Embodiment 1

[0055] like Figure 1-6 As shown, the present invention discloses a sand-spraying lubrication system for EMUs. Since the braking and lubrication of EMUs are mainly performed on the head car of EMUs, the sand-spraying lubrication system disclosed in the present invention is often used in EMUs It should be noted that it can also be installed on other car bodies that require lubrication and braking.

[0056] The sanding lubrication system includes a sand box 1, a sanding pipe 5, a sandblasting nozzle, a lubricant supply device, a lubricating pipe 7 and an oil injection nozzle.

[0057] Wherein, the EMU comprises an underframe 2 and a bogie 3, the bogie 3 is rotatably mounted on the underframe 2, and a deflector 4 is arranged between the dynamic front end of the bogie 3 and the underframe 2, so as to improve the performance of the EMU. Dynamic performance, reducing the running resistance of the EMU. The sand box 1 is arranged between the bogie 3 and the dynamic front end of the ...

Embodiment 2

[0065] In the second embodiment provided by the present invention, the structure of the sanding and lubricating system in this embodiment is similar to that in the first embodiment, so the similarities will not be repeated, and only the differences will be introduced.

[0066] In this embodiment, the present invention specifically discloses that the lubricant supply device includes a drive pump, an oil-air mixing block and a distributor 8 .

[0067] A driven pump drives the lubricant into the oil-air mixing block. The distributor 8 is installed on the lubricating pipe 7, and through the lubricating pipe 7, it is connected with the outlet of the oil-air mixing block, and the two outlets of the distributor 8 are respectively connected with the oil nozzles on both sides through the lubricating pipe 7, so as to provide The wheels 6 on both sides of the group are sprayed with lubricant.

[0068] Specifically, the driving pump may be an air-operated plunger pump, and it should be n...

Embodiment 3

[0085] The present invention provides an EMU, comprising an undercarriage 2, a bogie 3 and the sand-sprinkling lubrication system in any one of the above-mentioned embodiments.

[0086] The bogie 3 is rotatably mounted on the underframe 2, and a deflector 4 is arranged between the dynamic front end of the bogie 3 and the underframe 2. The deflector 4 is provided with a plurality of flow guide grooves to improve the safety of the EMU. Dynamic performance, reducing the running resistance of the EMU.

Abstract

The invention discloses a d-series high-speed train and a sanding lubrication system. The sanding lubrication system is used in the d-series high-speed train, the sanding lubrication system comprisesa sand box, a sanding pipe, a sand blasting nozzle, a lubricant supply device, a lubrication pipe and an oil nozzle. When the d-series high-speed train needs to be braked, materials in the sand box are transferred to the sand blasting nozzle through the sanding pipe and scattered to a wheel through the sand blasting nozzle, and the adhesion coefficient between wheeltracks is improved. When the abrasion of a wheel rim needs to be reduced, the lubricant supply device transports a lubricant to the oil nozzle through the lubrication pipe, and the lubricant is sprayed to the wheel rim through the oil nozzle, the abrasion of the wheel rim is reduced, the number of times of grinding of the wheel is reduced, the maintenance cost is reduced, meanwhile, noise of the d-series high-speed train in curves and tunnels is reduced, and the risk of the wheel disengaging from tracks is reduced. In conclusion, according to the d-series high-speed train and the sanding lubrication system, the wheel abrasion of the d-series high-speed train is reduced, and the sliding probability of the d-series high-speed train during braking is reduced.

Description

technical field [0001] The invention relates to the technical field of railway transportation, in particular to an EMU and a sand spreading lubrication system thereof. Background technique [0002] As the EMU is used, the wear of the wheel rim will intensify, which will increase the number of wheel grinding and maintenance costs. danger. In addition, the EMU will inevitably bring about the problem of wheel slippage during the braking process. As the vehicle speed increases, the probability of wheel skidding increases. [0003] Therefore, how to reduce the wheel wear of the EMU and how to reduce the coasting probability of the EMU during braking is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In view of this, the first object of the present invention is to provide a sanding lubrication system, which can reduce the wheel wear of the EMU and reduce the sliding probability of the EMU during braking. [0005] The ...
