Description

  • The invention relates to a lifting device for the maintenance or repair of vehicles, in particular commercial vehicles.
  • Maintenance work on commercial vehicles are physically very strenuous for the persons performing the maintenance, since the components to be handled during maintenance usually have a large design and a high weight. For example, wheels or hubs of a truck often weigh more than 50 kg. Therefore, it is often required that several people carry out maintenance work on a vehicle together to reduce the burden on the individual worker.
  • Proceeding from this, it is an object of the invention to provide a lifting device, facilitated by means of the maintenance work to be carried out and in particular can be performed by a single person.
  • The object is solved by the features of independent claim 1. Preferred embodiments are subject of the dependent claims.
  • According to a first aspect, the invention relates to a lifting device for components of a vehicle, in particular a commercial vehicle. The lifting device comprises a chassis comprising a plurality of rollers, a pillar projecting upwardly from the chassis, and a boom arm, which is arranged pivotably on the pillar and protrudes therefrom. At the opposite end of the column free end of the boom is a tool holder for interchangeable receiving a tool provided in which a tool used for the support of the component of the utility vehicle can be fixed. "Fixable" in this context means in particular that the tool is held by the tool holder in a defined position. This tool holder is pivotable about a horizontal pivot axis relative to the cantilever arm.
  • The lifting device has the distinct advantage that various tools can be fixed by the tool holder on the boom, by means of which different maintenance and repair work can be supported, the tool can be positioned in different pivot positions, by actively made by the user adjusting the pivot position of the tool holder.
  • According to one embodiment, a drive, in particular a manual drive for pivoting the tool holder is provided. The drive can be done for example via a crank or a handwheel. In particular, the drive may comprise a shaft and a displacement mechanism, by means of which a rotational movement of the shaft is converted into a translational movement. Alternatively, a shaft and a worm gear is provided, via which a rotational movement of the shaft is converted into a pivoting of the tool holder.
  • Preferably, the tool holder protrudes from the front of the cantilever arm and is pivotable about the free end of the cantilever arm around.
  • According to one embodiment, the tool holder is pivotable by a spindle drive or a worm drive. The spindle drive can implement an example manually introduced rotary motion in a translational movement, wherein the translational movement is implemented via the tool holder itself or provided in the tool holder lever mechanism in a pivoting movement of the tool holder. Via a worm drive or a worm gear, the rotational movement of the shaft can be converted directly into a pivoting movement of the tool holder.
  • Alternatively, it is possible to pivot the tool holder by a gear, such as driven by a lever or a ratchet-shaped drive mechanism (e.g., plug-in ratchet or punch-in ratchet).
  • According to one embodiment, the tool holder is an angular range in the range between 45 ° and 360 °, in particular of at least 70 °, 80 ° or 90 °, preferably by an angular range of at least 120 °, more preferably by an angular range of at least 140 ° about the free end of the boom pivot. Especially by worm gear or gear transmission can be a large Verschwenkwinkelbereich, in particular reach up to 360 °. As a result, a high degree of flexibility is achieved when using the lifting device.
  • According to one embodiment, the tool holder is designed such that a tool section can be inserted or inserted into or plugged onto the tool holder. In particular, the tool holder can be received in a form-fitting manner in the tool section or the tool section can be positively attached to the tool holder. As a result, a rotationally secure mounting of the tool in the receptacle can be achieved.
  • Alternatively, the tool portion may be rotatably received in the tool holder to allow pivoting of the tool about a longitudinal axis of the tool holder. For this purpose, the tool holder may be formed, for example, a round tube, so that the tool portion is freely rotatable in the tool holder. To prevent the falling out of the tool, a displacement protection, for example formed by a bolt, can be provided.
  • Preferably, the tool holder is designed such that the tool can be fixed in a plurality of rotational positions on the tool holder. Preferably, the tool holder is sleeve-shaped and has a square, hexagonal, octagonal or generally polygonal cross-section, so that a fixing portion of the tool in different rotational positions in the tool holder can be inserted. Alternatively, the tool holder may have a toothing which is formed, for example, on the inner circumference side in a sleeve-like tool holder or on the outer peripheral side on this tool holder.
