Problems solved by technology

However, when there is a puncture, the strong impact force at the bottom will easily cause damage to the wheel cover itself, and break through the wheel cover and enter the passenger compartment; in the event of a fire, the flames and poisonous gas at the bottom of the vehicle will easily pass through the wheel cover and enter the passenger compartment.

Embodiment 1

[0043] Embodiment 1, the manufacture method of the fireproof wheel cover of rail transit vehicle, comprises the following steps:

[0044] ① Make a mold according to the size of the surface of the inner cavity of the wheel cover main body 1;

[0045] ②The two sandwich cores 112 are connected with the separator 111 to form a composite sandwich panel 11;

[0046] ③ spread the inner layer of glass fiber cloth, place the composite sandwich panel 11, and lay the outer layer of glass fiber cloth;

[0047] ④ Configure phenolic resin and curing agent in proportion, and inject the mixed resin and curing agent into the mold;

[0048] ⑤ Put the mold into the curing furnace or autoclave, pressurize and heat to cure the resin;

[0049] ⑥Take out the wheel cover main body 1 after cooling down.

Embodiment 2

[0050] Embodiment 2, the manufacture method of the fireproof wheel cover of rail transit vehicle, comprises the following steps:

[0051] (1) Production of wheel cover main body 1:

[0052] S1. Make a lower mold according to the surface of the inner cavity of the wheel house main body 1, and make a movable insert according to the size of the inspection port of the wheel house main body 1.

[0053] S2. Making the composite sandwich panel 11: use two sandwich cores 112 and partitions 111 to glue together to form a "core material-partition-core material" type, and then carve out the shape, chamfers, openings, etc. according to the typesetting blanking diagram feature.

[0054] S3. Laying: clean the surface of the mold, place and position the movable inserts; lay the inner layer of glass fiber cloth, place the composite sandwich panel 11, and lay the outer layer of glass fiber cloth;

[0055] S4. Resin infusion: configure phenolic resin and curing agent in proportion, and inject...

Abstract

The invention relates to a railway vehicle equipment compartment wheel cover, in particular to a refractory wheel cover of a rail transit vehicle and a manufacturing method thereof. The refractory wheel cover comprises a hollow wheel cover main body which is a fiber reinforced phenolic resin plate; a composite sandwich plate is put in the wheel cover main body, the composite sandwich plate is provided with a partition plate and two sandwich cores, and the partition plate is positioned between the two sandwich cores. The composite sandwich plate is put in the wheel cover main body made of phenolic resin, so that the wheel cover has the advantages of light weight, high strength, structural fire resistance, heat insulation and the like, can prevent strong impact force at the bottom from entering a passenger room in case of tire burst, can prevent damage, and can prevent flame and poison gas at the bottom of a vehicle from entering the passenger room in case of a fire.

Description

technical field [0001] The invention relates to a rail vehicle equipment compartment wheel cover, in particular to a fireproof wheel cover for a rail vehicle and a manufacturing method thereof. Background technique [0002] The straddle-mounted monorail vehicle is a type of rail transit vehicle. The vehicle uses rubber tires to straddle the beam-rail beam. In addition to the running wheels, guide wheels and stabilizing wheels are installed on both sides of the bogie. The two sides of the track beam ensure the safe and smooth operation of the vehicle along the track. Wheels such as running wheels, guide wheels and stabilizing wheels are key parts of the vehicle and need protection and regular maintenance. Therefore, wheel covers are installed at the bottom of the car body and above the wheels. The main function of the wheel housing is to isolate the bottom bogie area from the passenger compartment area. The wheel cover can also ensure that the splash produced by the tires d...
