Description
Technical field
The present invention relates to a kind of vehicular engine train.
Background technique
Motor car engine front-end face arranges some annexes conventionally, and described annex comprises water pump, power steering pump, air-conditioning, alternator etc.Annex belt wheel is installed on described annex, on the bent axle of motor head face, is also provided with crankshaft pulley.Described annex belt wheel and crankshaft pulley connect by belt conventionally, and described belt is annular, and wriggle and install around on described crankshaft pulley and annex belt wheel, the motivational drive that annex belt wheel is exported by crankshaft pulley, and then drive annex work.Because motor head space of planes is limited, crankshaft pulley proposes high requirement by the design of all annexes of belt drives to the design of moving towards of belt, has increased the design difficulty of train.
For described defect, No. 201110229890th, Chinese patent application, proposes new design in the patent application of " a kind of automobile engine front end accessory gear system " by name, and it arranges two accessory belt, each belt is driven by crankshaft pulley, drives respectively corresponding annex.But this design still depends on the direct driving of bent axle to annex belt wheel, and each belt still needs directly to drive by crankshaft pulley, therefore whole train and belt to move towards design still limited, the design difficulty of train and belt is still higher.
For described defect, No. 200820095897th, Chinese patent application, in the patent application of " a kind of Novel belt drive wheel train " by name, disclosed the crankshaft pulley of engine wheel system by the first belt drives Water-pump belt wheel, Water-pump belt wheel is by the second belt drives power steering pump belt wheel of elastic belt material.Elastic belt is due to himself material behavior restriction, and load capacity is less, can not drive more belt pulley.In the prior art, the second belt is power steering pump belt wheel of load only, therefore cannot train design more be simplified by second belt; Secondly, elastic belt when mounted, by the elasticity of himself and by instrument, its extension is mounted to belt wheel, needs to overcome belt elasticity in installation process, is stretched, and installing force is larger, increase installation difficulty; The 3rd, elastic belt is not by stretcher tensioning, conventionally do not have idle pulley to coordinate yet, and then the coated scope of belt is the region that the outermost tangent line of belt wheel that belt connects covers, if an elastic belt drives more belt wheel, belt coverage area is larger, and part easy and motor produces interferes, and has increased the design difficulty of whole train; The 4th, elastic belt is only realized tensioning according to the elasticity of himself, the variation in the time of can not turning round according to system and corresponding change belt tension; The 5th, elastic belt is not because arrange stretcher, after using a period of time, easily there is tension force decay, and then tension force declines, for avoiding this situation to occur, when initial installation, belt initial tension is higher, and in addition, elastic belt easily produces shake in operation process, in order to reduce elastic belt shake, the installation tension that can pass through to increase elastic belt is to increase belt tension, yet the increase of installation tension easily causes the suffered radial force of train to increase, and then the working life of shortening train, and the cost of the elastic belt of higher installation tension is higher.
To sum up, necessaryly provide a kind of new vehicular engine train.
