Front-mounted 18-meter rapid bus air-conditioning state driving area structural layout system

Abstract

The invention relates to a structural layout system for the driving area of ​​an 18-meter express bus in the air-conditioned state. The floor frame from the passenger area at the front door to the driving area is a concave floor structure with one step higher than the passenger area. Two passenger seats facing the middle are arranged on both sides, and movable guardrails that can be opened are arranged in front of the passenger seats, and an engine cover with a Z-shaped high-low structure is installed at the front and middle of the movable guardrails; Turn to the oil pot, defroster, auxiliary water tank and compressor, and install an inspection box on the upper part of the defroster, auxiliary water tank and compressor. The inspection box is divided into two spaces, front and rear, and each has its own inspection door. The defroster corresponds to the auxiliary water tank, and the rear access door corresponds to the compressor; the body frame at the front of the right front wheel has a quick access door for tightening and repairing the compressor, and the air filter is arranged at the rear of the right front wheel , the air filter is located in the middle of the engine air intake and the body air intake.

Description

technical field [0001] The invention relates to a structural arrangement system, in particular to a structural arrangement system for the air-conditioned driving area of ​​a front-mounted 18-meter express bus. Background technique [0002] At present, domestic 18-meter front-mounted models have a large market in Beijing, Taiyuan and other places. However, due to the tight space in the driving area of ​​front-mounted vehicles and difficult layout, none of the domestic 18-meter front-mounted models are equipped with non-independent air conditioners. With the economic level of our country With the development of modern vehicles and the improvement of people's lives, the voice of installing air conditioners on 18-meter-front models is getting higher and higher. Due to the influence of the upper limit of the front axle load of existing 18-meter-front models in China, the front overhang length is generally controlled within 2 meters. The widest width of the whole vehicle is only 2...

Problems solved by technology

[0002] At present, domestic 18-meter front-mounted models have a large market in Beijing, Taiyuan and other places. However, due to the tight space in the driving area of ​​front-mounted vehicles and difficult layout, none of the domestic 18-meter front-mounted models are equipped with non-independent air conditioners. With the economic level of our country With the development of modern vehicles and the improvement of people's lives, the voice of installing air conditioners on 18-meter-front models is getting higher and higher. Due to the influence of the upper limit of the front axle load of existing 18-meter-front models in China, the front overhang length is generally controlled within 2 meters. The widest width of the whole vehicle is only 2.55 meters. In this space, it is necessary to arrange the driving area reasonably and to consider the installation position of the chassis accessories. The maximum cooling capacity of the 18-meter air conditioner is required to be 53320Kcal / h , it is obviously extremely difficult to arrange a 6-cylinder piston compressor in the case of tight space, which is also an important reason why there has been no 18-meter front-mounted air-conditioned vehicle in China
