[0020] Beneficial effects:

[0021] The harvester drive axle housing assembly itself not only bears the load and transmits force, but also provides mounting support for other components on the chassis. The axle housing body is the core component of the harvester drive axle housing assembly. The axle housing body provided in this application includes an integrally manufactured intermediate section, transition section, and side section to reduce welding at connection points, thereby improving the overall integrity and strength of the axle housing body.

[0022] Other features and advantages of the embodiments of this application will be described in detail in the following detailed description section. Attached Figure Description

[0027] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0028] The terminology of the harvester and its drive axle housing assembly 100 according to this application is described below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, a specific embodiment of this application provides a harvester drive axle housing assembly 100, which includes a housing body and multiple mounting components. The housing body is integrally manufactured and includes a middle section 1, a transition section 2, and a side section 3. The central axes of the middle section 1 and the side section 3 have a height difference. The transition section 2 connects the mutually oriented ends of the middle section 1 and the side section 3. Multiple connecting parts are formed on the housing body, and multiple mounting components are connected to the housing body. Both the connecting parts and the mounting components are used to connect with the functional components of the harvester.

[0030] The drive axle housing assembly 100 is a major load-bearing component on the harvester chassis, and it also connects to other functional components on the chassis to provide installation support. In other words, the drive axle housing assembly 100 requires high strength. The drive axle housing assembly 100 includes a housing body and multiple mounting components connected to it. The housing body is the main load-bearing part of the drive axle housing assembly 100. Therefore, increasing the strength of the housing body alone can improve the strength of the drive axle housing assembly 100, ensuring its load-bearing, force transmission, and installation support functions. The housing body is designed according to installation requirements, consisting of a middle section 1, a transition section 2, and a side section 3. In this application, by integrally manufacturing the middle section 1, transition section 2, and side section 3 of the housing body, the connection structure between them is eliminated, thereby improving the overall integrity of the housing body and thus its strength.

[0031] In addition to ensuring the support function of the drive axle housing assembly 100 for other functional components by increasing its strength, the same support function can be achieved by increasing the connection strength between the drive axle housing assembly 100 and other functional components. In the prior art, connectors are used to connect other functional components to the housing body, meaning the connectors are manufactured separately from both the other functional components and the housing body. In this application, some connectors are integrally manufactured with the housing body to form multiple connecting parts on the housing body, thereby increasing the connection strength between the other functional components and the housing body. Other connectors that cannot be integrally manufactured with the housing body are the mounting parts in this application. These mounting parts still need to be manufactured separately from the housing body, but the connection strength between some functional components and the housing body is effectively strengthened.

[0032] It is evident that the drive axle housing assembly 100 in this application can ensure the realization of the load-bearing, force transmission, and installation support functions of the drive axle housing assembly 100 from both its own strength and the connection strength between itself and other functional components, thereby improving the reliability of the drive axle housing assembly 100.

[0033] Meanwhile, by eliminating the connection structure between the intermediate section 1, the transition section 2 and the side section 3, the connection process between the intermediate section 1, the transition section 2 and the side section 3 can also be eliminated, thereby accelerating the processing speed of the drive axle housing assembly 100.

[0034] It should be noted that, in the description of this disclosure, unless otherwise stated, the terms "upper," "lower," "left," "right," "front," "rear," "inner," and "outer," etc., indicating orientation or positional relationships, are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure. When the absolute position of the described object changes, the relative positional relationship may also change accordingly. For ease of description, the "front-back direction," "left-right direction," and "up-down direction" in the specific embodiments of this application are all as shown by the arrow directions in the accompanying drawings.

[0035] In some embodiments, the intermediate section 1 is located above the side section 3. Since the intermediate section 1 and the side section 3 connect to different functional components, they are arranged according to the position of each functional component to achieve the connection between each functional component and the bridge housing body and to avoid interference between the functional components.

