Description

Technical Field

[0001] The utility model belongs to the technical field of bus manufacturing, and particularly relates to a knuckle end fixing seat of a front suspension of a 6-meter full-load-bearing bus. Background Art

[0002] The knuckle end fixing seat of the front suspension is a connecting component for connecting the front suspension knuckle and the vehicle frame. Currently, the existing structure of the knuckle end fixing seat of the front suspension, as Figure 1-2 shown: The fixing seat is mainly composed of an upper connecting plate, front and rear reinforcing plates, a right L-shaped fixing piece and a left fixing piece. The back of the upper connecting plate is fixedly connected to a partial facade of the vehicle frame by a plurality of M14 flange bolts. The front suspension knuckle is fixed between the right L-shaped fixing piece and the left fixing piece by M20 flange bolts. This structural design has disadvantages: the distance between the bottom plane of the front and rear reinforcing plates and the upper plane of the front suspension knuckle is too small, which easily causes the front suspension knuckle to hit the bottom plane of the front and rear reinforcing plates during the running and bouncing of the vehicle; in addition, the material used is too redundant or even over-designed, without considering the requirements of the overall vehicle lightweight design. Content of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides a knuckle end fixing seat of a front suspension of a 6-meter full-load-bearing bus.

[0004] The technical solution adopted by the utility model is that the knuckle end fixing seat of the front suspension of the 6-meter full-load-bearing bus includes a "7"-shaped right mounting plate. The left end of the top surface of the right mounting plate is welded with a left mounting plate. The side plate of the right mounting plate and the left mounting plate are symmetrically arranged in a semi-circular structure and mounting holes are correspondingly opened in the middle. The right end of the top surface of the right mounting plate is welded to the bottom end of a side connecting plate, and a plurality of mounting holes are opened on the side connecting plate.

[0005] Preferably, 3 strip-shaped weight-reducing holes are evenly spaced along the length direction on the top surface of the right mounting plate.

[0006] Preferably, a reinforcing rib is provided between two adjacent strip-shaped weight-reducing holes. The reinforcing rib is triangular, and the vertical side and the bottom side are respectively welded to the side connecting plate and the top surface of the right mounting plate.

[0007] Preferably, the right mounting plate is processed and bent integrally from a Q355B steel plate with a thickness of 8 mm.

[0008] Compared with the prior art, the beneficial effects of the present utility model are as follows: The front and rear reinforcing plates on the front and rear sides are cancelled, completely eliminating the risk of impact between components during the running and bouncing of the vehicle. Among them, three strip-shaped weight-reducing holes are designed on the top surface of the right mounting plate, and the side plate of the right mounting plate and the lower part of the left mounting plate adopt large arc designs to reduce weight, meeting the requirements of the overall vehicle lightweight design.

[0013] The following will further explain and illustrate the present utility model in conjunction with the drawings of the specification, so as to facilitate better understanding by professionals in the field.

[0014] Embodiment 1

[0015] As Figure 3-4 shown, based on the fixed seat at the ear end of the front suspension guide arm of a 6-meter fully loaded bus, it includes a "7"-shaped right mounting plate 1. The left end of the top surface of the right mounting plate 1 is welded to the left mounting plate 2. The side plate of the right mounting plate 1 and the left mounting plate 2 are symmetrically arranged in a semi-circular structure and corresponding mounting holes are provided in the middle. The bottom end of the side connection plate 3 is welded to the right end near the top surface of the right mounting plate 1, and multiple mounting holes are provided on the side connection plate 3. Among them, three strip-shaped weight-reducing holes 4 are evenly spaced along the length direction on the top surface of the right mounting plate 1. A reinforcing rib 5 is provided between two adjacent strip-shaped weight-reducing holes 4. The reinforcing rib 5 is triangular, and the vertical side and the bottom side of the reinforcing rib 5 are respectively welded to the side connection plate 3 and the top surface of the right mounting plate 1.

[0016] The right mounting plate 1 is processed and bent into one piece from a Q355B steel plate with a thickness of 8 mm. The side connecting plate 3 and the left mounting plate 2 are both made of Q355B steel plates with a thickness of 8 mm. After the above-mentioned components are welded and assembled according to the design by CO2 gas shielded welding, when installing and fixing the total body components of the fixed seat, 6 M14 flange bolts and flange nuts are used to fix it on the side of the local vertical surface of this structural frame. When installing the front suspension guide arm components, 1 M20 flange bolt and 1 M20 flange nut are used to align the front suspension guide arm to the hole positions on the right mounting plate and the left mounting plate, and a professional pneumatic tool is used to tighten the bolts. Finally, a torque wrench is used to check whether the tightened torque meets the requirements of the parameters in the design and process documents.

[0017] For the ear end fixed seat of the front suspension guide arm designed by the present utility model, the front and rear reinforcing plates on the original front and rear sides are cancelled, completely eliminating the risk of impact between components during the vehicle operation and bouncing; among them, three strip-shaped weight-reducing holes are designed on the top surface of the right mounting plate, and the side plate of the right mounting plate and the lower part of the left mounting plate adopt large arc designs to reduce weight, meeting the requirements of the vehicle's lightweight design.

[0018] The embodiments described above are only descriptions of the preferred embodiments of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit and principle of the present utility model, various deformations and improvements made by those skilled in the art to the technical solutions of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
