Detailed description of the invention
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Car hosit in motion, starts frequently and stops, and can expend comparatively macro-energy.When hoisting crane brakes, lock torque is comparatively large, finally dissipates with the form of friction heat, causes the waste of energy.In order to improve the energy utilization efficiency of hoisting crane, have employed oil-liquid hybrid electric technology in the hoisting crane at place of the present invention, during vehicle start, access drives vehicle, after normal traveling, throw off hybrid power system, this just needs a kind of coupling device with clutch function to realize this function.Oil-liquid hybrid electric refers to that energy source has the chemical power of hydraulic energy and diesel oil, and through power coupling, forming combination drive power, is a kind of energy saving technology.Power coupling is at hybrid power system operationally, gets involved and drives vehicle, needs to work together with driving engine, completes the fusion of power, be delivered to power element by an output shaft after two power transmission chain superpositions.
The schematic diagram of hoisting crane hybrid power transmission chain as shown in Figure 1, mainly comprise: driving engine 31, change speed gear box 34, power takeoff 33, engine clucht 32 (can according to circumstances select dry type or liquid clutch), pump/motor 36, energy storage 35 etc., power takeoff 33 are provided with and can realize connecting and the power-transfer clutch 37 disconnecting hybrid power system messenger chain.When car brakeing, drive pump/motor 36 braking force to be converted into hydraulic energy and be stored in energy storage 35, thus braking energy during reclaiming crane brake; When vehicle start, energy storage 35 discharges hydraulic energy and is converted to the mechanical energy driving vehicle to advance, and drives pump/motor 36, produces drive torque, drives vehicle to advance; During normal traveling, cut off hybrid power system, a dependence driving engine 31 provides power.Pump/motor 36 is a kind of secondary components, can use as pump, again can as motor operations.When recuperated energy, under being operated in pump state; When releasing energy, with motor condition work.
And the power takeoff of prior art can not meet the power coupling demand of hoisting crane hybrid power system, thus the invention provides a kind of power takeoff with clutch function, for transmitting or disconnecting moment, will be described in detail below.
A kind of power takeoff with clutch function provided by the invention, as shown in Figure 2, comprise: input shaft 12, speed reduction gearing and power-transfer clutch 37, the input end of power-transfer clutch 37 is connected with the mouth of speed reduction gearing, mouth is connected with pump/motor 36, the input end of speed reduction gearing is connected with input shaft 12, and power-transfer clutch 37 can connect or disconnect the transmission of power between input shaft 12 and pump/motor 36.
The present invention can be used in hoisting crane with the power takeoff of clutch function or performs the vehicle of other task, for its work in hybrid power system as shown in Figure 1, when car brakeing, power-transfer clutch 37 adhesive, lock torque is passed to pump/motor 36 by power takeoff 33, now pump/motor 36 uses as pump, and is stored in by hydraulic energy in energy storage 35; When vehicle launch, energy storage 35 discharges hydraulic energy and is converted to the mechanical energy driving vehicle to advance, and now drives pump/motor 36 to be used as motor, produces drive torque, carry out the advance of couple drive vehicle with the drive torque of driving engine 31; When after normal vehicle operation, power-transfer clutch 37 disconnects, and a dependence driving engine 31 provides power driven vehicle to advance.As can be seen here, this kind can make hoisting crane or other vehicle in motion with the power takeoff of clutch function, by clutch smooth and steady realize disconnect or in conjunction with power chain, very large impulsive force can not be produced, reduce the adverse effect to driving system function and life-span, thus can get involved at any time and depart from hybrid power system.
In one embodiment of the invention, power-transfer clutch 37 is one-piece construction, is connected removably with the mouth of speed reduction gearing.This connection structure is comparatively simple, highly versatile, and produces fault once power-transfer clutch, and it is very convenient to change.
When adopting the power-transfer clutch of above-mentioned absolute construction, power-transfer clutch 37 comprises: be arranged on the clutch-bell cover 4 on speed reduction gearing, be arranged on clutch end cover 6 on clutch-bell cover 4 and engaging and disengaging gear.According to the implementation of engaging and disengaging gear, fluid pressure type or electromagnetic clutch can be selected, but be not limited thereto.
Hydraulic clutch is adopted in a specific embodiment, engaging and disengaging gear comprises: external friction dish 5, internal friction disc 10, the Bringing-back mechanism being arranged on internal friction disc 10 side, the piston 9 being arranged on internal friction disc 10 opposite side and control port 19, when control port 19 obtains control fluid, piston 9, under the promotion controlling fluid, makes the end contact transferring power of internal friction disc 10 and external friction dish 5; When control port 19 get out of hand fluid, internal friction disc 10 is thrown off with external friction dish 5 under the effect of Bringing-back mechanism, disconnects transmission of power.Wherein, Bringing-back mechanism can be made up of platen 21 and wavy spring 20, and wavy spring 20 acts on internal friction disc 10 by platen 21.Internal friction disc 10 in power-transfer clutch 37 and adopt wavy spring 20 to separate between external friction dish 5, ensure that and can effectively be separated between friction face, simplify the structure, and reduces processing and manufacturing difficulty.
Preferably, be the mode of multi-disc contact between external friction dish 5 and internal friction disc 10, when power-transfer clutch 37 adhesive, multiple friction face contacts common transferring power simultaneously, can reach larger carry-over moment, ensures that power takeoff 33 carries enough large moment of torsion.Adopt this engaging and disengaging gear that power-transfer clutch bearing torque can be made large, compact conformation, thus operationally rotor inertia is little to make it, is conducive to the quick response of device, is active in one's movements.
Further, power-transfer clutch 37 can also comprise surface bearing 18, and piston 9 makes internal friction disc 10 contact transferring power with external friction dish 5 by surface bearing 18.Piston 9 in power-transfer clutch 37 compresses internal friction disc 10 by surface bearing 18, in conjunction with more steady.
