Description
Technical Field
[0001] The present application belongs to the technical field of engineering vehicles, and specifically relates to an engine assembly for an engineering vehicle. Background Art
[0002] Engineering vehicles are transport machinery used to transport materials such as ore and slag. They are generally powered by an engine or the electricity generated by the engine to drive the engineering vehicle.
[0003] At present, the engine of an engineering vehicle is generally installed at the bottom of the cab, and the engine oil filling port is usually set on the side of the engine. This will cause the cab to block the oil filling port, thereby increasing the difficulty for workers to add oil to the engine, thereby affecting the maintenance efficiency of the engine; at the same time, the cab will also block the oil dipstick, and the operating end of the oil dipstick is located at the bottom of the engine, which increases the difficulty for users to take out the oil dipstick, thereby affecting the user experience. Utility Model Content
[0004] The present application provides an engine assembly for construction machinery to reduce the difficulty of adding oil to the engine and improve the efficiency of engine maintenance; reduce the difficulty of the user in removing the oil dipstick and improve the user experience.
[0005] The technical solutions adopted in this application are:
[0006] An engine assembly for an engineering vehicle comprises an engine body, a filling pipe provided on the engine body, an extension pipe provided on the engine body, and an oil dipstick passing through the extension pipe, the filling pipe having an oil outlet end connected to an original oil filling opening of the engine body and an oil inlet end opposite to the oil outlet end, the oil outlet end being connected to the oil filling port of the engine body, the filling pipe extending upward from the oil outlet end to the oil inlet end, and the oil inlet end passing through the floor of a cab or being located outside the cab in a top view, the oil inlet end being detachably connected to an oil cap, the top end of the extension pipe extending toward the outside of a vehicle frame, and the end of the oil dipstick being capable of extending into the oil pan of the engine body.
[0007] By adopting the above technical solution, when adding oil to the engine, the oil cap is removed, and then the oil is poured into the oil inlet end so that the oil enters the engine along the filling pipe. Since the oil inlet end is penetrated through the floor of the cab or is projected outside the cab when viewed from above, the user can directly add oil in the cab or the oil inlet end and the cab avoid each other, thereby reducing the difficulty for the staff to add oil to the engine, thereby improving the maintenance efficiency of the engineering vehicle; and since the top end of the extension tube is extended toward the outside of the frame, the oil dipstick is pulled out closer to the outside of the cab, and at the same time the height for the user to operate the oil dipstick is raised, so that it is convenient for the user to pull out the oil dipstick to check the remaining oil amount, thereby greatly improving the user experience.
[0008] Optionally, it further includes a mounting bracket arranged on the vehicle frame, and the oil inlet end is arranged on the mounting bracket.
[0009] By adopting the above technical solution, since the oil inlet end is arranged on the mounting bracket, and the mounting bracket is arranged on the vehicle frame, the stability of the filling pipe is increased, and the vibration of the filling pipe during the driving of the engineering vehicle is reduced, thereby achieving the effect of extending the service life of the filling pipe; and it is avoided that when the oil is added to the engine through the filling pipe, the filling pipe shakes and causes oil to spill, thereby further reducing the difficulty of filling the engine with oil.
[0010] Optionally, the oil inlet end is connected to a connector, the connector is provided on the mounting bracket, and the oil cap is threadedly connected to the connector.
[0011] By adopting the above technical solution, since the connector is connected to the oil inlet end and the connector is arranged on the mounting bracket, the connection stability between the filling pipe and the mounting bracket is increased, thereby further ensuring the stability of the filling pipe.
[0012] Optionally, a connecting piece is provided on the side of the connecting head, and the connecting piece is fixedly connected to the mounting bracket.
[0013] By adopting the above technical solution, since the connecting piece is fixedly connected to the mounting bracket, the connection stability between the connecting head and the mounting bracket is increased, while the difficulty of connecting the connecting head and the mounting bracket is reduced, and the assembly efficiency of installing the connecting head on the mounting bracket is improved.
[0014] Optionally, the oil outlet is connected to a pipe joint, which is threadedly connected to the oil filling port of the engine body.
[0015] By adopting the above technical solution, since the oil outlet is connected to the oil filling port, the pipe joint is threadedly connected to the oil filling port of the engine body, thereby reducing the difficulty of connecting the filling pipe to the oil filling port of the engine, making it easier to modify the engine assembly and improve the sealing between the oil outlet and the oil filling port.
[0016] Optionally, the oil dipstick has a detection end that can be extended into the oil pan, the detection end is rotatably connected to a guide wheel, and the outer peripheral surface of the guide wheel is arranged flush with the end of the detection end.
