Abstract
The utility model discloses a brake system for a DC motor of an electric vehicle, comprising a motor, a controller matched with the motor, and a switch arranged on the brake handle, characterized by also comprising a relay, wherein the coil terminal of the relay is connected with a circuit connecting the controller with the switch of the brake handle, and the contact terminal of the relay is connected in the circuit of the controller and the motor. The brake system for a DC motor of an electric vehicle is improved based on the prior control circuit, employs conventional components, and is low in cost, simple in structure and convenient in mounting.
Description
Technical field
The utility model relates to the vehicle technology field, is specifically related to a kind of DC motor of electric car braking brake system.
Background technology
Traditional electric vehicle brake system is along with the wearing and tearing of brake block, and braking quality can significantly reduce, and forms a kind of potential safety hazard.For this kind situation, short circuit fast braking principle according to direct current machine, Chinese invention patent application prospectus CN1433137 discloses a kind of fast-braking method for DC motor and fast braking motor and brake system, this invention short circuit motor when cutting off dc motor power is realized braking, need to redesign the control circuit of electric motor car when being applied in the electric motor car, it is higher to implement cost, installs also inconvenient.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of DC motor of electric car braking brake system, and it is higher and inconvenient problem is installed to solve the prior art implementation cost.
The utility model is achieved through the following technical solutions:
A kind of DC motor of electric car braking brake system, comprise: motor, controller with electric drilling match, and be arranged on switch on the brake handle, be provided with relay, the coil terminals of described relay is connected in controller and the circuit that the brake handle switch is connected, and the contact terminal of described relay is connected in the circuit of controller and motor.
The further improvement of the utility model scheme is, the three-wire system power line of motor is connected to respectively the normally-closed contact two ends, the corresponding contact short circuit of opening.
The further improvement of the utility model scheme is that the normally-closed contact of relay is connected in the controller power circuit.
The further improvement of the utility model scheme is that the brake handle switch is normally open.
The advantage that the utility model is compared with existing technology is:
One, do change on the basis of the original control circuit of electric motor car, the accessory of employing is conventional device, and cost is very low;
Two, simple in structure, easy for installation.
Description of drawings
Fig. 1 is DC motor of electric car braking brake systematic schematic diagram.
Specific embodiment
As shown in Figure 1, a kind of DC motor of electric car braking brake system, comprise: motor, controller with electric drilling match, and be arranged on switch on the brake handle, be provided with relay, the coil terminals 1,2 of described relay is connected in controller and the circuit that the brake handle switch is connected, and the contact terminal 3 ~ 14 of described relay is connected in the circuit of controller and motor.
As shown in Figure 1, the three-wire system power line of motor is connected to respectively normally-closed contact 3-5,6-8,9-11 two ends, corresponding contact 4,7,10 3 short circuits opened.
As shown in Figure 1, the normally-closed contact 12-14 of relay is connected in the controller power circuit.
As shown in Figure 1, the brake handle switch is normally open.
When electric motor car normally travels, relay normally-closed contact 3-5, always conducting of 6-8,9-11; When needs stop, mediate brake handle, the conducting of brake handle switch closure, relay gets electronic work, become 3-4,6-7,9-10,12-13 conducting, and 4,7,10 3 be short circuit, realizes the motor short circuit, produces the opposing magnetic field, make the electric motor car fast braking, 12-13 opens circuit, and has cut off the power supply of controller, prevents that controller from burning out; The releasing of brake handle, the brake handle switch disconnects, relay electric-loss, each contact returns to normal, and electric motor car normally moves.
Claims (4)