  • According to one embodiment, the tool has a receiving portion for a vehicle rim, wherein the receiving portion comprises at least one roller. In a preferred embodiment, at least two, more preferably at least three rollers are provided on the receiving portion, whose axes of rotation are arranged relative to each other arc segment-shaped. The at least one roller forms with its running surface a contact surface for a rim portion. Due to the rotatability of the roller held on the tool rim can be rotated, for example, to change the orientation of the rim relative to the wheel hub, in particular to change the rotational position of the rim for mounting the same on provided on the wheel hub bolt.
  • According to one embodiment, the running surfaces of the rollers form outer peripheral side bearing areas for a curvature provided in the region of the rim flange. In particular, the arc segment-shaped arrangement of the axes of rotation of the rollers is adapted to each other to the radius or diameter of the curvature of the rim flange. In addition, the rollers are designed such that they engage positively or substantially positively with their treads in the curvature. Thus, the wheel or the rim is securely held hanging on the rollers.
  • According to one embodiment, the running surfaces of the rollers are convexly curved in the direction of their axis of rotation. The radius of curvature is particularly adapted to the radius of the rim horn provided curvature. This allows the running surfaces of the rollers engage positively in the curvature of the rim flange.
  • According to one exemplary embodiment, at least one, preferably at least two, contact rollers are provided on the chassis, the running surface of which forms a contact region for a vehicle tire held on the extension arm. In the hanging support of the wheel on the lifting device, the edge of the vehicle tire bears against the running surface of the at least one contact roller, so that the wheel can easily be rotated in this suspended position, for example to change the orientation of the rim relative to the wheel hub. This keeps the wheel in a vertical or substantially vertical orientation.
  • According to one embodiment, the tool has a suspension eye. This suspension eye is provided, for example, on the side opposite the rollers (the rollers used for the hanging support of the rim). This allows the tool to be used alternatively for lifting components by hanging in this suspension eye.
  • Preferably, in the region between the attachment eye and the receiving portion with the at least one roller, which is designed to rest against a curvature in the region of the rim flange, an obliquely extending stop is provided. This stop forms a contact section for the tire, so that when lifting the tool via the lifting device, the at least one roller engages in the curvature in the region of the rim flange. This ensures that when lifting a tire in the degraded state, this only has to be based on the tool and when lifting the roller is automatically inserted into the curvature in the region of the rim flange.
  • According to one embodiment, the tool has at least two fork-like projecting holding sections for fixing a wheel hub or brake drum. These holding portions are formed or arranged such that a wheel hub flanged to the tool and thereby can be handled by the lifting device.
  • According to one embodiment, openings or bores are provided on the holding sections through which bolts provided on the wheel hub or screwable there can be passed. Thus, the tool can be permanently but detachably connected to the wheel hub in order to handle these by the lifting device can.
  • The invention further relates to tools to be mounted on the tool holder, in particular a tool for handling wheels or rims of a vehicle, a tool for handling wheel hubs and a tool for handling brake calipers.
  • For the purposes of the present invention, "commercial vehicle" is understood in particular to be trucks, buses, but also agricultural vehicles and trailers.
  • The expressions "approximately", "substantially" or "approximately" in the context of the invention mean deviations from the respective exact value by +/- 10%, preferably by +/- 5% and / or deviations in the form of changes insignificant for the function ,
  • Further developments, advantages and applications of the invention will become apparent from the following description of exemplary embodiments and from the figures. In this case, all described and / or illustrated features alone or in any combination are fundamentally the subject of the invention, regardless of their summary in the claims or their dependency. Also, the content of the claims is made an integral part of the description.

  • The 1 and 2 show an embodiment of a lifting device 1 in different representations. The lifting device 1 is in particular a multi-function lifting device to which, as explained in more detail below, different tools can be attached to make these tools with low power and personnel costs maintenance and repair work on commercial vehicles.
