Jakob Buchli
Jakob Buchli (4 March 1876 – 1 April 1945) was a Swiss design engineer in the field of locomotive construction. Life Jakob Buchli was born in Chur, Switzerland, on 4 March 1876. After his training to be an engineer he worked from 1902 to 1910 for the Swiss Locomotive and Machine Works (''Schweizerische Lokomotiv- und Maschinenfabrik'' or ''SLM'') in Winterthur; from 1907 as its head of the design office. After that he switched to Brown, Boveri & Cie. in Baden, Switzerland, where he was the chief engineer for electric traction until 1924. From 1924 to 1930 he was technical director of the locomotive construction department of the SLM. Amongst his most important designs were the Buchli drive (1918) named after him and used on the SBB Class Ae 4/7 amongst others, the Java bogie, the Winterthur Universal Drive and the duplex bogie for express coaches. He died in Winterthur on 1 April 1945. See also * List of railway pioneers A railway pioneer is someone who has made a sig ...

Java Bogie
The Java bogie (german: Java-Drehgestell, Java-Gestell often in Swiss literature), was a bogie for electric locomotives manufactured by the Swiss Locomotive and Machine Works (SLM). It contained a driving wheel and a trailing wheel. It got its name because it was first installed in the 3000 series express train locomotives delivered to the ''Electrische Staats Spoorwegen'' (ESS) on Java in 1925. Technology The planned increase in the maximum speeds on the electrified main lines in Switzerland beyond 100 km/h prompted the SLM designer Jakob Buchli to improve the cornering of the electric locomotives. The Krauss-Helmholtz bogie with its relatively light superstructure was not enough on the winding Swiss routes. As a result of his investigations, the bogie, later called the Java bogie, was created. Its vertical axis of rotation was close to its driven axis, so that the conditions for ''radial adjustment'' in curves were optimal for it: the ''approach angle of'' the wheels a ...

Express Coach
A bus (contracted from omnibus, with variants multibus, motorbus, autobus, etc.) is a road vehicle that carries significantly more passengers than an average car or van. It is most commonly used in public transport, but is also in use for charter purposes, or through private ownership. Although the average bus carries between 30 and 100 passengers, some buses have a capacity of up to 300 passengers. The most common type is the single-deck rigid bus, with double-decker and articulated buses carrying larger loads, and midibuses and minibuses carrying smaller loads. Coaches are used for longer-distance services. Many types of buses, such as city transit buses and inter-city coaches, charge a fare. Other types, such as elementary or secondary school buses or shuttle buses within a post-secondary education campus, are free. In many jurisdictions, bus drivers require a special large vehicle licence above and beyond a regular driving licence. Buses may be used for scheduled bus t ...

SBB-CFF-FFS Ae 4/7
The Ae 4/7 was a universal locomotive of the Swiss Federal Railways, employing the so-called Buchli drive. Thanks to this drive construction, invented by Jakob Buchli, it was one of the longest-lasting locomotives. It was in regular use for 7 decades, from the 1920s into the 1990s, hauling freight and passenger trains all over Switzerland. History In the 1920s stronger locomotives were needed for the Swiss plateau (which has grades up to 12‰). The existing locomotives with three driven axles were a bit weak for their services. Because the Buchli drive already proved to be reliable on the , two prototypes of the Ae 4/7 were ordered in 1925. Subsequently, in total 127 were built between 1927 and 1934. While the mechanical part was built by the Swiss Locomotive and Machine Works, the electrical equipment was built in three varieties, because these parts were built by three different manufacturers, Brown, Boveri & Cie.

Design Engineer
A design engineer is an engineer focused on the engineering design process in any of the various engineering disciplines (including civil, mechanical, electrical, chemical, textiles, aerospace, nuclear, manufacturing, systems, and structural /building/architectural) and design disciplines like Human-Computer Interaction. Design engineers tend to work on products and systems that involve adapting and using complex scientific and mathematical techniques. The emphasis tends to be on utilizing engineering physics and other applied sciences to develop solutions for society. A design engineer usually works with a team of other engineers and other types of designers (e.g. industrial designers), to develop conceptual and detailed designs that ensure a product functions, performs, and is fit for its purpose. They may also work with marketers to develop the product concept and specifications to meet customer needs, and may direct the design effort. In many engineering areas, a distinction ...

Buchli Drive
The Buchli drive is a transmission system used in electric locomotives. It was named after its inventor, Swiss engineer Jakob Buchli. The drive is a fully spring-loaded drive, in which each floating axle has an individual motor, that is placed in the spring mounted locomotive frame. The weight of the driving motors is completely disconnected from the driving wheels, which are exposed to movement of the rails. First used in electric locomotives from the 1920s, the Buchli drive made possible the construction of faster and more powerful locomotives that required larger and heavier traction motors. The system minimises the impact on rail tracks due to the reduction in the overall unsprung weight. Although the drive was very successful though the 1930s, it is little used in modern locomotives, having been replaced with smaller, simpler drives that exhibit less imbalance and allow higher speeds. Construction In a Buchli drive a driven gear wheel is securely fixed to the locomotive f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
