Abstract
The invention provides an improved truck engine rear supporting device. An engine rear supporting support assembly is formed by installing and welding a left supporting plate, a left connecting plate, a supporting crossbeam, a right connecting plate and a right supporting plate. The engine rear supporting support assembly is firmly connected with a truck frame left longitudinal beam and a truck frame right longitudinal beam through bolts and self-locking nuts. An engine is installed on the supporting crossbeam of the engine rear supporting support assembly through buffering rubber pads, bowl-shaped pads, connecting bolts, nuts and the like. By the adoption of the improved truck engine rear supporting device, the structural form of the engine rear supporting device is thoroughly changed, and an original two-cantilever-beam supporting structure is changed into a simply supported beam supporting structure. The strength and rigidity of the engine rear supporting device are greatly improved, the phenomena that the position of the inner side of an engine rear supporting support falls and is broken cannot happen any more, the use reliability of a truck is greatly improved, and the service life of related components of the engine rear supporting device is greatly prolonged.
