Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of engine, more specifically, it relates to a motorcycle engine oil cooler water pipe limiting structure. BACKGROUND

[0002] The motorcycle engine oil cooler (Oil Cooler) is an important part of the liquid cooling system, which is used for cooling the engine lubricating oil (machine oil) to ensure that the engine can maintain good lubricating performance and working temperature under high temperature conditions. And the oil cooler needs to be communicated with the oil cooler water pipe, and the cooling of the oil cooler is carried out through the cooling liquid in the oil cooler water pipe, therefore, the oil cooler water pipe needs to be arranged.

[0003] The engine external pipeline in the prior art is usually fixed on the crankcase by using a wire clamp, and the wire clamp is prone to aging and falling off after long-term use, so that the oil cooler water pipe is prone to loosen. In addition, the oil cooler water pipe is fixed on the surface of the engine by the wire clamp, so that the structure of the surface of the engine looks more complex, which affects the arrangement of other related structures.

[0004] For example, the patent for utility model with publication number CN219220549U, published on June 20, 2023, the name of the invention is engine assembly and motorcycle. In this application, the wire clamp is used to fix the oil cooler water pipe and other water pipes. Although the installation is more convenient, the wire clamp is prone to aging and falling off after long-term use. CONTENT OF UTILITY MODEL

[0005] The utility model overcomes the problem that the oil cooler water pipe is fixed by the wire clamp in the prior art, and the wire clamp is prone to aging and falling off after long-term use. A motorcycle engine oil cooler water pipe limiting structure is provided, which sets a fixing structure on the body of the motorcycle engine to fix the oil cooler water pipe, and firmly fixes the oil cooler water pipe on the body of the motorcycle engine, so that the overall structure of the motorcycle engine can be more compact, and the strength of the motorcycle engine hanging point can be increased.

[0006] In order to solve the above technical problems, the utility model adopts the following technical scheme: a motorcycle engine oil cooler water pipe limiting structure, comprising: a crankcase, a fixing structure is arranged on the crankcase, the fixing structure comprises a fixing rod, one end of the fixing rod is fixedly connected with the crankcase, and the other end of the fixing rod is connected with an engine hanging point; a fixing hole is formed between the fixing rod and the crankcase, and the oil cooler water pipe is arranged in the fixing hole.

[0007] The fixing structure in the application cooperates with one of the engine hanging points to form a fixing hole, the oil cooler water pipe passes through the fixing hole, and the oil cooler water pipe is fixed through the fixing hole, thereby avoiding the trouble of fixing the oil cooler water pipe through a wire clamp, and the overall structure can be more compact; and since the fixing structure is integrally formed with the crankcase, the fixing hole will not be damaged or worn due to long-term use, and the fixing rod connects the engine hanging point and the crankcase, thereby improving the strength of the engine hanging point and enabling the engine hanging point to bear greater load.

[0008] Preferably, the engine hanging point comprises a hanging rod fixedly connected with the crankcase, and a plurality of reinforcing ribs are arranged on one side of the hanging rod.

[0009] The reinforcing ribs can improve the connection strength between the hanging rod and the crankcase, and also improve the load-bearing capacity of the hanging rod, so that the motorcycle engine can be more stably installed on the motorcycle frame through the hanging rod.

[0010] Preferably, a reinforcing groove is arranged on the other side of the hanging rod away from the reinforcing ribs.

[0011] The arrangement of the reinforcing groove not only reduces the weight of the hanging rod and reduces the overall weight of the motorcycle engine, but also forms a rib-like structure on both sides of the groove, thereby improving the strength of the hanging rod and enabling the hanging rod to bear greater load.

[0012] Preferably, two reinforcing ribs are arranged, and the two reinforcing ribs are arranged along the width direction of the fixing rod.

[0013] The arrangement of the two reinforcing ribs along the width direction of the fixing rod improves the connection strength of the hanging rod and enables the hanging rod to bear greater load.

[0014] Preferably, a weight-reducing hole penetrating through the hanging rod is arranged in the reinforcing groove.

[0015] The weight-reducing hole can reduce the weight of the hanging rod and reduce the overall weight of the motorcycle engine.

[0016] Preferably, an inwardly concave circular arc segment is arranged on the side of the reinforcing groove close to the fixing hole.

[0017] The arrangement of the circular arc segment facilitates the adaptation of the oil cooling pipe after bending to the circular arc segment, so that the oil cooling pipe can abut against the circular arc segment.

[0018] Preferably, the oil cooler is further arranged on the side of the crankcase close to the fixing structure.

[0019] The above structure facilitates the passing of the oil cooler water pipe through the fixing hole and better fixation of the oil cooler water pipe.

[0020] Preferably, the opening of the fixing hole gradually narrows along its length direction.

[0021] The opening size of the fixing hole gradually changes along its length direction, and the oil cooler water pipe can conveniently pass through the fixing hole at the large one end of the opening, and can be pushed into the small one end of the opening after passing through the fixing hole, and the oil cooler water pipe is fixed by the small one end of the opening in the fixing hole, and then the second oil cooler water pipe passes through the fixing hole, so that the oil cooler water pipe can conveniently pass through the fixing hole, and the small one end of the fixing hole also facilitates the fixing of the oil cooler water pipe.

[0022] Compared with the prior art, the beneficial effects of the utility model are that: the fixing structure in the application cooperates with one of the engine hanging points to form a fixing hole, the oil cooler water pipe passes through the fixing hole, and the oil cooler water pipe is fixed by the fixing hole, thereby saving the trouble of fixing the oil cooler water pipe by wire clamps, and the overall structure can be more compact; and since the fixing structure is integrally formed with the crankcase, the fixing hole will not be damaged or worn due to long-term use, and the fixing rod connects the engine hanging point and the crankcase, which can improve the strength of the engine hanging point and enable the engine hanging point to bear greater load.
