Description
Technical field
The utility model relates to electronic brake system (EPB) technical field, is specifically related to a kind of electric parking brake power assembly mechanism.
Background technique
The power assembly mechanism of electric parking brake generally comprises motor and driving mechanism.Wherein, driving mechanism primary responsibility reduces the output speed of motor and improves output torque simultaneously, and passes to brake calipers and realize parking function.Usual driving mechanism generally adopts the mode of V belt translation combination gear transmission or the mode of all-gear drive.In existing electronic brake system, in order to realize parking function, the velocity ratio of driving mechanism is needed to reach about 120.When using all-gear drive mode or gear to add belt wheel transmission mode, because velocity ratio is higher, a fairly large number of gear that often needs to be in transmission connection just can reach this velocity ratio, and therefore whole driving mechanism amount of parts is more, complex structure, manufacture cost are relatively high and the increase of transmission progression also can cause rotational noise to increase.
Model utility content
The defect that belt wheel transmission exists is added in order to overcome all-gear drive or gear, technical problem to be solved in the utility model is: under providing a kind of prerequisite reaching the required velocity ratio of braking, effectively reducing transmission progression, reducing the electric parking brake power assembly mechanism of manufacture cost and drive noise.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of electric parking brake power assembly mechanism, comprise motor, in described motor, motor shaft is set, described motor shaft one end is fixedly connected with or is wholely set motor gear, described motor gear is in transmission connection one-level gear, described one-level gear is installed or is wholely set worm screw, described worm and wheel is in transmission connection, and described worm gear is installed or is wholely set output block.
Electric parking brake power assembly mechanism described in the utility model specific works principle is as follows:
The power produced by motor is delivered to one-level gear by motor gear, the rotating speed of motor reduces by one-level gear, moment of torsion improves, one-level gear driven worm screw is rotated simultaneously, worm gear is delivered to again by worm screw, worm and worm gear can reduce rotating speed further, improve moment of torsion, finally by output block, moment of torsion is outputted to the break of brake calipers, realize parking function.
In electric parking brake power assembly mechanism described in the utility model, the reduction speed ratio of motor gear and one-level gear can be set to about 3, and the reduction speed ratio of worm gear and worm screw can be set to about 40.
As preferably, described output block is for exporting spline.
Further, described motor is arranged in casing.
The utility model compared with the existing technology has the following advantages and effect:
1, existing all-gear drive or gear are added belt wheel transmission and are modified into one-level gear and add Worm Wheel System by the utility model, because worm gear transmission ratio is large, compact structure, then effective minimizing transmission progression, decrease the amount of parts needed for transmission, and be conducive to the volume reducing whole power assembly mechanism, reduce the overall weight of power assembly mechanism.
2, electric parking brake power assembly mechanism described in the utility model, structure is simple, reasonable in design, and low cost of manufacture, operating noise are little.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological 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 embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of electric parking brake power assembly mechanism described in the utility model.
Label declaration: 1, motor; 2, motor gear; 3, motor shaft; 4, one-level gear; 5, worm screw; 6, worm gear; 7, output block.

Embodiment 1: as shown in Figure 1, a kind of electric parking brake power assembly mechanism, comprise motor 1, motor 1 is arranged in casing, arranges motor shaft 3 in described motor 1, motor shaft 3 one end is fixedly connected with motor gear 2 by crimping mode, motor gear 2 is in transmission connection one-level gear 4, one-level gear 4 is installed or is wholely set worm screw 5, and described worm screw 5 is in transmission connection with worm gear 6, described worm gear 6 is installed or is wholely set output block 7, described output block 7 is for exporting spline.
Embodiment 2: as shown in Figure 1, and the difference of a kind of electric parking brake power assembly mechanism and embodiment 1 is, described motor shaft 3 is wholely set with motor gear 2.Described being wholely set is integrated molding and forming.
The working procedure of embodiment 1, electric parking brake power assembly mechanism described in embodiment 2 is as follows:
Motor 1 provides power and is delivered to one-level gear 4 by motor gear 2, and one-level gear 4 drives worm screw 5 to rotate, and worm screw 5 is rotated and drives worm gear 6 to rotate, and worm gear 6 drives and exports spline 7 rotation and the break finally outputing power to brake calipers, realizes parking function.In whole power assembly mechanism, component needed for transmission are motor gear 2, one-level gear 4, worm screw 5, worm gear 6, output block 7, compared with adding belt wheel transmission with traditional all-gear drive or gear, further simplify transmission progression, decrease number of spare parts, reduce manufacture cost and operating noise, and whole power assembly organization volume obviously reduces, assembly quality obviously alleviates.
In addition, it should be noted that, the specific embodiment described in this specification, the shape, institute's title of being named etc. of its parts and components can be different.All equivalences of doing according to structure, feature and the principle described in the utility model inventional idea or simple change, be included in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
