Title:
CLUTCH DEVICE AND COLLISION MITIGATION MECHANISM
Document Type and Number:
Japanese Patent JP2022043988
Kind Code:
A
Abstract:
To improve the fuel efficiency and reduce the environmental load while mitigating damage from a collision.SOLUTION: When a collision occurs, a driving force of a drive shaft 12 is transmitted to a reversing high-load multiple disk clutch 850 via an inertia absorbing gear mechanism 840. Then, the driving force is transmitted to a gear 862 via a gear 866, the inertia is absorbed, and the driving force acts to rotate an output shaft 14 at a low speed. On the other hand, when the gear 862 rotates, a regenerative/backing up motor 864 also rotates, and so-called regenerative driving is also performed. Due to these operations, the output shaft 14 rapidly decreases in rotation speed, and goes into a rotation stopping state from a forward rotating state. Then, when a vehicle speed sensor 304 detects that the vehicle speed has reached "0", the regenerative/backing up motor 864 is driven, the output shaft 14 is driven to rotate reversely for several seconds, and thereafter driving of the regenerative/backing up motor 864 is stopped.SELECTED DRAWING: Figure 10
