Kyntronics

Delivers Smart Actuation with Compact, Energy-Efficient System

The actuation market is projected to grow from an estimated $38 billion in 2017 to $49 billion by 2022. Given this growth trajectory, the focus is moving away from traditional actuation options that have a myriad of cumbersome deficiencies to more streamlined innovative solutions that provide higher efficiency (lower costs), increased uptime, and integrated-simple connectivity.

The goal is to take advantage of enhanced technologies that can achieve higher efficiencies via factors such as less maintenance, advanced connectivity (field buses), lower weight, compact footprint, accuracy, and energy efficiency.

In response to the customer demand for these actuation efficiency goals, Kyntronics (Cleveland, Ohio), has developed its patent-pending SMART Hydraulic Actuator (SHA) –a development in ‘power-on-demand’, servo-controlled, variable speed actuation. Made in the USA, this new actuation technology achieves the optimal technological compromise–combining the best advantages of hydraulics and electromechanical servo technology minus their disadvantages engineered in an all-in-one, scalable, modular assembly.

New to the OEM market, the Kyntronics’ SHA offers an all-in-one (variable-speed motor, drive, and cylinder) actuation system that precisely controls position, force, and speed in applications requiring from 500 lb. (2,225N) to over 100,000 lb. (445 kN) of force capacity. High force and quick cycle times in a compact package, the all-inclusive system produces strokes up to 120 in. (3,048 mm).

Traditional actuation systems over the past several decades focused on three primary types: electromechanical, hydraulic, and pneumatic. With the advent of Kyntronics SHA, SMART electro-hydraulic actuators now represent a fourth category that leads the growth trajectory of next-generation actuation. Whereas traditional actuation systems all have their distinct advantages, each have inherent core disadvantages — examples include the reliability of electromechanical systems, inefficiency of hydraulic actuators, and the maintenance required with pneumatics.

Kyntronics SHA all-in-one system combines the key benefits of an electronic servo system with the power density of hydraulics. The flexible system can be oriented in any position and features a compact footprint–combining the power to weight ratio advantage of hydraulic technology with the versatility, ease of installation, and control of electric servo technology.

It is powered by a servo motor that drives a hydraulic pump which generates pressure to act on a cylinder to provide optimal mechanical actuation force. The configuration also features a servo drive controller, actuator, manifold, and built-in transducers–providing essential closed-loop precision force and position control. Fieldbus capabilities include Ethernet, CAN, & Serial.

A notable key benefit of the system is the way the differential volume is accounted for between a cylinder’s cap and rod ends. To compensate for this differential, the hydraulic cylinder includes an outer low-pressure cylinder with a second inner high-pressure cylinder–creating a chamber between the two. Ultimately, the product delivers high force density in a small footprint with precision, while offering “power-on-demand’ energy efficiency–only running when needed.

“The key inspiration for our research and development on the SHA product came from vital input from our customers who wanted to embrace the global trends of increasing automation, higher precision requirements, lower costs, and more connectivity,” said Wayne Foley, president at Kyntronics.

“Electro-hydraulic technology has been driving actuation market growth, and we strive to provide our customers and channel partners with unique solutions like the SHA that are ahead of the curve. Our nimble, responsive team of in-house engineers thrive on ‘solving the unsolvable’ actuation application problem and are equipped to provide the best combination of mechanics, electronics, software, and support solutions in actuation today,” added Carl Richter, vice president and general manager.

Dana

Collaborates with Mecalac on E-Drivetrain

Dana Incorporated has announced that the company has been collaborating with Mecalac to develop a customized e-Drivetrain system for the new Mecalac e12 electric compact wheeled excavator. This vehicle earned the Energy Transition Award earlier this year as part of the 2018 Intermat Innovation Awards.

With the proven Mecalac 12MTX as a base frame, this version is the world’s first compact wheeled excavator powered entirely by electricity. Featuring Spicer 112 axles and a Spicer 367 shift-on-fly transmission, the Mecalac e12 wheeled excavator delivers the range, performance, and compact size required to support modern urban construction sites.

