Description
Technical field
The utility model belongs to industrial vehicle technical field, relates in particular to a kind of vehicle exhaust system structure and has its fork truck.
Background technique
Existing fork truck vehicle exhaust system structure is generally comprised of outlet pipe, U-shaped clip, silencing apparatus, is connected, as shown in Figure 2 between outlet pipe and silencing apparatus with U-shaped clip.
Existing vehicle exhaust system structure shortcoming is as follows: 1, between outlet pipe and silencing apparatus, with U-shaped clip, be fixed, easily gas leakage, causes outlet pipe and silencing apparatus by sooting.2, integrated type acoustic wave filter structure is complicated, makes difficulty, is not easy to guarantee critical size; 3, silencing apparatus two side supports adopt dissymmetrical structure, and tailstock in vehicle frame can not be unified, to production, make troubles, and silencing apparatus employing monolithic construction, also make troubles to logistics.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of difficult gas leakage, manufacture vehicle exhaust system structure easy for installation and have its fork truck.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of vehicle exhaust system structure, comprise silencer cylinder, described silencer cylinder is provided with the first connecting tube, described the first connecting tube end is provided with flange, silencer cylinder is connected with the flange on outlet pipe assembly by the flange of the first connecting tube end, also comprise muffler tail pipe, described muffler tail pipe and silencer cylinder are split-type structural, described muffler tail pipe and silencer cylinder removably connect, described silencer cylinder is provided with the second connecting tube, described the second connecting tube end is provided with flange, described muffler tail pipe end is also provided with flange, described muffler tail pipe is connected by flange with silencer cylinder, the first connecting tube and second connecting tube at silencer cylinder two ends are symmetrical.
A fork truck, comprises fork truck body, on described fork truck body, has above-mentioned vehicle exhaust system structure.
A technological scheme tool in technique scheme has the following advantages or beneficial effect, flange by the first connecting tube on silencer cylinder is connected with the flange of outlet pipe assembly, and the first connecting pipe structure is simple, and the manufacture of being convenient to silencer cylinder is installed, by flange, connect, be difficult for gas leakage.Adopt the fork truck of above-mentioned vehicle exhaust system structure also to there are these advantages.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of vehicle exhaust system structure of the utility model;
Fig. 2 is prior art structural representation;
Mark in above-mentioned figure is: 1, silencer cylinder, the 2, first connecting tube, the 3, second connecting tube, 4, outlet pipe assembly, 5, pad, 6, muffler tail pipe.
Embodiment
Fig. 1 is the structural representation of a kind of vehicle exhaust system structure of the utility model, comprise silencer cylinder 1, silencer cylinder 1 is provided with the first connecting tube 2, the first connecting tube 2 ends are provided with flange, and silencer cylinder 1 is connected with the flange bolt on outlet pipe assembly 4 by the flange of the first connecting tube 2 ends.
Between the flange of the first connecting tube 2 ends and the flange on outlet pipe assembly 4, be provided with the pad 5 that prevents gas leakage.The first connecting tube 2 is straight tube.Between silencing apparatus and outlet pipe, adopt flange arrangement and the middle pad 5 that adopts to prevent gas leakage.The first connecting tube 2 is a bit of straight tube on silencer cylinder 1, and the manufacture of being convenient to silencing apparatus is installed.
Also comprise muffler tail pipe 6, muffler tail pipe 6 is split-type structural with silencer cylinder 1, removably connects.Former muffler assembly is divided into silencer cylinder 1 and 6 two parts of muffler tail pipe, assembling after manufacturing separately.Changed the complicated shape of former silencer cylinder 1 and muffler tail pipe 6 integral structures; Silencer cylinder 1 and muffler tail pipe 6 be packed and transported separately, solves silencing apparatus logistics difficult problem.
Silencer cylinder 1 is provided with the second connecting tube 3, the second connecting tube 3 ends and is provided with flange, and muffler tail pipe 6 ends are also provided with flange, and muffler tail pipe 6 is connected by flange with silencer cylinder 1, prevents gas leakage.
The second connecting tube 3 is a bit of straight tube.Regular shape, is convenient to manufacture.
The first connecting tube 2 and second connecting tube 3 at silencer cylinder 1 two ends are symmetrical.The first connecting tube 2 and the second connecting tube 3 are highly symmetrical, can replace use, manufacture while installing and do not need to distinguish two connecting tubes, convenient manufacture, convenient production; The first connecting tube 2 and the second connecting tube 3 are symmetrical, make the support of silencing apparatus both sides also symmetrical, and in vehicle frame, tailstock can be unified, and is convenient to the processing of tailstock.
A fork truck, comprises fork truck body, has above-mentioned vehicle exhaust system structure on fork truck body.
Adopt after above-mentioned structure, original outlet pipe end face is adopted to flange arrangement, outlet pipe and silencing apparatus adopt pad 5 to carry out leakproof while installing, silencing apparatus is divided into silencer cylinder 1 and muffler tail pipe 6 on original basis, silencer cylinder 1 two ends adopt flange and highly symmetrical, silencer cylinder 1 carries out leakproof with muffler tail pipe 6 joints with pad 5, and convenient installation, conveniently produces, facilitates logistics.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or without improving, design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
