Auto leaf spring leaf spring processing techniques during disassembly and assembly should pay attention to what? When install the plate spring in car suspension and timing of its under vertical load, deformation of every plate spring under the action of force, and tend to be upward arch. At this point, the axis and frame close to each other. When the axle and frame away from each other, the leaf spring is vertical load and the deformation will gradually decrease, sometimes even reverse. Master rolls of film ear force is very big, this is a weakness. In order to improve the primary membrane stress of the ear, often will bend the end of the second film roll ear and wrapped around the main roller ear. Auto leaf spring leaf spring processing techniques during disassembly and assembly should pay attention to what? When install the plate spring in car suspension and timing of its under vertical load, deformation of every plate spring under the action of force, and tend to be upward arch. At this point, the axis and frame close to each other. When the axle and frame away from each other, the leaf spring is vertical load and the deformation will gradually decrease, sometimes even reverse. Master rolls of film ear force is very big, this is a weakness. In order to improve the primary membrane stress of the ear, often will bend the end of the second film roll ear and wrapped around the main roller ear. Car plate spring set installed by the hydraulic pipeline, hydraulic cylinder, piston rod, bolts, loading platform, slide, gantry, base, supporting frame, baffle, the base 2, discharging switch, load switch, screws, hydraulic station, its characteristic is the base of a set upper gantry, gantry top center through the bolt set the hydraulic cylinder, the lower end of the gantry center location set loading machine, loading machine in the middle of the setting load and unload switch, loading of bilateral symmetry set support frame, the upper end fixed connection slide end of the support frame, on the other side of the slide set baffle, the utility model beneficial effect is to adopt hydraulic transmission, small motion inertia, fast response, easy to control, staff can work to continuous auto leaf spring assembly, improve work efficiency, reduce the work intensity of the workers. Leaf spring in the disassembly and assembly should pay attention to what? ( 1) When leaf spring assembly surface rust should be shaved, among each piece coated graphite calcium base grease. This grease can guarantee each piece of leaf spring between the smooth, increase the pressure resistance. ( 2) If the steel plate spring center bolt fracture, need to process the center bolt, then its diameter should not less than 1 steel plate center hole diameter. 5mm。 If the smaller the diameter of the center bolt, the cut may be copy of steel plate spring. ( 3) If loose steel clamp fixed rivet, should be to good riveting, the width of the clamp should be appropriate, and steel plate on both sides should be 0. 7 ~ 1. 0 mm clearance. Clamp sleeve and top of the leaf spring distance should be 1 ~ 2 mm, to ensure the freedom of leaf spring done. Currently many factories producing steel clamp has remove the casing to welding, the roof and the steel plate surface distance is also known for 1 ~ 2 mm. ( 4) Between, after each leaf spring assembly are closely linked, allows the adjacent two pieces is not more than a quarter of the total contact length, that is not greater than 1. 5 mm gap. If total small contact length, leaf spring leaf is in danger of broken. ( 5) Leaf spring before loading, the steel plate of the first and second volume of ear and steel stents fit clearance shall not be less than 1 mm, clearance is too large to add the washer to adjust. Clearance is too large, the side impact runout, steel plate ear place is easy to be broken. ( 6) Leaf spring of U bolt should be evenly cross and torque tighten by the regulation, after fastening bolts should reveal thread above 3 button, if you don't show nut screw, nut to have the possibility of slide fastener.
