Description

A suspension type monorail train driving device

technical field

The invention belongs to the technical field of rail transportation, in particular to the driving technology of suspended monorail transportation.

Background technique

With the rapid development of cities, the problem of traffic congestion is becoming more and more serious. The existing public transportation systems such as subways and buses cannot completely solve the current urban traffic congestion problem, and the urban space is not fully utilized. Existing public transportation has a serious impact on the environment. For example, the construction and operation of the subway will cause noise pollution and water pollution, and the construction period is long. At the same time, the public transportation system will produce a large amount of greenhouse gases, reducing the urban air quality.

The suspended monorail system can solve the above-mentioned shortcomings of the public transportation system. The so-called suspended monorail (Suspended Monorail) transportation system, the train is suspended in the box-shaped track beam with the opening below. The inside of the track beam is installed with the vehicle's running rails, guide rails, conductive rails and cables of other equipment systems. Compared with conventional railways, the biggest feature of suspended monorail trains is that the bogie structure is relatively special. In addition, it has the following advantages:

The track beam of the suspended monorail transportation system is elevated, and the line structure is narrow, which can make full use of urban space; rubber tires are used, so there is no noise pollution and no exhaust gas emission when driving; the rubber tires have good adhesion and are suitable for large slopes, Running on urban roads with small curve radius, etc.

Existing suspended monorail trains adopt the adhesive driving method, and there are many problems: first, the structure of the driving device is complex and inconvenient to overhaul. A large amount of manpower and material resources lead to high maintenance costs; second, due to the use of the rubber tire system, the rubber tire not only bears the supporting role, but also plays the role of driving and braking, resulting in a lot of rubber wear and tear. For the safety of transporting passengers, most The use of high-cost, high-quality tires results in high operating costs. Third, the gear transmission structure of the traditional motor has large vibration and noise during operation, and a large amount of heat is generated by wear and tear, and the transmission efficiency is reduced through the multi-stage transmission process.

Contents of the invention

The purpose of the present invention is to provide a suspension type monorail train driving device, which can effectively solve the problems in the above-mentioned background technology.

The purpose of the present invention is achieved through the following technical proposals. A non-contact driving structure of a bogie for a suspended monorail train is designed, including a bogie and a track beam. Both sides of the middle part of the bogie frame are equipped with mounting seats for linear motors. The axle with disc brake device is connected to the bogie frame through bearings. The two ends of the axle are equipped with running wheels. There are guide wheel mounting seats, safety wheels and guide wheels on both sides; the suspension device passes through the middle of the bogie frame to connect with the corbel, and an air spring is arranged between the corbel and the bogie frame, and the car body is hinged on the suspension The lower end of the device; the track beam is a box-shaped structure with an opening at the bottom, and the top is equipped with a positive conductive rail, and two negative conductive rails are respectively set on the inner side of the track beam, and the base of the induction plate is welded on the inner side of the track beam to correspond to the mounting seat of the linear motor s position.

Remove the adhesive driving device on the original bogie, including the traction motor, coupling, gear box, etc., change the original semi-shaft structure of the traveling wheel into a rotating shaft, and install on both sides of the frame under the air spring A linear motor, and induction plates are installed at corresponding heights on the inner side of the track beam.

The horizontal height of the side beam of the bogie frame is the same as that of the linear motor, and two guide wheels are respectively installed at both ends of the frame. guide rails used. At the end of the side beam of the bogie frame, there is a mounting bracket for the safety wheel of the traveling wheel, and there is a set of safety wheel devices for the traveling wheel on the left and right sides of the mounting bracket.

Compared with the prior art, the present invention has the advantages and effects that: the present invention adopts a non-adhesive driving device, and the traction and braking of the train are all realized through the interaction between the linear motor and the induction plate, which increases the climbing ability and alleviates the The burden of running wheels greatly reduces the wear of rubber tires, increases their service life, and reduces operation and maintenance costs.

The linear motors of general subways tend to have smaller gaps between the motor and the induction plate due to the wear and tear of the wheel rails. During maintenance, it is necessary to spend manpower to check and adjust the installation position of the motor in time. The linear motor of the present invention is installed vertically, and this vertical The installation method avoids the problems caused by the wear of the wheel and rail, which can simplify the maintenance process and improve the efficiency of the vehicle.

Due to the subtraction of driving devices such as traction motors and the absence of vibration and noise in gear transmission, this traffic system is truly noise-free. At the same time, the weight of the bogie is greatly reduced, the structure becomes lighter, and the passenger capacity can be appropriately increased.
