  • Patent number: 8556763
    Abstract: A vehicle final reduction gear unit includes a first friction brake positioned between a right case member which is a stationary body and a differential case which is a rotating body for applying a pressing force in an axial direction to generate a frictional force in order to put a brake on the differential case. A second friction brake occupies an area between the differential case and the right wheel and applies a pressing force in the axial direction to generate a frictional force in order to use a rotational difference to put the differential mechanism into a lock state. The second friction brake is placed within the radius of the first friction brake. A reduced size is accomplished and the final reduction gear unit can be reduced in length in the vehicle-transverse direction. Thus, a vehicle final reduction gear unit allowing a reduction in size can be provided.

  • Publication number: 20130000384
    Abstract: Gas pressure in a cavity is detected with a rod-shaped casing that attaches to an hole that opens into the cavity. A porous filter whose top end face matches with a mold cavity face at a top end of the rod-shaped casing separates gas from melt. Cavity gas from an introduction chamber introduces gas through the porous filter, and a gas pressure sensor detects pressure in the chamber. Melt pressure in the cavity is detected with a pressure transmission rod inserted into the rod-shaped casing whose top end face matches with the mold cavity face, and a pressure sensor fixed and held facing a rear end of the pressure transmission rod detects the cavity melt pressure. Cavity melt temperature is detected with a temperature sensor attached to a thin hole formed at the pressure transmission rod's center and includes a thermocouple at a top end part side of the hole.
