Fig. 1 shows the structural representation of vehicle antilocking braking system.See Fig. 1, the brake motor of antiblock device mainly comprises: electrical motor 11, for generation of anti-lock driving source; Transmission gearbox 12, for being converted to the rotation of slow speed of revolution height moment of torsion by the rotation of high rpm low torque; And rotating shaft 13, for utilizing the rotation of high moment of torsion to pull brake cable, reduce or eliminate the braking force of the brake units existed on the wheel of locking situation.
Wherein, described electrical motor 11 comprises output shaft 111, its one end connects electrical motor 11, gear in other end connection for transmission case 12, the driving source for being produced by electrical motor 11 exports to transmission gearbox 12, and described transmission gearbox 12 comprises, multi-stage gear, wherein one-level gear 121, is connected with the output shaft 111 of electrical motor 11, and described multi-stage gear changes the moment of torsion of transmission by changing rotating speed.
Specifically, the working process of the vehicle antilocking braking system in the utility model embodiment can carry out in the following manner.
First, after electrical motor 11 receives the anti-lock control signal of vehicle microcontroller, entry into service, carry out high rpm low torque rotation clockwise or counterclockwise, output shaft 111 on electrical motor 11 also follows high speed rotating, because output shaft 111 is connected with the gear of in transmission gearbox 12 121, therefore, gear 121 also operates under the drive of output shaft 111, other gears engaged with this gear 121 also rotate thereupon, because the diameter dimension of multi-stage gear strengthens gradually, therefore gear rotational speed reduces gradually, moment of torsion strengthens gradually, to the last during one-level gear, rotating speed drops to minimum, moment of torsion becomes maximum, the power of slow speed of revolution height moment of torsion is transferred to rotating shaft 13 by its output shaft by afterbody gear, rotating shaft 13 pulls the brake cable of vehicle brake unit clockwise or counterclockwise with the turning effort of slow speed of revolution height moment of torsion, the braking force on the wheel of locking situation is there is with instantaneous reduction or elimination.
In the utility model embodiment, alternatively, transmission gearbox 12 comprises 3 grades of gears; The hand of rotation of electrical motor 11 and rotating shaft 13 is only example.Be appreciated that in other embodiments, transmission gearbox 12 also can be the driving device of other types; Electrical motor 11 and rotating shaft 13 can rotate along any direction respectively, as long as can produce the pulling force pulling brake cable, thus reduce or eliminate the braking force existed on the wheel of locking situation.
Fig. 2 shows the block diagram of output shaft and gear.Fig. 3 shows the lateral plan of gear.See Fig. 2, one-level gear 121 in transmission gearbox 12 and output shaft 111 connection for transmission of electrical motor 11, for ensureing reliable transmission, gear 121 hardness is larger, opposed gear 121, the hardness of output shaft 111 is less, see Fig. 2, the diameter of gear 121 between 40-50mm, preferably between 43-47mm.The outer wall of gear 121 has the tooth of multiple other gears meshing of confession, and alternatively, the number of teeth is 50-80, is preferably 66.Gear 121 also comprises a centre hole installed for output shaft 111, and multiple tooth root circular hole, and alternatively, the number of tooth root circular hole is 5-8, and be preferably 7, the angle between two tooth root circular holes is 50-70 degree, is preferably 60 degree.Alternatively, the diameter of centre hole is greater than the diameter of tooth root circular hole, and alternatively, the diameter of centre hole is between 7-15mm, and tooth root circle bore dia is between 5-12mm, and preferably, the diameter of centre hole is 10mm, and tooth root circle bore dia is 8.3mm.The center hole wall of gear 121 has the dentalation being parallel to described gear 121 center shaft, mounted thereto for output shaft 111.
Output shaft 111 due to electrical motor 11 will drive the gear 121 of transmission gearbox 12 to rotate, therefore output shaft 111 needs to fit closely in the centre hole of gear 121, in order to ensure reliable transmission, the bore dia of gear 121 is slightly less than the diameter of output shaft 111, the tight joint adopting the magnitude of interference large between gear 121 and output shaft 111, thus avoid between gear 121 and output shaft 111, there is relative motion when transmission.When mounted, special instrument can be used to be expressed in the centre hole of gear 121 by output shaft 111, or utilize the characteristic of expanding with heat and contract with cold, the centre hole of gear 121 be heated, takes advantage of borehole enlargement, be set to rapidly on output shaft 111.
