Problems solved by technology

However, this solution is currently not usually used in vehicles since the compressor is usually directly or indirectly driven by the internal combustion engine, significantly increasing the fuel consumption of the vehicle
Frequent use of the compressor naturally reduces the working life of the compressor

Embodiment Construction

[0014] In FIG. 1 , air bellows 1 , 2 represent the air suspension of a transaxle (not shown) of a vehicle 13 such as a truck. For vehicles with full air suspension, the truck's front axle (front axle) will have its own air bladders (not shown). Likewise, if the truck has a rear axle (not shown), separate air bladders (not shown) will provide air suspension for the rear axle.

[0015] In a basically known manner, the airbags 1 , 2 are connected to the air tank 4 of the truck via a solenoid valve group 3 . If the truck has a rear axle, its air bladder will also be connected to solenoid valve group 3. The same applies to the airbags on the front axle, if necessary. Although only two gas tanks 4 are shown in Figure 1, it is understood that the number of gas tanks may vary depending on the actual type of truck.

[0016] The air storage tank 4 is connected to the compressor 5 so as to charge the air storage tank with compressed air. The air storage tank 4 and the compressor 5 fo...

Abstract

In a vehicle (13) with air suspension (1, 2) comprising an air supply system (4) with a compressor (5) that is adapted to automatically charge the air supply system both when the pressure therein reaches a predetermined minimum pressure and when an air-consuming activity is initiated by an operator of the vehicle, an operator-operated control switch (12) is provided to separately trigger the compressor (5) to charge the air supply system (4) up to a predetermined pressure.

Description

technical field [0001] The present invention relates generally to a vehicle with an air suspension including a compressor, and more particularly to an arrangement for controlling the compressor of such a vehicle. Background technique [0002] In vehicles such as trucks with air suspension, a compressor is provided so that when the pressure in the air supply system reaches a predetermined minimum pressure and when an operator, such as the driver of the vehicle, requires air-consuming operations, such as raising the vehicle or An air supply system including an air tank and an air bladder is automatically inflated during load transfer between the vehicle's rear tagaxle and drive axle. [0003] US patent US 6171065 B1 discloses a vehicle with gas springs which can be filled with compressed air by means of a compressor operated by a control unit. [0004] In current vehicles, when the operator requests an air-consuming operation, such as raising the vehicle, for example by press...
