Mayr Power Transmission:
Brake Technology 4.0
Brake technology 4.0 by Mayr Power Transmission
stands for monitoring modules of the latest generation:
The modules such
as the ROBAbrake-checker
or
ROBA-torqcontrol allow
permanent brake
monitoring and make
the safety brakes fit for
the challenges of the
Industry 4.0. Firmly
connected with the
brake technology 4.0
concept are also a
technologically leading
friction system and
consistently-observed
safety principles. Together, these characteristics form
the basis for reliable and safe brakes with extremely
high performance density. They guarantee highest
operational safety in more and more compact and
high-performance machines and systems, and allow
targeted, predictive maintenance.

Eaton’s hydraulic hoses designed for tighter
spaces, higher temperatures and abrasion
Power management company Eaton has expanded its range of hydraulic
hoses with the launch of the Dynamax EC881 hose series. The new
EC881 series from Eaton is qualified for 1 million impulse cycles, five
times more than the standard EN857 Type 2SC. This helps decrease
maintenance costs, improves safety and minimizes downtime. Standard
EN857 2SC size 8 hoses are only qualified to 130 mm radius, whilst
EC881 offers a bend radius of 60 mm. This makes the new hose the ideal
choice for installation in tight spaces. Featuring Dura – Tuff covers, the
EC881 is 8 times more resistant to abrasion than conventional synthetic
covered hoses, ultimately leading to less failures and improved machine
up time. In extreme operating environments high velocity leads to high
temperatures. The EC881 has been designed to offer temperature
capabilities up to 126 °C, thus mitigating against the risk and ultimately
controlling maintenance costs. Eaton engineers have focused on
developing a next generation inner tube that has 3 times the life span
capabilities when compared to the standard EN857 2SC. EC881’s high
fatigue resistance and low compression set provides better sealing and
leak free performance.

Rotational speed and directional sensor
with PWM-signal from Rheintacho
With a new rotational speed sensor from the FE series, Rheintacho
presents a sensor ideally suitable for hydraulic drives used
in construction and agricultural equipment. From the beginning
of the design concept, the design took highly demanding working
conditions into consideration. Having this in mind, the sensor
achieved the IP67 and IP6K9K ratings. This means dirt, moisture
and intensive cleaning methods are no problem for the sensor.
The housing is made of a special brass alloy which ensures that
the compressive strength of the measuring surface is high. The
new sensor adds a rotational direction signal to the rotational
speed signal. The electronic design with a pulse-width modulated
signal (PWM) works with a current
signal differing from the 1-channel
and 2-channel version, on which the
rotational direction information is
transmitted through the differing
pulse lengths. At the same time, this
sensor also provides a signal with a
constant amplitude independent
from the rotational speed. It excels
not only by detecting rotational
speed and direction, but also
provides additional diagnostic
functions, e.g. downtime recognition,
critical air gap and critical
installation position.

Control units of the fourth
generation from STW
Sensor-Technik Wiedemann (STW) showcases its fourth
generation of controls for mobile applications. The
ESX-4CS-GW is a freely programmable a communications
gateway, it not only offers 6 CAN interfaces, but also a
4-port Ethernet switch, a LIN and a RS232 interface. With an
additional 14 analog and digital inputs and outputs in the
standard configuration, it is also able to take over small
tasks for sensor-actuator
management. For fast
processing of the tasks, the
fourth generation of the ESX
control units feature the
Infineon Aurix processor,
which works with 300 MHz
using three 32-bit TriCore
processor as the so-called
“Triple-TriCore”, each of
which are independent from the other. Naturally the
ESX-4CS-GW complies with the standards for conformity
according to CE and E1 as well as the standards for the
vehicle, agricultural and construction machine industry.
The respective development environments for the fourth
generation of control units are ‘codesys’ and openSYDE.
With openSYDE, STW displays its framework and toolset for
the implementation, analysis, maintenance and documentation
of functions and programs in the control system for
mobile machines.
