Concrete, when the present invention manufactures assembling and uses, as described below.
As illustrated in fig. 1 and 2, the invention discloses a kind of power take-off 10, comprise housing 11, input gear 12, output shaft assembly 14 and oil supply system, also comprise the bearing cap 15 and the valve seat 16 that are connected with housing 11 two ends.Oil pump 20 in oil supply system provides hydraulic oil source, and the high pressure oil producing, for lubrication power take-off 10, is power take-off 10 combinations and the separated pilot pressure that provides simultaneously.Oil pump 20 can be arranged on speed changer, by power sources such as motors, is driven.
On power take-off 10 is applied in by engine-driven highway truck, as a dismountable fixture, use, by bolt, be installed on the speed changer being connected with motor, oil supply system can adopt the hydraulic oil source on speed changer.Power take-off 10 is equally applicable to be installed in motor, motor, truck transmission, tractor, engineering vehicle, sea-freight instrument or other rotating power source.
As shown in Figure 1, housing 11 comprises inner chamber 19, opening 21 and bolt through-hole 22, if certain road vehicle will be used power take-off 10, available bolt, by bolt through-hole 22, is installed to power take-off 10 on the speed changer on road vehicle.Output shaft assembly 14 is installed in the inner chamber 19 of housing 11 completely.Input gear 12, by bearing pin 13, left support bearing 23 and right support bearing 24, is installed in the opening 21 of housing 11.
Output shaft assembly 14 comprises output shaft 25, output gear 26, clutch 27.Output shaft assembly 14 outlet sides are installed to by output terminal bearing 28 in the bearing hole of bearing cap 15, and input side is installed in the bearing hole of housing 11 by input end bearing 29.Output shaft 25 output terminals directly or indirectly connect fixture, such as oil pump, oil hydraulic motor etc.Output gear 26 comprises gear and splined hub, by bearings, is arranged on output shaft 25, and when clutch 27 is separated, output gear 26 dallies on output shaft 25, the gear on it and 18 engagements of transmission gear.
As shown in Figure 1, bearing cap 15 is connected with housing 11 left side junction planes by bolt, comprises output terminal bearing 28 and output terminal oil sealing 30.Valve seat 16 is connected with housing 11 right side junction planes by bolt, and there is blind hole inside, and input end oil sealing 31 is installed.At valve seat 16 outer surfaces, there is tapped hole for erection joint 41.Valve body openings 32 on valve seat 16 is for installing solenoid valve 42.Solenoid valve comprises electromagnetic coil, can control its switch by single electrical signal, thereby controls the break-make of high pressure oil from oil pipe 40 to oil duct 39.
Clutch 27 comprises 33, one groups of antithesis sheets 34 of friction plate of one group of wet type, tooth hub 35, and clutch piston 36, clutch piston seat 37 and Returnning spring 38, be arranged on output shaft 25.During assembling, every a slice friction plate 33, place a slice antithesis sheet 34, friction plate 33 is arranged on tooth hub 35 by spline, and antithesis sheet 34 is installed in the splined hub of output gear 26 by spline.Tooth hub 35 and clutch piston seat 37 are fixed on output shaft 25.When clutch 27 is separated, friction plate 33 and antithesis sheet 34 freely rotate each other, now allow to relatively rotate between output gear 26 and tooth hub 35 and output shaft 25.When clutch 27 in conjunction with time, friction plate 33 and antithesis sheet 34 compress each other, now between output gear 26 and tooth hub 35 and output shaft 25, nothing relatively rotates, can moment of torsion and the power of power take-off 10 will be entered, by transmission gear 18, output gear 26, clutch 27, be delivered on output shaft 25, and drive the fixture being attached thereto to rotate.
The combination of clutch 27 is controlled by the pressure oil of the oil duct 39 by output shaft 25.Oil duct 39 communicates with the clutch cavity between clutch piston 36 and clutch piston seat 37.When the pressure oil that oil pump 20 produces is delivered to the cavity between clutch piston 36 and clutch piston seat 37 by oil pipe 40, joint 41, solenoid valve 42, oil duct 39, will promote clutch piston 36 moves right, compression reseting spring 38, thus make the complete combination of clutch 27.While there is no pressure oil or pressure oil lower than certain numerical value in oil duct 39, clutch 27 will be separated under the spring-force driven dual of Returnning spring 38.
As shown in Figure 3, the invention discloses a kind of further improved power take-off 10.The represented power take-off 10 of Fig. 3 is on the architecture basics of Fig. 1 and Fig. 2, to add the improvement of making after break 50.
When solenoid valve 42 power-off, power take-off 10 is not worked, and in oil duct 39 and prolongation oil duct 51, there is no pressure oil, thereby now clutch cavity does not all have pressure oil with braking cavity yet.This makes clutch 27 in separated state, does not have moment of torsion to be delivered on the fixture being connected with output shaft 25 by power take-off 10 with power.Meanwhile, brake spring 55, in releasing state, is pressed in brake disc 53 limit position of high order end.According to foregoing description, will make nothing between brake disc 53 and brake casing 52 relatively rotate, output shaft 25 is in complete lockup state.When solenoid valve 42 energising, the high pressure oil that oil pump 20 produces is by oil pipe 41, joint 42, enter into and extend oil duct 51, and now enter the high pressure oil of braking cavity between brake piston 54 and brake disc 53, by first promoting brake disc 53, move right, compression brake spring 55, brake disc 53 will disengage with brake casing 52, and brake disc 53 and output shaft 25 are removed lockup state.When enter the high pressure oil of clutch piston 36 and clutch piston seat 37 make clutch 27 completely in conjunction with time, power take-off 10 is just started working, can its moment of torsion and power will be entered, by transmission gear 18, output gear 26, clutch 27, be delivered on output shaft 25, and drive the fixture being attached thereto to rotate.
When design, analyze the elasticity coefficient of oil pressure active area and compression reseting spring 38 and the brake spring 55 of two cavitys, while guaranteeing to have high pressure oil in oil duct 39 and prolongation oil duct 51, brake disc 53 and output shaft 25 are first removed locking, then clutch 27 combination completely again, power take-off 10 ability transmitting torques and power are given the fixture being attached thereto.
From description above, when the road vehicle that power take-off 10 is installed is not when power take-off 10 is worked, i.e. solenoid valve 42 power-off, the fixture being connected with output shaft 25 rotates possibly at random, has potential safety hazard.And the road vehicle that the power take-off 10 that break 50 is set after improvement is installed is not when power take-off 10 is worked, be solenoid valve 42 power-off, the complete locking of fixture being connected with output shaft 25, only when solenoid valve 42 energising, output shaft 25 is just removed locking, and this is highly beneficial to safety in production operation.And when reality is used, because the fixture being connected with power take-off 10 is generally all with safety protection device, thereby the mentioned power take-off that is provided with break 50 10 of the present invention can be according to actual conditions by user's choice for use.