Because gear 121 material is harder, and the material of output shaft 111 is softer, at gear 121 with the elastic conjunction of output shaft 111, a large amount of metal burrs is often extruded by gear sheet in output shaft 111 surface, because output shaft 111 needs repair and replacement, the metal burr extruded will affect subsequent installation.Therefore, the centre hole of gear 121 of the present utility model adopts chamfer design.
Fig. 4 is the gear center hole part A enlarged drawing of Fig. 3.See Fig. 3 and Fig. 4, the centre hole of gear 121 adopts chamfer design, and on the tooth of one end that the centre hole of gear 121 is pressed near output shaft 111, be provided with chamfering, the length direction angulation of chamfering and tooth, between 2-15 degree, is preferably 5-10 degree; Fig. 4 gives the example that chamfering is 5 degree.The length of chamfering between 1-4mm, can be preferably 1.5-3mm.Alternatively, one end be pressed into away from output shaft 111 of the centre hole tooth of gear 121, also can be provided with chamfering, the length direction angulation of this chamfering and tooth, between 5-60 degree, is preferably 20-45 degree; The length of this chamfering between 0.2-1mm, can be preferably 0.5mm.That is, the chamfering at the tooth two ends in gear 121 centre hole can be arranged to different angles, different length, and generally, the chamfering length of the tooth of one end that axial compression enters is slightly long, and angle reduces.Alternatively, the chamfering at the two ends of the tooth in gear 121 centre hole can be set to symmetrical low-angle chamfering, and the chamfer angle of the tooth of one end that the chamfer angle of the tooth of one end that namely centre hole of gear 121 is pressed into away from output shaft 111 is pressed near output shaft 111 with the centre hole of gear 121 with length is identical with length or close.
Have chamfering due to the tooth of gear 121 being pressed into the position of installing near output shaft 102, and the angle design of chamfering is low-angle, length is longer than traditional length, therefore, facilitates the press-in of output shaft in installation process; In addition, because the angle of chamfering is less, length is long, each tooth of gear 121 is not easily formed the sharp end of scraping output shaft 111, input shaft 111 has sufficient transitional region when being pressed into, therefore this structure effectively can alleviate the scraping to axle, reduces metal burr in large quantities or essentially eliminates metal burr.In addition, at output shaft 111 with the transmission process of gear 121, because the size of chamfering is less, moderate length, output shaft 111 and gear 121 after installation is complete, still can closely cooperate, the relative motion between axle and hole can not be caused, ensure that the normal operation of transmission.
For confirming the technique effect of the utility model embodiment chamfer mechanism further, test experiments is carried out to the chamfering of following several specification:
A: chamfer angle is 5 degree, length is 1.5mm;
B: chamfer angle is 5 degree, length is 3mm;
C: chamfer angle is 30 degree, length is 0.5mm.
By the aperture design of gear 121 for be slightly less than 10mm, the overall diameter of output shaft 111 is set to slightly be greater than 10mm, after output shaft 111 is pressed into said gear 121, gear 121 is taken turns between sheet and output shaft 111 and is not occurred skidding, can judge thus, the design of chamfering does not affect torsional strenght.In addition, after tested, there is not burr after crimping in A, B two kinds of chamfering modes.C chamfering mode, burr reduces, but still jagged.This shows, be 2-15 degree by the angle design of chamfering, chamfering length is set to 1-3mm, can effectively reduce or prevent output shaft 111 surface from being taken turns sheet by gear 121 and extrude a large amount of metal burrs.
