Embodiment Construction
[0012] Example figure 2 and image 3 As shown, it includes a V-shaped limiting groove 1, a U-shaped plate 2, a baffle plate 3, a fastening belt 4 and a fastener 5, and two V-shaped limiting grooves 1 are welded on the U-shaped plate 2, one left and one right. At the inner U-shaped bend, the baffle 3 is welded to the front opening of the U-shaped plate 2, so that the V-shaped limiting groove 1, the U-shaped plate 2 and the baffle 3 form an opening at both ends, and there is a V-shaped limiting groove inside limited cavity.
[0013] Such as Figure 4 As shown, the baffle plate 3 is equipped with a fastening belt 4, the fastening belt 4 is connected with a fastener 5, and the fastening belt 4 is fixedly connected with the guide plate 6. The baffle 3 is an unloading tank structure.
[0014] When processing this device, the V-shaped limiting groove 1 must have double-sided inverted welding grooves, the V-shaped limiting groove 1 and the U-shaped plate 2 are welded and fixed, a...

The invention belongs to the automobile field, and relates to a design method of a safe and reliable front air suspension guide plate protecting device for a passenger car. The front air suspension guide plate protecting device is characterized by comprising V-shaped limit grooves (1), a U-shaped plate (2), a baffle plate (3), a fastening band (4) and a fastening piece(5), wherein, the two V-shaped limit grooves (1) are fixedly connected on the left side and the right side of the U-shaped bending position at the inner side of the U-shaped plate (2) respectively; the baffle plate (3) is fixedly connected at an opening at the front side of the U-shaped plate (2) so that the V-shaped limit grooves (1), the U-shaped plate (2) and the baffle plate (3) form a cavity which is equipped with openings at two ends and V-shaped limit grooves for limit; the baffle plate (3) is equipped with the fastening band (4); the fastening band (4) is connected with the fastening piece (5); and the fastening band (4) is fixedly connected with a guide plate (6). The front air suspension guide plate protecting device has simple structure, high safety and convenient processing and assembly.
Description
technical field [0001] The invention belongs to the field of automobiles, in particular to a design method of a safe and reliable front air suspension guide plate protection device of passenger cars. Background technique [0002] German MAN company discloses a kind of tourist bus suspension guide plate mechanism, as figure 1 shown. The main function of the guide plate in the suspension is that one end is connected to the front axle through the airbag support, and the other end is connected to the frame through the guide plate support. The connection method is as follows: figure 2 shown. Its main function is to guide and drive the movement of the front axle in the suspension system, and it is a key part and stressed part in the suspension system. The strength of this part fully meets the requirements in terms of design, but if there is a problem with the material of the part during processing or the processing is not strictly in accordance with the drawing, the guide plat...
