Problems solved by technology

[0006] Thus, in the case of all said tests, it is generally the case that at least two units, in particular an output unit and a drive unit, are required outside the transmission for testing, said units being extremely bulky and thus are required in transmission test and measuring equipment for this purpose and are also required, of course, for dual clutch transmissions, which in particular involve considerable investment costs

no. 1 example

[0079] Transmission preload method for measuring and testing a transmission, in particular a dual-clutch transmission 1 with at least two component transmissions, in which method by means of a drive unit external to the transmission 1 and defined with respect to traction operation 2 Introducing torque into the transmission 1, the method is characterized in that the transmission 1 is brought into an operating state in which the introduced torque is absorbed by means of at least one part of the transmission 1 in a manner This is done so that the measurement and / or test can be carried out without an output unit 3 external to the transmission 1 and defined with respect to traction operation.

no. 2 example

[0081] The method according to the first embodiment, wherein, in the NVH test, output drive with slip in at least one member clutch 4,5 of the transmission 1 through at least one member of the member transmission 6,7 resulting from the slipping partial engagement of the clutches 4, 5, where the gears G1-G7, GR are engaged in each of the member transmissions 6, 7, where a) one member clutch 4 of the first member transmission 6 is partially engaged so that slip is exhibited and one member clutch 5 of the second group member transmission 7 is partially to fully engaged without slip and the member clutches 4, 5 are not disengaged, or b) one of the second group member transmission 7 The crew clutch 5 is partially engaged so as to exhibit slip, and one crew clutch 4 of the first crew transmission 6 is partially to fully engaged without slip, and the crew clutches 4, 5 are not disengaged.

no. 3 example

[0083] A method according to the second embodiment, wherein a) variant a) of the second embodiment is performed first, and then variant b) of the second embodiment is performed, or b) variant b) of the second embodiment is performed first , and then variant a) of the second embodiment is executed.

Abstract

The invention relates to a method for testing a transmission, in particular a dual clutch transmission. Torque is introduced into the variator by means of a drive unit external to the variator, and the variator is switched into an operating state in which an internal component of the variator acts as a brake to simulate an output unit.

Description

technical field [0001] The invention relates to a transmission preloading method for measuring and testing a transmission having at least two component transmissions, in particular a dual clutch transmission, in which method, by means of a transmission external to the transmission and The introduction of a torque by a drive unit, in particular a dual clutch transmission, is defined relative to the traction operation. Background technique [0002] "Traction operation" means an operation corresponding to a traction operation of a vehicle in which a drive unit, in particular in the form of an engine, introduces torque into a dual clutch transmission via a plurality of clutches, wherein said torque is then transmitted via An output unit is ultimately output, for example and in particular via some wheels fixed to the vehicle and the axles of said wheels. [0003] Thus, during non-traction operations, in particular in the parked state, the output unit, in particular the wheels wi...
