Abstract
The utility model relates to a chassis, in particular to a chassis platform of an electric venue car. The chassis platform comprises a car frame, a hang, a brake, a front driving axle and a rear driving axle. The chassis platform is characterized in that: the chassis platform comprises an AC (alternating current) asynchronous dynamo, an AC variable-frequency controller, a lithium-ion power battery, a DC/DC (direct current) device and a vehicle-mounted high-frequency charger. Through optimizing and matching of the system, the comprehensive efficiency of the power system is obviously higher than that of the ordinary electric car, meanwhile, the control precision is high, and the start of the car is smooth without vibrating feel; furthermore, a carling adopting finite element optimization is the high-strength car frame with rectangular cross section, so the weight of the whole car is obviously lightened, and the driving range of the car is increased. The chassis platform of the electric venue car with novel structure and simpleness and reliability can meet using requirements of the venue car.
Description
Technical field
The utility model relates to a kind of car chassis, a kind of specifically electronic venue chassis platform.
Background technology
Electronic venue car is a kind of battery-driven car that is specifically designed to venue, station, harbour, and the obstacle of vehicle field of employment is more.Traditional electronic venue storage battery car is difficult to satisfy operating needs at aspects such as the stationarity of vehicle control and operation comforts, control accuracy is not high, vehicle start is not steady, often cause the frequent and obstacle collision of vehicle, make vehicle be destroyed the personal safety that also has influence on chaufeur and occupant simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is: at the defective of above prior art existence, a kind of electronic venue chassis platform is proposed, both guarantee requirements such as trafficability, dynamic property, and can effectively prevent car accident again, guaranteed vehicle and personal safety.
The technical scheme that the utility model solves above technical matters is:
Electronic venue chassis platform, comprise vehicle frame, suspension, drg, front driving axle and rear driving axle, it is characterized in that: also comprise AC induction motor, AC frequency conversion controller, lithium-ion-power cell and vehicle-mounted high frequency battery charger, lithium-ion-power cell is installed in the middle of AC frequency conversion controller and the vehicle-mounted high frequency battery charger, lithium-ion-power cell links to each other with AC induction motor by the AC frequency conversion controller, the electricity of lithium-ion-power cell is by the AC frequency conversion controller, become alternating current by direct current (DC), and control and drive motor motion.
The technical scheme that further limits as the utility model is:
The section of chassis side rail is a rectangle.Hang and be the Mai Fuxun independent suspension.AC induction motor and rear driving axle are integrated.Drg is a plate disc brake.AC frequency conversion controller and vehicle-mounted high frequency battery charger are installed in the both sides of seat respectively.
The utility model has the advantages that: the utility model adopts the AC frequency conversion power system, and through the optimization and the coupling of system, the power system combined efficiency is apparently higher than common storage battery car, and control accuracy height, vehicle start steadily do not have the vibration sense; Simultaneously, adopting the longeron of finite element optimization is the high strength vehicle frame of rectangular cross section formula, and complete vehicle weight is obviously reduced, and increases the continual mileage of vehicle.The utility model novel structure, simple and reliable, can satisfy venue car operating needs, have good economic benefit again, with venue car, tour bus and the electronic special vehicle of this kind chassis making, the various deformation vehicle be can derive, various venues, station and harbour are widely used in.

The specific embodiment
Embodiment one
The structure of present embodiment as depicted in figs. 1 and 2, be a kind of electronic venue chassis platform, comprise vehicle frame 1, AC induction motor 5, AC frequency conversion controller 6, lithium-ion-power cell 3, DC/DC device 7, vehicle-mounted high frequency battery charger 2, Mai Fuxun independent suspension 8, plate disc brake 9 and rear driving axle 4.Vehicle frame 1 is that longeron is the vehicle frame of rectangular cross section formula, AC induction motor 5 and rear driving axle 4 integral structures.The lithium-ion-power cell 3 of three-phase alternating current asynchronous motor supplied with variable frequency 5, the AC frequency conversion controller 6 based on vector control technology, lithium ion string and combination, BMS and vehicle-mounted high frequency battery charger 2 adopt vehicle-mounted mode to form.AC frequency conversion controller 6 and vehicle-mounted high frequency battery charger 2 are installed in the both sides of second series seat respectively, and the centre is a lithium-ion-power cell 3.The electricity of lithium-ion-power cell 3 becomes alternating current by AC frequency conversion controller 6 by direct current (DC), and controls and drive vehicle-mounted high frequency battery charger 2 motions.
The utility model adopts a kind of AC frequency conversion power system, and through the optimization and the coupling of system, the power system combined efficiency is apparently higher than common storage battery car, and control accuracy height, vehicle start steadily do not have the vibration sense; Simultaneously, adopt the high strength vehicle frame of finite element optimization, complete vehicle weight is obviously reduced, increase the continual mileage of vehicle.The utility model novel structure, simple and reliable, can satisfy venue car operating needs, have good economic benefit again, with venue car, tour bus and the electronic special vehicle of this kind chassis making, the various deformation vehicle be can derive, various venues, station and harbour are widely used in.
The utility model can also have other embodiment, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
