Abstract
The invention discloses an exhaust system of a large power forklift. The exhaust system of the large power forklift comprises an exhaust manifold, an exhaust pipe, a silencer and a tail pipe, wherein the exhaust manifold, the exhaust pipe, the silencer and the tail pipe are connected in order; the exhaust pipe is connected with the side part of the exhaust manifold in a parallel way; the silencer and the tail pipe are arranged on a vehicle body tail frame; the exhaust pipe is connected with the silencer through a connection pipe; and an air outlet of the connection pipe is upward. With the adoption of the exhaust system of the large power forklift, the exhaust system is rational in structure arrangement and better in exhaust effect; therefore, the consumption of engine power is decreased; moreover, the volume of an improved fuel oil tank is increased by 70%, i.e. the continuous working time is increased by 70% after one-time full-tank oil charge; and in addition, the service life of each steering tire is also prolonged by 2-5 times.
Description
Technical field
The present invention relates to high-power fork truck field, specifically a kind of high-power forklift truck exhaust system.
Background technology
The effect of exhaust system is the high temperature high noisy waste gas that will produce after the engine combustion work done, is discharged in the atmosphere behind the exhaust system sound-deadening and noise-reducing and goes, and reduces the noise pollution to environment.Because now the profile of fork truck is more and smaller and more exquisite, interior layout is also relative more and more compacter, so that be rich in the also difficulty relatively of layout of the exhaust system of high-temperature gas.
At present, fork truck manufacturing enterprise in the exhaust of 10 ton forklifts, more traditional employing be downward arranging exhaust air pipe from the side of driving engine, silencer is placed on the car body left side, adjacent fuel tank rear side, trail pipe be from the counterbalanced weight side, i.e. wheel flutter side discharging waste gas, its shortcoming is as follows: (1), noise silencer are placed on vehicle body side, the fuel tank rear side is because lateral dimension is limited, so that the freeing pipe camber of middle transition is excessive, increase resistance of exhaust, have influence on the power output of driving engine; (2), silencer is near fuel tank, has influence on the distance of silencer and the fuel tank of high temperature, raising fork truck self danger coefficient; (3), because the position of silencer is present in the fuel tank side, take the leftward space of a part, just cause the limitations of fuel tank, so that the stream time that once refuels is limited; (4), because trail pipe from the exhaust of wheel flutter side, so that high-temp waste gas blows to wheel flutter, accelerates the aging of tire, affect vehicle security.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of high-power forklift truck exhaust system, so that the exhaust of driving engine is more smooth and easy, space layout is more reasonable, under the prerequisite of reasonable noise reduction, can increase the volume of fuel tank, increase the stream time that once refuels, promote the life-span of fork truck part parts, improve the safety that car load uses.
Technical scheme of the present invention is:
A kind of high-power forklift truck exhaust system, include the dontake pipe, freeing pipe, silencer and the tail pipe that connect successively, the parallel sidepiece that is connected in dontake pipe of described freeing pipe, described silencer and tail pipe are arranged on the car body tailstock, described freeing pipe is connected with silencer by connection pipe, and the air extractor duct of connection pipe up.
Described connection pipe is set in parallel in the sidepiece of dontake pipe, and is connected with freeing pipe by clip.
Described connection pipe and silencer are by anulated connection.
Described silencer passes through
Rubber pad, bolt, nut, plain cushion and bullet pad are connected on the car body tailstock.
Described freeing pipe and connection pipe are all selected threaded line pipe.
Described freeing pipe is connected flange with dontake pipe and connects.
Advantage of the present invention:
(1), the present invention utilizes in the space that engine exhaust manifold makes progress without other parts, adopts upwards layout type backward, by freeing pipe, walks around water tank, through silencer waste gas is discharged; Reduce lateral dimension, increased the freeing pipe camber, reduced resistance of exhaust, reduced the impact on engine power, silencer is placed on car body back tailstock part, oil dropping apparatus is reserved enough large space, also reduce in addition high-temperature component near the danger of fuel oil, reduce high-temp waste gas to the impact of tire;
(2), freeing pipe of the present invention is connected by flange with engine exhaust manifold, the air extractor duct of freeing pipe links to each other with the silencer admission port again, silencer links to each other with the car body tailstock by parts such as bolt, nut, rubber pads, freeing pipe and connection pipe are bellows, are conducive to the adjustment of installation dimension;
(3), the present invention is simple in structure, daily attention is simple and convenient with cleaning.
Exhaust system structure connection and reasonable arrangement of the present invention, exhaust effect are better, have reduced the loss of engine power, and the volume of fuel tank will increase 70% after improving, and namely are once to fill it up with oily stream time to increase by 70%, and the life-span of steering tire also increases 2-5 doubly in addition.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
See Fig. 1, a kind of high-power forklift truck exhaust system, include the dontake pipe 1, freeing pipe 2, connection pipe 3, silencer 4 and the tail pipe 5 that connect successively, freeing pipe 2 is connected in the sidepiece of dontake pipe 1 by flange, the air extractor duct of freeing pipe 2 is connected with connection pipe 3 by the first clip 6a, the air extractor duct of connection pipe 3 is connected with tail pipe with the silencer 4 on being arranged at the car body tailstock up and by the second clip 6b and is connected, and silencer 4 is connected on the car body tailstock by rubber pad, bolt, nut, plain cushion and bullet pad 7; Freeing pipe 2 and connection pipe 3 are all selected threaded line pipe, and freeing pipe 2 and connection pipe 3 all are set in parallel in the sidepiece of dontake pipe 1, and connect by freeing pipe.
Because driving engine adopts rubber shock-absorbing with being connected of car body, silencer also is to adopt rubber shock-absorbing with being connected of car body, and freeing pipe, connection pipe do not contact with car body, so vibrations and abnormal sound that Vehicle Driving Cycle produces can additionally not be delivered in the exhaust system; Whole exhaust system design parameter requires its loss to engine power to be not more than 3.5%, and noise reduction is greater than 20dB.
Should be noted the leak tightness of whole exhaust steam passage in the installation process of the present invention, guarantee to form the gas channel of a sealing, waste gas is finally discharged from the silencer air extractor duct.
