Abstract

This patent discloses a shield for an automatic transmission used in race cars radial that includes a strengthened fluid pan and a formed metal jacket shield that extends around the section of the housing of the transmission adjacent to the fluid pan from opposite sides of the fluid pan. The strengthened fluid pan is constructed to extend outwardly from the transmission housing to provide locations at which the jacket shield may be secured to the fluid pan and to increase the volume of the fluid pan as compared to conventional fluid pans. The jacket shield is secured directly to the fluid pan and in combination with the fluid pan provides a shield that continuously surrounds the transmission and resists perforation and separation due to impact of fragments propelled from the transmission after breakage of rotating components of the transmission.

Dependent claims

A shield in combination with an automatic transmission having a housing including a pan mounting section adjacent to transmission components rotating about a transmission axis comprising:

a fluid plan constructed to remain imperforate after impact by fragments created by failure of the rotating transmission components and being mounted to the pan mounting section;
a jacket constructed to remain imperforate after impact by fragments created by failure of the rotating transmission components and formed to radially surround a section of the housing adjacent to the rotating transmission components and secured to the fluid pan;
and
the jacket being fastened directly to the fluid pan to maintain attachment of the jacket to the fluid pan during and after impact of the shield by fragments created by failure of the rotating transmission components, the jackets being secured to the housing indirectly by attachment to the fluid pan which fluid pan is then fixedly connected to the pan mounting section of the housing and thereby the jacket and fluid pan provide a continuous shield that radially surrounds the rotating transmission components that withstands penetration by fragments created by failure of the rotating transmission components, and withstand separation of the fluid pan and the jacket due to impact by fragments created by failure of the rotating transmission components.
