Problems solved by technology

[0004] Increasing the number of pistons can lead to problems implementing a parking brake system integrated with brake pistons
Reasons for this may include, for example Figure 5b The spindle / nut arrangement shown in should be implemented on both pistons associated with the wheel, or there is a risk of uneven wear and / or uneven application of the brakes, which could cause other operational problems such as binding the pistons
[0005] However, simply increasing the diameter of the piston is limited by the width of the brake pad
[0006] Also, increasing the pressure at which the piston operates to increase the force also risks deforming the pad due to the presence of highly localized forces (at the piston), which can also lead to uneven wear and other operational problems

Embodiment Construction

[0035] In the following description, numerous specific details are set forth in order to clearly describe various specific embodiments disclosed herein. However, one skilled in the art will understand that the presently claimed invention may be practiced without all of the specific details discussed below. In other instances, well-known features have not been described so as not to obscure the invention.

[0036] figure 1 An embodiment of a braking system is shown in which a piston with an extended seat 5 is positioned in a caliper 6 in which the extended seat 5 can be pressed against a brake pad 7 which is in the The brake is pressed against the rotor 8 during operation of the brake.

[0037] figure 2 An embodiment of the brake caliper 6 is shown with a piston and an extended base 5, wherein there are two extensions 9 of the base. In some embodiments, the one or more extensions 9 may be along the axis of the brake pad 7 (eg the long axis 12 of the brake pad 7 , which ma...

Abstract

The invention relates to the base of an oversized brake piston. The present disclosure describes a brake piston. The brake piston is configured for a disc brake system, the piston includes: a main body, the outer width of which is perpendicular to the central axis; a base, the base is arranged at the distal end of the piston, wherein the base is configured to exerting a force on a brake pad during actuation of the disc brake system; the base having a face configured to contact the brake pad, the face having a length and a width, wherein the length is greater than the The outer width of the body is long, and the length is greater than the width.

Description

technical field [0001] The present disclosure relates to pistons for disc brake systems. Background technique [0002] The present disclosure relates to, for example, disc brake caliper pistons and piston systems for various alternate tools including automobiles, trucks, aircraft, and the like. Embodiments of the present disclosure include pistons with oversized bearing surfaces for contacting the brake pads, a retraction system for retracting the piston portion, and / or a sealing system inside the piston. [0003] As the vehicle becomes larger and heavier, greater braking force may help stop the vehicle. Increased braking force can be obtained in a number of ways, such as by pushing the brake pedal harder; by increasing the hydraulic advantage within the braking system to obtain more pressure at the brake pistons; by increasing the number of brake pistons to Obtain increased braking force for a given hydraulic pressure or increase the diameter of the piston to obtain incre...
