Description

Technical Field

[0001] This utility model relates to the field of balance shaft housing technology, and specifically to a lightweight balance shaft housing. Background Technology

[0002] The balance shaft is an important component of heavy-duty vehicles. Its main function is to transmit all forces and torques between the wheels and the vehicle body. It bears the mass and load of the vehicle body as well as the dynamic load of the wheels under various working conditions. The balance shaft's spindle, crossbeam, and bracket are subjected to impact loads and alternating loads for a long time.

[0003] Chinese patent CN219911590U discloses a balance shaft housing. By setting up a balance shaft housing, it utilizes the design of a stop structure to achieve contact between the outer surface of the nut and the stop, thereby achieving the purpose of restricting the movement of the nut, ensuring the fixing effect and connection efficiency between the shaft housing and the leaf spring, and facilitating the subsequent use of the shaft housing.

[0004] Although the above solution restricts the movement of the nut by adding a stop, the balance shaft housing itself is relatively bulky and heavy, which does not meet the requirements of automotive lightweighting.

[0005] Therefore, this invention provides a lightweight balance shaft housing to solve the above problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a lightweight balance shaft housing to solve the problem that the balance shaft housing itself is relatively bulky and heavy, and cannot meet the requirements of automotive lightweighting.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A lightweight balance shaft housing includes a main tube, with support frames fixedly connected to both sides of the main tube. Each of the two support frames has a weight-reducing groove. A reinforcing rod arranged in a circumferential array is provided between the two support frames, and the two ends of the reinforcing rod are fixedly connected to the two support frames respectively. The support frames also have heat dissipation holes, which are connected to the weight-reducing grooves. A reinforcing component is provided on the main tube.

[0009] Preferably, auxiliary components are fixedly connected to the two support frames on opposite sides, and sealing grooves are provided on both auxiliary components, which are connected to the main pipe.

[0010] Preferably, the auxiliary component has an inclined groove.

[0011] Preferably, each of the two support frames is fixedly connected to a mounting plate, and each of the two mounting plates is provided with mounting holes.

[0012] Preferably, the main tube, the support frame, and the auxiliary components are integrally formed.

[0013] Preferably, each of the weight-reducing grooves is fixedly connected with a reinforcing rib.

[0014] Preferably, the two support frames are provided with curved chamfers on the sides that are far apart from each other.

[0015] Preferably, each of the reinforcing rods has a groove.

[0016] Preferably, the reinforcement component includes a reinforcement ring fixedly connected to the middle section of the main pipe, two connecting blocks are fixedly connected to the reinforcement ring, and a connecting rod is fixedly connected to each of the two connecting blocks, with the end of the connecting rod away from the connecting block fixedly connected to the support frame.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. By creating weight-reduction grooves on the support frame, the weight of the support frame is reduced by removing some material, meeting the requirements of automotive lightweighting. Furthermore, the heat dissipation holes on the support frame are connected to the weight-reduction grooves, allowing external air to flow within the weight-reduction grooves and forming air convection. This effectively dissipates the heat generated during the operation of the balance shaft, achieving lightweighting while improving heat dissipation performance and preventing the balance shaft from being affected by excessive temperature, thus extending its normal operation and service life.

[0019] 2. By setting grooves on the reinforcing rods, the weight is further reduced. At the same time, the connection stability between the main pipe and the support frame is enhanced by the circumferential array of reinforcing rods and the X-shaped connecting rod structure. By adopting an integrated molding process for the main pipe, support frame and auxiliary parts, the splicing nodes are reduced while the overall structural strength is improved. This avoids the stress concentration problem caused by the connection parts of the traditional split structure, and ensures reliable mechanical performance under the lightweight design.

[0020] 3. By setting mounting plates and mounting holes at both ends of the two support frames, it supports multi-position bolt fixing, adapts to different installation scenarios, and improves installation flexibility. The arc-shaped chamfer design reduces the risk of the support frame damaging other components and optimizes assembly compatibility. It also utilizes the reinforcing ring and connecting rod in the reinforcement component to form a three-dimensional support structure. When subjected to impact loads and alternating loads, it can disperse the stress in the middle section of the main tube and improve the durability of the balance shaft housing under complex working conditions, meeting the requirements of heavy-duty vehicles for high-reliability components.

[0026] The following will refer to the attached reference. Figures 1 to 4 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0027] A lightweight balance housing, such as Figure 1-4 As shown, the device includes a main pipe 1, with support frames 2 fixedly connected to both sides of the main pipe 1. Auxiliary components 3 are fixedly connected to the opposite sides of the two support frames 2. Each of the two auxiliary components 3 has a sealing groove 4, which is connected to the main pipe 1. The volume of the sealing groove 4 is larger than the inner diameter of the main pipe 1. When the shaft is installed inside the main pipe 1, bearings, sealing rings, and other structures can be installed in the sealing groove 4 to seal the connection between the main pipe 1 and the bearing.

[0028] The auxiliary component 3 has a slanted groove 5, which facilitates the installation of components on the auxiliary component 3 later.

[0029] Mounting plates 8 are fixedly connected to both support frames 2. Mounting holes 9 are provided on both mounting plates 8. Bolts are installed in the mounting holes 9 to fix the support frame 2 in a suitable position. Mounting plates 8 are provided at both ends of each support frame 2 to facilitate the fixation of the support frame 2 in multiple positions.

[0030] The main pipe 1, support frame 2 and auxiliary parts 3 are integrally formed. The overall structure has high strength due to the integrally formed main pipe 1, support frame 2 and auxiliary parts 3. The mounting plate 8 can also be integrally formed with the main pipe 1, support frame 2 and auxiliary parts 3.

[0031] Both support frames 2 have rounded chamfers on their opposite sides to reduce damage to the rest of the structure caused by the support frames 2.

[0032] Both support frames 2 are provided with weight-reducing grooves 6 to reduce the weight of the support frame 2. Each weight-reducing groove 6 is fixedly connected with a reinforcing rib, which can improve the structural strength of the support frame 2. A reinforcing rod 10 arranged in a circular array is provided between the two support frames 2, and the two ends of the reinforcing rod 10 are fixedly connected to the two support frames 2 respectively. The reinforcing rod 10 enhances the stability of the connection between the two support frames 2. Each reinforcing rod 10 is provided with a groove 11 to further reduce the weight of the reinforcing rod 10.

[0033] The support frame 2 is also provided with heat dissipation holes 7, and the heat dissipation holes 7 are connected to the weight reduction groove 6. The heat dissipation holes 7 allow external air to flow in the weight reduction groove 6, which reduces the weight of the support frame 2 while ensuring heat dissipation of the support frame 2.

[0034] The main pipe 1 is provided with a reinforcing component, which includes a reinforcing ring 12 fixedly connected to the middle section of the main pipe 1. Two connecting blocks 13 are fixedly connected to the reinforcing ring 12. Each of the two connecting blocks 13 is fixedly connected with a connecting rod 14. The end of the connecting rod 14 away from the connecting block 13 is fixedly connected to the support frame 2. The two sets of connecting rods 14 are arranged in an X shape on the connecting blocks 13 to form a reinforcing structure to improve the stability of the connection between the main pipe 1 and the support frame 2.

[0035] The reinforcing ring 12 and the connecting rod 14 form a three-dimensional support structure, which can disperse the stress in the middle section of the main tube 1 when subjected to impact loads and alternating loads, and improve the durability of the balance shaft housing under complex working conditions.
