Sliding column aluminium alloy spring lower tray structure

Abstract

The invention relates to a sliding column aluminium alloy spring lower tray structure and belongs to the technical field of automobile design and manufacture. The sliding column aluminium alloy springlower tray structure comprises a columnar cylinder, wherein a circular spring lower end ring mounting plate is arranged on the upper end face of the columnar cylinder; a conical circular truncated cone structure is formed on the inner circumferential side of the circular spring lower end ring mounting plate; a central hole is processed from the conical circular truncated cone structure to the columnar cylinder; a notch structure is formed in one side of each of the conical circular truncated cone structure, the circular spring lower end ring mounting plate and the columnar cylinder; a first tightening arm and a second tightening arm are oppositely arranged on the columnar cylinder outer circumferential walls on the two sides of the notch structure; and the normal direction of the circularspring lower end ring mounting plate inclines by certain angle relative to the axial direction of the central hole. The sliding column aluminium alloy spring lower tray structure can use light material, is large in structural stiffness and higher in integration level and is movably connected with an absorber cylinder barrel to realize the effects of free of welding, reducing weight, being convenient to repair and adjust and reducing the using cost.

Description

technical field [0001] The invention relates to the technical field of automobile design and manufacture, and more specifically, the invention relates to an aluminum alloy spring unsprung tray structure of a sliding column. Background technique [0002] Such as figure 1 As shown, in the prior art, the lower tray structure of the sliding column spring is usually formed by stamping a single steel plate, and the connecting rod bracket of the stabilizer bar is also a stamped structure of thick steel plate. The two are independent, and both are welded to the shock absorber cylinder. The pallet structure under the strut spring in the prior art has the following technical problems: 1) they are all welded to the cylinder, which is prone to welding defects and affects the strength of the cylinder; 2) each is independent, requiring welding and positioning respectively, and the overall accuracy is poor; 3) In order to ensure the overall rigidity of the pallet, a large plate thickness ...

Problems solved by technology

The pallet structure under the strut spring in the prior art has the following technical problems: 1) they are all welded to the cylinder, which is prone to welding defects and affects the strength of the cylinder; 2) each is independent, requiring welding and positioning respectively, and the overall accuracy is poor; 3) In order to ensure the overall rigidity of the pallet, a large plate thickness is often required, which makes it difficult to reduce weight; 4) The shock absorber is a vulnerable part. Once it fails, it needs to be replaced as a whole, which increases the cost of use for customers
