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 fixed-lock engine is assembled on the frame, including a crankcase, a cylinder, 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 speed change system to transmit power output. The water tank is assembled on the frame and is located in front of the fixed-lock engine. Among them, when observed from the side of the vehicle, the oil control valve is located below an upper edge of the frame, a first vertical line of the front edge of the water tank, a second vertical line of an axis of the crankshaft, and an area above a connecting line between the axis of the crankshaft and the axis of the transmission shaft.

[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, when viewed from the side of the vehicle, a center line of the oil control valve may be substantially parallel to a cylinder center line of the cylinder.

[0009] In the above-mentioned vehicle with a solid-lock engine, when viewed from the side of the vehicle, the oil control valve may overlap with a portion of the cylinder head.

[0010] The vehicle may be a one-speed accessible motorcycle.

[0011] The above-mentioned fixed-lock engine can be a single-cylinder engine.

[0012] Through the above design, since the oil control valve is located above the connecting line between the axis of the crankshaft and the axis of the transmission shaft, the oil control valve can be close to the fixed-lock engine to facilitate the control of oil pressure, and naturally make the configuration of the variable valve lift system compact. In addition, the oil control valve is also located behind the first vertical line of the front edge of the water tank, so foreign objects during travel will be blocked by the water tank for protection, preventing the oil control valve from being damaged by foreign objects. On the other hand, because the oil control valve is below the upper edge of the frame, in addition to being protected by the frame when the vehicle tipped over, its compact configuration does not affect the use space for the rider's legs in the front half.

[0013] 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

[0054] See also Figures 2 to 6 , which are respectively a side view of a vehicle with a fixed-lock engine, a partial side view of the fixed-lock engine, a cross-sectional view of the fixed-lock engine, a stereoscopic view of the fixed-lock engine, and a partially exploded view of the fixed-lock engine of a preferred embodiment of the utility model. The figure shows a vehicle 10 with a fixed-lock engine, which is a one-speed motorcycle in this embodiment, and mainly includes a frame 1, a fixed-lock engine 2, a water tank 3, a continuously variable transmission system 4, a front wheel 7, and a rear wheel 8. Figure 2 As shown, the vehicle frame 1 has an upper edge F, the fixed engine 2 is a single-cylinder engine, and is assembled with a water tank 3 on the vehicle frame 1, wherein a first vertical line R1 can be drawn along the front edge of the water tank 3 perpendicular to the direction of vehicle travel, and the water tank 3 is located in front of the fixed engine 2.

[0055] Please also read Figures 2 to 6 The solid-lock engine 2 includes a crankcase 20, a cylinder 21, a cylinder head 22, a variable valve lift system 23, a crankshaft 24, and a transmission shaft 25. In this embodiment, the cylinder 21 has a cylinder centerline C2, the variable valve lift system 23 is disposed on the cylinder head 22, the crankshaft 24 is accommodated in the crankcase 20 and has an axis C and a second vertical line R2 passing through the axis C, the transmission shaft 25 has an axis T and the axis T of the transmission shaft 25 and the axis C of the crankshaft 24 are connected to form a connecting line L. Among them, the variable valve lift system 23 includes a camshaft assembly 231, an intake rocker arm group 232, a valve group 233, a rocker arm shaft 234 and an oil control valve 235. The oil control valve 235 has a center line C1. The intake rocker arm group 232 is pivoted on the rocker arm shaft 234, including a first rocker arm 2321, a second rocker arm 2322 and a connecting mechanism 2323. The connecting mechanism 2323 is controlled by the oil circuit of the oil control valve 235 to connect or disconnect the first rocker arm 2321 and the second rocker arm 2322 to switch the power characteristics of the fixed lock engine 2, and connect the crankshaft 24 and the transmission shaft 25 via the stepless transmission system 4 to transmit power output to the rear wheel 8.

[0056] Back to Figure 2As shown, in this embodiment, when viewed from the side of the vehicle 10, the oil control valve 235 is located below the upper edge F of the frame 1, in the area above the first vertical line R1 of the front edge of the water tank 3, the second vertical line R2 of the axis C of the crankshaft 24, and the line L connecting the axis C of the crankshaft 24 and the axis T of the transmission shaft 25. Figure 3 As shown, in this embodiment, when viewed from the side of the vehicle 10 , the center line C1 of the oil control valve 235 is substantially parallel to the cylinder center line C2 of the cylinder 21 , and the oil control valve 235 partially overlaps with the cylinder head 22 .

[0057] Through the above design, since the oil control valve 235 is located above the line L connecting the axis C of the crankshaft 24 and the axis T of the transmission shaft 25, the oil control valve 235 can be close to the fixed-lock engine 2 to facilitate the control of the oil pressure, and naturally make the configuration of the variable valve lift system 23 compact. In addition, the oil control valve 235 is also located behind the first vertical line R1 of the front edge of the water tank 3, so foreign objects during travel will be blocked by the water tank 3 for protection, preventing the oil control valve 235 from being damaged by foreign objects. On the other hand, because the oil control valve 235 is below the upper edge F of the frame, when the vehicle 10 falls over, in addition to being protected by the frame 1, its compact configuration does not affect the use space for the front half of the rider's legs.

[0058] The above embodiments are merely examples for the convenience of explanation. The scope of rights claimed by the present utility model shall be based on the scope of protection required by the patent application documents, and is not limited to the above embodiments.
