Renault turns its factory in Seville, as defined by the brand itself, into its “global production center for hybrid gearboxes” by announcing that with the award of a new gearbox to the plantthe so-called DB35this will become the only one in the group that will supply gearboxes to all Renault hybrid cars in the world.
The news has come from the hand of Juan Manuel Moreno Bonilla, president of the Junta de Andalucía, who in a meeting with the directors of the Sevillian plant has confirmed that the Seville Refactory (as Renault calls this factory) will be in charge of internal code gearbox production DB35, a box with which Renault registered more than 150 patents when designing it due to its innovative design.
It is, more specifically, the gearbox that takes place in hybrid and plug-in hybrid cars from Renault’s E-Tech range, such as the Clio, Capture, Megane and Arkana.
This news adds to the last one that had the Sevillian Renault factory as the protagonist when in April it was confirmed that it would be in this plant that the gearbox for all versions of the new Renault Austral would be manufactured, a model that will arrive only in light hybrid and conventional hybrid format, as well as other transmissions that were awarded in March 2021.
In addition to this, the reducer for the electric Renault Mégane is also manufactured in Seville, while the engine is produced by Renault at its French factory in Cléon.
will be the next September when the Seville ReFactory begins mass-producing this gearbox, for which a new assembly line will need to be set up within the factory,
The DB35 is a very particular gearbox for hybrid cars
This is a very good gearbox. technically complete, since it does not have a clutch to use as it happens in other hybrid car transmissions. Instead, Renault has managed to design a gearbox in which the electric motors themselves, which work in conjunction with the transmission, act as a clutch. That is why It also doesn’t have synchronisers. as if it has a conventional gearbox.
The operation of this system, then, relies on two of the three electric motors. As there is no clutch, starting from a standstill is always in 100% electric mode. The main electric motor is responsible for this, and when due to driving circumstances it is necessary for the gasoline engine to start, the smaller electric motor is responsible for starting the thermal block.
The gearbox is responsible for staggering the power of a block of 1.6 liters of displacement and 90 CV of power, while the battery from which the electric motors are fed has a capacity of 1.2 kWh, and is located under the trunk floor in the case of the Clio, while in the rest of the models it takes place under the rear bench seat.
