AI Technical Summary
When the tractor bracket is connected to the engine, shear stress concentration at the connection position causes cracking or breakage, and the existing structural strength is insufficient.
A bracket mounting support is designed, including a first and a second mounting plate. The bracket is fixed to the first mounting plate through a bracket connecting hole, and the engine is fixed to the second mounting plate through an engine connecting hole. The connection method is changed to a front-to-back setting, which increases the structural strength, and the structural strength is strengthened by reinforcing ribs.
The shear moment is reduced, stress concentration is relieved, and the reliability and structural strength of the bracket installation are improved.
