Abstract

Lubricating device (10) for a refuse collection vehicle, comprising at least one application means (12) for applying a static-reducing lubricant to at least a portion of at least one inner wall of the refuse collection vehicle.

Description

The present invention relates to a lubricating device for refuse collection vehicles.

Generic waste collection vehicles have a collection container for receiving the contents of waste collection containers (groupage) and often a loading plant, in which the groupage is previously crushed or compacted. Typically, such a loading plant consists of a loading pan and a discontinuous compression mechanism, which presses the grouped into the loading pan groupage into the collection.

Often waste collection vehicles also have a collecting container in the direction of the cab limiting inner wall, which is displaceable within the collecting container. As a result, the loading space of the collecting container, for example. be increased after a compression stroke, thereby making room for more groupage.

A problem with such refuse collection vehicles is that with each compression stroke the static friction between the groupage and the inner walls of the collection container and / or the charging trough must be overcome, which leads to an increased energy consumption.

The object of the present invention is therefore to provide a lubricating device with which the static friction between the groupage and the inner walls of a refuse collection vehicle is reduced and thus the energy consumption is reduced.

This object is achieved by a lubricating device for refuse collection vehicles with the features of claim 1.

Accordingly, the lubricating device according to the invention comprises at least one application means for applying a friction-reducing lubricant to at least a portion of at least one inner wall of the refuse collection vehicle, in particular within the collecting container and / or the loading tray. Thereby, the static friction between the moving groupage and at least a part of the contacted inner walls of the refuse collection vehicle can be reduced, which increases the energy efficiency of the compression mechanism used.

Advantageous embodiments of the invention will become apparent from the subsequent claims to the main claim.

Accordingly, the lubricant may preferably be applied either cyclically or continuously.

Moreover, it is conceivable that the at least one application means is attached to a movable component. As a result, the lubricant can be applied to a larger area of the inner walls.

Alternatively, the at least one application means may also be attached to an immovable component. This can be advantageous, for example, if the moving components of the refuse collection vehicle itself ensure distribution and application of the lubricant. This is especially true for continuous compression mechanisms that operate, for example, on the principle of a rotating drum or a screw compressor, but also for discontinuous compression mechanisms.

In a preferred embodiment, the at least one application agent is designed as a nozzle, in particular as a spray nozzle. As a result, the lubricant can be applied to an extended inner wall area without having to paint or contact it directly.

In an alternative embodiment, the at least one application means is designed as a brush. In particular, in the case that the at least one application means is attached to a movable component, such a design as a brush can be advantageous since it can simply contact and coat the corresponding inner wall region directly.

According to a further preferred embodiment, at least four application means are arranged in the respective edge regions of a movable wall delimiting a collecting container of the refuse collection vehicle, wherein the lubricant can be applied to at least a partial region of the inner walls of the collecting container enclosing the movable wall. Due to this particularly simple embodiment, the lubricant can be applied gradually with each displacement of the movable wall along the entire length of the collecting container.

Particularly preferably, in each case at least two application means are arranged along each edge of the movable wall in order to achieve a large-area cover of the collecting container inner walls with the applied lubricant.

According to an alternative embodiment, the refuse collection vehicle has a compression mechanism which operates continuously, for example on the principle of a rotating drum or a screw compressor, and an input opening, wherein the at least one application means is arranged in the region of the input opening and wherein the lubricant covers at least one subregion of at least one Inner wall of the refuse collection vehicle can be applied.

According to a further preferred embodiment, the refuse collection vehicle has a discontinuous compression mechanism, wherein the at least one application means is arranged in the working area of the compression mechanism and wherein the lubricant can be applied to at least a portion of at least one inner wall of the refuse collection vehicle.

Advantageously, the lubricant consists of water, a surfactant, a preferably biodegradable oil or a mixture of several of these substances.

Further features, details and advantages of the invention will become apparent from the illustrated with reference to the figure embodiment. It shows:

• 1 : The collecting container of a refuse collection vehicle with a preferred embodiment of the lubricating device according to the invention.

In the 1 is a preferred embodiment of the lubricating device according to the invention 10 shown in which several executed as spray nozzles application agent 12 on a wall 16 are arranged, which are movable within a collection container 14 a waste collection vehicle is attached. The wall 16 limits the collection container 14 towards the cab and settles along the collector 14 procedure (illustrated by a double arrow). As a result, for example, after a compression stroke by means of a discontinuous compression mechanism (not shown here) of the hold for the compacted groupage be increased in order to make room for more groupage.

Furthermore, along the four edges of the movable wall 16 several spray nozzles 12 arranged, which a friction-reducing lubricant on the four inner walls (here are only two inner walls 18a . 18b visible) can apply. This makes it possible, the static friction between moving groupage and the inner walls 18a . 18b of the collection container 14 reduce and increase energy efficiency during compression strokes and / or shifts of the wall 16 to increase.

By this arrangement, the spray nozzles 12 together with the movable wall 16 Step by step moves in the direction of the cab, which makes it possible for the interior walls 18a . 18b in the area occupied by groupage space are always completely covered by lubricant.

In general, the spray nozzles 12 be mounted on the side facing the groupage.

Alternatively, however, it is also conceivable that the spray nozzles 12 on the side facing away from the groupage and the cab facing side of the movable wall 16 are attached. That's how it works on the interior walls 18a . 18b applied lubricant can be used simultaneously, the friction between the movable wall 16 and the interior walls 18a . 18b of the collection container 14 which leads to a further improvement in energy efficiency. This applies equally to embodiments in which the at least one application means 12 mounted in the area of the loading pan as well as waste collection vehicles with a continuous compression mechanism.
