Monorail train and horizontal axle assembly thereof

Abstract

The invention discloses a monorail train and a horizontal wheel shaft assembly thereof. The horizontal wheel shaft assembly comprises a horizontal wheel shaft, a first bearing and an oil deflector ring. The horizontal wheel shaft extends in the vertical direction and is sequentially provided with a first bearing mounting section and a second bearing mounting section from top to bottom. An oil outlet is formed in the peripheral surface of the horizontal wheel shaft, an oil filling port is formed in the lower end surface of the horizontal wheel shaft, the oil outlet is formed in the position notlower than the first bearing mounting section, and the oil outlet is communicated with the oil filling port; the first bearing is arranged on the first bearing mounting section in a sleeving manner;the oil deflector ring hermetically sleeves the horizontal wheel shaft and is higher than the first bearing. According to the horizontal wheel shaft assembly for the monorail train, a first oil outletis formed in the upper part of the first bearing mounting section on the outer circumferential face of the horizontal wheel shaft, and it can be guaranteed that an effective amount of lubricant is injected into the first bearing; meanwhile, the lower end face of the horizontal wheel shaft is provided with an oil injection port, the horizontal wheel does not need to be detached when the lubricantneeds to be injected, and operation is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a horizontal axle assembly for a monorail train and a monorail train with the horizontal axle assembly. Background technique [0002] A horizontal wheel for monorail trains is disclosed in the related art, which includes a wheel rim and tires fixed on its seat ring. The wheel rim includes a spoke, and the spoke is connected to the hub through bolts. The two ends of the hub are respectively encapsulated with a sealing seat and a basin by bolts. The outer end of the sealing seat is extended with a convex mouth, which is inserted into the inner ring groove of the sealing cover, and the upper and lower rolling bearings spaced by bushes are installed in the center hole of the hub, and one side of the rim seat faces outward. Extending to form a disc-shaped rim, on the rim of the disc-shaped rim, an auxiliary wheel parallel to the tire is fixed by bolts. The outer diameter of the ...

Problems solved by technology

[0003] However, due to the structure of the above-mentioned horizontal wheels for monorail trains, an oil injection hole of this structure is opened on the upper side of the horizontal wheel hub. Under normal circumstances, the horizontal wheels are wrapped by the carriage. Extremely difficult, the horizontal wheels had to be removed from the bogie to complete the oiling of the upper bearings if necessary
