Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technological scheme in the embodiment of the present invention is clearly and completely described.
As shown in Figure 1 or 2, be the specific embodiment of engine accessory gear train mechanism of the present invention.Comprising the first belt drive unit and the second belt drive unit that connect the same power source, described belt drive unit comprises the first shock-proof crank pulley 1, automatic tension belt wheel 3, alternator belt wheel 5 and the air conditioner compressor belt pulley 6 that are wrapped over by the first multi-rib-belt 7; Described second belt drive unit comprises the second shock-proof crank pulley 2, the mechanical-hydraulic power-assisted steering pump belt wheel 8 that are wrapped over by the second multi-rib-belt 9.
A kind of engine accessory gear train mechanism that the embodiment of the present invention provides, according to foregoing, because the first belt drive unit is connected the same power source with the second belt drive unit, therefore the first belt drive unit and the second belt drive unit can independently work simultaneously, wherein the second belt drive unit can provide power source by mechanical-hydraulic power-assisted steering pump to steering system, thered is provided by electronic power assist steering system when the power source of steering system upgrades to, can directly cancel the second belt drive unit, can be the upgrading of car load configuration and the reserved layout design scheme improved of change like this, on the first belt drive unit impact less (can not need to redesign the first belt drive unit), and then it is smaller on the layout impact of engine accessory system, can find out that the engine accessory system in the embodiment of the present invention can take into account mechanical-hydraulic steering system and electronic power assist steering system preferably, this engine accessory system can be made to be applied in different cars preferably fasten, versatility is better.
When steering system adopts electronics force aid system, after cancelling the second belt drive unit, unaffected to the usability of complete machine, and can avoid providing by mechanical-hydraulic steering boost system the mechanical loss produced during power source, promote the useful horsepower of complete machine preferably.
Because the versatility of engine accessory system is relatively good, can special purpose parts be developed, shorten the construction cycle and can development cost be reduced.
First shock-proof crank pulley 1 described in the embodiment of the present invention is connected along coaxial rigid with described second shock-proof crank pulley 2, because described first shock-proof crank pulley is connected the same power source with described second shock-proof crank pulley, therefore power source can input from the first shock-proof crank pulley 1 and the second shock-proof crank pulley 2 simultaneously, and then the first multi-rib-belt 7 motion and the second multi-rib-belt 9 can be driven to move simultaneously.
Alternatively, described first multi-rib-belt 7 and described second multi-rib-belt 9 can be all six wedge belts, and accordingly, the belt wheel that described first multi-rib-belt 7 and described second multi-rib-belt 9 are wrapped over is six wedge groove belt wheels.This is because six wedge groove belt wheels are conventional belt wheel, can avoid redesigning, and also can reduce user cost preferably.
Preferably, described second multi-rib-belt 9 is elasticity multi-rib-belt, and can make without the need to increasing belt tension mechanism like this, be the layout relative compact of gear mechanism, and can avoid carrying out regular tensioner maintenance; Can also transmit from tensioner performance the moment of rotation applied by the second shock-proof crank pulley 2 by elasticity multi-rib-belt in addition, and then driving device hydraulic power-assisted steering pump normally works, and provide power-assisted steering power source to car load steering system.
Wherein, described first shock-proof crank pulley 1, described automatic tension belt wheel 3, alternator belt wheel 5 and air conditioner compressor belt pulley 6 is provided with inside the train of described first belt drive unit; Be provided with transition pulley 4 outside the train of described first belt drive unit, the belt wheel being positioned at transition pulley 4 both sides can be made like this to have larger cornerite, avoid the first multi-rib-belt 7 is skidded, meet requirement of system design.
The above-mentioned transition pulley 4 mentioned can be flat wheel, can increase the cornerite of the belt wheel being positioned at transition pulley 4 both sides so further, avoids the first multi-rib-belt 7 to occur the phenomenon of skidding better.
Conveniently understand, the exploitation of engine accessory gear train mechanism generally includes following four steps:
First step: collect accessory wheel system each component relevant parameter (pulley diameters, each parts turn inertia, power consumpiton etc.);
Second step: according to the relevant parameter collected, calculated by train static arrangement, determines train central plane coordinate position and drivign belt Len req and static system tension force;
Third step: utilize special-purpose software, by train dynamic analog calcutation, determines the requirement of train alignment degree, each belt wheel radial load, dynamic tension demand and system eigentone etc. needed for system;
4th step: according to result of calculation, makes each train exemplar, then carries out matching test, selects the belt, belt tightener etc. of the most applicable system tension needs.
In conjunction with each belt wheel parameter of the first scheme in foregoing and accompanying drawing 3, and composition graphs 1, the train of described first belt drive unit can be wrapped over described first shock-proof crank pulley 1, described automatic tension belt wheel 3, described transition pulley 4, alternator belt wheel 5 and air conditioner compressor belt pulley 6 successively.
Each belt wheel parameter of first scheme in 3 with reference to the accompanying drawings, and composition graphs 2, the train of described first belt drive unit can be wrapped over described first shock-proof crank pulley 1, described automatic tension belt wheel 3, alternator belt wheel 5, described transition pulley 4 and air conditioner compressor belt pulley 6 successively.
In Fig. 3, each belt wheel parameter is for illustrating, therefore the first belt drive unit does not limit to and above-mentioned two schemes yet, the parameter value of each belt wheel needs to combine actual situation setting, and then the first belt drive unit can also be made to have other layout.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
