Description

Technical Field

[0001] The invention belongs to the field of automobiles, relates to a suspension beam body and a bridge housing installation technology, and specifically is a bridge housing installation structure based on a suspension beam body. Background Art

[0002] Rigid axles and their supporting air suspension technologies have been developed to a very mature level and are widely used in commercial vehicles at home and abroad. The axle housing and suspension need to bear the vertical load from the ground and the vehicle body, as well as the longitudinal impact force during braking and starting, to meet driving needs. As the main load-bearing components, the axle housing and beam body have extremely high requirements for their service life and load bearing capacity.

[0003] In the prior art, since the driving bevel gear of the transmission shaft of the vehicle is generally designed with an inclination angle, the existing bridge housing 501 needs to be installed by designing a plate seat 501 with an inclination angle, as shown in the following example. Figure 1 As shown in FIG. 1 , a plate seat 501 with an inclined angle is provided on the suspension beam 101, and the bridge housing 501 and the beam 101 are locked by bolts 401. Since the bridge housing 501 and the beam 101 are in direct contact with each other on the upper and lower surfaces, the stress will be mainly concentrated on the upper and lower contact surfaces of the two. When the vehicle is braking and starting, the thrust rod will form a longitudinal impact force on the bridge housing 501 and the beam 101 (such as Figure 1 When the force is applied in the middle and Fa directions, the bridge housing 501 and the beam body 101 are at risk of cracking on the upper and lower surfaces.

[0004] Therefore, a bridge housing mounting structure based on a suspension beam body is needed to solve the above problems. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art; to this end, the present invention proposes a bridge housing mounting structure based on a suspension beam body, so as to effectively improve the ability to resist vertical loads and longitudinal impact forces, avoid cracking of the upper and lower contact surfaces between the bridge housing and the beam body, and thus extend the service life of the device. The present invention arranges a beam body, a mounting bracket, an adapter seat, a through-connector, a bridge housing mounting seat and a bridge housing body, and the mounting bracket is welded to one side of the beam body, and the through-connector is sequentially connected to the mounting bracket, the adapter seat and the bridge housing mounting seat to complete the fixation, so that the bridge housing body is fixed above the adapter seat under the action of the bridge housing mounting seat, that is, the bridge housing body and the beam body are not in contact, and then when the bridge housing body and the beam body are subjected to longitudinal impact force, the force can be dispersed on the bridge housing mounting seat, the adapter seat and the mounting bracket. Compared with the method in the prior art where the longitudinal impact force directly acts on the contact surface between the bridge housing body and the beam body, the cracking of the upper and lower contact surfaces between the bridge housing and the beam body can be avoided, thereby achieving the purpose of extending the service life of the bridge housing body and the beam body.

[0027] Furthermore, the second connecting plate is arranged outside the axle housing body and can swing relative to the axle housing body;

[0028] Wherein, during the swinging process of the second connecting plate, the side of the second connecting plate away from the first connecting plate is always perpendicular to the length direction of the through-connecting member;

[0029] The fixing member includes a hinged rod and a telescopic rod, so that the first connecting plate, the second connecting plate and the fixing member are surrounded to form a deformable quadrilateral structure;

[0046] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Embodiment 1

[0048] See also Figure 2 and Figure 3 In a first aspect, an embodiment of the present invention provides a bridge housing mounting structure based on a suspension beam body, including a beam body 1, a mounting bracket 2, an adapter seat 3, a through-connector 4, a bridge housing mounting seat 5 and a bridge housing body 6.

[0049] The mounting bracket 2 is welded on both sides of the beam body 1 to provide support for the installation of the adapter seat 3 and the through-connector 4 .

[0050] The adapter seat 3 is arranged on the upper surface of the beam body 1, and the bottom is connected to the upper surfaces of the two mounting brackets 2. Specifically, the adapter seat 3 is installed on the two mounting brackets 2 located on both sides of the beam body 1 through the through-connector 4, and is used to cooperate with the through-connector 4 to complete the installation of the bridge housing mounting seat 5.

[0051] In this embodiment, the through-connecting member 4 is disposed on both sides of the mounting bracket 2 , and one end of the through-connecting member 4 sequentially penetrates the mounting bracket 2 and the adapter seat 3 , and extends to above the adapter seat 3 .

[0052] Among them, the bridge housing mounting seat 5 is symmetrically arranged on both sides of the upper surface of the adapter seat 3, and is sleeved on the through-connector 4, for being welded together with the bridge housing body 6, and the installation of the bridge housing body 6 and the beam body 1 is completed by locking the through-connector 4.

[0053] It should be noted that the through-connecting member 4 is in a locked state, so that the axle housing mounting seat 5, the adapter seat 3 and the mounting bracket 2 are fastened together.

