Abstract
An engine is disclosed having at least one piston in operative connection with a crankshaft. A bearing member which defines an elongated, curved bearing surface, is pivotally attached at one end to an eccentrically-mounted member on the crankshaft. The bearing surface of the bearing member is positioned to be intermittently in power-transmitting, sliding relationship with a connection to the piston such as a piston rod. The bearing member is adapted to be rotatable about said pivotal attachment, for transverse displacement by the piston rod relative to the crankshaft, to absorb any shock generated against the piston and the crankshaft, such as by "engine knock." The bearing member is also adapted to return to its pre-displacement position after absorbing the shock.
Claims16
In an engine having piston means reciprocable in cylinder chamber means, a crankshaft adapted for power-conveying rotation, power-transmitting connection means between said piston means and the crankshaft, and eccentrically-mounted member means mounted on said crankshaft in transverse relation thereto, the improvement comprising, in combination:
- a bearing member pivotally attached to said eccentrically-mounted member means, said bearing member defining an elongated, curved bearing surface, and positioned for sliding, power-transmitting contact with the power-transmitting connection means, whereby, when shock is generated through said power-transmitting connection means, said bearing member can be displaced by pivotal motion to absorb said shock, said bearing member being adapted to return to its pre-displacement position after absorbing of said shock.
In an engine having piston means reciprocable in cylinder chamber means;
- a crankshaft adapted for power conveying rotation;
- power-transmitting connection means between said piston means and the crankshaft, and eccentrically-mounted member means mounted on said crankshaft in transverse relation thereto, the improvement comprising, in combination:
- a bearing member attached to said eccentrically-mounted member means, said bearing member defining an elongated, curved bearing surface, and positioned for sliding, power-transmitting contact with the power-transmitting connection means whereby, when shock is generated through said power-transmitting connection means, said bearing member can be displaced by pivotal motion to absorb said shock, said bearing member being adapted to return to its pre-displacedment position after absorbing of said shock, and spring means positioned adjacent said piston to resiliently bias said piston means away from said bearing member.
In an engine having piston means reciprocable in cylinder chamber means;
- a crankshaft adapted for power-conveying rotation;
- power-transmitting connection means between said piston means and the crankshaft, and eccentrically-mounted member means mounted on said crankshaft in transverse relation thereto, the improvement comprising, in combination:
- a bearing member carried by said eccentrically-mounted member means, said bearing member defining an elongated, curved bearing surface, and positioned for sliding, power-transmitting contact with the power-transmitting connection means, whereby, when shock is generated to said power-transmitting connection means, said bearing member can be displaced to absorb said shock;
- means for biasing said bearing member into its pre-displacement position to cause its return after absorbing of said shock;
- said eccentrically-mounted member means and said bearing member being enclosed in tubular retainer means and capable of rotation therein, said tubular retainer means and eccentrically-mounted member means being positioned in generally co-axial relationship, said tubular retainer means being adapted for colinear, reciprocating motion with said piston means and said connection means, and further defining a transverse tubular sleeve communicating with the interior of said tubular retainer means, said power-transmitting connection means passing through said transverse tubular sleeve for sliding, power-transmitting contact with said bearing member;
- said eccentrically-mounted member means being freely rotatably mounted on said crankshaft, whereby said eccentrically-mounted member means, retained by said tubular retainer means, moves in counterrotating relationship with said crankshaft as the engine operates.
