The transmission load is transmitted to the two sides through the universal joint shaft, and the universal joint shaft is also Arranged above the axle position. It is adapted to the minimum curve R125m, the wheel diameter is 1050mm, the axle weight is 23ton, the wheelbase is 2350mm, the maximum speed is 120km/h, and the anti-rolling device is not installed.

The Dongfanghong 4 diesel locomotive developed by Qishuyan Locomotive and Rolling Stock Works is a six-axle locomotive. It adopts C0 three-axle bogie. The hydraulic transmission is arranged on the vehicle body, from the hydraulic transmission to the axle bearing gearbox of the first axle. Both the 2-axis axle gearbox and the 3rd axle axle gearbox are equipped with universal joint shafts, and the universal joint shaft is arranged above the axle position. It is adapted to the minimum curve R125m, the wheel diameter is 1050mm, the axle weight is 23ton, the wheelbase is 1800mm+2100mm, the maximum speed is 140km/h, and the anti-rolling device is not installed.

The railway railcar bogie developed by Datong Locomotive Co., Ltd. is a B0 two-axle bogie. The output of the hydraulic transmission is transmitted to the axle gearbox of the second axle through the cardan shaft, and then transmitted to the second axle through the other universal joint shaft. A 1-axis axle gearbox in which the centerline of the cardan shaft is on the same plane as the axle centerline, and the frame beam is bent upwards so that the intermediate cardan shaft passes through the middle of the bogie, and the traction device is medium Heart pinning method. It is adapted to the minimum curve R125m, the wheel diameter is 915mm, the axle weight is 13ton, the wheelbase is 2400mm, the maximum speed is 130km/h, and the anti-rolling device is not installed. The second suspension uses four steel springs.

The CRH5A EMU produced by Changchun Bus Co., Ltd. of China adopts a two-axle bogie with universal joint shaft transmission. The bogie is characterized by the use of a bolster and a power shaft and a non-power on a bogie. axis. An axle gearbox is arranged on the power shaft, the hydraulic transmission device is arranged on the vehicle body behind the second axle, and a universal joint shaft is adopted between the hydraulic transmission device and the axle gearbox of the second axle, and the traction device is adopted. The center pin type, the frame uses a double beam steel pipe structure. It adapts to the minimum curve R100m, wheel diameter 890mm, axle weight 17ton, wheelbase 2700mm, maximum speed 250km/h.

The Puzhen Vehicle Company exports Tunisia's internal combustion EMU vehicles using a two-axle bogie. The hydraulic transmission is arranged on the vehicle body behind the second shaft, and the output rotation is transmitted to the second shaft of the second shaft through the cardan shaft. The axle gearbox is transmitted to the first-stage axle gearbox of the first shaft through another cardan shaft. The center line of the cardan shaft is on the same plane as the axle centerline. The frame adopts a double-beam steel pipe structure, and the universal joint shaft Under the beam steel pipe, the traction device adopts the "Z" type double tie rod structure, and the universal joint shaft passes through the traction device.

Adapt to the minimum curve R100m, wheel diameter 860mm, axle weight 16ton, wheelbase 2400mm, maximum speed 130km / h.

It is an unknown problem to design an internal combustion engine EMU that passes the 100-meter curve and has a speed of not less than 140 km/h.

As we all know, the 100-meter curve is the smallest curve in both EMUs and urban rail vehicles. It is extremely difficult to achieve the above indicators. Considering the calculations comprehensively, to meet the above-mentioned indicators, the designed EMU has an axle load of 19 tons and a wheelbase of 2300 mm, which is driven by a cardan shaft.

The above-mentioned German Type 118 and 119 diesel locomotive bogies, Beijing-type 3000 hp diesel locomotive bogies, and Dongfanghong 4 diesel locomotive bogies are not suitable for 140 km/h with axle load of 19 tons due to excessive wheel diameter and axle load. EMU. The axle of the railway track car developed by Datong Locomotive Co., Ltd. is too light, only 13 tons. The CRH5A EMU bogie produced by Changchun Bus Co., Ltd. has only one axle gearbox, the wheelbase is too long, and the axle weight is light. The axle load of the Tunisian internal combustion trains produced by Puzhen Vehicle Company is still light, the wheelbase is long, and the maximum speed is also slightly lower. The anti-rolling device is installed inside the bogie, which usually has disadvantages and is not conducive to overhaul. And maintenance.

A vehicle that uses a universal joint shaft can have a large shaft, shorten the wheelbase, and increase the speed of the vehicle. The technical difficulty is very large, and the bogie structure and the traction system and brake system matched with the bogie are required. Make a lot of improvements. such as,

The drawbar assembly 54 has one end connected to the traction seat 52 and the other end connected to the frame beam upper surface mount. The traction device has the advantages of simple structure and small space occupation; the disadvantage is that the traction point is relatively high, and it is difficult to adjust in the design, which has a direct influence on the axle weight transfer.

The center pin and the Z-shaped double traction rod structure traction device can reduce the height of the traction point to a certain extent, but the structure is mostly complicated for the welding member or the structure, and the production, installation and assembly size adjustment are difficult, and The structure cannot meet the smooth passage of the internal shaft of the internal combustion engine EMU drive.

2. At present, the transverse damper installed with the traction seat is only installed on one side. After the axle weight is increased, the damping increases and the amplitude requirement cannot be met.

3. The current frame beam structure, the wheelbase is difficult to shorten due to the length of the brake mount.

4. As the axle weight increases, it is necessary to increase the rigidity of the anti-rolling device.

The technical terms in this article are explained as follows:

1. In the prior art, there is an H-shaped box-shaped beam body structure, the beam body is hollow, and the plate which surrounds the beam body to form the upper and lower faces of the box type is called a cover plate, and the two sides of the side surface are The board is called a vertical board.
