Preferably, friction disk 30, the gap that is provided with between 32 are about 1mm, and in the known wet clutch of existing technology, this gap is about 1/10 millimeter.
According to the preferred implementation shown in Fig. 1; Transmitting set 10 also comprises torque-converters 36; Said torque-converters 36 flexibly is connected to the jack shaft 24 that hydraulic pressure is controlled coupling mechanism 22 in the ingress; And be connected to gearbox 38 in the outlet port, and this gearbox 38 links to each other with the hydrostatic unit 40 that turns to, so that can give (conf é rer) each output shaft 14a, the 14b of transmitting set 10 from the output shaft 25 of torque-converters 36 with different actuating speeds.
Similar with the multi-disc type wet clutch 22 that is equipped with oil circulating pump 26, torque-converters 36, gearbox 38 with hydrostatic turn to unit 40 preferred each all link to each other with oil hydraulic pump 44,46,48.The function of these oil hydraulic pumps 26,44,46,48 is to guarantee that the needed oil from main oil reservoir 20 circulates in each parts of transmitting set 10; Particularly so that can effectively cool off, said each parts are multi-disc type wet clutch 22, torque-converters 36, gearbox 38 and the hydrostatic unit 40 that turns to.
Notably; Transmitting set 10 comprises can select starting mechanism 50 and from main hydropress group 52; The said hydraulic pressure of selecting starting mechanism 50 to be used for reducing to make oil in the outlet port of multi-disc type wet clutch 22 circuit pumps 26, and saidly comprise oil conservator 54 (see figure 2)s and be used for the heating machanism 56 that heat packs is contained in the oil of oil conservator 54 from main hydropress group 52.This can control hydraulic pressure from main hydropress group 52 and control coupling mechanism 22, and particularly hydraulic actuator 28, is used to make transmission shaft 12 to separate with input shaft 24.
According in the preferred implementation of the present invention shown in Fig. 1; Transmitting set 10 also comprises can select starting mechanism 58,60,62; They respectively with pump 44,46 with 48 each link to each other, be used for being reduced to respectively the hydraulic pressure in outlet port that torque-converters 36, gearbox 38 and hydrostatic turns to these oil hydraulic pumps of unit 40.
According to preferred implementation of the present invention, these step-down mechanisms 50,58,60,62 comprise that at least one can be selectively with the valve of oil from each pump guiding main oil reservoir 20.
Be used for heat packs and be contained in heating equipment, can comprise the resistor that is immersed in the oil conservator 54 of main hydropress group 52, perhaps preferably, comprise the induction type heating machanism from the oil of the oil conservator 54 of main hydropress group 52.The induction type heating machanism can also conserve energy, because it has reduced the energy loss that the wall owing to heating oil conservator 54 produces.According to another modification, be used for heat packs and be contained in the exchanger on the preheating circuit that heating machanism from the oil of the oil conservator 54 of main hydropress group 52 comprises the motor 13 that places track-laying vehicle 11.
Also comprise oil hydraulic pump 55 from main hydropress group 52, this oil hydraulic pump can activate through motor.This moment, the motor (not shown) can be a motor, in the case, was advantageously supplied power to it by the battery of motor-driven track-laying vehicle 11.But because severe cold, battery can not be configured for to the stable energy from the actuating engine power supply of the pump of main hydropress group.Therefore; According to preferred implementation of the present invention; Comprise the oil hydraulic pump that activates by air motor from main hydropress group 52; Said air motor can perhaps be supplied with pressurized air by the external compressed air storage of steel cylinder class to air motor by the pressurized air storage that exists in the motor-driven track-laying vehicle 11.In fact, pressurized air is formed in the stable energy under the low temperature very.
As it be shown in fig. 2, hydraulic pressure is controlled coupling mechanism 22 and is preferably included the actuator that is made up of dual-effect hydraulic ram 28, and each in two hydraulic chambers 64,66 of main hydropress group 52 and ram 28 fluid independently is communicated with.So; This can control the direction translation of friction disk 32 along friction disk 30 from main hydropress group 52; So that will transmit to the jack shaft 24 of transmitting set 10 from the driving power of input shaft 12; Perhaps opposite, these friction disks 30,32 are separated from each other, so that no longer the driving power of input shaft 12 is passed to the jack shaft 24 of transmitting set 10.
Preferably; As it be shown in fig. 2; Transmitting set 10 of the present invention also comprises by the 68a of mechanism, 68b, 68c and 68d from main hydropress group 52 fuel feeding, is used for friction disk 30,32, torque-converters 36, gearbox 38 and the hydrostatic unit 40 that turns to of lubricated wet clutch 22 respectively.
Again preferably, be communicated with being used to make the hydrostatic mechanism's fluid that turns to unit 40 to throw off from main hydropress group 52 from transmitting set 10.
Preferably, also be communicated with from main hydropress group 52, thereby can selectively make stopping brake mechanism 15 stop start with the hydraulic pressure operating-controlling mechanism fluid of the stop device 15 that is used to control track-laying vehicle 11.Usually, stopping brake mechanism 15 comprises two pawls, and in the rest position of stopping brake mechanism, said pawl vises the brake disc that is fixedly connected with one of output shaft under the effect of spring.Under the effect of known hydraulic pressure operating-controlling mechanism, said pawl can be separated from each other, and same output shaft is rotated freely.
