Abstract
A parking brake apparatus comprising a manipulation lever; an actautor; a balance lever connected at its one end through a first coupling member with the manipulation lever so that a manipulated force of the manipulation lever acts on the one end and at its outer end through a second coupling member with the actuator so that an operating force of the actuator acts on the other end, the balance lever having a portion on with a parking brake force acts; relative displacement detecting unit for detecting a relative displacement between the manipulation lever and the actuator; and control means unit for controlling the actuator so that the relative displacement detected by the relative displacement detecting unit is reduced.
Claims7
A parking brake apparatus comprising:
- a manipulation lever;
- an actuator;
- a balance lever connected at its one end through a first coupling member with said manipulation lever so that a manipulated force of said manipulation lever acts on said one end and at its other end through a second coupling member with said actuator so that an operating force of said actuator acts on said other end, said balance lever having a portion on which a parking brake force acts;
- relative displacement detecting means for detecting a relative displacement between said manipulation lever and said actuator;
- and
- control means for controlling said actuator so that the relative displacement detected by said relative displacement detecting means is reduced.
A parking brake apparatus comprising:
- a parking brake manipulation lever for operating and releasing a parking brake;
- an actuator provided to reduce a manipulated force of said parking brake manipulation lever, the actuator being operated by manipulation of said parking brake manipulation lever;
- manipulation switch means for operating and releasing said actuator without manipulating said manipulation lever;
- and
- control means for controlling the operation and release of a parking brake caused by said actuator on the basis of an output of said manipulation switch means.