  • The lifting device 1 has a chassis at the bottom 2 with several roles 3 on. Thus, the lifting device 1 be moved on a footprint, for example, the floor of a workshop. The roles 3 can be at least partially designed as castors. The chassis 2 can in particular two chassis arms 2.1 . 2.2 have along the longitudinal direction of the chassis 2 run. For stiffening the chassis 2 can have one or more cross braces 2.3 be provided.
  • From the chassis 2 stands in the back area a pillar 4 upwards. The pillar 4 may in particular perpendicular or substantially perpendicular to the chassis 2 protrude. The pillar 4 can, as in the 1 and 2 shown from a pair of columnar arms 4.1 . 4.2 be formed, the spaced preferably parallel to each other. The pillar arms 4.1 . 4.2 can thereby by at least one connecting strut 4.3 be connected to each other. In the embodiment shown are in the upper side region of the column 4 handles 4.4 provided by means of which the lifting device 1 procedure or can be handled in any other way. Alternatively, the column 4 have only a single column arm.
  • From the pillar 4 stands forward (ie in the same direction in which the chassis 2 opposite the column 4 projecting) a boom 5 from. This boom arm 5 is pivotal on the column 4 held, and pivotally about a horizontal first axis of rotation DA1 , In the illustrated embodiment, the cantilever arm 5 with its free end between the columnar arms 4.1 . 4.2 the column 4 arranged and by a the first axis of rotation DA1 forming swivel joint between the columnar arms 4.1 . 4.2 is formed, pivotally mounted on the column 4 held. The boom arm 5 includes in the illustrated embodiment, two parallel or substantially parallel to each other Auslegerarmabschnitte 5.1 . 5.2 arranged spaced apart from each other and by at least one transverse strut 5.3 are connected. Alternatively, the cantilever arm 5 also have only a single Auslegerarmabschnitt.
  • For pivoting the extension arm 5 is a lifting cylinder 9 provided, which is in particular a hydraulically operated lifting cylinder. The lifting cylinder 9 extends in the embodiment shown between the plane of the chassis 2 and the boom arm 5 , and is, for example, with a first Hubzylinderende in the rear of the chassis 2 (For example, at a point where the column 4 protrudes upward) and a front Hubzylinderende in a front region of the boom 5 hinged. The piston rod of the lifting cylinder 9 For example, can be extended foot or hand operated to the boom 5 to pivot. In the embodiment shown is a foot pedal 9.1 provided for actuating a hydraulic pump. Lowering the boom 5 can also be done foot or hand operated. In the embodiment shown is a rotary 9.2 provided by means of a retraction of the piston rod of the lifting cylinder 9 can be effected. Alternatively, it is conceivable that the retraction of the piston rod by a pivotable handle (similar to a brake lever of a bicycle) is effected, for example, in the region of the handle 4.4 is provided. This can improve the positionability.
  • At the pillar 4 removed free end of the boom 5 is a tool holder 6 intended. This tool holder 6 is designed to interchangeably receive a tool. The tool holder 6 may in particular be designed such that the tool can be replaced quickly, especially without tools. In particular, the tool holder 6 be sleeve-shaped, so that a tool shank of the tool in the tool holder 6 can be inserted or suspended and held in a form-fitting manner. Alternatively, the tool shank on the tool holder 6 be pluggable. The tool holder 6 may in particular have a round or polygonal cross-sectional shape, for example a square or hexagonal cross-sectional shape. The tool holder 6 can also be adapted to the tool by securing means against unwanted detachment from the tool holder 6 to secure. The securing means can be formed in particular by a plug-in or screw-in bolt. Furthermore, the tool holder 6 be formed by a shaft with a toothing.
