Definitions

• the Erfmdunq relates to a lifting and swiveling device f a motor vehicle with a bottom-side lifting device which carries a vertically movable lifting arm which can be fixed laterally at the bottom of the motor vehicle and which can be actuated by a drive device which can be locked in any desired lifting positions.
• the lifting device has a lifting height which corresponds to at least a maximum vehicle width, and has a pair of swivel runners which are to be arranged opposite the lifting device on the motor vehicle and which each have an e 1/4 circular section with tanqential spouts exist on the inside of the circle fastening and / or receiving devices are held, which are to be connected to traq capable parts of the motor vehicle, and their outlets extend na above the center of gravity in the assembled state to the side of the motor vehicle.
• the device is advantageously designed so that it can be adapted to different vehicle widths and different wheelbases by means of telescopic locks which can be locked.
• the device is advantageously attached to the wheel receptacles, since the wheel suspensions are designed for the load that occurs when the vehicle is pivoted.
• the fastenings on the wheel holders are advantageously designed as suitable screwable disks that are detachably connected to the swivel skids.
• the lifting device which is preferably designed as a lifting spindle drive, is advantageously supported at the bottom on a pair of rollers, which is connected by means of a pull connector at the end of the swivel skids, so that when lifting and swiveling the vehicle, the lifting device is always slightly inclined and its lower part is pivoted the vehicle is used, so that the working space to the underside of the vehicle is relatively free, the bending forces on the lifting device remain low, and only slight lateral thrust forces are exerted on the vehicle.
• the device can be attached to each side of the vehicle, so that a respective underside area of interest can be reached at a handy height
• the lifting device can be a hydraulic jack or a pneumatic jack if suitable supply units are available for it.
• a simple lifting spindle is preferably used, which is to be actuated at the top end via a bevel gear transmission with a latch locking device and a crank or preferably with a motor via a self-locking transmission.
• the connection between the gear and the motor is detachable and the motor connection is designed to fit a commercially available drilling machine, so that it can be clamped there.
• a support is pivotably arranged between the swivel runners, d is vertical in the fully swiveled position and, in addition to the locked lifting device, prevents the vehicle from swiveling back.
• the front and rear swivel skids are connected at the ends by a plug-in connecting rod so that the side region of the motor vehicle to be swiveled down is protected when swiveling and, conversely, people and objects are kept away from the side region when swiveling.
• the connecting rod is arranged at an altitude such that the center of gravity of the vehicle lies significantly below it, so that in the tilted state the vehicle does not inadvertently swivel over it and tilts onto the roof.
• the swivel runners are each formed from a pair of curved tubes, which are welded to one another by cross struts and provide a directed hold for the fastening plates arranged in between to the wheel holders. As a result, the entire device is stable and still light, and when disassembled it takes up little space.

• Fig. 1 shows a front view of the device after mounting on the motor vehicle (1).
• the lifting device (2) is screwed to a wheel receptacle (10) by means of a lifting arm (21) by means of a bracket (27) fastened thereon with a pivoting gel (26).
• the lifting arm (21) is fastened with nuts on the spindle (20) inside the lifting device (2) and is displaceably mounted in the surrounding housing.
• the lifting spindle (20) is connected at the top to an angular gear (24) to which a lifting motor (25) is detachably flanged.
• the lifting device (2) has an axle (23) at the bottom on two wheels (30) in the direction of the lifting arm (21
• the axle (23) has two parallel tension struts (31, 31A) which are articulated to the swivel device (4, 4A), approximately centrally below the motor vehicle (1), for which the tension struts (30, 31 A) and the swivel skids (4, 4A) of the swivel device can be adjusted in length to different vehicle widths in a telescopic manner.
• the swivel device consists of a pair of swivel skids (4, 5), the second of which is only partially visible in FIG. 1, but is fully visible in FIG. 4.
• the pair of swivel runners (5) is connected to one another by a connecting rod (6, 6A) which can be adjusted in length, in that pipe sockets (61, 62) are welded at right angles to the end of the connecting rod (6, 6A) and are connected to the tubular ends of the swivel runners (4 , 5) are inserted and secured there.
• the connecting rod (6, 6A) which consists of tubes that fit into one another, is adjusted to the appropriate length by a locking device (60).
• the swivel runners (4, 5) are curved approximately 1/4 in a circular arc, and they end on both sides in tangential extensions.
• Each runner (4) is connected in pairs with a parallel runner (4A) at a distance of about 20 cm by cross struts (40), and between the two runner (4, 4A) the fastening device (41) is welded to the inside of the circle aligned.
• the fastening device (41) consists of a fastening plate (42), which is held on welding bars with support brackets (43) by insertable bolts (44). The bolts (44) are secured against slipping out with resilient locking pins (45).
• the fastening plate (42) is designed to match the wheel holder (11) and is to be screwed there in the same way as the vehicle wheel removed in each case.
• the fastening device (41) is arranged at one end of the circular arc, and from there a tangential end of the runner (4) extends slightly inclined from the vehicle to about 3/4 of the vehicle height, where the connecting rod (6, 6A) in the runner (4) is inserted at the end.
• the radius of the circular arc corresponds to approximately 1/4 to 1/3 of the vehicle width.
• the tangential ends of the runners (4, 4A) under the vehicle are through pull-out tubes (4B) can be extended to the center of the vehicle and locked with bolts, so that the end of the tubes (4B) with the joint (32) of the pull rod (31, 31A) is to be arranged approximately centrally under the vehicle (1).
• Fig. 2 shows the device in the pivot position, the end position has not yet been fully reached.
• the lifting arm (21) has been brought approximately into its upper end position by the lifting motor (25) and the vehicle (1) has thereby been lifted on one side.
• the bearing (23) at the end of the tube (4B) of the swivel runner (4) has been raised and as a result the pull rod (31, 31A) mounted thereon has pulled the wheels (30) towards the vehicle (1), causing the lifting device (2 ) is only slightly inclined against the vertical and is therefore exposed to a low bending force, and requires little space on the side and does not push the vehicle (1) to the side.
