FIELD
The present disclosure relates to steering oil filling systems.
BACKGROUND
The background information herein below relates to the present disclosure but is
not necessarily prior art.
Conventionally, at the time of filling steering oil in a steering sub-assembly, the
operator is required to manually inspect the quantity of oil being filled in the
steering sub-assembly. This conventional approach however, requires the operator
to ascertain the quantity of oil filled in the steering sub-assembly based on their
instincts. When operator assumes the quantity of oil filled in the steering subassembly
is adequate, he/she stops filling oil and transfers the steering subassembly
to the storage line. This often leads to inadequate oil being filled within
the steering sub-assembly which in turn results in hard steering or malfunctioned
steering system, which is not desirable.
There is, therefore, felt a need to provide a safe steering oil filling system and a
method thereof that eliminates the above-mentioned drawback(s).
OBJECTS
Some of the objects of the present disclosure, which at least one embodiment
herein satisfies, are as follows:
It is an object of the present disclosure to ameliorate one or more problems of the
prior art or to at least provide a useful alternative.
It is an object of the present disclosure to provide a steering oil filling system and
a method thereof.
Another object of the present disclosure is to provide a system and method for
filling oil in a steering sub-assembly that eliminates human error.
Still another object of the present disclosure is to provide a system and method
that ensures filling of adequate steering oil in a steering sub-assembly.
Yet another object of the present disclosure is to provide a system and method that
prevents the partially oil filled steering sub-assemblies to proceed towards next
workstation/storage line.
Still another object of the present disclosure is to provide a system and method for
filling oil in a steering sub-assembly that is reliable.
Other objects and advantages of the present disclosure will be more apparent from
the following description, which is not intended to limit the scope of the present
disclosure.
