Agricultural visual barrels with differential, switchable Planetary gears and spur gears.

Differential axle drives are known with eineat two-speed Planetary gears and a pair of drive bevel gears, which is mainly driven by a © ® Sohalt gear arranged in the longitudinal direction of the vehicle, are known to be long and are not very suitable for equipment carriers, for example «,

ryjTg is that dajj is differential through the hollowed output shaft one parallel to the drive axis lying gearbox is driven, and that one on the hollow drive shaft rotatably and longitudinally displaceably mounted Sohaltmuffe is available, welehe optionally with the sun gear of the planetary gear transmission or with the differential housing can be coupled.

An engine with the characteristics of the SKOSKsälg is through short and compact design excellent »The hollow shaft enables a space-saving attachment of a power take-off drive < >

Heue— The drawing represents two embodiments of the Sf

it is

lig. 1 an engine with a bevel gear differential in longitudinal section in a schematic representation?

Mg »2 another embodiment with buckets of spur gear differences» rentialo

Dig- 1 represents an engine for an equipment carrier " A motor shaft 1 arranged in the longitudinal direction of the vehicle drives a clutch housing, in which optionally the clutch disc 2 or 3 can be switched on »The clutch disc

Einbe 2 drives the gear pinion of a bevel gear reversing gear 4 and the clutch disc 3 drives a pair of spur gears 5. This drives a PTO shaft 6 depending on the engine. Between the shift gear change gear 7 located transversely to the direction of travel and a spur gear ^{differential 17 is a planetary gear reduction 16, 18, the input shaft 7 a of} the gear change gear 7 is optionally driven in both directions of rotation by the esgel gear reversing gear 4,

The hollow output shaft 14 of the gearbox 7 forms at the same time the input shaft of the planetary gear reduction or the spur gear differential 17 »one on the hollow shaft 14 in a rotationally fixed manner and longitudinally displaceably mounted sliding sleeve 15 can either be connected to the sun gear 16 or to the housing 17 of the differential be coupled. Accordingly, the rotation of the hollow shaft 14 is reduced by the planetary gears 18, or directly on the Transfer differential housing 17 "

The fixed pivot pin 11 in the housing 17 are used both for Storage of the planetary gears 18 as well as the differential spur gears 22 and 23 respectively. Two spur gears 22 and 23 are known in FIG

Way in engagement with one another and mounted on two different journals 11, of which only the one on which a planetary gear 18 is mounted is shown. »Another journal, not shown, on which the spur gear 23 is rotatably mounted _? can be shorter than the illustrated pin 11 = the spur gear 20 is connected to the drive half-axis 12 and the spur gear 21 is connected to the drive half-axis 15. The two half-axes act on reduction gears 24, 25? which drive the wheels 26.

A spur gear 8 is rotatably mounted on the hollow shaft 14, which is in engagement with a further spur gear 8a «The spur gear 8a drives a bevel gear 9» which drives the PTO shaft 6 depending on the path »

The bearing of the planetary gears 18 and the spur gears 22 of the differential on the same journal 11 enables one compact design of an axle differential with an adjacent one Switchable planetary gear reduction “The hollow drive shaft 14 of the axle differential also allows a cheap Accommodation of a path-dependent PTO drive in a free space between the gearbox 7, the bevel gear reversing gear 4 and the planetary gear reduction 16, 18, 19

Pig. 2 shows another embodiment of an axle differential, in which the differential gear 117 between a not shown gearbox with the output shaft 114 and a planetary gear reduction 116, 118, 119 is arranged » The transmission shaft 114 is connected to a housing 114a, which includes the differential 117. The housing 114a has an internal toothing 120, by means of which a coupling sleeve 115 is rotatably mounted and longitudinally displaceable on the housing 114a »

The coupling sleeve 115 carries a toothing 120 that matches External toothing 121 and an internal toothing 122 »By moving the sleeve 115 to the left and to the right comes the toothing 122 with an existing on the differential housing 117 External toothing 124 "or with a toothing 123 of the sun gear a 116 in connection. In the former case is the case 114a coupled directly to the differential case 117 =, The Rotation of the hollow shaft 114 is therefore in the ratio lsi to the Housing 117 and thus transferred to the two drive half-shafts 125 and 127.

If the coupling sleeve 115 is shifted to the right from the position shown, the two toothings 122 come into play and 123 meshed with each other = then the sun gear 116 is firmly connected to the hollow shaft 114 and transmits its rotation Via the planet gear 118 and the stationary ring gear 119 into the slow speed on the differential housing 117 connected to the äem Hollow shaft 117a and thus on the drive half-shafts 125 and 127 »

The housing 114a also serves to support a coupling sleeve 130p with which a differential lock-134, 135 is connected = the shift sleeve part 13Q is provided with pins 131, which are in ¹ axial slots 136 of the housing 114a and in axial slots 137 of the. Shift sleeve 115 can move »Δη at their inner end, the pins 131 are connected to a ring 132. which enter openings 135 of a differential bevel gear 128 when the sleeve 130 _{P 133 is moved to the left}

a relative rotation between the housing 114a and the differential housing 117 with part 153 to ₉ if "both parts 114a and 117 have different speeds in the reduced gear" ..

The hollow shaft 117a can be used in a suitable way for the path-dependent drive of a power take-off shaft 106. For this purpose a spur gear 108 is firmly connected to the hollow shaft 117a and in engagement with a further spur gear 10g ₉ which is rotatably mounted on the fixed ring gear 119 * The spur gear 109 drives the PTO shaft 106 depending on the path via a clutch 110 and a pair of bevel gears 111 »
