Description
Technical Field
[0001] The utility model belongs to the technical field of automobile transmission shafts, and in particular relates to a lightweight aluminum bracket with a water tank for fixing an intermediate transmission shaft assembly of a four-wheel drive vehicle. Background Art
[0002] With the advancement of automobile technology, the application of four-wheel drive models is becoming more and more extensive. Four-wheel drive vehicles transmit power to each wheel through the intermediate drive shaft system to meet the driving needs under complex road conditions. Therefore, the design of the intermediate drive shaft system needs to adapt to the special requirements of four-wheel drive models. With the advancement of automobile technology, the application of four-wheel drive models is becoming more and more extensive. Four-wheel drive vehicles transmit power to each wheel through the intermediate drive shaft system to meet the driving needs under complex road conditions. Therefore, the design of the intermediate drive shaft system needs to adapt to the special requirements of four-wheel drive models. The intermediate drive shaft system is an important part of the automobile transmission system, which directly affects the power transmission efficiency and driving stability of the automobile. Therefore, when designing the intermediate drive shaft system, factors such as transmission efficiency, torque transmission capacity, vibration and noise control need to be fully considered to ensure that the car can maintain good performance under various working conditions.
[0003] The intermediate transmission shaft system needs to withstand large torque and vibration, so it is crucial to choose the right materials and processes. Traditional transmission shafts are usually made of steel, but in recent years, with the application of lightweight materials such as aluminum alloys, the weight of the transmission shaft has been significantly reduced while maintaining sufficient strength and rigidity. In addition, advanced processing technology and heat treatment technology can also help improve the manufacturing accuracy and service life of the transmission shaft.
[0004] Generally, the design of the drive shaft system of four-wheel drive vehicles focuses on reducing vibration, improving transmission efficiency and ensuring structural strength. As an important component of the drive shaft, the intermediate bracket is designed to provide stable support for the drive shaft, while absorbing or reducing the vibration and impact force caused by uneven road surface, and ensuring the stable operation of the transmission system. At present, the aluminum bracket used to fix the intermediate drive shaft assembly of four-wheel drive vehicles has no water tank structure, which has an adverse effect on the economy of the vehicle and increases the cost of the whole vehicle. After four-wheel drive vehicles are on off-road conditions such as gravel roads, sand, snow, and mud, external dust, sand, mud and water are easily accumulated between the intermediate drive shaft assembly and the aluminum bracket. During the movement of the vehicle, the intermediate support of the intermediate drive shaft assembly interferes with foreign matter (sand, mud, etc.) accumulated on the bracket, resulting in deformation of the intermediate support sheet metal bracket, the intermediate support rubber and bearings are affected by external forces for a long time, and the intermediate drive shaft assembly is prone to NVH (noise, vibration and harshness) problems such as abnormal noise, shaking, and roaring, causing customer complaints and adversely affecting the brand image of the OEM.

[0028] In order to further understand the content of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the embodiments are only for explaining the utility model and are not intended to limit it.
[0029] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] The accompanying drawings show various structural schematic diagrams of the embodiments disclosed in the utility model. These figures are not drawn to scale, and some details are magnified and some details may be omitted for the purpose of clear expression. The shapes of various regions and layers shown in the figures and the relative sizes and positional relationships therebetween are only exemplary, and may deviate in practice due to manufacturing tolerances or technical limitations, and those skilled in the art may additionally design regions / layers with different shapes, sizes, and relative positions according to actual needs.
[0031] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0032] A lightweight aluminum bracket with a water tank for fixing an intermediate transmission shaft assembly of a four-wheel drive vehicle, the structure of which is as follows:
[0033] like Figures 1 to 3 As shown, a lightweight aluminum bracket with a water tank for fixing an intermediate transmission shaft assembly of a four-wheel drive vehicle includes an intermediate transmission shaft assembly 1, an intermediate supporting sheet metal bracket 2, a lightweight aluminum bracket 4 and a water tank structure 5. A transmission shaft bearing 3 is provided on the intermediate transmission shaft assembly 1, the intermediate supporting sheet metal bracket 2 is sleeved on the outside of the transmission shaft bearing 3, a plurality of through holes are opened in the middle position of the bottom of the lightweight aluminum bracket 4, and the plurality of through holes constitute the water tank structure 5, and the intermediate supporting sheet metal bracket 2 is installed above the water tank structure 5 of the lightweight aluminum bracket 4.
[0034] The trough structure 5 is an arc-shaped groove, and the diameter of the trough structure 5 is larger than the diameter of the intermediate support sheet metal bracket 2, so a semicircular ring-shaped variable gap is formed between the intermediate support sheet metal bracket 2 and the trough structure 5. When the intermediate transmission shaft assembly 1 of the vehicle is subjected to external force, the intermediate support sheet metal bracket 2 can rotate coaxially in the trough structure 5 to filter the vibration generated by the transmission shaft bearing 3, thereby preventing the intermediate support sheet metal bracket 2 from contacting and colliding with the trough structure 5. The multiple through holes on the trough structure 5 can filter the sand and dust carried by the mud and sand involved in the operation of the vehicle, and filter them directly to the ground, thereby avoiding deformation of the device due to blockage and accumulation of mud and sand, reducing damage to the bearing structure and the risk of abnormal noise, improving user comfort, and extending the service life of the intermediate transmission shaft assembly structure.
[0035] like Figures 3 to 5 As shown, the lightweight aluminum bracket 4 includes a vehicle connection surface 41, an assembly groove 42, a weight reduction groove 43, a bearing connection surface 44 and a bearing mounting hole 45. The two vehicle connection surfaces 41 are arranged at both ends of the lightweight aluminum bracket 4, and the assembly groove 42 is arranged at the edges of the two vehicle connection surfaces 41 to ensure that there is a large spacing between the assembly grooves 42, thereby increasing the contact area between the vehicle and the vehicle connection surface 41, and reducing the position change of the vehicle and the lightweight aluminum bracket 4 caused by vibration when the vehicle is working; the weight reduction groove 43 is arranged between the two assembly grooves 42, and the weight reduction groove 43 is a through hole structure, which further reduces the weight of the lightweight aluminum bracket 4; the bearing mounting holes 45 are symmetrically arranged on the bearing connection surfaces 44 on both sides.
[0036] Preferably, the height of the bearing connection surface 44 is higher than the height of the vehicle connection surface 41, so as to facilitate installation of the intermediate support sheet metal bracket 2 on the lightweight aluminum bracket 4 and ensure normal operation of the intermediate transmission shaft assembly 1 in the vehicle.
[0037] Bolt holes 8 are provided on the lug baffles on both sides of the intermediate support sheet metal bracket 2, which correspond to the size and position of the bearing mounting hole 45. The intermediate support sheet metal bracket 2 is connected to the lightweight aluminum bracket 4 by bolts 6. Since the water tank structure 5 is provided in the lightweight aluminum bracket 4, when the lightweight aluminum bracket 4 is subjected to external force, the water tank structure 5 is prone to twisting or bending. In order to improve the strength of the water tank structure 5, reinforcing ribs 7 are provided on both sides of the water tank structure 5. The reinforcing ribs 7 are provided along the side curved surface of the groove of the water tank structure 5, and the height of the reinforcing ribs 7 on both sides is slightly higher than the edge of the water tank structure 5, which can greatly enhance the support strength of the lightweight aluminum bracket 4. The reinforcing ribs 7 can significantly enhance the strength and rigidity of the lightweight aluminum bracket 4 without increasing the wall thickness, and prevent distortion and deformation. This helps to save material usage, reduce weight, and reduce production costs.
[0038] Finally, it should be noted that the above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model.

The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.
