Automotive component test benches and In-Tyre-House Dynamo (ITHD) — wheel dynamometers of 94.2 and 160 kW
Country: Japan · Model: ITHD / DSD
Test benches for automotive components and the In-Tyre-House Dynamo (ITHD) wheel dynamometer of 94.2 or 160 kW. The bench reproduces the load on a transmission, engine or electric drive, while the ITHD is installed in the wheel arch in place of the wheel. Used in development and testing of manual, automatic and CVT transmissions, hybrids and electric vehicles.

Description
Component benches are built on low-inertia DSD dynamometers, a mechanical section and a control and measurement console. They reproduce the behavior of an internal combustion engine, and the configuration is chosen for the test object. Tests cover durability, performance, efficiency, noise and vibration, and subjective evaluation is also possible. The objects are front-drive and rear-drive units, transfer cases, differentials and engines. The console shows data on pointer and digital indicators and trends, and has two-stage alarms for each parameter. Control modes cover speed, torque, throttle position, adaptive speed, electric inertia with running resistance, servo lock, sinusoidal excitation, simulation of engine firing irregularity from the first to the fifth harmonic, resonance damping and shockless switching.
How to choose
For testing without major construction choose the ITHD, because a level floor is enough and it can be installed in anechoic and climatic chambers. The 94.2 kW version has a maximum speed of 2000 rpm, an instantaneous torque of 1350 N·m, a diameter of 650 mm, a width of 185 mm and brakes up to 425 mm in diameter. The 160 kW version is rated for 2500 rpm, 3800 N·m, 680 mm, 340 mm and brakes up to 460 mm. For heavier vehicles and larger brake discs choose 160 kW. A component bench is needed when the transmission or engine is tested separately from the body.

FAQ
How does the ITHD wheel dynamometer differ from a roller bench?
The ITHD is installed in the wheel arch in place of the wheel, needs no pit or slab and produces no tyre noise, with a noise level of about 70 dB. The four wheels are controlled independently.
What power versions of the ITHD are available?
94.2 and 160 kW. The first is rated for 2000 rpm and 1350 N·m, the second for 2500 rpm and 3800 N·m.
How is the ITHD mounted on the vehicle?
By jack through an adapter for any hub. Camber, caster and toe angles are preserved, and there are no wheelbase limits.
Which units can be tested on the bench?
Front-drive and rear-drive manual, automatic, CVT and hybrid transmissions, transfer cases, differentials and engines, as well as electric vehicles and hybrids.
Can autonomous driving systems be tested?
Yes, combined with cameras, radars and GPS, the ITHD dynamometer is used for safe bench testing of such systems.
