  • Patent number: 8567570
    Abstract: A brake assembly for use with a portable generator includes a frame, a shaft, a brake surface, and an actuator. The frame is designed to be attached to the portable generator. The shaft is supported by the frame, and the brake surface is connected to an end of the shaft. The actuator includes a foot pedal, a cam, and a pivot, where the pivot is coupled to both the foot pedal and the cam and provides for rotation of the foot pedal and the cam about a portion of the frame. The cam of the actuator translates the shaft between a released position and a braked position during operation of the brake assembly.

  • Patent number: 7900753
    Abstract: A braking ratio device for a remote control model is composed of a suspending arm and a ratio device. The suspending arm is fixed with a shaft of a servo motor, having a controlled member formed at its one side and a driving member extended out from one end of the controlled member. The ratio device is provided with a pivotal base pivotally mounted on the controlled member, and a ratio base connected with the pivotal base to be able to move axially. A front brake connecting rod and a rear brake connecting rod are respectively inserted through two sides of the ratio base, to alter the distance between the front brake connecting rod and a front braking set, and also the distance between the rear brake connecting rod and a rear braking set, for creating a time difference of braking for the front and the rear braking sets.

  • Patent number: 7316298
    Abstract: This invention relates to gravity reactive braking systems. According to the invention there is provided a brake system to control speed in a forward direction for descending inclined surfaces and a brake system for controlling rollback when ascending an inclined surface. The speed pacer braking assembly includes a downhill activator for selectively engaging a disc brake system when a predetermined inclined is reach. The anti-rollback assembly comprises a pair of graded brake cam structures operatively disposed adjacent wheels wherein the natural pull of gravity and the configuration of the cams operate to allow passage of wheels in both directions when on flat surfaces and in only a single direction when on an incline. When on an incline, gravity operates to dispose cams relative to the wheels such that rotation of wheels in one direction is hindered by a thickening of cam body caused by rotation of cam about its axis.

  • Publication number: 20020005619
    Abstract: A wheelbarrow braking system helps control speed of a wheelbarrow on a slope. A braking mechanism, such as a drum brake, a disc brake assembly or a caliper brake for the wheel, has a control cable and a twist-type control handle, which is installed in place of one of the regular handle grips. A simple twist of the handle operates the brake cable to activate the braking mechanism. A brake drum is mounted on one side of the single wheel by either bolting or welding the brake drum mounting plate to the rim of the wheel. For a two-wheeled wheelbarrow, a brake drum is mounted in the center of the axle upon which the two wheels are supported. Simply twisting the handle activates the braking system. This allows the operator to maintain contact with both handle bars during braking, facilitating greater control of the wheelbarrow. Caliper brakes may be used in the wheelbarrow braking system. A frame mounted caliper presses against a disc mounted on the wheel of the wheelbarrow to slow the wheelbarrow by friction.
