Description

Technical Field

[0001] This invention belongs to the field of rail transit technology, specifically relating to a modular body-suspended shunting locomotive. Background Technology

[0002] Hydraulic transmission locomotives in industrial and mining enterprises, such as Figure 1 As shown. From front to back, the locomotive consists of the front engine room, power room, transmission-cooling room, driver's cab, and rear engine room. The locomotive is divided into various mechanical rooms by integral side walls and partition walls. The mechanical room, driver's cab, and underframe are welded together to form a whole. The power room contains a diesel engine, which drives the hydraulic transmission box via a universal joint on the upper part of the locomotive and then transmits the power to the bogies via a universal joint on the lower part of the locomotive.

[0003] Bogies of electric transmission locomotives in industrial and mining enterprises, such as Figure 2 As shown. The traction motor is located within the bogie frame. One end of it is connected to the axle via a rolling axle holder, and the other end is suspended from the crossbeam or rear beam of the frame via a boom and rubber pad. The driven gear on the wheelset is driven by the driving gear at the end of the motor shaft, causing the wheels to rotate.

[0004] The installation method of placing large components of hydraulic transmission locomotives within the side walls of the overall machinery compartment results in low efficiency in component assembly and disassembly. Powered by a diesel engine, the engine drives the hydraulic transmission box via an onboard universal joint, which then drives the wheelsets via an underboard universal joint and the bogie axle gearbox; the entire power transmission process is mechanical. In the context of "dual carbon" (carbon dioxide, carbon emissions, and carbon emissions), if clean energy sources such as batteries are used as the power source, the existing structure cannot achieve the locomotive's power transmission, requiring the use of traction motors to convert electrical energy into mechanical energy. However, the traction motors in existing electric transmission locomotives are located within the bogies; replacing the bogies would significantly increase costs.

[0005] Existing technology CN 202624213 U discloses a modular shunting locomotive body, comprising, from rear to front, a rear engine compartment, a driver's cab, an electrical compartment, a power compartment, a cooling compartment, and a front engine compartment arranged on the upper plane of the frame. The rear engine compartment, front engine compartment, and cooling compartment are integrally detachable modular structures, connected to the frame by tapered pin bolts. However, this structure does not solve the problem of how to easily convert a hydraulic transmission locomotive into an electric transmission locomotive or a hybrid locomotive.

[0006] Existing technology CN 204110033 U discloses a modular dual-power locomotive, the structure of which includes a chassis frame, on which are mounted an onboard equipment cabinet, a driver's cab, and a fuel tank; multiple underboard equipment cabinets are fixed to the lower surface of the chassis frame; a diesel generator set is mounted on the fuel tank; and a pantograph is mounted on the driver's cab. The problems solved are: the dual-power locomotive equipment adopts a modular independent cabinet structure, and the diesel generator set and fuel tank are integrated, making the equipment layout flexible, eliminating the need for fuel inlet and return pipes commonly used in internal combustion engine locomotives, reducing leakage points; wiring can be installed both on and under the vehicle, and the absence of a machine room reduces costs. However, this technology also does not solve the problem of how to easily convert the original hydraulic transmission locomotive into an electric transmission locomotive or a hybrid locomotive.

[0007] The prior art WO2020183492A1 discloses a hybrid and electric vehicle kit and conversion method that can convert a traditional fuel vehicle into a hybrid or pure electric vehicle. However, the method it uses involves applying the kit to specific parts of the internal combustion engine vehicle, which limits its application. It also does not provide a method for more convenient modification to the bogie of the original internal combustion engine vehicle.

[0008] Therefore, it is of great significance to provide a way to transform a diesel-powered hydraulic transmission locomotive into a locomotive powered by batteries or other clean energy sources by rationally arranging the bogies of the original diesel locomotive. Summary of the Invention

[0009] The technical problem this invention aims to solve is how to provide a locomotive with a novel structure. This invention, while retaining the original hydraulic transmission shunting locomotive underframe and bogies, upgrades the hydraulic transmission locomotive to an electric transmission locomotive through modularization and body-suspension technology, thereby providing a feasible guarantee for further configuration of multiple power sources. Specifically, this invention retains the original hydraulic transmission locomotive's undercarriage mechanical transmission components (including the undercarriage universal joints and bogies), and adds a drive unit assembly module to the original underframe structure. The drive unit assembly module and the undercarriage form a body-suspension structure, realizing the conversion of electrical energy into mechanical energy. Each module on the locomotive is an independent box-type unit, connected to the underframe by bolts.