[0054] It should also be noted that, in the present embodiment, one end of the axle housing mounting seat 5 can overlap with the upper surface of the adapter seat 3, so that when the through-connector 4 is in a locked state, the axle housing mounting seat 5 can be fixed and limited.

[0055] In this embodiment, the bridge housing body 6 is located between the two bridge housing mounting seats 5, and is welded to the two bridge housing mounting seats 5, and a gap is reserved with the upper surface of the adapter seat 3. Accordingly, the bridge housing body 6 and the beam body 1 can be connected non-contactly, that is, the two are auxiliaryly connected through the bridge housing mounting seat 5, the adapter seat 3, the mounting bracket 2 and the through-connector 4 as an intermediate medium. Therefore, when the bridge housing body 6 and the beam body 1 are subjected to longitudinal impact force, the force can be dispersed on the bridge housing mounting seat 5, the adapter seat 3 and the mounting bracket 2. Compared with the method in the prior art where the longitudinal impact force directly acts on the contact surface between the bridge housing body 6 and the beam body 1, cracks on the upper and lower contact surfaces between the bridge housing body 6 and the beam body 1 can be avoided, thereby achieving the purpose of extending the service life of the bridge housing body 6 and the beam body 1.

[0056] In this embodiment, the axle housing mounting seat 5 is welded to the middle part of the axle housing body 6, so that when the axle housing body 6 is subjected to longitudinal impact force, the force can be dispersed on the axle housing mounting seat 5 more evenly, further extending the service life of the device.

[0057] In other embodiments, the adapter seat 3 is extended along the length direction of the beam body 1 and along a direction perpendicular to the length direction of the beam body 1 to form a first extension portion 31 and a second extension portion 32 .

[0058] like Figure 1 As shown, the first extension portion 31 and the second extension portion 32 are respectively formed with installation grooves for installing the longitudinal thrust rod 7 and the vertical pull rod 8, so that both the longitudinal thrust rod 7 and the vertical pull rod 8 can be installed on the adapter seat 3. Compared with the method of installing the longitudinal thrust rod 7 and the vertical pull rod 8 on the beam body 1 through the connecting seat in the prior art, the number of accessories welded on the surface of the beam body 1 can be effectively reduced, so as to further extend the service life of the beam body 1.

[0059] In this embodiment, in order to meet the actual application requirements, the bridge housing body 6 is arranged to be inclined to meet the placement requirements of the driving bevel gear of the transmission shaft in the bridge housing body 6 .

[0060] The length direction of the through-connecting member 4 is parallel to the end surface of the bridge housing mounting seat 5 close to the bridge housing body 6, and is perpendicular to the horizontal center line of the bridge housing body 6. Figure 3As shown by the dotted lines L1 and L2 , this arrangement ensures that the overall structure can meet the installation requirements of the bridge housing body 6 .

[0061] It should be noted that, in the present embodiment, the adapter seat 3 is cast and formed according to the inclination installation requirements of the bridge housing body 6 when leaving the factory.

[0062] In a further embodiment, a specific mounting bracket 2 is also provided to better meet the locking requirements of the through-connector 4 .

[0063] Specifically, the mounting bracket 2 includes a first connecting plate 21 and a second connecting plate 22 connected from top to bottom by a fixing member 23 .

[0064] The first connecting plate 21 is welded to the outer wall of the beam body 1 , and the end of the through-connector 4 sequentially penetrates the second connecting plate 22 and the first connecting plate 21 .

[0065] It should be noted that the side of the second connecting plate 22 away from the first connecting plate 21 is parallel to the horizontal center line of the bridge housing body 6, so that the through-connector 4 can fit with the second connecting plate 22 to ensure that the through-connector 4 and the second connecting plate 22 are always fitted together without deviation.

[0066] In addition, the through-connector 4 includes a threaded rod 41 and a nut 42 .

[0067] One end of the threaded rod 41 passes through the mounting bracket 2 , the adapter seat 3 and the bridge housing mounting seat 5 in sequence.

[0068] The nut 42 is threadedly mounted on the outer wall of the threaded rod 41 and can be rotated to fit tightly against the upper surface of the axle housing mounting seat 5, that is, the axle housing mounting seat 5 is locked by rotating the nut 42, and the connection and fixation of the mounting bracket 2 and the adapter seat 3 are correspondingly completed.

[0069] In this embodiment, four groups of through-connecting members 4 are provided, and are symmetrically arranged in pairs on both sides of the beam body 1 to improve the installation stability of the bridge housing mounting seat 5.

[0070] In a further embodiment, gaskets are provided between the axle housing mounting seat 5 and the nut 42 and between the axle housing mounting seat 5 and the adapter seat 3 to enhance stability.

