The specific embodiment
By describing technology contents of the present invention, structural attitude in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
A function of walking lamely back refers in the time of cannot starting when the power system et out of order of the drive motor of Series-Parallel HEV, utilizes driving engine to start by force the function that automobile is sailed back parking area.Adopt while walking lamely back field function, vehicle is equivalent to direct engage a gear starting, and can only advance and can not retreat, can damage power-transfer clutch, and be a kind of the function that could use under faulty condition at automobile.
Refer to Fig. 1, present embodiment is that field device is returned in a kind of limping for Series-Parallel HEV, comprises source of the gas assembly 10, oil pump assy 20 and clutch booster 30.
Source of the gas assembly 10 comprises that source of the gas 11, the first electromagnetic valve 12, the second electromagnetic valve 13 and the 3rd electromagnetic valve 14, the first electromagnetic valves 12 are two-position five-way type, and the second electromagnetic valve 13 is directly moving open type of bi-bit bi-pass, and the 3rd electromagnetic valve 14 is directly moving closed type of bi-bit bi-pass.Wherein, the first electromagnetic valve 12, the second electromagnetic valve 13 and the 3rd electromagnetic valve 14 shown in Fig. 1 is all in power-off valve position.
The first electromagnetic valve 12 comprises three imports and two outlets; When power-off valve position, the first import is communicated with by, the second import and the first outlet, and triple feed inlet and second exports and is communicated with; During electric valve position, the first import is communicated with the first outlet, the second import and second exports and is communicated with, triple feed inlet by.Wherein, the outlet that the first outlet is sealing.
The second electromagnetic valve 13 comprises an import and primary outlet; When power-off valve position, import and outlet are communicated with; When obtaining electric valve position, import is to outlet one-way conduction.The import of the second electromagnetic valve 13 is connected with the second outlet of the first electromagnetic valve 12.
The 3rd electromagnetic valve 14 comprises an import and primary outlet; When power-off valve position, outlet is to import one-way conduction; When obtaining electric valve position, import and outlet conducting.
Refer to Fig. 2, oil pump assy 20 comprises stretcher 21, many connecting rods 22 and hydraulic cylinder assembly 23, and hydraulic cylinder assembly 23 comprises oil cylinder 231, piston 232, piston rod 233 and oil outlet 234.Stretcher 21 is connected on piston rod 233 by many connecting rods 22, when stretcher 21 is operated, stretcher 21 promotes piston rod 233 to the interior movement of oil cylinder 231 by connecting rod 22, and piston rod 233 promotes piston 232 high pressure oil in oil cylinder 231 is outwards extruded by oil outlet 234.
Source of the gas 11 is connected with the second import of the first electromagnetic valve 12 with power-assisted admission port 332 respectively, and oil outlet 234 is connected with oil inlet 334, and the outlet of the second electromagnetic valve 13 is connected with admission port 331, and the import of the 3rd electromagnetic valve 14 is connected with power-assisted exhausr port 333.When the high pressure oil in oil pump assy 20 enters clutch booster from oil inlet 334, spool is promoted admission port 331 from path assembly 33 enclose insides by high pressure oil, and power-assisted admission port 332 or power-assisted air extractor duct 333 are communicated with cylinder 31.
When automobile is during in normal motoring condition, the second electromagnetic valve and the 3rd electromagnetic valve all keep off-position.When needs cut-off clutch carries out, to the first electromagnetic valve energising, the high pressure gas in source of the gas successively by promoting push rod after the first electromagnetic valve and the second electromagnetic valve from admission port enters the cylinder of clutch booster, and push rod promotes power-transfer clutch and makes its separation; When the closed power-transfer clutch of needs, to the first electromagnetic valve power-off, the first electromagnetic valve and source of the gas open circuit, and the high pressure gas in clutch booster are outside by discharging after the second electromagnetic valve and the first electromagnetic valve successively, the push rod that loses the propelling thrust of high pressure gas is retracted, and makes power-transfer clutch closed.
When automobile place et out of order need to adopt while walking lamely back function, to the first electromagnetic valve power-off, the first electromagnetic valve and source of the gas are opened circuit, the second electromagnetic valve energising is made to admission port sealing, to the 3rd electromagnetic valve energising, power-assisted exhausr port is communicated with outside.Step on stretcher, by oil pressure, the spool in path assembly is moved, when opening power-assisted admission port, seal power-assisted exhausr port, because source of the gas is directly communicated with power-assisted admission port, now the high pressure gas in source of the gas just can enter in cylinder and promote push rod from power-assisted admission port, make disengaging of clutch; Then start the engine; then with speed very slowly, unclamp stretcher; make power-assisted admission port slowly pent while power-assisted exhausr port be slowly opened; push rod is slowly retracted; and then make power-transfer clutch closed at leisure; finally make driving engine directly drive drive motor to drive vehicle wheel rotation by power-transfer clutch, start by force automobile.With respect to force start automobile in background technology, cause power-transfer clutch to be scrapped, this device can carry out by stretcher the closing speed of control clutch, the driving engine rotating is engaged with drive motor at leisure, the injury that power-transfer clutch is produced is dropped to minimum, guarantee that automobile can successfully leave back parking area and can not cast anchor in roadside.
Preferably, source of the gas 11 comprises gascollecting cap cylinder and auxiliary inflation pump.Auxiliary inflation pump can be assisted and inflate when the air pressure deficiency of gascollecting cap cylinder, guarantees that power-transfer clutch can be operated.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification sheets of the present invention and accompanying drawing content to do; or be directly or indirectly used in other correlative technology fields, be all in like manner included in scope of patent protection of the present invention.
