Background
The automobile steel plate spring is an elastic element which is most widely applied in automobile suspensions, and is an elastic beam which is approximately equal in strength and formed by combining a plurality of alloy spring pieces which are equal in width but unequal in length (the thicknesses can be equal or unequal), and two ends of the elastic beam naturally bend upwards after the elastic beam is installed. When the impact force of the road surface to the wheels is transmitted, the steel plate deforms to play the roles of buffering and vibration reduction, and the steel plate also has the function of guiding transmission when being longitudinally arranged. The automobile steel plate spring rear lifting lug has the main function of bearing the steel plate spring, and is connected with a crossbeam of a vehicle body ground plate and then the steel plate spring (commonly called a bridge) is hung on the crossbeam to realize the bearing function. Therefore, the assembly of the rear shackle assembly of an automotive leaf spring is of paramount importance, however, the prior art has the following drawbacks and disadvantages with respect to the shackle assembly:
the mounting point of the rear point of the automobile steel plate spring is not arranged on the frame, and is welded on a circular tube on the frame, and the mounting point is wider than the frame. The traditional lifting lug assembly has small installation space and is difficult to assemble, and the production beat is seriously influenced. Referring to fig. 1, in the assembly scheme of the lifting lug assembly in the prior art, the distance between a frame 3 and a frame mounting bracket 4 is only less than 50mm, and after the lifting lug assembly is assembled, because the distance between a lifting lug inner side plate and the frame is too small, a worker can block the sight by hand when mounting a nut, and the worker can only screw the nut in the vertical direction by hand, so that the assembly is difficult, and the production cycle is influenced. When the air gun is used for tightening the lower bolt and applying torque, the air gun and the torque wrench interfere with the lower plane of the frame 3.
