Abstract
The utility model proposes a kind of novel lower long slope retarder, comprising: electric machine controller, electric machine controller is electrically connected with slow functional switch, drive motor, Vehicular accumulator cell and power consumption device respectively.The utility model adopts the tubular electric heating element be arranged in engine radiator hydroecium, driving engine coolant circulation unit own is utilized to be distributed by heat, can be that thermal energy consumption is fallen by electric energy conversion after Vehicular accumulator cell full charge, thus continue to play buffer action in the mode of resistance braking, braking force can regulate automatically by the setting speed of a motor vehicle, thus saving space reduces costs again.
Description
Technical field
The utility model relates to motor braking technology, refers to a kind of lower long slope retarder especially.
Background technology
Hybrid electric vehicle is different from adopting the conventional vehicle of large-duty engine.Conventional vehicle does not allow extension neutral gear to slide when lower long slope be to utilize the resistance of driving engine to play brake action, thus prevent from causing danger because using drg to cause drg generation heat fade malfunctioning for a long time.And hybrid vehicle not only engine swept volume is little but also often not direct drive of wheel, so rely on driving engine downhill retardation to be not all right.
Current energy regeneration braking, because accumulator capacity is limited, after storage battery is full of electricity, regenerative braking will no longer work, and cause energy regeneration braking failure.
Utility model content
The utility model proposes a kind of novel lower long slope retarder, the technical matters that after the storage battery solved in existing energy regeneration technology is full of electricity, regenerative braking lost efficacy.
The technical solution of the utility model is achieved in that
Novel lower long slope retarder, comprising: electric machine controller, and electric machine controller is electrically connected with slow functional switch, drive motor, Vehicular accumulator cell and power consumption device respectively.
Preferably, power consumption device is be arranged on the tubular electric heating element in engine radiator hydroecium.
Preferably, also comprise brake pedal, brake pedal is provided with position transduser.
Preferably, also comprise lower long slope speed of a motor vehicle set point adjustment device, lower long slope speed of a motor vehicle set point adjustment device is connected with electric machine controller.
The utility model utilizes the kinetic energy of vehicle itself to drive electrical power generators to reach the object of braking, and power consumption device adopts the tubular electric heating element be arranged in engine radiator hydroecium, utilizes driving engine coolant circulation unit own to be distributed by heat.Therefore, can be that thermal energy consumption is fallen by electric energy conversion after Vehicular accumulator cell full charge, thus continue to play buffer action in the mode of resistance braking, braking force can regulate automatically by the setting speed of a motor vehicle, thus saving space reduces costs again, be also convenient to chaufeur manipulation guarantee driving safety.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only that principle of the present utility model is described, for those of ordinary skill in the art, under the prerequisite not paying creative work, the principle of work of this patent is had gained some understanding.
Fig. 1 is functional block diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the know-why in the utility model embodiment is clearly and completely described.Based on the know-why in the utility model, those of ordinary skill in the art are not making the every other embodiment based on this know-why obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the novel lower long slope retarder of one of the present utility model, comprise electric machine controller 13, electric machine controller 13 is electrically connected with slow functional switch 10, drive motor 14, Vehicular accumulator cell 9 and power consumption device 15 respectively, power consumption device 15 adopts the tubular electric heating element be arranged in engine radiator hydroecium, utilizes driving engine coolant circulation unit own to be distributed by heat.Therefore, can be that thermal energy consumption is fallen by electric energy conversion after Vehicular accumulator cell 9 full charge, thus continue to play retarded acting in the mode of resistance braking, braking force can regulate automatically by the setting speed of a motor vehicle, thus saving space reduces costs again.
Principle of work of the present utility model is:
First open slow functional switch 10, when chaufeur steps on brake pedal, control signal is input to electric machine controller 13 by the position transduser on brake pedal.After electric machine controller 13 receives this control signal, by its inner software loaded automatically by the former mode of operation to motor, change over the state (any electrical motor can be operated in Generator Status) of electrical motor as generator operation.Now electric machine controller 13 according to Vehicular accumulator cell 9 state of charge by software automatic decision, the electric energy feedback sent with the electrical motor of Generator Status work is charged (when storage battery quantity not sufficient) to Vehicular accumulator cell 9, or is defeated by power consumption device 15 and changes into thermal energy consumption and dissipate (when accumulator electric-quantity is sufficient).Compared with the true vehicle speed signal that electric machine controller 13 also transmits according to descending speed setting signal and the car speed sensor of input, regulate electrical motor electric energy generated number thus reach the size of regulating brake force, and then the object of the control descending speed of a motor vehicle.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
