Three-speed sliding-gear non-synchronous transmission Non-synchronous "crash" gearbox; commonly used today in semi-trucks and tractors, and formerly used in automobiles pre-1950s. A non-synchronous transmission, also called a crash gearbox, is a form of manual transmission based on gears that do not use synchronizing mechanisms. They require ...
In April 2021, Fiat launched the E-Ducato, which had been co-developed with package delivery firm DHL. Ducato gliders are assembled at the Fiat Sevel Sud factory in Atessa, then shipped to Fiat Mirafiori in Turin, where they are fitted with a drivetrain developed by SolarEdge. Estimated maximum production capacity is 1,000 vehicles per month. [32]
In most vehicles with a manual transmission, the driver selects gears by manipulating a lever called a gear stick (also called a gearshift, gear lever or shifter). In most automobiles, the gear stick is located on the floor between the driver and front passenger, but some cars have a gear stick that is mounted to the steering column or center ...
The average manual car driver takes between 500 ms and 1 s to perform vertical gear changes (i.e. 1st-2nd, 3rd-4th, 5th-6th) and 1 - 2 s to perform horizontal gear changes (i.e. 2nd-3rd, 4th-5th). Shift time is also dependent on gear throws (distance between gears), ease of movement, ergonomics of the gear stick , and gearbox condition.
Float shifting can reduce clutch wear because it is used so much less (only for starting from a standstill). Conversely, improper engagement of a gear (when the engine and transmission speeds aren't matched) can cause wear on the synchros and lockouts, and damage the gears by physically grinding them together due to a difference in speed.
The term gear stick mostly refers to the shift lever of a manual transmission, while in an automatic transmission, a similar lever is known as a gear selector. A gear stick will normally be used to change gear whilst depressing the clutch pedal with the left foot to disengage the engine from the drivetrain and wheels.
Before the introduction of transmission synchronizers in 1927, [2] double clutching was a technique required to prevent damage to an automobile's gearing during shifts. Due to the difficulty and most often unnecessary redundancy involved in the technique, coupled with the advent of synchronized gearing systems, it has largely fallen into disuse in light vehicles.
The C725 is a 7-speed version developed for engines up to 250 N⋅m (180 lbf⋅ft) of maximum torque and intended only for front-wheel-drive vehicles and transverse engines and is produced in China by the GAC Fiat joint-venture. Three FCA models currently have this transmission as an option, the Fiat Ottimo, the Fiat Viaggio, and the Alfa Romeo ...
