Description
Technical field
The utility model belongs to EPB actuator technical field, relates to a kind of drag-line EPB actuator.
Background technique
Parking system in existing automobile is substantially all electronic parking system (EPB), but the coupling shaft in EPB actuator is due to structural design not ideal enoughization, causes: 1, coupling shaft amount of finish is large; 2, feed screw nut and coupling shaft need after assembling to fix with jackscrew, because coupling shaft adopts 45# steel to process, therefore need first on coupling shaft, to pass through hole processing jackscrew counterbore with little drill bit, but this counterbore are not easily processed.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of and reduce cost of goods manufactured, the drag-line EPB actuator of product stability of enhancing productivity, improve.
The purpose of this utility model has been come by following technical solution.This drag-line EPB actuator, be made up of lead screw assembly, feed screw nut, output gear, coupling shaft, pulling force sensor, motor, motor gear, duplicate gear and gear shaft, described lead screw assembly is fixed in feed screw nut, one end of feed screw nut and coupling shaft fixes, and the other end of coupling shaft is connected with pulling force sensor; The external diameter of described feed screw nut is fixed with output gear, and this output gear is meshed with the motor gear on motor by duplicate gear, is provided with gear shaft in duplicate gear; Described coupling shaft one end be connected with feed screw nut offers outside thread, and one end of described feed screw nut offers internal thread, and the feed screw nut of this female end offers jackscrew pilot hole.
As preferably, described coupling shaft and feed screw nut are fastened by outside thread and internal thread rotation, and are equipped with jackscrew by the jackscrew pilot hole on feed screw nut, and one end of jackscrew withstands on the outside thread of coupling shaft.
As preferably, the diameter that described feed screw nut opens female one end is greater than the diameter of feed screw nut's body.
The beneficial effects of the utility model are: 1, coupling shaft amount of finish reduces, and improves manufacturing efficiency; 2, on feed screw nut, process jackscrew pilot hole, compare and process jackscrew pilot hole on the coupling shaft adopting 45# steel to process, it is easier to process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is connecting axle structure schematic diagram of the present utility model.
Fig. 3 is feed screw nut's structural representation of the present utility model.
Label in accompanying drawing is respectively: 1, lead screw assembly; 2, feed screw nut; 3, output gear; 4, coupling shaft; 5, pulling force sensor; 6, motor; 7, motor gear; 8, duplicate gear; 9, gear shaft; 21, internal thread; 22, jackscrew pilot hole; 41, outside thread.
Embodiment
Below in conjunction with accompanying drawing, detailed introduction is done to the utility model: as shown in accompanying drawing 1,2,3, the utility model is made up of lead screw assembly 1, feed screw nut 2, output gear 3, coupling shaft 4, pulling force sensor 5, motor 6, motor gear 7 and duplicate gear 8, gear shaft 9, described lead screw assembly 1 is fixed in feed screw nut 2, feed screw nut 2 fixes with one end of coupling shaft 4, and the other end of coupling shaft 4 is connected with pulling force sensor 5; The external diameter of described feed screw nut 2 is fixed with output gear 3, and this output gear 3 is meshed with the motor gear 7 on motor 6 by duplicate gear 8, is provided with gear shaft 9 in duplicate gear 8; Described coupling shaft 4 one end be connected with feed screw nut 2 offers outside thread 41, and one end of described feed screw nut 2 offers internal thread 21, and the feed screw nut 2 of this female end offers jackscrew pilot hole 22.
Described coupling shaft 4 is tightened by outside thread 41 and internal thread 21 with feed screw nut 2, and is equipped with jackscrew by the jackscrew pilot hole 22 on feed screw nut 2, and one end of jackscrew withstands on the outside thread of coupling shaft 4; The diameter that described feed screw nut 2 has one end of internal thread 21 is greater than the diameter of feed screw nut's body.
Working principle of the present utility model is: when motor 6 receives control unit instruction, motor 6 works, through the two stage speed change of motor gear 7, duplicate gear 8 and output gear 3, motor 6 output torque is converted to the pulling force (note: coordinate with rotating prevention sleeve when feed screw nut 2 assembles, only can move at axial direction) of the axis of feed screw nut 2.Motor 6 inside has testing of electric motors to rotate the circuit of the number of turns, controller can carry out just controlling to Parking Brake according to rotating during upper task number of turns situation, compared by the different Ministry of worker by pulling force sensor 5 pairs of drag-line power simultaneously, and by carrying out drag-line force compensating to the control of motor 6.
The utility model is not limited to above-mentioned mode of execution; no matter do any change on its shape or material are formed; every employing structural design provided by the utility model, is all one distortion of the present utility model, all should thinks within the utility model protection domain.
