The adjusting assembly 40 is disposed between the second supporting assembly 30 and the leaf spring to adjust a distance between the leaf spring and the second supporting assembly 30.

The leaf spring mounting device 100 is used to mount a leaf spring to a vehicle frame. One end of the steel plate spring along the longitudinal direction is connected with a fixed point on the frame, and the other end is connected with a movable point on the frame. In addition, the leaf spring has an arc-shaped structure, and when the leaf spring is subjected to a pressure in the thickness direction thereof, the curvature of the leaf spring changes, thereby causing the length thereof to change. Therefore, in order to reserve a changing space for the leaf spring in the length direction, one end of the leaf spring in the length direction is connected with a movable point on the frame, so that the leaf spring can move along the length direction conveniently.

Leaf spring supports respectively on first supporting component 20 and second supporting component 30 along its lengthwise direction's both ends for leaf spring can the stable stay along its lengthwise direction's both ends, avoids leaf spring to take place the skew in the installation, improves the security and the high efficiency of assembling process.

When connecting the other end on the second supporting component 30, can adjust leaf spring and the ascending distance of second supporting component 30 in vertical direction through control adjusting part 40 for leaf spring supports the other end on second supporting component 30 and is connected smoothly with the movable point on the frame, improves assembly efficiency.

In some embodiments, the adjustment assembly 40 includes an adjustment member 41, and the adjustment member 41 is movably connected between the second support assembly 30 and the leaf spring in the vertical direction to adjust the distance between the leaf spring and the second support assembly 30 in the vertical direction.

Specifically, the adjusting member 41 is supported between the second support assembly 30 and the leaf spring in the vertical direction. The distance between the leaf spring and the second support assembly 30 is adjusted, that is, the support height of the leaf spring on the main body 10 is adjusted. At this time, the support height of the leaf spring can be adjusted by adjusting the moving distance of the adjusting member 41 in the vertical direction, so as to connect the leaf spring to the moving point of the vehicle frame.

Further, the adjusting assembly 40 includes a transmission member 42, the transmission member 42 is movably disposed on the second supporting assembly 30 or the main body 10, and the transmission member 42 is controlled to adjust a moving distance of the adjusting member 41 in the vertical direction.
