Abstract
The utility model relates to an exhaust muffler of a motorcycle, which comprises a muffler and an exhaust pipe connected with the muffler, wherein the muffler is provided with an outer cylinder and an inner pipe; catalyst is installed in the exhaust muffler; the exhaust pipe is connected with the muffler through a transition pipe; one end of the transition pipe is welded with space between the outer cylinder and the inner pipe of the muffler and is fixedly connected with the muffler, and the other end is fixedly welded with an outer thread sleeve; one end of the exhaust pipe is fixedly welded with a lining sleeve and is sheathed with an inner thread sleeve, and the inner thread sleeve is connected with the outer thread sleeve in a screwing mode; the catalyst is placed in the transition pipe. The exhaust silencer has the advantages that the exhaust pipe and the muffler are easy to disassemble, and thus, the disassembly and the replacement of the catalyst in the exhaust muffler are convenient; when the catalyst is abandoned, only the catalyst needs to be replaced, and the exhaust muffler can continue to be used, and thus, the waste of resources can not be caused.
Description
Technical field
The utility model relates to a kind of exhaust muffler for motorcycle.
Technical background
Exhaust muffler for motorcycle is the device that is used to handle the motorcycle engine toxic emission, to reduce noise and the toxic emission pollution on the environment that motor produces.Exhaust silencer is formed by connecting by outlet pipe and silencing apparatus, and in outlet pipe or silencing apparatus catalyst is installed, and catalyst is that the centre is cellular cylindrical body, is used for the purifying engine exhaust gas discharged.In the motorcycle using process, because working life that is far longer than catalyst working life of exhaust silencer, so often when exhaust silencer still can normally use, catalyst has been scrapped and can not normally have been used.And because existing exhaust silencer, its outlet pipe and silencing apparatus are connected as a single entity by welding, thereby the catalyst of scrapping can not be taken out in exhaust silencer, like this because the scrapping of catalyst, and cause whole exhaust silencer to be scrapped, and this moment, silencing apparatus did not also reach working life far away, so the structure of existing exhaust silencer has caused the significant wastage of resource.
The model utility content
Technical problem to be solved in the utility model provides a kind of exhaust silencer, makes the catalyst that is installed in the exhaust silencer can retract replacing easily.
Exhaust silencer described in the utility model, comprise silencing apparatus with urceolus and interior pipe, and the outlet pipe that is connected with silencing apparatus, catalyst is installed in exhaust silencer, outlet pipe is connected with silencing apparatus by excessively managing, excessively Guan Yiduan is welded between silencing apparatus urceolus and the interior pipe and fixedlys connected with silencing apparatus, excessively the pipe the other end is welded with external thread sleeve, outlet pipe one end is welded with lining, and be set with inner screw sheath, and inner screw sheath and described external thread sleeve spin, and outlet pipe and excessive pipe are fastenedly connected, and described catalyst is positioned at excessive pipe.
The endoporus that is welded on the external thread sleeve of the excessive pipe the other end is a step hole, and the lining that is welded on outlet pipe one end is arranged in this endoporus, is provided with seal ring between bush end face and the external thread sleeve endoporus step surface.
Its silencing apparatus of exhaust silencer described in the utility model and outlet pipe connect as one by excessive pipe, and being connected of outlet pipe and excessive pipe is that inner screw sheath and spinning of the external thread sleeve that is welded on excessive pipe end on the outlet pipe realize by being sleeved on, make outlet pipe and excessive pipe be easy to dismounting, thereby be convenient to the dismounting and change of catalyst in the exhaust silencer.When catalyst is scrapped, only need to change catalyst, exhaust silencer still can continue to use, so can not cause the waste of resource.And this kind Placement of the utility model outlet pipe and silencing apparatus, can not make exhaust silencer at outlet pipe and silencing apparatus weld owing to phenomenon of rupture appears in large-area weld seam, promoted the quality of product of exhaust silencer.Owing between bush end face and external thread sleeve endoporus step surface, be provided with seal ring, can prevent effectively that waste gas from leaking from outlet pipe and silencing apparatus joint.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 looks generalized section for the master of exhaust silencer described in the utility model;
Fig. 2 is the enlarged view at M position among Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, this exhaust silencer comprises the silencing apparatus with urceolus 9 and interior pipe 8, and the outlet pipe 1 that is connected with silencing apparatus, catalyst 6 is installed in exhaust silencer, outlet pipe 1 is connected with silencing apparatus by excessive pipe 7, excessively pipe 7 one ends are welded between silencing apparatus urceolus 9 and the interior pipe 8 and fixedly connected with silencing apparatus, excessively manage 7 the other ends and are welded with external thread sleeve 4, and the endoporus of external thread sleeve 4 is a step hole.Outlet pipe 1 one ends are welded with lining 3, and be set with inner screw sheath 2, the interior threaded hole of inner screw sheath 2 also is a step hole, be that inner screw sheath has step ledge 10 in the circle, lining 3 is arranged in the endoporus of external thread sleeve 4, is provided with seal ring 5 between lining 3 end faces and the external thread sleeve 4 endoporus step surfaces, and inner screw sheath 2 spins with described external thread sleeve 4, the interior step ledge 10 of inner screw sheath 2 acts on the lining 3, and outlet pipe 1 and excessive pipe 7 are fastenedly connected.Described catalyst 6 is installed in the excessive pipe 7, between pipe 8 end faces and the seal ring 5, moves axially along excessively managing 7 with restriction catalyst 6 in silencing apparatus.
