Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and more specifically, to a drive shaft assembly. Background Technology

[0002] An automotive driveshaft is a mechanism that connects two shafts whose axes do not coincide, and enables the two shafts to transmit motion at the same angular velocity. Its function is to transmit the engine's power from the transmission to the car wheels, and to meet the rotation angle requirements of the outer end of the vehicle's driveshaft.

[0003] In some existing automotive driveshaft systems, damage to a portion of the driveshaft makes repair inconvenient and may necessitate replacing the entire driveshaft, resulting in material waste and reduced product efficiency. Therefore, we propose a new driveshaft assembly. Utility Model Content

[0004] To solve the above problems, this utility model provides a drive shaft assembly, which adopts the following technical solution:

[0005] A drive shaft assembly includes a main shaft, with connecting blocks at both ends of the main shaft, universal joints fixedly installed on opposite sides of the two connecting blocks, flanges at opposite ends of the two universal joints, and fixing components between the two connecting blocks and the opposite ends of the main shaft.

[0006] The main spindle includes a second spindle body and first spindle bodies disposed on both sides of the second spindle body, and an assembly assembly is provided between the two first spindle bodies and the second spindle body.

[0007] By adopting the above technical solution, the main shaft of the product is fixed by the first shaft body and the second shaft body through the assembly components, and the universal joint is fixed to both ends of the main shaft through the fixing components. The opposite ends of the two universal joints are provided with flanges to facilitate subsequent connection with components. The first shaft body, the second shaft body and the universal joint are set separately, which facilitates subsequent replacement and maintenance. When a part of the product is damaged, only the damaged part needs to be replaced, which reduces the waste of materials.

[0008] Furthermore, the fixing assembly includes a plug rod fixedly installed on one side of the two connecting blocks, slots matching the plug rods on both sides of the main shaft, screw rods fixedly installed on the opposite ends of the two plug rods, and threaded grooves matching the screw rods on the opposite inner walls of the two slots. The plug rods and the slots on the same side are fixed together by a first bolt.

[0009] By adopting the above technical solution, when installing the universal joint, the worker places the plug rod installed at one end of the universal joint into the slots opened at both ends of the main shaft, and then rotates the universal joint to make the universal joint drive the screw rotate, thereby making the screw engage with the screw groove opened in the slot on the same side, which can play the role of initially fixing the universal joint. Then, by passing the first bolt through the main shaft and engaging with the screw hole opened in the side wall of the plug rod on the same side, the universal joint can be further fixed, which helps to maintain the stability of the assembly of the universal joint and the main shaft.

[0010] Furthermore, the assembly includes an assembly block disposed at one end of two first shafts, and two ends of the second shaft are provided with assembly grooves that match the assembly blocks on the same side. The sidewalls of the two first shafts and the second shafts are provided with multiple assembly plates arranged in a ring array. The sidewalls of the two first shafts and the second shafts are provided with grooves that match the assembly plates on the same side. The assembly plates and the grooves on the same side are fixed together by second bolts.

[0011] By adopting the above technical solution, when the spindle needs to be assembled, the worker will engage the assembly block installed at one end of the first spindle with the assembly slots opened at both ends of the second spindle. Through the cooperation of the assembly block and the assembly slots, the first and second spindles can be positioned and assembled. After the first and second spindles are initially assembled, the worker will place the assembly plate in the groove opened at the opposite end of the first and second spindles, and then fix it with the second bolt to fix the assembled spindle.

[0012] Furthermore, two symmetrically distributed positioning blocks are fixedly installed on the inner side of each assembly plate, and a positioning groove matching the positioning block is opened on the inner wall of the groove on the side away from the assembly plate on the same side.

[0013] By adopting the above technical solution, a positioning block is provided on the inner side of the assembly plate. The positioning block engages with the positioning groove opened in the groove on the same side, which can play the role of positioning the assembly plate and facilitate subsequent fixing.

[0014] Furthermore, stabilizing blocks are fixedly installed on the inner walls of the two opposing sides of the two assembly slots. The opposite ends of the two stabilizing blocks slide through the assembly blocks on the same side, and the opposite ends of the two first shafts are provided with stabilizing slots that match the stabilizing blocks on the same side.

