Abstract
A modified structure of a front sleeve in an auxiliary frame of a vehicle is composed of a tubular component, wherein the radial section of the tubular component is round, a necking part is arranged at the upper portion of the tubular component and is located at the lower side of the upper end surface of the tubular component, the diameter of the necking part is smaller than that of a main body of the tubular component and smaller than the diameter of the upper end surface of the tubular component, and the diameter of the upper end surface of the tubular component is smaller than that of the main body of the tubular component. According to the modified structure of the front sleeve in the auxiliary frame of the vehicle, a necking structure is arranged at the upper portion of the front sleeve, and when the auxiliary frame is assembled with a vehicle body, an upper piece and a lower piece of the auxiliary frame are fixed in the necking position of the front sleeve. Even though welding dangers exist, parts are prevented from falling off or moving, and therefore safety is largely increased.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to the vehicle subframe, particularly the improvement structure of front sleeve in a kind of vehicle subframe.
Background technology:
The vehicle subframe is connected with vehicle body by front sleeve.In the prior art, front sleeve is cylindrical, by constituting through welding behind the metal sheet bending ram.Hidden danger such as the dry joint that exists during welding, sealing-off cause in the driving process front sleeve and subframe to come off easily or are shifted, and influence the safety of subframe.
Summary of the invention:
The purpose of this utility model is to provide the improvement structure of front sleeve in a kind of vehicle subframe, and the welding hidden danger that the improvement structure of front sleeve will solve front sleeve in the prior art in the described this vehicle subframe causes front sleeve and subframe to come off easily or is shifted, influences the technical matters of subframe safety.
The improvement structure of front sleeve in this vehicle subframe of the present utility model, constituted by a tubular member, the radial section of described tubular member is rounded, wherein, described tubular member is provided with a reducing part at an upper portion thereof, described reducing partly is positioned at the downside of the upper surface of tubular member, and the diameter of reducing part is less than the diameter of tubular member body, and less than the diameter of tubular member upper surface.
Further, the diameter of tubular member upper surface is less than the diameter of tubular member body.
Principle of work of the present utility model is: when subframe and vehicle body assembling, sheet is fixed on reducing place of front sleeve about the subframe.Even there is hidden danger in welding, also the problem that can avoid part to come off or be shifted has increased safety greatly.
The utility model and prior art are compared, and its effect is actively with tangible.The utility model is provided with throat structure on front sleeve top, and when subframe and vehicle body assembling, sheet is fixed on reducing place of front sleeve about the subframe.Even there is hidden danger in welding, also the problem that can avoid part to come off or be shifted has increased safety greatly.
Description of drawings:
Fig. 1 is the scheme drawing of the improvement structure of front sleeve in the vehicle subframe of the present utility model.
The specific embodiment:
Embodiment 1:
As shown in Figure 1, the improvement structure of front sleeve in the vehicle subframe of the present utility model, constituted by a tubular member 1, the radial section of described tubular member 1 is rounded, wherein, described tubular member 1 is provided with a reducing part 2 at an upper portion thereof, and described reducing part 2 is positioned at the downside of the upper surface of tubular member 1, the diameter of reducing part 2 is less than the diameter of tubular member 1 main body, and less than the diameter of tubular member upper surface 3.
Further, the diameter of tubular member upper surface 3 is less than the diameter of tubular member 1 main body.
The principle of work of present embodiment is: when subframe and vehicle body assembling, sheet is fixed on reducing place of front sleeve about the subframe, connects by the coupling of the welding on the tubular member 1 face 4, welding coupling face 5.Even there is hidden danger in welding, also the problem that can avoid part to come off or be shifted has increased safety greatly.
Claims (2)
