Embodiment Construction
[0029] The application will be described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific embodiments are only used to further illustrate the application, and cannot be interpreted as limiting the protection scope of the application. The above application content makes some non-essential improvements and adjustments to this application.
[0030] combine Figure 1 to Figure 6 As shown, the axial hydraulic bushing of the subframe includes a glued part 1 , a throttle plate 2 , a diaphragm 3 , a riveting plate 4 and a limit block 5 .
[0031] The glued part 1 is composed of an inner metal frame 11, an outer metal frame 12, a rubber body 13 and a rivet plate 14. The inner metal frame 11 is located inside the outer metal frame 12, and the rivet plate 14 is located at the shaft end of the outer metal frame 12. The rubber body 13 is formed between the metal frame 11 and the outer metal frame 12 and between...

The invention discloses an auxiliary frame axial hydraulic lining. The auxiliary frame axial hydraulic lining comprises a gluing piece, a throttling disc, a diaphragm, a riveting pressing plate and alimiting block; the gluing piece is composed of an inner metal framework, an outer metal framework, a rubber body and a rotary riveting plate; the throttling disc, the diaphragm and the riveting pressing plate are sequentially arranged on one shaft end face of the rotating riveting plate in the gluing piece, the diaphragm and the internally-sunken rubber body form a closed liquid cavity, the throttling disc divides the liquid cavity into an upper liquid chamber and a lower liquid chamber, and a plurality of axial throttling holes are formed in the throttling disc; the limiting block is arranged on the other shaft end face of the gluing piece, and the limiting block is in contact connection with the rubber body between the inner metal framework and the outer metal framework. The auxiliary frame axial hydraulic lining has the advantages that an axial damping structure is adopted, the throttling holes are connected with the two liquid chambers, so that axial liquid resistance resonance isrealized; the dynamic damping can be changed through the size and the number of the throttling holes; the auxiliary frame axial hydraulic lining is simple in structure, low in cost and convenient inmanufacturing, and has excellent vibration reduction and isolation performance and durability under various working condition requirements, so that the comfort requirement of a whole vehicle is met, and the reliability durability is improved.
Description
technical field [0001] The invention relates to the technical field of vehicle suspension technology, in particular to an axial hydraulic bushing of a sub-frame. Background technique [0002] Generally, in the case of improving road noise, brake vibration, roaring vibration, etc., it is necessary to select the bushing to input high damping at a certain frequency. Due to the characteristics of the rubber itself, it is difficult for the general rubber bushing to provide the large damping required for low-frequency control. The damping can be slightly improved by adjusting the rubber formula, but the bushing has poor fatigue and creep properties and cannot be used in automobiles. Under the action of external excitation, the rubber deformation of the hydraulic bushing causes the volume of the two liquid chambers to be different. At the same time, the liquid in the hydraulic bushing is incompressible, which causes the liquid to pass through the flow channel to generate damping to...
