Description
The utility model relates to a kind of mechanical transmission speed change gear, especially a kind of automatic speed governor that is used for automobile.
At present, the stepless speed adjusting gear that disposes on the automobile, its volume is big, complex structure, Component are many, coupling horsepower is big, cost is high, installation and maintenance are difficult, consumes energy is many, the conversion gear is frequent during use, has brought great inconvenience to the driver.
The defective that the purpose of this utility model exists at prior art and provide that a kind of volume is little, simple in structure, cost is low, coupling horsepower is little, start gentlely close, reduction of speed steadily, the automatic speed governor of energy saving, it can finish the process of block selecting gearshift automatically according to road surface situation, engine behavior.
The purpose of this utility model is achieved in that a kind of automatic speed governor, it comprises being meshing with each other by gear on the output shaft and the gear on the input shaft and constitutes, it is characterized in that gear side on the input shaft affixed overcoat, be slidingly matched with input shaft, be inlaid with the high strength permanent magnet in the overcoat, the overcoat inboard is provided with free wheel device, free wheel device hub wheel and input shaft are fixedly connected, be provided with needle roller in the free wheel device, be inlaid with in the outer hub of free wheel device with overcoat in the corresponding high strength permanent magnet of permanent magnet, for micro-gap is arranged, the N utmost point and the S utmost point attract each other between two permanent magnets, form to be magnetic coupling.Its working principle is: the moment of torsion that is transmitted by motor, pass on the output shaft of speed changer, pass on the input shaft by gear engagement, the overcoat conjuncted with gear, permanent magnet in the overcoat is integrated, another part is passed the moment of torsion of coming by transmission shaft, enter speed reducer by input shaft, with the free wheel device hub wheel that is contained on the axle, needle roller, outer hub, permanent magnet in the outer hub is combined into another body, know from experience to close and be magnetic coupling when two, when its input shaft torque passes on the output shaft, be to be finished by the attraction force that two permanent magnets produce mutually, the magnetic moment of torsion of generation has replaced the Maximum Torque on the automobile shift.Three followers of connecting are meshing with each other on three magnetic couplings of series connection (three gears that are equivalent to automobile) on the input shaft and output shaft, become three shift transmissions.The automobile shift speed ratio, a retaining speed ratio maximum, three retaining speed ratio minimums, and give the magnetic moment of torsion of putting on gear, and three retainings are maximum, and two retainings are less than three retainings, and therefore a retaining non-magnet does not have and gives the power of putting, and has only free wheel device.Automobile in the process of moving, the variation of its engine working conditions and road surface situation is passed to magnetic coupling by input shaft and output shaft respectively, and magnetic coupling gives the moment of torsion of certain numerical value and puts on it, as a reference point, the automatic speed governor retaining is sought retaining by high gear toward low gear, constantly seek the input shaft torque identical point identical and cooperate operation, finish the process of block selecting variable block automatically with output torque.
This model utility is simple in structure, volume is little, cost is low, little, the energy saving of coupling horsepower, is more suitable in all cars of assembling.
Below in conjunction with accompanying drawing in detail the utility model is described in detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A sectional view of Fig. 1.
Shown in Fig. 1-2, a kind of automatic speed governor, it comprises by the formation that is meshing with each other of the gear (3) on the gear (2) on the output shaft (1) and the input shaft (6), its input shaft (6) cog (3) side affixed overcoat (4), be slidingly matched with input shaft (6), be inlaid with high strength permanent magnet (5) in the overcoat (4), overcoat (4) inboard is provided with free wheel device (8), free wheel device hub wheel (7) is fixedly connected with input shaft (6), be provided with needle roller (10) in the free wheel device (8), be inlaid with in the outer hub of free wheel device (8) with overcoat in the corresponding high strength permanent magnet of permanent magnet (5) (9), two high strength permanent magnets (5,9) between for micro-gap is arranged, the N utmost point and the S utmost point attract each other, and form to be magnetic coupling.
Claims (2)
1, a kind of automatic speed governor, it comprises by the formation that is meshing with each other of the gear (3) on the gear (2) on the output shaft (1) and the input shaft (6), it is characterized in that: gear (3) side on the input shaft (6) affixed overcoat (4), be slidingly matched with input shaft (6), be inlaid with high strength permanent magnet (5) in the overcoat (4), overcoat (4) inboard is provided with free wheel device (8), free wheel device hub wheel (7) is fixedly connected with input shaft (6), be provided with needle roller (10) in the free wheel device (8), be inlaid with in the outer hub of free wheel device (8) with overcoat in the corresponding high strength permanent magnet of permanent magnet (5) (9), form and to be magnetic coupling.
2, automatic speed governor according to claim 1 is characterized in that: between the two high strength permanent magnets (5,9) for micro-gap is arranged.
