Ball-type coupling arrangement for an agricultural tractor
A ball-type coupling arrangement for an agricultural tractor including a coupling base with a coupling ball attached thereto for receiving a coupling socket, a coupling housing arranged on the coupling base, a hold-down device including a planar stop region formed on an outer contour, the hold-down device coupled to the coupling housing such that it is pivotable between a position locking the coupling ball and a position releasing the coupling ball, and a closure element attached to the coupling housing, the closure element contacting the planar stop region in a locking position to lock the hold-down device in its locking position.
1 . A ball-type coupling arrangement for an agricultural tractor, comprising:
a coupling base with a coupling ball attached thereto for receiving a coupling socket;
a coupling housing arranged on the coupling base;
a hold-down device including a planar stop region formed on an outer contour, the hold-down device coupled to the coupling housing such that it is pivotable between a position locking the coupling ball and a position releasing the coupling ball; and
a closure element attached to the coupling housing, the closure element contacting the planar stop region in a locking position to lock the hold-down device in its locking position;
wherein the closure element is formed as a transverse latch extending in a locking position perpendicular to the pivoting direction of the hold-down device on the coupling housing, the transverse latch can be secured in the locking position via a manually actuable securing mechanism, which includes a spring-pretensioned securing bolt having a free end engaging in a recess formed in the transverse latch in the locking position.
2 . The ball-type coupling arrangement of claim 1 , wherein the transverse latch is coupled to the coupling housing such that it can be pivoted manually into a position releasing the locking of the hold-down device.
3 . The ball-type coupling arrangement of claim 1 , wherein the planar stop region is oriented radially with respect to a point of rotation serving for coupling the hold-down device to the coupling housing.
4 . The ball-type coupling arrangement according of claim 1 , wherein the transverse latch has a coupling region for the rotatable mounting on the coupling housing, and the transverse latch has a gripping region at a free end opposite the coupling region.
5 . The ball-type coupling arrangement of claim 4 , wherein a protrusion extending over the coupling region in the opposite direction to the free end is provided on the transverse latch.
6 . The ball-type coupling arrangement of claim 1 , wherein the recess is contoured along an entry region in such a manner that a snap-action closure is formed in interaction with the free end of the spring-pretensioned securing bolt.
7 . The ball-type coupling arrangement of claim 1 , wherein the hold-down device is pretensioned via a spring element in the direction of the position releasing the coupling ball.
8 . An agricultural tractor including a ball-type coupling arrangement, comprising:
a coupling base with a coupling ball attached thereto for receiving a coupling socket;
a coupling housing arranged on the coupling base;
a hold-down device including a planar stop region formed on an outer contour, the hold-down device coupled to the coupling housing such that it is pivotable between a position locking the coupling ball and a position releasing the coupling ball; and
a closure element attached to the coupling housing, the closure element contacting the planar stop region in a locking position to lock the hold-down device in its locking position, the closure element is formed as a transverse latch extending in a locking position perpendicular to the pivoting direction of the hold-down device on the coupling housing, and the transverse latch being secured in the locking position via a manually actuable securing mechanism, which includes a spring-pretensioned securing bolt having a free end engaging in a recess formed in the transverse latch in the locking position.
9 . The agricultural tractor of claim 8 , wherein the transverse latch is coupled to the coupling housing such that it can be pivoted manually into a position releasing the locking of the hold-down device.
10 . The agricultural tractor of claim 8 , wherein the planar stop region is oriented radially with respect to a point of rotation serving for coupling the hold-down device to the coupling housing.
11 . The agricultural tractor according of claim 8 , wherein the transverse latch has a coupling region for the rotatable mounting on the coupling housing, and the transverse latch has a gripping region at a free end opposite the coupling region.
12 . The agricultural tractor of claim 11 , wherein a protrusion extending over the coupling region in the opposite direction to the free end is provided on the transverse latch.
13 . The agricultural tractor of claim 8 , wherein the recess is contoured along an entry region in such a manner that a snap-action closure is formed in interaction with the free end of the spring-pretensioned securing bolt.
14 . The agricultural tractor of claim 8 , wherein the hold-down device is pretensioned via a spring element in the direction of the position releasing the coupling ball.
