Background technology
Mode is an important indicator in evaluation structure part NVH (English full name: Noise, Vibration, Harshness, Chinese full name: noise, vibration and sound vibration roughness) performance.Need to pay close attention to Mode Problems in fore sub frame design process, the model frequency of design subframe needs each order frequency section avoiding driving engine, produces larger vibration and is directly delivered to vehicle body, cause the reduction of traveling comfort to avoid modal coupling.
Designer takes structure optimization scheme to improve subframe mode.Fig. 4 is auxiliary frame structure schematic diagram of the prior art.Existing subframe adopts partial reinforced structure, specifically arranges connecting panel 3 at the middle part of subframe upper plate (not drawing in figure) and subframe lower plate 2 and is welded and fixed, realizing the local strengthening of subframe, thus strengthens rigidity, to improve mode.
But this structure just local is strengthened, obvious not to the lifting of entirety, effect is unsatisfactory.
Utility model content
An object of the present utility model to provide a kind of subframe, and it has carried out overall reinforcement, and good rigidity effectively can improve mode.
The utility model further object is to provide a kind of vehicle, and makes described vehicle can promote NVH performance, increases vehicle comfort level.
Especially, the utility model provides a kind of subframe, comprise the subframe upper plate and subframe lower plate that are fixed together, also comprise the connecting panel be fixed between described subframe upper plate and described subframe lower plate, described connecting panel is arranged along the length direction of described subframe.
Preferably, the two ends of described connecting panel extend along the length direction of described subframe, and run through described subframe upper plate and described subframe lower plate.
Further, described subframe is connected with the left front attachment point of vehicle body and right front attachment point and arranges goat's horn pipe at corresponding attachment point place, and the two ends of described connecting panel extend to corresponding goat's horn pipe place and form transverse integral in the welding of this place strengthens structure.
Further, described connecting panel is vertically arranged, and its top and described subframe upper plate are fixed together, and bottom is fixed on described subframe lower plate place.
Preferably, have elongated hole bottom described subframe lower plate, top and the described subframe upper plate of described connecting panel are fixed, and bottom is close to the elongated hole of described subframe lower plate and to realize with described subframe lower plate by stuff up a crack welding fixing.
Especially, the utility model additionally provides a kind of vehicle, comprises subframe as above.
Subframe of the present utility model is regional area reinforcement structure in the middle of subframe by arranging connecting panel compared to brace panel in prior art between subframe upper plate and subframe lower plate, the connecting panel that the utility model is strengthened elongates and strengthens, whole subframe upper plate and subframe lower plate is made to combine more complete, overall torsion and bending stiffness promote comparatively large, and therefore mode is increased dramatically.And then the traveling comfort with the vehicle of described subframe be have also been obtained significantly promote, and also few to the increase of tare, can not impact other performances of vehicle.
According to hereafter by reference to the accompanying drawings to the detailed description of the utility model specific embodiment, those skilled in the art will understand above-mentioned and other objects, advantage and feature of the present utility model more.
Accompanying drawing explanation
Hereinafter describe specific embodiments more of the present utility model with reference to the accompanying drawings by way of example, and not by way of limitation in detail.Reference numeral identical in accompanying drawing denotes same or similar parts or part.It should be appreciated by those skilled in the art that these accompanying drawings may not be drawn in proportion.In accompanying drawing:

Detailed description of the invention
Embodiment 1
Fig. 1 is the front view of the subframe according to the utility model embodiment.Fig. 2 is the top view of subframe shown in Fig. 1.Fig. 3 is the detonation configuration schematic diagram of subframe shown in Fig. 1.As shown in Figure 1, can also see Fig. 2 or Fig. 3, the present embodiment take Fig. 1 as main being illustrated, subframe can comprise the subframe upper plate 1 and subframe lower plate 2 that are fixed together in general manner, also comprise the connecting panel 5 (see Fig. 2) be fixed between described subframe upper plate 1 and subframe lower plate 2, described connecting panel 5 (see Fig. 2) is arranged along the length direction of described auxiliary frame structure.
In the present embodiment, be fixedly connected with and be preferably welding.In other embodiments, other are fixedly connected with mode can also to adopt riveted joint or bolt connection etc.
The present embodiment is regional area reinforcement structure in the middle of subframe compared to brace panel in prior art, the connecting panel 5 that this programme is strengthened elongates and strengthens, whole subframe upper plate 1 is made to be combined more complete with subframe lower plate 2, overall torsion and bending stiffness promote comparatively large, and therefore mode is increased dramatically.
In order to farthest improve subframe intensity by connecting, the two ends of described connecting panel 5 can extend along subframe length direction, and run through described subframe upper plate 1 and described subframe lower plate 2.Like this by arranging penetration type connecting panel 5 between subframe upper plate 1 and subframe lower plate 2, on the whole subframe upper plate 1 and subframe lower plate 2 are farthest strengthened, to promote mode.
Further, as shown in Figure 2, described subframe and right front attachment point left front with vehicle body is connected and is provided with goat's horn pipe 4 at corresponding attachment point place, and the two ends of described connecting panel 5 extend to corresponding goat's horn pipe 4 place and form transverse integral in the welding of this place strengthens structure.
Particularly, described connecting panel 5 is vertically arranged, and its top and described subframe upper plate 1 weld together, lower weld is fixed on described subframe lower plate 2 place.More specifically, have elongated hole bottom described subframe lower plate 2, top and the described subframe upper plate 1 of described connecting panel 5 are welded and fixed, and bottom is close to the elongated hole of described subframe lower plate 2 and to realize with subframe lower plate 2 by stuff up a crack welding fixing.The integral structure that such connection mode is formed, globality is strong, to promote overall rigidity, reaches the effect promoting mode further.
