Abstract

The utility model provides an arresting gear that rail vehicle is new, characterized by: arresting gear when braking, pass through increasing gear on the wheel pair with rail vehicle kinetic energy and drive the generator electricity generation, power generator shaft passes through the drum type tooth coupling with pinion shaft in this gear box and links to each other, and the electric energy that the generator sent is exported for flywheel battery through the converter that can carry out the AC and DC conversion, becomes kinetic energy into the electric energy and stores in flywheel battery, as rail vehicle with higher speed the time, direct current that converter through carrying out the AC and DC conversion was stored in with flywheel battery becomes the alternating current and comes actuating motor, and the motor passes through the reduction gear drive wheel to with higher speed, and the electric energy is transformed into vehicle kinetic energy among the flywheel battery, the generator uses as the motor when the drive, and at this moment, increasing gear has just become reduction gear.

Description

The brake unit that a kind of rail vehicle is new
Technical field
This utility model patent relates to the brake unit that a kind of rail vehicle is new.
Background technology
During rail vehicle braking, traditional method is to adopt mechanical friction brake unit or resistive braking device, is all the kinetic energy of vehicle is transformed into heat energy and dissipates, this brake unit dependable performance, it can be ensured that run safety;But add maintenance cost, not energy-conservation again.Especially running velocity is higher such as EMUs, or need to frequently brake and draw such as subway, light rail vehicle, not only the kinetic energy of vehicle dissipates in vain when braking, brakes itself be it is also proposed requirements at the higher level, such as thermostability, wearability and maintenance and convertibility.After adopting flying wheel battery, just the kinetic energy of vehicle can be become electrical power storage in flying wheel battery by electromotor during rail vehicle braking, when vehicle needs to accelerate, the electric energy being stored in flying wheel battery can be discharged accelerating to rotate by motor-driven wheel again, both energy-saving and environmental protection, safe and reliable again, it is often more important that brakes can non-maintaining and replacing.Traditional braking device has been far from suitable the brake request of future track vehicle, and adopting new brake unit is the development trend of future track vehicle.
Summary of the invention
In order to meet the brake request of future track vehicle, this utility model design provides a kind of features simple structure, reliable and energy-saving new brake device, and it fundamentally solves energy-saving and environmental protection, the maintenance of reliable and brakes and replacing problem.
By rail vehicle kinetic energy by taking turns upper step-up gear drive electrical generators generating when this utility model design solves the technical scheme is that braking of its technical problem, alternator shaft is connected by drum type gear coupling with the pinion shaft in this gear-box, the electric energy that electromotor sends exports to flying wheel battery through the converter that can carry out AC and DC conversion, kinetic energy becomes electrical power storage in flying wheel battery;When rail vehicle accelerates, the unidirectional current stored is become alternating current driving motor by carrying out the converter of AC and DC conversion in flying wheel battery, motor is by reduction gear box driving wheel to acceleration, and in flying wheel battery, electric energy is transformed into vehicle energy;Electromotor uses as motor when driving, and now, step-up gear has reformed into reduction gear box.
This utility model design provides the benefit that: 1, thoroughly solve energy recycling and environmental issue during rail vehicle braking;2, easy to use: this features simple structure, safe and reliable;3, maintenance and the replacing problem of rail vehicle braking system are thoroughly solved: utilize the charge-discharge performance of flying wheel battery, the brakes of future track vehicle will not be used resistive braking, the utilization rate of mechanical friction braking also will greatly reduce, and only just come into operation when running velocity is very low.
In order to alleviate vehicle unsprung weight, electromotor, the converter that can carry out AC and DC conversion and flying wheel battery both may be installed under vehicle body bottom frame, also may be installed on the bogie frame of vehicle, this utility model design also fundamentally solves the problem that motor vehicle braking system installing space is nervous.
Accompanying drawing explanation
Accompanying drawing is the structural representation of this utility model design.
In accompanying drawing: 1. it is right to take turns, 2. step-up gear, 3. drum type gear coupling, 4. electromotor, 5. can carry out the converter of AC and DC conversion, 6. flying wheel battery, 7. cable 1,8. cable 2.
Detailed description of the invention
As shown in drawings.
Detailed description of the invention is: the gear wheel of step-up gear 2 is arranged on the wheel axletree to 1 by interference fit, its pinion shaft is connected with the axle of electromotor 4 by drum type gear coupling 3, electromotor is connected with the converter 5 that can carry out AC and DC conversion by cable 2, and converter 5 is connected with flying wheel battery further through cable 1;When flying wheel battery discharges, electromotor uses as motor, and step-up gear becomes reduction gear box.

Claims (2)

1. the brake unit that a rail vehicle is new, it is characterized in that: during the braking of described brake unit, by rail vehicle kinetic energy by taking turns upper step-up gear drive electrical generators generating, alternator shaft is connected by drum type gear coupling with the pinion shaft in this gear-box, the electric energy that electromotor sends exports to flying wheel battery through the converter that can carry out AC and DC conversion, kinetic energy becomes electrical power storage in flying wheel battery;When rail vehicle accelerates, the unidirectional current stored is become alternating current driving motor by carrying out the converter of AC and DC conversion in flying wheel battery, motor is by reduction gear box driving wheel to acceleration, and in flying wheel battery, electric energy is transformed into vehicle energy;Electromotor uses as motor when driving, and now, step-up gear has reformed into reduction gear box.
