GEARBOX & TRANSMISSION TEST SYSTEMS
From a single end-of-line gearbox test bench to a fully instrumented transmission test cell with input and output dynamometers — designed, manufactured and commissioned by one team.
These three words describe three different scopes, and the difference matters when you are writing a specification. The gearbox test dynamometer is the absorbing or driving machine. The gearbox test bench is that machine plus the mounting, coupling, instrumentation and control needed to run a unit under load. The gearbox test cell is the room and the services around the bench.
We quote and deliver at any of the three levels, and we tell you plainly which one your test list actually requires rather than selling the largest scope.
A transmission test bench for R&D looks nothing like an end-of-line one. R&D and durability rigs need wide operating envelopes, high channel counts and long unattended runs. An end-of-line transmission test cell needs cycle time, repeatability, a fixed test recipe and a pass/fail report the production line can act on.
We build both, plus the cases in between: quality audit benches, overhaul and revision test stands, NVH-oriented rigs, and back-to-back arrangements where power is recirculated rather than absorbed.
We have been doing only test systems since 1989, with close to 200 test facilities delivered and 20+ turnkey projects a year. The dynamometer, the control system and the software are ours — 97%+ local content, 100% Turkish capital — so one team answers for the whole gearbox test cell instead of three suppliers pointing at each other.
That also shortens the parts of a project that usually run late: integration, commissioning and the first weeks of production use.
In practice the terms are used interchangeably, and we build both under the same engineering. The meaningful distinction is the configuration: a single-input single-output gearbox test bench is a different machine from a transmission test cell with one driving and two absorbing dynamometers.
Yes, and it usually should. We design the fixturing, the shaft arrangement and the test recipes so that changeover between models is a planned operation rather than a rebuild. The realistic model range is decided during the configuration phase.
Yes. End-of-line benches are specified around cycle time, repeatability and reporting, with a fixed recipe and an unambiguous pass/fail output that integrates with production systems.
The same engineering applies — an e-axle is a gearbox with an electric machine attached. We build electric motor and electric drive test systems alongside conventional transmission test cells; see our test systems page for the full range.
