Both at home and abroad in industry reserved vehicle of the same type, mostly adopt an auxiliary engine to provide power to apparatus for work, so, power arrangement space is increased; The car also having is all placed on all outputting powers in a transmission gearbox, and for avoiding transmission gearbox excessive and simple to operate, this transmission gearbox is conventionally without the engine installation that cuts off operation, and while causing engine operation, pump must be worked, and affects the life-span of operation pump.
Can overcome above defect from the transmission gearbox of engine free end power taking, in the situation that meeting general layout requirement, service condition is good.On recovery tractor or on special-use vehicle of the same type, arrange that such pump drive case is necessary.Can be applicable to again civilian goods market-for example the can be applicable to propulsion box of various special-use vehicle apparatus for work.
Summary of the invention
Technical problem to be solved in the utility model is: this device is in when assembling, realizes easily connecting of engine power and main pump; This device meets in the time that piggyback pod hangs out, and is conveniently connected/frees with engine power; This device reduces engine free end torsional oscillation well. can eliminate the amplitude of certain limit; In the time of Vehicle Driving Cycle, (while not using apparatus for work) can cut off the power of driving pump.
The utility model is realized by following technical scheme:
A kind of pump drive case apparatus from the power taking of engine free end, comprise pump drive case and ball cage universal coupling, described pump drive case comprises casing, gearshift, input shaft, input gear, output gear and output shaft, input shaft is connected with engine free end by ball cage universal coupling, output gear be arranged on output shaft and and input gear engage, described gearshift comprises gearshift tooth cover, shift fork, power shift gear and driving gear, shift fork is contained in gearshift tooth cover, power shift gear coordinates with gearshift tooth cover, driving gear can engage with power shift gear or free, driving gear and input gear composition dual gear, driving gear and power shift gear are all contained on input shaft, input shaft directly drives power shift gear rotation, but directly do not drive driving gear rotation.
Ball cage universal joint shaft by its upper with tooth cover with on engine free end with output gear overlap and be connected.
Between the tooth cover of engine free end output gear cover and ball cage universal joint shaft, cushion blocking is installed.
Major part pump drive case of the present utility model, the tooth cover that design motivation switches thereon, be used for conveniently realizing combination and the disconnection of main pump power. while making Vehicle Driving Cycle (while not using apparatus for work), can cut off the power of driving pump, utilize the main pump life-span.

Fig. 3 is pump drive case gearshift schematic diagram.
Detailed description of the invention
As Figure 1-3, the utility model is a kind of pump drive case apparatus from the power taking of engine free end, comprise pump drive case and ball cage universal coupling 3, described pump drive case comprises casing 4, gearshift 5, input shaft 6, input gear 7, output gear 8 and output shaft 9, input shaft 6 is connected with engine free end by ball cage universal coupling 3, output gear 8 be arranged on output shaft 9 and and input gear 7 engage, described gearshift 5 comprises gearshift tooth cover 10, shift fork 11, power shift gear 12 and driving gear 13, shift fork 11 is contained in gearshift tooth cover 10, power shift gear 12 coordinates with gearshift tooth cover 10, driving gear 13 can engage or free with power shift gear 12, driving gear 13 forms dual gear with input gear 7, driving gear 13 is all contained on input shaft 6 with power shift gear 12, input shaft 6 directly drives power shift gear 12 to rotate, but directly do not drive driving gear 13 to rotate.
Ball cage universal joint shaft by its upper with tooth cover with on engine free end with output gear overlap 1 and be connected.
Between the tooth cover of engine free end output gear cover 1 and ball cage universal joint shaft, cushion blocking 2 is installed.
Shift fork 11 is at initial condition, and pump drive case is in neutral position state; The power of driving engine is cut off; Shift fork 11 moves, gearshift tooth cover 10 and driving gear 13 combinations, and the transmission of power of engine free end, drives main pump work.
In the utility model, can realize easily connecting of engine power and main pump for solving in when assembling, in the time hanging out, can facilitate and problem that engine power is freed, between engine free end and pump drive case, adopt ball cage universal coupling to be connected 3; For reducing engine free end torsional oscillation, between the tooth cover of engine free end output gear cover and ball cage universal joint shaft, increase cushion blocking 2, shock pad 2 thickness are divided into three groups, when assembling, choose as required, make effectiveness in vibration suppression reach best; At the inner gearshift tooth cover 10 that increases a powershift of pump drive case, can conveniently realize combination and the disconnection of main pump power by operating lever operation. while making Vehicle Driving Cycle (while not using apparatus for work), can cut off the power of driving pump, utilize the main pump life-span.
