Description
Technical field
The present invention relates to a kind of wheel system of vehicle engine.
Background technique
Motor car engine front-end face arranges some annexes usually, and described annex comprises water pump, power steering pump, air-conditioning, alternator etc.Described annex is provided with annex belt wheel, the bent axle in motor head face is also provided with crankshaft pulley.Described annex belt wheel and crankshaft pulley are connected by belt usually, and described belt is annular, wriggles and installs around in described crankshaft pulley and annex belt wheel, the motivational drive that annex belt wheel is exported by crankshaft pulley, and then drives operate accessories.Because motor head space of planes is limited, then a crankshaft pulley proposes high requirement by the design of moving towards of design to belt of an all annex of belt drives, adds the design difficulty of train.
For described defect, No. 201110229890th, Chinese patent application, propose new design in the patent application of " a kind of automobile engine front end accessory gear system " by name, it arranges two accessory belt, each belt is driven by crankshaft pulley, drives corresponding annex respectively.But this design still depends on the Direct driver of bent axle to annex belt wheel, each belt still needs by crankshaft pulley Direct driver, 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, disclose the crankshaft pulley of engine wheel system by the first belt drives Water-pump belt wheel in the patent application of " a kind of Novel belt drive wheel train " by name, Water-pump belt wheel is by the second belt drives power steering pump belt wheel of elastic belt material.Elastic belt limits due to himself material behavior, and load capacity is less, can not drive more belt pulley.In the prior art, the second belt is load power steering pump belt wheel only, therefore train design more cannot be simplified by second belt; Secondly, elastic belt when mounted, by himself elasticity and is extended by instrument and is mounted to belt wheel, need in installation process to overcome belt flexibility, stretched, installing force comparatively greatly, increase installation difficulty; 3rd, elastic belt is not by stretcher tensioning, usually idle pulley is not had to coordinate yet, and then the coated scope of belt be belt connect belt wheel the region that covers of outermost tangent line, if an elastic belt drives more belt wheel, then belt coverage area is comparatively large, and part that is easy and motor produces interferes, and adds the design difficulty of whole train; 4th, elastic belt only realizes tensioning according to the elasticity of himself, change when can not operate according to system and corresponding change belt tension; 5th, elastic belt is not because arrange stretcher, easily tension decay is there is after using a period of time, and then tension force declines, occur for avoiding this situation, when initially installing, belt initial tension is higher, and in addition, elastic belt easily produces shake in operation process, in order to reduce elastic belt shake, by increasing the installation tension of elastic belt to increase belt tension, but the increase of installation tension easily causes the radial force suffered by train to increase, and then shorten the working life of train, and the cost of the elastic belt of higher installation tension is higher.
To sum up, necessaryly a kind of new wheel system of vehicle engine is provided.
