专利汇可以提供Safety housing专利检索，专利查询，专利分析的服务。并且This invention includes a bell housing and a deflector plate which is connected to and which covers the open end of the bell housing to form, in combination, a safety housing for containing, inter alia, flywheel fragments. The safety housing substantially encloses both a clutch assembly and a flywheel which is carried on a crankshaft extending through the deflector plate and is connected at its forward end to an engine block and at its rearward end to a transmission housing. The bell housing is formed from a high ductile metal and the deflector plate is formed from a metal of medium ductility. The bolts used to interconnect them are formed from a high tensile and, preferably, low ductile metal so that deformation of the bell housing causes similar deformation of the deflector plate. Attachment of the safety housing to the engine block is preferably by soft metal bolts.，下面是Safety housing专利的具体信息内容。

权利要求

1. A vehicle safety housing for mounting between an engine block and a transmission, comprising: a bell Housing sized to accommodate a flywheel and a clutch assembly and having an open end disposed toward said engine block, said bell housing formed from a high ductile metal having an elongation greater than about 30 percent (70* F) to substantially absorb the energy of flywheel and clutch assembly fragments and to substantially prevent the escape of said fragments therethrough; a deflector plate disposed between said engine block and said bell housing and sized to cover said open end of said bell housing, said deflector plate formed from a medium ductile metal having an elongation between about 25 percent and about 28 percent (70* F); and tie bolt means for interconnecting said bell housing and said deflector plate, said tie bolt means formed from a high tensile strength metal to substantially resist shearing of said tie bolt means upon attempted separation of said bell housing and said deflector plate from each other.

2. The safety housing of claim 1 wherein said high ductile metal of said bell housing is a low carbon steel selected from the group consisting of 1004, 1006 and 1008 (AISI designation) steel.

3. The safety housing of claim 2 wherein said medium ductile metal is a steel selected from the group consisting of 1015, 1020 and 1025 hot-rolled standard steel (AISI designation).

4. The safety housing of claim 1 wherein said high tensile metal has low ductility so that separation of said bell housing from said deflector plate is substantially prevented.

5. The safety housing of claim 4 wherein said high tensile, low ductile metal is a Grade 8 steel.

6. The safety housing of claim 5 wherein said steel is 4130 Cr-Mo steel.

7. The safety housing of claim 1 including, in addition, block bolt means for connecting said bell housing and said deflector plate to said engine block, said block bolt means formed of a soft metal which elongates if said deflector plate is caused to separate from said engine block to thereby prevent said engine block from warping.

8. A safety housing for mounting between an engine block and a transmission, comprising: a bell housing sized to accommodate a flywheel and a clutch assembly and having an open end disposed toward said engine block, said bell housing formed from a steel selected from the group consisting of 1004, 1006 and 1008 steel (AISI) having an elongation between about 30 percent and about 36 percent (70* F); a deflector plate disposed between said bell housing and said engine block and sized to cover said open end of said bell housing, said deflector plate formed from a steel selected from the group consisting of 1015, 1020 and 1025 hot-rolled standard steel having an elongation between about 28 percent and about 25 percent; and tie bolt means for interconnecting said bell housing and said deflector plate, said tie bolt means formed from a high tensile, low ductile metal to substantially prevent separation of said bell housing and deflector plate from each other.

9. The safety housing of claim 8 including block bolt means of a soft, Grade 1 steel for connecting said bell housing and said deflector plate to said engine block.

10. The safety housing of claim 8 wherein said high tensile, low ductile steel is 4130 Cr-Mo steel.
