The supporting frame comprises a first pair of supports, a second pair of supports, and at least one third pair of supports for a motor-vehicle bodyshell, wherein the second pair and the third pair are configured for co-operating alternatively with the first pair for supporting a motor-vehicle bodyshell received on the frame.

Abstract: A holding device to hold a tube or cable in engagement with a bracket is provided with a structure having a seat, which is a through seat along an axis and is defined by a substantially C-shaped edge so as to have a radial opening; the structure further has a slit, which extends along a radial direction up to said seat so as to allow the bracket, in use, to be inserted into the slit and engage the seat; the holding device is further provided with a wing, which is movable between an open position, in which the seat can be accessed through the opening and a closed configuration, in which the opening is closed by the wing.

Abstract: A manufacturing process for making different expansion tanks for different cooling systems and/or for different engines, each of the expansion tanks having an inlet mouth and comprising: a plastic shell comprising a) a wall defining a cavity for containing a coolant liquid; and b) at least one collar at the inlet mouth, the collar being outwardly projecting from the wall. Each of the expansion tanks further comprising a tubular insert engaging the collar and defining the inlet mouth; the tubular insert being made of plastic material; and retention means which hold the tubular insert relative to the collar.

Abstract: A brake disc for motor-vehicle disc brakes, includes a body with a hub and two opposite annular planar faces, wherein at least one of these faces is formed with one or more lines defining a surface irregularity, in the form of grooves or ribs, which extend between a radially inner edge and a radially outer edge of the respective face, so as to substantially cover the entire radial extension of the face. A height of the surface irregularity along said lines is less than 0.30 mm, so that during use, the lines defining the surface irregularity disappear, due to wear of the respective face, after an initial fraction of the life of the brake disc. During this initial stage, the lines defining the surface irregularity reduce the time necessary to obtain a bedding of the disc brake with respect to a case of a brake disc devoid of the lines.

Abstract: A device for controlling a gearbox includes a transmission member that transmits movement of a control lever to a control cable. A locking member, having a first and second portions for locking the lever in respective park and neutral positions, is mounted in a device casing. An actuator causes the locking member to rotate when the lever must be unlocked from park position and when the lever must be locked in neutral position. The device includes an anti-locking pawl mounted on the transmission member, having an operative position preventing the second portion from being received in a transmission member seat for locking the lever in the neutral position. If the lever is freed from park position and moved through the neutral position while the actuator is active, the pawl is pushed by the locking member into its operative position, thereby preventing unwanted locking of the lever in the neutral position.

Abstract: Described is a device for synchronization of a reverse gear for a vehicle gearbox including: a support shaft fixed in rotation; an idle gear wheel for engagement with a first reverse gear wheel on a gearbox primary shaft and a second reverse gear wheel on a gearbox secondary shaft, said idle gear wheel mounted rotatable and axially slidable on said support shaft and having a hub including a first friction surface; and a synchronizer ring mounted mobile on said support shaft along an axial travel and countered axially by an elastic element along said axial travel, said synchronizer ring having a second friction surface for engagement with said first friction surface. Axial movement of the idle gear wheel towards an engagement position of the reverse gear causes drawing of the synchronizer ring implementing, prior to reverse gear engagement, braking of rotary movement of the idle gear wheel.

Abstract: A diesel engine system includes a diesel engine, an exhaust line, a particulate filter interposed in the exhaust line and an electronic control unit for controlling fuel injectors associated with cylinders of the engine. When an accumulated particulate mass in said filter reaches a predetermined threshold, a filter regeneration mode is activated, including activating post-injections of fuel by controlling said injectors, to determine a start of an automatic filter regeneration step, which is caused by an increase in temperature of exhaust gases fed to the filter. The temperature increase is sufficient to burn particulate in the filter. The post-injections of fuel are deactivated whenever a critical condition occurs for at least a first period of time, the critical condition being one in which a temperature value upstream of the filter exceeds a first threshold value. In this case, the regeneration mode is resumed following disappearance of the critical condition.
