The utility model is described with reference to the accompanying drawing and with reference to specific embodiment.

Fig. 1-Fig. 4 is combined to describe the P gear halting mechanism 100 of the utility model embodiment first.

As Figure 1-Figure 4, the P gear halting mechanism 100 of the utility model embodiment may include driving portion 1, driving section 2 With braking parts 3, driving portion 1 can drive braking parts 3 to move by driving section 2, so that gearbox 200 of the braking parts 3 to vehicle Output shaft of gear-box 202 brake.

As shown in Figure 1, driving portion 1 can have drive shaft 12, drive shaft 12 can be rotated around own axes, drive shaft 12 On can be arranged be fixed with driving gear 13, to drive gear 13 that can rotate together with drive shaft 12, driving section 2 be can wrap Ring gear 21 is included, ring gear 21 can be set in outside driving gear 13 and engage with 13 bias of driving gear.In other words, ring gear 21 central axis is not conllinear with the pivot center of driving gear 13, to drive gear 13 that can further drive ring gear 21 Rotation.

As shown in Fig. 2, the number of teeth of driving gear 13 can be less than the number of teeth of ring gear 21, so that gear 13 be driven to rotate band When dynamic ring gear 21 rotates, the revolving speed that ring gear 21 rotates is less than the revolving speed that driving gear 13 rotates, to pass through ring gear 21 With driving gear 13 bias engage, can be realized during driving portion 1 is by power transmission to driving section 2 reduction revolving speed with Increase torque, and then the torque that driving section 2 is moved in driving braking parts 3 is bigger, convenient for driving braking parts 3 to the gearbox of vehicle 200 output shaft of gear-box 202 is braked.

Halting mechanism 100 is kept off according to the P of the utility model embodiment, is nibbled by the bias of ring gear 21 and driving gear 13 It closes, the effect that reduction of speed increases square can be realized, increase the labyrinth of square for reduction of speed therefore without other setting, P keeps off halting mechanism 100 it is simple and compact and occupy interior space it is smaller, be more convenient for assembling.Meanwhile the bearing capacity of P gear halting mechanism 100 is big, is driven back Difference is small, and manufacturing cost is low.

In some optional embodiments of the utility model, as shown in Figure 1, P gear halting mechanism 100 can also include flower Keyboard 22, flower keyboard 22 can be relatively fixed with ring gear 21, such as flower keyboard 22 both can be directly fixed with ring gear 21, flower Keyboard 22 can also be fixed with structures such as 200 shells 201 of gearbox jointly with ring gear 21, and flower keyboard 22 can be with ring gear 21 pivot center is conllinear, so that ring gear 21 can drive 22 common rotation of flower keyboard.

As shown in Figure 1, flower keyboard 22 can be fixed with splined output shaft 23, splined output shaft away from the side of ring gear 21 23 can be located at the pivot center of flower keyboard 22, and splined output shaft 23 can drive along the pivot center of flower keyboard 22 to separate The direction of moving axis 12 extends, and splined output shaft 23 can be with 31 location fit of brake axle of braking parts 3, so that brake axle 31 can be with With 23 common rotation of splined output shaft.

After the rotation of drive shaft 12 drives driving gear 13 to rotate as a result, driving gear 13 is further driven to 21 turns of ring gear Dynamic, ring gear 21 is further driven to the rotation of flower keyboard 22, so that brake axle 31 can drive brake axle by splined output shaft 23 31 rotations.

Specifically, as shown in Fig. 2, (i.e. splined output shaft 23 deviates from along axial direction for the axial free end of splined output shaft 23 One end of drive shaft 12) it can be equipped with the holding tank 231 for being suitable for accommodating brake axle 31, the inner wall of holding tank 231 is equipped with spline, system At least part of moving axis 31 can protrude into holding tank 231, and then the part that brake axle 31 protrudes into holding tank 231 can lead to Spline and 23 location fit of splined output shaft are crossed, to realize the common rotation of brake axle 31 Yu splined output shaft 23.

