Abstract

The utility model relates to an improved pneumatic door for a bus, which is characterized in that the door is a non-folding integral door leaf which is provided with a single leaf or is folio. The opening end of the door is provided with a slide block which is fixedly connected with the opening end of the door, and the slide block is arranged in a slide way behind the door. A swing arm on a swing shaft at the outer side in the other end of the door is connected with a pull-push rotary shaft on the door, and therefore, a movable draw arm of the swing arm is connected with a piston rod of a driving cylinder. After the door which is pulled by the swing arm is opened, the door can not be folded and is stopped at the outer side in a door frame, which is convenient for passengers to get on and out of the bus. When the door is closed, the door is flat with the appearance of a bus body, which has the advantages of beautiful appearance and small wind resistance.

Description

A kind of passenger vehicle pneumatic type car door

The utility model relates to passenger door, particularly a kind of passenger vehicle pneumatic type car door.

Existing medium-sized, motor omnibus is passenger's car door up and down, mostly adopts the pneumatic type car door, and promptly to drive cylinder through drive disk assembly push-and-pull car door, car door is generally collapsible, opens and closes along the slideway on the last lower door frame is folding.The shortcoming of this collapsible pneumatic car door is: after the folding unlatching of car door, tie up the doorframe space, reduced the Effective width of door opening, it is very inconvenient that the rider is got on or off the bus; In addition, during for fear of car door opening, the unlikely vehicle body that stretches out of folding door leaf, the car door slideway can only be contracted places in the car, like this, and during closing of the door, the door leaf indent, neither attractive in appearance, windage is also big.

The purpose of this utility model does not reduce the wide open width of car door after a kind of unlatching will be provided exactly, and this is neat to close back and vehicle body, the passenger vehicle pneumatic type car door that windage is little.

For this reason and design-calculated passenger vehicle pneumatic type car door, form by driving cylinder, drive disk assembly and car door, car door is not folding whole door leaf, the car door opening end has with it, and the slide block of captive joint places among the slideway, swing arm on the about side-sway axle of the car door other end links to each other with the push-and-pull rotating shaft on the car door, and the torque arm of balance staff motion is linked to each other with the piston rod that drives cylinder.

After the utility model passenger door was opened, car door was not folding, does not increase thickness, and parked in the about side of door frame, made the wide open width of car door not reduce favourable passenger getting on/off.

The two-leafed door that the folding whole door leaf of the utility model passenger vehicle pneumatic type car door can be single door or splits, because slideway can be arranged on behind the door, so door leaf can be concordant with bodywork surface during closed condition, thereby both guaranteed can reduce windage again by the attractive in appearance of car load.

Embodiment describes the utility model below in conjunction with accompanying drawing.

Fig. 1 is the biparting clamshell type passenger vehicle of a utility model embodiment pneumatic type car door scheme of maneuver.

Fig. 2 is Fig. 1 pneumatic type car door pneumatic part scheme drawing.

As shown in Figure 1 and Figure 2, the door leaf of the utility model passenger vehicle pneumatic type car door is not folding whole door leaf 3, its opening end has with it, and the slide block 2 of captive joint places among the slideway 1, swing arm 5 on the balance staff 8 in the other end outside links to each other with the push-and-pull rotating shaft 4 that does not fold on the whole door leaf 3, and the torque arm 9 of balance staff 8 motions is linked to each other with the piston rod that drives cylinder 11.When opening the door, the piston rod 10 that drives cylinder 11 promotes torque arm 9, balance staff 8 is clockwise rotated, drive the swing of swing arm 5 cws, cannot not making foldingly integral door 3 is in the fulcrum bogie car with slide block 2, slide block 2 moves to right along slideway 1 simultaneously, and outside doorframe 6, car door is wide open fully until not folding whole door leaf 3 sides.Otherwise, close the door.After door was closed, not folding whole door leaf 3 was concordant with vehicle body 7 appearances.

Claims

1, a kind of passenger vehicle pneumatic type car door, form by driving cylinder, drive disk assembly and car door, it is characterized in that said car door is not folding whole door leaf, the car door opening end has with it, and the slide block of captive joint places among the slideway, swing arm on the about side-sway axle of the car door other end links to each other with the push-and-pull rotating shaft on the car door, and the torque arm of balance staff motion is linked to each other with the piston rod that drives cylinder.

2, passenger vehicle pneumatic type car door according to claim 1, it is characterized in that said folding whole door leaf be single fan formula split biparting, door leaf is concordant with bodywork surface during closed condition, during full-gear, car door places outside the door frames.
