Abstract
The utility model discloses a door shaft assembly for a bus. Axial positioning grooves are formed in the positions, where two bending arms are located, on the periphery of a main shaft in the door shaft assembly for the bus, connecting blocks are embedded and fixed inside the two axial positioning grooves respectively in a welding mode, the two connecting blocks are respectively provided with a bending arm installation surface, the two bending arm installation surfaces are located on the same plane parallel with the length direction of a door shaft, and the two bending arms are detachably fixed to the bending arm installation surfaces on the corresponding connecting blocks and connected through bolts or screws. Therefore, on the premise of guaranteeing reliable connection between the connecting blocks and the door shaft assembly, the relative positions of the two bending arms are determined by the positions of the two axial positioning grooves formed in the main shaft, namely on the premise of guaranteeing that the two bending arms are easily and reliably assembled on the main shaft, the installation accuracy of the two bending arms on the main shaft is improved at the same time.
Description
Technical field
The utility model relates to a kind of passenger vehicle door-hinge assembly.
Background technology
At present, passenger vehicle on market (as bus, long-distance big bus etc.) generally adopts pneumatic folding door, be subject to pneumatic driving pump pulling force and the impact of the factors such as frequent switch gate action of getting on or off the bus, the door-hinge assembly being connected between car door and vehicle frame easily deforms, affect the normal use of passenger vehicle, wherein on door-hinge assembly, the installation site of two curved booms of L-type on main shaft seems particularly important to the impact of the switch motion of car door.And in prior art, two common modes with bolts of curved boom are connected on main shaft, while offering corresponding bolt penetration hole like this on main shaft, need to the position in hole, position each bolt, to guarantee that two morpheme errors between curved boom meet the requirements, thereby the difficulty that has improved the processing of door-hinge assembly and assembling, has reduced operating efficiency.
Utility model content
The purpose of this utility model is to provide a kind of passenger vehicle door-hinge assembly of being convenient to assembling in the situation that guaranteeing two curved boom installation accuracies.
In order to realize above object, passenger vehicle of the present utility model is as follows by the technical scheme of door-hinge assembly:
A kind of passenger vehicle door-hinge assembly, comprise main shaft and on spaced two curved booms along its length, in the periphery of described main shaft, in place, two curved boom present positions, be provided with axial location groove, in two axial location grooves, be embedded to be respectively welded and be fixed with contiguous block, on two contiguous blocks, correspondence is provided with the curved boom installed surface on the same plane parallel with door-hinge length direction, and described two curved booms are bolted respectively or screw connects the removable curved boom installed surface being fixed on corresponding contiguous block.
Described contiguous block and curved boom are bolted fixing, offer circular hole or circular hole for screw for bolt, on another, correspondence offers slotted hole or the screw slotted hole for bolt with the parallel distribution of axial location groove in one of them of contiguous block and curved boom.
The described contiguous block vertically bearing of trend of locating slot overhangs.
The two ends of described main shaft are equipped with along its length the connecting hole extending, and in one of them of two connecting holes, interference is equipped with power transmission shaft, is equipped with bearing on another.
Described power transmission shaft is the splined shaft for being in transmission connection with drive unit key.
Described power transmission shaft is welded on connecting hole, on the hole wall of the connecting hole corresponding with power transmission shaft, offers plug welding hole.
The body that the curved boom body, curved boom body that described curved boom comprises L-type is connected away from one end of main shaft, the bearing of trend of described body and the bearing of trend of main shaft are parallel to each other.
The utility model offers the axial location groove with the corresponding setting of two curved booms difference in the periphery of main shaft, in each axial location groove, all coincide to be embedded and be fixed with contiguous block, each contiguous block is connected with corresponding curved boom again, so that curved boom is connected on the axial location groove of offering on main shaft by contiguous block, thereby guaranteeing that contiguous block is connected in reliable situation with door-hinge assembly, make the relative position of two curved booms by the determining positions of two axial location grooves that arrange on main shaft, in the situation that guarantee two simple and reliable being assemblied on main shaft of curved boom, improved the installation accuracy of two curved booms on main shaft simultaneously.Meanwhile, because of in use easily wearing and tearing of curved boom, so curved boom is with bolts with contiguous block or screw is connected and realizes curved boom and can pull down from contiguous block, so that change curved boom.
Further, at the two ends of main shaft, interference is equipped with power transmission shaft and bearing respectively, to guarantee that by interference fit power transmission shaft and lower end are coaxially assemblied on main shaft, guarantee that car door is in open and close process, door-hinge assembly can guide car door to rotate according to desired trajectory smoothly, has improved the smoothness of open and close door action.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
The embodiment of door-hinge assembly for passenger vehicle of the present utility model: as shown in Figure 1, this passenger vehicle comprises contiguous block 2, curved boom 3, power transmission shaft 4 and the lower end 5 of canular main shaft 1 and upper assembling thereof with door-hinge assembly, on main shaft 1, offer two spaced axial location grooves vertically, two axial location grooves are parallel to each other along same radially extension, in each axial location groove, be embedded respectively and be welded with a contiguous block 2, the contiguous block 2 vertically bearing of trend of locating slot extends, and has all been bolted curved boom 3 on each contiguous block 2.On contiguous block 2, offer bolt circular hole, on curved boom 3, offer and bolt slotted hole corresponding to circular hole for bolt, the bar portion of fastening bolt penetrate bolt with in circular hole, head be buckled in bolt use slotted hole hole along upper.
The endoporus section at main shaft 1 two ends is connecting hole section, and power transmission shaft 4 and lower end 5 respectively interference are assemblied in two connecting hole sections, and power transmission shaft 4 splined shaft for being in transmission connection with drive unit key, lower end 5 for rotate be assemblied on vehicle frame with ball bearing.And offering respectively plug welding hole on the hole wall of the connecting hole section at power transmission shaft place, plug welding hole has three, and equal axial middle part in connecting hole section, to come reinforced company's spindle and lower end 5 to be connected in the bonding strength on main shaft 1 by plug welding.
Curved boom 3 forms by the curved boom body 31 of L-type and away from the body 32 that one end welding of main shaft 1 is connected, and the bearing of trend of the bearing of trend of body 32 and main shaft 1 is parallel to each other.
In the above-described embodiments, power transmission shaft is splined shaft, in other embodiments, and the gear shaft that power transmission shaft also can be connected with gear drive, the sprocket shaft being connected with chain gear transmission etc.
