Abstract

An additional wheel weight for a utility vehicle includes a weight plate and a retention member configured to be fitted to a wheel and on which the weight plate is guided in a longitudinally axial manner. A clamping lever closure is disposed between the weight plate and retention member. A first assembly element of the clamping lever closure is coupled to the retention member, a second assembly element of the clamping lever closure engages the weight plate in a longitudinally axial manner, and a lever mechanism is disposed between the first and second assembly elements. The lever mechanism includes a clamping element being releasably secured to the first assembly element and an actuation lever being articulated between the second assembly element and the clamping element.

First claim

The invention claimed is:

1. An additional wheel weight for a utility vehicle, comprising:
a weight plate and a retention member configured to be fitted to a wheel and on which the weight plate is guided in a longitudinally axial manner;
a clamping lever closure disposed between the weight plate and retention member, the clamping lever closure being operable manually or via an external force;
a first assembly element of the clamping lever closure coupled to the retention member;
a second assembly element of the clamping lever closure engaging the weight plate in a longitudinally axial manner;
a lever mechanism disposed between the first and second assembly elements, the lever mechanism comprising a clamping element being releasably secured to the first assembly element and an actuation lever being articulated between the second assembly element and the clamping element;
wherein, a pivotal movement of the actuation lever between an open position and a closed position induces a reduction of a longitudinally axial spacing between the first and second assembly elements in order to clamp the weight plate with respect to the retention member;
wherein the retention member comprises a hollow-cylindrical base member and a securing crown which the retention member is screwed to the wheel using one or more bolts.

2. The additional wheel weight of claim 1 , wherein the first assembly element comprises two opposing assembly walls through which a clamping bolt is guided in a transversely axial manner.

3. The additional wheel weight of claim 2 , wherein the clamping element comprises an assembly hook disposed in engagement with the clamping bolt.

4. The additional wheel weight of claim 1 , wherein the lever mechanism is securely disposed in the closed position by a securing element.

5. The additional wheel weight of claim 1 , further comprising longitudinal ribs formed on the base member for reducing a frictional force between the weight plate and the base member during assembly.

6. The additional wheel weight of claim 1 , wherein the actuation lever comprises a receiving member for an actuation tool, the actuation lever being pivotal between the open and the closed positions via the receiving member.

7. An agricultural working vehicle, comprising:
a chassis having at least one axle;
an additional wheel weight disposed on the axle, the additional wheel weight comprising:
at least one weight plate and a retention member configured to be fitted to a wheel and on which the at least one weight plate is guided in a longitudinally axial manner;
a clamping lever closure disposed between the at least one weight plate and retention member, the clamping lever closure being operable manually or via an external force;
a first assembly element of the clamping lever closure coupled to the retention member;
a second assembly element of the clamping lever closure engaging the at least one weight plate in a longitudinally axial manner; and
a lever mechanism disposed between the first and second assembly elements, the lever mechanism comprising a clamping element being releasably secured to the first assembly element and an actuation lever being articulated between the second assembly element and the clamping element;
wherein, a pivotal movement of the actuation lever between an open position and a closed position induces a reduction of a longitudinally axial spacing between the first and second assembly elements in order to clamp the at least one weight plate with respect to the retention member;
wherein the retention member comprises a hollow-cylindrical base member and a securing crown which the retention member is screwed to the wheel using one or more bolts.

8. The vehicle of claim 7 , wherein the first assembly element comprises two opposing assembly walls through which a clamping bolt is guided in a transversely axial manner.

9. The vehicle of claim 8 , wherein the clamping element comprises an assembly hook disposed in engagement with the clamping bolt.

10. The vehicle of claim 7 , wherein the lever mechanism is securely disposed in the closed position by a securing element.

11. The vehicle of claim 7 , further comprising longitudinal ribs formed on a base member for reducing a frictional force between the at least one weight plate and the base member during assembly.

12. The vehicle of claim 7 , wherein the actuation lever comprises a receiving member for an actuation tool, the actuation lever being pivotal between the open and the closed positions via the receiving member.

13. An additional wheel weight for a utility vehicle, comprising:
a first weight plate, a second weight plate, and a retention member configured to be fitted to a wheel and on which the first and second weight plates are guided in a longitudinally axial manner;
a clamping lever closure disposed between the first and second weight plates and retention member, the clamping lever closure being operable manually or via an external force;
a first assembly element of the clamping lever closure coupled to the retention member;
a second assembly element of the clamping lever closure engaging the first and second weight plates in a longitudinally axial manner;
a lever mechanism disposed between the first and second assembly elements, the lever mechanism comprising a clamping element being releasably secured to the first assembly element and an actuation lever being articulated between the second assembly element and the clamping element;
wherein, a pivotal movement of the actuation lever between an open position and a closed position induces a reduction of a longitudinally axial spacing between the first and second assembly elements in order to clamp the first and second weight plates with respect to the retention member;
wherein the retention member comprises a hollow-cylindrical base member and a securing crown which the retention member is screwed to the wheel using one or more bolts.

14. The additional wheel weight of claim 13 , wherein the first assembly element comprises two opposing assembly walls through which a clamping bolt is guided in a transversely axial manner.

15. The additional wheel weight of claim 14 , wherein the clamping element comprises an assembly hook disposed in engagement with the clamping bolt.

16. The additional wheel weight of claim 13 , wherein the lever mechanism is securely disposed in the closed position by a securing element.

17. The additional wheel weight of claim 13 , wherein the actuation lever comprises a receiving member for an actuation tool, the actuation lever being pivotal between the open and the closed positions via the receiving member.

18. The additional wheel weight of claim 13 , further comprising longitudinal ribs formed on the base member for reducing a frictional force between the first and second weight plates and the base member during assembly.
