Front axle bending, torsion deformation and its influence

Front axle deformation performance in the following six aspects: ( 1) Left and right steel plate spring seat plane ( Machining datum) Bending deformation in front axle vertical plane ( Up and down) 。 ( 2) Left and right steel plate spring seat plane bending deformation in front axle horizontal plane ( Before and after) 。 ( 3) Left and right steel plate spring seat plane around the front axle axis torsion deformation ( Crooked. ( 4) King pin hole centerline bending deformation in front axle vertical plane. ( 5) King pin hole centerline in front axle horizontal plane bending deformation. ( 6) King pin hole centerline around the front axle axis torsion deformation. Front axle bending and torsion deformation, change the orientation Angle of the king pin and the front wheel, destruction of the front wheel assembly location, each other directly influence the steering performance and cause the acceleration of the tire wear, make the car run in partial, cause driving towards difficulties and unsafe.
