FIELD OF THE INVENTION
The present invention relates to the braking system. Specifically, the present invention relates to auto adjustment and auto alignment of brakes, thereby improve the braking efficiency and improve brake life.
BACKGROUND OF THE INVENTION
Generally, the braking system of a vehicle is attached to the wheels associated with the axle. The axle can be live or dead axle. Due to braking operation, the braking system undergoes wear and tear. Said wear and tear is uneven in the braking system. Due to uneven wear and tear of the braking system, reduces the braking efficiency. In an annular piston brake having the pre-defined running gap clearance between the piston and the friction disc. The friction disc wears due to actuation of brakes.
Therefore, the running gap clearance between piston and the friction disc increases. Wherein the running gap clearance is uneven. The uneven running gap clearance leads to inefficient braking of brakes. Sometimes this lead to swaying of vehicle.
U. S. Patent 4077500 discloses an annular single piston brake arrangement for selective holding engagement of a rotatable member of a drive train. The brake arrangement includes a support structure, an annular brake piston axially reciprocably and nonrotatably mounted within the support structure, a plurality of springs mounted intermediate the support structure and the brake piston for biasing it concentrically toward peripheral brake holding engagement of the rotatable member, a fluid retractor for holding the brake piston in a disengaged condition overcomingly against the action of the springs, and a fluid actuator for biasing the brake piston concentrically towards peripheral brake holding engagement of the rotatable member. When the brake is actuated the rotatable member is engaged by the piston. Due to friction between the rotatable member and the piston, wear and tear occurs. The wear and tear is uneven on the surface of the rotatable member and thus the braking efficiency is reduced and the brake life is shortened. This patent fails to remedy the shortcomings of uneven wear and tear viz shorter brake life and reduced braking efficiency.
The U. S. Patent 4562902 discloses a brake system for an off-highway vehicle which includes a fluid pressure actuated multi-disc brake and a fluid pressure control system. Engagement of the multi-disc brake is effected by a fluid operated piston having multiple effective pressure areas. Fluid pressure applied to a certain of the effective pressure areas urges the piston in a brake applying direction; fluid pressure applied to the other of the pressure areas urges the piston in a brake releasing direction. The fluid pressure control system controls the communication of pressurized fluid to the effective pressure areas to provide both the brake applying and brake releasing functions. Redundant fluid pressure circuits supply pressurized fluid to the brake applying effective pressure areas. In the event of failure, the control system is operative to interrupt fluid flow to the failed circuit. However, this invention presents the fluid operated annular piston brake. But this fails to remedy the shortcomings of reduced braking efficiency and shortened brake life due to uneven wear and tear of the disc of the braking system. Furthermore, the pistons are to be adjusted manually for effective actuation of brake for the same fluid pressure, due to the wear and tear of the disc.
Therefore, for the above reasons there is need in art to automatically adjust the engaging piston according to the wear and tear of the braking/friction plate/disc. Which actuates the brake and automatically adjust the engaging piston to brake the vehicle efficiently and also improve the brake life. Also, it reduces the vehicle down time in adjusting the brake for better efficiency.

Another of the present invention is to provide a braking system which automatically adjust and aligns the brakes, for improved service life.
Further object of the present invention is to provide a braking system which automatically adjust and aligns the brakes, to have improved braking efficiency.

DETAILED DESCRIPTION OF THE INVENTION
A braking system (101) having auto-aligning and auto-adjusting brakes, comprises of, at least a pedal (102a, 102b);at least a cylinder (103a, 103b), wherein each of the pedal (102a, 102b) is appropriately affixed with each of the cylinder (103a, 103b);a fluid reservoir (104), said fluid reservoir (104) supplies and receives fluid to and from the cylinder (103a, 103b); and, at least a brake assembly (105a, 105b), said the brake assembly (105a, 105b)is positioned on each end of an axle (106) to which a plurality of wheels (107) are associated, wherein said brake assembly (105a, 105b) is fluidically connected to said cylinder (103a, 103b).
Said brake assembly (105a, 105b) comprises of a housing (108); a plurality of discs (109), said plurality of discs (109) are rotatably accommodated in the housing (108) and coupled to the axle (106); a sealing (110), said sealing (110) is affixed on the annular piston (111) to adjust the uneven running gap clearance due to uneven surface of said discs (109), wherein the sealing (110) having a annular portion; and a piston (111) reciprocatingly accommodated in the said annular portion of the sealing (110)..
Said axle can be a live axle or dead axle. Furthermore, said axle can be a direct drive axle or a driven by drive axle.
Wherein the sealing having a roll back seal mechanism. Wherein the said sealing adjust itself to minimise the running gap clearance between piston and the plurality of discs. This adjustment is done appropriately as said discs wear.
In an embodiment, the vehicle is having a direct drive axle. The braking system of the said vehicle comprises of a pedal connected with a cylinder. A brake assembly is affixed on both the ends of the axle. When the pedal is pressed fluid from the cylinder is gushed to the brake assemblies equally. Said fluid provides thrust to the pistons in the brake assemblies. Due to thrust on piston, the rotating speed of the plurality of discs in each brake assembly is reduce, which in turn reduce rotating speed of the axle. Thus the vehicle’s brake is applied to decelerate or stop the vehicle from its original motion. The sealing in the brake assembly automatically adjust to the uneven surface on the plurality of discs. Thus the brake of the braking system is automatically adjusted and aligned according to the wear and tear of the discs. When the pedal is depressed, due to drop in pressure in fluid and due to roll back mechanism of sealing, the pistons are pushed back to its original position. The said fluid also traverses back to the cylinder.
In another embodiment, the vehicle is having a direct drive axle. The braking system of the said vehicle comprises of 2 pedals and 2 cylinders. Each pedal is connected to each cylinder. The brake assembly is affixed on each end of the axle. Wherein each brake assembly is fluidically connected with each cylinder. When a first pedal is pressed, fluid from the first cylinder gushes to the first brake assembly and actuates the first brake assembly to stop or decelerate vehicle from its motion. Similarly, when a second pedal is pressed, fluid from the second cylinder gushes to the second brake assembly and actuates the second brake assembly to stop or decelerate vehicle from its motion. Furthermore, when the both first and second pedal is pressed, based on the pressure applied on the respective pedal, appropriate amount of fluid from its respective cylinder is displaced to the respective brake assembly. The brakes are actuated. When the brake pedal(s) are depressed the fluid actuating the brakes, traverses back to the reservoir through the cylinders.
