  • Patent number: 11628907
    Abstract: A cycle braking system is provided where the system comprises a brake sphere engaged with a shaft adjacent to a wheel of a cycle and a brake caliper, where the brake caliper is mounted to a cycle's chassis and aligned around the brake sphere rotor. In one embodiment, the cycle braking system further comprises brake pad(s) with an inner side and a contact side, a brake housing having the brake pad(s) positioned between the caliper and the contact side facing the brake sphere; and the brake caliper connected to a cycle's hydraulic lines.

  • Publication number: 20210229640
    Abstract: A brake sphere apparatus of a spherical braking system is mounted on the axle or drive shaft of a vehicle. A brake sphere is connected to a wheel hub and rotates simultaneously together with the wheel hub. A housing contains the brake sphere, two brake pads on opposing sides of the brake sphere, and two hydraulic shafts respectively driving the two brake pads. Two hydraulic lines are connected to the two hydraulic shafts through the housing, the two hydraulic shafts press the two brake pads against the brake sphere when pressure is applied through the two hydraulic lines. Cooling is provided to cool the brake sphere when torque is applied to said brake sphere to decrease simultaneous rotation of the brake sphere and wheel hub.

  • Publication number: 20200248765
    Abstract: A sphere drive line retarder is presented that is mounted to a drive shaft from an engine. The sphere drive line retarder comprises a sphere rotor mounted to the drive shaft and housed within a retarder housing. The sphere drive line retarded has a piston assembly comprising at least one piston, a brake shoe mounted to each piston, and hemispherical friction material mounted to the brake shoe. The hemispherical friction material is located between the sphere rotor and the brake shoe. Each piston is housed within a piston housing that is hydraulically isolated from the retarder housing. The retarder housing contains hydraulic fluid to cool the sphere rotor.

  • Patent number: 8453811
    Abstract: A spherical braking system mounted on a drive shaft of a vehicle comprising a brake sphere pad positioned just above and below a brake sphere and resting on an at least one segment of a brake housing wherein, the brake housing includes a top segment and bottom segment coupled to mounting dogs by using screws. A hydraulic cap installed on a threaded portion of a hydraulic shaft which is encircled by bushing and coupled near a brake sphere. A plurality of hydraulic lines connected from at least one hydraulic splitter are coupled to the hydraulic cap. When the driver depresses the brake pedal, pistons are forced into fluid chambers in the master cylinder. The resulting hydraulic pressure is transmitted through the hydraulic splitter and hydraulic lines to hydraulic caps which results the vertical movement of the brake pads causes a braking torque to be generated, slowing the rotation of the drive shaft and driven shaft simultaneously, which therefore decreases the speed of the vehicle.
