The engine unit 10 generates a driving force through explosion of the fuel, and the input shaft unit 20 transmits the driving force of the engine unit 10.

The clutch unit 30 is mounted on the input shaft 20 and selectively transmits the driving force of the input shaft 20. When the driving force of the engine section 10 is transmitted to the input shaft section 20 by the clutch section 30, the vehicle can be moved by the rotational force of the input shaft section 20. In addition, if the driving force of the engine section 10 is not transmitted to the input shaft section 20 by the clutch section 30, the vehicle can be kept stationary even if the engine section 10 is driven.

The one-way clutch portion 40 is mounted on the input shaft portion 20 and rotates in conjunction with the input shaft portion 20. The one-way clutch portion 40 allows only one-way rotation. For example, the one-way clutch unit 40 may be rotated only in the direction in which the input shaft 20 is rotated by adjusting the rotation of the inner and outer rings. At this time, the inner ring of the one-way clutch portion 40 is rotated in conjunction with the input shaft portion 20, and the rotation in the direction opposite to the input shaft portion 20 can be restricted. The outer ring of the one-way clutch portion 40 can be kept fixed to the fixture.

The transmission gear unit 50 is equipped with a synchromesh unit 60 selectively connected to the one-way clutch unit 40. The transmission gear unit 50 can shift the gear ratio through a plurality of gears.

Therefore, when the one-way clutch unit 40 and the synchromesh unit 60 are engaged with each other, the one-way clutch unit 40 is allowed to rotate only in one direction, thereby preventing the vehicle from being skidded in the ramp.

FIG. 2 is a schematic view of a front wheel type and a rear wheel type in a shift device for preventing sloping of shafts according to an embodiment of the present invention, and FIG. 3 is a schematic view showing a dual clutch type in a shift device for preventing sloping of shafts according to an embodiment of the present invention.

In addition, the transmission 1 for preventing slope skidding according to the embodiment of the present invention can be applied to a dual clutch type transmission (see Figs. 3A and 3B).

In a general dual clutch type transmission, a shift is performed with reference to two input shafts 20, and a one-way clutch portion 40 is applied to each of the input shafts 20, so that it is possible to prevent the vehicle from being pushed up at all of the shift shafts 3A). The one-way clutch unit 40 can be applied to only one input shaft 20 of the two input shafts 20 when it is desired to implement the anti-skid function only in the lower stage or the rear suspension in charge of the oscillation of the vehicle.

On the other hand, in the dual clutch type transmission, two input shafts 20 at the lower end can perform power transmission for multi-shafts (see Fig. 3B). In other words, the two input shafts 20 transmit power through the first input shaft and the second input shaft through the outer input shaft. As a result, the one-way clutch portion 40 can be applied to the outer input shaft to prevent the vehicle from being sloped.

FIG. 4 is a view schematically showing a state in which a transmission rod is included in a transmission for preventing sloping of shafts according to an embodiment of the present invention. FIG. Referring to FIG. 4, the transmission 1 for preventing slope skidding according to an embodiment of the present invention may further include a transmission rod portion 70.

Various shift speeds can be achieved through the operation of the transmission rod portion 70. [ When the transmission gear unit 50 is brought into the neutral state by the operation of the transmission rod unit 70, the gears of the synchro mesh unit 60 and the one-way clutch unit 40 are not meshed. However, when the transmission gear unit 50 forms a speed change stage for forward or backward movement of the vehicle by the operation of the speed change rod unit 70, the gear meshing pressure between the synchromesh unit 60 and the one-way clutch unit 40 is made . This makes it possible to prevent the vehicle from being thrown in the ramp.

5 is a view schematically showing a state in which a one-way clutch unit and a synchromesh unit are engaged when a selection control unit is in an ON state in a shift device for preventing sloping of shafts according to an embodiment of the present invention. Way clutch unit and the synchromesh unit are not meshed when the selection control unit is in the OFF state in the transmission apparatus for preventing sloping of sloping according to the example. 4 to 6, the transmission 1 for preventing sloping of shafts according to an embodiment of the present invention further includes a selection control unit 81, a selection switch unit 82, and a selection control unit 83 can do.

The selection adjusting portion 81 is mounted on the one-way clutch portion 40, and the length thereof is variable. For example, the selection control unit 80 can be adjusted in the direction of the synchro mesh unit 60 by driving the servomotor.

 The selection switch unit 82 selects the length of the selection control unit 81. For example, the selection switch unit 82 may be formed at a position in which the driver can operate the vehicle. The driver can select the anti-jamming ON state or the anti-jamming OFF state by operating the selection switch unit 82. [

The selection control unit 83 controls the selection control unit 81 in accordance with the signal from the selection switch unit 82 to guide the one way clutch unit 40 and the synchromesh unit 60 to be engaged or disengaged.

That is, the selection control section 81 is mounted on the one-way clutch section 40 and the synchromesh part 60 provided on the transmission gear section 50 includes a pair of synchro-gear parts 61, 61), which are arranged in parallel to each other. When the driver operates the speed change rod portion 70 to form the speed change stage in the transmission portion 50, the synchro-gear portion 61 is moved so as to engage with the one-way clutch portion 40. [ At this time, when the selection regulating portion 81 is projected toward the synchro mesh portion 60, the synchroscopic elastic portion 62 is contracted and the meshing between the synchro-gear portion 61 and the one-way clutch portion 40 is not performed.

The operation of the ramp anti-skid control device according to an embodiment of the present invention will now be described.

That is, when the driver keeps the selection switch portion 82 in the ON state in order to prevent the vehicle from being pushed rearward in the ramp, the selection control portion 83, which is attached to the one-way clutch portion 40, 81) (see Fig. 5).

When the speed change stage is implemented by the operation of the speed change rod section 70 in a state in which the selection control section 81 does not protrude in the direction of the synchro mesh section 60, the synchro mesh section 60 moves in the direction of the one- So that it is possible to prevent the vehicle from being skidded on the ramp.

On the other hand, if the selection switch unit 82 is kept in the off state in order to prevent the driver from pushing the vehicle at his or her driving ability in the ramp, the selection control unit 83 controls the selection The length of the adjustment portion 81 is maintained in the direction of the synchromesh 60 (see Fig. 6).

When the speed change stage is implemented by the operation of the speed change rod portion 70 in the state where the selection adjusting portion 81 protrudes toward the synchromesh portion 60, the synchro mesh portion 60 moves in the direction of the one-way clutch portion 40 And is not engaged with the one-way clutch portion 40 by the selection adjusting portion 81 even if it is moved. This allows the driver to drive on the ramp with his driving skill.

The transmission 1 for preventing sloping of shafts according to the embodiment of the present invention can prevent the vehicle from being pushed in the inclined road at the time of shifting the gear due to the coupling between the one-way clutch portion 40 and the synchromesh 60.

When the novice driver maintains the selection switch portion 82 in the ON state, the selection control portion 81 controls the one-way clutch portion 40 and the synchromesh 60. In the transmission 1 according to the embodiment of the present invention, It is possible to automatically prevent the vehicle from being pushed in the ramp.

The shift control apparatus 1 for preventing sloping of shafts according to the embodiment of the present invention is configured such that when the skilled operator holds the selection switch unit 82 in the off state, By blocking the meshing between the mesh portions 60, it is possible to travel by the driving skill of the driver skilled in the ramp.