[0071] Embodiment 2

[0072] like Figure 4As shown, the main difference between this embodiment and the first embodiment is that the second connecting plate 22 and the fixing member 23 are further limited, and the adapter seat 3 and the first connecting plate 21 are partially adjusted so that the angle of the through-connecting member 4 can be adjusted according to the inclination requirements of the bridge housing body 6 to meet the application requirements, thereby achieving a greater applicability.

[0073] Specifically, the second connecting plate 22 is disposed outside the axle housing body 6 and can swing relative to the axle housing body 6 .

[0074] Among them, during the swinging process of the second connecting plate 22, the side of the second connecting plate 22 away from the first connecting plate 21 is always perpendicular to the length direction of the through-connecting piece 4, and then when the second connecting plate 22 swings, you don’t need to adjust the angle of the through-connecting piece 4 accordingly. Correspondingly, since the bridge housing mounting seat 5 is mounted on the through-connecting piece 4, the angle of the bridge housing mounting seat 5 is also adjusted accordingly, thereby satisfying the inclination angle requirement of the bridge housing body 6 located between the two bridge housing mounting seats 5, and the applicability is stronger.

[0075] Specifically, the fixing member 23 includes a hinge rod 231 and a telescopic rod 232 , so that a deformable quadrilateral structure is formed between the first connecting plate 21 , the second connecting plate 22 and the fixing member 23 .

[0076] Among them, one end of the hinged rod 231 is fixedly connected to the first connecting plate 21, and the other end is hinged to one side of the second connecting plate 22. One end of the telescopic rod 232 is connected to the first connecting plate 21, and the other end is hinged to the other side of the second connecting plate 22. When the telescopic rod 232 is extended or retracted, the second connecting plate 22 is driven to swing to change the inclination angle of the second connecting plate 22, thereby completing the adjustment of the angles of the through-connecting member 4 and the axle housing mounting seat 5 in turn, so as to meet the installation of the axle housing body 6 with different inclination angle requirements, and the adaptability is stronger.

[0077] In this embodiment, a mounting bracket 2 including a first connecting plate 21, a second connecting plate 22 and a fixing member 23 is provided, and the fixing member 23 includes a hinged rod 231 and a telescopic rod 232, so that a deformable quadrilateral structure is formed around the first connecting plate 21, the second connecting plate 22, the hinged rod 231 and the telescopic rod 232, so that when the telescopic rod 232 is extended or retracted, the angle formed between the second connecting plate 22 and the horizontal plane can be adjusted, thereby correspondingly completing the adjustment of the angle of the through-connecting member 4, so as to be suitable for the installation of the bridge housing body 6 with different inclination angle requirements, thereby achieving the purpose of greater applicability.

[0078] It should be noted that, in this embodiment, the telescopic rod 232 can be set as an electric telescopic rod or a telescopic rod 232 including a fixed threaded barrel and a threaded screw, one end of which is hinged to the second connecting plate 22 through a hinge seat. The threaded screw can rotate relative to the hinge seat to complete the telescopic adjustment function.

[0079] It should be particularly noted that both the first connecting plate 21 and the adapter seat 3 are provided with waist-shaped grooves for providing movement compensation for the through-connecting member 4 in the horizontal direction.

[0080] Among them, through the above-mentioned arrangement, the adapter seat 3 proposed in this embodiment has certain inconveniences compared with the adapter seat 3 proposed in Example 1, that is, since the bridge housing mounting seat 5 will change its angle relative to the adapter seat 3, the adapter seat 3 cannot fulfill the requirement of overlapping support for the bridge housing mounting seat 5, so the through-connecting piece 4 is further limited here to complete the positioning support of the bridge housing mounting seat 5.

[0081] Specifically, the through-connector 4 includes a threaded rod 41 and two nuts 42 . The axle housing mounting seat 5 is sleeved on the threaded rod 41 and can be located between the two nuts 42 . The positioning and support of the axle housing mounting seat 5 is completed by the two nuts 42 .

[0082] Preferably, the thread directions of the two nuts 42 are opposite to each other, so as to further improve the stability of the positioning support of the axle housing mounting seat 5 .

[0083] In a further embodiment, a through hole matching the through connector 4 is provided on the second connecting plate 22, so that one end of the through connector 4 (i.e., one end of the threaded rod 41) is always in contact with the side of the second connecting plate 22 away from the first connecting plate 21, so that when the second connecting plate 22 is deflected, the through connector 4 can be synchronously driven to deflect, so as to complete the angle adjustment of the bridge housing mounting seat 5, so as to be suitable for the installation of the bridge housing body 6 with different inclination angle requirements, thereby achieving the purpose of greater applicability.

[0084] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
