Abstract
The utility model discloses a car sub vehicle frame connection structure assembly, including frame, sub vehicle frame with be used for the U type connecting piece of sub vehicle frame with connected to the frame, the sub vehicle frame is including last casing, with the lower casing of epitheca body coupling with set up at last casing and two stay tubes between the casing down, and two landing legs of U type connecting piece pass in a stay tube respectively that the end fastens, sub vehicle frame is formed by upper and lower casing fixed connection, and the stay tube that sets up between upper and lower casing not only can improve the overall structure intensity of sub vehicle frame, moreover through the cooperation with U type connecting piece, has strengthened the joint strength behind sub vehicle frame and the connected to the frame greatly to guarantee sub vehicle frame and connected to the frame's the stability and the security of whole car.
Description
Technical field
This utility model relates to automobile chassis field, particularly to a kind of auxiliary frame connecting structure of vehicle assembly.
Background technology
Subframe is as load bearing component important on automobile, support the multiple parts connecting automobile, the critical component such as including steering mechanism, power assembly, stabiliser bar assembly, the safety of car load and the performance of car load are played vital effect by its fatigue life, dimensional accuracy, subframe and vehicle body click on luggage by four installations and join, so the coupling of the design and vehicle body installing point seems most important.Existing subframe mostly is with the connected mode of vehicle body and is directly connected with vehicle body with bolt, the intensity of junction point place subframe self it cannot be guaranteed that, and the vehicle frame after bolt connects and the bonding strength between subframe cannot guarantee that.
Accordingly, it would be desirable to existing sub-frame connecting structure is improved, ensureing on the basis of structural strength of junction point place subframe self, can ensure simultaneously subframe be connected with vehicle frame after bonding strength.
Utility model content
In view of this, this utility model provides a kind of auxiliary frame connecting structure of vehicle assembly, can ensure on the basis of structural strength of junction point place subframe self, can ensure simultaneously subframe be connected with vehicle frame after bonding strength.
Auxiliary frame connecting structure of vehicle assembly of the present utility model, including vehicle frame, subframe and the U-shaped connector for subframe is connected with vehicle frame, subframe includes the lower house that upper shell is connected and two stay tubes being arranged between upper shell and lower house with upper shell, and two supporting legs of U-shaped connector fasten through also end respectively in a stay tube.
Further, the inner side of upper shell is or/and the inner side of lower house is formed for a location convex for stay tube location.
Further, between vehicle frame and subframe, compression is provided with at least one of which vibration isolator.
Further, the location convex of the end and corresponding position of propping up stay tube forms cone match.
Further, each supporting leg of frame inside correspondence U-shaped connector is provided with a reinforcement convex for strengthening coupling stiffness, strengthens being provided with the via for supporting leg traverse on convex.
The beneficial effects of the utility model: auxiliary frame connecting structure of vehicle assembly of the present utility model, subframe is formed by fixedly connecting by upper and lower casing, the stay tube arranged between upper and lower casing not only can improve the overall construction intensity of subframe, and by with the coordinating of U-shaped connector, greatly strengthen the bonding strength after subframe is connected with vehicle frame, thus ensureing the safety of stability that subframe is connected and car load with vehicle frame.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further described.
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Fig. 1 is this utility model structural representation, as shown in the figure: the auxiliary frame connecting structure of vehicle assembly of the present embodiment, including vehicle frame 1, subframe and the U-shaped connector 2 for subframe is connected with vehicle frame 1, subframe includes the lower house 4 that upper shell 3 is connected and two stay tubes (as shown be a stay tube 5 and prop up stay tube 5a) being arranged between upper shell 3 and lower house 4 with upper shell 3, and two supporting leg 2-1 of U-shaped connector 2 fasten through also end respectively in a stay tube (as shown be and prop up stay tube 5 and a stay tube 5a)；Fixing connection between the upper shell 3 of subframe and lower house 4, can pass through to weld or the realization of other existing machinery connected modes, two stay tubes are arranged between upper shell 3 and lower house 4, prop up the top and bottom one_to_one corresponding of stay tube to terminating in upper shell 3 and lower house 4, the upper shell 3 of subframe and lower house 4 are provided with the through hole of supporting leg traverse for U-shaped connector 2, when subframe and vehicle frame 1 connect, U-shaped connector 2 is U-bolt, two supporting legs of U-bolt are corresponding one stay tube respectively, and sequentially pass through lower house 4, prop up stay tube, upper shell 3 and vehicle frame 1, then pass through fastening bolt fastening, the installing port for fastening bolt can be offered on vehicle body, or on vehicle body, preset installing space.
In the present embodiment, the inner side of upper shell 3 is or/and the inner side of lower house 4 is formed for a location convex for stay tube location (for location convex 7 and location convex 7a in figure)；In the present embodiment, the inner side of upper shell 3 and the inner side of lower house 4 are provided with location convex, for the location, end to a stay tube.
In the present embodiment, compress between vehicle frame 1 and subframe and be provided with at least one of which vibration isolator 6；Vibration isolator 6 is arranged between vehicle frame 1 and subframe, and compacted under the effect of U-shaped connector 2, can play the effect of vibration isolation, and reduce the noise between vehicle frame 1 and subframe.
In the present embodiment, the end of a stay tube and the location convex of corresponding position form cone match；As described in Figure, location convex is frustum structure, and the end of a stay tube is provided with the cone tank coordinated with frustum；Not only have and coordinate positioning relation preferably, and can prevent stress from concentrating.
In the present embodiment, inside vehicle frame 1, each supporting leg of corresponding U-shaped connector is provided with one for the reinforcement convex (for strengthening convex 8 and strengthening convex 8a in figure) strengthening coupling stiffness, strengthens being provided with the via for supporting leg traverse on convex.
What finally illustrate is, above example is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described in detail with reference to preferred embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent replacement, without deviating from objective and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