  • The tool holder 6 is pivotable about a horizontal second axis of rotation DA2 at the free end of the extension arm 5 arranged. The second axis of rotation DA2 runs preferably parallel or substantially parallel to the first axis of rotation DA1 , In particular, a free end of the tool holder 6 around the free end of the boom 5 to be moved around in a circular arc shape, as in 1 indicated by the double arrow. This can be a in the tool holder 6 held tool relative to the boom 5 be pivoted, for example, to position the tool in a specific required for installation or removal pivot position. Preferably, the tool holder 6 infinitely swiveling. The pivotability can be from 45 ° to 360 °, in particular an angle range of at least 70 °, 80 ° or 90 °, preferably of at least 120 °, particularly preferably of at least 140 °.
  • The pivoting of the tool holder 6 is preferably done manually, for example by a remote from the tool holder 6 lying actuator 7th The actuator 7 especially in the area of the column 4 lie, in particular in an area immediately in front of or behind the column 4 ("Before" or "behind" with respect to the tool holder 6 ). The actuator may be, for example, a crank or a handwheel. The force or torque transmission from the actuating element to the tool holder to be pivoted takes place, for example, by means of a shaft. The shaft may have a thread, so that upon rotation of the shaft, the rotational movement is converted into a translational movement or a sliding movement. The translational movement / displacement movement can then via a lever arm 6.1 , as in 1 shown in a pivoting movement of the tool holder 6 be implemented.
  • Alternatively, the actuating element 7 in the region of the tool holder 6 or between the tool holder 6 and the pillar 4 lie.
  • Furthermore, alternatively, it is possible that the rotational movement of the shaft via a worm gear in a pivoting movement of the tool holder 6 is implemented.
  • Below are different tools and their use on the lifting device 1 described. 3 to 5 show a first tool 10 in different views. The tool 10 is a multi-function tool and can, as described below, be used for different maintenance or service work on the vehicle.
  • The tool 10 has a shaft-like fixing section 10a on, with respect to the cross-sectional shape of the cross-section of the tool holder 6 is adjusted. In particular, the fixing section 10a in the sleeve-like tool holder 6 insertable. Alternatively, the fixing section 10a on the tool holder 6 attachable. The fixing section 10a can one to the tool holder 6 adapted, polygonal cross-section, for example, have a square, hexagonal or octagonal cross-section. Alternatively, the fixing section 10a be designed as a round tube or have a round cross-section. The tool 10 also has a receiving section 10.1 on, by means of which a component of the vehicle is manageable. This component may in particular be a rim or a wheel of a vehicle. To handle the component are on the receiving section 10.1 at least one role 10.2 , preferably several roles 10.2 provided, which serve for the hanging support of a vehicle wheel or a vehicle rim. Rims of a commercial vehicle typically have a rim flange with a curvature or groove pointing in the direction of the center of the rim. The roles 10.2 are formed for hanging the rim by inserting portions of the roller tread in this camber or groove. The roles 10.2 are rotatable about axes of rotation DA3 stored, for example, obliquely with respect to the fixing 10a run.
  • In the embodiment shown are on the receiving portion 10.1 four roles 10.2 provided, which are offset from one another. It is understood that the tool 10 of which deviating both more or less than four roles 10.2 can have. The axes of rotation DA3 the roles 10.2 are, as in 3 indicated by the dotted line on the tool 10 arranged arcuately, ie the axes of rotation DA3 come to lie on a curved, arc segment-shaped line. This can when using the same size roles 10.2 be achieved that tread portions of all roles 10.2 abut against the curvature provided on the rim flange. Alternatively, it is conceivable that the rollers 10.2 have different diameters, in particular such that the inner rollers have a larger diameter than the outer rollers.
  • The rollers have a transversely curved to the circumferential direction tread, ie the tread is not only curved in the circumferential direction, but also has a convex curvature in the direction of their respective axis of rotation DA3 on.
  • At the receiving section 10.1 Opposite the rollers is a suspension eye 10.3 intended. By means of this suspension eye 10.3 a vehicle part can be raised or lowered.
  • Between the attachment eye 10.3 and the receiving section 10.1 can be a stop 10.5 be provided. This stop 10.5 forms a contact portion for the tire, so that when lifting the tool on the lifting device, the at least one roller 10.2 engages in the vault in the area of the rim flange. This ensures that when lifting a tire in the degraded state this only to the tool 10 ajar and lifting the roll (s) 10.2 automatically inserted into the camber in the area of the rim flange.
