Title: Lorry with a steered leading axle and trailing axle
Inventor: WINSAUER ERNST
IPC: B62D15/00
Filed: 1981-06-03
Abstract: The invention relates to a lorry with a steered leading axle and trailing axle. The object of the invention is to propose a device which, when a lorry is reversing, ensures without additional manoeuvres that, then also, the leading axle or trailing axle follows the steering lock of the steered front axle. The solution of the object consists in the fact that when the reverse gear of the vehicle is engaged, a switch is actuated which activates a control device which is acted on by the instantaneous degrees of steering lock of the front axle and of the leading or trailing axle and which acts on drives which steer the leading or trailing axle in accordance with the degree of steering lock of the leading axle. The advantage of the arrangement according to the invention is that it can be used for forward travel and reverse travel; a lower degree of wear of the tyres results and the wheel becomes a steered guide wheel.
