ZF Lenksysteme

ZF Friedrichshafen AG, also known as ZF Group, originally ''Zahnradfabrik Friedrichshafen'', and commonly abbreviated to ZF (ZF = "Zahnradfabrik" = "Cogwheel Factory"), is a German car parts maker headquartered in Friedrichshafen, in the south-west German state of Baden-Württemberg. Specialising in engineering, it is primarily known for its design, research and development, and manufacturing activities in the automotive industry. It is a worldwide supplier of driveline and chassis technology for cars and commercial vehicles, along with specialist plant equipment such as construction equipment. It is also involved in rail, marine, defense and aviation industries, as well as general industrial applications. ZF has 241 production locations in 41 countries with approximately 148,000 (2019) employees.

ZF Friedrichshafen is more than 90% owned by the Zeppelin Foundation, which is largely controlled by the town of Friedrichshafen.

History

The company was founded in 1915 in Friedrichshafen, Germany by Luftschiffbau Zeppelin GmbH, to produce gears for Zeppelins and other airships. Zeppelin was unable to otherwise obtain gears for his airships. The German ''Zahnradfabrik'' (ZF) translates to 'gear factory' in English.

By 1919, ZF had moved into the automobile market, a move consolidated by the terms of the Treaty of Versailles. Some of the most important milestones that followed:

*1920: Patent application submitted for the Soden six speed transmission.
*1921: Under a rampant inflation and investor fears, the company went public as the ''Zepernicker Zahnradfabrik'', with the ''Zeppelin Luftschiffbau GmbH'' holding 80% of the stock options, valued at 4 million Marks.
*1927: Moved to Friedrichshafen and changed the name to ''ZF Friedrichshafen''
*1929: A thriving auto industry warrants the series production of the innovative helical ZF Aphon transmission for cars and commercial vehicles.
*1932: Launch of steering systems production under license. Today: ''ZF Lenksysteme GmbH''.
*1944: On 3 August, the ''Zahnradfabrik'' was bombed by the 304th BW / Fifteenth Air Force. As early as 20 September 1942, Albert Speer had warned Hitler of how important the Friedrichshafen tank engine production and the Schweinfurt ball-bearing facilities were. After the bombing, the company was relocated to former location, Zepernick until the 1970s.
*1944: Zahnradfabrik Friedrichshafen created the Panzer IV hydrostatischer, the only tank that they modified with their hydraulic drive.
*1953: Market launch of the first fully synchronised transmission for commercial vehicles worldwide.
*1961: Development of a fully automatic transmission for passenger cars. With series production beginning in 1969, and later proving highly popular, the 3HP20 is built to be swappable with the company's manual transmissions. The 1960s sees ZF supplying transmissions to major German automakers (including DKW, Mercedes-Benz, Porsche and BMW) as well as Peugeot and Alfa Romeo.
*1977: Start of volume production for automatic transmissions for commercial vehicles. Worldwide subsidiaries and factories were opened in the 1970s, and the company moved into India and South Korea.
*1980s: ZF started operating in Asia in the mid 80s
*1984: Majority shareholding gained in ''Lemförder Metallwaren AG'', today ''ZF Lemförder GmbH''.
*1986: Start of USA transmission production in Gainesville, Georgia, for pickup trucks. ZF became a major supplier to Ford in the 1980s.
*1991: The 5HP18 was the first 5-speed automatic transmission for passenger cars. Introduced in 1991 on the BMW E36 320i/325i and E34 5 Series
*1994: Development of an automatic transmission system for heavy commercial vehicles. The company expanded into China in the 1990s.
*1999: World premiere for the first automatic 6-speed transmission. Series production begins in 2001, with the BMW 7 Series as the first client. Today, ZF produces around one million six-speed automatic transmissions annually.
*2001: Acquisition of ''Mannesmann Sachs AG''. Today: '' ZF Sachs AG''.
*2001: Active Roll Stabilization(ARS) premiere on BMW 7 Series (E65)
*2002: Presentation of the world's first 4-point link – a newly developed chassis module for trucks and buses.
*2003: First deliveries of the Active Steering systems for passenger cars.
*2004: Ford starts volume production of the continuously variable transmissions (CVT) for passenger cars developed by ZF.
*2005: The 10-millionth airbag casing, the 5-millionth passenger car axle system and the 2-millionth 'Servolectric' electric power steering system are delivered.
*2006: ZF produces the 10-millionth passenger car automatic transmission.
*2007: One of the world's first 8-speed automatic transmissions, the 8HP boasted to achieve an 11% improvement in fuel economy in comparison with standard 6-speed automatic transmissions. Production began in 2009.
*2008: Acquisition of keyboard manufacturers Cherry Corporation. Incorporated into the ZF Electronics GmbH Corporate Division.
*2011: World premiere for the first automatic 9-speed transmission.
Land Rover demonstrated the world's first nine-speed automatic transmission for a passenger car at the 2013 Geneva Motor Show. The ZF 9HP transmission is designed for transverse applications, and is one of the most efficient and technically advanced transmissions ever used in a production vehicle. Land Rover is the lead partner with ZF on this project.

In the ''ZF Lenksysteme'' division (a 50:50 joint venture between ZF and Bosch), steering systems and components are produced, including steering columns, gears and pumps; Electric Power Steering (EPS); and Active Steering.

With the rise in popularity of the automatic transmission in buses, ZF introduced the ZF AS Tronic. The company also manufactures manual and automatic truck and bus transmissions. ZF transmissions are the ones used most commonly in buses. The Ecomat automatic transmission range which was introduced in 1980, is frequently used in buses.

''ZF Lemförder'' and ''ZF Sachs AG'' are all divisions/business units of ZF, specialising in original equipment and aftermarket solutions for the automotive industry.

ZF-TRW

ZF-TRW Automotive, headquartered in Livonia, Michigan USA operations primarily surrounding the design, manufacture and sale of safety systems. It operated approximately 200 facilities with 66,100 employees in 26 vehicle-producing countries.

ZF-TRW was acquired in 2015 and now is the 'Active & Passive Safety Technology' division.

Business development

In 1999, the steering systems division was made separate and became the new ZF Lenksysteme GmbH, an independent, 50:50 joint venture between ZF Friedrichshafen and Robert Bosch GmbH.

In 2007 ZF Friedrichshafen managed to increase its business volume about 8% to billion. The operating profit was about million. In 2008 ZF had a profit of million from a total business volume of billion. During the financial crisis ZF was one of the companies hit most. Its business volume decreased in turnover to billion. Total loss was about million. According to the current development ZF is forecasting sales growth of about 10%, which would be above the industry average.

Due to the financial crisis ZF received a credit of about million by KfW. At the end of the term, it has to be paid back with interest. Being a state bank, the KfW aid is not considered governmental support. ZF is about to save million without reducing its permanent staff. Contracts of short-term employees were not extended. Total number of employees was reduced from 63,000 to 59,000 worldwide. According to CEO Härter, there is no need for further employee reduction.

On 16 September 2014, the Wall Street Journal reported that ZF agreed to acquire TRW Automotive Holdings for $13.5 billion. The acquisition would create the world's second largest automotive parts concern, ranked just behind Robert Bosch GmbH.
For clearing way to acquire TRW Automotive Holdings, ZF Friedrichshafen AG sold its stake in ZF Lenksysteme GmbH to Robert Bosch GmbH. ZF Lenksysteme GmbH has now been renamed as Robert Bosch Automotive Steering GmbH.

In September 2020, ZF Friedrichshafen AG entered a partnership with Aeva Inc to put Lidar sensors, a sensor for self-driving vehicles, into production.
