The design of the motion mode of above-mentioned belt transmission system can be revised driving belt 7 tension force automatically, guarantees the size of crankshaft pulley 1 and power-assisted steering pump belt wheel 3 cornerites.Because the self-characteristic of hydraulic auto-tensioner 23 has determined idle pulley 22 operating limit positions.In between the motor area of this idle pulley 22, driving belt 7 tension force, each v-belt contact angle size have all obtained effective control.
The installation steps of the belt transmission system of vehicle motor of the present utility model are described below in conjunction with Fig. 1.At first, with crankshaft pulley 1, power-assisted steering pump belt wheel 3, generator belt wheel 4, Water-pump belt wheel 5, air condition compressor belt wheel 6 fixed-site; Then, the rotating center 211 of tensioning frame 21 and the round end 231 of hydraulic auto-tensioner 23 are arranged on the engine body; At last, driving belt 7 is installed.
About the installation of driving belt 7, concrete steps are as follows: at first, automatic takeup 2 is fixed by the round end 231 of hydraulic auto-tensioner 23 and the rotating center 211 of tensioning frame 21; Then, with the driving belt 7 at crankshaft pulley 1, power-assisted steering pump belt wheel 3, generator belt wheel 4, Water-pump belt wheel 5, air condition compressor belt wheel 6 places around to arranging; Then, by auxiliary mould, the auxiliary mounting points 212 of rotation on the tensioning frame 21 when hydraulic auto-tensioner 23 is in compressive state, is in place the driving belt 7 at crankshaft pulley 1 and idle pulley 22 edges.Wherein, illustrated auxiliary mounting points 212 is used the hexagon head structure of standard, and auxiliary mould can directly adopt standard cartridges.
In sum, the belt transmission system of vehicle motor of the present utility model, key is the use of hydraulic auto-tensioner 23 and the layout of crankshaft pulley 1, power-assisted steering pump belt wheel 3, generator belt wheel 4, Water-pump belt wheel 5, air condition compressor belt wheel 6 and driving belt 7, and this structure and layout can make the tension force size of driving belt 7 be able to automatic adjusting; Prevent the appearance of problems such as driving belt 7 is shaken, skidded, noise; Guarantee each v-belt contact angle size.The use of hydraulic auto-tensioner 23 and mounting type can make the automatic control that is able to of belt tension size, are convenient to the train dismounting.That is the order of placement of the belt transmission system of vehicle motor of the present utility model and mutual alignment relation are novel.And because the existence of automatic takeup 2, the installation of entire belt transmission system, dismounting become simple and easy.
Those skilled in the art know easily; the above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.Protection domain of the present utility model is determined by claims.
