Abstract
An electrohydraulic combination control type clutch belongs to automotive parts technology field. It features shell respectively fitting with interval of annular gear, gear and disconnecting valve, annular gear engagement transmission with gear, a crescent block fixed in shell, said crescent block having hydraulic fluid chamber having disconnecting valve to form high-pressure oil cavity A and low-pressure oil cavity B respectively on outer two ends of crescent block, disconnecting valve pivot joint with electromagnet fixed in shell. Said invention has advantages of 1, reliable product performance, long service life and low cost, 2, low noises, small impulsion, long spare service life, 3, no pollution, 4, simple installing, making and processing.
Description
Technical field
The invention belongs to technical field of automobile components.
Background technique
In vehicle starting and when gearshift, the separation by friction plate between active part on the clutch (being connected) and the secondary part (being connected) with transmission input shaft with motor with combine the interruption and the transmission of realization engine output power.
At present, employed clutch on the automobile industry all is a friction clutcch.But there are a lot of defectives in this product, because product performance and reasons in structure, these defectives can't solve.Main performance the following aspects:
1) clutch is short working life
Because the friction clutcch that uses is to lean on the friction of driving and driven friction plate to come transferring power at present, in shift process, driving and driven friction disc wear is quite serious, causes the Acceptable life of friction plate to shorten.
2) impact is big, noise is big, reduce part life
In shift process, because vehicle inertia is big, cause the speed discrepancy of driving and driven friction plate big, combination rapidly after gearshift is finished produce big noise and impact, thereby the power train component can reduce greatly working life.
3) seriously polluted
Because contain poisonous asbestos product in the friction plate constouctional material, the asbestos dust that wears away flies in the air, people and ecotope are produced bigger pollution.
4) job insecurity
Because after the clutch separation again cohesive process produce big unit friction work, produce big calorimetric and can not in time shed, the lighter makes the clutch distortion, causes the friction plate area of contact to be dwindled, and increases wear extent, reduces the life-span; Weight person is burnt and is scrapped.In addition, along with the rising of temperature, the friction factor instability, under the constant situation of pressure, the moment of torsion of clutch transmits becomes with temperature, thereby causes job insecurity.
Summary of the invention
The objective of the invention is:
The electro-hydraulic comprehensive-control type clutch of a kind of long service life, pollution-free, working stability is provided.
Technological scheme of the present invention is:
Housing respectively with ring gear, gear, stop valve Spielpassung, ring gear and meshed transmission gear, at the housing internal fixation block teeth in January are arranged, be provided with oil pocket in month block teeth, be provided with stop valve between oil pocket, make and form high pressure oil alveolus A and low pressure oil alveolus B outside moon block teeth two ends respectively, stop valve is hinged by lever, pivot pin and the electromagnet that is fixed in the housing.
The invention has the beneficial effects as follows:
1) product performance are reliable, the life-span is long, cost is low;
Because what driving and driven parts adopted is meshed transmission gear, no slide relative, thereby can not resemble and wear problem is arranged the friction clutcch; In addition, transmitting medium is again hydraulic oil, can play lubrication, so product performance are reliable, the life-span is long, relative cost is low.
2) noise is little, impact is little, part life is long
Because what transmit the medium employing is hydraulic oil, and hydraulic oil under high pressure is resiliency compressible, thereby can be absorbed in vibration and impact that clutch produces in conjunction with the back suddenly, makes noise little.Simultaneously, the reduction of vibration, impulsive load also makes power train component load reduce, and improves the life-span of component.
3) pollution-free
Hydraulic oil is to be enclosed in clutch the inside, can not leak, thereby the protection environment, pollution-free.
4) installation manufacturing processing is simple, owing to adopted electromagnet, can simplify the structure of clutch, hydraulic part quantity, the minimizing assembling procedure that the minimizing requirement on machining accuracy is high, reduces product cost greatly, is easy to produce in batches.
When 5) the present invention not only can be applied to the vehicle of manual shift control, and can be applied to easily on the vehicle with automatic gear shifting system.

Embodiment
Working principle:
So-called electro-hydraulic comprehensive-control type clutch: be exactly utilize with engine crankshaft link together rotation ring gear be meshed formation pair of engaged gears pump with gear that is connected of gearbox.Month block teeth in crescent gear pump, have been added, to form the oil duct of a connection gear pump high and low pressure oil pocket, control opening and disconnecting of the hydraulic circuit that produces by gear pump with electric, relatively rotating of the gear of controlling ring gear and being meshed with it realized the transmission of power and a kind of clutch of interruption.
Working procedure:
By the switching of electromagnet 10, control the upper-lower position of stop valve 6, in order to the switching in loop between the control high low pressure oil pocket, the separation that promptly realizes clutch with combine.The switching origin clutch pedal control of power supply.
When gearshift needed cut-off clutch, driver's let slip the clutch made electromagnet 10 energisings.The electromagnetic force that electromagnet 10 produces, overcoming return spring 7 active forces pulling stop valve 6 by lever 12 effects moves down, open the loop between the high and low pressure oil pocket, oil pressure is identical in the high and low pressure oil pocket district, make between ring gear 3 (connecting) and the gear 5 (connecting) to relatively rotate, thereby realize clutch separation with the gearbox input shaft with engine crankshaft.
After the driver finishes gearshift, release the clutch pedal, electromagnet 10 outages, stop valve 6 pushes back stop valve 6 by return spring 7 active forces, block the loop between the high and low pressure oil pocket, oil pressure difference in the high and low pressure oil pocket district makes not have between ring gear 3 (connecting with engine crankshaft) and the gear 5 (connecting with the gearbox input shaft) to relatively rotate, thereby realizes the clutch combination.
