Definitions
- the present invention relates to a portal axle for motor vehicles, in particular buses, with a housing in which a differential is arranged, which is connected to two axle shafts and with a suspension for connecting the housing to the vehicle, according to the preamble of claim 1.
- a driven axle arrangement for vehicles is known, with a central housing, with suspension elements which connect the central housing to the vehicle, with a main drive which is arranged in the central housing and which has a differential gear unit lateral drives, which are arranged at the outer ends of the central housing, with wheel hub units, which are each connected to the lateral drives, with a portal distance between a center telachse, a differential gear unit, which is arranged in the central housing and a longitudinal axis of the wheel hub units is provided, the suspension elements that connect the central housing to the vehicle are attached to housings of the side drives in an integrated manner and wherein the housing of the side drives , the central housing and the suspension elements are designed as a compact unit, with suspension elements which have essentially C-shaped arms as well as connection points for fastening the axle arrangement to the vehicle.
- suspension elements and the housings of the lateral drives are thus formed in one piece in this known portal axis, the essentially C-shaped arms being produced from a closed profile, the air springs and the ends of the arms which are distant from the central housing Have shock-absorbing damping elements.
- the object of the present invention is to design the spring supports or spring support halves for the portal axles of in particular buses in such a way that, on the one hand, a weight saving is achieved and, on the other hand, a cost reduction in manufacture is made possible.
- the spring supports consist of coreless, fully cast metal.
- the previously required inner core and the previously required core supports can be omitted.
- the area of curvature between the air spring and the portal housing is generally critical to strength. In this area, according to the invention, bumps are optionally attached at the top or bottom, which stabilize the spring support in this area.
- the spring support is formed as straight as possible. This is understandably only possible within the limits specified by the tire clearance.
- 1 is a perspective view of a conventional spring carrier
- 2 is a perspective view of a spring support according to the invention
- FIG. 3 different perspective views to 7 of spring supports according to the invention.
- Fig. 8 is a perspective view of a one-piece spring support for a coach.
- the portal axles for motor vehicles and in particular buses are well known to the person skilled in the art, so that only the parts essential for understanding the invention are shown in the figures.
- the portal axles have a housing in which a differential is arranged, which is connected to two axle shafts, and a suspension for connecting the housing to the vehicle, which has single or multi-part spring supports, which on the one hand on the housing and on the other hand via damping elements or Suspension elements are attached to the vehicle.
- FIG. 1 Part of a two-part spring support is shown in perspective view in FIG. 1, this spring support in a conventional manner having an inner core (not shown in the drawing) and two core supports 1, 2.
- a spring support is large in volume because it has an inner core.
- the support is weakened in its critical areas by the core supports 1, 2 used. From a casting point of view, these core supports cannot be omitted. Due to its design, such a spring support is relatively heavy.
- FIG. 2 shows a perspective view of a spring carrier according to the invention which is fully cast without a core. there the previously required inner core with its core supports is no longer required.
- the curvature area 3 between the air spring and the portal housing is generally skill-critical. In this area, bumps 4 are now optionally arranged below or above, which stabilize the component in this area. 2, the hump 4 is indicated on the underside.
- FIG. 3 shows a side view of a spring support according to the invention in a perspective view and FIG. 4 shows a top view.
- FIG. 5 shows an end view of the spring support according to the invention and
- FIG. 6 shows a partially cut-away side view.
- FIG. 7 shows an illustration similar to that in FIG. 2 and
- FIG. 8 shows a one-piece spring support according to the invention, i. H. as a coreless, fully cast component without an inner core and without core supports, which is particularly suitable for use on coaches.
- a coreless fully cast spring carrier for the portal axles of buses has a weight saving of approx. 20% per carrier, whereby the elimination of the inner core and core supports enables cheaper production. At the same time, the advantage of an improved area moment of inertia is achieved.
