FIELD OF THE INVENTION
The present invention relates to a hydraulic braking system for efficient braking
of temple cars.
BACKGROUND OF THE INVENTION
A Temple car is a huge wooden chariot used to carry representations or idols of
gods. The car is usually used on festival days, when a huge gathering of people
pull the car. The temple cars have a very rich history, dating back to the very old
and ancient times. The tempfe car also has a very significant importance in the
history of a culturally diversified nation like our country.
During the operation of a temple car, a huge gathering of people, numbering
around 500 is employed for pulling it. The total weight of the temple car may
vary in the range of 50 tonnes to about 300 tonnes. Large wooden logs are
placed under the wheels to bring about any changes in the direction of motion or
to bring the temple car to a standstill.
According to prior art, there is not any motion arresting mechanism available for
such a huge structure. As a result, it becomes very difficult to stop a temple car
that is in motion, which raises various safety related issues.

OBJECTS OF THE INVENTION
It is therefore an object of the invention to propose a hydraulic braking system
for efficient braking of temple cars.
Another object of the invention is to propose a hydraulic braking system for
efficient braking of temple cars.
A further object of the invention is to propose a hydraulic braking system for
efficient braking of temple cars, which enables a risk-free sudden stoppage of a
temple car.
SUMMARY OF THE INVENTION
According to the invention, the hydraulic braking system comprises three braking
units, one each for the two front wheels and a combined unit for both the rear
wheels. To allow smooth turning of the temple car, any one of the braking units
connected to the front wheel is activated, resulting in the turning of the temple
car in the desired direction. To bring the vehicle to a stop, both the rear and
front wheel braking units can be applied simultaneously. As a result, the effort
needed to turn the temple car and to bring it to a stop is drastically reduced.

invention.

DETAILED DESCRIPTION OF THE INVENTION
Figure 1 shows a general arrangement of the hydraulic braking system employed
in a wheel assembly of a temple car. There are two Master cylinders (1) of bore
0 36 mm provided for respective front wheel braking units (2). A second Master
cylinder (3) of bore 0 50 mm is provided for a rear wheel braking unit (4). The
bore diameter of the master cylinder (1,3) has been sufficiently increased in
order to obtain the necessary force required for applying brakes to the rear
wheels. Means (5) for fixing the master cylinder assembly (1, 3) to the axles (6 &
7) is provided. A brake rest (8) is attached to each of the axles (6, 7) to prevent
any rotary motion of the brake linings (15). A brake drum (9) is connected to the
wheel assembly. A brake lever (10) is used for applying the brakes.

Figure 2 shows the braking unit in detail. Two Brake plungers (12) are connected
to two Brake cylinders (11) containing hydraulic oil and which move back and
forth depending upon the pressure inside the cylinder (11), resulting in
expansion of an Expansion spring (13). The expansion spring (13) is in a
compressed state by default and is connected to a Brake band (14), and in turn
connected to the Brake lining (15) by means of a pivot arrangement. Thus, when
the brake level (10) is pressed the force is transmitted to the Expansion spring
(13) through the Brake plungers (12), resulting in application of brakes on the
brake drums (9).
A support unit (16) acting as a support for the Braking cylinder unit (11) is
provided. A screw rod (17) is provided with provisions for reducing the gap
between the two brake bands (14). A plurality of brake dogs (18) are locked into
the brake rest (8) in order to prevent rotary motion of the brake linings (15).

WE CLAIM :
1. A hydraulic braking system for efficient braking of temple cars, the temple
car having at least one front wheel assembly each having two wheels, and
a rear wheel assembly each joined by one axle, the hydraulic braking
system comprising:
- at least two braking units one each for each of the two front wheels;
- a combined braking unit for the rear wheel assembly;
- a first axle connecting the two front wheels of the front wheel assembly;
- a second axle operably joining the rear wheel assembly, wherein at least
one of the at least two braking units connected to the front wheel
assembly is activated for turning of the temple car to a desired direction,
and wherein all the three braking units are actuated to gradually and
smoothly stop the temple car.

2. The braking system as claimed in claim 1, wherein each of the braking
units comprises at least one master cylinder having different bore
diameters corresponding to the diameter of the front or rear wheels and
attached to the axles via a brake reset means including a fixing means to
prevent rotary motion of the brake linings connected to respective brake
plungers moving back and forth in correspondence with the pressure of
hydraulic oil containing in corresponding number of connected brake
cylinders.
3. The system as claimed in claim 1 or 2, comprising an expansion spring
being in compressed state by default, and is connected to at least one
brake band.
4. The system as claimed in claim 1 or 2, wherein a brake drum is connected
to each of the wheel assemblies, and wherein a brake lever is provided to
apply a braking force on the wheel assemblies.
5. The system as claimed in claim 1, wherein the two separate braking units
assigned to the front wheel assembly are enabled to vary the speed of the
front wheels to obtain a turning effect of the temple car.
6. The system as claimed in claim 1 or 3, wherein a force is transmitted to
the expansion spring through the brake plungers upon pressing of the
brake lever resulting in application of brakes onto the brake drums.

7. The system as claimed in claim 2, wherein the rotary motion of the brake
linings is prevented by a plurality of brake dogs provided to lock the brake
rest.
8. The system as claimed in claim 1, comprising a support unit to support
the braking cylinder units, and wherein a screw rod is provided to reduce
the gap between the brake bands.
9. The system as claimed in claim 1, wherein a single braking unit is used for
effecting braking onto both the rear wheels simultaneously.