Specifically, as shown in figures 1 and 3, the outer peripheral surface of splined output shaft 23 can be arranged with sealing ring 24, spline output Axis 23 can be from wearing to the shell 201 of gearbox 200 outside, and splined output shaft 23 can be in the position for wearing shell 201 Cooperated by sealing ring 24 and the sealing of shell 201.Thus, it is possible to prevent moisture outside shell 201 from splined output shaft 23 and shell The gap of body 201 flows into shell 201, guarantees working environment dry in shell 201.

More specifically, the outer peripheral surface of splined output shaft 23 can be coated with powder coating.As a result, in shell 201 and flower The installed position of key output shaft 23 can effectively reduce shell 201 when gearbox 200 works and splined output shaft 23 produces Raw noise, and enhance the wear-resisting property of splined output shaft 23, it improves service life.

Specifically, as shown in Figure 1, flower keyboard 22 can be connect with ring gear 21 away from the side of driving portion 1, and flower keyboard 22 can be structure as a whole with ring gear 21.Thus, it is possible to guarantee to fix stronger, guarantee between flower keyboard 22 and ring gear 21 Ring gear 21 drives braking parts 3 to brake output shaft of gear-box 202 effectively by power transmission to flower keyboard 22.

More specifically, as shown in Figure 1, drive shaft 12 can partially protrude into flower keyboard 22, and can be with outside drive shaft 12 It is arranged with first bearing 121, flower keyboard 22 can be set in outside first bearing 121.First bearing 121 can support drive as a result, Moving axis 12 guarantees drive shaft 12 around own axis.

In other specific embodiments, the outer peripheral surface of ring gear 21 and the outer peripheral surface of splined output shaft 23 can be common It is fixed with shell 201, so that shell 201 can be rotated together with outer peripheral surface and splined output shaft 23, and it is further ensured that internal tooth Circle 21 and splined output shaft 23 it is relatively fixed.

In some specific embodiments, as depicted in figs. 1 and 2, driving gear 13 can be with towards the side of flower keyboard 22 The retention bead 131 of retention bead 131 equipped with multiple cylinders, multiple cylinders can be between the circumferential direction of driving gear 13 Every arrangement, flower keyboard 22 can be equipped with the limit hole 221 of multiple ellipses, and retention bead 131 can wear limit hole one by one 221.When driving gear 13 that flower keyboard 22 is driven to rotate, increase square effect due to slowing down, the revolving speed of driving gear 13 is greater than spline The revolving speed of disk 22, at this time each retention bead 131 can the circumferential direction in corresponding limit hole 221 along limit hole 221 move.

In some specific embodiments, as shown in Figure 1, Figure 2 and Figure 4, driving portion 1 may include driving motor 11, drive The output shaft of dynamic motor 11 can form drive shaft 12, and braking parts 3 can also include brake pawl 32, and brake pawl 32 can be with Brake axle 31 connects.

As shown in Figure 1, Figure 2 and Figure 4, when personnel need to carry out P gear parking, driving motor 11 can be enabled to drive drive shaft 12 Rotation, drive shaft 12 are further driven to driving gear 13 and rotate, and driving gear 13 is further driven to the rotation of ring gear 21, to realize Slow down and increase square, ring gear 21 is further driven to the rotation of flower keyboard 22, and flower keyboard 22 then passes through the driving driving of splined output shaft 23 Axis 12 rotates, and drive shaft 12 is further driven to the movement of brake pawl 32, so that brake pawl 32 protrudes into the tooth socket of output gear 203 It is interior, wherein output gear 203 can be arranged outside the output shaft of gear-box 202 for being fixed on gearbox 200, thus brake pawl 32 Output gear 203 can be prevented to rotate, and then realize the locking to output shaft of gear-box 202.

More specifically, as shown in Figure 1, drive shaft 12 can be pierced by the both ends of driving motor 11, and drive shaft along axial direction 12 be pierced by driving motor 11 away from driving gear 13 side can be arranged with second bearing 122, second bearing 122 can prop up It supports on the other component in vehicle, so that second bearing 122 can support drive shaft 12, guarantees drive shaft 12 around own axes Rotation.
