  • the present invention relates to an actuator, a cab tilt device which comprises the actuator, a vehicle provided with an actuator and/or a cab tilt device, and a method for controlling an actuator.
  • Linear actuators are currently used to effect linear movements in very many applications.
  • a hydraulic linear actuator uses hydraulic power to provide mechanical linear motion.
  • Another type of actuator is a pneumatic linear actuator which converts compressed air to mechanical linear motion.
  • An electric linear actuator converts rotary motion from a motor, e.g. a low-voltage DC motor, to mechanical linear motion.
  • a linear actuator makes it possible, by simply pressing a button, to lift, adjust, tilt, push or pull objects which are heavy or difficult to access.
  • An electric linear actuator usually has a motor, a gear housing and a piston rod.
  • a screw e.g. a ball screw or worm screw, is rotated and the rotation is converted to linear motion by the piston rod.
  • the piston rod may for example run in a cylinder or casing.
  • the whole actuator may be surrounded by a casing, depending on the particular application and on protection requirements.
  • An example of an application for a linear actuator is truck cab tilting. There is sometimes a need to be able to tilt a truck cab in order to gain access to systems situated under the cab. There are currently various ways of achieving this function.
  • An actuator with a hydraulically activated piston may for example be connected to the chassis and the cab.
  • Cab and chassis being connected together by a springing system thus leads to the tilt system having also to cater for relative movements between chassis and cab.
  • Hydraulic cylinders with a so-called "lost motion” state a state in which the cylinder and the piston can move relative to one another, are currently used, but this movement results in both wear of the system and disturbing noise in the cab.
  • EP0485724 A1 describes a hydraulic system for tilting a cab, which is connected by a combination of linear movement and rotation.
  • An accommodating element is provided with a recess which fits with an element on the cab. The motion between these elements may however result in wear of the system.
  • An object of the invention is to propose a actuator which can effect controlled rotating as well as linear movement of its piston rod and does in particular make it possible to tilt a vehicle cab.
  • an actuator which comprises a motor, a threaded rod, a nut unit, a piston unit and a casing.
  • the motor is arranged to drive the threaded rod via a gearbox.
  • the actuator comprises a first means on the nut unit and a second means on the casing which perform a first guiding function for the actuator, the first means being arranged to fit with the second means so that the nut unit follows a predefined first path determined by the first means and the second means when they are engaged with one another and the motor drives the threaded rod.
  • This first aspect results in an actuator which can effect controlled axial rotating of the nut unit and consequently also of the piston unit.
  • the actuator can therefore effect both a linear movement and a rotating about a centreline of the threaded rod. This may be usable in many applications and is achieved by simply activating the motor.
  • the first guiding function serves as a form of rotation limitation between the piston unit and the casing.
  • the casing may also take the form of a cylinder round the nut unit and the piston unit.
  • the predefined first path describes the movement required of the nut unit and/or the piston unit.
  • the actuator may comprise a third means on the nut unit and a fourth means on the piston unit which perform a locking function for the actuator.
  • the third means is arranged to fit with the fourth means so that the nut unit follows a predefined locking path determined by the third means and the fourth means to a state in which the piston unit is locked to the nut unit, when the nut unit follows the predefined first path.
  • the locking function is activated by simply activating the motor.
  • the locked state may also be called positive locking.
  • the actuator may also comprise a fifth means on the piston unit and a sixth means on the casing which perform a second guiding function for the actuator.
  • the fifth means is arranged to fit with the sixth means so that the piston unit follows a predefined second path determined by the fifth and sixth means when they are engaged with one another and the motor drives the threaded rod. The result is that the piston unit is caused to assume a desired behaviour, e.g.

  • the actuator is arranged to have its one end fastened to the vehicle's chassis and its other end to the vehicle's cab.
  • the cab tilt device further comprises a control unit and/or input unit arranged to activate the tilting of the cab.
  • This second aspect makes it possible to use a single component to take care both of connecting together the actuator and the cab and of tilting the cab.

  • internal disengagement guided by controlled axial rotating makes it possible to replace existing hydraulic devices by an electrical device which has less internal friction and therefore potentially generates less disturbing noise in the cab.
