Furthermore, the number of the screwed hole is two, and for the screwed hole laterally to set, the hinge hole is vertical
To setting.
Furthermore, the diameter of the longitudinally connected arm is from left to right sequentially reduced, and the longitudinally connected arm is curved
Set.
The utility model beneficial effect：A kind of integral new-energy passenger chassis system knuckle arm closely processed, by being arranged on transverse direction
Arm sets at least three reinforcements with longitudinally connected arm junction, longitudinally connected arm and hinge hole section junction, will be longitudinally connected
Suffered power is distributed at reinforcement and transverse arm, hinge hole section on arm, effectively reduces stress concentration, it is strong to improve bending resistance
Degree and service life, strengthen section by winding to set on longitudinally connected arm, effectively disperseed moment of torsion, when part is damaged
Shi Jiaqiang is saved and reinforcement is first destroyed, and remainder can also continue to use, and improve service life, by setting extension spring to make
Overall structure has certain buffer capacity, anti-seismic performance is more preferable.
