Embodiment Construction

[0008] figure 1 and figure 2 Shown, the method that utilizes rubber wheel to reduce the noise that urban aerial rail train produces. The structure of the urban air rail train traffic is as follows: two legs of the door frame-shaped support frame 10 are arranged on both sides of the non-motorized vehicle lane, and two 'hook' shaped tracks 9 are housed on the crossbeam of the door frame shaped support frame 10, and the 'hook' shaped track 9 Copper strips are inlaid inside, and the 'hook' shaped track 9 is insulated from the crossbeam of the door frame-shaped support frame 10, and the positive and negative poles of the direct current are respectively connected to the copper strips installed in the two 'hook' shaped tracks 9; the 'hook' The upper half of the 'shaped track 9 is an insulating baffle. A permanent magnet synchronous motor 5 is installed on the front part of the train locomotive 1 bottom, and the driving gear 6 on the permanent magnet synchronous motor 5 axles is en...

Abstract

The invention discloses a method for reducing noise of an urban air rail train by utilizing rubber wheels. The structure of the air rail train is characterized in that two J-shaped rails are arrangedon a cross beam of a door frame-shaped support frame, copper strips are embedded in the two J-shaped rails, the J-shaped rails are insulated from the cross beam of the door frame-shaped support frame,positive and negative electrodes of a direct current are connected on the copper strips arranged in the two J-shaped rails, and the upper half parts of the J-shaped rails are insulating baffles; thefront section of the bottom of a train head is provided with a permanent magnet synchronous motor, and the permanent magnet synchronous motor drives the nylon fiber rubber wheels to rotate; rotating shafts of the two carbon fiber rubber wheels are connected together through an insulating coupler, and then are fixed at the rear section of the bottom of the train head through bearing seats, the twobearing seats are insulated from the bottom of the train head; and the two carbon fiber rubber wheels are pressed on the two J-shaped rails correspondingly. According to the method, the permanent magnet synchronous motor rotates to drive the two nylon fiber rubber wheels to rotate, so that the noise generated by the friction between the rubber wheels and the J-shaped rails is extremely small.

Description

Technical field: [0001] The invention relates to a method for reducing noise generated by urban aerial rail trains by using rubber wheels. Background technique: [0002] When the trolley of the existing three-dimensional garage walks, the noise generated by the friction between the wheels of the trolley and the track is very large. Therefore, residents in the community are not allowed to build the three-dimensional garage next to the residential buildings in the community. [0003] In order to solve the problem of rapid transportation, metros have been built in super-large cities, and light rails can only be built in larger cities. In order not to compete with cars for roads, the light rail is built in the air, that is, urban sky rail train traffic. In order to reduce the noise generated by the friction between the wheels of the urban sky rail train traffic and the rails, someone installed a glass sound insulation wall outside the city sky rail train traffic. Installing g...
