PARKING BRAKE FOR VEHICLE

摘要

PURPOSE: To reduce force for applying a parking brake for a vehicle and force for releasing the brake. CONSTITUTION: This parking brake comprises a lever 1 articulated onto a pin 2, a soleplate 3 and a toggle joint mechanism 8 connected to a cable 9. The toggle joint mechanism 8 includes a connecting rod 10 articulated onto the lever 1. An end of the cable 9 is connected to an end of the connecting rod 10 through a balancer bar 11 translationally movable in a direction parallel to the cable 9. When the brake is applied, the lever 1 is brought into abutment on the soleplate 3 so that direction of force in the connecting rod 10 passes above the pin 2 to keep the lever 1 in the brake applied position. A push rod 16 subjected to a return force F and sliding inside the lever 1 automatically provides safety locking of the brake.
