Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figures 2 to 5, comprise according to the concrete structure of the air compressor of the utility model embodiment: air compressor 1, air compressor gear 3 and the engaging and disengaging gear 2 be arranged between the air compressor crank 15 of air compressor 1 and air compressor gear 3.This engaging and disengaging gear 2 controls its clutch separation, engagement by automobile pressure feedback signal, clutch separation, conjugate control air compressor crank be separable with air compressor gear, engage, thus control air compressor working state, after gas made by gas holder, air pressure feedback signal solenoidoperated cluthes are separated, air compressor crank with engaging and disengaging gear stops the rotation, air compressor does not work, make this air compressor reduce complete-vehicle oil consumption, and there is low power consumption, low exhaust temperature, lowly alter the advantage such as oil mass, high reliability.
Specifically, as shown in Figures 2 and 3, the air compressor crank 15 of air compressor 1 is arranged in air compressor crankcase 12, air compressor 1 adopts water-cooled cylinder sleeve, cylinder sleeve and air compressor crankcase 12 cast solid, the material of air compressor crank 15 adopts 42CrMo, and carries out nitriding treatment.Air compressor crankcase 12 has filler opening 13, by oil inlet pipe, engine lubricating oil is transported in air compressor crankcase 12, by the crankshaft oil gallery 16 in air compressor crank 15, lubricant oil is transported to the movement parts such as the male splined shaft 18 of air compressor crank 15, lubrication movement parts.
Engaging and disengaging gear 2 comprises: air pressure control hole 21, engaging and disengaging gear housing 22 and clutch 23, wherein, engaging and disengaging gear housing 22 is fixedly installed to the front end of air compressor crankcase 12 by four the first bolts 14, clutch 23 is sleeved on the male splined shaft 18 of air compressor crank 15, can slide and realize separation, engagement capability.Air compressor gear 3 is fixedly installed on clutch 23 by six the second bolts 31, and air compressor gear 3 and air compressor crank 15 can realize relatively rotating.Engaging and disengaging gear 2 is installed between air compressor crank 15 and air compressor gear 3, controls air compressor 1 by engaging and disengaging gear 2 and rotate.The separation of clutch 23, engage and controlled by air pressure.Clutch 23 adopts disc spring chip architecture, air pressure controls, air pressure feedback signal is from vehicle reservation tank: when gas holder air pressure is down to 0.7MPa, engaging and disengaging gear 2 engages, and engagement time is not more than 3s, when gas holder air pressure rises to 0.98MPa, engaging and disengaging gear 2 is separated, disengaging time (0.5 ~ 0.7) s, and clutch 23 safe mode is permanent magnet, normal engagement, does not allow lubricant oil to enter.
As shown in Figure 5, air pressure control hole 21 is communicated with automobile pressure signal feed back hole by tracheae, and air pressure control signal is from vehicle reservation pressure tank, and air compressor, according to vehicle reservation tank air pressure adjustment working state, realizes using gas work, quits work without gas.Air pressure solenoidoperated cluthes 23 are separated, and realize air compressor gear 3 and be separated with air compressor crank 15, air compressor gear 3 is rotated further with engine gear, and air compressor crank 15 stops the rotation, and air compressor 1 quits work.When gas holder air pressure is lower than setting limit value, clutch 22 engages, and air compressor crank 15 engages with air compressor gear 3, and air compressor gear 3 drives air compressor crank 15 to rotate, and namely air compressor 1 works, and the safe mode of clutch is that only engagement is not separated.
The front end of air compressor 1 has return opening 17, and engaging and disengaging gear housing 22 has return opening 25.The lubricant oil of air compressor crankcase 12 congregate flows into oil duct bottom engaging and disengaging gear housing 22 by the return opening 17 of air compressor front end, flow out from the return opening 25 of engaging and disengaging gear housing 22 again, get back to engine gear case, complete the turnover of air compressor 1 lubricant oil, guarantee oil return is unimpeded, avoids air compressor to alter oil.
As shown in Figure 4, engaging and disengaging gear 2 also has pressure compensation opening 24, and this pressure compensation opening 24 and engaging and disengaging gear housing 22 above both sides air flue are communicated with.Gas in air compressor crankcase 12 is discharged by pressure compensation opening 24, guarantees air compressor crankcase 12 inner chamber ventilating and cooling, reduces bent axle loading pressure, guarantees that oil return is unimpeded.Air pressure control hole 21 on engaging and disengaging gear housing 22, pressure compensation opening 24, return opening 25 are not connected, respectively have each passage, are sealed by seal ring.
Air compressor with engaging and disengaging gear is compared with existing air compressor, and when vehicle reservation tank air pressure reaches limit value (namely making gas), air pressure feedback signal is transported to clutch, clutch separation, air compressor crank is separated with air compressor gear, and air compressor gear continues to rotate with engine wheel system, air compressor crank stops the rotation, air compressor does not work, and air compressor power consumption, oil consumption are 0, therefore, reduce complete-vehicle oil consumption, especially few in expressway brake, gas consumption is few, fuel-efficient successful.After gas made by gas holder, the air compressor of band engaging and disengaging gear stops bent axle and stops the rotation, and air compressor does not work, and therefore, band engaging and disengaging gear air compressor advantage is low power consumption, low exhaust temperature, lowly alter oil mass, high reliability.
To sum up, this air compressor installs engaging and disengaging gear between air compressor crank and air compressor gear, and by the separation of automobile pressure feedback signal solenoidoperated cluthes, engagement, clutch separation, conjugate control air compressor crank be separable with air compressor gear, engage, thus control air compressor working state, after gas made by gas holder, air compressor with engaging and disengaging gear stops bent axle and stops the rotation, air compressor does not work, make this air compressor reduce complete-vehicle oil consumption, and there is low power consumption, low exhaust temperature, lowly alter the advantage such as oil mass, high reliability.
The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
