The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail:
As shown in Figure 1 and Figure 2, the automobile that a kind of rear track can modulation, comprises and being arranged in automobile back wheel wheel hub 1, for driving the external-rotor-type wheel hub motor 2 of trailing wheel.External-rotor-type wheel hub motor (external rotor permanent magnet wheel hub motor) comprises the outer rotor 21 being connected with rear wheel hub 1, is positioned at motor stator 22 and the stator installation shaft 23 of outer rotor.Outer rotor is connected with rear wheel hub by bolt.Stator installation shaft 23 is coaxial with automobile back wheel.Bumper 6 connecting vehicle frames 7 and stator installation shaft 23 of automobile back wheel.Bumper 6 comprises mount pad 63 on bumper, the shock strut 61 on bumper below mount pad and the damping spring 62 between mount pad and shock strut on bumper.Stator installation shaft 23 is perpendicular with shock strut 61.Shock strut 61 is connected with stator installation shaft 23 by fixed support 3.Shock strut 61 bottoms are provided with annular groove 9.Fixed support 3 is by being rotatably set in adapter sleeve 31 in annular groove and connecting stator installation shaft 23 bearing support 32 with adapter sleeve 31.
Between shock strut 61 and external-rotor-type wheel hub motor 2, be provided with wheelspan modulation mechanism.This wheelspan modulation mechanism comprise be arranged on the clutch bindiny mechanism 4 between adapter sleeve 31 and shock strut 61 and be arranged on shock strut 61 and outer rotor 21 between clutch distance adjustor 5.Clutch bindiny mechanism 4 comprises that four are circumferentially distributed on shock strut 61, along axially extended the first directive slide track 43 of shock strut, four be circumferentially distributed on adapter sleeve 31 lateral surfaces, with the first directive slide track the second directive slide track 45 one to one, first driver train that is set in the clutch cutting ferrule 44 on shock strut and can makes clutch cutting ferrule move along the first directive slide track that can move along the first directive slide track.The second directive slide track 45 extends axially setting along shock strut 61, and the second directive slide track is positioned at the first directive slide track below.Clutch cutting ferrule 44 medial surfaces are provided with four and the first directive slide track guide groove one to one.The first driver train comprises the first leading screw and nut mechanism 42 and is fixed on the first motor 41 on shock strut.The nut of the first leading screw and nut mechanism is arranged on clutch cutting ferrule.Screw mandrel one end of the first leading screw and nut mechanism is connected with the first outer rotor, and this screw mandrel parallels with shock strut axis.
A kind of rear track of the present invention can modulation automobile be by the automobile of application wheel hub motor technology is improved, by set up wheelspan modulation mechanism between shock strut and external-rotor-type wheel hub motor, the wheelspan of automobile back wheel can be regulated according to actual needs (increase or dwindle wheelspan); Its concrete use procedure is as follows:
In normal driving process, the second motor 53 drives the second leading screw and nut mechanism 54 to drive driven gear 52 to move along the 3rd directive slide track, and driven gear is separated with driving gear 51.Simultaneously, the first motor 41 drives the first leading screw and nut mechanism 42 to drive clutch cutting ferrule 44 to move down along the first directive slide track 43, makes the part in clutch cutting ferrule be enclosed within (clutch cutting ferrule 44 coordinates with first, second directive slide track 43,45 simultaneously) on adapter sleeve 31; Thereby make shock strut 61 and adapter sleeve 31 be connected as a single entity (preventing from rotating between shock strut 61 and adapter sleeve 31).
In the time of needs vehicles rear track: the first motor 41 drives the first leading screw and nut mechanism 42 to drive clutch cutting ferrule 44 up to move along the first directive slide track 43, make clutch cutting ferrule move to adapter sleeve 31 tops (clutch cutting ferrule separates with adapter sleeve).Then the second motor 53 drives the second leading screw and nut mechanism 54 to drive driven gear 52 to move along the 3rd directive slide track 55, and driven gear is engaged with driving gear 51.Follow, external-rotor-type wheel hub motor 2 is worked again, and outer rotor 21 drives driving gear 51 to rotate, thereby automobile back wheel is rotated around shock strut 61.When automobile back wheel rotates after 180 degree around shock strut 61, external-rotor-type wheel hub motor stops operating; Then, the first motor 41 drives the first leading screw and nut mechanism 42 to drive clutch cutting ferrule 44 to move down along the first directive slide track 43, and the part in clutch cutting ferrule is enclosed within on adapter sleeve 31; And then shock strut 61 and adapter sleeve 31 are connected as a single entity.
So far, realize the adjusting to automobile back wheel wheelspan, as shown in Figure 3, automobile back wheel turns to shock strut outside around shock strut 61, thereby increases automobile back wheel wheelspan L; As shown in Figure 4, automobile back wheel turns to shock strut inner side around shock strut 61, thereby dwindles automobile back wheel wheelspan L.
