Abstract

A vehicle four-wheel drive system (10) comprises a first axle (12) with two coaxial first axle shafts (12, 12b) carrying two first wheels (13a, 13b) and a second axle (14) with two coaxial second axle shafts (14a, 14b) carrying two second wheels (15, 15b). A first one (12a) of the first axle shafts is directly driven by a first electric motor (16a) via a first gearbox (16b) and, similarly, a first one (14b) of the second axle shafts is directly driven by a second electric motor (17a) via a second gearbox (17b). A first belt-and-pulley drive transmission (18, 20, 21) drives the second one (14a) of the second axle shafts from the first one of the first axle shafts and a second such transmission (19, 20, 21) drives the second one (12b) of the first axle shafts from the first one of the second axle shafts. The wheels (13a, 15b) of the directly driven axle shafts are disposed on one diagonal and the wheels (13b, 15a) of the indirectly driven axle shafts on a second diagonal of the system.

Abstract

A multi-part multiple pole coaxial electrical connector (10) comprising two interengageable bodies (11a, 11b) of electrically insulating material each provided in a zone of engagement thereof with the other body with a coating of electrically conductive material. A first one (11a) of the bodies is formed in its zone of engagement with a sequence of three radially spaced-apart concentric electrically conductive plugs (13a, 13b, 13c) electrically insulated from one another at insertion ends thereof. The second one (11b) of the bodies is formed in its zone of engagement with a sequence of three radially spaced- apart concentric electrically conductive sockets (15a, 15b, 15c) electrically insulated from one another at entrance ends thereof. The centre plug (13a) is engageable with the wall of the centre socket (15a) to provide an electrical connection therewith forming a centre pole and each radially outer plug (13b, 13c) is engageable with and only with a radially outer wall of the corresponding radially outer socket (15b, 15c) to provide an electrical connection therewith forming a respective radially outer pole separated from the or each adjacent pole by an air gap (16).

Abstract

A multi-part connector (10) for component connection in a construction set comprises a drum (11) and at least one annular flange (12) constructed separately from and connectible with the drum to extend around its circumference. The drum is provided on its circumferential surface with at least one set of recesses (12) lying on a circular path around the drum circumference and the flange (12) is provided at its inner circumference with a plurality of projections (14) engageable in at least some of the recesses of the set to detachably connect the flange with the drum. If the drum (11) has several such sets of recesses (13) the flange (12) can be located in variable positions of the drum and/or one or more additional flanges can be fitted to the drum.

Abstract

A connector (10) for component connection in a modular construction set comprises a connection body of electrically insulating, for example plastics, material defining a disc (11) provided on at least one of its sides, preferably each of its sides, with an axial projection (12) having connecting means for selectable mechanical connection of the disc of another such connector in orthogonal relationship or mechanical and electrical connection of at least one other component (20, 30) in axial relationship. Such a component can be a coupling peg (20) or coupling adapter (30), which are preferably electrically conductively connectible with, respectively, an electrically conductive internal surface (17a) and an electrically conductive external surface (17b) of a sleeve (17) located in the axial projection

Abstract

A connector (10) for component connection in a modular construction set comprises a hollow drum portion (11) and a flange portion (12) extending from the circumference of the drum portion, the drum portion having a plurality of equidistantly spaced apertures (14) around its circumference and the connector being provided on the drum portion with a captive locking ring (22) having a respective locking projection (24) extending through each of the apertures and into the interior of the drum portion. The locking ring (22) is rotatable relative to the drum portion (11) between an unlocking position in which at least one of the locking projections (24) is substantially alignable at its underside with a surface of a component, for example an adapter (30), received in the drum portion (11) and a locking position in which that projection is engageable, especially pressurably engageable, with the surface of the component (30) for retention of the component in the drum portion.

Abstract

The invention relates to a construction set made of a plurality of different members interacting together for assembly, characterised in that one so-called connector member (100) among said members has an essentially cylindrical body with a cylindrical surface (110) that is preformed in order to interact for assembly with the correspondingly preformed bases (120, 130) of other connector members (100'). The construction set includes a plurality of other constitutive members.
