Definitions

  • the invention relates to a refuse collection vehicle with a rotating drum serving as a collecting container, the rear open end wall of which can be closed by a non-rotatable cover equipped with a screw-shaped baffle acting as a clearing and pressing screw for the waste, and the front end wall of which is mounted on a central pivot in a bearing block and their rear-side mounting via a large ball bearing with attachment of its outer ring to a lower support, which is axially supported on a pin which sits on a subframe attached to the vehicle frame below the drum axis line, and which lies loosely on the subframe on both sides of the pin transversely to the rotary drum axis line , wherein at the rear end of the rotary drum, a ring gear is attached to its rotary drive by a pinion on its outer jacket.
  • FIG. 1 of the following drawings Such a refuse collection vehicle is known from DE-PS 1 144 185 and its essential elements are shown in FIG. 1 of the following drawings. It carries a rotating drum 1, the rear end of which is closed by an end cover 2 which is held on the chassis 3 and can be folded up relative to the rotating drum.
  • the cover 2 carries a truncated hollow cone 5 protruding into the inside of the rotating drum, on the outside of which a screw-shaped baffle 6 is fastened, which extends from the upper vertex S on the cover plate to about 180 ° to a point E on the inner truncated cone plane and thus an incline has, which extends over the entire depth of the truncated cone 5 in the said angular range.
  • the guide plate 6 is extended in the radial direction by a further 90 ° in the form of a segment of a circle. It serves to prevent the bulk material, which is conveyed axially by the screw conveying action of the guide plate 6 in cooperation with driving ribs running axially on the end cover 2 and on the rotating drum interior, and which is forced into the rotating drum interior by screw conveyors 7 from falling back into this packing chamber.
  • the rotary drum 1 is rotated and held in accordance with FIG. 1 via a ring gear 8 welded onto the circumference and a power take-off 9 derived from the vehicle drive, shown in dash-dot lines.
  • the drive units themselves are mounted in an auxiliary frame 10, which is set up for the special features of the actual useful structure, so that a standard truck chassis can be used.
  • the known storage of the rotating drum on the chassis described at the outset is characterized by a trouble-free interplay between the rotating drum, which is to be regarded as a rigid structure, and the cover held by the chassis or subframe even when the chassis twists, as occurs, for example, on uneven terrain can since it is a three point bearing.
  • the rear bearing of the rotating drum via a large ball bearing 11 with its outer ring attached to a lower carrier 12 has already become known (DE-GM 7 132 410) and has the advantage of making optimum use of the profile light width limited by road traffic regulations for the rotating drum diameter can. It has the storage of the end cap, the storage of its opening cylinder and the storage of the lid lock on arms independently attached to each other on the outer ring of the large ball bearing, which makes a relatively heavy design of the large ball bearing required.
  • the object underlying the invention is seen in the outer ring of the large Ku to use gel bearings to close a power circuit for the rotary drive, the rotary drive in particular becoming insensitive to torsion of the chassis and thus protecting its drive pinion, and furthermore the advantageous properties of the known refuse vehicles are retained, such as optimal use of the largest, clear diameter of the large ball bearing and the three-point bearing of the rotating drum.
  • the carrier Since, according to the invention, the carrier produces the frictional connection, it is essential in a further embodiment of the object of the invention to make it particularly stable or, in turn, torsionally rigid.
  • the carrier is designed as a box girder tangent to the outer ring of the large ball bearing on three sides, each with a side wall part, which encompasses it overall and has a longitudinal extension.
  • This configuration of the carrier as a box carrier with three-sided, tangent attachment to the outer ring of the large ball bearing forms an additional, advantageous stiffening of the latter and relieves it of the absorption of the forces for the lid holder and lock.
  • the design of the box girder according to the invention provides much more favorable conditions with regard to the force components, so that the large ball bearing can be made lighter. Compared to the known rotary drum garbage trucks, a reduction in the weight of the overall structure can also be achieved due to the more favorable force relationships. Due to the frictional connection of the box girder and drive, no torsional forces are transmitted to the subframe and the chassis to drive the rotating drum, which could lead to breakage.
  • the container 20 is mounted on a large ball bearing 22 in a closed two-part box carrier 23.
  • This box girder consists of an upper and lower part, which are connected to each other.
  • the lower part of the box girder 23 is horizontally movable about an axial support pin 33 directly on a plate 34 of the subframe, which is fixedly connected to the chassis 21, whereby the bearing forces of the collecting container 20 or the rotating drum are introduced directly into the chassis 21.
  • the drive and pressing forces are also introduced into this box girder 23.
  • the former are received via drive means flanged directly onto the lower part of the box girder 23, in the example shown via a separate drive motor 24 for the ring gear 25 welded to the circumference of the collecting container 20.
  • the pressing forces, which originate from the guide plate attached to the end cover 26, are transmitted to these via mutually complementary locks 27, one component of which is rigidly connected to the lower part of the box girder 23.
  • the drive for the ring gear 25 it is also conceivable and within the scope of the invention to drive it via a flexible coupling from a power take-off of the vehicle drive.
  • the collecting container 20 or the rotating drum which is driven by the pinion 31 mounted on the lower part of the box carrier 23, forwards the torque M t via the garbage to the guide plate, which is firmly connected to the cover 26.
  • the cover 26 in turn transmits the torque to the centering 32 of the box girder 23 connected to the lock, as a result of which the moments cancel each other out and are not passed on to the chassis frame 21.
  • the weight resulting from the dead weight of the body and from the payload is indicated vectorially with G.
  • the tooth engagement point i.e. the point at which the pinion 31 engages in the ring gear 25, in such a way that it lies close to the large ball bearing 22 so that the forces acting on the rotary drum 1 can practically exert no torsion and corresponding Vibrations do not even occur.
  • the arrangement of the tooth engagement point 31/25 with respect to the axial support pin 33 also acts towards the drum side, while the large ball bearing 22 is arranged towards the rear side. The forces exerted by the pinion 31 via the ring gear 25 on the rotary drum 1 thus do not increase the bearing pressure in the large ball bearing 22, but rather can be absorbed by the axial support pin 33.
