Description

Technical Field

[0001] The utility model relates to the technical field of mechanical assembly process equipment, in particular to a fixing auxiliary device for storing a truck axle integrated wheel hub bearing assembly. Background Art

[0002] At present, the wheel hub assembly of the truck axle mainly includes the wheel hub, the integrated wheel hub bearing assembly, the wheel hub bolts and the wheel hub oil seal and other parts. Among them, the integrated wheel hub bearing assembly consists of the inner wheel hub bearing (divided into the outer ring and inner ring assembly of the bearing), the outer wheel hub bearing (divided into the outer ring and inner ring assembly of the bearing) and the middle spacer sleeve. The various parts of the integrated wheel hub bearing assembly need to be assembled and used as a set, and are not interchangeable and cannot be mixed. During the assembly of the wheel hub assembly, the outer ring of the inner wheel hub bearing and the outer ring of the outer wheel hub bearing have been press-fitted into the bearing hole of the wheel hub by interference fit. After the assembly is completed, the corresponding inner ring assembly of the inner wheel hub bearing, the inner ring assembly of the outer wheel hub bearing and the middle spacer sleeve are placed in the outer ring, and finally placed on the special wheel hub assembly storage rack.

[0003] Since the bearing inner ring assembly and the middle spacer sleeve are loosely placed with the bearing outer ring that has been pressed onto the wheel hub, it is not conducive to storage and transportation. A fixing aid is needed to quickly and conveniently combine the various components of the wheel hub bearing assembly into a whole. Traditionally, the integrated wheel hub bearing assembly is stored and fixed with nylon cable ties. The cable ties pass through the inner holes of the bearing inner ring assembly and the middle spacer sleeve, bypass the outer edge of the wheel hub, and one end of the cable tie is inserted into the square groove at the other end of the cable tie for fixing. The advantages of this solution are low cost and good versatility. The disadvantages are that the contact posture between the wheel hub inner ring assembly and the outer ring is not good and is easy to bump into. The nylon cable ties are difficult to recycle and cannot be reused. The operation is time-consuming and troublesome. Utility Model Content

[0011] Among them, the connecting shaft includes a connecting section located at one end away from the fixed baffle, and a connecting hole for the connecting section to pass through is opened on the movable baffle, and both ends of the connecting hole are through-connected. The cross-sections of the connecting section and the connecting hole are non-circular and adapted to each other. When the connecting section passes through the connecting hole, the movable baffle is fitted with the end face of the inner bearing inner ring assembly, and the movable baffle can rotate around the axis of the connecting shaft.

[0012] Preferably, the connecting shaft includes a main body section located between the connecting section and the fixed baffle, the main body section has a circular cross-section, and in the axial direction of the connecting shaft, the projection of the main body section covers the projection of the connecting section, and a limiting hole coaxial with the connecting hole is opened on the movable baffle at one end of the connecting hole, the limiting hole has a circular cross-section and an inner diameter is the same as the inner diameter of the main body section, the connecting shaft also includes a transition section located between the connecting section and the main body section, the transition section has a circular cross-section and a diameter no greater than a diameter of an inscribed circle of the cross-sectional figure of the connecting hole, and the length of the transition section is greater than the axial length of the connecting hole and less than the sum of the axial length of the connecting hole and the axial length of the limiting hole.

[0013] Preferably, a eccentric weight is connected to the movable baffle, which is suitable for causing the movable baffle to rotate around the axis of the connecting shaft through the gravity of the eccentric weight when the connecting section passes through the connecting hole, until the projections of the connecting hole and the connecting section on the axial direction of the connecting shaft do not overlap.

[0014] Preferably, the support structure includes two support columns connected to the fixed baffle, and when the two support columns penetrate into the inner hole of the outer bearing inner ring assembly, the two support columns respectively contact the inner walls on opposite sides of the inner hole of the outer bearing inner ring assembly.

