[0001] The present disclosure relates to a structure of a shock absorber cap for a vehicle suspension system fitted on top of a piston rod of the vehicle suspension system. The structure of the shock absorber cap is designed for better fitment and noise reduction inside the passenger cabin of the vehicle.
BACKGROUND
[0002] A shock absorber cap is mounted above the shock absorber of a vehicle suspension system. The shock absorber cap is used to isolate the operating noise of the shock absorber from the passenger compartment of the vehicle. The shock absorber cap has bellows that compress and expands during shock absorber stroke. Further, internal threads are provided on the shock absorber cap for locking with external threads of a piston rod of the shock absorber.
[0003] FIG. 1A illustrates a conventional or existing shock absorber cap 101. FIG. 1B illustrates a sectional view of the shock absorber cap 101 fitted inside vehicle body 104. The shock absorber cap 101 has bellows 103. Further, internal threads are provided on an inner layer of the shock absorber cap 101 for locking with external threads of a piston rod 105. As discussed above, the shock absorber cap 101 is mounted above a shock absorber and is used to isolate operating noise, however, during vehicle running conditions, at bumps, due to compression of the shock absorber cap 101, noise is generated due to touching between a bush 107 and the bellows 103 of the shock absorber cap 101. Further, although, internal threads are provided on the shock absorber cap 101 (rubber part) for locking with external threads of the piston rod 105 (metal part), there is a possibility of shock absorber cap 101 removal.
[0004] In view of the above, there is a need to provide a solution that eliminates the noise that is generated because of touching between the bush 107 and bellows 103 of the shock absorber cap 101 and also minimizes the chance of removal of the shock absorber cap 101.

[00032] FIG. 2A illustrates a shock absorber cap 201 as per an embodiment of the present disclosure. Fig. 2B illustrates a sectional view of the shock absorber cap 201 with a vehicle body when installed in a vehicle. The shock absorber cap 201 comprises a cylindrical side wall 202 and a top surface 203. In an aspect, the top surface 203 is a flat surface or a curved surface. Further, an inner cylindrical wall 213 protrudes downwards from the edges of the top surface 203. The cylindrical side wall 202 has varying diameter along the height, and the diameter of the cylindrical side wall 202 increases towards downward from the top surface 203.
[00033] Further, the shock absorber cap 201 comprises bellows 205 formed on an area of the cylindrical side wall 202 above shock absorber bush 211. Thus, in the shock absorber cap 201 as illustrated in Fig 2B, bellows 205 of the shock absorber cap 201 is shifted upwards, i.e., on the area of the cylindrical side wall 202 above shock absorber bush 211 and an inner diameter (ID) at the lower portion of the shock absorber cap near the shock absorber bush 211 is having inner diameter more than maximum outer diameter of the bush 211 so as to avoid contact of lower portion of shock absorber cap 201 with the bush 211 and negate noise generation. Further, the thickness of the lower portion of the shock absorber cap 201 is reduced to provide noise sealing with the vehicle body.
[00034] Further, the shock absorber cap 201 comprises an inner cylindrical wall 213 protruding from the top surface 203. The inner cylindrical wall 213 comprises threads 215 on its inner side for locking the shock absorber cap 201 with external threads 217 of a piston rod 209 over which the shock absorber cap 201 is mounted. Further, the shock absorber cap 201 comprises a lug 207 extending perpendicular from a center of an inner side of the top surface 203. The lug 207 is provided for locking on slot provided on top of the piston rod 209 thereby providing better fitment and minimize the chance of removal of the shock absorber cap 201. In an aspect, the shock absorber cap 201 is made from an elastomeric material.
[00035] In an aspect, the shock absorber cap 201 is mounted on piston rod of shock absorber of front suspension system of vehicle.
[00036] In another aspect, the shock absorber cap 201 is mounted on piston rod of shock absorber of rear suspension system of vehicle.
