Exhaust system of large power forklift

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

[0001] technical field [0002] The invention relates to the field of high-power forklifts, in particular to an exhaust system for high-power forklifts. Background technique [0003] The function of the exhaust system is to discharge the high-temperature and high-noise exhaust gas produced by the engine combustion into the atmosphere after being silenced and reduced by the exhaust system, so as to reduce the noise pollution to the environment. Due to the fact that the appearance of forklifts is getting smaller and smaller, and the internal layout is relatively more and more compact, the layout of the exhaust system rich in high-temperature gas is relatively difficult. [0004] At present, on the exhaust of 10-ton forklifts, forklift manufacturers traditionally use the exhaust pipe to be arranged downward from the side of the engine, and the muffler is placed on the left side of the vehicle body, next to the rear of the fuel tank, and the exhaust The tail pipe discharges exh...

Problems solved by technology

As forklifts are getting smaller and smaller, and the internal layout is relatively more and more compact, the layout of the exhaust system rich in high-temperature gas is relatively difficult.

[0004] At present, on the exhaust of 10-ton forklifts, forklift manufacturers traditionally use the exhaust pipe to be arranged downward from the side of the engine, and the muffler is placed on the left side of the vehicle body, next to the rear of the fuel tank, and the exhaust The tail pipe discharges exhaust gas from the side of the counterweight, that is, the side of the steering wheel. The disadvantages are as follows: (1) The muffler is placed on the side of the car body and the rear of the fuel tank. Due to the limited lateral size, the exhaust pipe in the middle transition is too curved , increasing the exhaust resistance, which affects the power output of the engine; (2), the muffler is close to the fuel tank, which affects the distance between the high-temperature muffler and the fuel tank, and increases the risk factor of the forklift itself; (3), due to the muffler The position exists on the side of the fuel tank, occupying a part of the space on the left side, resulting in the space limitation of the fuel tank, which makes the continuous working time of one refueling limited; (4), because the exhaust tail pipe exhausts from the side of the steering wheel, the high temperature Exhaust gas blows to the steering wheel, accelerating the aging of tires and affecting the safety of the vehicle
