Mazda CX-5 Service & Repair Manual: Brake Pedal
Purpose/Function
-
An intrusion-minimizing brake pedal has been adopted to the brake pedal to provide for a measure of safety in the event of an accident.
-
The intrusion-minimizing brake pedal mechanism reduces impact to the lower extremities of the driver by minimizing the amount of rearward brake pedal thrust in a frontal collision.
Construction
-
The intrusion minimizing brake pedal mechanism is structured on the brake pedal and consists of the following parts.
-
Pedal arm
-
Lever
-
Pin A
-
Pin B
-
Pin C
-
Bracket
Operation
During normal braking
-
When the brake pedal is depressed, the pedal arm rotates at the pin A fulcrum point, and the pedal depression force is transmitted to the fork of the power brake unit.
-
This pedal depression force pushes in the fork to operate the brakes.
Intrusion-minimizing operation
-
In a frontal collision, the brake pedal is forced rearward by the movement of the dashboard.
-
In response to this, force in the direction of X is applied to the brake pedal lever because the dashboard member and brake pedal lever interfere.
-
With the addition of force in the direction of X, pin C releases from the lever, and the lever rotates around the pin B fulcrum point.
-
When the lever rotates, it obstructs pin A at the fulcrum point of the pedal arm.
-
If the pedal rotates further, pin A separates from the bracket (notch), and the pedal is freed.
-
By freeing the pedal arm, the force applied to the lower extremities is reduced.
