Technical Field

The utility model relates to the technical field of vehicles, in particular to a transmission shaft hanging structure, a chassis and a vehicle.

Background

The chassis of an automobile is a part of the vehicle and is critical to the performance of the vehicle. Generally, an automobile chassis comprises a frame, and the frame is connected with a hanging bracket which can be used for connecting a transmission shaft. The existing chassis, after the transmission shaft is connected with the hanging bracket, the position of the transmission shaft is kept unchanged, and the relative positions of the transmission shaft and the frame are different for different vehicle types. However, as vehicles are continuously upgraded and improved, parameters such as the height of the transmission shaft and the angle between the transmission shaft and the vehicle frame are also changed, and different vehicle frames are required to meet different parameters, so that the conventional vehicle frames are low in universality, and the production cost is increased.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 and 2, a propeller shaft suspension structure in an embodiment of the present utility model may include two oppositely disposed frame rails 10 and a suspension bracket 20 located between the two frame rails 10. The web of each frame rail 10, i.e. the side of the frame rail 10 facing the other frame rail 10, is provided with a plurality of mounting structures 11, the plurality of mounting structures 11 on the two frame rails 10 being in one-to-one correspondence such that the two mounting structures 11 on both sides form a set of mounting stations.

Of the plurality of mounting structures 11 provided on each frame rail 10, a part of the mounting structures 11 are aligned in the longitudinal direction of the frame rail 10 (y direction in fig. 2), that is, a part of the mounting stations are aligned in the longitudinal direction of the frame rail 10. The hanger bracket 20 is mounted on both sides of each of the two mounting structures 11 at one of the mounting stations to provide a stable connection between the hanger bracket 20 and the frame rail 10. The suspension bracket 20 may be used to connect the drive shaft 30, and the first end of the drive shaft 30 may be fixedly connected to the suspension bracket 20 to ensure a stable connection between the drive shaft 30 and the suspension bracket 20.

In the present embodiment, referring to fig. 1 to 3 together, the dashed suspension bracket 20 in fig. 1 may be understood as the suspension bracket 20 after changing the installation position, and the dashed transmission shaft 30 in fig. 3 may be understood as the transmission shaft 30 after changing the installation position. Suspension brackets 20 may be selectively mounted to one of the mounting stations, with the position of the second end of drive shaft 30 opposite the first end being fixed, and drive shaft 30 being considered integral with suspension brackets 20, the position of the first end of drive shaft 30 being changed when the mounting station of suspension brackets 20 is changed, thereby changing the angle or height between drive shaft 30 and frame rail 10. Alternatively, as the length of drive shaft 30 changes, a stable attachment of drive shaft 30 to frame rail 10 may be accomplished by changing the mounting station of suspension brackets 20.

It should be noted that, in practical use, the suspension bracket 20 in fig. 1 is connected to two frame rails 10 at both sides thereof, and the structure in fig. 1 is merely for illustrating a change in mounting position between the suspension bracket 20 and the frame rails 10.

Further, with continued reference to fig. 2, of the plurality of mounting structures 11 of each frame rail 10, a portion of the mounting structures 11 are aligned along the extending direction (x-direction in fig. 2) of the frame rail 10, that is, a portion of the mounting stations are aligned in the horizontal direction. When the hanger bracket 20 is mounted between two frame rails 10, it may be mounted at any mounting station in the longitudinal direction of the frame rail 10 or at any mounting station in the horizontal direction. It will be appreciated that the angle between the drive axle 30 and the frame is changed by changing the mounting position of the suspension brackets 20 in the horizontal direction, i.e., between the first end of the drive axle 30 and the frame rail 10.

In the present embodiment, in designing the mounting structure 11 on the frame rail 10, the plurality of mounting structures 11 may be arranged only in the longitudinal direction of the frame rail 10, that is, only one mounting structure 11 in the horizontal direction. Alternatively, the plurality of mounting structures 11 may be arranged only in the horizontal direction, that is, only one mounting structure 11 in the longitudinal direction of the frame rail 10. Alternatively, the plurality of mounting structures 11 may be arranged in both the horizontal direction and the longitudinal direction, so that the number of mounting structures 11 may be increased, and thus, the design of more parameters such as angle, height, etc. of the transmission shaft 30 may be satisfied, so as to further improve the universalization of the hanging structure of the transmission shaft.

As an embodiment, the mounting structure 11 may be a mounting hole, and the suspension bracket 20 is connected to the mounting hole by a threaded fit. For example, the suspension bracket 20 may be connected to the mounting hole by means of bolts or screws. That is, the suspension is detachably connected to the mounting hole, and when the transmission 30 is required to be maintained or replaced, the suspension bracket 20 can be detached from the frame rail 10 by screwing the bolt or screw out of the mounting hole.

In some embodiments, referring to fig. 4 and 5, mounting plates 40 may be provided on both sides of the suspension bracket 20, respectively, and the mounting plates 40 may be provided with openings 41 corresponding to the mounting holes. When suspension brackets 20 are to be attached to frame rail 10, mounting plate 40 may be placed in close proximity to the web of frame rail 10, and openings 41 in mounting plate 40 are aligned with one of the mounting holes of frame rail 10 so that bolts or screws pass through openings 41 and the mounting holes in sequence. It will be appreciated that when mounting plate 40 is provided, the surface of mounting plate 40 more readily conforms to the surface of frame rail 10, thereby improving the stability of the connection between suspension brackets 20 and frame rail 10.

Further, the number of mounting plates 40 provided on each side of the suspension bracket 20 may be two, wherein one mounting plate 40 is fixedly connected to the top of the suspension bracket 20 and the other mounting plate 40 is fixedly connected to the bottom of the suspension bracket 20. Thus, when hanger 20 is mounted to frame rail 10, two mounting plates 40 are respectively coupled to two mounting holes in frame rail 10, thereby further improving the stability of the connection between hanger 20 and frame rail 10.

It should be noted that the number of the holes 41 provided in each mounting plate 40 may be one or more, and in this case, the plurality of holes 41 in the mounting plates 40 are respectively in one-to-one correspondence with the plurality of mounting holes of the frame rail 10. When a plurality of openings 41 are provided in mounting plate 40, the strength of the connection between suspension brackets 20 and frame rail 10 can be further improved.

In this embodiment, the mounting plate 40 and the suspension bracket 20 may be integrally formed, for example, the mounting plate 40 is connected to the suspension bracket 20 by welding, so as to ensure structural stability therebetween.

Based on the same inventive concept, embodiments of the present utility model may also provide a chassis including the propeller shaft hanging structure as described in the above embodiments.

Based on the same inventive concept, the embodiment of the utility model can also provide a vehicle comprising the chassis.

It will be apparent to those skilled in the art that various modifications and variations can be made to the embodiments of the present utility model without departing from the spirit and scope of the utility model. Thus, it is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
