Embodiment Construction

[0037] The same reference numerals denote the same or similar type of components in the following drawings.

[0038] figure 1 A simplified schematic diagram of a motor vehicle 12 with a compressor 10 is shown. The delivery vehicle 12 is driven by a drive engine 20 . The drive engine 20 drives the compressor 10 via a transmission 26 , which draws in air from an air filter 24 and supplies compressed air to a compressed air supply 22 . The transmission 26 has a gear ratio i less than one and a drive shaft speed n equal to the engine speed 驱动 Greater than the driven shaft speed n which is the same as the compressor speed 输出 . As a result, the compressor speed and the engine speed differ by a fixed factor i. The drive engine 20 , the transmission 26 and the compressor 10 driven by the drive engine 20 through the transmission 26 together constitute a system. Typical transmission ratios in which it is particularly preferred to use the compressor according to the invention are b...

Abstract

The invention relates to a compressor (10) for supplying compressed air to a utility vehicle (12), said compressor comprising a drive engine (20), wherein the compressor (10) is driven by the drive engine (20) via a transmission (26) having a transmission ratio that is less than one and comprises a piston chamber (14), a clearance volume (16) and a valve device (18) for switching the clearance volume (16). According to the invention, the valve device (18) is configured in such a manner that the air stream supplied by the compressor (10) can be reduced to a value that is different from zero by activating the clearance volume (16). The invention further relates to a method for controlling a compressor (10) for supplying compressed air to a utility vehicle (12).

Description

technical field [0001] The invention relates to a compressor for supplying compressed air to a cargo vehicle having a driving engine, wherein the compressor is driven by the driving engine through a transmission with a transmission ratio of less than one, and the compressor comprises a piston chamber, a clearance and a Valve device for closing clearance. [0002] The invention furthermore relates to a method for controlling a compressor for supplying compressed air to a cargo vehicle with a drive motor, wherein the compressor is driven by the drive motor through a transmission with a transmission ratio of less than one, and the compressor comprises a piston chamber, a residual Gap and valve device for connecting the gap. Background technique [0003] In order to be able to meet the compressed air requirements of the sub-systems of modern trucks, the compressors belonging to the compressed air supply have a reduced transmission ratio. The speed of the drive shaft at the sam...