[0017] Preferably, the support column is cylindrical and its axis is parallel to the connecting axis.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0019] 1. The present application sets a fixed baffle, a movable baffle and a connecting shaft. When the fixed baffle is fitted with the end face of the inner ring assembly of the outer bearing, the supporting structure penetrates into the inner hole of the inner ring assembly of the outer bearing to limit the fixed baffle from moving relative to the outer bearing inner ring assembly along the radial direction of the inner ring assembly of the outer bearing, thereby limiting the radial movement of the inner ring assembly of the outer bearing relative to the fixed baffle through the supporting structure. At this time, the connecting shaft passes through the inner hole of the wheel hub bearing assembly; then, the movable baffle is connected to the connecting shaft. When connecting the movable baffle, the posture of the movable baffle is adjusted so that the connecting section of the connecting shaft can pass through the connecting hole, thereby the movable baffle is sleeved on the connecting shaft. After the connecting section passes through the connecting hole, the movable baffle is fitted with the end face of the inner ring assembly of the inner bearing. At this time, the movable baffle and the fixed baffle are clamped at both ends of the wheel hub bearing assembly in cooperation. The clamping force along the axial direction of the wheel hub bearing assembly is applied through the fixed baffle and the movable baffle, so that the various components of the wheel hub bearing assembly are combined into one. The wheel hub inner ring assembly and the outer ring are integrated and fixed, and the contact posture between the wheel hub inner ring assembly and the outer ring is good and not easy to bump; because the cross-section of the connecting hole and the connecting section is non-circular, the connecting section can only pass through the connecting hole when the movable baffle is in a specific position when the movable baffle is rotated. When the baffle and the end face of the inner ring assembly of the inner bearing are fitted, the movable baffle is rotated until the projections of the connecting hole and the connecting section in the axial direction of the connecting shaft do not overlap. At this time, the movable baffle is restricted by the connecting section to move away from the wheel hub bearing assembly, so that the movable baffle remains connected to the connecting shaft and cooperates with the fixed baffle to clamp and fix the wheel hub bearing assembly. When it needs to be removed, the movable baffle is rotated until the projections of the connecting hole and the connecting section in the axial direction of the connecting shaft overlap, so that the connecting section can pass through the connecting hole to remove the movable baffle, and the operation is simple and convenient; when the wheel hub bearing assembly is fixed by the fixing auxiliary tool of the present application, the contact posture between the wheel hub inner ring assembly and the outer ring is good, it is easy to use, and can be reused;

[0020] 2. The present application provides a eccentric weight on the movable baffle. When the movable baffle is connected to the connecting shaft and clamps the wheel hub bearing assembly with the fixed baffle, the movable baffle rotates around the axis of the connecting shaft under the action of the gravity of the eccentric weight until the projections of the connecting hole and the connecting section in the axial direction of the connecting shaft do not overlap. At this time, the movable baffle cannot be detached from the connecting shaft and remains in this state to prevent the movable baffle from rotating away from the connecting shaft when transporting the wheel hub bearing assembly.

[0033] Reference Figure 1-5As shown, an embodiment of the present application provides a fixing aid for storing a wheel hub bearing assembly integrated with a truck axle, which includes a fixed baffle 1, a movable baffle 3 and a connecting shaft 2. The fixed baffle 1 is used to fit the end face of the outer bearing inner ring assembly. A supporting structure is provided on the fixed baffle 1. The supporting structure is used to penetrate into the inner hole of the outer bearing inner ring assembly to limit the movement of the fixed baffle 1 relative to the outer bearing inner ring assembly along the radial direction of the outer bearing inner ring assembly; one end of the connecting shaft 2 is fixed to the fixed baffle 1, and the connecting shaft 2 is used to pass through the inner hole of the hub bearing assembly when the fixed baffle 1 fits the end face of the outer bearing inner ring assembly, and the axis of the connecting shaft 2 is parallel to the axis of the inner hole of the hub bearing assembly, and the movable baffle 3 is used to be connected to the connecting shaft 2 when the connecting shaft 2 passes through the inner hole of the hub bearing assembly, and fit the end face of the inner ring assembly of the inner bearing. Among them, the connecting shaft 2 includes a connecting section 21 located at one end away from the fixed baffle 1, and a connecting hole 31 is opened on the movable baffle 3 for the connecting section 21 to pass through. Both ends of the connecting hole 31 are through-connected. The cross-sections of the connecting section 21 and the connecting hole 31 are non-circular and adapted to each other. When the connecting section 21 passes through the connecting hole 31, the movable baffle 3 fits against the end face of the inner bearing inner ring assembly, and the movable baffle 3 can rotate around the axis of the connecting shaft 2.

