Abstract
A truck has a driver's cab tiltably mounted above a drive train and coupled in an articulated fashion to a bottom chassis by a bearing. The drive train is attached to the chassis, and has a restraint system for the driver's cab. In the case of a head-on collision of the truck with an obstacle at the level of the driver's cab, the restraint system serves to absorb and deflect collision forces at the driver's cab. The restraint system includes a flexible coupling element that establishes a connection, which is resistant to tensile stress counter to the direction of travel, between the driver's cab and a front fixed part of the drive train located underneath it.
Claims15
A truck comprising:
- a driver's cab that is tiltably mounted above a drive train attached to a bottom chassis and coupled in an articulated fashion to said bottom chassis by a bearing,
- a restraint system for the driver's cab operating, during head-on collisions of the truck with an obstacle at the level of the driver's cab, to absorb and deflect collision forces at the driver's cab,
- wherein the restraint system comprises a flexible coupling element secured to an end region of a drive engine that establishes a connection, resistant to tensile stress counter to the direction of travel, between the driver's cab and a front fixed part of the drive train located underneath the driver's cab, and
- wherein the flexible coupling element permits free tilting of the driver's cab about the bearing so that, in an operating state, a possibility of the driver's cab tilting and an intrinsic mobility of the driver's cab and of the drive train is unaffected by the flexible coupling element.
