An electronically controlled air suspension shock absorber height adjustable control device system

Abstract

The invention discloses an adjustable height control device system for an electrically controlled air suspension shock absorber, which belongs to the field of automobile accessories and comprises a shock absorber, wherein the lower end of the shock absorber is fixedly connected with a fixing rod. The electrically controlled air suspension shock absorber adjustable height control device system can adjust the height of the shock absorber by rotating a loose nut and a threaded sleeve to drive the fixing rod to move longitudinally, thereby expanding the scope of use thereof. The matching design of the rotating sleeve and the limiting ring can prevent the threaded sleeve from moving upward when rotating, thereby causing the threaded sleeve and the fixing rod to slip and fail to adjust the height. By rotating and removing the nut, the left fixing plate and the right fixing plate can be moved to both sides, thereby facilitating the removal of the left spring rubber and the right spring rubber and replacing them, thereby improving the repair and maintenance efficiency. By tightening the nut, the right fixing plate is driven to press the right rubber pad, thereby making the left spring rubber and the right spring rubber internally sealed, thereby preventing dust, impurities and sludge from entering and affecting the normal use of the shock absorber.

Description

Technical Field

[0001] The invention relates to the field of automobile accessories, and more particularly to a height-adjustable control device system for an electronically controlled air suspension shock absorber. Background Art

[0002] Suspension shock absorbers are installed in parallel with elastic elements in the suspension system to improve the ride smoothness of the car. Shock absorbers are installed in parallel with elastic elements in the suspension to attenuate vibrations. Shock absorbers used in automobile suspension systems are mostly hydraulic shock absorbers. Their working principle is that when the frame (or body) and the axle are vibrated and there is relative movement, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly flows from one cavity into another through different pores.

[0003] The existing electronically controlled air suspension shock absorber height adjustable control device system has a fixed telescopic range of the shock absorber and cannot be adjusted in height. It is only suitable for fixed models of cars and has a limited scope of use. At the same time, the maintenance, replacement and disassembly of the spring rubber protective cover of the shock absorber requires the shock absorber to be removed first, and the connection structure between the spring rubber protective cover and the shock absorber to be removed before it can be removed from the upper end of the telescopic rod, which is inconvenient for the maintenance and replacement of the spring rubber protective cover. Therefore, it is necessary to improve the existing technology. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide an electronically controlled air suspension shock absorber height adjustable control device system, which can adjust the height of the shock absorber and expand its scope of use by turning the loose nut, rotating the threaded sleeve, and driving the fixed rod to move longitudinally. The matching design of the rotating sleeve and the limit ring can prevent the threaded sleeve from moving upward when rotating, causing the threaded sleeve and the fixed rod to slip and unable to adjust the height; by turning to remove the nut, the left and right fixed plates can be moved to both sides, which is convenient for removing the left and right spring rubbers and replacing them, thereby improving the maintenance efficiency; by tightening the nut, the right fixed plate is driven to press the right rubber pad, so that the left and right spring rubbers are internally sealed to prevent dust, impurities and silt from entering and affecting the normal use of the shock absorber.