[0034] When the fixed baffle 1 fits the end face of the outer bearing inner ring assembly, the supporting structure penetrates into the inner hole of the outer bearing inner ring assembly, and the supporting structure limits the radial relative movement of the outer bearing inner ring assembly and the fixed baffle 1. At this time, the connecting shaft 2 passes through the inner hole of the hub bearing assembly; then the movable baffle 3 is connected to the connecting shaft 2. When connecting the movable baffle 3, the posture of the movable baffle 3 is adjusted so that the connecting section 21 of the connecting shaft 2 can pass through the connecting hole 31, and the movable baffle 3 is sleeved on the connecting shaft 2. After the connecting section 21 passes through the connecting hole 31, the movable baffle 3 fits the end face of the inner bearing inner ring assembly. At this time, the movable baffle 3 and the fixed baffle 1 are clamped at both ends of the hub bearing assembly, and the clamping force along the axial direction of the hub bearing assembly is applied by the fixed baffle 1 and the movable baffle 3, so that the various components of the hub bearing assembly are combined into a whole and fixed, and the contact posture between the hub inner ring assembly and the outer ring is good and not easy to bump. Since the cross-sections of the connecting hole 31 and the connecting section 21 are non-circular, the connecting section 21 can pass through the connecting hole 31 only when the movable baffle 3 is in a specific position when rotating. When the movable baffle 3 and the end face of the inner bearing inner ring assembly are fitted, the movable baffle 3 is rotated until the projections of the connecting hole 31 and the connecting section 21 in the axial direction of the connecting shaft 2 do not overlap. At this time, the movable baffle 3 is restricted by the connecting section 21 to move away from the hub bearing assembly, so that the movable baffle 3 remains connected to the connecting shaft 2 and cooperates with the fixed baffle 1 to clamp and fix the hub bearing assembly. When it needs to be removed, the movable baffle 3 is rotated until the projections of the connecting hole 31 and the connecting section 21 in the axial direction of the connecting shaft 2 overlap, so that the connecting section 21 can pass through the connecting hole 31 to remove the movable baffle 3. The operation is simple and convenient.

[0035] Reference Figure 1 and Figure 5As shown, the support structure includes two support columns 11 connected to the fixed baffle 1. When the two support columns 11 penetrate into the inner hole of the outer bearing inner ring assembly, the two support columns 11 respectively contact the inner walls on the opposite sides of the inner hole of the outer bearing inner ring assembly, thereby limiting the relative movement of the fixed baffle 1 and the outer bearing inner ring assembly.

[0036] Reference Figure 1-2 and Figure 5 As shown, further, the length of the fixed baffle 1 is greater than the diameter of the inner hole of the outer bearing inner ring assembly, and the length of the movable baffle 3 is greater than the diameter of the inner hole of the inner bearing inner ring assembly. When the two support columns 11 are in contact with the inner walls on the opposite sides of the inner hole of the outer bearing inner ring assembly respectively, the two ends of the fixed baffle 1 are respectively fitted with the end surfaces on the opposite sides of the inner hole of the outer bearing inner ring assembly, and when the movable baffle 3 is connected to the connecting shaft 2, the two ends are respectively fitted with the end surfaces on the opposite sides of the inner hole of the inner bearing inner ring assembly.

[0037] Reference Figure 1-2 As shown, specifically, the two support columns 11 are spaced apart along the length direction of the fixed baffle 1, the two support columns 11 are respectively close to the two ends of the fixed baffle 1, and the two support columns 11 are symmetrically distributed on both sides of the center in the length direction of the fixed baffle 1, so that when the two support columns 11 contact the inner walls on the opposite sides of the inner hole of the outer bearing inner ring assembly, the two ends of the fixed baffle 1 can respectively fit with the end faces on both sides of the inner hole of the outer bearing inner ring assembly.

[0038] Reference Figure 1 and Figure 5 As shown, further, when the two support columns 11 are in contact with the inner walls on the opposite sides of the inner hole of the outer bearing inner ring assembly respectively, the connecting shaft 2 is coaxial with the hub bearing assembly, and the distance between the connecting hole 31 and the two ends of the movable baffle 3 in the length direction is the same. Specifically, the axis of the connecting shaft 2 is set to be perpendicular to the length direction of the fixed baffle 1, and the connecting shaft 2 is located between the two support columns 11 and has the same spacing with the two support columns 11, so that when the two support columns 11 are in contact with the inner walls on the opposite sides of the inner hole of the outer bearing inner ring assembly respectively, the connecting shaft 2 is coaxial with the hub bearing assembly. In this embodiment, the support column 11 is set to be cylindrical and the axis is parallel to the axis of the connecting shaft 2. When setting the connecting hole 31, the axis of the connecting hole 31 is set to be perpendicular to the length direction of the movable baffle 3, and the distance between the connecting hole 31 and the two ends of the movable baffle 3 in the length direction is the same, so that when the movable baffle 3 is connected to the connecting shaft 2, the two ends can respectively fit with the opposite side end surfaces of the inner hole of the inner bearing inner ring assembly, and when the movable baffle 3 rotates to any angle, it can maintain fit with the opposite side end surfaces of the inner hole of the inner bearing inner ring assembly.

