Definitions

  • the invention relates to a vehicle, in particular a shovel loader with a loader arm articulated on the front and a motor suspended on the rear, and with a rigid frame comprising longitudinal and cross members, the side longitudinal members of which extend portal-like over the rear wheels and in the region of the middle section of the vehicle at the level of the entrance adjoining vehicle floor.
  • a shovel loader of this type is known from German Offenlegungsschrift 29 05 528.
  • the side longitudinal members In order for this frame to be sufficiently stable even for vehicles with a high steering angle, where high torsional stiffness is particularly important, the side longitudinal members must be appropriately dimensioned, which has a negative effect in terms of increasing the vehicle weight.
  • a mobile working device is known with a motor arranged on the side of the driver's cab, which has side longitudinal members with front sections that extend partially over the front wheels and on which the front part of the vehicle is built.
  • the invention has for its object to make a vehicle of the generic type particularly stiff while saving weight and this sufficient stability even for a particularly high steering angle of about To give 60 °.
  • the side longitudinal members have a front section which extends partially over the front wheels and on which the front part of the vehicle is built, that the frame has a central longitudinal beam running approximately at the level of the vehicle floor, extending between the wheel axles and rearward to the rear of the vehicle, which is connected directly or via supports to a plurality of cross members and on the underside of which the axle flanges are provided for fastening the rear axle, and that the frame is additionally stiffened, including parts of the vehicle body in the area of the rear, the front section and the entry.
  • the side members can be dimensioned more easily compared to the prior art; nevertheless, an increased rigidity of the structural unit consisting of the vehicle frame and the vehicle body can be achieved by the proposed integration of parts of the vehicle body in the area of the rear, the front part and the entry into the frame.
  • the central longitudinal beam which is the essential link both in the longitudinal direction and in the transverse direction of the vehicle.
  • the cross members directly or indirectly connected to the central longitudinal member;
  • the forces to be absorbed by the vehicle are introduced into the load-bearing parts of the vehicle body via it.
  • the central longitudinal member is the central supporting element which, on the one hand, supports the rear box of the vehicle, which is loaded with the counterweights, against its central section and on which the weight of the drive unit and the supporting forces from the rear axle of the vehicle act in the vertical direction.
  • the two side longitudinal members are connected to one another at the front by a front box which is composed of a left and a right box part, which between them include a channel piece which is open to the front and into which the vehicle-side end of the loading arm connected there intervenes.
  • the front box and the associated front section of the side longitudinal members not only have to absorb the considerable forces which are introduced via the loading arm; There the supporting forces of the front axle also attack, whereby according to the invention it is provided that the supporting walls of the channel piece are extended towards the front wheel axle by downwardly projecting axle plates, at the ends of which axle flanges are attached for fastening the front axle.
  • several particularly expedient design measures are provided according to the invention.
  • Such a measure consists in the formation of the two box parts, which are to the rear, that is open to the driver's cabin, otherwise formed by the front panel, side panels and foot panel of the front vehicle body.
  • a front spar is provided in the interior of the box parts as a further cross member, which is connected on the outside at the front end of the associated side longitudinal member and on the inside to the adjacent side wall of the channel piece.
  • the middle longitudinal beam is formed in its length section between the rear box and the central section of the vehicle, where it is connected to a central beam as a cross beam, as a U-profile beam.
  • the central longitudinal beam can also be designed as a profile beam with a closed box profile.
  • the central longitudinal member is extended forward through a tunnel in the form of a sheet metal box which is open at the bottom or closed and which is connected on the one hand to the central strut and on the other hand to the duct section of the front box.
  • this tunnel represents an essential part, the front section with the central section of the vehicle connecting support element next to the side members.
  • a foot plate is attached, which is attached to the outside of the respective side member and extends forward where it forms the bottom of the associated box part of the front box.
  • cross members are provided at a vertical distance above the central longitudinal member, namely a rear spar parallel to the upper edge of the rear and a front spar parallel to the upper edge of the front box.
  • a cross member is provided as a further cross member, which connects the side longitudinal members to one another via the rear wheels and the ends thereof to the central longitudinal member via inclined supports are connected.
  • the diagonal supports preferentially engage on the central longitudinal spar between the axle flanges for fastening the rear axle.
  • the front section (1) can be divided into the front section (1), the central section (2) of the vehicle and the rear of the vehicle (3).
  • the two side longitudinal members (4) extend from the front section (1) to the rear of the vehicle (3), bridging the front wheels approximately in half and completely bridging the rear wheels.
  • the front wheels (5) and the rear wheels (6) are indicated by dashed lines.
  • a rear box (7) which extends in the transverse direction of the vehicle, so that it is located behind the rear wheels; on the front end of the side members (4) a front box (8) is attached, which consists of a right and a left box part (9) and a channel piece (10) which is arranged between the two box parts (9) and is open to the front and in which the vehicle-side end of the loading rocker (not shown) is articulated.
  • the two box parts (9) are each open to the driver's cab (not shown) and each formed by a front plate (11), side plate (12) and foot plate (13).
  • the two box parts (9) are each stiffened by two cross members, namely a front spar (14) and a front spar (15). Both spars are connected on the inside to the adjacent side walls (16) of the channel piece (10); towards the outside, the front spars (14) are attached to the respective inner side of the lateral longitudinal spars (4) and the front spars (15) on the inner side of the side plates (12) of the box parts (9).
  • Front and front spars (14, 15) are each designed as hollow sheet metal profiles. They are produced either by welding prismatic partial profiles or by shaping the front spar (15) from the front plate (11) and by shaping the front spar (14) from the front plate (11) or from the foot plate (13).
  • the longitudinal bars (4) are pulled down to form an entry, an entry threshold (17) via a front inclined part (18) with a front horizontal part (19) and via a rear inclined part (20 ) is connected to a rear horizontal part (21) of the side members (4).
