Busscar trolleybus in São Paulo, Brazil Solaris trolleybus in Landskrona, Sweden Video of a trolleybus in Ghent, Belgium. A trolleybus (also known as trolley bus, trolley coach, trackless trolley, trackless tram – in the 1910s and 1920s [1] – or trolley [2] [3]) is an electric bus that draws power from dual overhead wires (generally suspended from roadside posts) using spring-loaded ...
Trolley pole on a Toronto streetcar, tipped with a trolley shoe. A trolley pole is a tapered cylindrical pole of wood or metal, used to transfer electricity from a "live" (electrified) overhead wire to the control and the electric traction motors of a tram or trolley bus.
The Electromote built by the Siemens & Halske company was a converted four-wheel landau carriage, equipped with two 2.2 kW electric motors, each of which transmitting power directly to one of the rear wheels using a chain drive. This was because a working differential was not available at the time. The voltage used was 550 V DC.
Three types of electric road systems. An electric bus (black) receives power from the road: (A) with three inductive pickups (red) from a strip of resonant inductive coils (blue) embedded several centimeters under the road (gray); (B) with a current collector (red) sliding over a ground-level power supply rail segment (blue) flush with the surface of the road (gray); (C) with an overhead ...
Horse-drawn buses were used from the 1820s, followed by steam buses in the 1830s, and electric trolleybuses in 1882. The first internal combustion engine buses, or motor buses, were used in 1895. Recently, interest has been growing in hybrid electric buses , fuel cell buses , and electric buses , as well as buses powered by compressed natural ...
A battery electric bus is an electric bus that is driven by an electric motor and obtains energy from on-board batteries. Many trolleybuses use batteries as an auxiliary or emergency power source. Battery electric buses offer the potential for zero-emissions, in addition to much quieter operation and better acceleration compared to traditional ...
In Britain, Leeds introduced Europe's first overhead electric service (Roundhay Electric Tramway) on 29 October 1891, though strictly speaking, it did not officially open to passengers until the following month. [30] The Volk's Electric Railway was opened in 1883 in Brighton. This two kilometer line, re-gauged to 2 feet 9 inches (840 mm) in ...
Traction motors are used in electrically powered railway vehicles (electric multiple units) and other electric vehicles including electric milk floats, trolleybuses, elevators, roller coasters, and conveyor systems, as well as vehicles with electrical transmission systems (diesel–electric locomotives, electric hybrid vehicles), and battery ...
