Description

Technical Field

[0001] This utility model relates to the field of heavy-duty truck chassis technology, and more particularly to an integrated chassis for heavy-duty trucks. Background Technology

[0002] The chassis of a heavy-duty truck is the core skeletal component that supports the overall structure of the heavy-duty truck, bears the core load, and connects key systems. It is the basic load-bearing structure for heavy-duty trucks to achieve driving and cargo-carrying functions. It not only needs to bear the weight of the cargo and the weight of the truck itself, but also needs to transmit the driving force of the power system and the shock absorption force of the suspension system. At the same time, it provides the mounting and positioning foundation for key components such as the engine, transmission, fuel tank, and wheels.

[0003] However, in the existing technology, most heavy truck frames adopt a split splicing structure. The main body of the frame is connected to the extension frame and auxiliary support components by bolts or welding. During long-term operation carrying heavy goods and driving in complex road conditions, the connection points between the main body of the frame and various components are prone to stress fatigue due to stress concentration, which can lead to cracking of weld points or loosening of bolts, thereby reducing the overall structural stability of the frame. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of stress fatigue at the connection points and severe wear of components due to the lack of buffer adjustment mechanisms in the existing heavy truck chassis, and to propose an integrated chassis for heavy trucks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated frame for a heavy-duty truck, comprising a frame body, extension frames integrated on the outer walls of both sides of the frame body, and a connecting mechanism integrated on the outer wall of the frame body. The connecting mechanism includes a positioning frame, a connecting rod, and a positioning end. The positioning frame is sleeved on the outer wall of the frame body. One end of the connecting rod is rotatably mounted on the bottom of the positioning frame, and the positioning end is rotatably mounted on the other end of the connecting rod. A hollow cylinder is fixedly connected to the top of the positioning end. An inclined frame is fixedly mounted on the top of the positioning frame, and a positioning rod is fixedly mounted on one end of the inclined frame. A rotating head is rotatably mounted on the outer wall of the positioning rod, and a guide rod is fixedly connected to one side of the rotating head. The guide rod is inserted into the interior of the hollow cylinder.

[0006] Preferably, a tension spring is fixedly connected to one end of the hollow cylinder, and the tension spring is fixedly connected to the rotating head.

[0007] Preferably, a filler block is fitted inside the frame body, and the filler blocks are symmetrically distributed on both sides of the frame body.

[0008] Preferably, one side of the positioning frame is in contact with the filling block, and a reinforcing plate is fixedly connected between the two filling blocks.

[0009] Preferably, a support rod is fixedly installed on the upper surface of the reinforcing plate, and a secondary support frame is integrated on the upper surface of the main body of the vehicle frame, with the support rod and the secondary support frame being at the same height.

[0010] Preferably, the positioning frame surrounds a rectangular hole, the shape of which is adapted to the main body of the vehicle frame.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by adopting an integrated structural design for the frame body and the extension frame, the positioning frame is precisely matched with the frame body through rectangular holes, which effectively disperses the stress concentration at the connection parts, avoids the stress fatigue problem caused by welding or bolt connection in traditional split structures, significantly improves the overall structural stability of the frame, and can buffer the impact load on the frame, reduce component wear, and solve the drawback of traditional frames lacking a buffer adjustment mechanism.

[0012] 2. In this utility model, when the vehicle turns, the frame will be subjected to centrifugal force, resulting in greater force on one side of the frame. The connecting mechanism can automatically adjust the position and angle of each component according to the force change of the frame, so that the force on the frame is more even, maintaining the balance of the vehicle, effectively reducing the risk of accidents such as rollover during driving, and improving the safety of vehicle driving.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an integrated frame for a heavy-duty truck, including a frame body 1. Extension frames 3 are integrated on the outer walls of both sides of the frame body 1. A connecting mechanism 4 is integrated on the outer wall of the frame body 1. The connecting mechanism 4 includes a positioning frame 41, a connecting rod 42, and a positioning end 43. The positioning frame 41 is sleeved on the outer wall of the frame body 1. One end of the connecting rod 42 is rotatably mounted on the bottom of the positioning frame 41, and the positioning end 43 is rotatably mounted on the other end of the connecting rod 42. A hollow cylinder 44 is fixedly connected to the top of the positioning end 43. An inclined frame 46 is fixedly mounted on the top of the positioning frame 41. A positioning rod 49 is fixedly mounted on one end of the inclined frame 46. A rotating head 48 is rotatably mounted on the outer wall of the positioning rod 49. A guide rod 45 is fixedly connected to one side of the rotating head 48. The guide rod 45 is inserted into the interior of the hollow cylinder 44. A tension spring 47 is fixedly connected to one end of the hollow cylinder 44. The tension spring 47 is fixedly connected to the rotating head 48.

