Abstract

PURPOSE:To improve drive feeling by setting a muffler and an engine in a same vibration system by fixing the muffler onto the engine body mounted into a chassis, thus reducing the stress applied onto an exhaust pipe connected with the muffler and the engine, and softly supporting the engine. CONSTITUTION:In a golf car, an air-cooled type 4-cycle engine 8 is supported onto a swing frame 5 through the rubbers 23 fixed at the front and rear parts. An air cleaner 9 is installed onto the suction side of the engine 8, and a muffler 11 is installed onto the exhaust side through an exhaust pipe. In this case, the muffler 11 is fixed onto the engine 8 body through a stay 12. Further, the outside of the muffler 11 is covered with a cover 22 through a space, and said cover 22 allows the opened port 22a on the front side to communicate to the exhaust duct of the cover 19 of the engine 8, and an opened port 22b is formed onto the rear edge side. Therefore, the muffler 11 and the engine 8 can be set in a same vibration system, and a prescribed purpose can be achieved.

かかり、破損しやすくなっていた。Some golf cars are powered by an engine. In conventional engine-driven golf cars, a transmission for decelerating and transmitting power to the rear wheels is provided independently of the engine body, and a muffler is fixed on the case of this transmission. For this reason, the engine and muffler have different vibration systems, and since the exhaust pipe is connected between these different vibration systems, excessive stress is applied to the exhaust pipe, making it susceptible to damage.

また、ゴルフカーの乗心地を良好にするには、エンジン

A horizontal frame 4 is fixed to the intermediate part of the main body frame 1, and the front end of a swing frame 5.5 is pivotally supported on this horizontal frame 4, and the rear end is connected to the main body frame l via a shock absorber 6. It is elastically supported at the rear end.

る。An air-cooled four-stroke engine 8 is supported by the swing frames 5, 5 via rubbers 23, 23 fixed at the front and rear, respectively. An air purifier 9 is attached to the intake side of the engine 8, and a muffler 11 is attached to the exhaust side via an exhaust pipe 10. This muffler 11 is fixed to the main body of the engine 8 via a stay 12.

is attached, and a pulley 14 is attached to the other end. The pulley 14 connects to the transmigration chain 17 via the belt 15.
The power is transmitted to the input pulley 16 of the input pulley 16. Each of the above-mentioned devices is covered with a resin vehicle body cover 18.

るようにする。The engine 8 has an outer portion covered by a cover 19 through a space.
covered with. This cover 19 is connected to a cooling air intake duct 20 via the cooling fan 13 on one side, and has an exhaust duct 21 attached on the other side with the engine 8 in between. The cooling fan 13 forces the air sucked from the intake duct 20 into the space inside the cover 19 as cooling air, cools the engine 8, and then exhausts the engine 8 to the exhaust duct 21.

却される。Further, the outside of the muffler 11 is covered with a cover 22 with a space interposed therebetween. The cover 22 has an opening 22a provided at the front end communicating with the exhaust duct 21 of the cover 19, and an opening 22b provided at the rear end. Therefore, the cooling air exhausted from the exhaust duct 21 enters the cover 22 through the opening 22a, and is exhausted through the opening 22b at the rear end while forcing the air through the space. The muffler 11 is cooled by the cooling air passing through the cover 22.

上述したように、上記ゴルフカーでは、エンジン８の本
体に、ステー１２を介してマフラ１１が直接固定されて
