Definitions
- the invention relates to a drive system of a pneumatically or hydraulically actuated shift cylinder of a transmission or a transmission-side power take-off.
- pneumatically or hydraulically operated switching elements use to control the operation of the transmission or the transmission-side power take-off or to regulate.
- At least one valve is associated with a shift cylinder, wherein the shift position of the shift cylinder can be influenced and thus adjusted by way of the or each valve.
- the actuation of the shift cylinder with a pneumatic or hydraulic pressure medium can be varied via the or each valve, so as to convert the shift cylinder in a desired shift position.
- the control of the or each valve associated with the shift valve is dependent on functional requirements of the shift cylinder with the aid of a control system, wherein in practice functional requirements of a shift cylinder can be processed only sequentially.
- the sequential processing of functional requirements can create functional gaps. Furthermore, overlaps between different functional requirements are not possible. As a result, the functionality of switching cylinders is limited.
- the present invention is based on the problem to provide a novel control system of a pneumatically or hydraulically actuated shift cylinder of a transmission or a transmission-side power takeoff, with which on the one hand function gaps avoided and on the other hand overlap of functional requirements are allowed.
- This problem is solved by a driving system according to claim 1.
- the drive system according to the invention comprises: a) first devices with which corresponding or simultaneously for several functional requirements of the shift cylinder corresponding valve requirements for the or each valve of the shift cylinder can be calculated; b) second means logically logically linking the valve requests calculated for the or each valve of the shift cylinder for each valve, said second means determining an effective drive for the respective valve from the valve requests calculated in parallel for the respective valve.
- the control system of a shift cylinder avoids the simultaneous or parallel processing of multiple functional requirements operating gaps in the control of the or each valve of the shift cylinder, furthermore overlaps of functional requirements in the control of the or each valve of a shift cylinder are allowed.
- Fig. 1 shows a preferred embodiment of a drive system according to the invention of a pneumatically or hydraulically operated shift cylinder with two chambers.
- the present invention is shown using the example of a drive system of a pneumatically actuated shift cylinder 1, wherein the shift cylinder 1 has two chambers 2 and 3 for a pneumatic pressure medium, namely for compressed air has.
- the switching cylinder 1 two valves 4 and 5 are assigned, namely such that each chamber 2 and 3 of the shift cylinder 1 is associated with a respective valve 4 and 5 respectively.
- About the valves 4, 5 can be fed either from a compressed air reservoir 6 to the chambers 2, 3 of the shift cylinder 1 compressed air or discharged from the chambers 2, 3 compressed air.
- Whether a chamber 2 or 3 of the shift cylinder 1 supplied compressed air or derived from the same compressed air is determined by the position of the corresponding valve 4, 5, wherein it is the valves 4, 5 in the illustrated embodiment to so-called 3/2 valves with three connections for compressed air and two valve positions.
- the corresponding chambers 2 and 3 of the shift cylinder 1 compressed air can be supplied, in a second position thereof, however, is derived from the chambers 2, 3 compressed air.
- valve position of the valves 4 and 5, which occupy the same for the pneumatic actuation of the shift cylinder 1 is determined by means of a drive system 7 according to the invention, wherein the drive system 7 of the invention, the control of the shift cylinder 1 associated valves 4 and 5 is used.
- the drive system 7 according to the invention provides an output signal 8 or 9 for each valve 4 or 5, wherein these output signals 8 and 9 of the drive system 7 according to the invention are a so-called effective control for the respective valve 4 or 5 in the sense of an effective electrical current supply is the same.
- the drive system 7 has first devices 10, 11 and 12 with the aid of which simultaneously or parallel for several functional requirements of the shift cylinder 1 corresponding valve requirements 13a, 14a, 15a for the valve 4 and corresponding valve requirements 13b, 14b and 15b for the valve 5 of Cylinder 1 are calculated. So z. B. with the first device 10 for the function request cylinder off for both valves 4 and 5 corresponding valve requirements 13a and 13b can be calculated. With the aid of the first device 11, corresponding valve requirements 14a and 14b can preferably be calculated for the function request for cylinder activation for both valves 4, 5. With the first device 12, however, corresponding valve requirements 15a and 15b can be calculated for the function request cylinder confirmation for the two valves 4 and 5. All valve requirements 13a, 14a, 15a, 13b, 14b and 15b for the valves 4 and 5 of the shift cylinder 1 are calculated by means of the first devices 10, 11 and 12 simultaneously or in parallel.
- control system 7 calculates, in addition to the valve requirements 13a, 14a, 15a, 13b, 14b and 15b dependent on the functional requirements cylinder deactivation, cylinder activation and cylinder confirmation, simultaneously or in parallel further valve requirements 16a and 16b, which in the exemplary embodiment shown in FIG. 1 are dependent on a feature request interrupt.
- the control system 7 comprises, in addition to the first devices 10, 11 and 12, by means of which the valve requirements for the valves 4 and 5 are calculated simultaneously or in parallel, further two devices 17 and 18, which for each valve 4 and 5 individually determine the effective control 8 or 9 for the respective valve 4 or 5 from the parallel calculated valve requirements.
- each valve 4 or 5 is assigned such a second device 17 or 18, wherein each of these second devices 17 and 18 respectively calculate the valve requirements 13a, 14a, 15a calculated for the respective valve 4 or 5 or 13b, 14b, 15b logically linked.
- the second devices 17 and 18 accordingly comprise logical operators, in the embodiment shown the logical operators 19, 20 and 21.
- the logical operators 19, 20 and 21 of the respective second devices 17 and 18 accordingly determine the respective effective control 8 or 8 by logically combining the valve request 13a, 14a, 15a or 13b, 14b, 15b calculated simultaneously for the respective valve 4 or 5 9 for the respective valve 4 or 5.
- the logical operators 19 are OR operators or OR operators, in the case of the logical operators 20 are NOT operators or NOT operators, in the logical Operators 21 to AND operators and AND operators.
- control system can therefore simultaneously and thus parallel processed multiple functional requirements of a switching cylinder and calculated for these functional requirements corresponding valve requirements. From the valve requirements calculated for each valve, an effective activation for the respective valve of the shift cylinder is determined by logic operation. This can be used to avoid functional gaps and to allow overlapping of functional requirements in the valve control.
- each chamber being associated with a 3/2 valve. It should be noted that the invention is not limited to this application, but rather can also be used in cylinders with two chambers, each of which two 2/2-valves are assigned. Likewise, the invention can be used in cylinders with a chamber, wherein the provision is made in a valve with a chamber via a spring element integrated into the cylinder. reference numeral
