Definitions
- the invention relates to a crankcase for an internal combustion engine, in particular for a boxer engine according to the preamble of claim 1.
- the object of the invention is therefore to design the screw connection of the two crankcase halves in such a way that the bearing screws can be brought close to the bearing bore for receiving the crank pin.
- the two crankcase halves are screwed at an angle, ie at an angle with respect to the central axis of the cylinder bore, the holes for the bearing block screwing can be brought closer to the bearing bore. So that the transverse forces occurring in the case of an oblique screw connection are eliminated, the parting plane of the two crankcase halves runs essentially at the same angle as the longitudinal axis of the bearing screws to the central axis the cylinder bores are aligned. In other words, the longitudinal axis of the bearing bolts runs essentially at right angles to the parting plane of the two crankcase halves, so that advantageously no transverse forces occur in the screw connection according to the invention.
- 1 is a schematic overall view of the crankcase of a combustion
- FIG. 2 is a plan view of the crankcase in the direction of arrow A in FIG. 1,
- Fig. 3 is a sectional view taken along the line II - II in Fig. 2 and
- Fig. 4 is a perspective view of a crankcase half.
- crankcase shown in the drawing for a 6-cylinder boxer engine consists of two crankcase halves without being restricted to this embodiment
- Each of the two crankcase halves 10 and 12 have a plurality of bearing sections 18 arranged one behind the other, hereinafter referred to as bearing seats, in which one half of a bearing bore 24 is formed for a crankshaft (not shown), the bearing bores 24 being assembled
- the screwing of the Bearing chairs 18 each have two bearing screws 26, 28, with which the two crankcase halves 10 and 12 are screwed at the same time.
- the division plane 30 of the two crankcase halves 10 and 12 extends at an angle, which is approximately 12 ° in the present case, with respect to a line 32 which is essentially perpendicular to the cylinder longitudinal axis 34.
- the longitudinal axes 36 of the bearing screws 26, 28 in turn run with respect to the cylinder longitudinal axis 34 at an angle a, which essentially corresponds to the angle ⁇ of the inclined parting plane of the two crankcase halves 10 and 12.
- the bearing screws 26, 28 are arranged obliquely with respect to the longitudinal axis 34 of the cylinder, the holes 37 for the bearing block screw connection can be brought closer to the bearing holes 24.
- the gas and mass forces exerted on the crankshaft during combustion can thus be safely absorbed and gaping of the bearing seats 18, in particular in the region adjacent to the bearing bore 24, is prevented.
- the longitudinal axes 36 of the bearing screws 26, 28 run at right angles to the parting plane 30 of the two crankcase halves 10 and 12, no transverse forces arise during the screw connection, which would otherwise have to be absorbed by additional positive connections.
- the screw heads 38 and 40 of the bearing screws 26 and 28 lying opposite and parallel to one another are supported on an outer screw surface 42 and 44 of the crankcase halves 10 and 12, the screw surfaces 42, 44 being approximately at the level of the lower end of the cylinder bores 14 , 16 are arranged.
- Screw heads 38 are supported on the screw surface 44 of the crankcase half 12 are screwed into the other crankcase half 14 in a threaded blind hole.
- the bearing screws 28, the screw heads 40 of which are supported on the outer screw surface 42 of the crankcase half 14, are in the opposite crankcase half 12 with a thread screwed blind hole.
- seven storage chairs 18 are provided for the 6-cylinder boxer engine.
- the cutouts 46, 48 belong to the crank chamber, the openings 50 are water-carrying channels which are supplied with cooling water via corresponding connections 52.
- the opening 54 arranged below the bearing bore 24 in relation to the installation position of the boxer engine serves to receive an intermediate shaft (not shown) for driving the camshafts arranged in the cylinder head.
- a channel 56 which leads to a bearing bracket 18, serves to supply lubricating oil to the crankshaft, bearing shells 58 also known from the prior art being arranged in the individual bearing brackets 18.
- a channel 60 starting from the bearing bore 24 and leading to the cylinder bore 14, is used for cooling the spray oil, not shown, for the pistons.
- an oil filter 62 is screwed to the crankcase and is used to clean the lubricating oil.
