Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a chassis and a vehicle. Background Technology

[0002] In existing technologies, heavy-duty trucks are often equipped with V-shaped push suspensions to ensure vehicle safety and prevent excessive lateral roll during cornering, thus maintaining overall vehicle lateral stability. When the braking system is arranged, the service valve and parking valve are located on the front and rear sides of the crossbeam, respectively. Consequently, the air chamber lines of the middle and rear axles, exiting from the service valve and parking valve outlets, often pass under the V-shaped push suspension, making them prone to wear.

[0003] When the V-shaped push suspension is replaced with a straight push suspension, the air chamber lines of the middle axle and the rear axle cannot be fixed on the underside of the crossbeam, so the air chamber lines cannot pass through here. Utility Model Content

[0035] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0036] The following is for reference. Figures 1-4 The chassis 100 according to an embodiment of the present utility model is described.

[0037] Reference Figure 1 As shown, the chassis 100 of the first aspect of this utility model includes: a frame 10, a thrust rod 20, an air chamber 30, a brake valve assembly 40, and an air chamber pipeline 50. The frame 10 includes longitudinal beams 11 and crossbeams 12. The crossbeams 12 are transversely arranged between the longitudinal beams 11. The thrust rod 20 is longitudinally connected to the middle of the crossbeams 12 and is perpendicular to the length direction of the crossbeams 12. The brake valve assembly 40 is connected to the longitudinal beams 11. One end of the air chamber pipeline 50 is connected to the air chamber 30, and the other end of the air chamber pipeline 50 is connected to the brake valve assembly 40. One section of the air chamber pipeline 50 is located on the crossbeam 12, and the other section is located on the thrust rod 20, extending along the length direction of the thrust rod 20.

[0038] Specifically, the chassis 100 mainly consists of a frame 10, a thrust rod 20, an air chamber 30, a brake valve assembly 40, and an air chamber pipeline 50. The thrust rod 20 is the suspension of the chassis 100, which is used to prevent the vehicle body from tilting too much when turning, thereby maintaining the stability of the whole vehicle.

[0039] The thrust rod 20 is longitudinally connected to the middle of the crossbeam 12. The longitudinal direction is the front-to-back direction of the vehicle, which is the length direction of the vehicle. The thrust rod 20 is straight and parallel to the longitudinal beam 11. The thrust rod 20 is connected to the middle of the crossbeam 12, which can provide more concentrated support force, thereby improving the rigidity and strength of the chassis 100 structure. It can also provide an installation position and support for the air chamber pipeline 50. This facilitates the layout of the air chamber pipeline 50 and prevents wear on the air chamber pipeline 50.

[0040] Moreover, the thrust rod 20 is perpendicular to the length direction of the crossbeam 12, which not only improves the load-bearing capacity in the length direction perpendicular to the crossbeam 12, but also facilitates the arrangement of the air chamber pipeline 50 along the thrust rod 20.

[0041] The main function of the air chamber 30 is to convert the pressure of compressed air into mechanical force, thereby enabling the vehicle's braking function. One end of the air chamber pipe 50 is connected to the air chamber 30, and the other end of the air chamber pipe 50 is connected to the brake valve assembly 40. When the driver presses the brake pedal, the brake valve assembly 40 will work quickly, and compressed air can be directly transmitted to the air chamber 30 through the air chamber pipe 50, thereby braking the vehicle.

[0042] Furthermore, the frame 10 is mainly composed of longitudinal beams 11 and crossbeams 12. The crossbeams 12 are arranged laterally between the longitudinal beams 11. The crossbeams 12 can serve as the balance axis of the frame 10, thereby providing lateral support to the frame 10.

[0043] Furthermore, the brake valve assembly 40 is connected to the longitudinal beam 11. Since the thrust rod 20 is longitudinally connected to the middle of the cross beam 12, the space in the middle of the cross beam 12 is occupied by the thrust rod 20. Therefore, by fixing the brake valve assembly 40 to the longitudinal beam 11, the longitudinal beam 11 can provide installation space for the brake valve assembly 40.

[0044] Furthermore, one end of the air chamber pipe 50 is set on the crossbeam 12, and the other end of the air chamber pipe 50 is set on the thrust rod 20. The other end of the air chamber pipe 50 can be set on the side and top surface of the thrust rod 20 (the air chamber pipe 50 is not set below the thrust rod 20). In this way, one end of the air chamber pipe 50 can be fixedly connected to the crossbeam 12, and the other end of the air chamber pipe 50 can be fixedly connected to the thrust rod 20. Thus, the crossbeam 12 and the thrust rod 20 can provide an installation position for the air chamber pipe 50.

