The gas handling system of type cannot have a prodigious installation space as earth's surface engineering truck, and the air inlet of some ground vehicles at present
At the higher and middle position positioned at vehicle-width direction of system position, pilot's line of vision is influenced；Meanwhile the prior art is also
It is longer that there are exhaust elbows, the defects of increasing exhaust resistance, while being inconvenient to repair.
Utility model content
The purpose of this utility model is to provide a kind of air inlet system and exhaust system of underground transportation vehicle front engine, reduce into
Exhaust system component blocks driver's sight.
A kind of underground transportation vehicle front engine air inlet system and exhaust system, including gas handling system and exhaust system, air inlet system
System includes air cleaner, and air cleaner is connected to through air inlet pipeline in turbocharger successively, and air cleaner is located at vehicle
Body side is located at the visual field lower section of driver close to driver's cabin front apron and height.
In above-mentioned technical proposal, air cleaner is arranged in Vehicular side body and height is also defined, it is ensured that is driven
The visual field for the person of sailing meets the basic demand of safe driving.
Description of the drawings
Fig. 1 is the dimensional structure diagram of the utility model；
Fig. 2 is the side view of vehicle.
Specific implementation mode
In conjunction with Fig. 1,2, the utility model is made further instructions：
A kind of underground transportation vehicle front engine air inlet system and exhaust system, including gas handling system 10 and exhaust system 20, into
Gas system 10 includes air cleaner 11, and air cleaner 11 is connected to through air inlet pipeline in turbocharger 30 successively, air
Filter 11 is located at the visual field lower section that Vehicular side body is located at driver close to driver's cabin front apron and height.
In conjunction with Fig. 2, before the following boundary line of the sight of so-called driver is exactly in fact the sight to vehicle of driver
The face where line between end pieces highest point generally can be regarded as forward position position and the mesh of driver of cabin cover 41
Face where line between light, thus the utility model be exactly by air cleaner 11 and air inlet be arranged in vehicle side and
At position to the rear, it can thus expand the field range of driver.
Exhaust system 20 includes exhaust gas sound-deadening clarifier 21, and exhaust gas sound-deadening clarifier 21 is connected to turbine by gas exhaust piping and increases
On depressor 30, exhaust gas sound-deadening clarifier 21 is arranged in the opposite body side in 11 place side of air cleaner and is located at front-wheel rear.
The arrangement for avoiding influencing other components in the case of exhaust is normal is ensured that in this way, makes cabin space by scientific and reasonable profit
With.
Air inlet pipeline includes the silica gel pipe fitting 12 being connected with air cleaner 11 and pipe joint in middle 14, the first air inlet
One end of bend pipe 13 is connected with silica gel pipe fitting 12, the other end is connected with pipe joint in middle 14, one end of the second intake elbow 15
Be connected with pipe joint in middle 14, the other end is connected in turbocharger 30, the pipe shaft of the second intake elbow 15, which is horizontally placed on, to be started
Above 40 front end of machine and pipe range direction is consistent with vehicle-body width direction on the whole, the first intake elbow 13 from back to front, from export-oriented
Introversive longitudinal 40 position of engine is disposed to extend.
Successively by exhaust elbow 22,23 phase of bellows between the turbocharger 30 and exhaust gas sound-deadening clarifier 21
Even, bellows 23 is along from inside to outside, mode is arranged from top to bottom.
Above-mentioned specific arrangement can improve the bending angle at the bend pipe position in airflow pipeline, objectively reduce
Flow resistance, it is ensured that air-flow is unobstructed, for the bent angle of bend pipe, is all higher than right angle, is mostly 120 °~150 °.
Air cleaner 11 and exhaust gas sound-deadening clarifier 21 are mounted on by the first and second mounting base 50,60 on vehicle body respectively.
The gas handling system of above-mentioned technical proposal also helps the filter element replacing of air cleaner 11, by this air cleaner 11
Outermost end replace filter core and dispose in vehicle left side, but not ultra-wide, there are inspection sockets here for rack, are convenient for changing filter core.Together
When pay attention to from 40 air inlet of engine to the air inlet pipe in 11 exit of air cleaner arrange, as possible ensure be close on engine 40
Edge avoids the sight blind area for increasing driver to reduce increased height herein.Intake elbow is minimized on this basis
Bending degree, to reduce intake resistance.Under conditions of meeting above-mentioned requirements, ensure the accuracy of design, using support platform,
By air cleaner fixation i.e. the first mounting base 50, it is mounted on vehicle body.
