Abstract
A hydraulic shock absorber for vehicles wherein an elastic body tightens the outer periphery of piston rod so that the piston rod floats, and noises and vibrations are reduced to be as low as possible.
Claims17
A hydraulic shock absorber for a vehicle, comprising:
- a cylinder having at least a portion thereof supported by a wheel of said vehicle;
- a piston slidably disposed in said cylinder;
- a hydraulic pressure chamber disposed in said cylinder between at least one end of said piston and a closed portion of said cylinder;
- a piston rod movable with said piston and extending out of at least one end of said cylinder;
- said piston rod having at least a portion thereof supported by a portion of the body of said vehicle;
- a rod guide disposed between said piston rod and said cylinder to guide said piston rod;
- an elastic body disposed proximal said rod guide for tightening, enclosing, and supporting at least a portion of the outer periphery of said piston rod;
- the respective ends of said cylinder and rod being supported on the wheel side and vehicle body side so that vibrations and shocks from said wheel are absorbed by the oil pressure generated within said cylinder by sliding of said piston including said rod;
- said elastic body being adapted to elastically tighten said outer periphery of said rod so as to enclose, tighten and support the outer peripheral part of said rod;
- an oil seal member being provided above said rod guide around said rod;
- said elastic body being provided between the upper part of said rod guide and the lower part of said oil seal member provided above said rod guide;
- and
- said elastic body being adapted to tightly support said piston rod in a center position with substantially greater elasticity and rigidity than the tightening force of said oil seal member.
