The specific embodiment
Below with reference to drawings and Examples, a kind of rubber suspension member technical scheme for automobile exhaust system that the embodiment that the utility model is related to provides is described in further detail.
Refer to shown in Fig. 1, the automobile exhaust system that an embodiment of the present utility model provides comprise manage 5 after exhaust front pipe 2, ternary catalyzing unit 3, silencer 4, exhaust, trail pipe 6 and suspension hook 7 and rubber suspension member 1.Wherein, exhaust front pipe 2 with after exhaust, manage 5 between by flange, be connected with bolt and nut, the portable requirement of installing to meet the integrated and part of system.
As shown in Figure 1, in automobile exhaust system of the present utility model, the pipeline of exhaust front pipe 2 is connected with the mode of flexible joint 21 with welding, front end flange 22 is connected with engine exhaust manifold (not shown), rear end flanges 23 with after exhaust, manage 5 and be connected, exhaust front pipe 2 is selected the reasonable material of resistance to elevated temperatures.In addition, manage 5 pipeline and be connected with the mode of silencer 4 with welding with ternary catalyzing unit 3 after exhaust, its front end flange is connected with the rear end flanges 23 of exhaust front pipe 2, thereby its end is welded to trail pipe 6, waste gas is imported to atmosphere.After exhaust, manage 5 and select the reasonable material of decay resistance.
In exhaust system of the present utility model, the structure of suspension hook 7 curved syphon shape and be welded on freeing pipe and/or silencer on the position set, suspension hook 7 in the mounting hole 12 connection exhaust system that form while utilizing 1 injection moulding of rubber suspension member and the suspension hook (not shown) on vehicle body, whole exhaust system is connected with the dontake pipe (not shown) of driving engine by flange 22.
