A control arm assembly for a suspension system of a vehicle includes a control arm having a triangular shape for connection to vehicle structure and a beam axle of the vehicle. The control arm assembly also includes a plurality of bushings connected to the control arm and for connection to the vehicle structure and the beam axle of the vehicle.

Suspension control arm assembly for vehicles

A tire pressure monitoring system for a vehicle with at least one tire includes at least one pressure sensor adapted for sensing pressure inside the at least one tire. The system also includes at least one indicator adapted to communicate a stop signal indicating that pressure inside the at least one tire is equal to a target pressure. The indicator is also adapted to communicate a continue signal indicating that pressure inside the at least one tire is unequal to a target pressure. The continue signal is adapted to indicate how close the pressure inside the at least one tire is to the target pressure. The tire pressure monitoring system further includes a controller in communication with the at least one pressure sensor and the at least one indicator. The controller is adapted to determine the target pressure according to a predicted operating condition of the at least one tire.

Tire pressure monitoring system and method therefor

A method for hydroforming a tubular structural member of generally polygonal, flat walled cross section in which the various walls in the final part do not have the same thickness. A cylindrical tubular blank is extruded in which the outer surface is round, but in which the inner surface is asymmetrical, providing several contiguous angular sectors or portions of varying width and thickness. Each individual angular portion is tailored as to thickness and width to correspond to a respective wall in the final part. The blank is oriented between in a die cavity so as to align each angular portion with a respective wall of the finished part, and hydroformed in conventional fashion.
