The assembly to the chassis of a motor vehicle, which facilitates the installation of a probe

摘要

The present invention relates to a group (21) for motor vehicle chassis comprising: - a vehicle floor (22) intended to extend substantially along the vehicle along a longitudinal axis (x), - a tunnel (25) for the passage of an exhaust line provided in the vehicle floor (22) extending along the longitudinal axis (x), - a screen (30) of the thermal protection is intended to be positioned along the exhaust line, and - a probe (31) of the measurement of nitrogen oxides. The assembly (21) also comprises a support (32) carrying the probe (31) is positioned between the screen (30) of the thermal protection and the tunnel (25), so that the screen (30) of the thermal protection and the tunnel (25) delimit a housing (33) for the probe (31) and its support (32).
