Electrically driven vehicle including a drivetrain with an electric motor which forms the drive of the vehicle, and a frictionally engaging clutch. The clutch is a normally closed clutch with conical friction elements, which rest against each other in pairs in a closed position and transmit torque.
First claim
Opening claim text (preview).
What is claimed is: 1. Electrically driven vehicle comprising a drivetrain with an electric motor which forms the drive of the vehicle, and a frictionally engaging clutch, wherein the clutch is a normally closed clutch with conical friction elements, which rest against each other in pairs in a closed position and transmit torque, wherein the vehicle comprises a single-speed gearbox, in which the clutch is mechanically integrated. 2. Electrically driven vehicle according to claim 1 , wherein the clutch comprises at least one spring element, which holds the clutch in the normally closed position. 3. Electrically driven vehicle according to claim 1 , wherein the cone angle of the friction elements is less than 30°. 4. Electrically driven vehicle according to claim 1 , wherein the cone angle of the friction elements lies in the range of from 3° to 15°. 5. Electrically driven vehicle according to claim 1 , wherein at least one of the conical friction elements have an organic or metallic friction lining. 6. Electrically driven vehicle according to claim 1 , wherein all of the conical friction elements have an organic or metallic friction lining. 7. Electrically driven vehicle according to claim 1 , wherein the clutch is a wet clutch. 8. Electrically driven vehicle comprising a drivetrain with a frictionally engaging clutch, wherein the clutch is a normally closed clutch with conical friction elements, which rest against each other in pairs in a closed position and transmit torque, wherein the vehicle comprises an electrical control system, a gearbox and an electric motor, wherein the electric motor and the gearbox are designed such that a main drive gear is provided for a driving speed up to 90 km/h. 9. Electrically driven vehicle comprising a drivetrain with a frictionally engaging clutch, wherein the clutch is a normally closed clutch with conical friction elements, which rest against each other in pairs in a closed position and transmit torque, wherein the vehicle comprises an electrical control system, a gearbox and an electric motor, wherein the electric motor and the gearbox are designed such that a main drive gear is provided for a driving speed up to 100 km/h, and beyond this the gearbox is shifted into a secondary drive gear.
