Longitudinal force, but simultaneously also more save suspension arrangement space, reduce rod piece, it is cost-effective.
The operation principle of the utility model is as follows：
1. constraining wheel movement：Suspension frame structure constrain wheel movement, in vehicle travel process wheel rotation generate forward
Power, but for the degree of freedom in 6 directions of wheel itself, the target of entire mechanism is that a permission wheel carries out on the directions z
Translation, because the actual effect of mechanism reason (buffer units such as bushing rubber) wheel movement will produce the directions x, on the directions y it is light
To translation, the utility model suspension frame structure is played by the connection of the tie point and leaf spring 5 of 2 upper end of damper by micro- translation and z
The directions limiting wheel y translate and around two degree of freedom that the directions x rotate, and limitation vehicle is played by the connection of prenex control arm 3
The one degree of freedom rotated around the directions z is taken turns, is connect with knuckle 8 by damper 2, leaf spring 5 and prenex control arm 3 and plays limitation
Around the directions y rotate and the directions x on translation two degree of freedom, last entire mechanism allows wheel to carry out the translation in the directions z.
2. providing buffering and damping：Suspension frame structure can alleviate ground shock and reduce vibrations, in vehicle travel process, when
When wheel encounters impact (similar stone or uneven road surface), impact force is absorbed by leaf spring 5 and is deformed upon, wheel is made to occur up and down
Bounce is then deformed by the damping rubber block intervention absorption impact force on damper 2 when impact force is excessive, makes big portion with this
Point impact energy can not be transmitted to vehicle body, have the function that alleviate ground shock.And after leaf spring 5 deforms upon, impact knot
Beam, because deformation acts the reason of power, leaf spring 5 is sprung back, and slows down the rebound velocity of leaf spring 5 by damper 2, reaches outstanding
Frame compression springs back slow effect soon, plays the role of reducing vibrations.
3. providing support force：Suspension frame structure connects wheel and vehicle body, transmits ground supports power, keeps vehicle body hanging.Vehicle body by
Decline in its own gravity reason, which forms vertical load and be transmitted on leaf spring 5 by leaf spring fixing bracket 4, and leaf spring 5 is made
The reaction force for balancing the vertical active force enough is generated after a certain amount of deformation occurs for elastic element, and because entirely hanging
Frame structure ensure wheel can only occur z to translational motion, so ensure vehicle body lateral stability, so that vehicle body is balanced outstanding
It is empty.
The above-mentioned description to embodiment is that this practicality can be understood and applied for ease of those skilled in the art
It is novel.Person skilled in the art obviously easily can make various modifications to above-described embodiment, and illustrating herein
General Principle be applied in other embodiment without having to go through creative labor.Therefore, the utility model is not limited to above-mentioned
Embodiment, those skilled in the art's announcement according to the present utility model, the improvement made for the utility model and modification are all answered
This is within the protection scope of the utility model.
