Abstract
The utility model relates to a timing transmission mechanism provided with a variable valve timing controller and used for a gasoline engine. The timing transmission mechanism comprises an exhaust side camshaft belt pulley, an intake side belt pulley, a crankshaft timing belt pulley, an oil pump driving wheel, an idle wheel, a timing belt tensioning mechanism and a timing belt, wherein the exhaust side camshaft belt pulley and the intake side belt pulley are positioned at the upper part of the timing transmission mechanism, the crankshaft timing belt pulley and the oil pump driving wheel are positioned at the lower part of the timing transmission mechanism, and the idler wheel is positioned between the exhaust side camshaft belt pulley and the oil pump driving wheel; the timing transmission mechanism is characterized in that the intake side belt pulley is a belt pulley for the variable valve timing controller; and the timing belt tensioning mechanism comprises a mechanical tension wheel and a bracket, wherein the mechanical tension wheel is arranged on the bracket. The torque of the whole timing transmission mechanism can be effectively increased through the variable valve timing controller on the intake side, and the oil consumption can be reduced; and the mechanical tension wheel in the timing belt tensioning mechanism is selected for replacing the hydraulic tensioner, so that the cost of the whole timing transmission mechanism can be reduced to a certain extent.
Description
Technical field
The utility model belongs to the distribution device technical field of internal-combustion engine, is specifically related to the timing driving mechanism of 2.0L Dual Over Head Camshaft, 16 valve Gasoline Engine.
Background technique
Petrol engine can be divided into several different kinds of drive of gear type transmission, chain type transmission and belt type transmission by bent axle to the kind of drive of camshaft.At present, along with the development of technology and the progress of society, the belt type transmission of extensively adopting at present can not have been satisfied the demand of Consumer to the low oil consumption of high power gradually, and how to improve substantially on the original basis becomes the research and development emphasis of each motor producer at present.
Summary of the invention
For performance farthest has the potentiality of belt transmission engine product now, promote output power and output torque, reduce oil consumption, being chosen in increases the Variable Valve Time regulator on the basis of original engine timing transmission system, the utility model provides a kind of petrolic timing driving mechanism with Variable Valve Time regulator.
Concrete structure design proposal of the present utility model is as follows:
Petrolic timing driving mechanism with Variable Valve Time regulator, comprise exhaust side cams shaft pulley, air inlet side belt pulley, bent axle Timing Belt wheel, oil pump driving wheel, idle pulley, timing belt tensioning mechanism and Timing Belt, exhaust side cams shaft pulley and air inlet side belt pulley are positioned at top, bent axle Timing Belt wheel and oil pump driving wheel are positioned at the bottom, the middle part of idle pulley between exhaust side cams shaft pulley and oil pump driving wheel, described air inlet side belt pulley is a Variable Valve Time regulator belt wheel; Described timing belt tensioning mechanism is made up of mechanical type Idle wheel and support, and the mechanical type Idle wheel is located on the support; The pitch of described exhaust side cams shaft pulley is 8mm, and the number of teeth is 48, adopt arc toothed, intensity enhancing, better with the engagement of belt.
The utility model patent adopts single-stage belt transmission arrangement, driving machine oil pump simultaneously, selected the Variable Valve Time regulator that is applicable to belt for use, can effectively improve the moment of torsion of complete machine, reduced oil consumption by the Variable Valve Time regulator (VVT) of air inlet side.Owing to adopted the Variable Valve Time regulator (VVT) of air inlet side, do not needed complete machine is done too much change.The belt prop is selected the adjustable structure of mechanical type for use, replaces hydraulic tensioner with the mechanical tensioning wheel, also can reduce the complete machine cost to a certain extent.
