Definitions
- the invention relates to a compressor which is connected by a gear ratio with a drive source.
- Commercial vehicle air compressors typically convert rotational motion provided by the drive source (motor) of at least one piston that moves up and down in a cylinder and compresses the air as it travels. This conversion is done by a connecting rod which is rotatably mounted with a connecting rod eye on the piston and which is mounted eccentrically rotatable with another connecting rod on a crankshaft.
- the crankshaft is rotated by a gear ratio of the drive source in rotation. The gear ratio is constant, so that the working speed of the compressor changes with the engine speed.
- a compressor has been developed.
- This has a crankcase, in which a crankshaft is rotatably mounted in a crank chamber.
- the crankcase includes at least one cylinder space in which a by a connecting rod eccentrically mounted on the crankshaft piston to a reciprocation can be excited.
- the crankshaft is connected to a drive source by a gear transmission having a modulus m by the gear arranged on the crankshaft engages the gear on the drive source.
- the axis of rotation of the crankshaft is offset against the central axis of the cylinder space by an amount dl which is an integer multiple of m / 2.
- the central axis of the cylinder space is understood to be the axis from which the center of the base area of the cylinder space extends perpendicular to this base area, along which the piston moves.
- the gear ratio of the transmission can be changed to a favorable range without having to make changes to the external dimensions of the compressor or to the drive source.
- the gear of the drive source does not need to be changed. If the gear of the drive source has a number Zi of teeth and the crankshaft meshing therewith has a number Z 2 of teeth, then the pitch of the axes of rotation of the gears is given by m * (Zi + Z 2 ) / 2, where m is the Modulus of the transmission is. This modulus is a measure of the size of the teeth.
- the claimed offset between the axis of rotation of the crankshaft and the central axis of the cylinder space is introduced, the number of teeth Z 2 of the gear on the crankshaft, and thus the transmission ratio of the transmission can be changed without changes to the drive source must be made.
- the number of teeth remains integer, so that consuming adjustment measures account for the gears.
- the claimed feature of the integer multiple of m / 2 is not interpreted purely mathematically, but also explicitly includes even distances dl, which differ from an integer multiple of m / 2 only so far that the gear of the crankshaft within the mechanical tolerances can intervene without changes to the size of the teeth for the purpose of transmitting power in the gear of the drive source.
- the transmission advantageously has a transmission ratio between 1 to 0.9 and 1 to 1.1 from the drive source to the crankshaft.
- Typical heavy-duty engines provide a gear with a modulus between 1.5 and 3.5 mm for driving a compressor.
- the gear ratio per tooth by which the tooth number Z 2 of the gear on the crankshaft is changed can be changed by 2 to 3%.
- the transmission ratio is greater than 1, ie Z 2 is smaller than Zi. Then the piston of the compressor moves faster. Given specifications for airflow per unit time (eg, 200 liters per minute at 12 bar system pressure and 700 rpm engine), less piston stroke in the cylinder is required to achieve this performance.
- the transmission ratio is greater than 1, ie Z 2 is smaller than Zi.
- Compressor can be made more compact. Because of the cramped space in the engine compartment of Kolbenhubraum is a constant bottleneck. Typically are only 360 to 400 cm 3 per cylinder are available.
- the pivotally mounted against the crankshaft connecting rod eye of the connecting rod is freely movable in a circle about the axis of the crankshaft. The wear due to bearing forces is then particularly low. Furthermore, this embodiment takes up very little space in the crankcase of the crankcase.
- the axis of rotation of the crankshaft against the central axis of the cylinder space by an amount dl between 1 and 5 mm, preferably between 2 and 3 mm, offset.
- the invention offers the advantage that compressors of a limited scope of power classes with a high common-mode component can be produced inexpensively. It is to adjust the power only the offset dl between the axis of rotation of the crankshaft and the center axis of the cylinder adapt.
- FIG. 2 shows the integration of a compressor according to the invention into a given engine compartment.
- FIG. 1 shows a schematic diagram of a compressor according to the invention.
- the crankcase 1.5 is a cylinder bore la. Its central axis is marked with X.
- a piston 2 moves in the cylinder bore. It is connected to the crankshaft 4 via a connecting rod 3.
- the connecting rod has two connecting rod eyes 3a and 3b.
- the upper connecting rod 3 a is rotatably supported against the piston 2.
- the lower connecting rod 3b is rotatably supported against a crank pin 4a which rotates with the crankshaft 4 about the central axis Y thereof. If the crankshaft 4 rotates, the lower connecting-rod eye 3b of the connecting rod 3 describes a circle about the central axis Y of the crankshaft 4.
- the axes X and Y run perpendicular to one another; the axis X runs in the plane of the drawing, the axis Y perpendicular to the plane of the drawing. However, both axes are shifted parallel to each other by an amount dl.
- the crankshaft 4 is rotatably supported against the part 5 of the crankcase 1,5. The effect of the parallel displacement dl is shown in the integration of the compressor in an engine compartment as shown in FIG 2.
- the engine block 9 is of fixed dimensions, which provides a predetermined gear 8 for driving the compressor.
- the gearwheel rotates about an axis Z, which is perpendicular to the plane of the drawing and has a distance A from the center plane X of the cylinder space running in the plane of the drawing.
- the crankshaft 4 is of a gear 7 driven that engages the gear 8 on the engine block 9.
- This gear 7 rotates about the axis Y, which is the axis of symmetry of the crankshaft 4 and is perpendicular to the plane of the drawing.
- the axes Y and Z have a distance B from each other which is smaller than the distance A. Therefore, the gear 7 has a number Z 2 of teeth, which is smaller than the tooth number Zi of the gear 8 on the engine block 9. The gear 7 thus rotates faster than the gear 8.
- the compressor ejects a larger volume of air per unit time. This change was made without having to change the size and shape of the compressor. Also, the flange 6, with which it is mounted in the engine compartment, is located in the same place as in a compressor according to the prior art, the gear 7 was the same size as the gear. 8