  • 6 and 7 show the use of the tool 10 when handling a wheel of a commercial vehicle. To lift or remove the wheel from the hub is the tool 10 in the tool holder 6 the lifting device 1 used in such a way that the rollers 10.2 below the suspension eye 10.3 are arranged. The tool 10 is for example by a screw-in safety pin 10.4 opposite the tool holder 6 secured. Other securing means are conceivable in principle.
  • Subsequently, the lifting device 1 positioned so opposite the wheel that the rollers 10.2 below the rim flange 31 the rim 30 provided vaulting 32 to come to rest. Subsequently, the boom arm 5 moved upward so that portions of the running surfaces of the rollers 10.2 opposite the vault 32 of the rim flange come to the plant. As already indicated above, the rollers may have a convex curvature transversely, in particular perpendicular to the circumferential direction, so that the roller treads in sections form-fitting manner in the curvature 32 of the rim flange 31 intervention.
  • After this intervention, the wheel of the commercial vehicle with little physical effort, in particular without lifting the wheel by the repair staff themselves from the Wheel hub are deducted by the wheel by moving the lifting device 1 is transported hanging.
  • Subsequently, the wheel can be parked, for example, on a wall by the boom 5 is lowered. The free ends of the chassis arms 2.1 . 2.2 may be formed such that when lowering the tire, this in the column 4 tilted away direction and thus can be ajar against a wall, for example. This can for example by an oblique divergence of the free ends of the chassis arms 2.1 . 2.2 or a suitable bevel of the contact areas of the chassis arms 2.1 . 2.2 , on which the tire rests circumferentially, can be achieved, so that the wheel when setting a tilting moment in the column 4 opposite direction learns.
  • As in 7 shown is the on the rim 30 mounted tires of the wheel while the running surfaces of investment rolls 8th at. These investment roles 8th are on the chassis 2 provided, in such a way that the axes of rotation of the investment rollers 8th up from the chassis 2 protrude.
  • Through the roles 10.2 of the tool 10 and the investment roles 8th that is achieved on the tool 10 hanging wheel, like in the 6 and 7 indicated by the double arrow, rolling the rollers 10.2 opposite the rim 30 and under unrolling of the installation rollers 8th can be rotated against the tire. Thereby, a facilitated alignment of the wheel when mounting to the wheel hub can be achieved, in such a way that the bolts provided on the wheel hub can be pushed through the openings provided in the rim. In addition, the contact rollers prevent tilting of the wheel, ie the contact rollers keep the wheel perpendicular or substantially vertical.
  • 8th and 9 show another tool 20 , which is designed for handling a wheel hub of a vehicle. The tool in turn has a fixing section 20a on, for example, is tubular and has a polygonal or round, in the illustrated embodiment square cross-section. The cross section is in turn at the cross section of the tubular tool holder 6 customized. This allows the tool 20 as well as the tool described above 10 in different angular positions or rotational positions in the tool holder 6 be inserted.
  • The tool 20 is fork-shaped and has two holding sections 20.1 . 20.2 on the from a transversely, in particular perpendicular to the fixing 20a extending base section 20.3 upwards, ie the fixing section 20a stand out on the opposite side. The holding sections 20.1 . 20.2 are formed in the embodiment shown canted or bent. Alternatively, these can also be straight from the base section 20.3 protrude.
  • Through the holding sections 20.1 . 20.2 and the base section 20.3 becomes a partially circumferentially limited recording area 20.5 formed, which is designed to partially surround a wheel hub. The holding sections 20.1 . 20.2 and preferably also the base section 20.3 have holes 20.4 on, through which provided on the scar or screwed there bolt can be passed. The width b the holding sections 20.1 . 20.2 is selected in relation to the length of the bolts such that the bolts at least partially on the side opposite the wheel hub relative to the holding portions 20.1 . 20.2 protrude, leaving the tool 20 can be determined by screwing the nuts on the bolts on the wheel hub.
