Abstract
The utility model relates to an accessory drive structure of an automobile motor front end wheel system, in particular to a drive mechanism of a water pump pulley of an engine front end wheel system. The drive mechanism comprises a motor, a telescopic boom and a belt wheel, wherein one end of the telescopic boom is connected with the motor, and is controlled to move by the motor, and the belt wheel is arranged on the other end of the telescopic boom; and the belt wheel is arranged between a crankshaft belt wheel and an accessory belt wheel of the motor, and is in the state of being in synchronous contact or cutting off with the crankshaft belt wheel and the accessory belt wheel under the drive of the telescopic boom. By adopting the structure, when an accessory is not needed to work, the drive structure is cut off, the accuracy stops working, and the effect of maximally reducing oil consumption can be achieved.
Description
Technical field
The utility model relates to motor car engine front end train accessory drive structure, particularly relates to the driving mechanism of motor head train water pump pulley.
Background technique
Existing motor head train annex all is to be rotated through belt driven accessory by crank pulley; Power and moment of torsion are delivered in the front end train annex, and belt tension generally adopts the automatic tensioner tensioning or regulates that certain component belt pulley comes tightening belt in the front end train.Crank pulley 1 as shown in Figure 1 drives water pump pulley 2 and compressor pulley 3 runnings through belt 5 under the tensioning of Idle wheel 4, power and moment of torsion are delivered to water pump pulley 2 and compressor pulley 3.This kind front end train driving structure is simple, and cost is lower, and reliable performance is a kind of more rational driving structure.But when adopting this kind driving structure, the rotation that each annex can not stop with bent axle always is not when certain annex needs work; When just having started like motor; Engine water temperature is lower, and water pump pulley does not need rotation, but water pump pulley 2 still can be with crank pulley 1 rotation under the driving of belt 5; Can cause energy loss, increase oil consumption.
Summary of the invention
The purpose of the utility model provides a kind of front end train accessory drive mechanism and train whether annex and crank pulley are connected of can coming as required to confirm automatically; When the needs annex is worked; The work of driving mechanism coupling; When annex did not need work, driving mechanism broke off, and annex quits work.This front end train accessory drive mechanism can reach the effect that reduces engine consumption.
The technological scheme of the utility model is following:
A kind of motor head train accessory drive mechanism is made up of motor, telescopic boom and belt pulley.Wherein telescopic boom one end is connected with motor, is moved by Electric Machine Control, and the other end is equipped with belt pulley.Said belt pulley is arranged between the crank pulley and accessory belt pulley of motor, under the drive of telescopic boom, is in crank pulley and contacts simultaneously or off state with accessory belt pulley.
Wherein, motor is connected with tooth-strip part on the telescopic boom through driving gear, and the clockwise and anticlockwise drive telescopic boom through motor moves forward and backward.
A kind of motor head train that is furnished with above-mentioned accessory drive mechanism, it comprises crank pulley, belt, Idle wheel, accessory belt pulley and compressor pulley.Said crank pulley is connected through belt with compressor pulley, and carries out tensioning in that Idle wheel is set; And above-mentioned accessory drive mechanism is set between crank pulley and accessory belt pulley; The belt pulley of said accessory drive mechanism is arranged between crank pulley and the accessory belt pulley; Under the drive of telescopic boom, be in crank pulley and contact simultaneously or off state with accessory belt pulley.
In the utility model, motor is the controlling component whether whole driving structure connects crank pulley and accessory belt pulley, when motor rotates; The drive telescopic boom moves, and telescopic boom drives belt and moves, when belt pulley moves between crank pulley and the accessory belt pulley; Under the transmission of belt pulley, accessory belt pulley work is when belt pulley during away from crank pulley; Belt pulley and crank pulley and accessory belt pulley break off, and annex quits work, and can reach the effect that at utmost reduces oil consumption.
Description of drawings
Fig. 1 is the composition schematic representation of the frontal attachments driving structure of existing technology;
Fig. 2 is the schematic representation of the accessory drive mechanism of the utility model proposition;
Fig. 3 is the schematic representation of accessory drive mechanism when coupling is worked that the utility model proposes
Fig. 4 is accessory drive mechanism that the utility model the proposes schematic representation when breaking off annex and not working.
Embodiment
Further specify the structure of the utility model below in conjunction with accompanying drawing:
The accessory drive mechanism of the utility model design by output terminal the stepper motor of motor gear 6 is housed, the telescopic boom 7 and the belt pulley 8 of band tooth-strip part formed, and be as shown in Figure 2.Motor gear 6 is by step motor drive, and stepper motor is accepted the signal of ECU, when stepper motor receives the ECU signal; Motor gear 6 can clockwise or be rotated counterclockwise; Thereby the telescopic boom 7 that drives the band tooth-strip part moves up or down, and belt pulley 8 is flat tyre wheels, is fixed in by pin 9 on the telescopic boom 7 of band tooth-strip part; So the telescopic boom 7 of belt pulley 8 tooth-strip parts going along with is motion up or down together; Simultaneously, belt pulley 8 can be around pin 9 rotation of himself, thus with the transmission of power on the crank pulley 1 to water pump pulley 2.
Referring to Fig. 3 and Fig. 4, change than existing structure on the layout, it comprises crank pulley 1, belt 5, water pump pulley 2, compressor pulley 3 and accessory drive mechanism.Crank pulley 1 is connected through belt 5 with compressor pulley 3.And above-mentioned accessory drive mechanism is set between crank pulley 1 and water pump pulley 2; Just need belt be set; The belt pulley 8 of accessory drive mechanism is arranged between crank pulley 1 and the water pump pulley 2; Under the drive of telescopic boom 7, be in crank pulley 1 and contact simultaneously or off state with water pump pulley 2.
Front end train accessory drive arrangement works process is following:
When water pump pulley 2 needed work, ECU transmitted signal to stepper motor, and stepper motor drives motor gear 6 and is rotated counterclockwise; Motor gear 6 drives rack arm 7 and moves up, and because of belt pulley 8 and rack arm 7 connect together, belt pulley 8 moves up with rack arm; Belt pulley 8 contacts with crank pulley 1 with water pump pulley 2; When crank pulley 1 rotated, under the effect of contact friction force, crank pulley 1 drove belt pulley 8 and rotates together; Belt pulley 8 drive water pump pulleies 2 rotate together simultaneously, thereby power, the moment of torsion of crank pulley 1 is delivered on the water pump pulley 2.
When water pump pulley 2 did not need work, ECU gave the stepper motor signal, and stepper motor drives motor gear 6 and turns clockwise together; Rack arm 7 moves downward under the drive of motor gear 6, and belt pulley 8 leaves crank pulley 1 and water pump pulley 2, because of belt pulley 8 no longer contacts with crank pulley 1 and water pump pulley 2; So; During crank pulley 1 rotation, belt pulley 8 no longer rotates with water pump pulley 2, and water pump pulley 2 is not worked; Thereby the drawback that can avoid the tradition band accessory belt pulley that transmission brought always to turn round with crank pulley can connect and breaks off crank pulley and water pump pulley according to actual conditions at any time.
