A bracket assembly for a multi-link suspension system is provided, said bracket assembly mounted to a housing of an automotive vehicle, as opposed to a chassis of the automotive vehicle, enabling modularity and ease of replacement of the housing and adjustability of suspensions system components. The bracket assembly may have a body, wherein the body includes: an axle tube hole; one or more cross tube support holes; at least one trailing arm attachment portion having a first plurality of adjustment holes and a second plurality of adjustment holes; an anti-roll bar attachment portion having one or more attachment holes; and a shock attachment portion having a plurality of attachment holes. Further, the bracket assembly may include one or more engagement points, configured to support a number of said suspension system components, such as at least one trailing arm, an anti-roll bar, a shock absorber coupler, and a shock absorber.

Movable skid plates for a vehicle are described that are configured to move in response to movement of a first or second link to which the skid plate is coupled. Preferred vehicles comprise a multi-link suspension system having a plurality of links, at least some of which can move independently of one another. The skid plate is preferably disposed below the two bottom links of the suspension system. The skid plate can be fixedly attached to one of the two bottom links. The skid plate can be coupled to the other of the two bottom links such that the skid plate can move with respect to that link.

A suspension structure of a utility vehicle includes: an upper arm including a front shaft support portion supported at front with respect to a vehicle body frame and a rear shaft support portion supported at rear with respect to the vehicle body frame; and a lower arm located below the upper arm and including a front shaft support portion supported at front with respect to the vehicle body frame and a rear shaft support portion supported at rear with respect to the vehicle body frame. In a top view of the utility vehicle, the front shaft support portion of the upper arm is located behind a mechanism side connecting portion, which is coupled to a final speed reduction mechanism, of an axle shaft for coupling the final speed reduction mechanism and a rear wheel.

The present disclosure discloses an all-terrain vehicle including a frame; a trailing arm, an upper tie rod and a lower tie rod. A front end of the trailing arm is connected to the frame. An inner end of the upper tie rod is connected to the frame and an outer end of the upper tie rod is mounted at a rear end of the trailing arm. An inner end of the lower tie rod is connected to the frame and an outer end of the upper tie rod is mounted at the rear end of the trailing arm. The lower tie rod is located below the upper tie rod. An included angle between the upper tie rod and the lower tie rod being a, and a satisfies a relationship: 0°<a<5°.

A bump stop assembly for a UTV with a frame attachment, a shock absorber attachment, two panels, a shock absorber and a bracket. The frame attachment is coupled to the frame of the UTV and the shock absorber attachment is coupled to the shock absorber. The two panels extend between the frame attachment and the shock attachment. The bracket is coupled to the trailing arm of the suspension system of the UTV. The bump plate bracket has a bump plate located to contact the shock absorber when a force applied to the suspension system causes the suspension system to reach a predetermined level of a capacity of the suspension system to absorb. The bump plate transfers a portion of the force applied to the shock absorber. The shock absorber is configured to absorb energy transferred to the bump stop assembly by the force applied to the suspension system.

Described are devices, systems, and methods that enable greater control and customization of variable suspension systems via mechanical modification, among other advantages. In one example, a linkage device is configured to be attached to a suspension arm of a vehicle and to a vehicle frame of the vehicle. The linkage device is configured to mechanically modify one or more physical states detected by a sensor of the vehicle, thereby causing the sensor to output modified signals to a controller, and causing the controller to output modified control signals to a variable shock absorber connected between the vehicle frame and the suspension arm, thereby modifying one or more variable physical properties of the variable shock absorber.

An apparatus and methods are provided for a trailing arm for a rear suspension of an off-road vehicle. The trailing arm comprises an axle support that has a cylindrical shape for supporting roller bearings whereby a wheel hub is rotatable relative to the trailing arm. A joined control arm extends forward of the axle support to an outboard control arm and an inboard control arm. The outboard and inboard control arms are configured to hingedly couple to a chassis of the vehicle. An outboard chassis mount and an inboard chassis mount operate as pivots that place the trailing arm into a hinged relationship with the chassis. The tailing arm is configured to be interchangeable between a driver side and a passenger side of the off-road vehicle. Bulkheads are arranged within an interior chamber of the tailing arm and configured to impart structural integrity to the tailing arm.

An apparatus and methods are provided for a front structural bulkhead for improving the strength of an off-road vehicle chassis. The chassis is a welded-tube variety of chassis that includes a front portion and a rear portion that are joined to an intervening passenger cabin portion. Frontward stays and a bulkhead mount couple the front structural bulkhead to the front portion. Bulkhead mount pillars and a bulkhead mount crossmember couple the front structural bulkhead to the passenger cabin portion. The front structural bulkhead includes a modular chassis for supporting drivetrain components that are operably coupled with front wheels of the vehicle. The front structural bulkhead includes upper and lower mounting points configured to receive front suspension controls arms. The upper and lower mounting points are configured to allow the front wheels to move vertically due to the vehicle traveling over terrain.

A front lower suspension connection for a space frame comprises a U-shaped base and upper suspension control arm support sections on the U-shaped base. The U-shaped base can have a cross-beam section and suspension column support beam sections positioned at opposite ends of the cross-beam section, where each suspension column support beam section may include lower suspension control arm pivot joint supports located at opposite ends of the suspension column support beam sections. Each upper suspension control arm support section can have a first support column and a second support column spaced from the first support column, where the first support column may include a first upper suspension control arm pivot joint support, and the second support column may include a second upper suspension control arm pivot joint support and a front mounting surface. A rear mounting may be provided on a rear surface of the front lower suspension connection.

The present invention relates to all terrain vehicles having at least a pair of laterally spaced apart seating surfaces. More particularly, the present invention relates to trail compliant side-by-side all terrain vehicles.
