Description

Technical Field

[0001] The utility model relates to a heavy truck coolant degassing mechanism and a vehicle, belonging to the field of heavy truck water cooling systems. Background Art

[0002] At present, the water cooling system of heavy trucks is a forced water circulation system, that is, a water pump is used to increase the capacity of the coolant and force the coolant to circulate inside the engine. In this system, a pipeline is usually set at the water inlet of the water pump to connect the water filling port of the expansion tank. When the water is filled through the expansion tank, gas will accumulate inside the water cooling system. It is necessary to set a degassing pipeline to discharge the gas inside the water cooling system through the expansion tank assembly.

[0003] At present, the radiator of heavy trucks is installed on the chassis. When the expansion tank is installed on the cab, the degassing pipeline needs to be designed to be longer due to the need for the cab to flip, so as to avoid the pipeline being broken by force or affecting the cab flipping when the cab flips. The existing degassing pipeline is not installed properly, and it is easy to interfere with and wear other parts of the vehicle when the cab flips. Summary of the invention

[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides a heavy-duty truck coolant degassing mechanism and a vehicle, which ensures that the degassing pipeline can be reliably fixed without interfering with and wearing other components when the vehicle is driving, stationary or when the cab is flipped.

[0010] In some embodiments, one end of the degassing steel pipe is provided with a bending portion for placing the degassing pipe.

[0011] In some embodiments, a rubber sheath is installed on one end of the degassing steel pipe having a bent portion.

[0012] In some embodiments, the spring assembly includes a stop plate, a spring, and a spring washer;

[0013] The spring washer is installed on the fixed bracket I and is located at the bottom of the spring. The limit plate is coaxially fixed on the degassing steel pipe. The end of the degassing steel pipe extends through the spring, the center of the spring washer and the fixed bracket I in sequence. The two ends of the spring are respectively connected to the degassing steel pipe and the fixed bracket I, so as to provide the degassing steel pipe with a restoring elastic force.
