Description

Technical Field

[0001] The utility model relates to a vehicle with a fixed-lock engine, in particular to a vehicle with a fixed-lock engine suitable for a two-wheeled motorcycle. Background Art

[0002] See also Figure 1 , which is a side view of a conventional vehicle with a swing engine. The figure shows a vehicle 90 with a swing engine, including a frame 91, a swing engine 92 and a rear wheel 98, wherein one end of the swing engine 92 is connected to the frame 91, and the other end is connected to the rear wheel 98, and may include a variable valve lift system (not shown), through which an oil control valve (not shown) is used to optimize the engine efficiency, environmental performance, and power characteristics, so that the power performance of the engine has variable characteristics.

[0003] However, since the engine and the frame will move relative to each other while the vehicle is moving, the dynamic driving response of the vehicle is easily affected, and the oil control valve of the variable valve lift system may also be affected. In addition, since the oil control valve is a relatively fragile electronic component, it may be damaged by foreign objects while the vehicle is moving, and when it is damaged, the engine will leak oil, which will affect the personal safety of the rider, so the protection of the oil control valve must be strengthened.

[0004] The inventor, in view of this, based on the spirit of active invention, has been eager to think of a vehicle with a locked engine that can solve the above-mentioned problems. After several studies and experiments, the present utility model is finally completed. Summary of the invention

[0005] The main purpose of the utility model is to provide a vehicle with a fixed-lock engine, which has a variable valve lift system. Compared with the existing vehicle design with a swing engine, in addition to improving the vehicle's driving performance, it also makes the configuration of the variable valve lift system more compact and improves the protection of the oil control valve.

[0006] In order to achieve the above-mentioned purpose, the vehicle with a fixed-lock engine of the utility model includes a frame, a fixed-lock engine and a water tank. The frame includes a main frame and a sub-frame connected to the main frame, the main frame includes a left main frame and a right main frame, the left main frame includes a first left main frame and a second left main frame, and the right main frame includes a first right main frame and a second right main frame. The fixed-lock engine assembly is arranged on the frame, including a crankcase, a cylinder head, a variable valve lift system, a crankshaft and a transmission shaft. The variable valve lift system is arranged on the cylinder head, and the oil circuit is controlled by an oil control valve to switch the power characteristics of the fixed-lock engine. The crankshaft is accommodated in the crankcase and connected to the transmission shaft through a stepless transmission system to transmit power output. The water tank assembly is arranged on the frame and is located in front of the fixed-lock engine. Among them, when observed from the front direction of the vehicle, the oil control valve is located in the area below the first left main frame, the first right main frame and above the axis of the crankshaft.

[0007] The above-mentioned variable valve lift system may include a camshaft assembly, an intake rocker arm group and a valve group. The intake rocker arm group may include a first rocker arm, a second rocker arm and a connecting mechanism. The connecting mechanism can be controlled by the oil circuit of the oil control valve to connect or separate the first rocker arm and the second rocker arm to switch the power characteristics of the fixed-lock engine.

[0008] For the vehicle with a locked engine, the oil control valve may be partially located behind the water tank when viewed from the front of the vehicle.

[0009] The vehicle with the fixed-lock engine may further include a spark plug disposed on the cylinder head.

[0010] For the vehicle with a fixed-lock engine, when viewed from the front of the vehicle, the oil control valve and the spark plug can be located on the same side of a central symmetry line of the vehicle.

[0011] The vehicle may be a one-speed accessible motorcycle.

[0012] The above-mentioned fixed-lock engine can be a single-cylinder engine.

[0013] With the above design, since the oil control valve is located behind the water tank, foreign objects will be blocked by the water tank during driving to protect the oil control valve from damage. In addition, the oil control valve is located inside the outer edge of the frame, so when the vehicle falls over, in addition to being protected by the frame, its compact configuration does not affect the space for the rider's feet in the front half. On the other hand, since the oil control valve and the spark plug are located on the same side of the central symmetry line of the vehicle, in addition to making the variable valve lift system compact in the direction of the front wheel axle of the vehicle, it can also simplify maintenance.

[0014] The above summary and the following detailed description are exemplary in nature and are intended to further illustrate the scope of the patent application of the present utility model. Other purposes and advantages of the present utility model will be described in the subsequent specific implementation methods and drawings. BRIEF DESCRIPTION OF THE DRAWINGS
