The invention relates to a dynamic force-distributing device. The dynamic force-distributing device has a dynamic three-stage force distribution function, and is especially suitable for being applied to a single-handed braking device of various front and rear wheel form vehicles. The whole braking process can show three-stage functional characteristics such as safety, stability, reliability, fast stopping and the like, so that the problem of accidents caused by improper brake operation is avoided.

A variable output cylinder system includes a housing forming an inner cavity, the housing having a centerline co-axially extending through center of the inner cavity, and a first section secured to a second section, the first section having a sidewall the tapers outwardly relative to the centerline and relative to an opening passing through a thickness of the first section; a piston rod extending through and slidingly engaged with the opening; a piston head rigidly attached to an end of the piston rod; a pliable membrane fixedly secured to an outer surface of the piston head, the pliable membrane forming a sealed chamber within the second section, the pliably membrane forming an area disposed between the of the first section and an outer surface of the piston head; and a second opening extending through a thickness of the second section and configured to provide passage to the sealed chamber. The area disposed between the first section and the outer surface of the piston head increases in size as the piston traverses away from the opening of the first section.

A vehicle brake system operable to simultaneously apply an equal amount of braking pressure to a plurality of tires. The system includes a pair of brake guides, a brake bar secured to the brake guides, and a control bar secured to the brake bar. The control bar is operable to move the brake bar back and forth so that a portion of the brake bar selectively abuts the plurality of tires to apply the braking pressure. The system may be retrofitted to existing vehicles or fitted to new vehicles.

This invention relates to a double linkage safety brake system, which includes at least a brake handle, a base, a rear wheel brake wire, a front wheel brake line, a rear wheel brake and a front wheel brake. Said brake handle is provided with a first connecting rod and a second connection rod, the driving arm of brake handle is provided with a first shaft hole and a second shaft hole, the second shaft hole is an arc-shaped elongated hole, the distance between the first shaft hole and the shaft 200 is smaller than the distance between the second shaft hole and the shaft. A first support shaft is pivoted between the first shaft hole and the first connecting rod, and the outer side of the first connecting rod is connected to said rear wheel brake wire. A second support shaft is pivoted between the second shaft slot and the second connecting rod, and the outer side of the second connecting rod is connected to the front wheel brake wire. In this way, the driver only needs to press the brake once to output a time difference braking force by the first connecting rod and the second connecting rod, and the rear wheel brake and the front wheel brake can generate a time difference braking action; furthermore, the moving arc length of the second connecting rod is greater than the moving arc length of the first connecting rod when the driving arm rotates, so the braking force generated by the second connecting rod is greater than the braking force of the first connecting rod, and the braking force of the front wheel brake is greater than the braking force of the rear wheel brake, to achieve the purpose of safe braking, and can prevent accidents caused by the driver start the front wheel brake first.

A miniature vehicle includes a chassis frame, front and rear wheel assemblies operatively coupled at front and rear ends of the chassis frame respectively, a motorized assembly supported on the chassis frame to power the rear wheel assembly, and a foot steering arrangement operatively coupled to the front wheel assembly. Therefore, the user is able to control the miniature vehicle by the feet of the user to precisely steer and control the miniature vehicle.
