A vehicle according to an embodiment of the invention, which may be an all terrain vehicle, is described below with reference to the accompanying drawings.

As shown in fig. 3, a vehicle according to an embodiment of the present invention includes a frame 2 and a front axle mounting structure 1.

The front axle mounting structure 1 is mounted on the frame 2, wherein the part of the frame 2 around the front axle mounting structure 1 can be a metal plate combination.

A front axle mounting structure 1 according to an embodiment of the present invention is described first with reference to the drawings.

As shown in fig. 1 to 3, front axle mounting structure 1 includes a mounting bracket 100, a front axle 200, and a mounting base 300.

The mounting block 100 defines a mounting space 110 therein, and a lower surface of the mounting space 110 forms a mounting/dismounting opening 120. The front axle 200 is fitted in the installation space 110 and can enter and exit the installation space 110 through the attaching and detaching port 120. The mounting base 300 is mounted to the mounting bracket 100 and stops the front axle 200 within the mounting space 110 at the mounting/dismounting hole 120.

For example, the mounting bracket 100, the front axle 200, and the mounting base 300 are separately provided, and are detachable in the vertical direction of the front axle mounting structure 1. The mounting bracket 100 is mounted to the frame 2. The attachment/detachment opening 120 is provided downward, for example, below the bottom surface of the vehicle body frame 2 or flush with the bottom surface of the vehicle body frame 2, and the front axle 200 can be inserted into and removed from the mounting space 110 through the attachment/detachment opening 120. The mounting base 300 is exposed from the bottom surface of the vehicle frame 2.

According to the utility model discloses front axle mounting structure 1, through setting up mounting bracket 100, and set up the dismouting mouth 120 that supplies front axle 200 business turn over at the lower surface of mounting bracket 100, thereby make front axle 200 can carry out the dismouting from the bottom surface of frame 2, the loading and unloading of front axle 200 do not receive the influence of other parts on the frame 2 like this, front axle 200 loading and unloading are convenient, and front axle 200 takes out from the bottom surface of frame 2, can make the structural design of frame 2 more nimble, front axle 200 is more pressed close to the structure and the peripheral part of frame 2, make front axle mounting structure 1's compact structure. The mounting bracket 100, the front axle 200 and the mounting base 300 are arranged in a split structure, the front axle mounting structure 1 is simple in structure, and the front axle 200 is convenient and quick to maintain and repair.

According to the utility model discloses front axle mounting structure 1 and vehicle have front axle 200's dismouting and advantage such as maintenance convenience.

According to some embodiments of the present invention, as shown in fig. 2, the mounting frame 100 is provided with the support rib 130, the mounting base 300 is provided with the support edge 320, and the support edge 320 is supported on the support rib 130. During assembly, the mounting base 300 screws the front axle 200 into the mounting space 110 using the support rib 130 as a fulcrum.

Specifically, the mounting bracket 100 has a rear bottom cross member 140 located at the rear lower portion thereof, the rear bottom cross member 140 extends in the left-right direction, the support rib 130 is provided on the rear bottom cross member 140 and extends in the longitudinal direction of the rear bottom cross member 140, and the support rib 320 is provided on the rear edge of the mounting base 300.

For example, the rear bottom cross member 140 may be a cylinder, and the rear bottom cross member 140 is connected to the frame 2. The support rib 130 is provided forward and upward of the rear floor cross member 140 and faces the installation space 110. So, during the assembly, can take 320 along the support rib 130 of mounting bracket 100 with the support of installation base 300, so use support rib 130 as the fulcrum, rotate installation base 300, thereby the front axle 200 with on the installation base 300 changes into installation space 110, can make things convenient for assembly personnel's operation like this, for example, will support and take 320 back on mounting bracket 100, but operating personnel one hand holds installation base 300 and rotates, rotate to the position after, fasten with the other hand, that is to say, the dismouting of front axle 200 can be accomplished to single.

Further, as shown in fig. 1-3, mounting base 300 is fastened to the bottom of front axle 200 by bottom fasteners 310.

Specifically, the bottom fastener 310 may be a threaded fastener, such as a bolt, and the bottom fastener 310 is plural. The bottom fastener 310 is installed at the bottom of the front axle 200 through the lower side of the installation base 300. Thus, before the supporting edge 320 of the mounting base 300 is lapped on the supporting rib 130 of the mounting rack 100, the mounting base 300 and the front axle 200 can be fixed into a whole through the bottom fastener 310, the bottom fastener 310 can prevent the mounting base 300 and the front axle 200 from moving relatively, the supporting of the mounting base 300 on the front axle 200 is strengthened, and the subsequent lifting and rotating operation is facilitated.
