Embodiment
This controlled start and stop flexible gearing is made up of hydraulic speed-regulating gear unit 1, working oil flow is adjustable oil-way system 2, parallel-axes gears gear unit 3, planetary gear transmission unit 4, brake module 5, lubrication oil circulation cooling oil path system 6.Described hydraulic speed-regulating gear unit 1 is made up of input shaft 7, initiatively impeller 8, shell 9 and driven impeller 10, and initiatively impeller 8, shell 9 and driven impeller 10 form active chamber.Parallel-axes gears gear unit 3 is made up of 15 and sun gear 16 driven shaft 11, reduction gear.Planetary gear transmission unit 4 is made up of planet wheel 17 and output shaft 18.Brake module 5 is made up of spragging gear 12, brake axle 13 and brake disc 14.Hydraulic speed-regulating gear unit 1 is connected by driven shaft 11 with parallel-axes gears gear unit 3, and parallel-axes gears gear unit 3 connects planetary gear transmission unit 4 by sun gear 16, and is engaged with the spragging gear 12 of brake module 5 15 by reduction gear.Working oil flow is adjustable, and oil-way system 2 is connected (see accompanying drawing 1 ~ 2) with hydraulic speed-regulating gear unit 1, parallel-axes gears gear unit 3, planetary gear transmission unit 4 and brake module 5 by oil circuit with lubrication oil circulation cooling oil path system 6.
The know-why of these controlled start and stop flexible gearing start and stop is as follows:
1, this controlled start and stop flexible gearing is by controlling the active chamber liquid filled ratio q=0% of hydraulic speed-regulating gear unit 1, motor is in working machine and is separated operating mode, and startup that motor is non-loaded also reaches rated speed rapidly, completes the No Load Start of motor;
2, the liquid filled ratio of active chamber is increased gradually by the adjustable oil-way system 2 of working oil flow, the output revolutions of controlled start and stop flexible gearing is directly proportional to active chamber liquid filled ratio, as active chamber liquid filled ratio q=100%, working machine reaches rated revolution, machine smooth starting process of finishing the work;
3, reduce the liquid filled ratio of active chamber gradually, the mechanical energy making motor pass to working machine reduces gradually, the reduction progressively of working machine revolution, as active chamber liquid filled ratio q=0%, motor and working machine depart from, and working machine, by inertial rotation, now coordinates brake module 5 that working machine can be made steadily to stop;
4, at working machine initial start stage (now working machine is static), controlled start and stop flexible gearing output torque is directly proportional to active chamber liquid filled ratio, increase the liquid filled ratio of active chamber gradually simultaneously, the output torque of controlled start and stop flexible gearing is also increased to the peak torque close to motor gradually, therefore the peak torque deactivation load of motor can be utilized, this peak torque is greater than the starting with full load moment of working machine, can starting with full load working machine.
This controlled start and stop flexible gearing is the highly integrated transmission device of hydraudynamic drive and gear transmission, specific works process is: the power transmitting medium of hydraudynamic drive is fluid, fluid is sucked from fuel tank 19 by the adjustable oil feed pump 20 of flow, send into the active chamber be made up of active impeller 8, shell 9 and driven impeller 10, in active chamber, the active impeller be connected with motor or internal combustion engine output shaft 8 pairs of fluid do work, after fluid obtains kinetic energy and potential energy, high-speed punching is to driven impeller 10, and driven impeller 10 absorbs the kinetic energy of fluid and potential energy and is converted into mechanical energy and exports.Driven impeller 10, the initiatively ability of impeller 8 transferring power and the proportional relation of liquid filled ratio of active chamber, the liquid filled ratio of change active chamber just under the constant operating mode of active impeller 8 rotating speed, can change output torque and the output speed of driven impeller 10.Driven impeller 10 with by driven shaft 11, reduction gear to 15, sun gear 16, planet wheel 17, output shaft 18 the parallel-axes gears gear unit 3, the planetary gear transmission unit 4 that form be connected, mechanical energy is through efficiently conversion and the transmission of parallel-axes gears gear unit 3, planetary gear transmission unit 4, finally export by output shaft 18 rotating speed and moment that match with working machine characteristic, thus complete the flexibility transmission of power.Fluid flows back to fuel tank 19 along the drain tap of the outer rim of shell 9 afterwards.
The brake module 5 of this controlled start and stop flexible gearing is made up of spragging gear 12, brake axle 13, brake disc 14, when damped condition, brake disc 14 obtains an external positive pressure, produce a braking moment, to pass to by driven shaft 11, reduction gear 15 by spragging gear 12, sun gear 16, planet wheel 17, parallel-axes gears gear unit 3 that output shaft 18 forms, planetary gear transmission unit 4 gear drive, can reach anti-reverse to working machine emergency braking, the object of sliding prevention vehicle.
The above is the embodiment of this invention, above-mentioned illustrating is not construed as limiting flesh and blood of the present invention, person of an ordinary skill in the technical field can make an amendment above-mentioned embodiment or be out of shape after having read this specification, and does not deviate from the spirit and scope of the invention.
