Description

Technical Field

[0001] The utility model relates to the technical field of dump truck frame connecting pieces, in particular to an integrated connecting bracket for a dump truck. Background Art

[0002] As an important component of the upper part of a dump truck, the subframe is usually welded with a connecting bracket on the side of the subframe and fastened with bolts to the bracket reserved on the side of the main frame. The subframe longitudinal beam can be pressed tightly against the main frame longitudinal beam. At the same time, the friction between the two contact surfaces can prevent the subframe from moving forward and backward and swinging left and right on the frame, which can effectively improve the stability and reliability of the entire vehicle.

[0003] In addition to reducing the risk of pedestrians being rolled under the vehicle, side guards also provide a certain degree of protection for components such as the fuel tank, and can also reduce casualties caused by collisions with small vehicles. The new version of the national mandatory standard "Requirements for Side and Rear Lower Parts of Motor Vehicles and Trailers" (GB 11567-2017) has been implemented since January 1, 2018, mainly protecting unprotected road users - pedestrians, cyclists or motorcyclists who may fall into the side of the vehicle and be rolled under the wheels when using the road.

[0004] The side guard is used to prevent unprotected road users from falling into the side of the vehicle and being rolled under the wheels. It is an important safety barrier between pedestrians and vehicles. Based on this, the side guard must be strong enough to resist damage caused by external forces.

[0005] Under the current circumstances, the connecting bracket of the sub-frame and the main frame is designed separately, and the bracket for fixing the side protection device is also designed separately, and the two brackets are independent of each other. Based on this background, this scheme designs an integrated bracket that integrates the two brackets to reduce the number of parts, improve the integration of the connecting devices on the frame, and reduce the space occupied by the components.
