Abstract

A pressurised medium operating system, for a gearbox, clutch or brake, comprises a slave cylinder 10 pressurised by a pressure generating device, eg either by a master cylinder 4 or by a pump (101, fig 2). A pipeline between the master cylinder 4 and slave cylinder 10 comprises a flexible corrugated tube 11, eg bellows, which provides a thermal expansion joint and allows the system to fit in a given space. The corrugated tube 11 may be a metal or plastics bellows and may be connected into the pipeline by welding or push-fit connection. The corrugated tube 11 may be connected on both sides to a tube of the pipeline or, on the other hand, the corrugated tube may be connected directly on one side to the slave cylinder or master cylinder.

Description

1 2345099 A pressurised medium operated installation The invention relates
to A pressurised medium operated installation more particularly for operating clutches, brakes or gearboxes more particularly in the drive train of motor vehicles.
Pressurised medium operating installations of this kind are already known from the prior art. These have a pressure generating device, such as for example a pressurised medium master cylinder, and an operating element such as for example a pressurised medium slave cylinder, with steel tubes mounted therebetween with in part rubber hose connections to guarantee the fluid connection. Plastics pipelines are also known.
These connections between a pressure generating device and an operating element are unsatisfactory from the point of view of handling and temperature behaviour of the volume capacity. With regard to handling, rigid connecting elements only fit poorly in the structural space provided. The temperature behaviour of the volume capacity of in particular the system having a rubber hose part is particularly critical in the known systems since as the temperature varies so the volume capacity changes quite severely in parts.
Similarly parts having a metal-rubber part are unsatisfactory from the point of view of costs since the plastics hose parts are made pressure resistant through extremely expensive construction.
According to the invention the problem is solved in that with a pressurised medium operating installation more particularly for operating clutches, brakes or gearboxes, more particularly in the drive train of motor vehicles having a pressure generating device, such as for example a pressurised medium master cylinder, and an operating device, such as for example a pressurised medium slave cylinder, with a pressurised medium fluid connection therebetween, at least one part of the pressurised medium fluid connection is made from a corrugated tube.
It can also be advantageous if the entire pressurised medium fluid connection in the area of the pressure line for operation consists of a corrugated tube.
It is advantageous if the pressurised medium fluid connection consists at least of one part of a corrugated tube and at least one part of a pipeline. It isalso expedient if the corrugated tube is connected on at least one side to a pipeline This connection can be produced by adhesive, welding or soldering or by means of mechanical reforming, such as by way of a compressed connection. A sealing or sealed push-fit connection can also be used.
It can be expedient if at least one of these connections 25 is or are also used when the corrugated tube is connected on both sides to a pipe line.
It is particularly expedient if at least one of the master or slave cylinders is connected directly to the connector of the corrugated tube. Instead of the master cylinder a pressurised medium generating device such as for example a pump can also be provided with at least one valve on the output side for controlling the pressure.
- 3 It is also expedient if the master and slave cylinders are each connected directly to a connector of the corrugated tube.
It is also advantageous if at least the other of the master or slave cylinder is connected to a connector of the corrugated tube by means of a pipeline.
It is expedient with a pressurised medium operated installation according to a further idea according to the invention if the corrugated tube is made from metal.
It is thereby expedient if the walls of the corrugated tube have a substantially sinusoidal undulating path.
It is particularly expedient if the pressure generating device is a pressurised medium master cylinder.
Furthermore with another embodiment it can be expedient if the pressure generating device is a device with a pump, where applicable a pressurised medium accumulator and at least one valve.
It is also expedient if the slave device is a pressurised medium slave cylinder.
The invention will now be explained in further detail with reference to the drawings in which:
Figure 1 is a diagrammatic illustration of a first embodiment of installation according to the invention; Figure 2 is a diagrammatic illustration of a second embodiment of installation according to the - 4 invention; and Figure 3 is a view of a corrugated tube.
Figure 1 shows diagrammatically a pressurised medium operated installation 1, more particularly for operating clutches, brakes or gearboxes, more particularly in the drive train of motor vehicles. The pressurised medium operated installation 1 consists of a pressure generating device 2 which is designed for example as a hydraulic master cylinder or pressurised medium master cylinder with master cylinder piston 3 with slave cylinder 4. The slave cylinder 4 is foot-operated for example by a pedal or is operated automatically by an operating device. An operating device of this kind can be operated for example by an electric motor wherein the electric motorised operating device can be purposefully controlled by a control unit 5.
The pressurised medium operated installation also includes a slave device 10 which is connected to the pressure generating device by a pressurised medium connecting pipe, such as a pressurised medium fluid connection 11. The piston 12 of the slave device 10 operates the clutch of a motor vehicle for example within the gearbox bell housing 21 of a vehicle gearbox 20 which is mounted on the output side of a drive motor 22 in the drive train of a motor vehicle. The drive train is marked 23 and is only shown diagrammatically.