[0039] Through the above arrangement, the fixed baffle 1 and the movable baffle 3 can clamp the wheel hub bearing assembly more stably, and fix the wheel hub bearing assembly more stably.

[0040] Reference Figure 1 and Figure 3 As shown, further, in order to prevent the movable baffle 3 from moving radially relative to the connecting shaft 2 when connected to the connecting shaft 2, the connecting shaft 2 is configured to include a main body section 22 located between the connecting section 21 and the fixed baffle 1, the main body section 22 has a circular cross-section, and in the axial direction of the connecting shaft 2, the projection of the main body section 22 covers the projection of the connecting section 21, and a limiting hole 32 coaxial with the connecting hole 31 is opened on the movable baffle 3 at one end of the connecting hole 31, the limiting hole 32 has a circular cross-section and an inner diameter that is the same as the inner diameter of the main body section 22, and the connecting shaft 2 also includes a transition section 23 located between the connecting section 21 and the main body section 22, the transition section 23 has a circular cross-section and a diameter that is not greater than the diameter of the inscribed circle of the cross-sectional figure of the connecting hole 31, and the length of the transition section 23 is greater than the axial length of the connecting hole 31 and less than the sum of the axial length of the connecting hole 31 and the axial length of the limiting hole 32.

[0041] Reference Figure 1 and Figure 4 As shown, specifically, the connection hole 31 and the limiting hole 32 on the movable baffle 3 are connected. Since the diameter of the connection hole 31 is the same as the diameter of the main section 22, and in the axial direction of the connecting shaft 2, the projection of the main section 22 covers the projection of the connection section 21, that is, the connection section 21 can pass through the limiting hole 32. When the movable baffle 3 is connected to the connecting shaft 2, the connection section 21 first passes through the limiting hole 32 and then passes through the connection hole 31. Due to the setting of the transition section 23, the movable baffle 3 can be moved on the connecting shaft 2 until the connection hole 31 is sleeved outside the transition section 23, so that the connection section 21 can completely pass through the limiting hole 32, so as to limit the movable baffle 3 from being separated from the connecting shaft 2 through the connection section 21. The setting of the length of the transition section 23 enables the main section 22 to partially penetrate into the limiting hole 32 when the connection section 21 passes through the limiting hole 32, so that the movable baffle 3 can be limited to move relative to the connecting shaft 2 in the radial direction through the cooperation of the main section 22 and the limiting hole 32, and the movable baffle 3 can rotate around the connecting shaft 2.

[0042] Through the above arrangement, the stability of the connection between the movable baffle 3 and the connecting shaft 2 can be improved, ensuring that the movable baffle 3 stably fits the end face of the inner bearing inner ring assembly, thereby cooperating with the fixed baffle 1 to stably clamp and fix the hub bearing assembly.

[0043] Reference Figure 1 and Figure 5 As shown, further, when in use, the fixed baffle 1 is fixed to the storage rack of the hub bearing assembly, and the connecting shaft 2 is a fixed part. In order to prevent the movable baffle 3 from rotating and detaching from the connecting shaft 2 due to vibration or the like when transporting the hub bearing assembly, a weight-biasing piece is provided on the movable baffle 3. When the connecting section 21 passes through the connecting hole 31, the movable baffle 3 is rotated around the axis of the connecting shaft 2 by the gravity of the weight-biasing piece until the projections of the connecting hole 31 and the connecting section 21 in the axial direction of the connecting shaft 2 do not overlap.

[0044] Specifically, the eccentric weight piece is a eccentric weight block, which is fixed at one end of the movable baffle 3. When the movable baffle 3 is connected to the connecting shaft 2, the gravity of the eccentric weight block keeps the end of the movable baffle 3 provided with the eccentric weight block below the connecting shaft 2. At this time, the axial projections of the connecting hole 31 and the connecting section 21 on the connecting shaft 2 do not overlap, and the movable baffle 3 cannot be separated from the connecting shaft 2. Under the gravity of the eccentric weight block, the movable baffle 3 can be maintained in this state. It is not easy to rotate too large an angle due to vibration during transportation, resulting in separation from the connecting shaft 2, thereby improving the safety of the wheel hub bearing assembly during transportation.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
