Fig. 1 is a kind of a kind of schematic diagram of embodiment of braking system of electric car of the utility model；
Fig. 2 is a kind of a kind of schematic diagram of embodiment of electric vehicle brake device of the utility model；
Fig. 3 is the schematic diagram that a kind of electric vehicle brake device of the utility model removes shell.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings.
With reference to figure 1, which is a kind of a kind of schematic diagram of embodiment of braking system of electric car of the utility model, this is
System includes：Brake pedal 1, the displacement sensor 2 being connected with brake pedal 1, the entire car controller 3 being connected with displacement sensor 2,
And the brake 4 being connected with entire car controller 3.Furthermore it is also possible to including pedal sense analogue unit 5, pedal sense can be passed through
The comfort level of analogue unit adjustment driver's brake.
Brake 4 is provided with braking motor 41, wedge block 42, sliding groove 43, friction plate 44 and brake disc 45, braking motor
41 one end is connected with entire car controller 3, and the other end of braking motor 41 is connected by output shaft with wedge block 42, wedge block 42
It is arranged in sliding groove 43, wedge block 42 is in Rising Wedge along the direction of motion, and sliding groove 42 is in along the direction of motion of wedge block 42
Falling Wedge；One side end face of friction plate 44 is contacted with wedge block 42, and another side end face of friction plate 44 is in contact with brake disc.
Motor 41, can be driven by entire car controller, its output terminal is connected with axle sleeve 411, and axle sleeve is connected with push rod 412,
Its bottom bracket axle carries internal thread, and push rod carries external screw thread, one end of push rod and axle sleeve and is threadedly coupled, the other end of push rod
It is connected with wedge block.The setting quantity of motor can be set according to actual conditions, such as set 4, four motor difference
For driving four wedge blocks being attached thereto.
Wedge block 42, quantity and the setting quantity of motor match, when braking motor is four, wedge block is also four
It is a.Therefore wedge block can be in four direction to friction plate applying power.
Sliding groove 43, can be separately provided, be attached with friction plate, and sliding groove and friction plate set the knot of split at this time
Structure.Sliding groove can also be arranged on sliding panel 46 as a structure of sliding panel 46.So sliding panel and friction plate phase
Connect, so as to reduce friction of the wedge block to friction plate during active force is applied.
Brake disc 45, is connected with the tire of electric automobile.Friction plate 44 is respectively arranged at two endfaces of brake disc 45.
Sliding panel 46, in addition to it can set sliding groove, can also set multiple circular holes, can be set in circular hole and circle
The axis that hole coordinates, circular hole and axis are engaged and good supporting role are played to sliding panel.
Furthermore it is also possible to including supporting rack 47, which can fix on the shell.It can be set respectively on supporting rack 47
The placement location of friction plate and the Support Position of sliding panel are put, so can both make sliding panel and friction plate relatively close to can be into
The transmission of row power, and sliding panel and friction plate is supported well.
In addition, brake further includes shell, shell is fixed on the brake wheel, braking motor, friction plate, sliding panel and wedge shape
Block is all disposed within shell.In addition shell is the sliding groove phase one that can be arranged on the corresponding position of wedge block on sliding panel
The trough of cause, not only plays guiding role for wedge block, meanwhile, the power that the rotation of brake disc can also be produced by shell
Reaction so as to enhance the power of the generation of wedge block, and then finally enhances brake force on wedge block.
For brake in braking, braking motor is actuated for work under the action of complete machine controller, and braking motor passes through
Output shaft driving wedge block is slided along sliding groove, since wedge block along its direction of motion is in Rising Wedge, and sliding groove edge
The direction of motion of wedge block is in lower by wedge shape, therefore wedge block applies active force to sliding groove, since sliding groove is arranged on slip
On plate, sliding panel and friction plate joint, therefore the active force of wedge block is passed to by friction plate by sliding panel, friction plate to
Brake disc applies so as to produce brake force.When on the other hand, due to braking, during wedge block slides, brake disc also exists
Rotated with wheel, such rotation also passes through friction plate and passes to sliding panel, and sliding panel is subject to one to be transported with wedge block
Dynamic direction opposite effect power, acts on wedge block, then wedge block have received one and move the identical active force of trend,
So as to increase the power of wedge block generation, the effect of braking is further increased, while also reduces the requirement to motor, therefore
The said structure of the utility model embodiment, can use low power motor, it is possible to reach the effect of braking.
The above is the preferred embodiment of the utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the scope of protection of the utility model.
