Engine block for motorcycles

The innovation relates to an engine block for motorcycles, consisting of a housing and one below the Housing sealingly and detachably attached oil pan, the housing having incorporated lubricant channels, which emerge above the oil pan, ind with a filter are connectable.

In the known engine blocks for motorcycles, the oil pan is arranged below the housing and with the same connected by screws using a gasket. Lubricant channels are incorporated into the housing, over which the oil in the oil pan is sucked in by a pump and fed to the corresponding lubrication points. From here the lubricant flows back into the oil pan. To avoid that in particular in the oil When abrasion reaches the lubrication points, the oil sucked in by the pump is conveyed through a filter in the lower Area of the housing is arranged in front of the lubricant feed channel. To accommodate the mostly tubular Filter, the housing has an opening on one side into which the filter is inserted and on the outside via a flange is attached to the housing. The inner end of the filter is received by a cylindrical recess which a channel for the supply and discharge of the lubricant

has. This known arrangement has the disadvantage that when changing the oil filter on the side of the housing a lot of space is required, which is through the exhaust pipe and / or a panel is blocked. To change the filter, the exhaust and / or the cladding must always be removed, which is not only cumbersome but also time-consuming.

The innovation is therefore based on the task of designing an engine block for motorcycles so that the oil filter is exposed is accessible and can be inserted or replaced without removing other parts.

To solve this problem is proposed according to the innovation gen that an annular intermediate piece is sealingly arranged between the housing and the oil pan, which is also Has lubricant channels, on the one hand with the lubricant channels of the housing are connected and on the other hand in the area of an outside front on the intermediate piece attached filter open.

Due to this design, the filter is freely accessible and can therefore be used or replaced easily and in a very short time will. This external arrangement of the filter provides additional cooling of the oil or lubricant achieved. Due to the fact that the lubricant channels are led to the outside through the intermediate piece, it is without Difficulties are possible, in front of the filter in a special connector, the lines for a subsequent installation To attach oil cooler.

Heinere features of the innovation are in claims 2-8 disclosed.

The innovation is explained in more detail below with reference to an embodiment shown in a drawing. Show it
Fig. 1 is an elevation view of an engine block according to

the innovation,

Fig. 2 is a plan view of the annular intermediate piece of FIGS. 1 and

Fig. 3 is a side view of the annular intermediate piece of Fig. 1.

Of an engine block of a motorcycle, the housing 1 is only indicated in Fig. 1 of the drawing, which has a cylindrical recess 2 in its lower, inner region, in the base area of which there are two lubricant channels 3.4 open. The lubricant channel 3 is connected to an oil pump, not shown, during the Lubricant channel 4 leads to the lubrication points of the engine, also not shown.

On the underside of the housing 1, an annular intermediate piece 5 is provided which, together with an oil pan, is fastened to the housing 1 by means of indicated screws 7. A seal (not shown) is arranged on both sides of the intermediate piece 5. The intermediate piece 5, which

for example consists of a light metal alloy, has an inwardly and upwardly directed projection 8, which is provided with a lateral collar 9 at its upper end. This collar 9 has a circumferential groove 10 for receiving a sealing ring 11 (Fig. 3). The collar 9 is received in a sealing manner by the recess 2. The projection 8 can be

I 15 channel 16 is the lubricant from the oil pump to FiI-I ter 15. Another lubricant channel 17 leads from the pin 14 through the web 12, the intermediate piece 5 and the projection 8 to the collar 9, which merges into the lubricant channel 4 of the housing 1 here. Via this channel 17 the 20 lubricant from the filter 15 to the lubricant channel 4 and from here to the lubrication points, not shown.

Due to the aforementioned arrangement, the filter 15 is located on the front side of the engine block, with the result that 25 the filter 15 is on the one hand easily accessible and on the other hand is acted upon by the airstream. This causes a additional cooling of the oil.
