Abstract
A suspension travel control system (1046) for a vehicle suspension is disclosed. The suspension travel control system includes a stop post (834) secured to the vehicle frame and a suspension travel control formation that includes a base (1042) and a body (1048). The stop post (834) is positioned in a space defined by the body (1048). The suspension travel control formation may be secured to the axle, the main support member or incorporated into the axle coupling assembly to provide a rebound and jounce stop as well as longitudinal redundancy in the event of the failure or loss of a longitudinal linkage.
Claims32
A suspension system for a vehicle having a vehicle frame, comprising,
- an axle;
- a suspension linkage, said suspension linkage being longitudinally disposed and for movable connection to the vehicle frame;
- a suspension travel control system comprising
- a stop post to be secured at one end to the vehicle frame and presenting at least one contact surface, and
- a suspension travel control formation comprising a body and a base, the body having an interior surface defining an elongated interior space, the body being a rigid structure that moves in relation to the stop post during operation of the suspension system,
- wherein each of the body and the base of the suspension travel control formation presents a first engagement surface positioned and arranged for contact with one another to assist in securing the body to the base,
- wherein the axle, the suspension linkage, and the suspension travel control formation are fixed in relation to one another and undergo generally vertical suspension travel movement relative to said stop post during operation of the suspension system, with the stop post in the interior space of the suspension travel control formation body, and
- wherein the stop post is positioned in the interior space for the engagement of the at least one contact surface of the stop post with the interior surface of the body to limit downward travel of the axle or the suspension linkage during operation of the suspension system.
A suspension travel control system for a suspension system of a vehicle, said suspension travel control system comprising,
- a stop post configured for securement at one end to a vehicle frame and presenting at least one contact surface, and
- a suspension travel control formation comprising a body and a base, the body having an interior surface defining an elongated interior space, the body being a rigid structure that moves in relation to the stop post during operation of the suspension system,
- wherein the suspension travel control formation is configured for fixed securement to an axle and a suspension linkage of the vehicle, the axle the suspension linkage and the suspension travel control formation further configured to undergo generally vertical suspension travel movement relative to said stop post during operation of the suspension system with the stop post positioned in the interior space of the suspension travel control formation body for the engagement of the at least one contact surface of the stop post with the interior surface of the body to limit downward travel of the axle or the suspension linkage during operation of the suspension system.
