Abstract
A mounting structure of an engine transmission system comprises a chain transmission system and a gear transmission system, wherein the chain transmission system comprises a drive sprocket and a camshaft sprocket, the gear transmission system comprises a crankshaft gear, an intermediate gear and a pump-driving gear, the drive sprocket is rigidly connected with the pump-driving gear, the intermediate gear is rigidly connected with the pump-driving gear and the crankshaft gear, and the pump-driving gear is connected with an oil injection pump. The mounting structure of an engine transmission system is characterized in that the whole transmission system is arranged on the rear end of an engine. The transmission system of the utility model utilizes the advantage that the torsional vibration ofa crankshaft on the rear end of the engine is small and can combine the pump-driving gear with a camshaft driving gear in one piece, thereby the cost of the engine is reduced, the transmission systemis simplified, the distribution mechanism timing is more accurate, the operation of the chain system and the gear system are smoother and steadier, and the vibration noise of overall unit is reduced.
Description
Technical field
The utility model belongs to the technical field that motor is made, particularly a kind of mounting structure of engine driving system.
Background technique
At present, along with the continuous development of engine technology, the overhead camshaft technology relies on its light-weighted advantage to become the new technology that most of engine production producer is adopted.
The overhead camshaft technology is divided into Single Over Head Camshaft and Dual Over Head Camshaft technology, its common characteristic be with cam shaft arrangement on cylinder head, so, the reciprocation mass of distribution device is significantly less than OHV.But because cam shaft distal from crankshaft center, makes the timing driving mechanism comparatively complicated.The transmission system of motor was arranged in the front end of motor in the past, according to the size of transmission system actual transfer load, adopted chain drive system or gear train assembly.Because the torsional oscillation of motor head is bigger, and the accuracy of valve timing and the operation stability of gear and chain are had considerable influence; In addition, for the bigger pneumatics pump of driving torque, adopting an independent gear or independent set of gears usually is to drive, so both increase the volume and the quality of motor, also increased the cost of motor, simultaneously, because transmission system is complicated, increased the vibration noise of motor.
Summary of the invention
The utility model purpose provides a kind of mounting structure of engine driving system.
The technical solution of the utility model is achieved in that
A kind of mounting structure of engine driving system, transmission system comprises chain drive system and gear train assembly, described chain drive system comprises driving sprocket wheel, camshaft sprocket, described gear train assembly comprises crankshaft gear, intermediate gear and pump driver gear, driving sprocket wheel and pump driver gear are rigidly connected, intermediate gear and pump driver gear and crankshaft gear engagement, pump driver gear and pneumatics pump are rigidly connected, and it is characterized in that: whole drive system is installed in the rear end of motor.
Engine driving system of the present utility model is by utilizing the little advantage of motor rear end crankshaft torsional vibrations and pump driver gear and camshaft drive gear being unified, reduced the motor cost, simplified transmission system, make the distribution device timing more accurate, chain system and gear train operation are more steady, and the vibration noise of complete machine reduces.
