Engine front supporting device for heavy-duty truck

Abstract

The invention discloses an engine front supporting device for a heavy-duty truck. The device is characterized in that: a seamless steel pipe is bent to form a main beam of an engine front support assembly, connecting plates made of steel plates are respectively welded at two ends of the main beam, and a left supporting plate and a right supporting plate made of steel plates are symmetrically welded close to the connecting plates at two ends of the main beam; rectangular reinforcing plates made of steel plates are respectively welded at the upper parts of the left supporting plate and the right supporting plate, so that the left supporting plate, the right supporting plate and the connecting plates of two ends are firmly connected into a whole; triangular reinforcing plates made of steel plates are respectively welded at the lower parts of the two ends of the main beam to enhance the connecting strength of the main beam; and the engine front support assembly is placed at the inner side of left and right longitudinal beams and arranged on a frame. The device has relatively high strength and rigidity, and can be widely applied to the heavy-duty truck.

Description

technical field [0001] The invention relates to a supporting device for an automobile engine, in particular to a front supporting device for a heavy-duty truck engine. Background technique [0002] The car engine supporting device not only bears the weight of the engine, but also bears the reaction force of the torque output from the engine to the car transmission system. The front support of the car engine bears a large part of the weight and reaction force of the engine. At present, the commonly used engine front support device for the truck engine is: the engine is respectively supported on the left and right symmetrical engine front support body assemblies with two buffer rubber pads, and the two engine front support bodies are in a cantilever beam structure. All heavy-duty trucks use high-horsepower diesel engines, which have large weight and high torque, and have higher requirements for the front support of the engine. And along with the improvement of the strengtheni...

AI Technical Summary

Problems solved by technology

As a result, the longitudinal beam of the frame at the installation position of the currently used engine front support device is deformed, the position of the engine front support body assembly falls, and the relevant parameters of the automobile transmission system change, resulting in increased noise and wear of the relevant components of the transmission system, and damage to the cushion rubber pad The phenomenon is more common

Sometimes there is even a phenomenon that the front support body assembly of the engine breaks
