TIRE TEST RIGS
CFM Schiller offers extensive experience in design and manufacturing of customized tire test rigs. The following examples show some of our produced test rigs for tire development in the fields of endurance testing, acoustics, and force measurements.
We gladly consult and accompany you during layout, design, and commissioning of your very own tire test rig – feel free to contact us.
Endurance Test Rig
Endurance Test Rig
CFM Schiller has recently developed and delivered a test rig for endurance testing of commercial vehicle tires. In this test rig, a maximum force of 250 kN is applied to tires with a diameter between 1 000 and 2 500 mm (39.4”-98.4”) and a width of up to 1 000 mm. The velocity is continuously adjustable to a maximum value of 160 km/h (100 mph). This test rig allows the simultaneous examination of two tires with different sizes and different applied forces at the same velocity.
ACOUSTIC TEST RIGS
Tire Test Rig with Application of Preload
This CFM Schiller tire test rig with manual application of preload is intended for testing of tire noises in a laboratory environment. Tire diameters from 13” to 22” can be tested.
The tire test rig can be manually moved with a pallet jack allowing a flexible placement of the test rig. The wheel adapter, which is equipped with preloaded tapered roller bearings, can be manually adjusted in height with a crank handle. The springs are designed in such a way that they are similar to the stiffness of a vehicle suspension. They enable testing with forces between approx. 3 000 N and 7 000 N. The springs can be disabled for testing without spring stiffness. Toe and camber properties are both manually adjustable.
Wheel / Tire Test Rig
For determination of forces to the wheel and examination of tire noise during operation
To determine structure-borne and airborne sounds on wheel and tire systems under different operating conditions, adjustable test rigs are necessary. This test rig offers manual adjustability of toe and slip angle.
The natural frequency of the structure is >300 Hz in order to achieve correct measurement results. Integrated air springs and a pinned support allow elastic support of the wheel adapter. The air springs are furthermore used to continuously adjust the tire loading. For testing under fixed conditions, the test rig components are clamped by means of screws. The load cell, measuring instruments, and the specimen are attached to the test rig with customized adapters.
