Electrically-applied transmission brake band

摘要

A brake band and apply mechanism includes a brake drum and a brake band surrounding the drum. The brake band is enforced into engagement and disengagement with the drum through an apply mechanism which includes a rotary electric motor and a linear output member. The linear output member is operatively connected with the brake band. A rotary-to-linear transfer or torque to thrust mechanism is disposed between the motor rotary output and the brake band linear input to enforce engagement and disengagement of the brake band. The motor power is only required during apply and release of the band.
