6 FAQs about [Dual clutch energy storage]
Can a two-speed dual-clutch gearbox be used for electric vehicles?
Most electric vehicles today use gearboxes with multiple speeds. The transmission systems on traditional cars using internal combustion engines can be used for electric vehicles. In this paper, the author presents the research result on the gearshift strategy of a two-speed dual-clutch gearbox applied on electric vehicles for energy efficiency.
Does a dual clutch transmission improve acceleration performance and fuel efficiency?
Abstract: Dual clutch transmission (DCT) which can simultaneously improve acceleration performance and fuel efficiency compared to automatic transmissions (AT) and manual transmissions (MT) is one of the most noted studies in recent powertrain applications.
Does clutch actuator reduce fuel efficiency of DCT-equipped vehicles?
However, much of energy consumption of clutch actuator reduces fuel efficiency of DCT-equipped vehicles. In order to reduce energy consumption of these actuators, a method of modifying mechanism and a method of improving it through control have been studied.
Does a multi-gear transmission save energy?
An EV with the multi-gear transmission can enhance both dynamic and economic performances [ 4 ]. The EV with a four-gear transmission can save up to 30% energy. [ 3] shows that only by designing the optimal transmission ratios, energy can be saved up to 15%.
What assumptions are used in disk clutch design?
Two common assumptions are applied to the development of steps for disk clutch design, that is, uniform rate of wear and uniform pressure distribution assumptions.
What is a pure EV clutch?
In pure EV, the clutch is used to connect the motor and the gearbox. Shaft connection can be realized via a series of techniques, such as mechanical friction, hydraulic type or pneumatic ways, or by their combination. The clutches considered here are of the friction type.
