摘要:
A vehicle has a chassis (11) and at least one axle (12, 13) suspended from the chassis for vertical and roll movement relative to the chassis. The axle is mounted on the chassis via a first pivotal mounting means in the form of an upper pair of arms (12a, 13a) which is pivoted on the chassis for vertical pivoting movement relative thereto and which carry an axle support (15, 16) on which the axle (12, 13) is free to pivot in the roll mode. A first damping means (19) acts between the chassis (11) and the first pivotal mounting means (12a, 13a) to control vertical movement of the axle relative to the chassis, and a second damping means acts between the first pivotal mounting means (12a, 13a) and the axle (12, 13) to provide independent control of the roll movement of the axle relative to the chassis. A second lower pair of pivoting arms (12b, 13b) also connect the axle (12, 13) to the chassis to control fore and aft movement of the axle relative to the chassis. When both axles are mounted on the chassis using the above upper (12a, 13a) and lower (12b, 13b) pairs of arms the line of action of the forces (F1-F4) applied to the chassis (11) by the upper arms (12a, 13a) at one end of the chassis may be substantially aligned with the line of action of the forces applied to the chassis by the lower arms (12b, 13b) at the other end of the chassis to reduce and tendency for the chassis to be twisted by these forces.

A vehicle body reinforcement device comprises an elongated shape with its middle portion comprising a hydraulic damper that produces a damping force against longitudinal deformation. Two vehicle body reinforcement devices may be mounted in a longitudinal manner to a vehicle body frame with a lateral space being defined between the two devices. Both ends of each of the vehicle body reinforcement devices can be removably attached from outside of the vehicle to positions that are exposed outside of the passenger compartment and below the vehicle body.

An axle structure for a motor vehicle includes a body of U-shaped configuration with two longitudinal beams and a cross member interconnecting the longitudinal beams at one end thereof. Each longitudinal beam has ends formed as a neck. The longitudinal beams and the cross member are made of two identical metallic shells which extend in congruent relationship and are cemented to one another at least in sections thereof in sandwich-like manner.

An axle/suspension system for a wheeled vehicle, in which the vehicle has a frame, includes an integral arm structure that includes an attachment member for connecting the integral arm structure to the vehicle frame. A flexible transition member is connected to and extends from the attachment member and a body is connected to and extends from the transition member. The flexible transition member may be generally curved or angular and enables pivotal movement of the integral arm structure and cooperates with the body to distribute forces encountered by the axle/suspension system. The body may be a truss structure or a solid body, which may include a member that replaces a conventional axle tube. Optionally, two axle/suspension integral arm structures may be used to capture a conventional axle tube.

A front structure of a motor vehicle increases the energy transfer and dissipation thereof within the front structure upon impact with another object. The front structure includes right and left front side frame members (12, 14) each having a front end (24,26). Right and left front spring hangers (34, 36) extend downward from the front side frame members at a point substantially adjacent to the front ends and each include a bottom end (58) having a mounting flange (56) thereon. A cross member (20) extends transversely within the motor vehicle, having right and left cross member ends (62) attached to the mounting flange (56).

A multiple wheel drive personal transporter includes a lightweight skeletal frame based on a single cylindrical fore-aft beam to which front and rear axle, motor drive and wheel assemblies are connected. Each wheel is driven by a battery powered electrical motor and transmission gear sprocket chain drive. All wheels, or by user control option just front wheels, are powered on in parallel and energized by PWM drive circuitry. Throttle, forward/reverse, steering and other controls are available on a single flight stick. The seat is mounted over the beam near the rear, with front and rear battery trays and the user's weight distributed for optimum stability and traction and the beam is made of telescoped tubular sections incorporating a seat tilt limiting differential that responds to differential rotation of the front and rear wheel assemblies as the transporter traverses uneven ground.

Upon a rear-end collision of a vehicle, an arm section(s) of a cross member of a rear suspension member on the rear side of the vehicle, which is(are) positioned in a low-strength region in a vehicle-body strength distribution, undergoes crush deformation together with a corresponding rear side member(s). Deformation of the part of the rear suspension member other than the arm sections, which is positioned in a high-strength region in the vehicle-body strength distribution, is suppressed, so that a high voltage component mounted in the high-strength region is protected.

摘要:
A motor vehicle having a chassis frame and a vehicle body has switchable connection elements between the chassis frame and the vehicle body. The connection elements are arranged both in front of and behind the connection line of the wheel contact points of the front wheels and/or the connection line of the wheel contact points of the rear wheels. As a result, during cornering, the vehicle body exercises a bending moment upon the chassis frame, which results in a self-steering behavior of the front axle and/or of the rear axle. This self-steering behavior can be influenced in that either the connection elements in front of or the connection elements behind the corresponding axle are triggered such that they exhibit a transverse rigidity that is as high as possible. While the respective other connection elements are triggered such that they exhibit a transverse rigidity that is as low as possible. The triggering takes place by way of a control unit which, for example, uses parameters from the driving operation of the motor vehicle as control variables.
