Abstract
A torsion system (20) comprising a housing (24) adapted to be secured to a structural portion of a vehicle. A shaft (23) has a core portion (32) accommodated in the housing (24) and defines concavities (34) in the core portion (32). The shaft (23) has a connector end (30) connected to a crank arm. The connector end (30) protrudes out of the housing (24). Elastomeric members (25,25′) are received in the concavities (34) of the shaft (23). The elastomeric members (25,25) each have a geometry so as to at least partially fill the concavities (34) and contact an inner surface of the housing (24), whereby a rotation of the crank arm results in a deformation of the elastomeric members (25,25′).
Claims16
A torsion system comprising:
- a housing adapted to be secured to a structural portion of a vehicle;
- a shaft having a core portion accommodated in the housing and defining at least one concavity in the core portion, the shaft having a connector end connected to a crank arm, the connector end protruding out of the housing;
- and
- at least one elastomeric member received in the concavity of the shaft, the elastomeric member having a geometry so as to at least partially fill the concavity and contact an inner surface of the housing;
- whereby a rotation of the crank arm results in a deformation of the elastomeric member.
A method for inserting elastomeric members in a torsion system, comprising the steps of:
- positioning at least one unused elastomeric member on a shaft of a torsion system;
- manually inserting the shaft and the at least one unused elastomeric member in a housing of the torsion system;
- and
- locking support blocks to maintain the shaft and elastomeric member captive in the housing of the torsion system.
