Abstract
Official abstract text for this publication.
Parking brake assembly for a transmission in a vehicle with an electric actuation of the parking brake via a mechanism and with an emergency actuator with a lift magnet on a spring accumulator for application of the parking brake. The spring accumulator has a pawl rotatable about a pivot point connected to the lift magnet and a mass element connected to the pawl and rotatable about a second pivot point.
First claim
Opening claim text (preview).
What is claimed is: 1. A parking brake assembly for a transmission in a vehicle comprising an electric actuator configured for an electric actuation of the parking brake via a mechanism and with an emergency actuator allowing actuation with a lift magnet and a releasable spring accumulator for application of the parking brake, wherein the spring accumulator has a pawl rotatable about a pivot point connected to the lift magnet and a mass element connected to the pawl and rotatable about a second pivot point. 2. The parking brake assembly according to claim 1 , wherein the spring accumulator can be triggered via the pawl with a first rotary movement, wherein the twist of the pawl causes a second rotary movement of the mass element with an inert mass. 3. The parking brake assembly according to claim 1 , wherein the mass element counters a vehicle-induced acceleration of an armature of the lift magnet. 4. The parking brake assembly according to claim 1 , wherein the mass element engages with a ball engagement in the pawl and executes a rotary movement about a rotary element hinged onto the housing of the spring accumulator.