[0036] In some embodiments, the transition section 2 is a stepped structure, the first end of the transition section 2 is higher than the second end of the transition section 2, the first end of the transition section 2 is connected to the middle section 1, and the second end of the transition section 2 is connected to the side section 3.

[0037] Specifically, the first end of the transition section 2 is located above the second end of the transition section 2. The upper and lower surfaces of the transition section 2 are both stepped to achieve the transition connection between the middle section 1 and the side section 3, and to form multiple clearance gaps on the transition section 2, thereby avoiding interference between the functional components above the bridge shell body and the transition section 2.

[0038] Furthermore, the steps of the stepped structure are curved steps to reduce the sharp corners on transition section 2, thereby reducing stress concentration on transition section 2. Specifically, the upper surface of transition section 2 forms several curved protrusions and several curved concave parts, and the curved protrusions and curved concave parts are alternately connected in sequence; the lower surface of transition section 2 forms several curved protrusions and several curved concave parts, and the curved protrusions and curved concave parts are alternately connected in sequence; the arrangement order of the curved protrusions and curved concave parts on the upper surface of transition section 2 is consistent with the arrangement order of the curved protrusions and curved concave parts on the lower surface of transition section 2.

[0039] In the exemplary embodiment of this application, there are two side segments 3 and two transition segments 2. The two transition segments 2 are respectively connected to the two ends of the middle segment 1. The middle segment 1 and the side segments 3 both extend in the left and right direction. The transition segment 2 connected to the left end of the middle segment 1 is the left transition segment 2, the transition segment 2 connected to the right end of the middle segment 1 is the right transition segment 2, the side segment 3 connected to the left transition segment 2 is the left side segment 3, and the side segment 3 connected to the right transition segment 2 is the right side segment 3.

[0040] Preferably, the left transition section 2 and the right transition section 2 are arranged symmetrically, and the left side section 3 and the right side section 3 are arranged symmetrically, so as to give the bridge shell body better structural integrity and aesthetics. It should be noted that the length and shape of the middle section 1, the transition section 2 and the side section 3 can be adaptively adjusted according to specific usage requirements, and this adjustment method is well known to those skilled in the art.

[0041] Preferably, the axle housing body is provided with multiple weight reduction holes 4 to reduce the weight of the axle housing body, thereby meeting the lightweight design requirements of the drive axle housing assembly 100.

[0042] More preferably, the size of each weight-reducing hole 4 conforms to the design standard, and multiple weight-reducing holes 4 are arranged at intervals in the left and right directions. The leftmost weight-reducing hole 4 is located at the left end of the left transition section 2, and the rightmost right weight-reducing hole 4 is located at the right end of the transition section 2, thereby achieving weight reduction of the entire axle housing body, and thus making the axle housing body homogeneous and strong enough while meeting the lightweight design requirements.

[0043] Specifically, the weight reduction hole 4 penetrates the main body of the bridge housing in the vertical direction. Some of the weight reduction holes 4 can also be used to avoid interference between functional components and the main body of the bridge housing or to insert wiring.

[0044] It should be noted that the weight-reducing groove, which plays the same role as the weight-reducing hole 4, is also within the scope of protection of this application.

[0045] In an exemplary embodiment of this application, the axle housing body has a connecting portion for connecting to the wheel-side reducer, a connecting portion for connecting to the frame, and a connecting portion for connecting to the gearbox; the axle housing body is connected to a mounting member for mounting a brake, a mounting member for fixing the cutting table cylinder, and a mounting member for fixing the handbrake cable, wherein the wheel-side reducer, frame, gearbox, brake, cutting table cylinder, and handbrake cable are all common functional components.

[0046] It should be noted that, in order to distinguish between the various connecting parts and the various mounting parts, the connecting part used to connect with the wheel-side reducer is the wheel-side reducer connecting plate 5; the connecting part used to connect with the frame is the frame support seat 6; the connecting part used to connect with the gearbox is the gearbox connecting plate 7; the mounting part used to install the brake is the brake mounting plate 8; the mounting part used to fix the cutting table cylinder is the cylinder bracket 9; and the mounting part used to fix the handbrake cable is the handbrake fixing seat 10.

