Abstract
The utility model discloses a control device for automobile electric retarder, comprising a control switch, a controller, a power and an electric retarder. The control switch is connected with the controller. The utility model is characterized in that the controller is composed of an impulse surge resource, a CPU, and power elements; each of the power element in the controller is connected with each electromagnetic loop of the electric retarder; and all the electromagnetic loops in the electric retarder are in a work status when the control switch outputs a shift signal. The utility model applies a CPU, thus no matter which shift of the manual switch in the control switch is used to work, all the electromagnetic loops in the electric retarder work; besides, the dutyfactor outputted by each electromagnetic loop under the same retarder shift is the same, which makes the force on the rotors are the same without distortion; and the utilization frequency of each electromagnetic loop group is the same without easy damage, which increase the use life of the electric retarder.
Description
[technical field]
The utility model belongs to the control field of automobile retarder, and what be specifically related to is a kind of control mechanism of automobile electromagnetic retarder.
[background technology]
At present, on the part automobile electromagnetic retarder is installed, automobile is in the process of travelling, when the vehicle lower long slope, for fear of make vehicle be in lasting acceleration mode because of dead weight of vehicle, electromagnetic retarder will be started working, when the low-grade location that uses electromagnetic retarder is not enough to slow effect, need retarder is run to maximum by shelves, slow power greater than tractive force after, the speed of a motor vehicle descends gradually, and when dropping to the suitable speed of a motor vehicle, chaufeur need stop to slow down.Than under the complicated situation, chaufeur must frequent starting or is closed retarder in vehicle condition, and this has caused the stress of chaufeur to a certain extent, tired easily, and in this slow process, the speed of a motor vehicle is in the state of speed change degree always, causes the uncomfortable sensation of driver and crew.Thereby the retarder of constant sped control function just arranged, under identical vehicle condition, chaufeur can drop to 50～30Km/h with the speed of a motor vehicle earlier, press the constant speed shelves then during a certain speed in this scope, vehicle will keep this speed at the uniform velocity to travel this moment, so both can alleviate the stress of chaufeur, reduce the incidence of traffic accident, also can make driver and crew feel that the speed of a motor vehicle is steady, ride comfort.The control mechanism of this electric retarder also is to be made of hand control switch, controller, power supply and electric retarder basically.At present, the mode of electromagnetic retarder has two kinds of relay control and electron steerings, the control mechanism of these two kinds of electric retarders exists following shortcoming: when retarder is not oepration at full load, the work of part magnet coil, it is stressed to cause whole internal rotor part cutting magnetic line to form current vortex, the part not place of cutting magnetic line does not stress, so just cause the discontinuity of rotor, make the rotor distortion that is distorted easily, when twisting into to a certain degree, during rotor rotation and concentrating flux plate rub, gently then burn out a bearing, influence retarder service life, heavy then can twist off transmission shaft, damage change speed gear box or back axle differential gear, influence the cruising of whole car, cause traffic accident in various degree.The control mechanism of this electric retarder, always having one group or two groups of coils to be under which kind of gear at retarder all is full-load operation, for the coil that the identical life-span is arranged, use will inevitably make coil sections damage in advance like this, has a strong impact on the service life of retarder.
[utility model content]
In view of the deficiency that electric retarder control mechanism of the prior art exists, the technical problems to be solved in the utility model provides the control mechanism that stressed evenly, not yielding, the electric retarder of a kind of rotor uses the high automobile electricity retarder of mission.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme to realize: a kind of control mechanism of automobile electricity retarder, include hand switch, controller, power supply and electric retarder, described hand switch is connected with controller, it is characterized in that described controller is made up of impulse hunting source, CPU and power component, each power component in the described controller and the corresponding connection of every group of magnet coil in the electric retarder, when described hand switch was exported gear signal, all magnet coils in the electric retarder were all in running order.
The utility model is under the control of CPU, and rotor is stressed evenly, and is not yielding, is difficult for causing burning out a bearing, and twists off transmission shaft, damages faults such as change speed gear box or back axle differential gear; And the frequency of utilization of magnet coil is identical, and is not fragile, in the service life of having improved electric retarder, reduced the incidence of traffic fault.
Stressed evenly for the rotor that can make electric retarder, in the service life of improving electric retarder control mechanism, the dutycycle of described retarder every group of magnet coil output under same gear is identical.
For electric retarder can be controlled by the signal of multiple channel transmission, with the input end of controller can be with Foot-controlled switch or/and the ABS control system input be connected.
For this control mechanism and other electronic control unit are coordinated, also described controller can be connected with automobile CAN-bus, make the more effect of its performance.
[description of drawings]
Further describe embodiment below more in conjunction with the accompanying drawings.
Fig. 1 is a logic diagram of the present utility model;
Fig. 2 is the output waveform figure of the utility model prior art controller;
Fig. 3 is the output waveform figure of the utility model controller.
[specific embodiment]
As shown in Figure 1, the control mechanism of this automobile electricity retarder, include master cock, controller, power supply and electric retarder, described master cock is connected with controller, described controller is made up of impulse hunting source, CPU and power component, each power component in the described controller and the corresponding connection of every group of magnet coil in the electric retarder; As shown in Figure 3, with the master cock is that hand switch is an example, hand switch generally all has fourth gear, the utility model can be used the different dutycycle in the electronic control unit of setting electric retarder controller, be the size that the method for fixed frequency modulated PWM is controlled every grade outgoing current, the master cock gear is low, and outgoing current is little, the gear height, outgoing current is big.Because under the same gear, CPU controls every group of magnet coil and works, and CPU makes the dutycycle of its control outgoing current identical, when therefore having realized retarder to each gear engaged, it is respectively organized magnet coil and works simultaneously, make the suffered electromagnetic force of rotor even, and it is also basic identical respectively to organize the load that electronic coil bears, thus the defective of having avoided inhomogeneous, the indivedual magnet coil of the suffered electromagnetic force of the rotor that control method produced of known technology to operate at full capacity for a long time all the time.In the utility model, also can control electric retarder, the signal output part of Foot-controlled switch is connected with the input end of controller for making Foot-controlled switch; The ABS system generally all is installed on automobile, when the ABS system in when work, the control mechanism of electric retarder should quit work, thereby the signal output part in the ABS system also is connected with the input end of controller, works as ABS
During system works, so that notification controller quits work.For this control mechanism and other electronic control unit are coordinated, make the more effect of its performance, and controller is connected with automobile CAN-bus, make controller carry out intercommunication, and more accurately other devices such as retarder or ABS system are controlled.