[0018] The specific settings and functions of this embodiment are described below. The positioning frame 41 is sleeved on the outer wall of the frame body 1, serving as the basic component of the connecting mechanism. It provides a stable installation platform for subsequent components, ensuring that the entire mechanism can be securely connected to the frame body. One end of the connecting rod 42 is rotatably mounted at the bottom of the positioning frame 41, allowing for a certain degree of freedom of movement. The positioning end 43 connected to its other end is also rotatable, enabling the positioning end 43 to flexibly adjust its position under the drive of the connecting rod 42 to adapt to different connection and working requirements. For example, when encountering uneven or bumpy road conditions during vehicle operation, it can promptly change its angle to ensure the effectiveness of the connection. The positioning end 43 is used to connect with other parts such as wheels. When the vehicle is traveling on complex road conditions, such as over potholes, the frame will vibrate and displace in different directions. At this time, the positioning end 43 will be moved by the force, which in turn will drive the hollow cylinder 44 to move. When the hollow cylinder 44 moves, it will stretch or compress the tension spring 47. The subsequent rebound can push the positioning end 43 back to the initial position. At the same time, the guide rod 45 slides inside the hollow cylinder 44, which plays a guiding and limiting role, preventing excessive displacement of the components. This ensures that the connecting mechanism can flexibly adjust its position and maintain a stable connection when dealing with different road conditions, reducing the risk of damage to the frame caused by uneven force or excessive vibration, thereby ensuring the safety and stability of the heavy truck during driving.

[0019] Example 2: Figure 1 and Figure 2 As shown, a filling block 411 is fitted inside the frame body 1. The filling blocks 411 are symmetrically distributed on both sides of the frame body 1. One side of the positioning frame 41 is in contact with the filling block 411. A reinforcing plate 412 is fixedly connected between the two filling blocks 411. A support rod 413 is fixedly installed on the upper surface of the reinforcing plate 412. A secondary support frame 2 is integrated on the upper surface of the frame body 1. The support rod 413 is at the same height as the secondary support frame 2. The positioning frame 41 surrounds to form a rectangular hole 410. The shape of the rectangular hole 410 is adapted to the frame body 1.

[0020] The overall effect of this embodiment is that the rectangular hole 410 ensures that the positioning frame 41 can be accurately fitted onto the outer wall of the frame body 1, while one side of the positioning frame 41 fits against the filling block 411. With the support of the filling block 411, the positioning frame 41 is stably installed on the frame body 1. During the load-bearing process of the frame, the support rod 413 and the auxiliary support frame 2 work together to share the pressure and load on the frame body 1. The filling block 411 not only provides fitting support for the positioning frame 41, but also fills the gaps on the inner side of the frame body 1, enhancing the structural stability of the frame body 1 itself. The support rod 413 and the auxiliary support frame 2 can evenly distribute the pressure on the frame, reduce the situation of excessive local stress on the frame body 1, reduce the risk of frame deformation, extend the overall service life of the frame, and also provide a more stable support foundation for the installation of other components on the frame.

[0021] The usage and working principle of this device are as follows: First, the filling block 411 is installed on the inner side of the frame body 1. The filling block 411 can fill the gaps on the inner side of the frame body 1, enhance the structural stability of the frame body 1, and cooperate with the sub-support frame 2 to evenly distribute the pressure on the frame and reduce the situation of excessive local stress on the frame body 1. Then, the positioning frame 41 is fitted onto the outer wall of the frame body 1, ensuring that one side of the positioning frame 41 is in contact with the filling block 411 pre-fitted on the inner side of the frame body 1. When the vehicle is driving on complex road conditions, the positioning end 43 will be moved by force, which will drive the hollow cylinder 44 to move. When the hollow cylinder 44 moves, it will stretch or compress the tension spring 47. The subsequent rebound can push the positioning end 43 back to the initial position. At the same time, the guide rod 45 slides inside the hollow cylinder 44.

[0022] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
