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, that the spindle / nut arrangement shown in Figure 5b should be implemented on both pistons associated with the wheel, or that there is a risk of uneven wear and / or uneven application of the brakes, which could lead to issues such as binding Other operational issues like 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 embodiments disclosed herein. However, it will be understood by those skilled in the art 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 in order 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 in turn The brake is pressed against the rotor 8 during operation of the brake.

[0037] figure 2 An embodiment of a 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, such as the long axis 12 of the brake pad 7, whi...

Abstract

The invention relates to an oversized brake piston footing. A brake piston is described. The brake piston is configured for use in a disk brake system, the piston comprising: a body having an outsidewidth perpendicular to a central axis; a footing disposed at a distal end of the piston; wherein the footing is configured to exert force on a brake pad during actuation of the disk brake system; thefooting having a face configured to contact the brake pad, the face having a length and a width, wherein the length is longer than the outside width of the body, 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, for example, to disc brake caliper pistons and piston systems for use in various alternative tools including automobiles, trucks, aircraft, and the like. Embodiments of the present disclosure include a piston with an oversized bearing surface for contacting a brake pad, a retraction system for partially retracting the piston, and / or a sealing system inside the piston. [0003] As vehicles become larger and heavier, greater braking force can help stop the vehicle. Increased braking power can be achieved in a number of ways, such as by pushing the brake pedal harder; by increasing the hydraulic advantage within the brake system to achieve greater pressure at the brake pistons; by increasing the number of brake pistons to To obtain increased braking force for a given hydraulic pressure or to increase the diameter of the piston ...
