The invention discloses a
disc brake braking
leaf spring. The
disc brake braking
leaf spring comprises a
leaf spring body of an inverted V shape; the leaf spring body is formed by connecting two wing sheets, installation holes are formed in the upper parts of the wing sheets, and the two wing sheets are connected into a whole through connection parts arranged at the top end. The
disc brake braking leaf spring is characterized in that a limiting strip used for abutting against the inner wall of a disc
brake pump body is arranged at the top end of the leaf spring body, extends towards one side and is arranged towards the driving direction during working conditions. In the braking process, when
brake pads are driven to move by a
brake disc, the brake disc exerts force in the tangential direction of the disc and torque opposite to the rotation direction of the disc on the brake pads, and if fast inching braking is executed, the brake pads and fixing pins continuously collide with each other and generate the collision
noise due to the connection gaps. By designing the limiting strip, the gaps between the braking pads and the fixing pins are eliminated in the braking process, the braking pads and the fixing pins are prevented from colliding with each other in the braking process, and therefore the braking process is more stable, and the
noise generated by collision of the braking pads and the fixing pins can be lowered or eliminated.