The pressurised medium fluid connection, such as pressurised medium pipeline 11 is formed as a corrugated tube in the area of the pressure line between the pressure generating device and slave device.
The connecting pipe 11 thus has at least one corrugated tube section which is connected for example on one side or both sides by means of pipelines and is connected to the pressurised medium generating device and the slave device.
Figure 2 shows a further variation of a pressurised medium operated installation 100 according to the invention with the pressure generating device, consisting of a pump 101, valves 102 and for example 103, as well as a pressure accumulator 104. The pump controls for example the pressure in the pressure accumulator 104 and in the regions upstream of the valves 102 and 103. The pressure can be controlled as desired by in the fluid connections downstream of the electronically controllable valves 102 and 103. To activate the clutch a hydraulic slave cylinder 110 is provided as the slave device which operates a clutch 121 by means of a slave cylinder piston ill. The clutch 121 is mounted in the drive train of a vehicle having a drive engine 122 and a gearbox 123.
To operate the gearbox 123 an operating unit 124 is provided which undertakes the shifting of the gears of the gearbox or in the event of a continuously variable transmission (CM undertakes the control or regulation of the contact pressure and/or the transmission ratio of the gears. To this end the pressure is adjusted in an hydraulic connection 125 by the electronically controlled valve unit 103. As connecting pipes 125, 126 between the slave devices 110, 124, pressurised medium fluid connections are formed as pressure pipes which have at least one part of their length designed as a corrugated tube 127, 128. The corrugated hoses 127, 128 are in one advantageous embodiment connected on at least one side to a pipeline 129, 130 which is connected to the pressure generating device and/or the slave device.
In a further embodiment of the invention the corrugated tube is connected on each side to a pipeline 129, 130, 131, 132 and these pipelines are connected respectively to 5 the pressure generating device and to the slave device.
In a further embodiment the entire pressurised medium fluid connection is formed in the area of the pressure line as a corrugated tube 11, 127, 128 and the corrugated tube regions are connected or attached directly to the pressure generating device and/or to the slave device.
Figure 3 shows a section of a connection according to the invention, such as a pressurised medium fluid connection which can be used in a high pressure area between a pressure generating device, such as for example a master cylinder, and a slave device, such as for example a slave cylinder. The pressurised medium fluid connection consists of one region as well as a partial area which is formed as a corrugated tube 200 and of partial areas 201 and 202 which consist of pipeline parts. In the area 203 and in the area 204 the corrugated tube 200 is connected to the pipelines 201 and 202. A clutch connection designed in this way thus consists of a tube with an interposed corrugated tube. In the event of manufacturing the pipeline and the metal bellows of steel it is now possible to use for example a welded connection as a simple compact and cost-effective connecting technique. Where applicable push-fit connections can also be used with interposed S-elastomer seals. Pressed or flanged connections are expedient in some embodiments.
It can be expedient if the corrugated tube or bellows of the corrugated tube is made of metal. In a further advantageous embodiment it can equally be expedient if the - 7 bellows are made of plastics.
It is expedient to use metal bellows or plastics bellows since these are advantageous for transporting fluid media.
Depending on the material these are pressure-resistant and therefore in a damage-free construction are vacuum tight and also fluid tight. More particularly the properties of the metal bellows remain practically constant over the temperature range and service life. When the material of the bellows is steel, for example stainless steel, the bellows can be made resistant to the fluid present inside so that corrosion properties and thermal influences become only slightly noticeable. Interactions between the metal of the metal bellows, and in part also the plastics of a plastics bellows, with the medium can thereby be avoided.
Connecting techniques between the corrugated tube and pipelines can be made cost-effective and compact, by way of example as welded connection/push-fit connection or other connections already mentioned. Fitting the pipeline for example inside a motor vehicle can be carried out easily since as a result of the flexibility of the corrugated hoses compensating tolerances through axial or lateral or angular adjustment is quick and easy.
The corrugated tube, for example made of metal, has as an elastic connecting element for example compensating functions between the engine and gearbox movement relative to the bodywork of the vehicle if for example the connecting pipe from the engine, gearbox or clutch of the vehicle is laid through an opening in the bodywork to an operating device, such as for example a pedal or operating actuator member. In this case as a rule the operating actuator member is mounted fixed on the bodywork and the clutch or gearbox operation is mounted fixed on the clutch 8 or gearbox or engine so that relative movements take place constantly between these two fastening points during operation of the motor vehicle.
In the case of using a corrugated tube of metal or a bellows of metal it can be advantageous if the surface is formed from metal and thereby a relatively stable element is employed against mechanical stresses. Corrugated tubes are also known by the term corrugated hose.
