Definitions
- the invention relates to a cylinder crankcase of an internal combustion engine with the features of the preamble of claim 1.
- a cylinder crankcase of an internal combustion engine with several cylinders which has lateral stiffening elements in the form of longitudinal and high profiles. These hollow profiles are integrated into the cylinder crankcase in the casting. There are laterally a plurality of longitudinal profiles and a high profile provided on each base bearing, wherein the longitudinal profiles extend in the machine longitudinal direction and the high profiles follow the profile of the side wall of the cylinder crankcase, i. from the top first parallel to the cylinder direction and widened in the area of the crank chamber to the outside.
- the cavities of the profiles are designed to flow through.
- the object of the invention is in contrast to provide a cylinder crankcase with a stiffening structure of longitudinal and high profiles, in which a cylinder-like storage of a lateral camshaft is feasible.
- crankcase according to the invention is characterized in that a lateral camshaft is mounted below the hollow upper longitudinal profile and that the hollow high profile in the region of the bearing of the camshaft is divided into two, wherein the Longitudinal profiles run in the machine longitudinal direction and the high profile the course of the side wall of the
- Cylinder crankcase follow i. from the top first parallel to the cylinder direction and widened in the area of the crank chamber to the outside.
- a lateral camshaft bearing below the longitudinal profile and not outside the longitudinal profile there is the advantage of a narrow engine design because the camshaft does not substantially increase the engine's outline, but one is limited in determining the height of the center of the camshaft, i. the vertical position, not free. Since, in the plane spanned by two adjacent longitudinal profiles, the high profiles in each basic plane run perpendicular to these, the high profile is interrupted in the case of a camshaft arrangement below a longitudinal profile.
- the high profiles are arranged as well as the bearings of the camshaft in the basic levels, i. E.
- the high profile in the region of the camshaft bearing is divided into two, so that a continuous flow connection remains as constant as possible cross section and thus a uniform or symmetrical loading of the high profile occurs in bending or torsion of the cylinder crankcase.
- the space in which the camshaft moves may also be formed as a longitudinal profile and thus represents a second longitudinal profile below the upper. In this way, for manufacturing a one-piece casting core for the stiffening structure of vertical and longitudinal profiles can be used, which is significant Advantages in the production costs and the quality or tolerance of the position of the individual casting cores to each other results.
- a subsection of the split high profile is in each case
- the high profile is divided by closure elements in at least one upper and one lower cavity.
- closure elements By the introduction of closure elements, the cavities of the longitudinal and high profiles can be easily divided into two separate sections to guide different media therein, but without losing the advantage of a common casting core, which is easy to manufacture and allows accurate Gußrohmaschine by its inherent stability.
- a lower cavity of the longitudinal and high profiles is in communication with an oil chamber of the cylinder crankcase and serves as a pressure oil line or line for crankcase ventilation.
- transmission elements of a valve drive are arranged on the side of the cylinder crankcase, on which the bearing of the camshaft is arranged, in an upper cavity of the high profile and / or in the longitudinal profile. Since the camshaft is mounted in or below a longitudinal profile associated with the upper longitudinal profile, ie both profiles are filled with lubricating oil or oil mist, it is advantageous to use these spaces for the transmission elements of the valve train such as pushrods. As a result, the outline of the internal combustion engine or the crankcase is not substantially increased despite the longitudinal, high profiles, a lateral camshaft and the ram drive.
- FIG. 3 is a casting core of the camshaft side of the cylinder crankcase in a perspective view
- Fig. 4 is a casting core of the camshaft opposite side of the cylinder crankcase in a perspective view
- Fig. 5 is a casting core of the camshaft opposite side of the cylinder crankcase in a side plan view.
- a cylinder crankcase 1 with a plurality of cylinders 2 and a crank chamber 3 is shown.
- a base 4 In each case between two cylinders 2 is located in Kurbel syndromem 3 a base 4.
- a base 4 In the transition from the cylindrical upper part of the
- Cylinder crankcase 1 to the crank chamber 3 is on the outside of the cylinder crankcase, a cavity 5, the so-called camshaft bearing lane, arranged in which a camshaft, not shown, is mounted.
- This cavity 5 is formed as a longitudinal profile.
- another upper longitudinal profile 6 which serves for longitudinal reinforcement of the cylinder crankcase 1 and in particular for stiffening the cylinder deck 7 and is also made hollow.
- 6 plunger not shown a valve actuator housed in this longitudinal profile.
- the guides 8 and the passages 9 for the plunger are provided in the cylinder crankcase 1.
- a stiffening, hollow longitudinal profile 10 is also arranged.
- the longitudinal profiles 10, 11, 12 are arranged, wherein the arranged at the lower end of the cylinder crankcase longitudinal profile 10 corresponds to the longitudinal profile on the camshaft side. Since neither camshaft nor tappets are provided on this side of the cylinder crankcase, the longitudinal profiles 11, 12 are simpler, i. rectilinear without cross-section jumps.
- a coolant flows from the longitudinal profile 11 formed as a coolant distributor line into the cooling jacket 14 around the cylinders 2.
- Camshaft bearing passage 5 is shown over a whole and two adjacent half cylinders 2. From the longitudinal profile 6 lead over the cavity of the camshaft bearing passage 5 hollow high profile 15 to the lower edge of the cylinder crankcase 1. The high profiles 15 are in the basic storage plane between two cylinders. 2 arranged.
- the camshaft not shown, is mounted in camshaft bearings 16, which are in turn connected in areas in front of and behind the cutting plane of the figure with the cylinder crankcase 1 by casting.
- the lubricant supply for the camshaft is carried by the holes 17 in the camshaft bearing 16.
- the plunger, not shown for actuating the gas exchange valves are guided in the guides 8 and protrude through the passages 9 from the cylinder crankcase 1 in the cylinder head, not shown.
- the high profiles 15 are interrupted in their rectilinear course from the longitudinal profile 6 to the lower edge of the cylinder crankcase 1 and extend in the region of the camshaft bearing 16 in two parts around the camshaft bearing. Seen in the direction of the camshaft bearing passage 5, a part of the cavity of the high profile 15 extends in front of and a part behind the camshaft bearing 16. In this way, a continuous, almost constant large Str ⁇ mungsquerites is given from top to bottom.
- the casting core 18 of the stiffening structure of the cylinder crankcase 1 is shown in an oblique view to the camshaft side from the outside.
- the casting core 18 is composed mainly of the sections for the high profile 15 and the longitudinal profiles 5 ⁇ , 6, 10 ⁇ together.
- the guides 8 ⁇ consist of a subsequently drilled sprue, they are formed in the casting core, which consists for example of molding sand, as a cavity or gap.
- the casting core 19 of the stiffening structure of the cylinder crankcase 1 is shown in an oblique view from the inside to the camshaft opposite side.
- the casting core 19 consists primarily of sections for the high profile 15 ⁇ and for the longitudinal profiles 10 ⁇ , ll 1 together.
- the passages 13 are mounted for the coolant.
- the from the casting core outstanding pin 20 result in the finished cylinder crankcase breakthroughs and are used during casting as a holder and connection of the various casting cores with each other and the finished cylinder crankcase as a transfer point for example, coolant from the cylinder crankcase to the cylinder head.
- the casting core 19 of FIG. 4 is shown in a side view from the inside to the outside in the cross-machine direction.
- the transition point 21 from the high profile 15 ⁇ to the upper longitudinal profile 11 ⁇ shown.
- the profile structure of longitudinal and high profiles is cast around a casting core 19 on the side opposite the camshaft, but the cavities resulting from the casting core are divided by closure elements at the transition point 21 into two separate cavities.
