To facilitate understanding of the technical solution of the present application, prior to the detailed description, an existing intermediate support assembly will be described first.
At present, the middle support assembly of a commercial vehicle comprises a bearing assembly, a backing ring, a bracket assembly and other fasteners which are arranged from inside to outside, wherein the bearing assembly is connected with a transmission shaft assembly, the axis of the bearing assembly is consistent with the axis of the transmission shaft assembly, and the bracket assembly needs to be rigidly connected with a vehicle frame.
However, the front end and the rear end of the transmission shaft assembly are respectively connected with the transmission assembly and the drive axle assembly, and the transmission assembly and the drive axle assembly have a height difference on the whole vehicle, so that an angle is formed between the axis of the transmission shaft assembly and the vehicle frame. At this time, an angle deviation also occurs between the axis of the bearing assembly supporting the transmission shaft assembly and the axis of the bracket assembly, so that the backing ring between the bearing assembly and the bracket assembly has a distortion problem, and the backing ring is easily damaged early in the subsequent use of the vehicle.
In the current vehicle assembly process, in order to avoid the problem of premature damage of a backing ring, a plurality of beam hanging plates with angles are manufactured to realize angle compensation. However, this affects the weight reduction of the vehicle and increases the manufacturing cost of the vehicle.
In view of the above, the present application provides an intermediate support assembly and a vehicle that can preferably improve the above-described problems.
The intermediate support assembly and the vehicle of the present application will be described with reference to the accompanying drawings.
FIG. 1 is a schematic view of an intermediate support assembly according to an embodiment of the present application; FIG. 2 is a schematic structural view of an upper bracket assembly of the intermediate support assembly shown in FIG. 1; FIG. 3 is a schematic view of the lower bracket assembly of the intermediate support assembly of FIG. 2; FIG. 4 is a schematic view of the grommet of the intermediate support assembly of FIG. 1; FIG. 5 is a schematic view of the mounting of the intermediate support assembly of FIG. 1 to a vehicle. For the purpose of illustration, only the structures described in connection with the present application are illustrated in the drawings.
At least one embodiment of the present application discloses an intermediate support assembly 100 for coupling a driveshaft assembly 920 (shown in FIG. 5) of a vehicle to a vehicle frame 910. The transmission shaft assembly 920 is connected between the transmission case and the drive axle to transmit torque. The intermediate support assembly 100 includes a bracket assembly 10, a backing ring 30, and a bearing assembly 40. The bracket assembly 10 provides a mounting base and a frame protection for the backing ring 30 and the bearing assembly 40, the backing ring 30 is flexibly connected to the bracket assembly 10, and the bearing assembly 40 is connected to the backing ring 30 for supporting the transmission shaft assembly 920.
The support assembly 10 includes an upper support assembly 11 and a lower support assembly 12 in butt joint with the upper support assembly 11. The upper bracket assembly 11 is generally an inverted U-shaped structure, and the lower bracket assembly 12 is a U-shaped structure coupled to an open end of the upper bracket assembly 11, so that the two are mutually matched to form a supporting space. In addition, the lower bracket assembly 12 is rotatably connected to the upper bracket assembly 11 about an axis to have a certain swing angle with respect to the upper bracket assembly 11 about the axis under an external force.
Specifically, the upper bracket assembly 11 includes an upper bracket main body 111, a first upper bracket side plate 112, and a second upper bracket side plate 113. The upper bracket main body 111 extends in a first direction, and the first upper bracket side plate 112 and the second upper bracket side plate 113 are formed by extending both ends of the upper bracket main body 111 in the first direction in the same direction.
The lower bracket assembly 12 includes a lower bracket main body 121, a first lower bracket side plate 122, and a second lower bracket side plate 123. The lower bracket body 121 extends in the same first direction as the upper bracket body 111, and the first lower bracket side plate 122 and the second lower bracket side plate 123 are formed by extending both ends of the lower bracket body 121 in the first direction in the same direction.
In this embodiment, one end of the first lower rack side plate 122 and one end of the second lower rack side plate 123 are rotatably connected to the first upper rack side plate 112 and the second upper rack side plate 113, respectively, around an axis, so that the lower rack main body 121 can rotate relative to the upper rack main body 111 under the action of an external force. Wherein the first direction is a horizontal direction.
In addition, in some embodiments, the first upper bracket side plate 112 and the second upper bracket side plate 113 are respectively provided with a first oblong hole 114 and a second oblong hole 115, and the other ends of the first lower bracket side plate 122 and the second lower bracket side plate 123, which are far away from the axis, are slidably connected to the first oblong hole 114 and the second oblong hole 115.
The end of the first lower bracket side plate 122, which is far away from the axis, of the second lower bracket side plate 123 can move in the first oblong hole 114 and the second oblong hole 115, so that the end of the first lower bracket side plate 122 and the end of the second lower bracket side plate 123 are driven to rotate around the axis relative to the first upper bracket side plate 112 and the second upper bracket side plate 113, and the rotation of the lower bracket assembly 12 relative to the upper bracket assembly 11 is realized.
The first oblong hole 114 and the second oblong hole 115 may be arranged identically or differently, and in the embodiment of the present application, the first oblong hole 114 and the second oblong hole 115 are arranged identically and symmetrically distributed. It will be readily appreciated that the length of the first and second oblong holes 114, 115 is the angle at which the first and second lower bracket side plates 122, 123 can rotate relative to the first and second upper bracket side plates 112, 113. Therefore, the first oblong hole 114 and the second oblong hole 115 should be provided according to the assembly requirements of the vehicle.
