Abstract
The utility model relates to a belt drive system for engine accessories of an automobile, which comprises a crank shaft belt wheel, an air conditioner compressor belt wheel, a water pump belt wheel, an alternating current generator belt wheel, an idler wheel, a mechanical power steering pump belt wheel and a first polywedge belt. The belt drive system is characterized in that the crank shaft belt wheel is a double-layered belt wheel. The first polywedge belt is an elastic polywedge belt. A second elastic polywedge belt is arranged; one layer of the crank shaft belt wheel, the air conditioner compressor belt wheel, the water pump belt wheel, the alternating current generator belt wheel and the idler wheel are tightly wound by the first polywedge belt in sequence; and the other layer of the crank shaft belt wheel and the mechanical power steering pump belt wheel are tightly wound by the second polywedge belt. Because the belt wheels of the accessories are driven by applying the elastic polywedge belt, a tightening device is reduced on the premise of satisfying the performance requirements of accessory systems, so that not only the structure of the engine is compact, but also the cost of the engine is reduced. The mechanical power steering pump is driven by adopting an independent elastic polywedge belt, so as to facilitate the entire automobile to switch the electronic mechanical power steering pump.
Description
Technical field
The utility model relates to a kind of motor, relates to a kind of motor car engine accessory belt drive system in particular.
Background technique
The drivign belt of conventional motor car engine accessory belt drive system is common poly Vbelt, and the tension force that need add the generation of automatic or manual stretcher comes belt is implemented tensioning.Deficiency is that engine structure is compact inadequately, performance is stable inadequately, but also has increased cost, and is all influential to noise, vibrations and the intensity of accessory system, thereby influences the comfort level of car load.At present, electronic power assist steering configuration is used by numerous automobile production producer now.The power resources of electronic power assist steering system are in the electronic power assist steering pump, if applying electronic power-assisted steering pump needs the machine power steering pump is removed naturally.And the engine accessory power rating belt drive system is in the conventional design exploitation, machine power steering pump belt wheel often is not to come driven with a belt separately, be driven but reinstate a belt, do not consider car load demand coupling electronic power assist steering system with the belt wheel one of other annex.If the car load demand need be switched the electronic power assist steering pump, will redesign exploitation to existing engine accessory system, like this, will bring a series of trouble.
Summary of the invention
The purpose of this utility model is to provide a kind of motor car engine accessory belt drive system, is solving engine structure is compact inadequately, performance is stable inadequately technical problem simultaneously, considers convenient, fast when car load need switch the electronic power assist steering pump.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of motor car engine accessory belt drive system comprises crankshaft pulley, air condition compressor belt wheel, Water-pump belt wheel, alternator belt wheel, idle pulley, machine power steering pump belt wheel and first poly Vbelt.It is characterized in that: described crankshaft pulley is double-deck belt wheel.Described first poly Vbelt is an elastic poly V-belt.And flexible second poly Vbelt is set; Described first poly Vbelt takes up described crankshaft pulley one deck, air condition compressor belt wheel, Water-pump belt wheel, alternator belt wheel and idle pulley successively; Described second poly Vbelt takes up crankshaft pulley another layer and machine power steering pump belt wheel.
Described air condition compressor belt wheel, alternator belt wheel are arranged in the crankshaft pulley both sides, and described Water-pump belt wheel is arranged in the crankshaft pulley top; Described machine power steering pump belt wheel and alternator belt wheel are arranged in the crankshaft pulley homonymy.
Described idle pulley is arranged in the middle of the described accessory belt drive system.
Good effect of the present utility model: come each annex belt wheel is driven owing to use elastic poly V-belt, like this, under the prerequisite that satisfies the accessory system performance requirement, reduced tensioning mechanism, not only make engine structure become compact, and the motor cost is reduced.Meanwhile, owing to lacked tensioning mechanism, can also further solve the long-standing noise of accessory system, vibrations etc. and have a strong impact on car load comfort level problem.Adopt independent elastic poly V-belt driving device power steering pump, make things convenient for car load to switch the electronic power assist steering pump, significantly reduced because of changing a series of trouble that accessory system brings.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