“As the European construction market embraces the trend toward zero-emission standards for small to mid-sized vehicles, our customers are demanding great strides in efficiency while also requiring reliable performance,” said Jean-Baptiste Rousseau, technologies manager at Mecalac. “Dana was able to adapt the 12MTX drivetrain to add electric drive capabilities within our existing vehicle architecture. With their technical expertise and open collaboration, we developed an optimal solution and accelerated the delivery of this vehicle to market.”

With an eight-hour working range, the engine compartment in the Mecalac e12 houses LiFePO4 battery technology — lithium iron phosphate for service life that is three times longer than classic batteries. The batteries can be charged in approximately seven hours.

Dana has a long history of developing drivetrain systems for hybrid and electric vehicle architectures. The company also offers patented battery and electronic cooling technologies, along with fuel-cell technology. In addition, Dana engineers had extensive experience with this particular application because the diesel-powered version of this vehicle also features Spicer drivetrain components.

“As a Tier-One supplier, we understand that the success of electrification in the off-highway industry is driven by performance. These technologies must support a smooth transition to fully integrated electric-drive technologies optimized within a single package, providing both electrified and conventional powertrain options,” said Aziz Aghili, president of Dana Off-Highway Drive and Motion Technologies. “Dana’s support for new energy vehicles has been considerable, and growing every year, as the importance of engineering for hybridization and electrification is further elevated throughout the industry.”

Klüber Lubrication

Designs Lubricating Grease for Modern Electric Brake Applications

Klüber Lubrication, a worldwide manufacturer of specialty lubricants, has developed Klübersynth GR 46-52 F, a fully synthetic special lubricating grease for actuators in motor vehicles.

In today’s vehicles, brake actuators, both for full service brakes and electric park brakes, have become popular as electric assistants, replacing the formerly used hydraulic circuit. EPDM materials continue to be used, which makes compatible lubricants a necessity.

In this context, Klübersynth GR 46-52 F has a specially tailored chemistry to promote compatibility with EPDM. At the same time, it helps save significant costs as an efficient alternative to the frequently used PFPE- or silicone-oil-based lubricants.

Klübersynth GR 46-52 F is a solid lubricant that ensures reliable separation of surfaces, enabling constant start up torques over a long lubricant life. The lubricant helps extend component life with a high proportion of sliding friction as well as with rolling motion. This in turn aids in making the driving experience even safer and more comfortable.

Klübersynth GR 46-52 F was specifically developed for electric brake actuators, mostly small actuators, in motor vehicles. The individual actuation method may consist of spur gears, worm gears, spindle mechanisms, and ball screws. The lubricant is ideal where compatibility with EPDM and/or brake fluid is required in polymer/steel material combinations.

Joral

Offers Sensor Fusion Inclinometer for Pitch, Yaw and Roll Feedback

Joral LLC announces a G-force compensated inclinometer that provides feedback for pitch, yaw, and roll. The new technology utilizes sensor fusion, which is the combining of more than one complementary sensing method. The new Joral SGAM and DGAM incline sensors take input by a gyroscope, accelerometer, and magnetometer to provide a 3-axis output for X, Y, and Z as well as new feedback for pitch, yaw, and roll.

The GAM Series sensor provides steady feedback during motion, allowing users to eliminate complex sensor networks with a single G-force compensated inclinometer. Rather than depending on encoders, string pots, laser gates, and proximity sensors to monitor the position of a ladder, fork or platform, users can place one Joral GAM Series sensor on the application to get real-time feedback for absolute control.

Joral has designed the same level strength into the GAM series as other standard Joral products. Rated with a standard environmental protection of IP67, the GAM series sensors are 100% encapsulated. Designed to eliminate the drawback of accelerometer based incline sensors, the SGAM and DGAM inclinometers are J1939 capable, and available in a convenient form factor with common connection options.
