Structural arrangement system of ahead driving region in air-conditioning state of 18-m rapid bus

Abstract

The invention relates to a structural arrangement system of an ahead driving region in an air-conditioning state of an 18-m rapid bus. A floor frame from a front door passenger zone to a driving zone is in a concave floor structure which is one step higher than the passenger zone, the left side and the right side of the concave floor structure are respectively provided with two passenger seats facing to the middle, an openable movable guardrail is arranged in front of the passenger seats, and the front-middle part of the movable guardrail is provided with an engine cover of which the bottom is in a Z-shaped high-low structure; the right side of an engine is respectively provided with a power steering oil holder, a defroster, an auxiliary water tank and a compressor from the front to the back, wherein an overhaul box is arranged at the upper parts of the defroster, the auxiliary water tank and the compressor and is divided into a front space and a rear space which are respectively provided with an overhaul door, the front overhaul door corresponds to the defroster and the auxiliary water tank, and the rear overhaul door corresponds to the compressor; and a bus body framework in front of a right front wheel is provided with a rapid overhaul door for tensioning and overhauling the compressor, and the rear part of the right front wheel is provided with an air filter arranged in the middle of an air inlet of the engine and an air inlet of a bus body.

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...

[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
