Definitions
- the invention relates to a camshaft drive of a multi-cylinder V-engine according to the preamble of claim 1.
- a camshaft drive for a V-engine is known. in which an intermediate gear meshing with a crankshaft gearwheel drives a camshaft via a further gearwheel drive, which in turn also drives the second camshaft with gearwheels.
- Such a camshaft drive can only be used for racing engines due to the high noise emission, but is unsuitable for production vehicles.
- a flywheel 3 On a crankshaft 2 of an 8-cylinder V-engine mounted in a crankcase 1, a flywheel 3 is screwed to the output-side end face with several screws 4.
- a camshaft drive emanating from the crankshaft 2 is arranged between the flywheel 3 and the final bearing 5. It consists of a meshing with a crankshaft gear 6 gear 7 of an idler gear 8 and two chain drives driven by the idler gear 8 to the four camshafts 11, 12, 13, 14 assigned to the two cylinder rows 9, 10, each of which has a double sprocket 11 ', 12 ', 13', 14 'wear.
- the double sprockets 11 ', 12' are driven with a double roller chain 15 by a double sprocket 16, the double sprockets 13 ', 14' with a double roller chain 17 by a double sprocket 18.
- the double chain wheels 16, 18 are formed in one piece and fastened on the hub sleeve 19 of the gear 7.
- an oil pump 20 which supplies hydraulic turning devices 21, 22 on the camshafts 11, 13 with hydraulic pressure. With the twisting devices, the rotational position between the camshafts 11, 13 and their associated sprockets 11 ', 13' is changed.
- a pump wheel 24 is fastened on a hollow hub 23 of the gear wheel 7.
- the oil pump 20 is covered by a pump cover 25 which, together with a cover disk 26 screwed to it, forms the pump housing.
- a bearing sleeve 27 is fastened in the pump cover 15, on which the intermediate wheel 8 is mounted and through which the oil supply to the oil pump 20 takes place.
- crankshaft 2 to idler gear 8 has a ratio of 1: 2, but the sprocket ratio from idler gear 8 to camshafts 11, 12, 13, 14 is 1: 1, camshafts 11, 12, 13, 14 also run half crankshaft speed around.
- the main oil pump 30 is driven by the crankshaft 2 with a chain drive 31. It sucks in lubricating oil from the oil pan 32 and pumps it with a pressure of approx. 3 bar to the bearing points of the internal combustion engine to be lubricated. A partial flow of this oil passes through the central bore of the bearing sleeve 27 to the oil pump 20, which increases the oil pressure to approximately 8 bar and gives it to the hydraulic camshaft twisting devices 21. Since this hydraulic pressure is very high, the camshaft rotating devices 21 can be made small-volume in the desired manner.
- the chain drive 31 is formed by a chain wheel 33 fastened to the crankshaft 2, a chain 34 and a chain wheel 35 fastened to the main oil pump 30.
- the chain wheel 33 is composed of two half-shells which were formed by radial blasting of a cylindrical chain wheel hub. In a groove 36 of the crankshaft 2, the two half-shells of the chain wheel 33 are joined together again at their break point and held axially.
- a tension ring 37 mounted on the chain wheel 35 holds the two half-shells radially together.
- the sprocket 33 is locked in the circumferential direction with a fitting sleeve 38 which is fixed in the crankshaft 2 and which was pushed through during assembly through an aligned bore 39 of the flywheel.
- the ring gear 40 of the chain wheel 33 and thus the entire chain drive 31 is located centrally between the two double chain wheels 16, 18 of the camshaft drive.
- crankshaft gear 6 is pushed over the smoothly turned outer surface 41 of the crankshaft 2 until it bears against the clamping ring 37. At this seat it is shrunk onto the crankshaft 2.
