Abstract

The utility model discloses a light-weight round girder assembly. The problems of complex structure, heavy weight and easy interference with other systems in the process of mounting the conventional round girder are solved. The light-weight round girder assembly comprises a round girder body which consists of a U-shaped plate and end plates which are fixed into an integral structure at two ends of the U-shaped plate, wherein an oil leakage hole is formed in the middle of a lower end face of the round girder body; L-shaped connecting plates are connected to the two end plates of the round girder body; bolt holes connected with side wing surfaces of the frame are formed in the connecting plates; and bolts connected with the lower wing surface of the frame are connected to the two end plates of the round girder body on the inner sides of the connecting plates. The light-weight round girder assembly is reasonable and reliable in structural design, firm and reliable in connection, light in weight, and easy, convenient and feasible to mount and has the advantages of impact resistance, fatigue resistance, light weight and convenience in assembly, the structure is simplified, the production cycle is shortened, the cost is reduced, extremely large space is not required to be occupied during whole vehicle arrangement, the requirements of assembly personnel are reduced, and the requirement of light-weight design is met.

Description

Lightweight ingot beam assembly

Technical field

The utility model relates to the heavy duty truck engine fender guard, is specially a kind of lightweight ingot beam assembly.

Background technology

The lightweight of heavy duty truck is exactly under the prerequisite that guarantees its intensity and safety performance, reduces the curb mass of truck as much as possible, thereby improves the dynamic property of truck, reduces consumption of fuel, reduces exhaust pollution.

The engine protection device of the straight-through beam vehicle of existing heavy duty truck is protected through the ingot beam; The ingot beam is installed on the flat spring bracket; Make the flat spring bracket complex structure, weight is big, and the ingot beam is not long-term heavy duty; Need not therefore strengthen the design complexities of flat spring bracket specially, and oversize support and the other system of causing of contoured cradle interfered.

Summary of the invention

Complex structure when the utility model is installed in order to solve existing ingot beam, weight is big and be easy to the problem that other system is interfered, and a kind of lightweight ingot beam assembly is provided.

The utility model is to adopt following technical scheme to realize: lightweight ingot beam assembly; Comprise by the U template and with the U template two ends ingot beam body that the end plate of structure forms that is fixed as one; The middle part, lower surface of ingot beam body has oil leaking hole; Be connected with L type connecting panel on the two end plates of ingot beam body, have on the connecting panel and frame sides aerofoil bonded assembly bolt hole, and be connected with and vehicle frame lower aerofoil bonded assembly bolt on the ingot beam body two end plates of connecting panel inboard.

Ingot beam assembly is captiveed joint with vehicle frame through bolt, nut; Simple in structure, the selection standard is lower, secure with ingot beam body-fixed on vehicle frame; Make simultaneously that flat spring bracket simplifies the structure, lightweight, and reduced the many interference problems with other system.

The utility model reasonable in design is reliable, designs simplification, and the production cycle shortens; Reduce cost, and need not when car load is arranged, to take excessive space, firm and reliable connection; Simple installation is prone to row, and is in light weight, reduced the requirement to the assembly crewman; Realize the requirement of light-weight design, had shock resistance, endurance, advantage in light weight and easy to assembly.