In some embodiments, the upper bracket assembly 11 is pre-fastened with the fastener 50, and the upper bracket main body 111 is fastened to the frame 910 of the vehicle by means of the fastener 50. For example, the fastener 50 may be a nut that is pre-welded to the upper bracket body 111.
Specifically, during assembly of the intermediate support assembly 100 to the vehicle frame 910, the fastener 50 is directly tightened to both the upper bracket assembly 11 and the vehicle frame 910 after the upper bracket assembly 11 is aligned with its installed position on the vehicle frame 910 by pre-tightening the fastener 50 on the upper bracket assembly 11. If the fastening member 50 is not pre-fastened to the upper bracket assembly 11, and the upper bracket assembly 11 is aligned with the mounting position of the upper bracket assembly 11 on the vehicle frame 910, then the fastening of the upper bracket assembly 11 and the vehicle frame 910 is difficult due to the small supporting space, which increases the assembly cost.
The backing ring 30 is accommodated in the supporting space, and the backing ring 30 includes a first buffer portion 31, a second buffer portion 32, a third buffer portion 33 and a fourth buffer portion 34. The first buffer portion 31 and the second buffer portion 32 are disposed opposite to each other, and the third buffer portion 33 and the fourth buffer portion 34 are disposed opposite to each other and connected between the first buffer portion 31 and the second buffer portion 32. Meanwhile, the first buffer portion 31, the second buffer portion 32, the third buffer portion 33 and the fourth buffer portion 34 collectively enclose a mounting groove 35 for mounting the bearing assembly 40.
Taking fig. 1 as an example, the first buffer portion 31 is located above the supporting space in the rack assembly 10, the second buffer portion 32 is located below the supporting space in the rack assembly 10, the third buffer portion 33 is located at the left of the supporting space in the rack assembly 10, and the fourth buffer portion 34 is located at the right of the supporting space in the rack assembly 10. It is understood that in other embodiments, the position of each buffer portion in the backing ring 30 may be determined according to the requirement, and is not limited herein.
Specifically, in the present embodiment, in order to realize the rotation of the lower rack assembly 12 relative to the upper rack assembly 11, the first buffer portion 31 will be in clearance fit with the inner side surface of the upper rack main body 111 in the upper rack assembly 11, and the second buffer portion 32 will be in soft connection with the inner side surface of the lower rack main body 121 in the lower rack assembly 12; the third buffer portion 33 is flexibly connected to the inner surface of the first lower frame side plate 122 of the lower frame assembly 12, and the fourth buffer portion 34 is flexibly connected to the inner surface of the second lower frame side plate 123.
In addition, the first buffer portion 31 may be designed to have a trapezoidal shape to satisfy a buffer function when the propeller shaft assembly 920 jumps up. Specifically, in the present embodiment, two sides of the first buffer portion 31 along the first direction are reduced by a certain inclination angle, and two triangles are formed with the inner side of the upper bracket assembly 11. After the first buffer 31 is removed, the vehicle can be reduced in weight.
It should also be noted that honeycomb holes or weight-reducing holes of larger size may be provided at other locations on the grommet 30, taking rigidity and durability into consideration.
The backing ring 30 may be a rubber backing ring 30, and the rubber backing ring 30 may satisfy a buffering function when the transmission shaft assembly 920 jumps up. Of course, the backing ring 30 may also include other soft material backing rings 30, as long as the effect of buffering the transmission shaft assembly 920 is achieved.
Although the rubber grommet 30 has good cushioning properties, the rubber grommet 30 is not connected to the lower bracket assembly 12 firmly, which results in a failure that the rubber grommet 30 is easily separated from the lower bracket assembly 12 by the axial force of the propeller shaft assembly 920 during the driving of the vehicle, and thus the durability of the intermediate support assembly 100 is not high.
Therefore, in some embodiments, the second buffer portion 32 will be vulcanized and fixedly connected to the inner side of the lower bracket main body 121 of the lower bracket assembly 12; the third buffer portion 33 is to be surface-vulcanization-fixedly connected to the inner side of the first lower bracket side plate 122 of the lower bracket assembly 12, and the fourth buffer portion 34 is to be surface-vulcanization-fixedly connected to the inner side of the second lower bracket side plate 123.
In other embodiments, the groove wall of the assembling groove 35 of the rubber grommet 30 is fixedly connected with the bearing assembly 40 by vulcanization, so as to improve the connection stability of the grommet 30 and the bearing assembly 40.
The bearing assembly 40 includes a bearing seat and a bearing. More specifically, the bearing housing is fitted into the fitting groove 35, the bearing housing is seated in the bearing housing, and the propeller shaft assembly 920 is rotatably coupled to the bearing.
In practical application, after the transmission shaft assembly 920 is installed in the bearing, the transmission shaft assembly can drive the lower support assembly 12 to rotate relative to the upper support assembly 11 until the axis of the bearing assembly 40 is substantially coincident with the axis of the support assembly 10. That is, the drive shaft assembly 920 is substantially coincident with the axis of the carrier assembly 10. Thus, the angular deviation between the axis of the transmission shaft assembly 920 and the axis of the bracket assembly 10 is reduced, thereby preventing the backing ring 30 between the two from being distorted and deformed, and improving the durability of the intermediate bearing assembly 100.
As a general concept of the present application, there is also provided a vehicle including a frame 910, a propeller shaft assembly 920, and an intermediate support assembly 100 as described above, wherein the upper bracket assembly 11 is coupled to the frame 910, and the propeller shaft assembly 920 is rotatably coupled to the bearing assembly 40. A vehicle adopting the middle support assembly 100 does not need to be matched with and produce various types of hanger plate cross beams. This both optimizes vehicle weight and reduces manufacturing costs. In addition, the vehicle center support assembly 100 has high durability and excellent weight reduction effect.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