  • 10 and 11 show the use of the tool 20 on the lifting device for removing or attaching a wheel hub 40 or for storing the wheel hub 40 , The wheel hub has a mounting area for a wheel on which a plurality of bolts 41 are provided. At the bolt 41 opposite, rear side of the wheel hub 40 a brake disc is provided, as is common in commercial vehicles. To replace the brake disc, therefore, the wheel hub 40 be dismantled from the vehicle.
  • This is done in the tool holder 6 recorded tool 20 by pivoting the tool holder 6 placed in an upright position so that the holding sections 20.1 . 20.2 perpendicular or substantially perpendicular to the chassis 2 stand or the holding sections 20.1 . 20.2 a contact surface for the wheel hub 40 form parallel to a Radanlagefläche 42 the wheel hub 40 runs. Subsequently, the lifting device 1 so moved up to the wheel hub still located on the vehicle, that at least one, preferably a plurality of bolts 41 through the holding sections 20.1 . 20.2 protrude through ( 10 ). Subsequently, the tool can 20 with the wheel hub 40 screwed by unscrewing nuts. After loosening the connection between wheel hub 40 and axle or stub axle can be the wheel hub 40 by moving the lifting device 1 be removed from the axle or stub axle.
  • As in 11 shown, the wheel hub 40 then by pivoting the tool holder 6 be brought into a horizontal orientation so that the wheel hub 40 For example, on a workbench (after lifting the boom 5 ) or can be stored on another storage area.
  • 12 shows a tool 50 for the handling of calipers of commercial vehicles to these on the lifting device 1 to be able to lift. The tool 50 has a rod-shaped clamping device 51 and two clamping elements 52 . 52 ' on. The clamping device 51 For example, a clamping bolt, in particular a screw having at least sections of a thread. The threads are in particular in the end regions of the clamping device 51 intended. The clamping elements 52 . 52 ' each have a forked receiving portion 53 on, which is designed to receive a web-like wall portion of a caliper. The recording section 53 For example, has a U-shaped or substantially U-shaped cross-section and is characterized by clamping element sections 53.1 . 53.2 laterally limited. The clamping elements 52 . 52 ' are so on the clamping device 51 arranged that the clamping element sections 53.1 . 53.2 the two clamping elements 52 . 52 ' each have obliquely outwards, ie, on a side facing away from the center of clamping means.

The wall opening 61 becomes laterally by webs 62 limited. The clamping elements 52 . 52 ' are trained to use this jetty 62 to embrace sections. The clamping elements 52 . 52 ' are located on one of the wheel axle spaced outside of the caliper 60 on the footbridges 62 deferred and braced against each other (for example by turning the nuts) that the clamping elements 52 . 52 ' to the opposite webs 62 be pressed. This allows the tool 50 on the caliper 60 be tightened so that this by means of the tool 50 and the lifting device 1 can be lifted off the brake caliper receptacle.
  • 14 and 15 show different ways of handling one on the tool 50 held caliper. For example, with stationary built calipers, the tool 10 to the tool holder 6 be attached and the tool 50 can have one on a tensioning element 52 . 52 ' attacking connecting means, such as a shackle o.ä. with the attachment eye 10.3 of the tool 10 get connected.
  • In a top, lying installation situation of the caliper, for example, the tool 20 to the tool holder 6 be attached and the tool 50 may or the like via a pair of connecting means, such as a pair of shackles. into the holes 20.4 of the tool 20 be hung.
  • Through the tools described above 10 . 20 and 50 together with the lifting device 1 It is possible to carry out maintenance or repair work such as changing the tires, removing the caliper of the caliper mount, removing the wheel hub from the axle or the stub axle etc. with little effort and personnel.
  • The tools form next to the lifting device 1 separate articles of the invention.
  • The invention has been described above by means of exemplary embodiments. It is understood that numerous changes and modifications are possible, without thereby departing from the invention underlying the idea of the invention.
