Road traction apparatus

摘要

Aspects of the present invention disclose an apparatus for increasing roadway traction. An exemplary apparatus includes a housing and a shaft that engages a first end of the housing. A piston is adapted to move axially along a length of housing and includes an upper portion and lower portion. The upper portion includes a raised surface and a mating portion situated between the raised surface and lower portion. The lower portion includes an interior cavity that is adapted to receive at least a portion of the shaft. A spring that biases the piston toward the first end of the housing. A toothed surface engaged with the piston and a bimetal thermostat with a mating toothed surface. The toothed surface engaged with the lower portion facilitates engagement with the mating toothed surface situated at the distal end of the bimetal thermostat when the temperature is above a predetermined threshold.
