Abstract

PROBLEM TO BE SOLVED: To incline an upper sheet in the opposite direction to the acting direction of lateral force, so as to reduce lateral force to act on a compression coil spring, by pinching spacers having the different heights between an upper support fixed to an absorber rod and the upper sheet with which the upper end of the compression coil spring is to be brought in contact. SOLUTION: In a shock absorber 1, an absorber tube 2 is connected to a lower arm for supporting a wheel, an absorber rod 3 is attached to a flange (d) of a vehicle body, and a compression coil spring 14 is mounted between a lower sheet fixed to the absorber tube 2 and an upper sheet 7. In this case, three adjusting bolts 5 whose spherical head parts 6 as spacers face downward are inserted into the upper support 4 at equal distances, and the projecting amount is adjusted by nuts 8 so that the upper sheet 7 may be inclined at appropriate angles and in the appropriate direction. Vibrationproof rubbers 12, 13 are fixed to the upper sheet 7 and the upper support 4, and therefore, vibration can be absorbed.

それがある。2. Description of the Related Art In recent years, the design stress of suspension coil springs has increased and the pitch angle has increased due to the practical use of high-strength spring steel and the improvement of processing techniques such as special shot peening in order to reduce the weight and size. As a result, lateral force acts even in the case of parallel compression that displaces the spring seat only in the direction of the coil axis, and when extrapolated to the shock absorber, the lateral force causes twisting between the absorber rod and the absorber tube, Riding comfort may be degraded and the life of the absorber may be shortened.

Since the upper sheet is tilted with respect to the absorber rod with spacers with different heights interposed therebetween, the lateral force acting on the compression coil spring can be reduced by tilting the upper sheet in the direction opposite to the direction of the lateral force. Thus, the ride comfort can be improved and the life of the shock absorber can be prolonged. Since the configuration is a bolt, there is an effect that the inclination of the upper sheet can be appropriately adjusted, and The invention according to claim 3, characterized in that in the invention of claim 1, since the spacer has a structure which is integral body,
There is an effect that the lateral force can be easily reduced by replacing the spacer.
