An anti-lock braking system (ABS) is a safety anti-skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over the vehicle.
An automatic transmission is a multi-speed transmission used in motor vehicles that does not require any driver input to change forward gears under normal driving conditions. It typically includes a transmission, axle, and differential in one integrated assembly, thus technically becoming a transaxle.
Master/slave is a model of asymmetric communication or control where one device or process controls one or more other devices or processes and serves as their communication hub. In some systems, a master is selected from a group of eligible devices, with the other devices acting in the role of slaves.
Hydropneumatic suspension is a type of motor vehicle suspension system, designed by Paul Magès, invented by Citroën, and fitted to Citroën cars, as well as being used under licence by other car manufacturers, notably Rolls-Royce, Maserati and Peugeot. It was also used on Berliet trucks and has more recently been used on Mercedes-Benz cars, where it is known as Active Body Control. The Toyota Soarer UZZ32 "Limited" was fitted with a fully integrated four-wheel steering and a complex, computer-controlled hydraulic Toyota Active Control Suspension in 1991. Similar systems are also widely used on modern tanks and other large military vehicles. The suspension was referred to as oléopneumatique in early literature, pointing to oil and air as its main components.
A Formula One car is a single-seat, open-cockpit, open-wheel formula racing car with substantial front and rear wings, and an engine positioned behind the driver, intended to be used in competition at Formula One racing events. The regulations governing the cars are unique to the championship and specify that cars must be constructed by the racing teams themselves, though the design and manufacture can be outsourced.
The Aktiengesellschaft für Automobilbau was a German producer of cars in the 1920s in the German capital of Berlin.
A semi-automatic transmission is a multiple-speed transmission where part of its operation is automated, but the driver's input is still required to launch the vehicle from a standstill and to manually change gears. Most semi-automatic transmissions used in cars and motorcycles are based on conventional manual transmissions or sequential manual transmissions, but use an automatic clutch system. However, some semi-automatic transmissions have also been based on standard hydraulic automatic transmissions with torque converters and planetary gearsets.
ZF Sachs AG, also known as Fichtel & Sachs, was founded in Schweinfurt in 1895 and was a well-known German family business. At its last point as an independent company, the company name was Fichtel & Sachs AG.
In automotive engineering, the master cylinder is a control device that converts force into hydraulic pressure. This device controls slave cylinders located at the other end of the hydraulic brake system.
A preselector gearbox is a type of manual transmission mostly used on passenger cars and racing cars in the 1930s, in buses from 1940-1960 and in armoured vehicles from the 1930s to the 1970s. The defining characteristic of a preselector gearbox is that the gear shift lever allowed the driver to "pre-select" the next gear, usually with the transmission remaining in the current gear until the driver pressed the "gear change pedal" at the desired time.
Cherry GmbH is a German computer peripheral-device maker. The company has its roots in the United States and is headquartered in Germany. It has additional offices in the United States, France, and China. They manufactured a large range of products including sensors, vibrators and automotive modules until 1976, when Peter Cherry, the son of Walter L. Cherry, sold his company to ZF Friedrichshafen AG, a German supplier to the automotive industry. Cherry was renamed ZF Electronics GmbH, while the Cherry brand was continued only for its computer input devices. Since the beginning of 2016 this product line has been operating independently on the market as the Cherry Group. After an eight-year partnership with ZF Friedrichshafen AG, Cherry was sold to GENUI Partners in October 2016. In October 2020, Cherry was acquired by the private equity firm Argand Partners and as of June 2021 is now listed on the Frankfurt Stock Exchange as C3RY.
Automated manual transmission (AMT) denotes a type of motor vehicle transmission that is closely based on the mechanical design and build of a conventional manual transmission, but uses automatic actuation to operate the clutch and/or the gear shift mechanism.
A hydraulic brake is an arrangement of braking mechanism which uses brake fluid, typically containing glycol ethers or diethylene glycol, to transfer pressure from the controlling mechanism to the braking mechanism.
Apollo Automobil is a German sports car manufacturer headquartered in Denkendorf. Roland Gumpert, who founded Gumpert Sportwagenmanufaktur in 2004, once held the position of director of Audi Sport. Under his management, Audi won a total of 25 World Rally Championship rallies and four World Rally Championship titles.
The Killinger and Freund Motorcycle was an attempt in 1935 by a group of five German engineers from Munich to design a more streamlined and modified version of the German Megola front-wheel drive motorcycle. The work took three years to complete but the result was impressive. The engine displacement stayed the same as the Megola at 600 cc but was much lighter and more simplified than a standard 100 cc motorcycle of the time.
In road vehicles, the parking brake, also known as a handbrake or emergency brake (e-brake), is a mechanism used to keep the vehicle securely motionless when parked. Parking brakes often consist of a cable connected to two wheel brakes, which is then connected to a pulling mechanism. In most vehicles, the parking brake operates only on the rear wheels, which have reduced traction while braking. The mechanism may be a hand-operated lever, a straight pull handle located near the steering column or a foot-operated pedal located with the other pedals.
Deutsche Pentosin-Werke GmbH, commonly known as Pentosin, is a global independent manufacturer of lubricants and related speciality products. The company was founded in 1927 at Hamburg, Germany. The current Pentosin headquarters are at Wedel in Schleswig-Holstein, not far from where the company had been founded.
