Abstract
An electric power-assisted braking system of a hybrid powered vehicle relates to the technical field of braking systems of hybrid powered vehicles. The electric power-assisted braking system of the hybrid powered vehicle comprises a drive axle connecting wheels on two sides of the vehicle and a driving motor mechanically connected with the drive axle, wherein a main motor controller is electrically connected to the driving motor, the main motor controller is electrically connected with an electric energy storing device. By adopting the electric power-assisted braking system of the hybrid powered vehicle provided by the utility model, the braking performance of the vehicle can be greatly improved, the temperature of hubs can be reduced, the tyre burst and brake overheating can be avoided, and the abrasion of the hardware of the vehicle braking system can be lessened, so that the running safety and stability of the vehicle are improved, the use cost of the vehicle is lowered, the fuel economy of the vehicle is improved, and good environment-friendly effect is achieved. As a current-vortex speed reducer is not employed any more, the weight and size of a machine body can be efficiently reduced, and the consumption of electrical energy can be lowered.
Description
Technical field
The utility model relates to hybrid vehicle brake system technical field.
Background technology
The vehicle braked system has generally comprised braking during standstill (parking brake) and service brake (brake pedal).For urban public traffic vehicles,, need frequent brake snub in travelling owing to often stop.Automobile must utilize brake system to keep certain speed of a motor vehicle when lower long slope.Yet, under above situation, only rely on the friction-type service brake can't satisfy brake request fully, at present generally on the basis of preceding two kinds of brake system, install various auxiliary braking systems additional, comprised exhaust auxiliary braking, current vortex retarder, liquid vortex flow retarder and engine braking apparatus etc.Increase auxiliary braking system and can not only guarantee under various operating modes and road conditions condition, and can also reduce wearing and tearing, the harm of avoiding driving a vehicle and bringing motor vehicle braking system hardware to effective control of vehicle speed.
In the hybrid vehicle brake system, except that traditional braking during standstill (parking brake) and service brake (brake pedal) device, equally also increased auxiliary braking system.Present hybrid power passenger car mainly adopts current vortex retarder.The groundwork of current vortex retarder is the purpose that reaches car retardation by the effect of the magnetic field between stator and the rotor.But use current vortex retarder to have a series of problems such as size is huge, body is heavy, consumed power, add and get on the car because the energy that braking consumes has accounted for very big ratio, and this part energy consumes with the form of drag friction generation heat usually, not only waste energy, also can cause brake overheating.
Summary of the invention
The purpose of this utility model is to solve the problem that prior art exists, a kind of generation that improves the vehicle braked performance, avoids brake overheating is provided, reduces wearing and tearing motor vehicle braking system hardware, to improve running safety and stationarity, reduce the vehicle operation cost, improve the fuel economy of automobile, and can effectively reduce the hybrid vehicle electric power auxiliary braking system of cabinet size and weight.
The technical scheme that its technical matters that solves the utility model adopts is as follows:
Hybrid vehicle electric power auxiliary braking system, comprise the drive axle that connects automobile both sides wheel, with the drive motor of drive axle by mechanical connection, by being electrically connected main electric machine controller, main electric machine controller is by being electrically connected apparatus for storing electrical energy on drive motor.
Adopt the utility model, vehicle is in deceleration or braking procedure, no longer drive wheels operation of drive motor, but because vehicle inertia, wheel can not shut down immediately, still continues to overtake, drive motor was driven by mechanical drive by wheel and rotated this moment, main electric machine controller sends power generation command after detecting travel condition of vehicle, and drive motor imposes reverse excitation under the control of main electric machine controller, and drive motor is converted to electrical generator work.The running state of electrical generator can produce resistance to the vehicle inertia operation, makes car retardation or braking.In the said process, reason owing to drive axle and drive motor mechanical connection, drive motor will be converted to electric energy by the mechanical energy that wheel operation is delivered to drive motor, and electric energy is delivered to apparatus for storing electrical energy after by main electric machine controller, and with electrical power storage in apparatus for storing electrical energy.
The beneficial effects of the utility model are, can greatly improve the vehicle braked performance, reduce the wheel hub temperature, avoid blowing out and the generation of brake overheating, minimizing to improve running safety and stationarity, reduces the vehicle operation cost to the wearing and tearing of motor vehicle braking system hardware, improve the fuel economy of automobile, have good environmental protection effect.Owing to no longer adopt current vortex retarder, can effectively reduce body weight and size, reduce power consumption.

Fig. 2 is the utility model system circuit diagram.
Among the figure, 1-drive axle, 2-drive motor, 3-master's electric machine controller, 4-apparatus for storing electrical energy, 5-wheel.
The specific embodiment
Further set forth content of the present utility model below in conjunction with Figure of description and specific embodiment.
Figure 1 shows that Series Hybrid-Power Vehicle electric power auxiliary braking system constructional drawing, the electric power auxiliary braking system is by drive axle 1, with the drive motor 2 of drive axle by mechanical connection, form by the apparatus for storing electrical energy 4 that is electrically connected by the main electric machine controller 3 that is electrically connected with main electric machine controller 3 with drive motor 2.Among Fig. 1, solid line is represented mechanical connection, and dotted line is represented to be electrically connected, and arrow is represented the energy Flow direction.Figure 2 shows that Series Hybrid-Power Vehicle electric power auxiliary braking system circuit diagram.
In car retardation or braking procedure, no longer drive wheels operation of drive motor 2, but reason owing to vehicle inertia, wheel can not shut down immediately, still continue to overtake, drive motor 2 was driven by mechanical drive by wheel and rotated this moment, sent power generation command behind the travel condition of vehicle that main electric machine controller 3 detects, drive motor 2 imposes reverse excitation under the control of main electric machine controller 3, drive motor 2 is converted to electrical generator work.The running state of electrical generator can produce resistance to the vehicle inertia operation, makes car retardation or braking.In the said process, owing to the reason of drive axle 1 with drive motor 2 mechanical connections, drive motor 2 will be converted to electric energy by the mechanical energy that wheel operation is delivered to drive motor 2, and electric energy is delivered to apparatus for storing electrical energy 4 after by main electric machine controller 3, and with electrical power storage in apparatus for storing electrical energy 4.