[0010] The technical solution of the present invention includes the following:

[0015] Furthermore, the modular body-suspended shunting locomotive of the present invention also includes the following components: a brake chamber module, a driver's cab module, a converter module, and an auxiliary room module;

[0016] The brake chamber module, driver's cab module, converter module, and auxiliary chamber module are connected to the underframe and supported by the underframe.

[0017] The brake chamber module, driver's cab module, converter module, power source module, and auxiliary chamber module are all independent box-type units.

[0018] Furthermore, the power source module includes: a power battery module and a diesel engine power pack module that are independently configured.

[0019] Furthermore, the drive unit assembly module is connected to the converter module, and the converter module is connected to the power source module.

[0020] Furthermore, the base frame includes a mounting base located in the middle of the base frame, and the drive unit assembly module is fixed to the base frame via the mounting base.

[0021] Furthermore, the drive unit assembly module includes a traction motor, and the base frame also includes a traction motor ventilation duct module. The traction motor ventilation duct module is located in the middle of the base frame and connected to the base frame. The traction motor ventilation duct module includes a traction motor ventilation duct frame and a counterweight block, and the traction motor ventilation duct module is arranged around the traction motor.

[0022] The traction motor ventilation duct frame has a hollow cavity to accommodate airflow, and a counterweight is set at the edge of the traction motor ventilation frame.

[0023] Furthermore, the traction motor ventilation duct frame has an air inlet and an air outlet, with the air inlet located at the top of the traction motor ventilation duct frame and the air outlet facing the traction motor.

[0024] Furthermore, the power source module also includes a traction fan, which is connected to the air inlet on the traction motor ventilation duct frame to provide ventilation for the traction motor ventilation duct frame.

[0025] Furthermore, the converter module and the power source module are connected to the traction motor ventilation duct module, and the traction motor ventilation duct module provides support for the converter module and the power source module.

[0026] Furthermore, the converter module and the power source module are connected to the traction motor ventilation duct frame via threaded connectors.

[0027] By adopting the above technical solution, the present invention has at least the following beneficial effects:

[0028] (1) The present invention uses a body suspension structure. By setting a mounting seat in the middle of the underframe, the drive unit assembly is fixed and matched with the original hydraulic transmission locomotive bogie interface. On the basis of retaining the original hydraulic transmission locomotive underframe and bogie structure, the locomotive is upgraded from hydraulic transmission to electric transmission technology.

[0038] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0040] Unless otherwise defined, all scientific and technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art.

[0041] The beneficial effects of the present invention will be further illustrated below with reference to specific embodiments.

[0042] like Figure 3 As shown, the present invention provides a modular body-suspended shunting locomotive, comprising the following parts: a power source module 4, a base frame 15, a bogie 6, and an undercarriage universal joint 7;

[0043] Among them, the bogie 6 is connected to the underframe and supports the underframe 15. The undercarriage universal joint 7 is connected to the underframe 15 and also to the bogie 6. The power source module 4 is supported by the underframe 15.

[0044] The drive unit assembly module 8 is mounted on the chassis 15. The drive unit assembly module 8 passes through the chassis 15 and is connected to the undercarriage universal joint 7. At the same time, the drive unit assembly module 8 is connected to the power source module 4.

[0045] The drive unit assembly module 8 and the base frame 15 form a body suspension structure.

[0046] This invention retains the original hydraulic transmission shunting locomotive's undercarriage mechanical transmission components (including the undercarriage universal joint 7 and bogie 6), and adds a drive unit assembly module 8 to the original hydraulic transmission shunting locomotive structure. The drive unit assembly module 8 forms a body-suspended structure with the underframe, realizing the conversion of electrical energy into mechanical energy. The drive unit assembly module 8 includes an upper end and a lower end. The upper end is fixed to the underframe 15, and the underframe 15 includes a hollow structure that allows the lower end of the drive unit assembly 8 to pass through. The lower end of the drive unit assembly 8 is provided with an interface. When the lower end of the drive unit assembly 8 passes through the underframe 15, it is movably connected to the undercarriage universal joint 7. At the same time, the undercarriage universal joint 7 is connected to the bogie 6. This invention realizes the technical upgrade from hydraulic transmission locomotive to electric transmission locomotive through modular and body-suspended technology, thereby providing a feasibility guarantee for the further configuration of multiple power sources in the locomotive.