[0017] By adopting the above technical solution, since the detection end is rotatably connected to the guide wheel, and the outer peripheral surface of the guide wheel is arranged flush with the end of the detection end, the guide wheel can guide the detection end when the oil dipstick is inserted into the extension tube, so as to increase the smoothness of the oil dipstick extending into the oil pan through the extension tube, thereby reducing the difficulty for the user to insert the oil dipstick into the extension tube, thereby further improving the user's experience.
[0018] Optionally, the detection end is provided with a receiving notch, and the guide wheel is provided in the receiving notch.
[0019] By adopting the above technical solution, since the guide wheel is arranged in the accommodating notch, the size of the detection end can be reduced to reduce the diameter of the extension tube. At the same time, the guiding effect of the guide wheel on the detection end can be increased to further increase the smoothness of the oil dipstick when it is extended into the extension tube.
[0020] Optionally, the oil dipstick has a detection end capable of extending into the oil pan, and the detection end is provided with a plurality of oil-blocking protrusions at intervals along the length direction of the oil dipstick.
[0021] By adopting the above technical solution, due to the presence of the extension tube, the path for pulling the oil dipstick out of the oil pan is extended, which causes the oil adhering to the detection end to easily fall back into the oil pan. By setting the oil-blocking protrusion, the speed of the oil falling and flowing back can be slowed down, so that the user can observe the remaining oil in the engine more accurately and clearly.
[0022] Optionally, a fixing bracket is further included, and one end of the top of the extension tube is connected to the fixing bracket.
[0023] By adopting the above technical solution, since the fixed bracket is arranged on the vehicle frame, one end of the top of the extension tube is connected to the fixed bracket, so that the fixed bracket can support the extension tube to increase the stability of the extension tube, and avoid the situation where the extension tube shakes when inserting the oil dipstick into the extension tube or pulling it out of the extension tube, which increases the difficulty of inserting or pulling out the oil dipstick, thereby ensuring the smoothness of the user's operation of the oil dipstick and thus ensuring the user's usage experience.
[0024] Optionally, a rotary joint is provided in communication with the oil drain port of the engine body, and an oil drain cap is detachably connected to the outlet of the rotary joint;
[0025] And / or, the oil inlet end is located between the cab and the vehicle compartment.
[0026] By adopting the above technical solution, since a rotary joint is provided at the oil drain port of the engine, the rotary joint can be rotated when the oil in the engine is discharged so that the outlet of the rotary joint is facing a position that is convenient for the staff to operate, thereby greatly reducing the difficulty of changing the oil and improving the maintenance efficiency of the engine assembly.

[0045] It is understood that the extension tube 3 communicates with the existing hole structure in the engine body 1 for inserting the oil dipstick 4, thereby reducing the modification cost of the engine assembly and simplifying the structure of the engine assembly. Of course, the extension tube 3 can also communicate with a hole structure newly provided in the engine body 1, as long as the oil dipstick 4 can be extended into the oil pan of the engine body 1 through the extension tube 3.
[0046] When adding oil to the engine, the oil cap 21 is removed, and then the oil is poured into the oil inlet end so that the oil enters the engine along the filling pipe 2. Since the oil inlet end is passed through the bottom plate of the cab or is located outside the cab when viewed from above, the user can directly add oil while driving or the oil inlet end can avoid the cab, thereby reducing the difficulty for the staff to add oil to the engine, thereby improving the maintenance efficiency of the engineering vehicle; and since the top end of the extension tube 3 is extended toward the outside of the frame, the pull-out position of the oil dipstick 4 is closer to the outside of the cab, and at the same time the height for the user to operate the oil dipstick 4 is raised, so as to achieve the effect of making it easier for the user to pull out the oil dipstick 4 to check the remaining oil, thereby greatly improving the user experience.
[0047] The present application does not impose any specific restrictions on the specific location of the oil inlet. Preferably, the oil inlet is located between the cab and the vehicle body to further facilitate the user's refilling of the engine assembly with oil. At the same time, the cab and the vehicle body can protect the oil inlet, thereby extending the service life of the filling pipe 2. Of course, in other embodiments, the oil inlet can also be located on the side of the cab.
[0048] In a preferred embodiment, referring to Figure 1 and Figure 2 The engine assembly also includes a mounting bracket 5 provided on the vehicle frame, and the oil inlet end is provided on the mounting bracket 5, thereby increasing the stability of the filling pipe 2 and reducing the vibration of the filling pipe 2 during the driving of the engineering vehicle, so as to achieve the effect of extending the service life of the filling pipe 2; and avoiding the situation where the filling pipe 2 shakes and causes the oil to spill when the oil is added to the engine through the filling pipe 2, so as to further reduce the difficulty of filling the engine with oil.