[0045] Furthermore, the other section of the air chamber pipe 50 extends along the length of the thrust rod 20, which can provide a certain installation path, thereby enabling the positioning and installation of the air chamber pipe 50, ensuring a neat and smooth arrangement of the air chamber pipe 50, and preventing interference between the air chamber pipe 50 and the surrounding frame 10 and bolts, thus ensuring the braking function.

[0046] Therefore, the crossbeam 12 and thrust rod 20 in the chassis 100 can provide an installation position for the air chamber pipeline 50 and a certain installation path, thereby enabling the positioning and installation of the air chamber pipeline 50, ensuring a neat and smooth arrangement of the air chamber pipeline 50, and preventing interference between the air chamber pipeline 50 and the surrounding frame 10 and bolts, thus ensuring the braking function.

[0047] According to some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, another section of the air chamber pipe 50 is located on the upper surface of the thrust rod 20.

[0048] The upper surface of the thrust rod 20, i.e. the top surface of the thrust rod 20, can provide an installation position for the other section of the air chamber pipe 50, and can also provide support for the air chamber pipe 50. In this way, the other section of the air chamber pipe 50 can make reasonable use of the space of the thrust rod 20, so that it extends neatly along the length of the thrust rod 20.

[0049] According to some embodiments of this utility model, such as Figure 2 As shown, the chassis 100 also includes a first pipeline fixing member 60, which is disposed on another section of the air chamber pipeline 50 and is connected to the thrust rod 20.

[0050] The first pipeline fixing component 60 can be set as a cable tie. The first pipeline fixing component 60 can be set around the other section of the air chamber pipeline 50 and the outer periphery of the thrust rod 20. In this way, the other section of the air chamber pipeline 50 can be prevented from detaching from the thrust rod 20, and the connection between the other section of the air chamber pipeline 50 and the thrust rod 20 can be more stable and firm.

[0051] Furthermore, an elastic element is provided between another section of the air chamber pipe 50 and the thrust rod 20. For example, the elastic element can be a rubber block. By providing a rubber block between the air chamber pipe 50 and the thrust rod 20, vibration can be effectively absorbed and mitigated. Since vibration can cause friction between the air chamber pipe 50 and other metal parts, leading to wear or even breakage, the rubber block can provide an additional buffer layer, thereby preventing damage to the air chamber pipe 50.

[0052] According to some embodiments of the present invention, there are multiple first pipeline fixing members 60, and the multiple first pipeline fixing members 60 are distributed at intervals along the length direction of the thrust rod 20.

[0053] One section of the air chamber pipe 50 extends along the length of the thrust rod 20. Therefore, multiple first pipe fixing parts 60 are distributed at intervals along the length of the thrust rod 20, which can fix different positions of the other section of the air chamber pipe 50 on the thrust rod 20, thereby preventing the air chamber pipe 50 from moving and also preventing the air chamber pipe 50 from wearing.

[0054] According to some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the chassis 100 also includes a bracket 70 and a second pipeline fixing member 80. The bracket 70 is disposed on one side of the crossbeam 12, and the second pipeline fixing member 80 is disposed on a section of the air chamber pipeline 50, and the second pipeline fixing member 80 is connected to the bracket 70.

[0055] The bracket 70 is located on the side of the crossbeam 12 near the longitudinal beam 11, so that a section of the air chamber pipe 50 can be fixed on the bracket 70 of the crossbeam 12, thereby providing an installation position and support for a section of the air chamber pipe 50.

[0056] Furthermore, the second pipe fixing component 80 is installed on a section of the air chamber pipe 50. The second pipe fixing component 80 can be a cable tie. The second pipe fixing component 80 can fix and constrain a section of the air chamber pipe 50, thereby avoiding a messy distribution of a section of the air chamber pipe 50.

[0057] Meanwhile, the second pipeline fixing component 80 is also connected to the bracket 70, so that a section of the air chamber pipeline 50 can be fixed on the bracket 70, thereby preventing the section of the air chamber pipeline 50 from moving and from being worn.

