Names for specific types of semi-automatic transmissions include clutchless manual, [3] auto-manual, [4] [5] auto-clutch manual, [6] [7] and paddle-shift transmissions. [ 8 ] [ 9 ] [ 10 ] These systems facilitate gear shifts for the driver by operating the clutch system automatically, usually via switches that trigger an actuator or servo ...
They are much less common than motorcycles with conventional manual transmissions, typically use a centrifugal clutch, and are mostly found on smaller motorcycles, such as minibikes, underbone (step-thru) motorcycles (e.g., the Honda Super Cub), smaller dirt bikes (such as pit bikes), and various (mostly older) mopeds and motor scooters. Semi ...
semi-automatic transmissions are also in use; where the driver's input is still required for shifting gears, but the clutch system is controlled and operated automatically. These systems are mostly found on smaller dirt bikes (e.g., minibikes; such as pit bikes), underbones, many older mopeds and scooters, and various other types of motorcycles.
Clutch control is the controlling of the speed of a manual transmission vehicle by partially engaging the clutch plate, using the clutch pedal instead of (or in conjunction with) the accelerator pedal. The purpose of a clutch is in part to allow such control; in particular, a clutch provides transfer of torque between shafts spinning at ...
A scooter (motor scooter) is a motorcycle with an underbone or step-through frame, a seat, a transmission that shifts without the operator having to operate a clutch lever, a platform for their feet, and with a method of operation that emphasizes comfort and fuel economy. Elements of scooter design were present in some of the earliest ...
There is no clutch of any kind between the CVT and the crankshaft; it is engaged via a centrifugal clutch at the rear pulley in the same fashion as Vespa Grande, Bravo, and variated Ciao model, as well as Honda Camino/Hobbit scooters/mopeds. An electric starter, backup kick-starter, and rear brake hardware is also housed in the swingarm. [2]
A chainsaw's clutch. The chain wraps around a sprocket behind the clutch that turns with the outer drum. The input of the clutch is connected to the engine crankshaft while the output may drive a shaft, chain, or belt. As engine revolutions per minute increase, weighted arms in the clutch swing outward and force the clutch to engage. The most ...
Flexibility. As power transfer from the engine-driven pump to the hydraulic motor(s) is through the medium of flowing oil, the motor(s) can be mounted in otherwise-inconvenient locations by using hoses to convey oil from the pump to the motor(s), thus simplifying the design of all-wheel drive articulated vehicles. Smoothness.
