Description
Technical field
The utility model belongs to technical field of automobile engine, is specifically related to a kind of dual-idle gear motor front-end wheel system.
Background technique
Motor front-end wheel system generally adopts crank pulley drive fan belt pulley, generator pulley and water pump pulley, and in the end fiber spans arranges automatic tensioner belt is compressed.
In the design of various trains, generally do not advise, in the first fiber spans (crank pulley is to fan pulley), idle pulley and Idle wheel are set, because the belt tension of this section is maximum, idle pulley is set or Idle wheel will cause that the load of idler support is larger at this section, the radial load of idle pulley or tension wheel shaft bearing is also maximum.
But apply to the fields such as engineering machinery during when motor, blower pulley is all higher with respect to the height of crankshaft center, belt span is larger, idle pulley need to be set and prevent belt shake.Meanwhile, in some motor, owing to being subject to the restriction of its inherent structure, the arrangement space of front end wheel train is very limited, in order to prevent belt and peripheral structure interference, also needs to change with idle pulley the trend of belt.Now just relate to the problem of the stressed bigger than normal and idle pulley bearing life of idler support.
Summary of the invention
The purpose of this utility model is to provide a kind of dual-idle gear motor front-end wheel system for the problems referred to above, can effectively disperse, reduce the stress of idler support, reduces the radial load of idle pulley bearing, the life-span of larger raising bearing.
The technical solution of the utility model: dual-idle gear motor front-end wheel system of the present utility model comprises vibration damper belt pulley, blower pulley, generator pulley, water pump pulley, and vibration damper belt pulley is anchored on crankshaft front end face; Blower pulley is anchored on wheel hub, wheel hub fastening is in engine cylinder cover front-end face, fan pulley center is 475mm~500mm with respect to crankshaft center height, generator pulley is anchored on engine cylinder body heat side by generator stand, water pump pulley is anchored on engine cylinder body heat side by water pump seat, each belt pulley connects by poly Vbelt, the dual-idle gear structure that the first idle pulley, the second idle pulley are established in the poly Vbelt of first paragraph span outside between vibration damper belt pulley and blower pulley; Between blower pulley and generator pulley, the 3rd idle pulley is established in second segment span poly Vbelt outside; Automatic tensioner is established in last fiber spans poly Vbelt outside between vibration damper belt pulley and water pump pulley, and the mounting bracket of automatic tensioner is anchored on engine cylinder-body front-end face.
The first described idle pulley, the middle part that the second idle pulley is arranged in span, the first idle pulley, the second idle pulley are longitudinally installed highly up and down side by side along bent axle, and its axle center is identical with the horizontal coordinate of bent axle.
Described the first idle pulley, the second idle pulley is arranged on same dual-idle gear support, dual-idle gear support is fixed on engine cylinder-body front-end face, the outer surface spacing 6mm of the first idle pulley and the second idle pulley, the first idle pulley is identical with structure, the diameter of the second idle pulley, diameter 74mm, idle pulley is inner is double row bearing support.
Advantage of the present utility model: the utility model arranges that the mode of idle pulley adopts 2 idle pulleys to support the belt of the first fiber spans.The carrying position of idler support is 2 fastening point at a distance of 79.5mm.Maximum radial load can reduce by 26.5%, more than maximum radial load can reduce 1000N.The utility model arranges that 2 idle pulleys prevent belt shake and space interference.The stress of idler support can effectively be disperseed, be reduced to this layout, adopts 2 idle pulleys to bear equal load simultaneously, and the life-span of idle pulley bearing is also corresponding obtains larger raising.The reliability of whole front end wheel train also obtains larger raising.
