Embodiment Construction

[0024] The illustration in FIG. 1 shows an isometric view of a part of the housing of a hub transmission 10 . In the viewing direction selected for the illustration, the end face 12 of the housing of the hub transmission 10 is substantially shown. On the end face 12 there are—as a conventional measure for better cooling of the hub transmission 10—radially oriented and evenly spaced ribs which function as cooling ribs 14 . These ribs enlarge the heat-dissipating surface of the hub transmission 10 and correspondingly lead to better cooling than cooling with the flat end face 12 . The component 16 on the end face of the transmission can also be seen on the rear side. The interior of the hub transmission 10 is not shown.

[0025] figure 2 The illustration in the figure shows an embodiment of the hub transmission 10 proposed here based on a part of the hub transmission 10 shown in FIG. 1 . In contrast to the situation in FIG. 1 , the proposed hub transmission 10 and its housing...

Abstract

The invention relates to a wheel hub transmission (10) comprising an outer surface that acts as an end face (12) which has radially oriented cooling fins (14) at a regular distance from one another, and comprising a cover (18) which covers the cooling fins (14) at the end face and which has a central opening; the cover (18), along with pairs of adjacent cooling fins (14), defines a plurality of radially oriented cooling ducts (20).

Description

technical field [0001] The invention relates to a hub transmission device. Such transmissions are known and are sometimes also referred to as mining truck transmissions. Background technique [0002] Hub drives get very hot during operation. Due to the compact construction, it is difficult to install components for cooling on the hub drive. Consequently, either the hub transmission runs too hot under load, or the hub transmission is only operated partially loaded. [0003] Today, the hub drive is only cooled by free convection as well as the running relative air flow and the air vortices created by the rotation. In order to increase the heat dissipation surface, ribs are formed on the face-side surface of each hub gear. Contents of the invention [0004] The object of the present invention is to specify a further embodiment of a hub transmission, in particular an embodiment of a hub transmission which is characterized by an improved cooling effect. [0005] According ...
