Description

Technical Field

[0001] This utility model belongs to the field of brake spring technology, specifically relating to a brake spring life testing device. Background Technology

[0002] The springs of servo motor brakes are prone to fatigue failure under frequent start-stop or emergency braking conditions, requiring reliability testing of their lifespan. Current technologies often rely on manual operation or general-purpose fatigue testing machines, which presents the following problems: manual testing is inefficient, cannot accurately simulate the cycle frequency and load of actual operating conditions, and traditional equipment is difficult to adapt to springs of different specifications, resulting in poor compatibility. Utility Model Content

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0004] A brake spring life testing device includes a frame body and a first fixed end and a second fixed end mounted on the frame body, wherein the two ends of a plurality of springs are respectively connected to the first fixed end and the second fixed end.

[0005] The first fixed end includes a first driving element and a sliding platform connected to the output end of the first driving element. A first fixed plate is detachably connected to the sliding platform. The first fixed plate is provided with a plurality of first connecting buckles, which are used to connect one end of the spring.

[0006] The second fixed end includes a second driving element and a slider connected to the output end of the second driving element. The slider is provided with a third driving element. The third driving element is connected to a plurality of second connecting buckles through a transmission element. The second connecting buckles are used to connect one end of the spring.

[0007] Furthermore, the sliding platform is a lead screw sliding module, and the first driving element is fixedly connected to the lead screw. When the first driving element drives the lead screw to rotate, it can drive the first fixed plate to slide forward / backward.

[0008] Furthermore, the sliding platform is fixed to the first fixed plate by nuts.

[0009] Furthermore, the transmission element is a gear set, which includes a driving wheel and a number of driven wheels that are the same number as the second connecting buckles. The driving wheel is fixedly connected to the third driving element, and the number of driven wheels are fixedly connected to the second connecting buckles respectively. The driven wheels mesh with the driving wheel respectively. When the third driving element drives the driving wheel to rotate, it can drive the number of second connecting buckles to rotate.

[0010] Furthermore, the first and second connecting buckles are handle-shaped or circular.

[0011] Furthermore, the first driving element and the third driving element are motors.

[0012] Furthermore, the second driving element is a cylinder.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model uses two ends to fix multiple springs. One end can move back and forth, and the other end can move up and down. It can simulate various working conditions such as stretching, compression, and tilting stretching, and obtain damage data of springs under various operating states.

[0015] 2. This utility model also uses a gear to drive one of the fixed ends to rotate, so that each spring can rotate relative to its own center, which can quickly test the torque parameters of multiple springs.

[0016] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.