[0058] According to specific embodiments of this utility model, such as Figure 3 As shown, the chassis 100 also includes: a central axle 81, which is disposed on the longitudinal beam 11 and located in front of the cross beam 12; a thrust rod 20 including a central thrust rod 21 located in front of the cross beam 12 and connected to the central axle 81; an air chamber 30 including a central air chamber 31 corresponding to the central axle 81; and an air chamber pipeline 50 including a central air chamber pipeline 51 connected between the central air chamber 31 and the brake valve assembly 40, with one section of the central air chamber pipeline 51 disposed on the cross beam 12 and the other section of the central air chamber pipeline 51 disposed on the central thrust rod 21.

[0059] Specifically, the CRRC axle 81 is connected to the longitudinal beam 11 via suspension leaf springs. The CRRC axle 81 is located on the front side of the crossbeam 12, which can distribute the total weight of the front side of the crossbeam 12 more evenly and avoid the problem of rear overload or front insufficient load, thereby ensuring the balance of the front side of the crossbeam 12.

[0060] Furthermore, the thrust rod 20 includes a central thrust rod 21 located in front of the crossbeam 12. One end of the central thrust rod 21 is connected to the CRRC axle 81, and the other end of the central thrust rod 21 is connected to the middle of the crossbeam 12. In this way, the central thrust rod 21 can provide support force between the CRRC axle 81 and the crossbeam 12, thereby improving the strength and rigidity between the CRRC axle 81 and the crossbeam 12.

[0061] Furthermore, the intermediate gas chamber 31 is located on the CRRC axle 81, which provides the installation position and space for the intermediate gas chamber 31. One end of the intermediate gas chamber pipeline 51 is fixed to the crossbeam 12, and the other end is fixed to the thrust rod 21. In this way, the intermediate gas chamber pipeline 51 can extend along the length of the crossbeam 12 and the thrust rod 21 respectively, thus providing a better installation path for the intermediate gas chamber pipeline 51 and making the intermediate gas chamber pipeline 51 neater and smoother.

[0062] According to some embodiments of the present invention, the chassis 100 further includes: a rear axle 82, which is disposed on the longitudinal beam 11 and located on the rear side of the cross beam 12; a thrust rod 20 including a rear thrust rod 22 located behind the cross beam 12 and connected to the rear axle 82; an air chamber 30 including a rear air chamber 32 corresponding to the rear axle 82; and an air chamber pipeline 50 including a rear air chamber pipeline 52 connected between the rear air chamber 32 and the brake valve assembly 40, with one end of the rear air chamber pipeline 52 disposed on the cross beam 12 and the other end of the rear air chamber pipeline 52 disposed on the rear thrust rod 22.

[0063] The rear axle 82 is connected to the longitudinal beam 11 via suspension leaf springs. The rear axle 82 is located behind the crossbeam 12, which can distribute the total weight of the rear side of the crossbeam 12 more evenly, thereby ensuring the balance of the rear side of the crossbeam 12.

[0064] Furthermore, the thrust rod 20 includes a rear thrust rod 22 located behind the crossbeam 12. One end of the rear thrust rod 22 is connected to the rear axle 82, and the other end of the rear thrust rod 22 is connected to the middle of the crossbeam 12. In this way, the rear thrust rod 22 can provide support force between the rear axle 82 and the crossbeam 12, thereby improving the strength and rigidity between the rear axle 82 and the crossbeam 12.

[0065] Furthermore, the rear air chamber 32 is located on the rear axle 82. One end of the rear air chamber 32 pipe is fixed to the crossbeam 12, and the other end of the rear air chamber pipe 52 is fixed to the rear thrust rod 22. In this way, the rear air chamber pipe 52 can extend along the length of the crossbeam 12 and the rear thrust rod 22 respectively, thereby providing a better installation path for the rear air chamber pipe 52, making the rear air chamber pipe 52 neater and smoother, and avoiding interference between the rear air chamber pipe 52 and the middle air chamber pipe 51.

[0066] According to a specific embodiment of this utility model, the brake valve assembly 40 includes a parking valve 41 and a driving valve 42. Both the parking valve 41 and the driving valve 42 are disposed on the longitudinal beam 11. The parking valve 41 is located on the front side of the crossbeam 12, and the driving valve 42 is located on the rear side of the crossbeam 12. The middle air chamber pipeline 51 includes a middle parking air chamber pipeline 511 and a middle driving air chamber pipeline 512. The middle parking air chamber pipeline 511 is connected to the middle air chamber 31 and the parking valve 41, respectively. The middle driving air chamber pipeline 512 is connected to the middle air chamber 31 and the driving valve 42, respectively. The rear air chamber pipeline 52 includes a rear parking air chamber pipeline 521 and a rear driving air chamber pipeline 522. The rear parking air chamber pipeline 521 is connected to the rear air chamber 32 and the parking valve 41, respectively. The rear driving air chamber pipeline 522 is connected to the rear air chamber 32 and the driving valve 42, respectively.

