device and method of document DE 10 2008 045 307 A1. As a result of the chassis measurements and as a result of the detection of the steering wheel angle Ω (difference of the steering wheel to the horizontal) of the vehicle for the two steerable axles A1 and A2, four sin...