[0047] In some embodiments, there are two edge reduction connecting discs 5. One edge reduction connecting disc 5 is located at the left end of the left side segment 3 and is integrally formed with the left side segment 3. The other edge reduction connecting disc 5 is located at the right end of the right side segment 3 and is integrally formed with the right side segment 3. The right end face of the left edge reduction connecting disc 5 is attached to the left end face of the left end of the left side segment 3, and the left end face of the right edge reduction connecting disc 5 is attached to the right end face of the right end of the right side segment 3.

[0048] Preferably, a weight-reducing groove is formed at the left end of the left side segment 3, with the groove opening facing left. The side weight-reducing connecting plate 5 closes the groove opening, and the groove opening end of the weight-reducing groove is in contact with the side weight-reducing connecting plate 5. The cross-sectional area of ​​the groove wall near the groove opening is larger than the cross-sectional area of ​​the groove wall near the bottom of the groove, thereby increasing the contact area between the left side segment 3 and the side weight-reducing connecting plate 5 while providing the weight-reducing groove. Similarly, a weight-reducing groove is formed at the right end of the right side segment 3, with the groove opening facing right. The side weight-reducing connecting plate 5 closes the groove opening, and the groove opening end of the weight-reducing groove is in contact with the side weight-reducing connecting plate 5. The cross-sectional area of ​​the groove wall near the groove opening is larger than the cross-sectional area of ​​the groove wall near the bottom of the groove, thereby increasing the contact area between the right side segment 3 and the side weight-reducing connecting plate 5 while providing the weight-reducing groove.

[0049] In some embodiments, the frame support 6 and the top of the side section 3 are integrally manufactured.

[0050] In some embodiments, the cylinder bracket 9 includes two cylinder lugs arranged at intervals in the left-right direction. The two cylinder lugs are parallel to each other and the lug holes on the two cylinder lugs are arranged coaxially, thereby improving the accuracy of the lug holes on the two cylinder lugs.

[0051] In some embodiments, a protrusion 11 is formed on the front side of the intermediate section 1, the protrusion 11 extends forward, and the gearbox connecting plate 7 is disposed at the lower end of the protrusion 11 and is integrally formed with the protrusion 11.

[0052] Specifically, the protrusion 11 is a trapezoidal plate structure, and there are multiple protrusions 11. The lower end faces of multiple protrusions 11 together form the same gearbox connecting plate 7, so as to increase the connection strength between the gearbox connecting plate 7 and the intermediate section 1 and the strength of the gearbox connecting plate 7, thereby ensuring the installation support function of the axle housing body for the gearbox.

[0053] Furthermore, a protrusion 11 is also formed on the rear side of the intermediate section 1 and the protrusion 11 extends rearward. The gearbox connecting plate 7 is provided at the lower end of the protrusion 11 and is integrally formed with the protrusion 11.

[0054] Preferably, a reinforcing rib is provided at the connection between the protrusion 11 and the gearbox connecting plate 7.

[0055] In some embodiments, the gearbox connecting plate 7 protrudes to the left from the protrusion 11, and the handbrake fixing seat 10 is connected to the left end of the gearbox connecting plate 7; the brake mounting plate 8 is connected to the side section 3.

[0056] It should be noted that the connection methods between the mounting components and the main body of the bridge housing include welding, bolting, and riveting, and all of the above connection methods are within the scope of protection of this application.

[0057] In some embodiments, the side reduction connecting plate 5, the frame support 6, and the brake mounting plate 8 are all formed with clearance grooves to avoid interference between the functional components and the drive axle housing assembly 100, so as to facilitate the connection between the functional components and the drive axle housing assembly 100.

[0058] A specific embodiment of this application also provides a harvester, including the harvester drive axle housing assembly 100 as described above. Since the harvester employs all embodiments of the drive axle housing assembly 100, it possesses all the beneficial effects of the drive axle housing assembly 100.