[0047] In some embodiments, based on the above embodiments, the bogie 6 of the present invention supports the underframe 15 while the undercarriage universal joint 7 does not support the underframe 15; preferably, the number of bogies 6 is 2.

[0048] In some embodiments, based on the above embodiments, the following components are also included: brake chamber module 1, driver's cab module 2, converter module 3, and auxiliary chamber module 5;

[0049] Among them, the brake chamber module 1, driver's cab module 2, converter module 3 and auxiliary chamber module 5 are connected to the base frame 15 and supported by the base frame 15.

[0050] Braking chamber module 1, driver's cab module 2, converter module 3, power source module 4, and auxiliary chamber module 5 are all independent box-type units.

[0051] By setting the brake chamber module 1, driver's cab module 2, converter module 3, power source module 4, and auxiliary chamber module 5 as independent box-type units, the present invention makes it easier to install and disassemble the various modules of the modular body suspension shunting locomotive, improves assembly efficiency, and thus greatly reduces maintenance and modification costs from the perspective of the whole vehicle.

[0052] In some embodiments, based on the above embodiments, the power source module 4 includes: a power battery module and a diesel engine power pack module that are independently configured with each other.

[0053] In this invention, the diesel engine power pack module includes a diesel engine.

[0054] In some embodiments, based on the above embodiments, such as Figure 4 As shown, the modular body-suspended shunting locomotive of the present invention further includes a mounting base 9, which is located in the middle of the underframe 15, and the drive unit assembly module 8 is fixed to the underframe 15 by the mounting base 9.

[0055] The present invention provides a mounting base 9 on the base frame 15 and adds a drive unit assembly module 8 to the original structure of the hydraulic transmission shunting locomotive without changing it, thereby reducing the cost of locomotive modification and enabling the original hydraulic transmission shunting locomotive to be directly converted into a hybrid locomotive.

After receiving the power, the drive unit assembly module 8 drives the locomotive through mechanical transmission.

[0058] In some embodiments, based on the above embodiments, the diesel engine power pack module and auxiliary chamber module 5 in the brake chamber module 1, driver's cab module 2, and power source module 4 are connected to the underframe 15, and the power battery module in the converter module 3 and power source module 4 are connected to the traction motor ventilation duct module.

[0059] In some embodiments, based on the above embodiments, the drive unit assembly module includes a traction motor, and the base frame 15 also includes a traction motor ventilation duct module, such as...

The traction motor ventilation duct module is arranged around the traction motor.

[0060] Preferably, the traction motor ventilation duct frame 14 includes a hollow cavity, which can be located on the opposite side of the traction motor, with openings on both sides;

[0061] Preferably, the traction motor ventilation duct frame 14 can be arranged on three sides of the traction motor, forming a "U" shape around the traction motor, with an opening on one side;

[0062] Preferably, when the traction motor ventilation duct frame 14 is arranged on three sides of the traction motor and surrounds the traction motor in a "U" shape, the counterweight 10 is arranged on the open side to achieve the balance of the locomotive axle load.

[0063] In some embodiments, based on the above embodiments, the drive unit assembly module 8 consists of two traction motors and a gearbox. The gearbox contains a set of helical gears. The traction motor drives one of the helical gears through its output shaft. After the power transmission is completed between the gears, the other helical gear outputs the power to the undercarriage universal joint 7, thereby driving the bogie 6 to move.

[0067] Preferably, the air outlets 12 are arranged diagonally, such as... Figure 5 As shown, the purpose is to enable faster ventilation so that the traction motor can cool down more quickly;

[0068] In this invention, since the two traction motors on the drive assembly 8 are the same, the air outlet 12 is on the opposite side. This adaptation and the interchangeability of the motors can reduce costs.

[0069] In some embodiments, based on the above embodiments, the power source module 4 further includes a traction fan, which is connected to the air inlet 13 on the traction motor ventilation duct frame 14 to provide ventilation for the traction motor ventilation duct frame 14.
