'HEF109-L starter'에 해당되는 글 1

  1. 2014.08.22 The new Bosch HEF109-L starter motor for commercial vehicles

Large-volume engines place great demands on starters. At the top end of the power range, Bosch has a new addition to its 24-volt starter motor portfolio: the HEF109-L “large” heavy-duty starter motor for commercial vehicles and off-highway applications. The powerful starter motor generates 18 percent more power than the tried and tested “M” (medium) type starter motor on which it is based, and thus delivers a maximum output of 9.2 kilowatts. This is enough to reliably start engines with up to 28 liters displacement. Ulrich Kirschner, the president of Bosch’s Starter Motors and Generators division, sums up the benefits as follows: “This new high-performance starter motor is an excellent choice for particularly large engines such as construction machinery. These engines were previously very difficult to start with single starter-motor configurations.” This powerful single-starter solution makes a more complex parallel-starter system unnecessary. The technology is designed to achieve a mileage of up to 800,000 kilometers in on-highway use or 14,000 operating hours in off-highway applications.




Compact, robust, and reliable

The design of the HEF109-L with its 6-pole excitation concept is especially compact, making it particularly suitable for applications where installation space in the engine compartment is limited. The high thermal robustness ensures reliable starting of large engines – even at very low ambient temperatures or in long-lasting starting sequences.


Due to the significantly greater service-life requirements associated with commercial vehicles, the engagement itself is designed as a two-stage process in order to limit the wear of the ring gear and pinion: In the first stage, the pinion shaft including the pinion is moved forward cautiously, engaged, and turned slightly. In the second stage, the main current is released and the actual starting sequence takes place.


A mechanical relay integrated in the starter makes a connection to the engine control unit (ECU) easier. Unlike starts by ignition switch, the ECU can automatically control the starting sequence, which keeps emissions low.


For extreme conditions

The HEF109-L can also be upgraded. One example is the special dust protection, available up to IP57 protection class. An additional feature is the isolation of terminal 31. This separate connection to the battery’s minus pole is a feature of special applications such as railroad vehicles or watercraft, where increased safety and protection requirements against moisture and water apply. For maximum flexibility in diverse installation conditions, the starter motor can also be supplied with all common flange geometries, including a rotatable flange.


Parallel starter-motor systems with increased power output

For applications utilizing even larger-displacement engines, Bosch offers parallel starting systems. By setting two or three starter motors of the 109-family in a parallel-system configuration, the output of each individual starter motor can be aggregated. The new HEF109-L also allows the total output of the parallel starter-motor systems to be increased significantly. With a maximum output of almost 28 kilowatts, diesel engines with displacements of up to 84 liters and gas powered engines with displacements of up to 168 liters can be started reliably under normal conditions. Engines of this size are very common in off-highway applications and watercraft. Stationary engines such as generator sets – also need to start quickly and reliably to stabilize the power supply net if there is a power cut. The HEF109-L is an ideal choice for these applications as well.


Automotive Technology is the largest Bosch Group business sector. In 2013, its sales came to 30.6 billion euros, or 66 percent of total group sales. This makes the Bosch Group one of the leading automotive suppliers (NB: Due to a change in accounting policies, the 2013 figures can only be compared to a limited extent with the 2012 figures). Automotive Technology largely operates in the following areas: injection technology for internal-combustion engines, alternative powertrain concepts, efficient and networked powertrain peripherals, systems for active and passive driving safety, assistance and comfort functions, technology for user-friendly infotainment as well as car-to-car and Car2X communication, and concepts, technology, and service for the automotive aftermarket. Bosch has been responsible for important automotive innovations, such as electronic engine management, the ESP anti-skid system, and common-rail diesel technology. 

The Bosch Group is a leading global supplier of technology and services. In 2013, its roughly 281,000 associates generated sales of 46.1 billion euros. (NB: Due to a change in accounting policies, the 2013 figures can only be compared to a limited extent with the 2012 figures). Its operations are divided into four business sectors: Automotive Technology, Industrial Technology, Consumer Goods, and Energy and Building Technology. The Bosch Group comprises Robert Bosch GmbH and its roughly 360 subsidiaries and regional companies in some 50 countries. If its sales and service partners are included, then Bosch is represented in roughly 150 countries. This worldwide development, manufacturing, and sales network is the foundation for further growth. In 2013, the Bosch Group invested some 4.5 billion euros in research and development and applied for some 5,000 patents. This is an average of 20 patents per day. The Bosch Group’s products and services are designed to fascinate, and to improve the quality of life by providing solutions which are both innovative and beneficial. In this way, the company offers technology worldwide that is “Invented for life.”
