Title:
MOTOR OVERSPEED PREVENTING DEVICE FOR HYBRID TRANSMISSION
Document Type and Number:
Japanese Patent JP2006044348
Kind Code:
A
Abstract:

To provide a device capable of preventing overspeeding of a motor/generator in time of deceleration, in a state where an engine clutch is released and where the motor/generators are set in non-control.

When a lever OR1 is turned about large output Out (a point D) having large inertia as shown in Figure to allow the overspeed of the motor/generator MG2 in time of the rapid deceleration, in a state with the engine clutch E/C released and the motor/generators MG1, MG2 in non-control state, a low-brake L/B connected to a ring gear R2 positioned on the side of a sun gear S2 related to the motor/generator MG2 to be prevented with the overspeed, as compared to a carrier C related to the out Out is made to be slip-connected. Thereby, the ring gear R2 related to the low brake L/B is reduced, as shown by the arrow X1, as a result, the rotational speed of the motor/generator MG2 is reduced, as shown by the arrow X2, and a rotation speed of the motor/generator MG1 is increased, as shown by the arrow X3 to prevent the overspeed of the motor/generator MG2.
