Definitions
- the invention relates to an internal combustion engine with an engine block, one on the engine block rotatably mounted crankshaft, at least one spaced parallel to the crankshaft on Engine block rotatably mounted camshaft and the crankshaft with the Camshaft connecting spur gear, the spur gear being at least one non-rotatably connected camshaft gear and a rotatably connected to the Crankshaft connected crankshaft gear and an idler gear arrangement with few has an intermediate wheel which is arranged and designed such that it is a Power transmission connection between the camshaft gear and the crankshaft gear manufactures, wherein the idler gear one the at least one idler gear bearing intermediate wheel carrier, according to the preamble of claim 1.
- the thermal expansion of the engine block has no influence on the Support plate so that this thermal expansion does not affect the distance between the shafts of the idler gears mounted on the support plate.
- the backlash in the control transmission device essentially predetermined by manufacturing tolerances on the engine block and on the support plate and not adjustable or adjustable.
- the present invention is therefore based on the object of an improved To provide internal combustion engine of the type mentioned above, the the disadvantages mentioned above are overcome and an easy way of setting of the backlash is available.
- a first connection between the idler and the engine block is provided such that the idler gear around this first Connection is pivotable, and that spaced from the respective axes of rotation Camshaft, the crankshaft and the at least one intermediate gear a second Connection between the intermediate wheel carrier and the engine block is provided in such a way that the idler gear is at a predetermined angle around the first connection is pivotable and lockable in a predetermined position.
- the first connection is aligned with an axis of rotation one of the idler gears.
- To set the backlash between one the first connection is aligned with the camshaft-side intermediate gear and the camshaft gear with the axis of rotation of the intermediate gear meshing with the crankshaft gear.
- the second connection has the following, a threaded hole in the engine block along a segment of a circle with a radius around the first connection Elongated hole in the intermediate wheel carrier, the radius being a distance between the first Connection and the threaded hole corresponds, and one through the slot in the Threaded bolt engaging threaded bolt.
- the intermediate wheel arrangement has three intermediate wheels on, namely an intermediate gear on the camshaft side, soft with the camshaft gear meshes, an intermediate gear on the crankshaft side, which meshes with the crankshaft gear, and a center idler gear, which with the camshaft side idler gear and the intermediate shaft on the crankshaft combs.
- the crankshaft wheel is expediently fastened to the crankshaft with a freewheel.
- the intermediate wheel carrier is made of a sintered material or Made of aluminum alloy.
- FIGS. 1 and 4 trained spur gear for an otherwise not shown Internal combustion engine with an engine block 11 (FIG. 4) comprises a crankshaft wheel 10, which with a crankshaft, not shown, rotatably in one direction and in the corresponding to another direction is connected to a freewheel, a water pump wheel 12, which is connected to a drive shaft of a water pump, not shown, two Camshaft gears 14 and 16, which have respective camshafts, not shown are connected, and an intermediate wheel assembly 18, which is a power transmission Establishes connection between the crankshaft gear 10 and the camshaft gear 14.
- the intermediate wheel arrangement comprises 18 three intermediate wheels 20, 22 and 24, which are all rotatable about a respective axis of rotation 26, 28 and 30 are arranged on an intermediate wheel carrier 32.
- the crankshaft side Idler gear 20 meshes with crankshaft gear 10
- the idler gear on the camshaft side 22 meshes with the camshaft gear 14
- the central idler gear 24 meshes with the crankshaft-side idler gear 20 and camshaft-side idler gear 22.
- the intermediate wheel carrier is connected to a first connection 34 shown in FIG Intermediate sleeve 36, a threaded bore 38 and a threaded bolt 40 on the engine block 11 connected such that when the threaded bolt 40 is not tightened, the intermediate wheel carrier 32 is pivotable about this connection 34.
- the axis of rotation of this pivot point is aligned with the axis of rotation 26 of the crankshaft-side idler gear 20.
- an elongated hole 42 in the intermediate wheel carrier 32 formed, which runs along a circular arc segment 44.
- a threaded bore not shown formed, which is also on the circular arc segment 44, so that at one predetermined position of the with the first connection 34 on the engine block 10 still pivotally attached intermediate gear carrier 32 this threaded hole with the slot 42nd is aligned and a threaded bolt 46 extends through the slot 42 into the Threaded hole can be screwed.
- the intermediate wheel carrier 32 is limited by the dimensions of the elongated hole 42 are pivotable about the first connection 34.
- the Elongated hole 42, the associated threaded bore and the threaded bolt 44 form a second Connection 48 of the idler gear 32 to the engine block 10.
- By a corresponding pivoting is a backlash between the camshaft side Intermediate gear 22 and the camshaft gear 14 adjustable. By tightening the Threaded bolt 40 and 46 is the idler gear 32 in a desired position corresponding backlash can be locked.
- the spur gear transmission designed according to the invention is assembled as follows: First, the crankshaft gear 10 is fastened to the crankshaft with the freewheel. After that the camshaft sprockets 14 and 16 are loosely attached to the camshafts. As Next, the idler gear 32 with the preassembled idler gears 20, 22 and 24 pushed on and the threaded bolts 40 and 44 are only loosely screwed in not tightened yet. By correspondingly pivoting the intermediate wheel carrier 32 a desired backlash is set about the axis of rotation 26. Then the Threaded bolt 40 and then the threaded bolt 44 tightened so that the first and second connection 34 and 48 is established or locked. Eventually they will Camshaft gears 14 and 16 tightened on the respective camshafts.
- camshaft sprockets 14, 16 are first loosely attached and that Crankshaft gear 10 has a freewheel can when inserting the idler gear 32 the corresponding teeth of the wheels 22 and 14 or 20 and 10 with each other in meshing engagement can be brought without a fixed rotational angle relationship between the camshafts and the crankshaft by turning the crankshaft gear 10 or Camshaft gear 14, 16 is changed. This is because it works properly Operation of the engine is critical.
