Description

Technical Field

[0001] The utility model relates to a cab tilting system, in particular to a cab tilting system integrating a hydraulic cylinder support and an anti-falling device. Background Art

[0002] At present, the anti-fallback device of the cab tilting system of special heavy trucks adopts a separately designed structure. The device consists of (such as Figure 1 (As shown in the figure) The cab front suspension consists of 1, 2 hydraulic cylinder upper supports, 3 anti-fall lever, 4 hydraulic cylinder, 5 anti-fall lower support, 6 hydraulic cylinder lower support, and 7 anti-fall upper support. The system first designs the anti-fall lower support 5, which is bolted to the frame longitudinal rail. Next, the anti-fall upper support 7 is bolted to the cab longitudinal rail. After the cab tipping operation is completed, the anti-fall lever 3 is placed in the support to prevent the cab from falling back.

[0003] The existing solution has many problems, such as the anti-fallback device is designed separately, which occupies a large space in the vehicle, has high design costs, and cannot be effectively integrated. Utility Model Content

[0004] The purpose of this utility model is to provide a cab tilting system for heavy-duty special vehicles that integrates a hydraulic cylinder support and an anti-fallback device. This system addresses the numerous issues with existing anti-fallback devices, such as their separate design, large space requirements, and inability to be effectively integrated. This system improves operator safety during cab tilting operations and, through its integrated nature, saves space on the vehicle, facilitating the removal and installation of other systems.

[0005] The utility model is realized by the following technical solutions:

[0006] A cab tilting system integrating a hydraulic cylinder support and an anti-fall device includes a cab front suspension 1, a cab longitudinal beam 2, a hydraulic cylinder upper support 3, a connecting pin 4, an anti-fall lever 5, a hydraulic cylinder 6, an anti-fall lower support 7, a hydraulic cylinder lower support 8, a frame 9 and an anti-fall upper support 10. The lower support of the cab front suspension 1 and the hydraulic cylinder lower support 8 are connected to the frame 9 by bolts, the upper support of the cab front suspension 1 and the hydraulic cylinder upper support 3 are connected to the cab longitudinal beam 2 by bolts, the anti-fall lower support 7 is connected to the hydraulic cylinder lower support 8 by bolts, and the anti-fall upper support 10 is connected to the hydraulic cylinder upper support 3 by the connecting pin 4.

[0007] The utility model can improve the safety of workers in preventing the cab from falling back during tilting operations, and at the same time, the integrated device feature can save space in the entire vehicle, save costs, and facilitate the disassembly and installation of other systems. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1It is the existing structure of the existing cab tilting system;

[0009] Figure 2 It is a schematic diagram of the present utility model. DETAILED DESCRIPTION

[0010] The utility model is a cab tilting system for heavy trucks that integrates a hydraulic cylinder support and an anti-falling device. The device comprises ( Figure 2 As shown): Cab front suspension 1, cab longitudinal beam 2, hydraulic cylinder upper support 3, connecting pin 4, anti-fall lever 5, hydraulic cylinder 6, anti-fall lower support 7, hydraulic cylinder lower support 8, frame 9, anti-fall upper support 10.

[0011] First, bolt the cab front suspension 1 lower support and hydraulic cylinder lower support 8 to the vehicle frame 9. Bolt the cab front suspension 1 upper support and hydraulic cylinder upper support 3 to the cab longitudinal beam 2. Finally, bolt the anti-rollback lower support 7 to the hydraulic cylinder lower support 8, and bolt the anti-rollback upper support 10 to the hydraulic cylinder upper support 3. Once installed, the cab tilting system tilts around the cab front suspension 1's rotation axis under the thrust of hydraulic cylinder 6. After reaching the maximum tilt angle (25 degrees), the three hydraulic cylinders cease operation. Since the anti-rollback lower support 7 and hydraulic cylinder lower support 8 are bolted together to the vehicle frame 9 longitudinal beam, and the hydraulic cylinder upper support 3 and anti-rollback upper support 10 are bolted together using connecting pins 4, the anti-rollback lever 5 is secured to the anti-rollback upper and lower supports.
