Abstract
The utility model provides a kind of air inlet system of forklift engine, comprise the air filter on the upper cover plate top being located at Engine Casing and connect the suction tude of air filter and motor, described suction tude is arranged with the first flange, the side of described upper cover plate is installed with the second flange, the upper cover plate being positioned at the second flange center hole site offers pore, first flange through the both sides that described pore makes the first flange, the second flange is positioned at upper cover plate, and is connected with the second flange by bolt by described suction tude one end.By the first flange, the second Flange joint between suction tude and upper cover plate, and by the gap in the flange face sealing suction tude of the first flange and upper cover plate between pore, thus avoid noise in Engine Casing and radiate from this, namely reduce the level of noise of air inlet system; Add the immovable point of suction tude simultaneously, effectively reduce the impact on engine turbine pressure-increasing machine by system gravity and vibration of former gas handling system.
Description
Technical field
The utility model relates to fork truck technical field, is specifically related to a kind of air inlet system of forklift engine.
Background technique
Along with the high speed development of modern industry, the logistics transportation instrument that fork truck is important in producing as current modern industry, application is more and more extensive, and application working environment also becomes increasingly complex, therefore it is also proposed more and more higher requirement to safe, intelligent, the travelling comfort etc. of fork truck.The states such as wherein noise pollutes as one, has been subjected to increasing concern, American-European have all formulated strict noise emission standards.
In air, large granular impurity is to motor generation wearing and tearing and to its performance impact, generally add air filter at engine charge end, air filter need be arranged in the upper cover plate upper end of Engine Casing, is connected after causing the suction tude of motor to need the upper cover plate through Engine Casing with air filter again.Therefore upper cover plate needs to hold the circular hole for through suction tude in advance successfully, and consider manufacture and assembly error, need this circular hole to be opened want large a lot of relative to the external diameter of suction tude, this by cause the work of hood internal engine to produce noise just by the gap leakage between the circular hole in suction tude and upper cover plate in external fuselage, complete machine level of noise is exceeded standard.
Model utility content
The purpose of this utility model is just to provide a kind of air inlet system of forklift engine, thus achieves the noise reducing motor.
The technical solution of the utility model is: a kind of air inlet system of forklift engine, comprise the air filter on the upper cover plate top being located at Engine Casing and connect the suction tude of air filter and motor, described suction tude is arranged with the first flange, the side of described upper cover plate is installed with the second flange, the upper cover plate being positioned at the second flange center hole site offers pore, first flange through the both sides that described pore makes the first flange, the second flange is positioned at upper cover plate, and is connected with the second flange by bolt by described suction tude one end.
Further scheme, the diameter of the center hole of described first flange is identical with the external diameter of described suction tude; The diameter of described pore is greater than the diameter of the center hole of described first flange, and is less than the diameter of the center hole of the second flange.
Further scheme, the periphery of described pore also offers bolt hole.
Further scheme, described second flange welding is in the bottom of upper cover plate, and the first flange is welded on suction tude periphery; First flange is connected with the second flange by bolt through described pore by the lower end of suction tude.
The first flange, the second Flange joint is passed through between suction tude and upper cover plate in the utility model, and by the gap in the flange face sealing suction tude of the first flange and upper cover plate between pore, thus avoid noise in Engine Casing and radiate from this, namely reduce the level of noise of air inlet system.In addition, to be arranged on by the first flange due to suction tude on the second flange on upper cover plate, thus to add the immovable point of suction tude, effectively reduce the impact on engine turbine pressure-increasing machine by system gravity and vibration of former gas handling system.
Conveniently install, the pore diameter offered at upper cover plate is greater than the diameter of the center hole of described first flange, and the diameter of the center hole of the second flange is greater than the diameter of pore, namely facilitates the assembling between suction tude and upper cover plate; In addition, because the diameter of the center hole of the first flange is less than pore diameter, thus the flange face sealing of the first flange has lived the gap between suction tude and pore, reduces noise and leaks.

In figure: 1-suction tude, 2-upper cover plate, 3-air filter, 4-first flange, 5-second flange, 6-bolt, 7-pore, 8-bolt hole.
Embodiment
As Figure 1-4, a kind of air inlet system of forklift engine, comprise the air filter 3 on upper cover plate 2 top being located at Engine Casing and connect the suction tude 1 of air filter 3 and motor, described suction tude 1 is arranged with the first flange 4, the side of described upper cover plate 2 is installed with the second flange 5, the upper cover plate 2 being positioned at the central hole location of the second flange 5 offers pore 7, and the periphery of pore 7 also offers bolt hole 8; Described suction tude 1 one end makes the first flange 4, second flange 5 be positioned at the both sides of upper cover plate 2 through described pore 7, and is coupled together through the first flange 4, bolt hole 8 and the second flange 5 successively by bolt 6.
Further scheme, the first flange 4 is welded on suction tude 1 periphery, and the diameter of the center hole of the first flange 4 is identical with the external diameter of suction tude 1; The diameter of described pore 7 is greater than the diameter of the center hole of the first flange 4 and is less than the diameter of the center hole of the second flange 5.Not only facilitate the assembling between suction tude 1 and upper cover plate 2, also make the flange face sealing of the first flange 4 live gap between suction tude 1 and pore 7, reduce noise and leak.
Further scheme, as shown in Figure 1, the second flange 5 is welded on the bottom of upper cover plate 2, and the first flange 4 is welded on suction tude 1 periphery; The lower end of suction tude 1 is connected with motor through pore 7, and the first flange 4 and the second flange 5 is coupled together through the first flange 4, bolt hole 8 and the second flange 5 successively from top to bottom by bolt 6.
