With the technical scheme, the air spring has ideal nonlinear elasticity characteristic, the height of the spring can be designed to be lower, the structure has long service life and light weight, the bearing capacity of the trailing arm torsion beam is strong, the quality is reliable and stable, left and right wheels are provided with larger space for positioning, the camber of the wheel is steady, bending stress deformation of a damper is avoided, and the stability and the comfort of the automobile are improved.
Description
Technical field
The utility model relates to a kind of rear overhang shelf structure.
Background technology
At present, general manned vehicle, what the rear suspension structure was used is coil spring, but it is limited by carload level rigidity of helical spring, and bodywork height changes along with the variation of carload,
Coil spring can only keep linear rigidity within the specific limits, and the bigger coil spring of rigidity is installed, so that wheel is keeping the tendency that contact with the road surface, improves the ground ability of grabbing of tire, and still such drawback is that the stronger sensation of jolting is arranged when riding in an automobile; And adopt softer coil spring, to adapt to rugged road surface, improve stationarity and traveling comfort when riding in an automobile, but such manoeuvereability of automobile is relatively poor.Use helical spring suspension and belong to the passive type suspension, aspect a lot of, very big limitation is arranged.
The utility model content
Problem to be solved in the utility model provides a kind of rear overhang shelf structure, and its purpose improves automobile balance and traveling comfort.
To achieve these goals, the technical scheme taked of the utility model is:
A kind of rear overhang shelf structure provided by the utility model, comprise longeron, crossbeam, torsion beam support and torsion beam trailing arm, described torsion beam support is connected with axis body after the torsion beam by bolt, on described torsion beam trailing arm and torsion beam crossbeam, be provided with pallet under the air bellow, air bellow is fixedly mounted under the described air bellow on the pallet, at described air bellow top the air bellow top tray is installed.
Pallet and torsion beam trailing arm are welded to connect under the described air bellow.
On pallet under the described air bellow, be installed with and connect support on the air bellow.
Connection support and torsion beam crossbeam are welded to connect on the described air bellow.
Adopt technique scheme, air bellow has desirable nonlinear elasticity feature, the spring height is programmable lower, long service life, light weight, the load-carrying capacity of trailing arm torsion beam is strong, and reliable in quality is stable, can make left and right wheels have bigger space orientation, camber angle is stablized constant, has avoided the bumper stress deformation that bends, and has improved the stationarity and the traveling comfort of automobile.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this specification sheets and the mark among the figure are made brief description:
Fig. 1 is a structural representation of the present utility model.
Be labeled as among the figure:
1, longeron, 2, crossbeam, 3, the torsion beam support, 4, pallet under the air bellow; 5, torsion beam trailing arm, 6, air bellow, 7, connect support on the air bellow, 8, the air bellow top tray.
The specific embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and principle of work, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
In order to solve the problem that exists at the described present known technology of this specification sheets background technology part and to overcome its defective, improve automobile balance and traveling comfort.The technical scheme that the utility model is taked is:
As shown in Figure 1, this rear overhang shelf structure provided by the utility model, comprise longeron 1, crossbeam 2, torsion beam support 3 and torsion beam trailing arm 5, described torsion beam support 3 is connected with axis body after the torsion beam by bolt, on described torsion beam trailing arm 5 and torsion beam crossbeam, be provided with pallet 4 under the air bellow, air bellow 6 is fixedly mounted under the described air bellow on the pallet 4, at described air bellow top air bellow top tray 8 is installed.
Adopt technique scheme, air bellow 6 is to charge into pressurized air in a leak free container, utilizes gas compressibility to realize its elastic reaction.Air bellow 6 has comparatively ideal nonlinear elasticity characteristic, and the spring height is programmable lower, and long service life, light weight have improved the stationarity and the traveling comfort of automobile.
The load-carrying capacity of trailing arm torsion beam is strong, and reliable in quality is stable, can make left and right wheels have bigger space orientation, and camber angle is stablized constant, has avoided the bumper stress deformation that bends, and has improved the stationarity and the traveling comfort of automobile.
As shown in Figure 1, pallet 4 is welded to connect with torsion beam trailing arm 5 under the described air bellow.
On pallet 4 under the described air bellow, be installed with and connect support 7 on the air bellow.
Connecting support 7 on the described air bellow is welded to connect with the torsion beam crossbeam.
Adopt technique scheme, the advantage of trailing arm torsion beam is that load-carrying capacity is strong, and quality is reliable and stable relatively, can make left and right sides two-wheeled have bigger space orientation, and camber angle is stablized constant, has avoided the bumper stress deformation that bends, and has guaranteed comfort level.
The technical scheme that the utility model adopted compared with prior art, has tangible difference, possessed substantial characteristics, and obtained progress technically, be worth in industrial promotion and application, so, the utlity model has novelty, creativeness and practicality.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
