Wet clutch
Technical field
The present invention relates to a kind of clutch, and in particular to a kind of wet clutch for heavy-duty car.
Background technology
Clutch is the part being directly associated with electromotor in car transmissions, and it is responsible for cut-out and the combination of power and drive system, it can be ensured that gentle start during vehicle starting, also can guarantee that smooth-going during gearshift, also prevent drive system overload.At present; the clutch used on heavy vehicle is mostly mechanical mechanism; complex structure, service life are short, as the reaction of its occlusion is very fast and gmatjpdumamicss are big; friction plate can produce high temperature; clutch is often caused to break down, once breaking down, flywheel, platen, clutch disc are required for changing; heavy vehicle average half a year is accomplished by changing once, and replacement cost is higher.
The content of the invention
The technical problem to be solved is to overcome above-mentioned deficiency, there is provided a kind of wet clutch, and the clutch is lowered the temperature to friction plate using cooling oil, effectively increases the service life of clutch, and pressure distribution is uniform, and transmitting torque is big.
Technical scheme:A kind of wet clutch,It includes an axle 1,One axle bearing 2,Protecgulum 3,Fore shell 4,Connection gear 5,Driven friction disk 6,Active friction plate 7,Active gear ring 8,Return spring 9,Piston 10,Engagement cylinder 11,Back cover 12,Bearing 13,Oil return opening 14,Engagement hydraulic fluid port 15,Cooling hydraulic fluid port 16,One shaft-cup 17,One axle 1 is arranged on change speed gear box by an axle bearing 2,One shaft-cup 17 is located on an axle 1,Engagement cylinder 11、Back cover 12 is located on a shaft-cup 17,Bearing 13 is provided between back cover 12 and a shaft-cup 17,Piston 10 is provided with engagement cylinder 11,Piston 10 is provided with return spring 9 with engaging between cylinder 11,Oil return opening 14 is additionally provided with one shaft-cup 17、Engagement hydraulic fluid port 15、Cooling hydraulic fluid port 16,Engagement hydraulic fluid port 15 is connected with engagement cylinder 11,Active friction plate 7 is located at the front portion of engagement cylinder 11,Driven friction disk 6 is located on the spline of an axle 1,Fore shell 4 is located on engagement cylinder 11,Active gear ring 8 is located at fore shell 4 and engages cylinder between 11,Protecgulum 3、Connection gear 5 is located on fore shell 4.
The present invention is had the advantages that compared with prior art:Clutch disc of the present invention is soaked in oil; cooling oil shields to friction plate; make power transmission smooth gentle, fault rate is relatively low, high temperature resistant; effectively increase the service life of clutch; replacement cost is reduced, and without the special gap for adjusting friction plate, pressure is announced uniform; power transmission smooth-going, and transmitting torque is big.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure:Mono- axles of 1-, mono- axle bearings of 2-, 3- protecgulums, 4- fore shells, 5- connection gears, 6- driven friction disks, 7- active friction plates, 8- active gear rings, 9- return springs, 10- pistons, 11- engagement cylinders, Sales after 12-, 13- bearings, 14- oil return openings, 15- engagement hydraulic fluid ports, 16- cooling hydraulic fluid ports, mono- shaft-cups of 17-.
