Abstract
The utility model relates to an electric motor car braking energy recovery unit with generator. The electric vehicle driving system comprises a driving shaft, a driving motor and a generator which are arranged on the driving shaft through a transmission and a differential mechanism, wherein the driving motor and the generator are both connected with a control system of the electric vehicle. The device is reliable in control, economical and practical, solves the problem of energy recovery of the electric vehicle for many years, namely, the kinetic energy generated by the speed of the electric vehicle during running is converted into electric energy in the process of speed reduction, and the electric energy is charged into the storage battery and effectively recovered, so that the energy utilization rate of the electric vehicle is improved, and the running mileage is increased.
Description
The utility model relates to the brake power recovering device of battery-driven car, particularly a kind of electric vehicle brake power recovering device that has electrical generator.
Battery-driven car be with storage battery as main energy sources, with the vehicle of electrical motor as major impetus, also have plenty of electrical motor and combustion engine provides hybrid power.The critical component of battery-driven car is a storage battery, and what of the energy that storage battery is stored have determined the continual mileage of battery-driven car.
At present, battery-driven car is because the factor on the battery technology generally is difficult to reach comparatively ideal continual mileage, if the kinetic energy during with car retardation is converted into electric energy, be recovered into storage battery, rather than friction braking slatterns, this is equivalent to increase the capacity of storage battery undoubtedly.
Therefore, battery-driven car research department all is devoted to solve braking energy recovery problem.Present existing solution is; By control system, when vehicle need slow down, transfer drive motor to electrical generator work, when being car retardation, drive electric power generation, electric energy is recovered into storage battery.But this scheme relates to technical matterss such as charging current control, current transformer control, with existing technology, can't solve reliably.
The kinetic energy that speed was produced when the utility model design-calculated purpose provided a kind of can reliably battery-driven car being travelled is converted into electric energy in moderating process, charge into storage battery, effectively reclaim, thereby improve the energy utilization rate of battery-driven car, the electric vehicle brake power recovering device that has electrical generator of increase continual mileage.
The electric vehicle brake power recovering device that the utility model design-calculated has an electrical generator comprises the axle drive shaft between two front driving wheels that are fixed on the chassis frame, diff and change-speed box are installed on axle drive shaft, described diff and change-speed box again with the support that is fixed on vehicle frame on drive motor link to each other with electrical generator, between two drive wheels and drive wheel and vehicle frame, also be provided with deflecting bar, the vehicle frame opposite side of corresponding drive axle is provided with flower wheel, and described drive motor, electrical generator all link to each other with the control system of battery-driven car.
Wherein, described electrical generator can be as required, selects varying number, different installation connecting portion and different connection modes.The connection mode of described electrical generator can be and directly is serially connected on the axle, also can be connected with the kinematic scheme of vehicle by belt-driving, gear transmission etc.
Describedly can arrange in the following order successively: electrical generator-drive motor-change-speed box and diff, or drive motor-change-speed box and diff-electrical generator with drive motor and electrical generator that change-speed box links to each other with diff.
The utility model design-calculated has the electric vehicle brake power recovering device of electrical generator, electrical generator and driving motor are independent respectively the installations, soon independently electrical generator is connected in the drive system of battery-driven car, in the battery-driven car driving process, when vehicle need quicken, electrical generator idle running is not generated electricity, when vehicle need slow down, the control system switch on made generator for electricity generation, and the electric energy that sends is recovered to storage battery, the electromagnetic torque of electrical generator plays brake action simultaneously.This mode is controlled reliably, economical and practical, solved a great problem of battery-driven car energy recovery for many years, the kinetic energy that speed was produced when soon battery-driven car travelled is converted into electric energy in moderating process, charge into storage battery, effectively reclaim, thus improve battery-driven car energy utilization rate, increase continual mileage.
Further describe the utility model below in conjunction with drawings and Examples.
Accompanying drawing 1 is a kind of structural representation that the electric vehicle brake power recovering device that has electrical generator of electrical generator is installed at the drive motor front end;
Accompanying drawing 2 is the structural representation of the electric vehicle brake power recovering device that has electrical generator of drive motor-change-speed box and diff-electrical generator for putting in order;
Wherein, label 1 is a drive wheel, and 2 is axle drive shaft, and 3 is drive motor, and 4 is change-speed box and diff, and 5 is electrical generator, 6 deflecting bars, and 7 is flower wheel, and 8 is vehicle frame, and 10 is support, and 11 is rack beam.
The electric vehicle brake power recovering device that has electrical generator as shown in Figure 1 comprises: be fixed on the axle drive shaft 2 between two front driving wheels 1 on the chassis frame 8, change-speed box and diff 4 are installed on axle drive shaft, described diff and change-speed box again with the support that is fixed on vehicle frame on drive motor 3 link to each other with electrical motor 5, between two drive wheels and drive wheel and vehicle frame, also be provided with deflecting bar 6, the vehicle frame opposite side of corresponding drive axle is provided with flower wheel 7, and described drive motor all links to each other with the control system of battery-driven car with electrical generator.
Wherein, described electrical generator can be selected different connection modes as required, as directly being serially connected on the axle, also can be connected with the kinematic scheme of vehicle by belt-driving, gear transmission etc.
Its working process is: when vehicle ', drive motor 3 work are travelled by change-speed box and diff 4, axle drive shaft 2, drive wheel 1 powered vehicle, and electrical generator 5 idle running are not at this moment worked; When vehicle need slow down, control system quit work drive motor 3.At this moment, the inertia kinetic energy of vehicle drags wheel 1 and 7, axle drive shaft 2, change-speed box and diff 4, drive motor 3 rotates, and also forces to drive bonded assembly electrical generator 5 and rotates; At this moment, control system makes electrical generator 5 energising work, begins generating, produces an electromagnetic torque opposite with direction of vehicle movement, acts on kinematic scheme, and vehicle is reduced speed now, and plays brake action, up to vehicle immobilization.
In said process, can regulate lock torque by the size of control system regulator generator working current.Simultaneously, electrical generator generated electricity can be recovered into storage battery, has so just finished effective recovery of braking energy.
