A wheel catcher assembly can inhibit a wheel from moving toward a passenger compartment of a vehicle when an external force is applied to the vehicle. The wheel catcher assembly generally includes an energy absorbing bracket and a plate coupled to the energy absorbing bracket. The energy absorbing bracket includes a plurality of ridges and grooves so as to define a waveform portion. The plate is coupled to the energy absorbing bracket at the ridges such that an external force applied to the wheel catcher assembly is transferable from the plate to the energy absorbing bracket.

Wheel catcher assembly

A load transfer apparatus for a vehicle includes a first deflector member that is securable both to a body mount bracket that extends from a frame rail and to the frame rail so that a first portion of the frame rail is between the body mount bracket and the bumper, and a second portion of the frame rail is between the body mount bracket and the first deflector member. The first deflector member at least partially forms a load path from the bumper to the frame rail under a sufficient offset load applied to the bumper. The load transfer apparatus may also include a second deflector member securable to the bumper to extend from the bumper such that the second deflector member is spaced from and free from contact with the body mount bracket and the first deflector member prior to application of the sufficient offset load to the bumper.

Vehicle load transfer apparatus

A vehicle includes a frame rail that extends along and is longitudinally offset from a longitudinal axis. A load transferring member includes a first axial end that is attached to an outboard surface of the frame rail. The load transferring member extends along a centerline thereof, toward the forward axial end of the frame rail, to a second axial end of the load transferring member. The centerline of the load transferring member extends between the first axial end and the second axial end of the load transferring member to define a concave curved shape relative to the outboard surface of the frame rail. The load transferring member includes a cross sectional shape perpendicular to the centerline of the load transferring member that increases in area, when measured from the second axial end moving toward the first axial end.

Vehicle with lateral load transferring member attached to frame rail

A body structure of a vehicle includes a bulkhead, and a frame rail extending forward from the bulkhead along a longitudinal centerline. A powertrain system is disposed laterally inboard of the frame rail relative to the longitudinal centerline. The frame rail includes a flared section, a splayed section, and a reinforcing member. The flared section curves laterally outboard, away from the longitudinal centerline. The splayed section includes a variable cross sectional area that increases with an increase in distance from the bulkhead. The reinforcing member is operable to increase lateral stiffness in the frame rail, in a direction transverse to the longitudinal centerline. The frame rail is operable to deform into contact with the powertrain system in response to a load applied to a forward end of the body structure and laterally offset from the longitudinal centerline, to generate a lateral force in the body structure.

Automotive frame rail design to manage an offset, frontal applied load

A cradle for mounting an engine in a vehicle has left and right side members, and a rear cross member and front cross member extending between the left and right side members. The cradle has left and right front body mounts. Left and right deflector devices are mounted respectively on the cradle adjacent the left and right body mounts and forwardly of the vehicle wheels. Each of the left and right deflector devices including an impact receiving member that projects outwardly and rearwardly from the cradle to receive an impact load offset outboard from the body mounts. Each impact receiving member has an upper and lower sheet metal shell providing a top wall welded to a top wall of the cradle and a bottom wall welded to the bottom wall of the cradle, and a front impact receiving wall extending vertically between the top wall and the bottom wall.

Engine cradle with deflector device

An engine cradle mounting an engine in a vehicle has left and right side members spaced laterally apart on opposite sides of the engine, a rear cross member having right and left ends attached respectively to the left and right side members, and a front cross member having left and right ends attached respectively to the left and right side members. Body mounts are provided on the left and right ends of the front cross member for bolting the cradle to the vehicle body. Left and right deflector devices are mounted on the cradle, and each includes an impact receiving member that projects outwardly from the cradle to receive an impact load, and a brace member that extends between the cradle and the impact receiving member to brace the impact receiving member and provide a load path transferring the impact load into the cradle.

An impact receiving structure in a motor vehicle includes a vehicle frame having left and right frame rails extending longitudinally and cross frame rails extending transversely between the left and right frame rails. A vehicle body is mounted on the vehicle frame and has a transverse bulkhead and left and right A-pillars connected to the bulkhead. Left and right upper rails extend longitudinally above the front wheels and outboard of the left and right frame rails and are connected respectively to the left and right frame rails by left and right braces. Left and right deflector devices are mounted on the left and right frame rails forwardly of the front wheels and extend outwardly from the left and right frame rails to receive an impact force and transmit the impact force into the frame that would otherwise transmit through the left and right upper rail structures.

Impact deflector for vehicle frame

In accordance with exemplary embodiments, a multi-cell motor compartment rail system is provided for a vehicle. The system comprises an inner rail member and an outer rail member. Partition members couple to the inner rail member and outer rail member and are configured to form multiple cells within the engine compartment rail system when the inner rail member and outer rail member are coupled together. In accordance with exemplary embodiments, a method for forming a multi-cell motor compartment rail is also provided. The method comprises coupling a first partition member to an inner rail member of an engine compartment rail system and coupling a second partition member to an outer rail member of an engine compartment rail system. Next, the inner rail member and the outer rail member are coupled together to form the multi-cell motor compartment rail.

Multi-cell motor compartment rail

A system for absorbing energy in a vehicle includes a pair of laterally spaced upper and lower side rails which extend along a longitudinal axis. The lower side rails are disposed below the upper side rails. An upper member extends transverse to the longitudinal axis and interconnects the upper side rails. A lower member extends transverse to the longitudinal axis and interconnects the lower side rails. The upper and lower members are each disposed to transmit energy from the upper and lower members through the respective upper and lower side rails. The upper and lower members are configured to simultaneously deform upon impact of the vehicle with an object and transfer a force generated from impacting the object to the upper and lower side rails, respectively.

Energy absorbing system for a vehicle

A rail assembly for a vehicle includes a rail member extending longitudinally. The rail assembly also includes an insert disposed within and extending longitudinally along at least a portion of the rail member and having at least one curved section to provide load carrying capacity in the rail member.

Rail assembly for vehicles

A structural assembly for a vehicle includes a structural member extending longitudinally. The structural assembly also includes an insert disposed within and extending longitudinally along at least a portion of the structural member and having at least one corrugation to act as a crush initiator during an axial impact on the structural assembly.
