The brakes of brake force, the piston pump for filling compressed air storage device and the drive with specific rotation speeds driving piston pump
Dynamic device.The invention further relates to a kind of method for filling the compressed air storage device of such compressed air system.
Background technology
Application field of the invention is extended on the vehicle equipped with motor, and brakes is provided with these vehicles,
In the brakes, brake lining is forced into the brake disc of wheel by compressed air-driven, to brake the wheel.So
Brakes generally have produce compressed air piston compressor.Here, piston compressor is generally or by the special of oneself
Driven with drive device or for example driven by the identical motor of driving vehicle.Due to being activated sometimes for volume flow high
Brake apparatus, and compressor can not necessarily provide these volume flows, so compressor will not be used directly to triggering braking
Device, but for example pass through what is electrically or pneumatically manipulated for filling compressed air storage device, after the compressed air storage device
The opening of valve drives brake.Thus, for example being coupled in compressed air system after braking procedure or other are activated
Pressure air consumer after or in the case where compressed air is flowed out due to leakage, to compressed air storage device
Filling is especially necessary.
It is general in the prior art, in order to fill compressed air storage device, piston pump is without transmission ratio
In the case of for example by the internal combustion engine drives of vehicle.Especially, piston pump has and explosive motor identical rotating speed.So
And, because the abrasion of piston pump is relevant with the cumulative duration that it is manipulated, in other words because its service life is manipulated with it and held
The continuous time is inversely proportional, it is desirable that only in time period upper-pilot piston pump as short as possible.
The content of the invention
Task of the invention is to realize a kind of compressed air system, and in the compressed air system, piston pump is as low as possible
Abrasively be used to fill compressed air storage device.
From the compressed air system according to claim 1 preamble this is solved with reference to the feature of its characteristic
Task.Following dependent claims illustrate advantageously expanded configuration of the invention.Introduce in claim 8 involved in the present invention

Monitor the ambient temperature of vehicle, especially also resided in by the advantage of the temperature of the air of piston pumping, example
(therefore the drier of compressed air system may freeze and in the case of the zubzero temperature such as in the case of zubzero temperature
Do not work), make the rotating speed draw volume stream reduction in other words of compressor, so as to heat what is flowed through during aspiration procedure
Air.The lubricating oil temperature or the advantage of coolant temperature that monitoring is for example used in drive device or piston pump are, in profit
The rotating speed of piston compressor can correspondingly be reduced in the case of the exceedingly heating of lubricating oil or coolant.Therefore, can especially avoid
The damage of the piston compressor or drive device that are caused due to overheat.
Monitoring compressed air storage device inside air themperature advantage in particular, in that, be used as thermodynamics shape by knowing
The temperature of state parameter for example can be inferred that the particle of the air for wherein including while know the pressure being contained therein
Measure quality in other words.The triggering that the threshold value that the air quality such as less than determines before can then be used as activating piston pump is sentenced
According to.
Preferred embodiment of the invention, at least one Sensor Design into pressure sensor, it is described at least
One vehicle parameter is designed to the tire pressure of at least one wheel of vehicle or is designed to inside compressed air storage device
Air pressure or air quality or air capacity are designed to the air stream spilt from compressed air system due to leakage.
The advantage of tire pressure is checked especially to be obtained in these vehicles：In these vehicles, tire can be by compression
Air system is for example also inflated during travelling.Here, the decline of tire pressure can be required to compressed air storage device
Filled, that is, activated or accelerated piston pump.
Inspection compressed air storage device in air pressure in other words air quality check in other words due to leakage from
The volume flow spilt in compressed air system, equally can be used the speed activation of piston pump in other words of triggering piston pump
Criterion.
Measure of the invention, at least one of at least one Sensor monitoring compressed air system are improved according to one
The activity of pressure air consumer, such as parking brake or Aeroassisted system.Dress is consumed by monitoring the compressed air
Put the raising that can trigger the piston compressor rotating speed for thus needing.
As other vehicle parameters of the rotating speed for changing drive device it is also contemplated that such as firing key position, i.e.
Position of the firing key in ignition switch.Thus such information is derived：Vehicle is to prepare operation or go back in operation
It is that both are all non-.Additionally, in this respect it is also contemplated that the real-time accelerator pedal position and/or fired state of vehicle, this can be with
Determined by using sensor technology or signal processing technology.
For example can also be incited somebody to action in the maximum pressure of the restriction in reaching compressed air system by solution of the invention
The rotating speed of drive device changes to null value.Piston pump thus can also be completely switched off after compressed air is filled.Class
As, the measure in the control technology can also be used when other critical vehicle parameters are reached.
Measure of the invention is improved according to one, the drive device of piston pump is configured to explosive motor or motor or liquid
Pressure motor is configured at least one wheel of vehicle.Advantage therein is, by the existed, energy in terms of its rotating speed
The system being steered is used as drive device.
Measure of the invention is improved according to one, piston pump is connected on auxiliary actuator.This can be realized and driver
The parallel piston pump of use real, script, meeting purpose coupling.Such auxiliary actuator can for example be constructed
Into the axle stretched out from actuator housing.By the measure, piston pump also can be when transmission for vehicles be separated with drive motor
Driven.
Preferred embodiment of the invention, control data is designed to the gearshift request of drive device and/or rotating speed
Change request.Here, advantage in particular, in that, for example can be during travelling by improving the rotating speed and simultaneously of drive device simultaneously
The gear that reduction has been linked into is caused by speed changer in other words, rotational speed of driving unit, can be real relative to the gearratio of vehicle wheel rotational speed
It is existing, the raising of piston revolution speed can be realized in the case where car speed holding is constant.
The inventive process provides the parameter related to compressed air supply measurement and make the rotating speed of piston pump with should
The subsequent adaptation of parameter.
