Extendable bumper for external vehicle transportation and storage

Abstract: An extendable vehicle bumper for external transportation and storage of objects. A horizontal platform is mounted to the underside of a vehicle frame and is attached at one end to the vehicle bumper. The platform is extendable on a horizontal plane between an open position and a closed position. In the closed position, the platform is supported in a horizontal plane within the vehicle framework on the underside of the rear end of the vehicle. The vehicle bumper serves to access the platform by providing a handle for extending the platform outwardly from the vehicle frame. When the platform is in the open position, the platform extends beyond the vehicle profile and is generally in rigid relation with the vehicle. The horizontal platform is extendable between the open and closed position by support arms fixed to the platform opposite the vehicle bumper.

Step structure for vehicles

Abstract: A step includes a support member extending from a vehicle frame. A first wire rod frame extends from the distal end of the support member to the vehicle frame. A second wire rod frame suspends the first frame from the vehicle frame. Furthermore, a foot board is disposed over the first frame and the support member. The step structure is of high flexibility. The step is capable of flexibly handling loads applied from the ground, and is prevented from being plastically deformed by loads applied from the ground. The first and second frames are made of wire rods. Accordingly, the step structure is made lightweight. As a consequence, the vehicle is made lightweight.

Vehicle frame assembly and method for same

Abstract: A method for assembling vehicular structural frames employing elongated members and connectors interconnecting the elongated members increases flexibility in assembling chassis frames and body frames. The method includes assembling a first vehicle structural frame according to a first design, and assembling a second vehicle structural frame according to a second design. The second design is derived from the first design by replacing elongated members of the first design with differently-dimensioned elongated members, or by changing the quantity of elongated members, to result in a second structural frame configuration different from the first structural frame configuration.

Dynamic effect of the non-rigid modified bicycle model

Abstract: In this paper a method to add elastic effects to the classic ‘bicycle model’ for the simulation of the dynamic behaviour of vehicles is presented. The obtained results show that, in the simulations, dynamic effects such as lateral acceleration are more severe when non-rigid models of the vehicle frame are used. This work demonstrates that the modified bicycle model is a useful instrument to predict the response of a vehicle. At present, much effort is dedicated to simulation with rigid body dynamic programs. The proposed method offers an easy way to evaluate the dynamic effects in models with flexible frames. The elasticity of the frame has an important impact on the directional response (yaw gain and lateral velocity) of the vehicles. This method is useful for analysis from the behaviour of vehicles with modifications made after their manufacture. In the design phase the manufacturer has the suitable tools and the experience to avoid designing frames of low rigidity. Nevertheless, in the second-h...

A fluid pressure accumulator for vehicle suspension

Abstract: An accumulator is provided for a vehicle air system including a vehicle frame. A wheel end is spaced from the frame for supporting the vehicle frame on a roadway. A suspension assembly includes a suspension structure. The suspension structure may be a portion of an axle, a stabilizer bar, a control arm, or other suspension components. The suspension structure is interposed between the frame and the wheel end and is movable relative to the vehicle frame in response to the wheel end receiving inputs from the roadway. A fluid chamber forms the accumulator and is defined by a portion of the suspension structure for storing pressurized air. Preferably a valve is disposed within the fluid chamber to protect the valve from the environment. For light vehicle applications where a conventional air pump may be cost prohibitive, a mechanical pump may be connected between the vehicle frame and the suspension assembly. The mechanical pump provides pressurized air to the fluid chamber in response to relative movement between the suspension assembly and the vehicle frame as the vehicle travels along the roadway.
