Shift Time
Shift time refers to the time interval between gear changes in a transmission. This interval is the time in which power delivery is transferred to the next selected gear, and engine speed is reduced or increased to synchronize the speed of the next gear. Shift time is usually in reference to motor vehicles, but can apply to any gearbox. Reducing shift time is important in performance and racing vehicles because upshifting generally interrupts power delivery to the wheels. Shift time in a manual gearbox is dependent on the driver, but in automatic or automated manual cars, the electronic or hydraulic control system must be calibrated and tuned to execute fast gear changes. Generally, a dual-clutch transmission shifts faster than a standard hydraulic automatic transmission with a torque converter or a single-clutch automated manual transmission. This is possible because the DCT can pre-select the next gear and switch between its two separate clutches to the next pre-determined g ...

Gear
A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called ''cogs''), which mesh with another (compatible) toothed part to transmit (convert) torque and speed. The basic principle behind the operation of gears is analogous to the basic principle of levers. A gear may also be known informally as a cog. Geared devices can change the speed, torque, and direction of a power source. Gears of different sizes produce a change in torque, creating a mechanical advantage, through their ''gear ratio'', and thus may be considered a simple machine. The rotational speeds, and the torques, of two meshing gears differ in proportion to their diameters. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a '' transmission''. The gears in a transmission are analogous to the wheels in a crossed, belt pulley system. An advantage of gears is tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flywheel
A flywheel is a mechanical device which uses the conservation of angular momentum to store rotational energy; a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed. In particular, assuming the flywheel's moment of inertia is constant (i.e., a flywheel with fixed mass and second moment of area revolving about some fixed axis) then the stored (rotational) energy is directly associated with the square of its rotational speed. Since a flywheel serves to store mechanical energy for later use, it is natural to consider it as a kinetic energy analogue of an electrical inductor. Once suitably abstracted, this shared principle of energy storage is described in the generalized concept of an accumulator. As with other types of accumulators, a flywheel inherently smooths sufficiently small deviations in the power output of a system, thereby effectively playing the role of a low-pass filter with respect to the mechanical velocity ...

Ferrari FXX
The Ferrari FXX is a high-performance track-only developmental prototype built by Italian automobile manufacturer Ferrari. The FXX is based on the street-legal flagship Enzo Ferrari. Production of the FXX began in 2005. Overview The FXX uses some technology demonstrated on the Enzo Ferrari and combines it with new developments from Ferrari and its suppliers. However, the car is only a part of the overall FXX program. Customers pay GB£2 million, but are only allowed to drive the car on special track days which are approved by Ferrari. After they drive the car, the owners are entitled to be debriefed by Ferrari on the car's performance. Ferrari's sister company Maserati, has developed a similar car, the MC12 Versione Corsa for this purpose with the only difference being that the owners can keep the car in their custody. Lamborghini also allows their track-day car, the Essenza SCV12, to be kept by the custody of their customers. The FXX may be stored by owners wherever they ple ...

Ferrari F430
The Ferrari F430 (Type F131) is a sports car produced by the Italian automobile manufacturer Ferrari from 2004 until 2009 as a successor to the Ferrari 360. The car is an update to the 360 with exterior and performance changes. It was unveiled at the 2004 Paris Motor Show. The F430 was succeeded by the 458 which was unveiled on 28 July 2009. Overview Design Designed by Pininfarina in collaboration with Frank Stephenson (Director of Ferrari-Maserati Concept Design and Development), the body styling of the F430 was revised from its predecessor, the 360, to improve its aerodynamic efficiency. Although the drag coefficient remained the same, the downforce was greatly enhanced. Despite sharing the same basic Alcoa Aluminium chassis, roofline, doors, and glass, the car looked significantly different from the 360. A great extent of Ferrari heritage was included in the exterior design. At the rear, the Enzo's tail lights and engine cover vents were added. The car's name was etch ...

Lamborghini Aventador
The Lamborghini Aventador () is a mid-engine sportscar produced by the Italian automotive manufacturer Lamborghini. In keeping with Lamborghini tradition, the Aventador is named after a Spanish fighting bull that fought in Zaragoza, Aragón in 1993. The Aventador is the successor for the Murciélago and was made by hand in Sant'Agata Bolognese, Italy. History Launched on 28 February 2011 at the Geneva Motor Show, five months after its initial unveiling in Sant'Agata Bolognese, the vehicle, internally codenamed LB834, was designed to replace the then-decade-old Murciélago as the new flagship model. Soon after the Aventador's unveiling, Lamborghini announced that it had sold 12 cars, with deliveries starting in the second half of 2011. By March 2016, Lamborghini had built 5,000 Aventadors, in just five years. Specifications and performance Specifications Engine The Aventador LP 700–4 used Lamborghini's 60° V12 engine weighing 235 kg. Known internally as th ...

Direct-shift Gearbox
A direct-shift gearbox (DSG, german: Direktschaltgetriebe) is an electronically-controlled, dual-clutch, multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout (depending on engine/drive configuration), with automated clutch operation, and with fully-automatic or semi-manual gear selection. The first dual-clutch transmissions were derived from Porsche in-house development for the Porsche 962 in the 1980s. In simple terms, a DSG automates two separate "manual" gearboxes (and clutches) contained within one housing and working as one unit. It was designed by BorgWarner and is licensed to the Volkswagen Group, with support by IAV GmbH. By using two independent clutches, a DSG can achieve faster shift times and eliminates the torque converter of a conventional epicyclic automatic transmission. Overview Transverse DSG At the time of launch in 2003, it became the world's first automated dual-clutch transmission in a series-production car, i ...
