Stable equipment, cab tipping device, a vehicle and a method for controlling a stable deviceAreas of inventionThe dangerous technology refers to a stable device, a cab tilting devicecomprising the stable device, a vehicle comprising a stable device and / or oncab tilting device, as well as a method for controlling a stable device.
Background of the inventionLinear stables are used today to perform linear movements in very many waysapplications. A hydraulically linear stable unit uses hydraulic power toachieve a mechanical lines movement. Another type of stable is pneumatic linear stable that converts compressed air into a mechanical linear motion. An electric line actuator converts a rotating object from a motor, for example a lawful DC motor, into a mechanical line object. A linear stable does itpossible to lift, adjust, tilt, push or pull heavy or hard-to-reach objectsjust by pressing a button.
An electrically linear stable usually has a motor, a gear housing and a piston rod. A screw, such as a ball screw or snack screw, is rotated and rotatedtransferred to a linear arrangement of the piston rod. The piston rod can, for example, run in onecylinder or tail. The entire stable can be surrounded by a shell depending on the application and protection needs.
An example of an application for a linear stable device is tipping of truck cabins.
However, there is sometimes a need to be able to tip the cab to get access to themsystems mounted under the cab. There are different salts to solve this function on. today. For example, a stable unit with a hydraulically actuated piston can be connected to the chassis and the cab. As the cab and chassis are connected to a resilient system, this leads to the tipping system also having to handlerelative movement between chassis and cab. Today, hydraulic cylinders with a saw are usedcalled "lost motion" Idge, an Idge dal 'cylinder and piston can move relatively2each other. However, this movement gives rise to both wear and tear of the system and noise in the cab.
EP0485724 A1 describes a hydraulic system for tipping the cab, which is coupledin through a combination of translation and rotation. A pick-up element isdesigned with a recess that fits with an element on the cab. The movement between the elements can, however, give rise to wear of the system.
It is an object of the invention to provide a stable device which canachieve a controlled rotation and lines movement of its piston rod, and inespecially as it is possible to tip a vehicle cab.
Summary of the InventionAccording to a first aspect, the object described above is achieved by a stable device whichincludes a motor, a threaded rod, a nut assembly, a piston assembly and a housing.
The motor is arranged to drive the actuated rod via a gearbox. The actuator comprises a first part on the nut unit and a second part on the housing which realizes a first controlling function for the actuator, the first part being arranged to fit with the second part, so that the nut unit follows apredefined first path determined by the first part and the second part as the first and the second part are aligned with each other and the motor drives the stepped rod.
The first aspect gives rise to a stable device that can perform a controlledaxial rotation of the nut unit, and in turn the piston unit. The stable canthus performing both a linear motion and a rotation about a center line of the stepped rod. This can be useful in many applications, and is performed by actuating the engine only. The first control function constitutes a form of rotation limitation between the piston unit and the housing. The housing can be designedas a cylinder around the nut unit and piston unit. The predefined first coursedescribes the movement of the nut unit and / or the piston unit that is requested.3The stable device may comprise a third part on the nut unit and a fourth part on the piston unit which realizes a loading function for the stable device. The third part is arranged to fit with the fourth part so that the nut unit follows a predefined load path determined by the third part and the fourth part to a loadmake the piston unit to the nut unit, as the nut unit follows the predefined onef6rsta banan. By having a loading function, the stabilizer can be connected to ice and connected, and is locked when it is connected so that the stable device can both be used to lift and pull without falling ice. The loading function is actuated by only actuating the motor. The loaded layer can also be called form loading.
The stable device may also comprise a fifth part on the piston unit and a sixth part on the housing which realizes a second controlling function for the stable device. The fifth part is arranged to fit with the sixth part so that the piston unit follows a predefined second path determined by the fifth and the sixth part when itthe fifth part and the sixth part are aligned with each other and the motor drives the actuated rod. On such salt, a control of the piston unit is achieved so that the piston unit has a desired behavior, for example a rotation, or a loading in a certain path. The second control function can also be used to control the piston unit so that a load layer of the piston unit to the nut unit is maintained. Thethe second control function prevents the piston unit from rotating with the gearthe rod, and forms a form of rotation restriction between the piston unit and the housing. The housing around the nut unit and the piston unit may be in the form of a cylinder.
According to a second aspect, the object is achieved at least in part by acab tilting device for vehicles, which comprises a stable device according to any oneexecution from which is described herein. The stable device is arranged to be attached to the vehicle chassis in one spirit and to the vehicle's cab in its other spirit. The cab tilting device further comprises a control unit and / or input unit which is arranged to actuate the tilting of the cab. The second aspect providesOpportunity to shovel both interconnection of stables and cab, as well as tipping ofthe vehicle's cab with one and the same component.4The use of a stable device, for example a linear stable device, with internal release controlled by controlled axial rotation provides the opportunity to replace existing hydraulic devices with an electrical device that has lower internal friction and thus potentially generates less noise in the cab.
According to a third aspect, the object is achieved at least in part by a vehicle comprising a stable device according to the flake design described herein, and / or a cab tilting device.
According to a fourth aspect, the object is achieved at least in part by a method forcontrol a stable unit comprising a motor, a geared rod, a nut unit, a piston unit and a housing. The method includes that- place the nut unit on the threaded rod in the housing so that a first part of the nut unit and a suitable second part of the housing run into each other;- drive the threaded rod so that the nut unit follows a predefined firstpath bounded by the first part and the second part.
