Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 4, the front bracket of the engine comprises a damper cylinder 1, and an upper bracket 2 and a lower bracket 3 welded on the outer wall of the damper cylinder 1, wherein the damper cylinder 1 is an annular cylindrical body, the upper bracket 2 and the lower bracket 3 are respectively welded on the upper end and the lower end of the outer peripheral surface of the damper cylinder 1, and arc-shaped notches attached to the outer peripheral surface of the damper cylinder 1 are respectively formed on one sides of the upper bracket 2 and the lower bracket 3 close to the damper cylinder 1 so as to be attached to the damper cylinder 1 seamlessly, so that the upper bracket and the lower bracket are stressed more uniformly; the upper bracket 2 is a bent U-shaped steel plate, the top of the upper bracket is a horizontal first mounting plate 21, a first through hole 211 is formed in the middle of the first mounting plate 21, a welding nut 4 is fixed on one side, close to the vibration damping cylinder, of the first through hole 211, the left end face and the right end face, penetrating through the upper bracket 2, of the upper bracket are vertical faces, and the horizontal width of the upper bracket 2 is smaller than that of the lower bracket 3; the lower bracket 3 is also a bent U-shaped steel plate, the bottom is a horizontal second mounting plate 31, the front and rear steel plates are respectively a front plate 32 and a rear plate 33, the left and right end surfaces of the lower bracket 3 have different included angles with the second mounting plate 31, the left end surface has a smaller included angle with the second mounting plate 31, use 1 vertical direction both ends point line of damper cylinder as the central line promptly, second mounting panel 31 left end face is longer apart from the central line distance, asymmetric design is more convenient for the installation, match the engine shape more, second mounting panel 31 is provided with two second through-holes 311 about the central line asymmetry, the second through-hole 311 of left end face one side is farther apart from the central line distance, one side that second through-hole 311 is close to the damper cylinder is fixed with weld nut 4, be triangular distribution on 4 spaces of three weld nut, make the installation more firm, thereby vibration/noise reduction's effect has further been improved.
