Description

Technical Field

[0001] This utility model relates to the field of power take-off technology, specifically a power take-off with high safety. Background Technology

[0002] The power take-off (PTO) is an auxiliary device mounted on the outside of the gearbox (in cement mixer trucks, the PTO is on the clutch housing), and it obtains power from a gear in the gearbox. This power is engaged or disengaged via an electromagnetic valve located in the cab. The PTO powers a high-pressure oil pump for dump trucks; a water pump for fire trucks; a compressor for refrigeration trucks; and a hydraulic motor to rotate the mixing tank.

[0003] When using existing power take-offs (PTOs), as key components for power transmission in vehicles or construction machinery, monitoring their internal temperature is an important means to ensure stable operation and prevent malfunctions. However, existing PTOs lack internal temperature monitoring components. If the internal temperature is too high, it can lead to the failure of internal lubricating oil and thermal deformation of components, resulting in damage.

[0004] In view of this, it is necessary to develop a highly safe power take-off unit that can monitor the internal temperature of the power take-off unit in real time. Utility Model Content

[0005] The purpose of this utility model is to provide a highly safe power take-off unit to solve the technical problem mentioned in the background art that the existing power take-off units lack a monitoring component for internal temperature, which can lead to internal lubricating oil failure and component thermal deformation and damage if the internal temperature is too high.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-safety power take-off (PTO), comprising: a PTO rear housing, wherein multiple sets of temperature monitoring components are installed on the outer inner wall of the PTO rear housing, the temperature monitoring components including an embedding groove, an embedded temperature probe, a sealing ring, a display, a display screen, and a circuit connector, the embedding groove being formed on the outer inner wall of the PTO rear housing, the embedded temperature probe being embedded inside the embedding groove, a sealing ring being installed between the embedding groove and the embedded temperature probe, the display being installed on the top of the PTO rear housing, the display screen being installed on the top of the PTO rear housing, and a circuit connector electrically connected to the embedded temperature probe being installed on one side of the PTO rear housing.

[0007] Preferably, a shift fork shaft is installed on the top inner side of the power take-off housing, multiple springs are symmetrically installed on the outer side of the shift fork shaft, and an O-ring is installed on the outer side of one end of the shift fork shaft.

[0008] Preferably, a cylinder head gasket is installed on one side of the rear housing of the power take-off, and a cylinder head body is installed on one side of the rear housing of the power take-off via the cylinder head gasket.

[0009] Preferably, an output gear shaft is rotatably mounted on the inner bottom side of the power take-off housing.

[0010] Preferably, a front housing of the power take-off is bolted to one side of the rear housing of the power take-off, and a fork body and an elastic cylindrical pin are respectively installed inside the front housing of the power take-off.

[0011] Preferably, a first retainer assembly and a second retainer assembly are respectively installed inside the front housing of the power take-off. A drive gear is installed on the outside of the first retainer assembly, a sliding sleeve is installed on the outside of the drive gear, an input shaft is installed at one end of the drive gear, and a cylindrical roller bearing is installed on one side of the second retainer assembly.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the embedded temperature probe can be installed on the inner wall of the power take-off (PTO) rear housing through an embedding slot, with the monitoring end of the embedded temperature probe facing the inside of the PTO. This allows the embedded temperature probe to monitor the internal temperature of the PTO in real time. Because the embedded temperature probe is embedded inside the embedding slot, it can be used inside the PTO. The temperature value monitored by the embedded temperature probe is displayed on a screen on an external monitor, allowing operators to observe the internal temperature of the PTO. If the internal temperature is too high, it can be observed and identified, preventing damage to the PTO due to undetected overheating, thereby improving the safety of the PTO.
