Overall design of road surface irrigation sewing machine
Abstract：In this paper, theoretical analysis and calculation based on the overall
completion of the road surface irrigation sewing machine frame , leaf springs, shock
absorbers , chassis layout, installation of axles . On the scheme,structure and design
method has carried on the earnest research and choice: Using the integrated frame
arranged auxiliary beam and a bracket on it for fixing the screw hole and then
Threaded hole on beams to fix the device of heating components and the drive
motors, etc . Take the independent suspension and choose leaf spring as the elastic
element , mainly because such a suspension system is simple in structure, easy
manufacture and maintenance. And the leaf spring structure is simple , reliable , low
cost , easy maintenance. It is an elastic suspension components , but also as an
suspension guide. It connected to the frame, and moment heritability, control
wheel.At the same time, it also has the certain friction damping effect. It has many
functions. Axle sets out the sleeve, the pressure on the leaf spring plate, two U-bolts
are clamped. To make axle rotational flow, two needle roller bearing shaft is installed
on both ends. Use double shock absorber as the suspension system . Its advantage is
to adjust the resistance conveniently, simple structure, low price.
