SAE no. 2 Model 1050 “Chase”

The Greening Model 1050Friction Material Test Machine is built to the specifications of SAE International’s J661 Brake Lining Quality Test Procedure, also known as the “Chase” test used for constant input friction force tests. Ideal for R&D work in friction materials including automotive brakes, clutches, truck brake blocks, and industrial friction materials.

The Model 1050 quickly and accurately measures effectiveness, fade, recovery, wear and speed sensitivity of brake and clutch friction materials. It generates automatic and real-time plots of friction and applied force, and test drum velocity and temperature. Heating and cooling curves are set automatically according to SAE J661 standards.

The model 1000/1250series dynamometers are designed for testing of braking systems for vehicle sizes ranging from motor bikes to commercial trucks. The dynamometers are equipped with a drive and a rotational inertia system to simulate deceleration and drag conditions, uphill or downhill grade effects, re-creation of hybrid or electric vehicle braking events, and other aspects of brake performance . These machines come with the latest control and data acquisition systems allowing the test engineer to quickly obtain accurate data on the performance of the brake assembly.

The advantage of this multispindle drilling machine for heavy duty brake blocks is the quick change over time. A complete preinstalled set of drill units, fixed on a carrier system, can be changed in a few minutes.

A zero clamping system guarantied the accurate locating of the drill units. Drill fixtures as well loading and unloading derives are quick changeable too. No settings are necessary. The machine is designed for in line. Different drilling programs can be stored and easily selected.

The output is about 600 pieces per hour. This machine can run 24 hours 7 days a week without downtime!

ERLMANN IRG-D is designed for the grinding of heavy duty drum break blocks after pressing and hardening process according to OEM-specification.

Grinding of up to 600 blocks per hour can be achieved.

The grinding wheel is mounted with 15 to 20 diamond coated grinding bodies, which are adjustable in high about 0,5 mm. These parts are easy to change. For each inside radius a corresponding basic grinding wheel is necessary. The grinding bodies are usable for the different basic units.

The machine is designed to accurately grind the outside radius of brake blocks to true radii according to OEM-specification and based on ROWLAND design. Brake blocks can be parallel or taper curved. The machine is run by one operator who stacks blocks in a magazine. Ground blocks exit to short rails.

Grinding of up to 900 blocks per hour can be achieved. This machine has been developed to meet the demands of Brake Block Manufacturers to produce parallel and taper curved brake blocks, even in small batches.

This CNC grinding machine is designed to replace standard machines that use expensive and inflexible tooling, reduce changeover time and offers many advantages over traditional machines, including:

Ability to grind taper and parallel blocks from a simple low cost cylindrical fixture drum made to the inside radius of the block.

The forementioned machine has been developed especially for drilling of drum brake linings for commercial vehicles. More than 200 machines have been built and sold to customers throughout the world.

The advantage of this machine is the big versatility. It works numeric controlled and covers nearly the total range of the worldwide existing drill patterns. That means, the machine allows drilling of linings or blocks

  • from 135 mm up to 250 mm inside radius
  • from 25 mm up to 260 mm width
  • with up to 12 holes per row
  • with up to 8 rows

The machine is programmed by a PLC SIEMENS S7. All functions can be dialled and handled on a touch panel, also the programming and saving of the row position and the pattern of the brake lining type which should be drilled.

EventScan CAR

EventScan CAR is used to acquire brake performance data and to identify and analyze brake noise and vibration effects. It has been especially developed for in-vehicle tests on the road.

Extensive trigger options, fast trigger reactions, as well as high dynamic and precise speed, deceleration, and stop distance measurements allow to use the system for brake performance tests, like ECE R13, ECE R90 type approval, FMVSS 135, FMVSS 105, On-Brake DTV, ABS operational tests, and any special stop distance test, even with high initial speeds up to 300 km/h.

Sound, vibration, and other fast varying signals are synchronously acquired with present operating conditions of the brake (like brake pressure, lining or disc temperature, brake speed, torque etc.). Signals are collected by analog inputs, CAN bus connections, GPS sensors, tachometer pulse inputs, net- work connections, and other devices. All acquisition and analyzing tasks are performed online and in real time.

The system is compatible with all common brake noise test standards and it meets the requirements of the current EKB and SAE recommendations dealing with brake noise tests.

EventScan systems have been applied by leading US, European, and Asian car manufacturers and it is globally used by brake system suppliers, friction and damping material manufacturers.
