Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the present invention is further described in detail by the following embodiments with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The embodiment of the utility model provides a plate spring seat, as shown in fig. 1, including the U-shaped body 101, the middle part of the U-shaped body 101 is straight installation end 1011, installation end 1011 is used for installing the middle region of the plate spring, the two sides of the U-shaped body 101 are symmetrical bending ends 1012, the bending ends 1012 are used for fixedly connecting with the side wall of the drive axle; the supporting body 102 is used for increasing a reserved space between the U-shaped body 101 and the drive axle and can also support the U-shaped body 101, so that the overall strength is improved and large bearing capacity is met, the supporting body 102 is provided with a straight supporting end 1021 and an arc adjusting end 1022, the supporting end 1021 is used for improving the supporting capacity of the U-shaped body 101, the arc adjusting end 1022 is used for adjusting the fixing position of a bent end 1012 and the side wall of the drive axle, the bent end 1012 can be welded and fixed in an area with small stress on the side wall of the drive axle, and weak parts above and below the bridge body with large stress on the drive axle are avoided; the joint of the arc-shaped adjusting end 1022 and the inner wall of the U-shaped body 101 is provided with a first welding seam 103, the joint of the support end 1021 and the inner wall of the U-shaped body 101 is provided with a second welding seam 104, and the arc-shaped adjusting end 1022, the support end 1021 and the inner wall of the U-shaped body 101 are fixed by welding at the first welding seam 103 and the second welding seam 104 respectively.
