The invention specifically discloses a heavy automobile transmission and oil cooler pipeline locking device, aiming at solving the problem that scrapping of the transmission is caused so as to cause potential safety hazard because an oil leakage phenomenon easily occurs in an oil pipe between a conventional transmission and an oil cooler. The heavy automobile transmission and oil cooler pipeline locking device comprises a locking base, wherein a locking groove is formed in the locking base; an oil inlet hole groove and an oil return hole groove are formed in the upper side of the locking groove; an oil return hole groove I and an oil inlet hole groove I are formed in the lower side of the locking groove; an electromagnetic valve core is arranged in the locking groove; two raised rings are arranged on the electromagnetic valve core; an oil duct is formed in the inner end of the electromagnetic valve core; an electromagnetic valve coil is arranged on the outer side of the electromagnetic valve core; a return spring is arranged at the inner end of the electromagnetic valve core; a pressure switch is arranged on the oil return hole groove I; a relay connected with the coil is arranged at the output end of the pressure switch; a contact of the relay is connected with the electromagnetic valve coil; the contact of the relay is connected with a buzzer positioned in a cab. Oil leakage alarm and a function of timely locking the oil duct are realized, and the reliability of a vehicle is greatly improved.
Description
technical field [0001] The invention relates to a locking device for a heavy-duty vehicle, in particular to a pipeline locking device for a transmission oil cooler of a heavy-duty vehicle. Background technique [0002] With the development of domestic heavy-duty vehicle transmissions, more and more applications of external oil coolers are used in the actual design of heavy-duty vehicle transmissions. The use of external oil coolers is to provide good transmission operating temperature and increase It increases the complexity of the transmission system and increases the frequency of failures. The main reason is that the oil leakage occurs due to the quality of the oil pipe itself and the installation technology. However, this oil leakage is difficult to find and repair in time when the vehicle is running. Cause the lubricating oil of speed changer to leak dry in a very short time, cause speed changer to be scrapped therefore, greatly endanger the normal running of vehicle and...
