Description of the Invention: [Technical Field] The present invention relates to a parking device, and more particularly to a parking device for a vehicle. [Prior Art] Referring to FIG. 1, a conventional parking device 2 is mounted on an all-terrain vehicle 1 including a handle u and an axle 12 driven by an engine (not shown). The parking device 2 includes a triggering member 21 disposed on the handle n, and a parking unit 22 for clamping the axle 32. §海车车兀22 includes a brake caliper 221′ disposed adjacent to the wheel end of the rear rocker arm (not shown) and a linkage cable 222 respectively connected to the brake caliper 221 and the trigger member 21 at both ends, When the trigger member 21 is in an open position, the axle 12 is in a rotatable state; and when the trigger member 21 is pulled in the direction of the arrow 100, the shell pulls the linkage 222 to pull the brake 221 The brake shoe 223 is moved in the direction indicated by the arrow 1-1 to brake the axle 12 so that the axle 12 cannot rotate to achieve the parking effect. However, since the rotation speed of the axle 12 is low and the torque is large, the required braking torque is also large. If the braking effect on the axle 12 is poor, the existing brake tongs 221 are installed in a single type. The axle 12' is only designed with its own maximum load. For additional additional loads, or when the vehicle itself is too heavy, the parking requirement cannot be achieved. Moreover, the current German regulations stipulate that the parking test must be able to park without stopping at 25% (about Η inclination) = maximum technical load + trailer weight 〇 4 times the maximum technical load to meet regulatory standards. Therefore, the single 煞 201132539 car sweet 221 is set on the axle ι2, which cannot meet the regulatory standards. Not only the parking effect is poor, but also the present invention. Accordingly, the object of the present invention is to provide a parking device for a powered vehicle. The parking device of the vehicle of the present invention is suitable for a vehicle, and the vehicle includes an engine and a transmission device driven by the engine includes: a flat member and a trigger member disposed on the vehicle In the vehicle, the early 6-high trigger member can be moved between the open position and a parking position; a first parking line is driven by the trigger member; and a distribution unit is connected to the first parking line; The second parking line is respectively connected to the distribution unit, the parking line is driven, and the second card is respectively driven by the second parking line. When the trigger is located at the open position, the second card is The transmission is not braked so that the transmission can be rotated 'when the trigger is in the parking position, the two calipers brake the transmission so that the transmission cannot rotate. The utility model has the advantages that the two calipers are used at the same time, not only can the braking force be improved, but the calipers are all provided with the functions of braking and parking, and: the braking device and the parking device directly brake the transmission device, and can provide better Braking effect.
