Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle accessories, and in particular relates to a left front suspension upper bracket for a heavy truck. Background Art

[0002] As people's living standards gradually improve, the popularity and demand for cars are increasing day by day, and cars play an important role in people's lives. With the development of the logistics and transportation industry, trucks play an increasingly important role in freight transportation due to their flexible transportation methods and fast transportation speeds. With the advancement of technology and the continuous increase in customer demand, users have put forward higher requirements for the comfort, convenience, lightness and safety of truck cabs. The safety of the cab is mainly based on the protection of the driver. The front assembly, as an important part of the cab, ensures the torsional stiffness of the body and good collision performance.

[0003] Chinese invention patent CN103029758A discloses a front enclosure assembly of a light truck cab, which includes a front enclosure outer panel and a left panel upper bracket and a right panel upper bracket fixed thereon, and a front enclosure reinforcement plate assembly serving as a skeleton is also provided inside, and a gap is provided between the front enclosure outer panel and the front enclosure reinforcement plate. Through the crossbeam and frame-type structural design of the front enclosure inner panel assembly, an effective cavity structure is formed after welding, and is coated with expansion glue, which can absorb energy in the event of a frontal impact, reduce the collapse and deformation of the front enclosure, and thus protect the occupants.

[0004] Invention patent CN103029758A solves the problem of weak rigidity and strength of the cab front panel assembly. However, increasing the rigidity and strength of the front panel assembly will greatly increase the manufacturing cost and the weight of the vehicle body. In addition, in the existing cab, the front suspension upper bracket is often arranged behind the front panel upper cross beam. During the simulation test, the front pendulum will first hit the front panel upper cross beam during the collision, and the upper part of the front panel will be greatly deformed before contacting the front suspension upper bracket. Since the large deformation of the front panel will cause the deformation of the instrument panel, this structure cannot ensure that the occupants have enough living space.

[0005] The current left front suspension upper bracket is large in size and weight, occupies a lot of installation space, and multiple functional component brackets adopt a welded assembly structure with poor structural rigidity, and safety performance cannot be well guaranteed.
