Description

Technical Field

[0001] This utility model relates to the field of hydraulic torque converter technology, specifically a dual-guide wheel hydraulic torque converter for forklifts. Background Technology

[0002] A hydraulic torque converter consists of a pump impeller, turbine, stator, and other auxiliary components. It is installed between the engine and the torque converter and uses hydraulic oil as the working medium. It plays the roles of transmitting torque, changing torque, and clutching. The transmission of power and amplification of torque are achieved through the continuous circulation of hydraulic oil in the inner cavity of the torque converter.

[0003] In traditional hydraulic torque converters, the inner cavity is filled with hydraulic oil, which circulates continuously within the converter to amplify and transmit power. There is a certain gap between the power shaft and the torque converter. Although traditional equipment is equipped with sealing devices, the sealing effect deteriorates over long-term use, leading to oil leaks. Furthermore, traditional equipment lacks leak detection, making it difficult to detect leaks in a timely manner and thus affecting the normal operation of the equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a dual-guide wheel hydraulic torque converter for forklifts, which has the advantages of convenient installation and oil level detection, thus solving the problems mentioned in the background section.

[0006] As a preferred technical solution of this utility model: the installation position of the pump wheel corresponds to the installation position of the turbine, and the outer wall of the output shaft passes through the inner cavity of the housing.

[0007] As a preferred technical solution of this utility model: the inner wall of the detection ring is in contact with the outer wall of the housing and the outer wall of the output shaft respectively, and the outer wall of the support rod is in contact with the outer wall of the output shaft.

[0008] As a preferred technical solution of this utility model: the outer wall of the oil-absorbing sponge is in contact with the outer wall of the output shaft, and the oil-absorbing sponge is made of polyurethane, and the detection sensor is an oil leakage sensing rope sensor.

[0009] As a preferred technical solution of this utility model: the signal transmitter and the controller are electrically connected, and the outer wall of the fixing bolt is threadedly connected to the inner wall of the fixing ring and the rotating ring respectively.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This dual-guide wheel hydraulic torque converter for forklifts uses a detection ring installed on the outer wall of the housing. By installing the detection ring at the connection between the output shaft and the housing, when a leak occurs between the housing and the output shaft, the oil can be absorbed by the oil-absorbing sponge and guided into the inner cavity of the oil-absorbing sponge. Subsequently, the detection sensor detects the oil, and timely determines the existence of oil leakage between the housing and the output shaft, avoiding the inability of traditional equipment to detect oil leakage in a timely manner.

[0013] 2. This dual-guide wheel hydraulic torque converter for forklifts uses a fixing plate on the outer wall of the detection ring. When the detection ring needs to be fixed, the fixing ring and the rotating ring are interlocked and connected with fixing bolts, thereby fixing the detection ring and making the installation and fixing of the detection ring more convenient.

[0021] Please see Figure 1 - Figure 5 A dual-guide wheel hydraulic torque converter for forklifts includes a housing 1, a fixed base 2 fixedly mounted on the outer wall of the housing 1, a pump wheel 3 fixedly mounted on the inner cavity of the housing 1, an output shaft 4 rotatably connected to the inner cavity of the housing 1, a turbine 5 fixedly mounted on the outer wall of the output shaft 4, a first guide wheel 6 mounted on the outer wall of the output shaft 4, a second guide wheel 7 mounted on the outer wall of the output shaft 4, a lock-up clutch 8 mounted on the inner cavity of the housing 1, a detection ring 9 mounted on the outer wall of the housing 1, and a support rod 10 fixedly mounted on the inner wall of the detection ring 9. An auxiliary roller 11 is rotatably connected to the outer wall of the rod 10. An oil-absorbing sponge 12 is fixedly mounted on the inner wall of the detection ring 9. A detection sensor 13 is installed on the outer wall of the oil-absorbing sponge 12. A controller 14 is fixedly mounted on the outer wall of the detection sensor 13. A signal transmitter 15 is fixedly mounted in the inner cavity of the detection ring 9. A fixing plate 16 is installed on the outer wall of the detection ring 9. A rotating ring 18 is installed on the outer wall of the fixing plate 16. A fixing ring 17 is rotatably connected to the outer wall of the rotating ring 18. A fixing bolt 19 is threadedly connected to the outer wall of the rotating ring 18.

[0022] In the above structure, by using the fixed seat 2 provided on the outer wall of the housing 1 and the pump wheel 3 provided on the inner wall of the housing 1, the outer wall of the housing 1 is connected to the engine drive disc, so that the housing 1 rotates with the rotation of the engine. As a result, the pump wheel 3 rotates, driving the oil in the inner cavity of the housing 1 to rotate, thereby generating centrifugal force during the rotation of the oil.

