Description

The low-floor bus of the integrated layout of a kind of air receiver level

Technical field

The utility model relates to low-floor bus, relates in particular to the low-floor bus of the integrated layout of a kind of air receiver level.

Background technology

Existing low-floor bus generally adopts chassis and the air braking system more than 10 meters on the market, its engine at extreme rear, and the car load floor level of this low-floor bus is lower, and 350 millimeter can realize that zero level marks time.Owing to be subjected to the restriction of car load floor level, vehicle-mounted air receiver is as the closed-center system of air braking system, and under the restriction of 40 liters of each air receiver volumes or 20 liters and fixture structure, it arranges the main following dual mode that adopts:

First kind is with the afterbody of air receiver centralized arrangement at car load, (sees shown in Figure 1) on the machinery space.What this kind arrangement at first caused air braking system needs air receiver from the machinery space guide the drg of forward and backward bridge into gas, prolonged the brake system reaction time, secondly air receiver has taken the space on machinery space top, makes the car load rear portion can't arrange seat, causes waste.

Second kind be with the air receiver centralized arrangement on the plane on car load floor, (see shown in Figure 2) between the forward and backward bridge.This kind arranged air receiver between forward and backward axle, and the brake system reaction time is faster than first kind of scheme, but has taken the space of passenger zone, and has reduced the seat number, is unfavorable for that car load is attractive in appearance.

Summary of the invention

The purpose of this utility model is that the air receiver layout takies the car load space in the above-mentioned background technology in order to solve, and may influence the problem in brake system reaction time, propose that a kind of to take the car load inner space few, simple and compact for structure, do not influence the low-floor bus of the integrated layout of air receiver level in brake system reaction time.

For achieving the above object, the utility model adopts following technical scheme: the low-floor bus of the integrated layout of a kind of air receiver level, being included as this passenger vehicle air braking system provides the air receiver of source of the gas, it is characterized in that described air receiver horizontally is fixed on it under bus deck on the vehicle frame between the forward and backward axle by the air receiver anchor fitting.

Described air receiver is preferably between the longeron of vehicle frame or between the crossbeam.

The external diameter of described each air receiver is preferably smaller or equal to 180 millimeters.

In such scheme, described air receiver anchor fitting comprise support boatswain chair and for air receiver support locate on the boatswain chair the air receiver support, and can be with the band of air receiver tighten on the air receiver support, described air receiver support is fixed on and supports on the boatswain chair, the two ends of band are connected with the support boatswain chair, support boatswain chair and connect to ground.

Above-mentioned support boatswain chair can be positioned at below the vehicle frame, and it links to each other with bolt with welding support with the vehicle frame weld together.

The above band with support that the most handy black nut is connected between the boatswain chair.

Above-mentioned each row's air receiver has two and supports boatswain chair.

In sum, the beneficial effects of the utility model are as follows:

Air receiver described in the utility model utilize the air receiver anchor fitting with its integrated layout, be positioned under the car load floor in the sheaf space between the forward and backward axle, take car load arrangement space and carrying space no longer in addition, it is compact, attractive in appearance to make complete vehicle structure arrange.

Be arranged between the forward and backward axle of car load because air receiver is integrated, so air receiver obtains shortening to the distance of forward and backward bridge drg, help accelerating brake response time.

Air receiver is integrated to be arranged in the idle space between the forward and backward axle and the air receiver position basically identical of common vehicle, and it is approaching to be convenient to the maintainer, easy accessibility.

The air receiver fixture structure is simple, and easy accessibility helps the maintenance and the dismounting of air receiver.

In sum, the utility model can solve in the background technology low-floor bus air receiver arrange in piping layout long, take the problem of car load available space, can optimize the car load inner space and arrange, help controlling cost.

The specific embodiment

Referring to Fig. 3, Fig. 4 and Fig. 5, the low-floor bus of the integrated layout of a kind of air receiver level described in the utility model, being included as this passenger vehicle air braking system provides the air receiver 1 of source of the gas, described air receiver 1 by air receiver anchor fitting 3 with its level, be arranged in parallel within the bus deck between the forward and backward axle between the longeron of vehicle frame 2 or in the sheaf space between the crossbeam, and be fixed on the vehicle frame 2.

The described air receiver anchor fitting 3 of present embodiment is made up of air receiver support 9, band 7, support boatswain chair 5 and welding support 10.Wherein, welding support 10 is welded direct on the vehicle frame 2, and air receiver support 9 is welded on and supports on the boatswain chair 5, supports between boatswain chair 5 and the welding support 10 to be connected by bolt of rear end plate, nut 4, support boatswain chair 5 and be positioned at below the vehicle frame 2, be connected by black nut 6 between the two ends of band 7 and the support boatswain chair 5.

Air receiver 1 is placed on the air receiver support 9 that supports on the boatswain chair 5, by band 7 tightens.

The volume of each air receiver 1 is 15 liters, and diameter is 180 millimeters.Connect with pipeline 8 between each air receiver 1, form and meet the energy storage volume that the brake system loop requires.

Air receiver 1 described in the utility model and air receiver anchor fitting 3 are with reference to existing technology manufacturing, and simple in structure, easy accessibility helps cost control.

Although embodiment has made detailed description to the utility model; but people can also make the modification that does not depart from its central idea to it; as air receiver is parallel, be staggered; or select the air receiver anchor fitting of other version for use; these modifications all belong to protection domain of the present utility model, and protection domain of the present utility model should be as the criterion with claims.