[0049] The present application does not make any specific limitation on the connection method between the oil inlet end and the mounting bracket 5. Preferably, the oil inlet end is connected to a connector 22, the connector 22 is provided on the mounting bracket 5, and the oil cap 21 is threadedly connected to the connector 22; that is, the oil inlet end is fixedly connected to the mounting bracket 5 through the connector 22, thereby increasing the connection stability between the filling pipe 2 and the mounting bracket 5, so as to further ensure the stability of the filling pipe 2.
[0050] Further, refer to Figure 1 and Figure 2 A connecting piece 221 is provided on the side of the connecting head 22, and the connecting piece 221 is fixedly connected to the mounting bracket 5, thereby increasing the connection stability between the connecting head 22 and the mounting bracket 5, while reducing the connection difficulty between the connecting head 22 and the mounting bracket 5, and improving the assembly efficiency of installing the connecting head 22 on the mounting bracket 5.
[0051] Better, refer to Figure 1 and Figure 2The connecting piece 221 is fixedly connected to the mounting bracket 5 by a bolt pair, so as to facilitate the disassembly and assembly of the connecting head 22.
[0052] In other embodiments, the oil inlet end may also be directly fixedly connected to the mounting bracket 5 via a clamp or other fasteners.
[0053] The present application does not make any specific limitation on the connection method between the oil outlet and the engine. Preferably, the oil outlet is connected with a pipe joint, which is threadedly connected to the oil filling port of the engine body 1, thereby reducing the difficulty of connecting the filling pipe 2 and the oil filling port of the engine, so as to facilitate the modification and design of the engine assembly and increase the sealing between the oil outlet and the oil filling port.
[0054] Preferably, the oil outlet end is sleeved on the outside of the pipe joint and fixedly connected to the pipe joint by a clamp.
[0055] In other embodiments, the oil outlet end may also be connected to the oil filling port of the engine body 1 by welding or other communication methods.
[0056] Of course, the extension pipe 3 can also be connected to the engine body 1 through a pipe joint.
[0057] In a preferred embodiment, referring to Figure 4 and Figure 5 The oil dipstick 4 has a detection end that can be inserted into the oil pan. The detection end is rotatably connected to a guide wheel 41. The outer peripheral surface of the guide wheel 41 is flush with the end of the detection end. Then, when the oil dipstick 4 is inserted into the extension tube 3, the guide wheel 41 can guide the detection end to increase the smoothness of the oil dipstick 4 extending into the oil pan through the extension tube 3, thereby reducing the difficulty for the user to insert the oil dipstick 4 into the extension tube 3, thereby further improving the user experience.
[0058] Further, refer to Figure 4 and Figure 5 The detection end is provided with a receiving notch 42, and the guide wheel 41 is provided in the receiving notch 42, which can reduce the size of the detection end to reduce the diameter of the extension tube 3.

[0060] Due to the existence of the extension tube 3, the path for the oil dipstick 4 to be pulled out of the oil pan is extended, which causes the oil adhering to the detection end to easily fall back into the oil pan. By setting the oil-blocking protrusion 43, the speed of the oil falling and flowing back can be slowed down, so that the user can observe the remaining oil in the engine more accurately and more clearly. In addition, the setting of the oil-blocking protrusion 43 can also serve as a reference for the user when observing the remaining oil in the engine body 1, so that the user can clearly know the remaining oil in the engine body 1.
[0061] Better, refer to Figure 4 and Figure 5 The side of the oil-blocking protrusion 43 facing away from the detection end is a flat surface to increase the oil blocking effect, while the side of the oil-blocking protrusion 43 facing the detection end is an arc surface to avoid the oil dipstick 4 from getting stuck when being inserted into the extension tube 3.
[0062] In a preferred embodiment, referring to Figure 1 、 Figure 2 and Figure 3 The engine assembly also includes a fixed bracket 6, and one end of the top of the extension tube 3 is connected to the fixed bracket 6, so that the fixed bracket 6 can support the extension tube 3 to increase the stability of the extension tube 3, and avoid the situation where the oil dipstick 4 is inserted into or pulled out of the extension tube 3 due to shaking of the extension tube 3, which increases the difficulty of inserting or pulling out the oil dipstick 4, so as to ensure the smoothness of the user's operation of the oil dipstick 4 and thus ensure the user's usage experience.
[0063] The present application does not specifically limit the installation position of the fixing bracket 6. Preferably, the fixing bracket 6 is provided on the engine body 1 to facilitate the assembly of the engine assembly on the vehicle frame. In other embodiments, the fixing bracket 6 can also be provided on the vehicle frame.
