Shock absorber assembly
A shock absorber assembly having a wheel assembly including first and second coupling points, and first and second shock absorber elements. Each shock absorber element includes a housing portion defining a bore, and a rod slidably coupled within the bore such that the shock absorber element has a variable length. Each rod is coupled to a respective coupling point of the wheel assembly. The shock absorber assembly is arranged to maintain the relative positions of the first and second housing portions such that the longitudinal axis of the first bore has a generally fixed relationship with respect to the longitudinal axis of the second bore.
1. A shock absorber arranged to be coupled to a vehicle, the shock absorber comprising:
a shock absorber housing defining a linear bore having a non-circular cross section; and
an elongate shock absorber rod slidably coupled within the bore to permit axial movement of the shock absorber rod, the shock absorber rod having a non-circular profile arranged to engage with the bore to inhibit rotation of the rod relative to the housing;
wherein the shock absorber rod is arranged to slide in the bore such that the shock absorber rod can move between an extended condition and a contracted condition relative to the shock absorber housing.
2. A shock absorber assembly according to claim 1 , wherein the bore and/or shock absorber rod have an elliptical or rectangular profile.
3. The shock absorber of claim 1 , further comprising a non-circular seal disposed between the housing and the shock absorber rod.
