DESCRIPTION
























FIELD OF THE INVENTION

The present invention relates to braking systems for vehicles and more particularly to an improved braking system control mechanism primarily designed for use on two-wheeled vehicles operated by a single lever caliper.



BACKGROUND OF THE INVENTION

Conventionally, automobile braking was done mechanically and a single lever operated the brakes on all of the wheels. The braking systems in bicycles and the like usually involve a hand lever on each end of the handle bars such that one hand lever operates the front brake and the other hand lever operates the rear brake, allowing differential pressure to be applied.

Braking systems have been developed which are capable of braking a wheel very efficiently without locking the wheel during braking. Such systems comprised of a master cylinder, a wheel brake hydraulically coupled with the master cylinder, a sensor for sensing angular deceleration and a modulator in the hydraulic coupling between the master cylinder and the wheel brake which is controlled by the sensor. The brakes in vehicles usually involve a single actuating lever, i.e. brake pedal which in turn hydraulically operates individual brake pads at each of the four wheels.

There are two different types of brake systems drums and discs braking systems. A disc brake system consists of a brake disc and two caliper-mounted brake pads that can be forced to grip the disc between them. Drum brakes are made up of two brake shoes that can be forced against the inner surface of a brake drum. Braking then occurs as the applied force increases the friction between the pads and the disc or the shoes and the drum, respectively. The braking force acts in the direction of rotation of the wheel, and the total braking force depends on the coefficient of friction between the tire and the road and the force pressing the tire against the road.

US 20100200340 A1 discloses a braking device is designed to be mounted on a bicycle frame C with at least one wheel R with a rim (10), including a fixed support (12), two rigid arms (14G, 14D) that can move relative to the fixed support (12), and two elastic return links (16G, 16D) that are integral with the fixed support (12). The device is characterized in that each arm (14G, 14D) includes a friction member (22G, 22D) that is provided to interact with the rim (10) at the level of its lower end (20G,20D), and a finger (24G, 24D) at the level of its upper end (18G, 18D); and each arm (14G, 14D) is connected to the fixed support (12) by the elastic return link (16G, 16D) that is interposed between its two upper ends (18G, 18D) and lower ends (20G, 20D) and the fixed support (12).

US 4773510 discloses a pair of hand brakes for a bicycle, each attached to a single actuating member in a physical fashion such that the one brake is preferentially actuated regardless which of the handle members is engaged.

US 4267746A discloses a single hand operated actuator for effecting operation of two devices such as the front and rear caliper brakes of the bicycle or the like .the actuator includes a base adopted to be secure the handle bars of the bicycle and having two broaden sliding wires or cable linkages.

There also exists a product of Honda Company named as combi brakes, wherein both rear and front tires are locked with single lever. The control mechanism of combi brakes varies as it is limited to only two tires. Conventional brakes for motor driven vehicles involve a single actuating lever hat is brake pedal which in turn hydro operates individual brake pads at each of the four wheels.

Some of the braking systems use a caliper operated by means of a cable controlled by the connected braking lever on the handlebar. The caliper mounted in a fixed manner does not allow self-centering thereof during braking, causing undesirable friction when the linings are in the resting position.

Despite the aforementioned drawbacks, there is seen a need for an improved braking system control mechanism operated with single lever caliper for plurality of tires and can be easily employed on vehicles to include but not limited to. The improved braking control mechanism controls the removal of brakes during motion, thereby generating an effective braking effect even with a small movement of the control wire.
