Problems solved by technology
[0002] At present, the front beam supporting the automobile gearbox is a stamped plate, which is directly connected to the inner side of the frame longitudinal beam. The connection strength is not high, and the stiffness of the front beam itself is not high. Resonance phenomenon, resulting in loose connection, has an adverse effect on the load and safety of the vehicle

The invention provides a reinforced front beam assembly. The reinforced front beam assembly comprises a front beam, an upper reinforcing plate, two sealing gaskets and a vibration absorption plate, wherein the vibration absorbing plate is sandwiched between the two sealing gaskets so that a composite vibration attenuation device can be formed. The composite vibration attenuation device is arranged between the front beam and the upper reinforcing plate, and the composite vibration attenuation device, the front beam and the upper reinforcing plate are connected into a whole through bolts. The vibration absorption plate is made of a steel plate with the thickness being 2-4 mm. According to the reinforced front beam assembly, the upper reinforcing plate is additionally arranged, and therefore strength and rigidity are improved. Due to the arrangement of the composite vibration attenuation device, vibration transmission is reduced, particularly, part of vibration is absorbed through the vibration absorbing plate, then vibration is buffered through the sealing gaskets, and therefore the resonance phenomenon is totally avoided.
Description
technical field [0001] The invention belongs to the field of commercial vehicle frames, in particular to a reinforced front crossbeam assembly supporting an automobile gearbox. Background technique [0002] At present, the front beam supporting the automobile gearbox is a stamped plate, which is directly connected to the inner side of the frame longitudinal beam. The connection strength is not high, and the stiffness of the front beam itself is not high. Resonance phenomenon, resulting in loose connection, has an adverse effect on the load and safety of the vehicle. Contents of the invention [0003] In order to improve the strength and rigidity, reduce the transmission of vibration, and avoid the occurrence of resonance phenomenon, the present invention proposes a reinforced front beam assembly. [0004] For this reason, the technical solution of the present invention is: a reinforced front beam assembly, including the front beam, characterized in that it is also provide...