At last, preferably, be communicated with the hydraulic pressure operating-controlling mechanism fluid of servo brake device 16 from main hydropress group 52, so that can selectively start servo brake device 16.Usually, servo brake device 16 comprises two pawls, and in the rest position of servo brake device 16, said pawl separates with the brake disc that one of output shaft rotational fixation is connected, so that make relevant output shaft to rotate.Under the effect of hydraulic pressure operating-controlling mechanism, said two pawls will vise the brake disc that is connected with the output shaft rotational fixation, so that prevent the output shaft rotation.
The operation of transmitting set 10 of the present invention is directly from the description that has just provided.
Owing to open the valve 50,58,60,62 that links to each other with each parts of transmitting set 10; Oil pressure in the outlet port of pump 26,44,46,48 possibly descend, and the influence that causes is more insensitive---to hinder any motion of the parts of transmitting set usually---by cold and oil that condense.
In addition; Its suitable oil conservator 54 is housed can the controlling input shaft 12 from main hydropress group 52 and separate of---this oil conservator can be heated by means of heating machanism 56---with jack shaft 24, thus input shaft 12 no longer stands the resistance torque that produced with the jack shaft 24 of the output shaft 14a of transmitting set, transmitting set 10 that 14b flexibly is fixedly connected.
Since lubricating structure 68a, 68b, 68c, 68d between the starting period of low temperature very by from main hydropress group 52 fuel feeding; Friction disk 30,32 is lubricated; Torque-converters 36, hydrostatic turn to unit 40 and gearbox 38 between the starting period of low temperature by fuel feeding, thereby transmitting set 10 can move between this starting period.Come from hot lubrication oil circulation from main hydropress group 52 up to main oil reservoir 20.So; Auxiliary oil conservator 54 from main hydropress group 52; When the oil that when beginning, in whole device 10, condenses becomes liquid again under the effect of the heating of transmitting set 10; Particularly because the operation of motor and because the rotation of speed change parts when being heated, can make transmitting set 10 start with the deep fat of very small amount.
In addition, because friction disk 30, bigger relative gap between 32, the oil phase that condenses applies the moment that reduces for the transmitting set of existing technology between friction disk 30 and 32.
In fact, in the transmitting set of existing technology, the relative gap between the friction disk reduces, and this makes and can obtain the short relatively response time at normal run duration.Correspondingly, owing under the situation of very low temperature starting, in the internal friction disc space, exist the oil that condenses, this less clearance can cause and make wet clutch inaccessible.
In addition, in the transmitting set of existing technology, the input shaft of transmitting set is because the oil that condenses that low temperature caused and fixed very, makes input shaft rotate necessary moment and reaches near the given maximum moment of motor when the operation.The electric starter of motor can not send so big moment, in addition the extraneous auxiliary device of preheating oil and boiler engine type or in the firing chamber injecting compressed air unit that is connected with the input shaft rotational fixation is rotated.
With respect to the transmitting set of existing technology, though another advantage of transmitting set of the present invention be under very low ambient temperature, also can make its starting through drawing motor-driven track-laying vehicle.
In fact, use the transmitting set of existing technology can not carry out this type of starting, because the transmitting set of existing technology needs:
1. releasing stopping brake, for security reasons, this type of braking is inaccessible under the situation that lacks energy resource supply;
2. locking and stop using the hydrostatic unit that turns to, thus trailed vehicle can along the track of forcing by tractor with can not be to be that the ground of strict straight line, the configuration of track are advanced;
3. reduce by the oil that condenses and be applied to the braking moment on the parts of transmitting set;
4. fixed connection power transmission chain, thus the rotation of crawler belt impels the live axle rotation;
5. create the hydraulic pressure that is used to activate clutch, thereby the dynamofluidal not at the same level of power transmission is fixedly connected with.
So, use the transmitting set of existing technology, these step neither ones can be implemented.
In transmitting set illustrated in figures 1 and 2, selectively with the lower component fluid be communicated with from main hydropress group 52:
-be communicated with the operating-controlling mechanism of stop device 15, so that can make stop device 15 stop start,
-be communicated with the operating-controlling mechanism of servo brake device 16, if so that trailed track-laying vehicle driver needs, servo brake device 16 is started;
-connection is used for the hydrostatic unit 40 that turns to from the mechanism that transmitting set 10 is thrown off, so that motor-driven track-laying vehicle can be advanced along the shape on track of being forced by tractor and ground.
Can reduce the braking moment that the oil that condenses applies each parts of transmitting set from main hydropress group 52; Particularly when separating; In the very first time; The jack shaft 24 of transmitting set is separated, then along with particularly oily temperature rise makes jack shaft 24 connect gradually again with input shaft 12 because motor operation and/or friction disk 30,32 rub each other with input shaft 12.
When ambient temperature is low excessively, cause in the time of can not being used the transmitting set of existing technology because its crawler belt checks, transmitting set 10 can also draw the motor-driven track-laying vehicle that this transmitting set is housed in a similar fashion.
Certainly, the present invention only is limited to above-mentioned mode of execution, and only otherwise exceed scope of the present invention, many modification all are possible.
