Abstract
A ground connection for a vehicle comprising a wheel (1), a sliding suspension for a wheel carrier relative to a support (10) connected to the vehicle, the suspension comprising a substantially vertical pillar (8) fixed to the wheel carrier, the degree of freedom of suspension of the wheel carrier relative to the support (10) being permitted by the movement of the pillar in the guide means (11) connected to the support, means for driving the wheel by a first rotary electric machine (15) mounted in the wheel, the first electric machine driving the wheel by means of reversible reduction means, the reduction means comprising a ring gear (16) fixed to the wheel and a drive pinion (17) connected to the first machine and defining a reduction ratio between the speed of rotation of the first machine and the speed of rotation of the wheel, the reduction ratio being greater than 10, said ground connection having no mechanical service brake.
