Technical Field

[0001] The utility model relates to the technical field of limiting devices, in particular to a suspension limiting device, and also relates to a vehicle. Background Art

[0002] The suspension limiting block is an important buffer component in the vehicle suspension, mainly used to ensure the safety, comfort, handling and stability of the suspension system. At the same time, by restricting the longitudinal displacement of the axle, the suspension limiting block can prevent the leaf spring from exceeding the yield limit due to excessive dynamic deflection, thereby ensuring the stability and safety of vehicle driving. In order to ensure strength, the traditional limiting block bracket usually has a relatively large size design, occupies a large space, and cannot make full use of the limited space of the suspension system. This may lead to limited installation space for other important components and affect the optimization of the overall layout. Summary of the Utility Model

[0003] The utility model provides a suspension limiting device to solve the defect that the existing suspension limiting device has a relatively large size design and occupies a large space, and realizes that the limiting device occupies a smaller space and avoids the limited installation space of other components.

[0008] By adopting the above embodiments, the connection between the bracket, the limiting block and the connecting rod can be made more stable through the setting of the gasket, preventing loosening and displacement, and improving the overall reliability.

[0009] In some embodiments of the utility model, a plurality of hollow holes are formed on the bracket.
