Abstract
The utility model provides a vehicle suspension subassembly, relates to vehicle passive suspension field. Adopt the two -stage cascaded structure, first attenuator and the parallelly connected primary structure that forms of first spring promptly, again with by second attenuator, second spring, be used to the parallelly connected secondary structure who forms of container and establish ties together, this cascaded structure is located between the swing arm of being connected with body connection's rocking arm with the sub vehicle frame, this structural design has effectively restrained automobile body resonance, has improved the low frequency frequency response characteristic of vehicle, the ride performance of vehicle is being shown to be promoted.
Description
Technical field
The utility model relates to the passive suspension field of vehicle, particularly a kind of vehicle suspension component.
Background technology
Suspension system is an important component part in vehicle driving system, and the travelling comfort of quality to vehicle of suspension system has a significant impact.Used container is a two-end-point element, and it is in parallel with it that damper can stride across used container, thus absorbs its vibrational energy, makes the passive realization of desirable skyhook damping become possibility.In recent years, used container is used in vehicle suspension system, steering swivel system and building vibrating isolation system, and research shows that used container can improve the anti-vibration performance of various mechanical vibration network.Researchist adopts diverse ways optimization to be used to container suspension frame structure and parameter.But up to now, theory and simulation study are also only limitted to the research of passive skyhook damping suspension.
Summary of the invention
The utility model proposes a kind of vehicle suspension component, solve sympathetic body oscillation in vehicle travel process, produce low frequency frequency response, cause the problem of the uneven compliance of the traveling of vehicle, its structure is simple, reasonable in design, easy to maintenance.
The technical scheme that the utility model adopts is: a kind of vehicle suspension component, said modules is assembled between vehicle body and subframe, its technical essential is: the first damper is in parallel with the first spring forms primary structure, be cascaded again with by the second damper, the second spring, the used container secondary structure formed in parallel, this cascaded structure is between the rocking arm be connected with vehicle body and the swing arm be connected with subframe.
One end connecting rocker arm after first damper is in parallel with the first spring, the other end connects swing arm; One end connecting rocker arm after second damper, the second spring, used container parallel connection, other end auxiliary connection vehicle frame.
Described rocking arm is bascule structure.
Advantage of the present utility model and beneficial effect are: this vehicle suspension component, adopt two-stage series connection structure, namely the first damper is in parallel with the first spring forms primary structure, be cascaded again with by the second damper, the second spring, the used container secondary structure formed in parallel, this cascaded structure is between the rocking arm be connected with vehicle body and the swing arm be connected with subframe, this structure design effectively inhibits sympathetic body oscillation, improve the low frequency Frequency Response of vehicle, the riding comfort of vehicle is significantly improved.
Accompanying drawing explanation
Be further described in detail originally executing mode below in conjunction with accompanying drawing.
Fig. 1 is vehicle suspension component structural representation of the present utility model;
In figure, sequence number is described as follows: 1 first spring, 2 first dampers, 3 second dampers, 4 second springs, 5 used containers, 6 vehicle bodies, 7 subframes, 8 rocking arms, 9 swing arms.
Detailed description of the invention
Below in conjunction with accompanying drawing 1 and detailed description of the invention, the utility model is elaborated, below describe only exemplarily and
Explain, any pro forma restriction is not done to the utility model.
Vehicle suspension component in the present embodiment, said modules is assembled between vehicle body 6 and subframe 7, first damper 2 is in parallel with the first spring 1 forms primary structure, be cascaded again with by the second damper 3, second spring 4, used container 5 secondary structure formed in parallel, this cascaded structure is between the rocking arm 8 be connected with vehicle body 6 and the swing arm 9 be connected with subframe 7.
Wherein, one end connecting rocker arm 8 after the first damper 2 is in parallel with the first spring 1, the other end connects swing arm 9; One end connecting rocker arm 8 after second damper 3, second spring 4, used container 5 parallel connection, other end auxiliary connection vehicle frame 7.Spring in the present embodiment adopts spiral spring, and its number of active coils is 8 circles, and steel wire diameter is 11mm, and pitch is 34mm.Used container 5 adopts the rotary ball-screw of leading screw to be used to container, and the specifications and models of ball screw assembly, are: FF2D2005R-3-P5.
Rocking arm 8 is bascule structure.Rocking arm in the present embodiment only changes the direction of suspension application force, and does not change the size of application force.When real vehicle is installed, lever pivot angle is smaller, is similar to linear system.
Vehicle suspension component in the present embodiment is compared with the passive spring suspension vehicle of tradition, and the left back vehicle body acceleration gain resonance peak of passive skyhook damping spring suspension vehicle have dropped 34% in 0.9 ~ 2.8 frequency limit, also has and decline a little within the scope of 2.8 ~ 8Hz.Within the scope of 1.9 ~ 3Hz, rear left wheel acceleration responsive does not obviously worsen.Visible, passive skyhook damping suspension effectively inhibits sympathetic body oscillation, and improve the low frequency Frequency Response of vehicle, the riding comfort of vehicle is significantly improved.
Although the foregoing describe detailed description of the invention of the present utility model, but the those skilled in the art in this area are to be understood that, these are only casehistorys, can make various changes or modifications, and do not deviate from principle of the present utility model and essence to these embodiments.Scope of the present utility model is only defined by the appended claims.
Claims (3)
1. a vehicle suspension component, said modules is assembled between vehicle body and subframe, it is characterized in that: the first damper is in parallel with the first spring forms primary structure, be cascaded again with by the second damper, the second spring, the used container secondary structure formed in parallel, this cascaded structure is between the rocking arm be connected with vehicle body and the swing arm be connected with subframe.
