Description

Technical Field

[0001] This utility model relates to the field of transmission device technology, and in particular to a rapid testing device for hydraulic torque converters. Background Technology

[0002] A hydraulic torque converter, also known as a "hydraulic torque converter," "turbine torque converter," or "hydrodynamic torque converter," is a type of hydraulic transmission component consisting of a pump impeller, a turbine, and guide wheels. The pump impeller, connected to the drive shaft, converts the mechanical energy input from the drive shaft into the kinetic energy and pressure head of the liquid through centrifugal force, powering the turbine. The turbine, connected to the driven shaft, outputs the kinetic energy and pressure head contained in the liquid.

[0003] Therefore, it is particularly important to regularly check whether the hydraulic torque converter is in good condition. Utility Model Content

[0004] The purpose of this invention is to provide a rapid testing device for hydraulic torque converters to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A rapid testing device for a hydraulic torque converter includes a hydraulic torque converter, a testing device, and a warning device. The testing device includes a first identification area, a second identification area, and a counter. The first identification area is fixedly installed on the output shaft of the hydraulic torque converter, and the second identification area is fixedly installed on the input shaft of the hydraulic torque converter. A bearing is sleeved on the input shaft of the hydraulic torque converter, and a fixed support frame is sleeved on the outer ring of the bearing. The counter is fixedly installed on the fixed support frame. Two counters are provided, and the two counters are used to detect the number of rotations of the input shaft and the number of rotations of the output shaft within the same time period, respectively.

[0007] By adopting the above technical solution, the most important aspect of the hydraulic torque converter is whether it can achieve effective power transmission. Therefore, if the number of rotations of the input shaft and the output shaft suddenly changes in a stable state, it indicates an abnormality at the power output end. At this time, it is necessary to use other auxiliary equipment to determine whether there is a problem with the hydraulic torque converter itself. This device is only used to detect the number of rotations of the input shaft and the output shaft in the same time period.

[0008] In a further embodiment, a nozzle and a supplementary light are fixedly installed at the top of the fixed support frame, one end of the nozzle is connected to one end of a hose, and the other end of the hose is connected to an air pump.

[0009] By adopting the above technical solution, the input and output shaft surfaces of the hydraulic torque converter are cleaned by timed spraying with an air pump, avoiding excessive dust accumulation that could cause the first and second recognition areas to malfunction.

[0010] In a further embodiment, the first identification area and the second identification area have the same structure. The first identification area includes an adhesive layer, a coloring layer and a coating layer. The adhesive layer is used to bond and fix the coloring layer to the hydraulic torque converter. The coating layer is used to coat the surface of the coloring layer. The coating layer is made of a high-strength transparent material. The surface of the coating layer is provided with arc-shaped guide grooves at equal intervals along the axial direction of the output shaft.

[0011] By adopting the above technical solution, the arc-shaped guide groove allows the dust and oil stains attached to the surface of the input shaft or output shaft to be flung away along the guide direction of the arc-shaped groove under the action of centrifugal force when the shaft rotates at high speed, thereby ensuring a certain self-cleaning capability of the recognition area.

[0012] In a further embodiment, at least two first identification areas and at least two second identification areas are provided.

[0013] By adopting the above technical solution, and by symmetrically distributing the first identification area and the second identification area on the input shaft and the output shaft, the input and output shafts of the hydraulic torque converter will not vibrate due to gravity imbalance when rotating at high speed.

[0014] In a further embodiment, the warning device is a three-color warning light, the three-color warning light has a control module inside, and the counter is connected to the control module of the three-color warning light via a wiring harness.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. The most important aspect of a hydraulic torque converter is its ability to achieve effective power transmission. Therefore, if the number of rotations of the input shaft and the output shaft suddenly changes from a stable state, it indicates an abnormality at the power output end. In this case, it is necessary to use other auxiliary equipment to determine whether there is a problem with the hydraulic torque converter itself. This device is only used to detect the number of rotations of the input shaft and the output shaft within the same time period. Attached Figure Description

[0022] Example 1:

[0023] like Figures 1-2As shown, a rapid detection device for a hydraulic torque converter includes a hydraulic torque converter, a detection device 1, and a warning device 2. The detection device 1 includes a first identification area 11, a second identification area 12, and a counter 13. The first identification area 11 is fixedly installed on the output shaft of the hydraulic torque converter, and the second identification area 12 is fixedly installed on the input shaft of the hydraulic torque converter. A bearing is sleeved on the input shaft of the hydraulic torque converter, and a fixed support frame is sleeved on the outer ring of the bearing. The counter 13 is fixedly installed on the fixed support frame. Two counters 13 are provided, and the two counters 13 are used to detect the number of rotations of the input shaft and the number of rotations of the output shaft within the same time period, respectively. A nozzle and a supplementary light are fixedly installed on the top of the fixed support frame. One end of the nozzle is connected to one end of a hose, and the other end of the hose is connected to an air pump. The first identification area 11 and the second identification area 12 are fixedly installed on the output shaft. The structure of zone 12 is consistent. The first identification zone 11 includes an adhesive layer, a coloring layer, and a coating layer. The adhesive layer is used to bond and fix the coloring layer to the hydraulic torque converter. The coating layer is used to coat the surface of the coloring layer. The coating layer is made of a high-strength transparent material. The surface of the coating layer is provided with arc-shaped guide grooves at equal intervals along the axial direction of the output shaft. When the input shaft or output shaft rotates at high speed, the dust and oil stains attached to its surface will be thrown away along the guide direction of the arc-shaped grooves under the action of centrifugal force, thereby ensuring a certain self-cleaning ability of the identification zone. There are at least two first identification zones 11 and at least two second identification zones 12. The warning device 2 is a three-color warning light. The three-color warning light has a control module inside. The counter 13 is connected to the control module of the three-color warning light by wired signal through a wiring harness.

Therefore, if the number of rotations of the input shaft and the output shaft suddenly changes in a stable state, it indicates an abnormality at the power output end. At this time, it is necessary to use other auxiliary equipment to determine whether there is a problem with the hydraulic torque converter itself. This device is only used to detect the number of rotations of the input shaft and the output shaft within the same time period.
