A wheel connecting assembly for an automobile which includes a wheel carrier and a support having a guide member for guiding the wheel carrier in translational movement relative to the support. The support has journals for mounting the support on the chassis of a vehicle. The wheel carrier is mounted on the guide member by means of a bar sliding in the guide member. The assembly includes a spring and an electromechanical device capable of being operated in order to control the deflecting movements of the suspension.

Each support (5) is mounted on the chassis (1) by means of a camber mechanism which includes a camber lever (4) and an actuating lever (40) making it possible to vary the camber angle of the corresponding wheel (2). The camber mechanism includes an arm (70) mounted on the support (5) on an axis of support oriented substantially parallel to the longitudinal plane, and mounted on the chassis (1) without any possibility of tilting about a longitudinal axis relative to the chassis (1), so as to transmit the weight carried by the chassis to the support (5).

Abstract:
A mold for molding and vulcanizing a rubber tire comprises a rigid core defining an interior surface of the tire, two side parts and a peripheral ring divided into a plurality of segments. In order to be able to close the mold, all the members are designed to slide on each other during final phase of their closing movement.
Abstract:
A vehicle steering control system includes a controller for determining control angles for actuators used for steering the vehicle based on at least a speed of the vehicle and a steering signal. The controller includes a unit, a module, and a block. The unit determines an equivalent steering angle of a steered wheel of an equivalent bicycle model according to the steering signal, and also determines a transverse coordinate of an instantaneous center of rotation of the vehicle. The module controls a steering behaviour of the vehicle to enable a longitudinal coordinate of the instantaneous center of rotation of the vehicle to be determined from the speed of the vehicle and a maximum transverse acceleration parameter of the vehicle. The block determines the control angles from the longitudinal coordinate and the transverse coordinate. The maximum transverse acceleration parameter of the vehicle is fixed for the vehicle or is variable based on conditions of operation of the vehicle.
