The engine 131 is disposed in a space surrounded by the first main beam 111, the second main beam 112, the third main beam 113, and the fourth main beam 114, and is connected to the first cross beam 111 by a connecting member 132. As can be understood, in the prior art, for the fixation of the engine 131, a connecting part is usually disposed below the engine 131 to be fixedly connected with the frame 11, and the engine 131 is mounted on the frame 11 through the connecting part, so that the engine and peripheral accessories are prone to interference, abnormal noise and other problems during extreme operating conditions, and further the safety of the whole vehicle is affected, and therefore, a limiting structure needs to be disposed above the engine 131. In this embodiment, the atv 100 further includes a limiting structure 16, and the limiting structure 16 is disposed on the first main beam 111 for fixing the position of the engine 131 and isolating the vibration of the engine 131 from being transmitted to the whole vehicle. Of course, in other embodiments, the stop structure 16 may be disposed on the second main beam 112.

As shown in fig. 3 to 5, the limiting structure 16 includes a first connecting member 161, a shock absorbing member 162, a second connecting member 163, a limiting bracket 164, a first fixing member 165, a second fixing member 166, and a third fixing member 167.

In this embodiment, the fixing member may be a bolt and a nut, or may be other combined fixing members, such as a bolt, a buckle, and the like. The number of the studs of the third fixing member 167 is two, so that the bearing capacity is more stable and the stud is not easy to shake, but in other embodiments, the number of the studs of the third fixing member 167 may be other numbers, and the number of the mounting holes on the second connecting member is correspondingly changed as long as the same effect can be achieved, for example, the number of the studs of the third fixing member 167 may be one, three, four or five.
