Safety Warnings
SAFETY INFORMATION Doc ID: 192-297A Doc Revision: 010418 Improper installation, service or maintenance of this product can cause death, serious injury, and/or property damage. • Only a trained and qualified mechanic should install this product. • Read these directions thoroughly before installation. • For assistance or additional information, please call Rekluse Motor Sports. Failure to become familiar with Rekluse auto clutch operation before use can cause death, serious injury, and/or property damage. • Completely familiarize yourself with the operation of the Rekluse auto clutch. • Do NOT allow anyone unfamiliar with the operation of the Rekluse auto clutch to operate a Rekluse auto clutch equipped motorcycle. • Do NOT attempt to ride a Rekluse auto clutch equipped motorcycle on public roads until you are completely familiarized with the operation of this product. • First practice riding Rekluse auto clutch equipped motorcycles in a safe area free of obstructions. A Rekluse auto clutch can engage suddenly and cause death, serious injury, and/or property damage. Loss of control can result from sudden and unexpected engagement of the clutch from a free-wheeling state. Rear tire may slow from the engine's compression braking effect and cause the rear tire to skid. • Always select a suitable transmission gear for your ground speed, engine RPM and terrain. • Release the clutch lever slowly and apply a small amount of throttle to control engine compression braking after downshifting. See installation and/or user’s guide for more information about free-wheeling. Rekluse auto clutch can make your motorcycle appear to be in neutral when in gear, even when the engine is running and clutch lever released. -

FE Analysis of a Dog Clutch for Trucks with All-Wheel-Drive FE-Analys Av En Klokoppling För Allhjulsdrivna Lastbilar

När en lastbil kör på halt eller löst väglag kan hjulspinn uppstå vid bakhjulen. Om föraren kopplar in allhjulsdriften när hjulen börjat slira uppstår en relativ rotationshastighet mellan halvorna i klokopplingen. Om denna relativa rotationshastighet är för hög kommer halvorna i kopplingen studsa mot varandra innan de kopplas ihop eller inte koppla ihop alls. För att undvika detta problem har klokopplingens tandgeometri modifierats. FE simuleringar är gjorda på den ursprungliga modellen samt alla nya modeller för att ta reda på vilken som kopplar vid högst relativa rotationshastighet. Resultaten visar att förbättringar kan göras. Enkla modifieringar på avfasningarnas avstånd och vinklar visar att klokopplingen kan klara upp till 120 rpm i relativ rotationshastighet jämfört med den ursprungliga modellen som endast klarar 50 rpm. Nyckelord Klokoppling, Allhjulsdrift, FE-analys Abstract (in English) The thesis is carried out in order to improve the transfer case in trucks with all-wheel-drive. -

Received: 14 July 2020; Accepted: 10 August 2020; Published: 17 August 2020 Abstract: Electric vehicles (EV) are becoming more common mobility in the transportation sector in recent times. The dependence on oil as the source of energy for passenger vehicles has economic and political implications, and the crisis will take over as the oil reserves of the world diminish. As concerns of oil depletion and security of the oil supply remain as severe as ever, and faced with the consequences of climate change due to greenhouse gas emissions from the tail pipes of vehicles, the world today is increasingly looking at alternatives to traditional road transport technologies. EVs are seen as a promising green technology which could lead to the decarbonization of the passenger vehicle fleet and to independence from oil. There are possibilities of immense environmental benefits as well, as EVs have zero tail pipe emission and therefore are capable of curbing the pollution problems created by vehicle emission in an efficient way so they can extensively reduce the greenhouse gas emissions produced by the transportation sector as pure electric vehicles are the only vehicles with zero-emission potential. -
