PARKING BRAKE HANDLE Russian patent published in 2023 - IPC B60T7/08 

FIELD: military equipment.

SUBSTANCE: invention relates to the field of armored vehicles; it can be used in structures of tanks, infantry fighting vehicles, armored carriers, tractors, other military tracked or wheeled vehicles. A parking brake control handle is made with a groove equipped with an output link made with the possibility of movement in the mentioned groove for automatic change in gear ratio of a parking brake drive. When installing a vehicle on the parking brake, with rotation of the parking brake control handle from an initial position, the output link starts to move along the groove, while a distance from the output link to a center of rotation of the control handle starts to decrease, that is a length of one of arms of the control handle is changed, which means that gear ratio of the handle is changed. The greater control handle rotation is, the more its gear ratio increase, and a force transmitted through the handle to parking brakes also increases, while a mechanic-driver will apply a smaller force to the parking brake handle for installing the vehicle on the parking brake.

EFFECT: obtainment of a structure of a parking brake handle capable of increasing a force applied to it by a mechanic-driver due to an increase in gear ratio of the handle.
