[0020] Please refer to Figures 1 to 5As shown, the present invention discloses an exhaust gas after-treatment package 100, which includes a first after-treatment component 1, a second after-treatment component 2 parallel to the first after-treatment component 1, a connecting cavity 3 connecting the first after-treatment component 1 and the second after-treatment component 2, and a bracket component 4 fixing the first after-treatment component 1 and the second after-treatment component 2 together.
[0021] In the illustrated embodiment of the present invention, the exhaust gas after-treatment package 100 is U-shaped. The first after-treatment component 1 is provided with a first after-treatment cylinder 11 and a first carrier located in the first after-treatment cylinder 11. The second after-treatment component 2 is provided with a second after-treatment cylinder 21 and a second carrier located in the second after-treatment cylinder 21.
[0022] The bracket assembly 4 includes a first strap 41 for binding the first post-processing cylinder 11, a second strap 42 for binding the second post-processing cylinder 21, a first bracket 43 located below the first strap 41 and used to support the first post-processing cylinder 11, and a second bracket 44 located below the second strap 42 and used to support the second post-processing cylinder 21. The first strap 41 is provided with a first joint bolt 411 for adjusting the tightness; the second strap 42 is provided with a second joint bolt 421 for adjusting the tightness. The first bracket 43 is provided with a first arc-shaped support surface 431 extending into the inner circle of the first strap 41, and the first arc-shaped support surface 431 is used to support the first post-processing cylinder 11. The second bracket 44 is provided with a second arc-shaped support surface 441 extending into the inner circle of the second strap 42, and the second arc-shaped support surface 441 is used to support the second post-processing cylinder 21.
[0023] In the illustrated embodiment of the present invention, the first binding strap 41 and the second binding strap 42 are only used to bind the corresponding first post-processing cylinder 11 and the second post-processing cylinder 21, but do not bear the weight of the first post-processing cylinder 11 and the second post-processing cylinder 21. Accordingly, the weight of the first post-processing cylinder 11 and the second post-processing cylinder 21 is borne by the first bracket 43 and the second bracket 44. Such a configuration, on the one hand, reduces the design requirements of the binding strap and saves costs; on the other hand, through the support of the bracket, it can prevent the risk of the cylinder falling when the binding strap fails, thereby improving the safety factor of the product.
[0024] Specifically, the bracket assembly 4 includes a first side bracket 45 and a second side bracket 46 connecting the first bracket 43 and the second bracket 44. The first side bracket 45 is detachably connected to one side of the first bracket 43 and the second bracket 44, and the second side bracket 46 is detachably connected to the other side of the first bracket 43 and the second bracket 44. The first side bracket 45 and the second side bracket 46 are detachably connected to the first bracket 43 and the second bracket 44 by bolts. The first side bracket 45 is provided with a first hoisting hole 451, and the second side bracket 46 is provided with a second hoisting hole 461, so as to facilitate the installation of the exhaust gas post-treatment package 100 on the vehicle through a lifting device. The first side bracket 45 and / or the second side bracket 46 are provided with a mounting hole 47 for mounting the bracket assembly 4 on the vehicle frame.