[0023] In a preferred embodiment: the pump wheel 3 is installed at a position corresponding to the turbine 5, and the outer wall of the output shaft 4 passes through the inner cavity of the housing 1.

[0024] In the above structure, the output shaft 4 and turbine 5 are installed in the inner cavity of the housing 1. When the pump wheel 3 rotates, it can drive the flow of liquid in the inner cavity of the housing 1, so that the liquid passes through the second guide wheel 7 and the first guide wheel 6 to drive the turbine 5, so that the turbine 5 rotates under the action of the liquid, thereby driving the rotation of the output shaft 4 and the turbine 5, and thus realizing the transmission of power.

[0025] In a preferred embodiment: the inner wall of the detection ring 9 contacts the outer walls of the housing 1 and the output shaft 4 respectively, and the outer wall of the support rod 10 contacts the outer wall of the output shaft 4.

[0026] In the above structure, the detection ring 9 provided on the outer wall of the housing 1 ensures that the outer walls of the support rod 10 and the oil-absorbing sponge 12 are in contact with the outer wall of the output shaft 4. During the operation of the output shaft 4, the gap between the housing 1 and the output shaft 4 can be detected under the action of the detection ring 9. When the oil in the inner cavity of the housing 1 leaks from the gap between the housing 1 and the output shaft 4, it can be detected in time under the action of the detection ring 9.

[0027] In a preferred embodiment: the outer wall of the oil-absorbing sponge 12 is in contact with the outer wall of the output shaft 4, and the oil-absorbing sponge 12 is made of polyurethane, and the detection sensor 13 is an oil leakage sensing rope sensor.

[0028] In the above structure, the oil-absorbing sponge 12 installed in the inner cavity of the detection ring 9 can absorb the oil leaking between the housing 1 and the output shaft 4 under the action of the oil-absorbing sponge 12, so that the oil enters the inner cavity of the back-absorbing sponge 12. Then, under the action of the detection sensor 13 installed in the inner cavity of the oil-absorbing sponge 12, the oil is checked in time, thereby realizing the detection of oil.

[0029] In a preferred embodiment: the signal transmitter 15 is electrically connected to the controller 14, and the outer wall of the fixing bolt 19 is threadedly connected to the inner wall of the fixing ring 17 and the rotating ring 18, respectively.

[0030] In the above structure, the fixed ring 17 and the rotating ring 18 are connected in series by the rotating ring 18 provided on the outer wall of the fixed ring 17 and the fixing bolt 19 provided on the inner wall of the fixed ring 17 and the rotating ring 18, thereby fixing the fixing plate 16 under the action of the fixed ring 17 and the rotating ring 18, ensuring that the detection ring 9 can be stably installed on the outer wall of the housing 1.

[0031] In a preferred embodiment: the outer wall of the auxiliary roller 11 is in contact with the outer wall of the output shaft 4, there are three fixing plates 16, and the three fixing plates 16 are respectively installed on the outer wall of the detection ring 9, and the inner cavity of the housing 1 is filled with oil.

[0032] In the above structure, the support rod 10 and auxiliary roller 11 set in the inner cavity of the detection ring 9 can drive the auxiliary roller 11 to rotate when the output shaft 4 rotates, so that the auxiliary roller 11 and the output shaft 4 have rolling friction, thereby reducing the wear of the equipment and making it easier to detect the leakage between the output shaft 4 and the housing 1.

[0033] Working Principle: During operation, the aforementioned device mounts the housing 1 onto the engine drive plate and the output shaft 4 onto the gearbox. When the engine is running, the housing 1 rotates. This rotation of the housing 1 drives the rotation of the pump wheel 3, causing the oil inside the housing 1 to rotate and generate centrifugal force. This force propels the oil through the inner cavities of the second guide wheel 7 and the first guide wheel 6, acting on the turbine 5. The turbine 5 then rotates within the housing 1. Since the turbine 5 is mounted on the outer wall of the output shaft 4, it drives the output shaft 4, thus... The engine's power is transmitted to the gearbox, and during the rotation of the output shaft 4, there is a certain gap between the outer wall of the output shaft 4 and the inner wall of the housing 1. If the oil in the inner cavity of the housing 1 leaks outward, the oil will be absorbed by the oil-absorbing sponge 12. At this time, there will be oil in the inner cavity of the oil-absorbing sponge 12. Subsequently, the presence of oil is detected by the detection sensor 13, and an electrical signal is transmitted to the signal transmitter 15 through the controller 14. Under the action of the signal transmitter 15, an early warning is issued in time, thereby timely detecting the oil leakage between the housing 1 and the gearbox.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
