Abrégé

The invention relates to a mecanum-wheeled vehicle (1), in particular for transporting a payload, comprising a chassis (5) which extends along a longitudinal axis (L) and a transverse axis (B) running perpendicular to the longitudinal axis and which includes at least four mecanum wheel drives (2; 2a to 2d) that can be controlled by control means (13) in such a way that the mecanum-wheeled vehicle (1) can be operated omnidirectionally. According to the invention, the chassis (5) has a first chassis section (21a) comprising at least two (2a, 2b) of the mecanum wheel drives (2; 2a, 2b, 2c, 2d), and a second chassis section (21b) comprising at least two of the mecanum wheel drives (2; 2a, 2b, 2c, 2d); furthermore, the first and second chassis sections (21a, 21b) are mechanically interlinked in such a way that the distance therebetween can be varied, and the mecanum-wheeled vehicle (1) includes sensor means (24) for measuring at least one dimension, in particular a width and/or a length, of a payload (10) to be held by the mecanum-wheeled vehicle (1), the sensor means (24) being connected in a signal-conducting manner to the control means (13); and finally, the distance between the first and second chassis sections (21a, 21b) along a first adjustment axis (E1) can be adjusted by having the control means (13) control at least one of the mecanum wheel drives (2; 2a, 2b, 2c, 2d) in the first chassis section (21a) and/or the second chassis section (21b) in accordance with the at least one payload dimension measured by the sensor means (24).

The invention relates to a mecanum-wheeled vehicle (1), in particular for transporting a load, comprising a chassis (5) extending along a longitudinal axis (L) and a width axis (B) oriented perpendicular to the same, said chassis comprising at least four mecanum wheel drives (2; 2a to 2d) which can be controlled via control means (13) for carrying out an omnidirectional operation of the mecanum-wheeled vehicle (1), wherein the chassis (5) has a first chassis section (21a) with at least two (2a, 2b) of the mecanum wheel drives (2; 2a, 2b, 2c, 2d) and a second chassis section (21b) with at least two (2c, 2d) of the mecanum wheel drives (2; 2a, 2b, 2c, 2d). According to the invention, the first and the second chassis sections (21a, 21b) are arranged adjacent along a first adjustment axis (E1) and are mechanically connected to one another such that the spacing between same can be varied, and the spacing between the first and second chassis sections (21a, 21b) is adjustable along a first adjustment axis (E1) by controlling at least one of the mecanum wheel drives (2; 2a, 2b, 2c, 2d) of the first chassis section (21a) and/or of the second chassis section (21b) by means of the control means (13).

Abrégé

The invention relates to a Mecanum wheel having a first wheel rim (2) which bears a multiplicity of rollers (4) which are arranged adjacent to one another in a circumferential direction and which are in each case mounted so as to be rotatable about a roller axis of rotation (38) arranged at an angle with respect to a first wheel rim axis of rotation (24), wherein said Mecanum wheel is characterized by a second wheel rim (3) which can be driven together with the first wheel rim (2) by means of a common drive shaft (33) and which bears a multiplicity of rollers (4) which are arranged adjacent to one another in a circumferential direction and which are in each case mounted so as to be rotatable about a roller axis of rotation (38) arranged at an angle with respect to a second wheel rim axis of rotation (25), which second wheel rim is connected to the first wheel rim (2) via damping means (7) formed so as to permit a limited relative movement of the first and the second rim (3) relative to one another. It is provided according to the invention that the damping means (7) are formed so as to permit a damped, limited relative movement between the first and the second wheel rim (2, 3) in the circumferential direction and/or perpendicular to a Mecanum wheel axis of rotation (9) and/or perpendicular to the first and/or to the second wheel rim axis of rotation (25) and/or at a tilt angle relative to one another.