[0015] By adopting the above technical solution, a stabilizing block is provided in the assembly slot. When the assembly block moves into the same side assembly slot, the stabilizing block slides through the same side assembly block and engages with the stabilizing slot opened in the first shaft body, thereby further positioning and stabilizing the first shaft body and the second shaft body, which is convenient for subsequent fixing.

[0016] Furthermore, a protective sleeve is fitted on the side wall of the spindle, and two symmetrically distributed limiting posts are fixedly installed on the inner walls of both ends of the protective sleeve. The side wall of the spindle is provided with limiting holes that match the limiting posts on the same side.

[0017] By adopting the above technical solution, a protective sleeve is fitted on the side wall of the spindle to protect the spindle. The protective sleeve has a limiting post inside, which engages with the limiting hole opened on the side wall of the spindle to position the protective sleeve. The protective sleeve is made of rubber and has a certain deformation capacity, which makes it easy to fit onto the side wall of the spindle.

[0018] In summary, this utility model has the following beneficial technical effects:

[0019] (1) In this utility model, the main shaft is assembled from two first shafts and a second shaft, and the universal joints at both ends of the main shaft are fixed by a fixing component. The universal joints, the first shafts and the second shafts are set separately, which facilitates subsequent replacement and maintenance and helps to reduce material waste.

[0020] (2) In this utility model, the first shaft and the second shaft are fixed together by an assembly component, and the first shaft and the second shaft are fixed together by the insertion of an assembly block, an assembly groove, a stabilizing block and a stabilizing groove, which plays the role of positioning and stabilizing the first shaft and the second shaft, facilitating subsequent fixing, and helping to maintain the stability of the spindle assembly.

[0032] Please see Figure 1-5 A drive shaft assembly includes a main shaft 2, with connecting blocks 3 at both ends of the main shaft 2. Universal joints 4 are fixedly installed on opposite sides of the two connecting blocks 3, and flanges are provided on opposite ends of the two universal joints 4. A fixing assembly is provided between the two connecting blocks 3 and the opposite ends of the main shaft 2. The fixing assembly includes insert rods 31 fixedly installed on opposite sides of the two connecting blocks 3. Slots 211 matching the insert rods 31 on the same side are opened on both sides of the main shaft 2. Screws are fixedly installed on opposite ends of the two insert rods 31. Threaded grooves matching the screws on the same side are opened on the inner wall of the opposite side of the two slots 211. The insert rods 31 and the slots 211 on the same side are fixed together by a first bolt.

[0033] When installing the universal joint 4, the worker places the insert rod 31 installed at one end of the universal joint 4 into the slots 211 opened at both ends of the main shaft 2, and then rotates the universal joint 4 to drive the screw to rotate, so that the screw engages with the screw groove opened in the slot 211 on the same side, which can play the role of initially fixing the universal joint 4. Then, by passing the first bolt through the main shaft 2 and engaging with the screw hole opened on the side wall of the insert rod 31 on the same side, the universal joint 4 can be further fixed, which helps to maintain the stability of the assembly of the universal joint 4 and the main shaft 2.

[0034] The main shaft 2 includes a second shaft body 22 and first shaft bodies 21 disposed on both sides of the second shaft body 22. An assembly assembly is provided between the two first shaft bodies 21 and the second shaft body 22.

The opposite ends of the two stabilizing blocks 222 slide through the assembly blocks 212 on the same side. The opposite ends of the two first shaft bodies 21 are provided with stabilizing grooves that match the stabilizing blocks 222 on the same side.

[0035] When the spindle 2 needs to be assembled, the worker engages the assembly block 212 installed at one end of the first shaft 21 with the assembly slots 221 opened at both ends of the second shaft 22. Through the cooperation of the assembly block 212 and the assembly slots 221, the first shaft 21 and the second shaft 22 can be positioned and assembled. The assembly slots 221 are equipped with stabilizing blocks 222. When the assembly block 212 moves into the same side assembly slot 221, the stabilizing block 222 slides through the same side assembly block 212 and engages with the stabilizing slot opened in the first shaft 21, thereby further positioning and stabilizing the first shaft 21 and the second shaft 22. After the first shaft 21 and the second shaft 22 are initially assembled, the worker places the assembly plate 5 into the groove 6 opened at the opposite end of the first shaft 21 and the second shaft 22, and then fixes it with the second bolt, which can fix the assembled spindle 2.
