Detailed description of the invention
in conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
a kind of perambulator, comprises vehicle frame, wheel 1 and braking mechanism.The bottom of vehicle frame is located at rotationally by described wheel 1, and braking mechanism is installed between vehicle frame and wheel 1.
embodiment one
as shown in Figures 1 to 7, the braking mechanism of a kind of perambulator of the present invention, may be used in above-mentioned perambulator.Described braking mechanism has braking state and un-brake state, and described braking mechanism comprises brake disc 5, for the brake component 3 braked wheel 1 and acceleration device 2, brake component 3 is installed on vehicle frame, and brake component 3 can move by relative frame.Described acceleration device 2 is gear acceleration mechanism, and described acceleration device 2 has input end and mouth.Described acceleration device 2 comprises the first gear wheel shaft 6, second gear wheel shaft 7 and driving gear set 10.First gear wheel shaft 6 is installed in the input end of acceleration device 2, and the first gear wheel shaft 6 is fixedly connected with the wheel shaft 4 of wheel 1, and the first gear wheel shaft 6 rotates with wheel 1, and the first gear wheel shaft 6 has the first gear 8.Second gear wheel shaft 7 is installed in the mouth of acceleration device 2, and brake disc 5 is fixedly connected with the second gear wheel shaft 7, and brake disc 5 rotates with the second gear wheel shaft 7, the second gear wheel shaft 7 has the second gear 9.The axis of the first gear wheel shaft 6 parallels with the axis of the second gear wheel shaft 7.According to the designing requirement of the space size between wheel 1, vehicle frame and braking mechanism and transmitting ratio, driving gear set 10 can be made up of a pair pitch wheel or be made up of multipair pitch wheel.What select in the present embodiment is two pairs of pitch wheels, forms two-stage transmission gear shift.The gears meshing of the first gear 8 and driving gear set 10 input end, the gears meshing of the second gear 9 and driving gear set 10 mouth.First gear 8 number of teeth is more than the number of teeth of the second gear 9.Described brake disc 5 drives up through acceleration device 2 and to rotate with wheel 1, and because first gear 8 number of teeth is more than the number of teeth of the second gear 9, the rotating speed of brake disc 5 is higher than wheel 1 rotating speed.
in actual design, on the basis of designing requirement meeting transmitting ratio, above-mentioned driving gear set can also be compound planet gear or planet cycloid pin.Even can also remove driving gear set 10, directly the first gear 8 and the second gear 9 be engaged each other transmission.But it should be noted that, in above-mentioned several type of drive, first gear 8 number of teeth also must more than the number of teeth of the second gear 9, the rotating speed of this guarantee brake disc 5 is higher than the rotating speed of wheel 1.
described brake component 3 is for offering the slipper of latch 11, and described brake disc 5 is toothed disc.When described braking mechanism is in braking state, clamping teeth wheel disc between the teeth groove that the latch 11 on slipper is fastened on toothed disc.When described braking mechanism is in un-brake state, the latch 11 on described slipper departs from the teeth groove of toothed disc.
apply braking force by brake component 3 pairs of brake discs 5 in the present embodiment one and realize brake function, realized the acceleration of brake disc 5 by gear drive, gear drive can realize gear, compact conformation in less space.Because the number of teeth of the first gear 8 makes the rotating speed of brake disc 5 higher than the rotating speed of wheel 1 more than the number of teeth of the second gear 9, this also makes brake disc 5 under the brake action of brake component 3, rotates the braking that less angle can realize wheel, brakes sensitive.And according to mechanics principle and gear-driven characteristic, only need apply less moment to brake component 3 just can in the moment of the larger braking of wheel 1 place acquisition in order to clamp brake disc 5, the braking mechanism of perambulator is braked laborsaving convenience.
meanwhile, the brake mode of brake component 3 and brake disc 5 is fastened by latch 11 to realize between the teeth groove of brake disc 5, and latch 11 without relative displacement, makes the braking mechanism of the perambulator described in the present embodiment brake sensitiveer between the teeth groove of brake disc 5.
