Abstract
The utility model provides a sub vehicle frame and body connection's buffering damping device, including flange face bolt, flange face nut, metallic gasket, rubber pad and metal spring, the flange face bolt from bottom to top passes sub vehicle frame and automobile body panel beating in proper order, and the rubber pad design is the hollow circular cylinder form, and metal spring is located the hollow inner circle of rubber pad, and a set of metallic gasket, rubber pad and metal spring are established to automobile body panel beating each symmetry cover from top to bottom. The utility model discloses can the effective filtration chassis to transmit the vibration for the automobile body, especially centering high -frequency vibration filter effect obvious. Help avoiding the resonant problem of partial automobile body part in addition.
Description
Technical field
This utility model relates to the damping device that a kind of subframe is connected with vehicle body.
Background technology
At present, vehicle chassis subframe is connected as master with connecting of vehicle body with the bolt of rigidity, this connection is owing to being metal and the coordinating of metal, therefore can cause vibration that vehicle produces in the process of moving through subframe relatively more pass to vehicle body, cause body vibrations, noise, reduce ride comfort sex chromosome mosaicism.
Present stage, use and flexibly connect between some chassis and vehicle body, i.e. the connecting portion at subframe with vehicle body adds elastic vibration isolation pad, although so can offset part vibration and noise that vehicle produces in the process of moving, but effect is not the most preferable.
Summary of the invention
The purpose of this utility model is exactly for the purpose of improving vehicle riding comfort, and a kind of damping device of design, this device can effectively filter the vibration passing to vehicle body in vehicle travel process.
Technical solutions of the utility model are: provide the damping device that a kind of subframe is connected with vehicle body, including flange face bolt, flange surface nut, metallic gasket, rubber blanket and metal spring, flange face bolt from bottom to top sequentially passes through subframe and vehicle body sheet metal, rubber blanket is designed as hollow cylindrical, metal spring is positioned at the inner ring of rubber blanket hollow, the most sheathed metallic gasket of flange face bolt key between flange surface nut and vehicle body sheet metal, rubber blanket and metal spring, the sheathed one group of metallic gasket of the most each symmetry of vehicle body sheet metal, rubber blanket and metal spring.
Preferably, a bottom surface of described rubber blanket has groove and fillet surface.
Advantage of the present utility model is:
1, rubber blanket is arranged at the Dual-layer of vehicle body sheet metal with the combination of metal spring, both can support with relative resilient, it is thus possible to the vibration to both direction back and forth and relevant multiple degree of freedom buffers, improve damping performance, effectively can pass to the vibration of vehicle body by water filtration chassis, especially centering dither filter effect is obvious.Additionally help the problem avoiding part car body component to resonate.
2, metal spring is due to material behavior, has more more preferable dynamic response performance than rubber blanket, and is provided that non-yielding prop when contraction reaches capacity, thus avoids the excess impact damage of rubber blanket.
3, screw bolt and nut uses flange face bolt and flange surface nut, can be used to share the pressure of contact surface.
4, the pressure that metallic gasket can make rubber blanket bear is uniformly distributed, thus produces preferable elastic effect, it is to avoid shear stress, it is ensured that the life-span of rubber blanket.
5, a bottom surface of rubber blanket has groove and fillet surface, is possible to prevent the excessive deformation of rubber blanket in installation process, improves the fatigue resistance of rubber blanket.

Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further, as shown in Figure 1, this utility model is the damping device that a kind of subframe is connected with vehicle body, including flange face bolt (1), flange surface nut (2), metallic gasket (3), rubber blanket (4) and metal spring (5), flange face bolt (1) from bottom to top sequentially passes through subframe (7) and vehicle body sheet metal (6), rubber blanket (4) is hollow cylindrical, metal spring (5) is positioned at the inner ring of rubber blanket (4) hollow, both matched combined are together, relative resilient supports；The most sheathed metallic gasket of flange face bolt (1) key (3), rubber blanket (4) and metal spring (5) between described flange surface nut (2) and vehicle body sheet metal (6), the sheathed one group of metallic gasket (3) of described vehicle body sheet metal (6) the most each symmetry, rubber blanket (4) and metal spring (5).
As in figure 2 it is shown, a bottom surface of described rubber blanket (4) has groove (9) and fillet surface (8).In installation process, rubber blanket stress can cause the effect of deformation, groove and fillet surface to be to prevent rubber blanket excessive deformation, improves the fatigue resistance of rubber blanket.
The foregoing is only preferred implementation of the present utility model, it is noted that for the person of ordinary skill of the art, on the premise of creating design without departing from this utility model, it is also possible to make deformation and improve, all should belong to protection domain of the present utility model.
Claims (2)
1. the damping device that a subframe is connected with vehicle body, including flange face bolt (1), flange surface nut (2), metallic gasket (3), rubber blanket (4) and metal spring (5), described flange face bolt (1) from bottom to top sequentially passes through subframe (7) and vehicle body sheet metal (6), it is characterized in that: described rubber blanket (4) is hollow cylindrical, described metal spring (5) is positioned at the inner ring of rubber blanket (4) hollow, the most sheathed metallic gasket of flange face bolt (1) key (3) between described flange surface nut (2) and vehicle body sheet metal (6), rubber blanket (4) and metal spring (5), the sheathed one group of metallic gasket (3) of described vehicle body sheet metal (6) the most each symmetry, rubber blanket (4) and metal spring (5).
The damping device that subframe the most according to claim 1 is connected with vehicle body, it is characterised in that: a bottom surface of described rubber blanket (4) has groove (9) and fillet surface (8).
