ABSTRACT:
FIELD TO WHICH THE INVENTION RELATES
This invention relates to a brake reaction pin utilized in a combination axle support and brake mechanism.
BACKGROUND OF THE INVENTION
Brake shafts have been utilized to control power from a positive mechanism (such as a motor) to a negative mechanism (such as a brake, pump, or retarder). In some instances, the same shaft has been utilized for a secondary purpose, such as functioning as an axle for a wheel or a rotary support for a secondary member (such as a winch spool). A number of these devices utilize interleaved disk brakes, typically with a substantially triangular spline to spline interconnection to their respective members, shaft, or housing. This spline interconnection typically requires machining or some other additional operation to form the splines. In addition, the tolerances of the splines allow for a measure of movement of the shaft in respect to the housing when the brake is engaged.
One application for brake shafts is as a combined axle and brake mechanism for scissorlifts. An example of this is the hydraulically released spring applied brake mechanism of Genie Industries of Redmond, Wash. However, the cost of this particular unit is sufficiently high that most manufactures of scissorlifts use live axles with separate drum brake mechanisms taken from a small automobile instead. These axle assemblies take hours of time to assemble and install. Others use a split-axle in the back, with the brakes being either thereon or on the motor drive systems of the front wheels.
SUMMARY OF THE INVENTION
It is an object of this invention to allow for a multiple use brake reaction pin.
It is an object of this invention to reduce the cost of brakes.
It is an object of this invention to increase the strength of brakes.
It is an object of this invention to manufacture higher quality brakes.
It is an object of this invention to lower the tolerances in brakes.
It is a further object of this invention to increase the speed of manufacture of brakes. other objects and a more complete understanding of the invention may be had by referring to the drawing in which:
