Field of Invention
The present invention pertains to the field of automobile industry and more particularly it relates to a combined braking system for pedal brake with delay mechanism for two wheeled vehicles which provides an economical and efficient solution for enhancing braking system.
Background of Invention
A brake is a mechanical device or apparatus in automobile vehicles, which inhibits motion by absorbing energy from the moving wheels of vehicle to decelerate the vehicle's momentum for stopping of moving vehicle. A braking system plays a crucial role in improving efficiency of the vehicles and providing auto safety in terms of prevention of road accidents, particularly for high-speed vehicles.
Since the earliest automobiles, a gradual development has been carried out to provide an improved braking systems and methods for automotive vehicles. Since ancient time, various kinds of brakes i.e. wooden block brakes, mechanical brakes, expanding internal shoe brakes, mechanical brakes, hydraulic brakes, disc brakes, anti-lock brakes etc. have been gradually developed to meet the requirements of braking mechanism of vehicles in automobile industry.
In last few decades, a gradual evolution in automobile industry is being carrying out to provide an efficient braking system than that of the existing one. In conventional mechanical drum-brake, the brake shoes are

actuated by a cam, which is attached to the brake linkage and lever. The conventional mechanical drum-brake is defined to mean a braking system in which, when the brake lever is pressed, the cam turns that causes the brake shoes to expand outwards and rub against the drum. Friction between the brake linings and the drum causes the drum to stop rotating; thereby stopping the wheels. When the brake lever released, the retracting springs bring the brake shoes back to their original position. Thus, said mechanical drum brake provides a braking force by causing friction between the brake shoe with linings and drum by using a cable linked with the brake lever.
In prior art vehicle without combi brake, when the rear brake lever (on left handlebar in a scooter) or the brake pedal (foot-operated in a motorcycle) is operated, brake will be applied only on the rear wheel. If the force applied by the rider is high, the rear wheel would lock (because of reduction in rear wheel reaction due to weight transfer to the front during deceleration), leading to an accident.
In the prior art braking system slippery road conditions, gradual and light braking should be done only using combi brake. Severe braking using both brakes or only the front brake in such situations can cause locking of front wheel, and result in loss of control of the vehicle.
The conventional combined braking system, without delay mechanism, includes more number of moving elements which induces frictional force which results in reduced life of the components. Further,

the conventional combined braking system is very complex in design and expensive.
Although, the conventional combined braking systems have been proved to be an advantageous, there is still scope to improve the functionality and performance of the braking system for inducing a customized variable braking force to both of the wheels, i.e. front brake wheel and rear brake wheel simultaneously, by using a single brake-actuating medium i.e. a hand brake lever or a brake lever. Hence, a need yet exists to switch the combined braking system having with an enhanced functionality and performance.
Therefore, it is desperately needed to develop a combined braking system for customized variable load distribution which overcomes the aforesaid drawbacks and limitations of the prior art braking systems.

Other objects, advantages and novel features of the invention will become apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
Fig. 1 depicts a perspective front view of combined braking system for pedal brake with improved delay mechanism for two wheeled vehicles according to the present invention.
It should be noted that the figures are not drawn to scale and that elements of similar structures or functions are generally represented by like reference numerals for illustrative purposes throughout the figures. It also should be noted that the figures are only intended to facilitate the description of the preferred embodiments. The figures do not illustrate every aspect of the described embodiments and do not limit the scope of the present disclosure.
Detailed description of Invention
Before explaining the present invention in detail, it is to be understood that the invention is not limited in its application to the details of the construction and arrangement of parts illustrated in the accompany drawings. The invention is capable of other embodiment, as depicted in different figures as described above and of being practiced or carried out in a variety of ways. It is to be understood that the phraseology and terminology employed herein is for the purpose of description and not of limitation.

Before explaining the present invention, it is to be understood that "a combined braking system" is a generic term commonly used for a braking system, which actuates front brake mechanism and rear brake mechanism simultaneously by using a single brake actuating means, such as a brake lever or brake pedal.
Further, the term "delay mechanism", hereinafter described, being used for delay braking of the front wheel, which enables an initial actuating of the rear brake mechanism and then after it manipulates the front brake mechanism to eliminate skidding of wheels of the vehicles by using torsional elastic member. Further the term "adjustable delay mechanism", hereinafter described, being used for adjusting time for delay braking of the front wheel by using delay slit as per requirement.
It is to be also understood that the term "comprises" and grammatical equivalents thereof are used herein to mean that other components, ingredients, steps, etc are optionally present. For example, an article "comprising" (or "which comprises") components A, B, and C can consist of (i.e., contain only) components A, B, and C, or can contain not only components A, B, and C but also contain one or more other components.
Now, in embodiment shown in Fig.l, a combined braking system (1) according to the present invention comprises a brake pedal (2) having one end integral with a main pivot (3) and a main link (4) a rear brake

actuating means (5) operably connected to the main link (4) through a first hinge point (H1), the brake pedal (2) being pivotable through the main pivot (3) a connecting link (6) pivotably connected to the main link (4) at second hinge point (H2) a front brake actuating link for adjustable delay (7) pivotable through a secondary pivot (8), being pivotably connected to the connecting link (6) through a third hinge point (H3) a front brake actuating means (9) operably connected to the front brake actuating link for adjustable delay (7) at fourth hinge point (H4).
Referring continuous with Fig.l said rear brake actuating means (5) having a rear brake cable holder (10) configured to firmly hold a rear brake cable (11), pivotably connected to the main link (4) through the first hinge point (HI). Further said the front brake actuating means (9) having a front brake cable holder (12) configured to firmly hold a front brake cable (13), connected to the front brake actuating link for adjustable delay (7) through the fourth hinge point (H4) the front brake cable holder (12) includes a delay slit to enable delay actuating of the front brake actuating means (9).
