Description
Technical field
The utility model relates to power take-off field, specifically, specially refers to a kind of Full-power takeoff that adopts two-stage speedup structure.
Background technique
Full-power takeoff general introduction is the power take-off that can obtain maximum engine torque, general power taking on gearbox one axle between clutch and gearbox.Being mainly used in cement pump truck, high-altitude fire fighting truck etc. needs on powerful special car.When Full-power takeoff uses, vehicle must stop, and this is different from the just power taking of can limit walking of non-Full-power takeoff.
Existing Full-power takeoff is due in structural design, have that bearing life is short, operating noise large, internal gear and bearing insufficient because lubricating, the problem such as operating temperature is higher.
Model utility content
The purpose of this utility model is to provide a kind of Full-power takeoff that adopts two-stage speedup structure, to address the above problem.
The technical problem that the utility model solves can realize by the following technical solutions:
Adopt a Full-power takeoff for two-stage speedup structure, comprise power take-off housing and the transmitting assemblies that is arranged at power take-off object inside; It is characterized in that: described transmitting assemblies comprises input unit, temporary location and output unit; Described input unit comprises input shaft, input gear, oilless bearing, declutch shift shaft and spline housing, and described temporary location comprises jack shaft and intermediate gear, and described output unit comprises output shaft and output gear; The end of described input shaft is provided with input gear and oilless bearing, and described spline tooth overlaps and output gear interlock, and one end of described declutch shift shaft and the interlock of spline tooth cover, for controlling the occlusal position of spline tooth cover and output gear; The two ends of intermediate gear respectively with input gear and output gear interlock.
Further, described input gear, intermediate gear and output gear are elongated gear.
Further, described jack shaft is provided with hydraulic-pressure pump, is used to transmitting assemblies to be lubricated.
Further, described power take-off housing is provided with water-cooling tube, and described water-cooling tube connects radiator, for reducing the gear oil temperature in power take-off housing.
Further, described power take-off housing is provided with radiating fin.
Compared with prior art, the beneficial effects of the utility model are as follows:
Adopt the mode of input shaft clutch, engaged power output with input gear by fork controls spline tooth cover.Rotary inertia is little, and structure maturation is reliable, processes easy.Between input gear and output shaft, utilize oilless bearing to substitute conventional needle bearing, effectively avoided causing not needle bearing along bad problem because this place is lubricated.
Brief description of the drawings
Fig. 1 is the structural representation of Full-power takeoff described in the utility model.
Fig. 2 is the drive system figure of Full-power takeoff described in the utility model.
Number in the figure explanation: input shaft 1, input gear 2, oilless bearing 3, output gear 4, declutch shift shaft 5, spline tooth cover 6, intermediate gear 7, hydraulic-pressure pump 8.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
Referring to Fig. 1 and Fig. 2, a kind of Full-power takeoff that adopts two-stage speedup structure described in the utility model, comprises power take-off housing and the transmitting assemblies that is arranged at power take-off object inside; Described transmitting assemblies comprises input unit, temporary location and output unit; Described input unit comprises input shaft 1, input gear 2, oilless bearing 3, declutch shift shaft 5 and spline tooth cover 6, and described temporary location comprises jack shaft and intermediate gear 7, and described output unit comprises output shaft and output gear 4; The end of described input shaft 1 is provided with input gear 2 and oilless bearing 3, described spline tooth cover 6 and output gear 4 interlocks, and one end of described declutch shift shaft 5 and 6 interlocks of spline tooth cover, for controlling the occlusal position of spline tooth cover 6 and output gear 4; The two ends of intermediate gear 7 respectively with input gear 2 and output gear 4 interlocks.
Described input gear 2, intermediate gear 7 and output gear 4 are elongated gear, have avoided producing axial force in work, have extended the working life of power take-off bearing.
Described jack shaft is provided with hydraulic-pressure pump 8, is used to transmitting assemblies to be lubricated.Thereby effectively solved because of output shaft cog and bearing because of lubricated insufficient, cause temperature rising, bearing damage, the phenomenon of gear breaking.
Described power take-off housing is provided with water-cooling tube; described water-cooling tube connects radiator, in the time that power take-off is worked, allows little water pump work simultaneously, passes through water-cooling tube; gear oil temperature in gearbox and power take-off is reduced, effectively protected Sealing, bearing to lose efficacy because of excess Temperature.On power take-off housing, be provided with radiating fin, increased heat diffusion area, also can play a role to the reduction of power take-off bulk temperature simultaneously.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
