Abstract
The utility model provides a driving device for narrow rail and light rail vehicles in a city, which suits to be mounted inside narrow space and overcomes the shortcomings in the conventional driving devices of narrow rail and light rail vehicles that a motor has much possibility of ring fire and gears are easy to abrade. The driving device comprises an AC asynchronous traction motor, a drum-shaped gear type coupling and a closed one-stage gear reducer; the AC asynchronous traction motor is entirely hung on a framework of a vehicle; and the drum-shaped gear type coupling is arranged between an output shaft of the AC asynchronous traction motor and an input shaft of the closed one-stage gear reducer on a wheel set. The driving device arranged among the wheel sets of the narrow rail and light rail vehicles can solve driving problem of full hanging method in modernized light rail and narrow rail vehicles under the condition of small internal side distance of the wheels sets and limited arrangement space, avoid ring fire and greatly improve dynamic property of the vehicles.
Description
Technical field
The utility model relates to a kind of driving device, is specially a kind of driving device that is applicable to city narrow gauge light rail vehicle.
Background technology
Urban light rail system transport capacity is particularly useful in 50～1,000,000 people's medium-sized city and some large size cities that population is concentrated relatively, the little zone of residential density between subway and road public transport.But what many oldfashioneds ground light rail systems (for example Hong Kong) adopted is the circuit and the vehicle structure of narrow gauge, vehicle wheel has only 962mm length spacing to be used to install traction electric machine and driving device to a distance, and the driving device that upgrades or carry out the modernization restructuring light rail vehicle has been increased difficulty.Oldfashioned narrow gauge light rail vehicle adopts the power driven mode of DC traction motor and the transmission of straight-tooth exposed gear, and the shortcoming of this driving device is: (1) power resources are in DC traction motor, and weight per unit power is big, the easy ring fire of motor; (2) traction motor adopts axle hung type to install, and wheel is to bearing the weight of about 2/3 motor, and the dynamic performance of unsprung weight ambassador vehicle is poor; Impact caused the wheel vertical and lateral impact between circulation line irregularity and wheel and the rail, directly pass to traction motor and traction teeth wheel set, traction gear is fragile, the fault rate height; Traction motor seize position serious wear, leakage of oil; After the wearing and tearing of traction motor seize position, cause the gear pair line of centers to form angle, gear engagement states is poor, and the life-span is short.
Summary of the invention
For the shortcoming that exists in the driving device that overcomes old-fashioned narrow gauge light rail vehicle, and can install in narrow space, the utility model provides a kind of driving device that is applicable to city narrow gauge light rail vehicle.
The technical solution adopted in the utility model is: a kind of driving device that is applicable to city narrow gauge light rail vehicle, comprise alternating current asynchronous traction motor, drum-shaped tooth type shaft coupling and enclosed primary gear speed reducing box, the integral of alternating current asynchronous traction motor is on car structure, and drum-shaped tooth type shaft coupling is installed on alternating current asynchronous traction motor output shaft and takes turns between the last enclosed primary gear speed reducing box input shaft.
The alternating current asynchronous traction motor is installed on the car structure, belongs to the integral mounting means.The alternating current asynchronous traction motor produces prime power, drum-shaped tooth type shaft coupling is installed between alternating current asynchronous traction motor output shaft and the enclosed primary gear speed reducing box input shaft by taper shaft, as middle connecting device transferring power, it can adapt to axially, radially with the relative displacement of angle, the power of alternating current asynchronous traction motor output is delivered to enclosed primary gear speed reducing box on the axletree by drum-shaped tooth type shaft coupling, right through the deceleration rear drive sprocket, and then make the narrow gage vehicle operation.
The wheel that driving device described in the utility model is installed in the light rail narrow gage vehicle between, slow down and transferring power as middle connecting device, can solve under the situation little at distance between backs of wheel flanges, that arrangement space is nervous, the transmission problem of the integral mode of modernization light rail narrow gage vehicle, can be used for 70% new system low floor urban light rail vehicle, also can be used for the modernization restructuring of old-fashioned city narrow gauge light rail vehicle.In addition, this driving device has following characteristics: (1) power resources are in AC traction motor, and are in light weight, the problem that weight per unit power is little, do not exist the motor ring fire; (2) traction motor integral formula is installed, and wheel is not to bearing the weight of motor traction motor, and unsprung weight alleviates greatly, and the dynamic performance of vehicle is greatly improved; Impact caused the wheel vertical and lateral impact between circulation line irregularity and wheel and the rail, can directly not pass to the traction teeth wheel set, the service conditions of traction teeth wheel set is greatly improved, and fault rate reduces, and work life prolongs; Solved the problem of leakage of oil, environmental; Adopt the transmission of enclosed one-level speed-changing gear box, stable drive, noise is little, the life-span is long.In Hong Kong tramway train interchangeization transformation project of bearing by China's northern car group Yongji new speed per hour electrical equipment and electrical Co., Ltd, trial erection the driving device of this light rail narrow gage vehicle, obtained effect preferably.Compare with original driving device, whole installation weight has alleviated 250kg, and wheel has alleviated 400kg to unsprung weight; Stopped the leakage of oil problem, noise reduces by 20 decibels.

The specific embodiment
As shown in Figure 1, a kind of driving device that is applicable to city narrow gauge light rail vehicle described in the utility model, comprise alternating current asynchronous traction motor 1, drum-shaped tooth type shaft coupling 2 and enclosed primary gear speed reducing box 3,1 integral of alternating current asynchronous traction motor is on car structure 4, and drum-shaped tooth type shaft coupling 2 is installed on alternating current asynchronous traction motor 1 output shaft and wheel between enclosed primary gear speed reducing box 3 input shafts on 5.Alternating current asynchronous traction motor 1 produces the source propulsive effort, and integral is installed on the framework of vehicle, and wheel do not have direct contact to 5, and wheel does not bear motor weight and impact shock to 5.Drum-shaped tooth type shaft coupling 2 is used to connect motor and drop-gear box, and to drop-gear box, the relative displacement between absorption traction electric machine and the drop-gear box has horizontal, vertical and vertical deviation-correcting function in the little spatial dimension with the transmission of power of traction electric machine output.
In order further to reduce wheel 5 pressure and impact, enclosed primary gear speed reducing box 3 one ends are bearing in wheel on 5 with the rolling axle suspension bearing, and the other end is installed on (Fig. 3) on the car structure 4 by resilient hanger.Enclosed one-level angular gear drop-gear box 3 (Fig. 2), mainly form by major parts such as last lower box, large helical gear 7, bevel pinion axle 8, bearings 9, be used to reduce the rotating speed of traction electric machine, increase the moment of traction electric machine output, and final drive wheel makes vehicle operating to rotation.