According to another aspect of the present utility model, in order to the chamfering of mate gear 121, also output shaft 111 and the installation position of gear 121 can be designed to chamfering pattern.Fig. 5 is the front view of motor output shaft.Fig. 6 is the partial enlarged drawing at Fig. 5 output shaft chamfer site (B position).See Fig. 5, output shaft 111 be length between 40-50mm, the axle of main diameter between 8-11mm, preferred diameter is 10mm.Output shaft 111 to comprise in the middle part of the shaft head 1111 and axle that to be connected with miscellaneous part or to assemble 1112, install the axle body portion 1113 coordinated and the connecting portion 1114 be connected with electrical motor 11 with gear 121, described connecting portion 1114 is positioned at the bottom in described axle body portion 1113.
The diameter of described shaft head 1111 is less than other positions of output shaft 111, in the middle part of axle, the diameter of 1112 is only slightly less than the diameter in axle body portion 1113, composition graphs 2 and Fig. 5 can find out, connecting portion 1114 is that the edge machining away certain length symmetrically abreast from the two bottom sides in cylindrical axle body portion 1113 forms, alternatively, its cutting face is oblong, and length is 15-20mm, and width is 4-7mm.Alternatively, the diameter of shaft head 1111 between 4-7mm, in the middle part of axle 1112 and the diameter in axle body portion 1113 between 8-12mm.
See Fig. 5 and Fig. 6, in the middle part of axle, the diameter of 1112 is slightly less than the diameter in axle body portion 1113, in the middle part of axle 1112 with the connecting portion in axle body portion 1113, be provided with a chamfering corresponding with the chamfering of gear 121, alternatively, the angle of the chamfering on output shaft 111 is between 2-15 degree, and length is preferably 1.5-3mm.Can according to the material of the material of output shaft 111 and gear 121, or the size of the chamfering of gear 121, the chamfering of corresponding design output shaft 111, makes the chamfering of output shaft identical with angle or similar with the length of the chamfering of gear.Preferably, corresponding with 5 degree of chamferings of gear 121, the chamfering of output shaft 111 also can be 5 degree.
When output shaft 111 is assemblied on gear 121, this chamfering coordinates with the chamfering on gear 121, output shaft 111 is more easily pressed in gear 121, and cooperatively interact due to two chamferings, be pressed in the process of gear 121 at output shaft 111, output shaft 111 can not by the sharp parts scraping of the chamfering of gear 121, thus making in the middle part of the axle of output shaft 111 1112, to pass through gear 121 inner, axle body portion 1113 is made firmly to be arranged on gear 121 inner, solve output shaft 111 surface is extruded metal burr problem by gear 121 further, facilitate follow-up installation, also the service life of output shaft 111 is extended.
Due to gear 121 and output shaft 111 being all provided with chamfering, effective minimizing or avoid output shaft and scraped and cut out metal burr, but adopt elastic conjunction due to output shaft 111 and gear 121, antiblock device upon actuation, the assembling position of said two devices is often subject to greater impact, cause the wearing and tearing of gear 121 or output shaft 111, output shaft 111 material is softer, unavoidable meeting is cut by gear 121 and is cut out metal burr, in order to the problem effectively avoiding axle surface to retain the metal burr be extruded, according to another aspect of the present utility model, on output shaft 111 surface, a debris removal mechanism is set.Fig. 7 is debris removal structural scheme of mechanism on output shaft.See Fig. 7, debris removal mechanism in the utility model embodiment arranges a groove 1115 on output shaft 111, the axle body portion 1113 that the position of described groove 1115 is positioned at, and with axle in the middle part of 1112 distance certain lengths, the size of groove 1115 can according to output shaft 111 diameter, the factors such as the material of gear 121 and output shaft 121 are determined, alternatively, the degree of depth of described groove 1115 is 0.05-0.15mm, width is 0.5-2mm, preferably width is 0.7-1mm, when in the centre hole that output shaft 111 is squeezed into gear 121, the edge of one end that the output shaft 111 that groove 1115 is just in time positioned at gear is pressed into or this edge close, like this, output shaft 111 is taken turns by gear 121 position that burr that sheet extrudes can be pulled to groove 1115, burr can rupture and even come off in the position of groove 1115, thus from root removal of burrs.Alternatively, at groove 1115, magnetic material or the sticking colloid material of tool can also be set for inner or adjacent edges, the burr come off is held or clings, thus avoid the burr come off to fall into gear or other parts and affect the engagement of gear.