[0067] Specifically, the parking valve 41 is mainly used for static braking when the vehicle is parked, ensuring that the vehicle does not accidentally slip. The service valve 42 is mainly used for dynamic braking during vehicle movement, ensuring that the vehicle decelerates or stops. In this way, independent control of the service brake and parking brake can be achieved.

[0068] The parking valve 41 and the driving valve 42 are both located on the longitudinal beam 11. The longitudinal beam 11 can provide an installation position for the parking valve 41 and the driving valve 42, and can also prevent the parking valve 41 and the driving valve 42 from occupying the space of the cross beam 12.

[0069] Furthermore, the bracket 70 includes a first bracket 71 and a second bracket 72. The first bracket 71 is disposed at the front of the crossbeam 12. The first bracket 71 is used to fix one section of the parking air chamber pipe 511. The other section of the parking air chamber pipe 511 is fixedly connected to the middle thrust rod 21, thereby realizing the fixation of the parking air chamber pipe 511.

[0070] Meanwhile, the first bracket 71 can also fix one section of the central engine air chamber pipe 512, and the other section of the central engine air chamber pipe 512 is fixedly connected to the central thrust rod 21, thereby achieving the fixation of the central engine air chamber pipe 512.

[0071] Furthermore, the second bracket 72 is located at the rear of the crossbeam 12. The second bracket 72 is used to fix one section of the rear parking air chamber pipe 521. The other section of the rear parking air chamber pipe 521 is fixedly connected to the rear thrust rod 22, thereby achieving the fixation of the rear parking air chamber pipe 521.

[0072] Meanwhile, the second bracket 72 can also fix one section of the rear vehicle air chamber pipe 522, and the other section of the rear vehicle air chamber pipe 522 is fixedly connected to the rear thrust rod 22, thereby achieving the fixation of the rear vehicle air chamber pipe 522.

[0073] Furthermore, since the middle parking air chamber pipe 511 is connected to the middle air chamber 31 and the parking valve 41 respectively, the parking valve 41 can adjust the air volume of the middle air chamber 31. Since the rear parking air chamber pipe 521 is connected to the rear air chamber 32 and the parking valve 41 respectively, the parking valve 41 can adjust the air volume of the rear air chamber 32, thereby enabling static braking of the vehicle.

[0074] Since the middle air chamber pipe 512 is connected to the middle air chamber 31 and the driving valve 42 respectively, the driving valve 42 can adjust the air volume of the middle air chamber 31. Since the rear air chamber pipe 522 is connected to the rear air chamber 32 and the driving valve 42 respectively, the driving valve 42 can adjust the air volume of the rear air chamber 32, thereby enabling dynamic braking of the vehicle.

[0075] According to some embodiments of this utility model, such as Figure 3 and Figure 4As shown, a further section 5121 of the central driving air chamber pipe is provided on the longitudinal beam 11, and the further section 5121 of the central driving air chamber pipe is located on the rear side of the cross beam 12. A further section 5211 of the rear parking air chamber pipe is provided on the longitudinal beam 11, and the further section 5211 of the rear parking air chamber pipe is located on the front side of the cross beam 12.

[0076] Among them, another section 5121 of the central crane air chamber pipeline is fixedly connected to the longitudinal beam 11. The other section 5121 of the central crane air chamber pipeline is the section of the central crane air chamber pipeline 512 near the crane valve 42. This can further fix the central crane air chamber pipeline 512 on the rear side of the cross beam 12, thereby preventing wear of the other section 5121 of the central crane air chamber pipeline.

[0077] Another section 5211 of the rear parking air chamber pipe is fixedly connected to the longitudinal beam 11. This section 5211 is the part of the rear parking air chamber pipe 521 that is close to the parking valve 41. This can further fix the rear parking air chamber pipe 521 on the front side of the cross beam 12, thereby preventing wear on the other section 5211 of the rear parking air chamber pipe.
