Description
Technical field
The present invention relates to a kind of rail vehicle technology, specifically, what relate to is a kind of electric actuation techniques and rail vehicle system to be combined a kind of electric track car that possesses high acceleration capacity of design-calculated.
Background technology
Along with the development of high ferro technology and city underground, track traffic is the production of affect people's, life more and more.Different according to design goal and main application, rail vehicle can be divided into special-purpose rail vehicle body and general train in the commercial production.The former comprises electric flat carriage, railway tool car etc., and they are based on machinery, hydraulic pressure, electric tramsmission form driving iron tyre in the I shape track more.The latter comprises inter-city train, subterranean railway, high ferro etc.Owing to contact for pure rigid body between rail wheel and the rail, the laterally offset meeting in the car body driving process is suppressed dramatically, so car body is stablized when running at high speed, and sideway movement is functional.
The characteristics of electronlmobil are with vehicular energy power to be provided, and power wheel goes.Owing to cancelled between its propulsion source and the drive wheel that traditional mechanical is connected directly by power wheel; This torque that makes control system only need regulate drive motor gets final product the direct controlled wheel propulsive effort; And the response performance of electrical motor wants much fast than machine driven system, so electronlmobil possesses good acceleration and deceleration ability.This characteristic is also for the exploitation High Performance, kinetic control system and electronlmobil are laid a good foundation cheaply.For example, U.S. Ford once produced the electronlmobil of speed per hour 335km/h, and its hundred kilometers acceleration only need 2.5 seconds.
Existing rail vehicle technology like the high ferro technology, can make car body quicken to run to the high-speed of 400km/h, but its accelerator is slow relatively, and acceleration distance needs thousands of rice.For under the track road environment some to working condition measurement under the production operation of having relatively high expectations time response or the special equipment limit acceleration; Need provide can be at the mobile platform that accelerates to big speed than short range; This mobile platform must possess high acceleration capacity, such as being implemented in 200 meters the distance from the static 100Km/h that gives it the gun.If adopt conventional rails car mobile platform technology, will certainly be not enough because of acceleration capacity, cause test tracks long, system cost is too high and be difficult to realize.Therefore, consider electric actuation techniques and rail vehicle system are combined, design a kind of electric track car that possesses high acceleration capacity.
Literature search through to prior art is found; Liu Jinbao etc. relate to a kind of improvement electric track truck system in patent of invention " electric track car " (number of patent application 200420091905.6), be made up of compartment, road wheel, spacing track adjusting wheel, DC motor, brush, brake gear, anticollision device and walking track, strip conductor.This rail vehicle has been realized the combination of electric actuation techniques and track traffic technology, but the car body acceleration capacity is not strong, and track needs special the laying, and spacing track adjusting wheel inconvenient installation is not suitable for as the high acceleration mobile platform under the extraordinary operating mode of mentioning in the preceding text.
Summary of the invention
The objective of the invention is to overcome the problem that existing scheme middle orbit car does not generally possess higher acceleration capacity; The high acceleration ability that possesses in conjunction with electronlmobil and the guide function of rail vehicle and suppress excursion capability; Design a kind of later-model high acceleration electric track car, be used as the stable mobile platform that possesses the high acceleration ability of special operation condition demand.Simultaneously this rail vehicle have back and forth go, compound type characteristics such as efficient height, features simple structure, compatible existing high ferro track.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is following:
High acceleration electric track car of the present invention comprises: vehicle body, guide frame, and drive axle and drive wheel are right, and track adjusting wheel is right, DC machine, energy system, vehicle control syetem.Said rail vehicle is the layout pattern of four-wheel traveling, four-wheel guiding, body structure left-right symmetric, front and back symmetry; Track adjusting wheel is to carrying out bridge joint through guide bridge wherein; And link to each other with guide frame, acting on the I shape rail of both sides, the front and back drive wheel is to being arranged on the drive axle; Act on the hardstand between the guide rail, bear vertical load and transmitting tractive power and the braking force of car body and give the road surface.The front and back track adjusting wheel is to being connected through guide frame with vehicle body, and DC machine, energy system and vehicle control syetem all are arranged on the vehicle body, and said energy system is vehicle-mounted super capacitor, and vehicle control syetem is used to control DC machine, energy system carries out work.
Said rail vehicle vehicle body mainly is used for supporting assembling structure on the whole vehicle, and all loads comprise that vehicle-mounted energy, motor etc. and car body deadweight all can be through linking to each other to come transmitted load with vehicle frame on the car.Rail vehicle is not provided with and turns to and suspension, track adjusting wheel and vehicle body before and after guide frame mainly is used for connecting.
Adopt moving sets to be connected between said guide frame and the vehicle body, variable rate spring is housed between connector, four groups of springs are chosen as identical stiffness characteristics.
The drive pattern that the power form of said rail vehicle adopts battery-driven car promptly utilizes vehicle power as propulsion source, and starter motor drives transmission system thus, and drive wheel is to being with body movement before and after driving.
Described super capacitor is placed in the vehicle body centering portions.
Said vehicle control syetem is handled the perception information of onboard sensor to tire speed, acceleration/accel in real time, and related command is sent to motor driver, and control bottom layer driving motor is with speed control, the car body control that realizes the high acceleration rail vehicle.
Compared with prior art, the present invention has following beneficial effect:
(1) characteristics that combine propulsion source, type of drive and the conventional rails wheel rail rigidity of electronlmobil to contact; Design-calculated is equipped with the rail vehicle of guiding mechanism; Simple in structure, scheme is clear, not only possesses the high acceleration capacity of battery-driven car but also can when high-speed cruising, keep side direction steady.
(2) the required road environment of high acceleration rail vehicle can directly utilize existing high ferro track or common railway environment, and does not need to lay again, and because acceleration capacity is outstanding, in short range, just can reach at a high speed, requires low to track length and particularity.Can be greatly as the mobile test platform that possesses high acceleration capacity.
