A drive system of an electric vehicle is disclosed. The vehicle has an arrangement optimized for characteristics of a hydrogen electric truck so as to ensure an available space inside vehicle body frames, thereby allowing a battery, high-voltage electric parts, a hydrogen tank, and the like to be arranged inside the vehicle body frames and increasing space utilization in the vehicle. The drive system includes a motor configured to drive the vehicle, a reducer or a transmission connected to an output side of the motor so as to change a rotational speed of the motor, and a rear axle configured to transmit rotating power output from the reducer or the transmission to vehicle wheels. The motor and the reducer or the transmission together with the rear axle are mounted on a suspension.

A wheel suspension of a vehicle intended to extend in a transversal direction of the vehicle in association with first and second wheels arranged on opposite sides of the vehicle, comprising: a subframe unit provided with a set of attachment points for attachment of the subframe unit to a vehicle body structure, wherein the subframe unit comprises a cross member extending along the subframe unit in a transversal direction of the vehicle when the subframe unit is attached to the vehicle; at least a first link member arranged on each side of the subframe unit, wherein each first link member is arranged to connect a corresponding wheel or wheel supporting element with the subframe unit via a pivoted connection; and a spring arrangement arranged to act onto each of the first link members so as to provide for a spring suspension of the first and second wheels.

A dump body pivot pin, suspension node, and rear frame connection comprises a dump body pivot pin boss, a rear suspension connection boss, outer and inner upper rear frame tube connection bosses, outer and inner lower rear frame tube connection bosses, upper and lower beams, a beam connection web, and a support tube connection boss. The dump pivot pin boss has a pivot bore, a pin bore center axis, and inner and outer flat surfaces. The rear suspension connection boss includes a suspension connection center axis and inner and outer flat surfaces. The upper beam connects the outer and inner upper rear frame tube connection bosses to the dump body pivot pin boss. The lower beam connects the outer lower rear frame connection boss to the rear suspension connection boss and the dump body pivot pin boss and the inner lower rear frame tube connection boss to the dump body pivot pin boss.

A front upper frame connection for a space frame can comprise a top surface; a bottom surface opposite the top surface; a right-side surface; a left-side surface opposite the right-side surface; a front surface; a rear surface opposite the front surface; a pair of forward support plates provided on the front surface; a pair of forward flat mounting surfaces; and a pair of rocker attachment interfaces located on the top surface adjacent to the rear surface and respectively the right-side surface and the left-side surface. The front surface and the forward support plates can define a cutout section. Each of the forward support plates is curved and runs outward from a transverse centerline of the top surface and then forward.

A wheel alignment mechanism having a control arm connector, which is adapted for connection to a vehicle suspension control arm positioned between a vehicle chassis and a vehicle wheel, and which has an elongate portion; an inner support frame having a first surface and a second surface on a side of the inner support frame opposing the first surface, the elongate portion of the control arm connector positioned against the first surface at a select one of a first set of plural mounting locations on the first surface, with the first set of plural mounting locations being disposed in a first direction; and an outer support frame adapted to receive a wheel mounting, the connector having a third surface, the second surface of the inner support frame being positioned against the third surface at a select one of a second set of plural mounting locations on the third surface, and with the second set of plural mounting locations being disposed in a second direction approximately perpendicular to the first direction. Means are provided for securing the control arm connector to the inner support frame and the inner support frame to the outer support frame.

In a vehicle subframe 1, a pair of arm support portions S1 and S2 includes an end portion on an outer side of a wall portion 16 in a width direction on a forward side of an upper front cross member 12 in a forward-rearward direction, and wall portions 66 and 86 of a pair of mounting members 60 and 80 on the forward side. Between the pair of arm support portions S1 and S2 in the width direction, the upper front cross member 12 and a lower cross member 32 cooperate with each other to have a closed vertical cross-section that is continuous in the width direction in cross-section taken along a plane parallel to a plane defined by the forward-rearward direction and an upward-downward direction.

A modular, reconfigurable frame that can be combined into multiple standardized segments to create different core vehicle configurations is described herein. The frame includes a plurality of components that affix together universally to make multiple versions of cycle, vehicle, and airframe styles. The reconfigurable frame includes a quick pin and fastener that allows for transportation platforms to be incorporated into the frame in a modular fashion.

A method for producing a mounting arrangement for a link of a motor vehicle suspension that is or can be pivotably mounted on a subframe of the motor vehicle, having the following steps: providing the subframe, which has a first and a second mounting flange for mounting the link; providing at least one intermediate product of a bracket; integrally joining the intermediate product to a mounting flange of the subframe by welding; forming an elongated hole in the intermediate product by punching of the same; and forming at least one stop on the intermediate product for an adjusting eccentric for chassis adjustment by stamping the intermediate product.

A subframe for a rear axle of a motor vehicle includes a transverse structure and a steering device for wheels of the motor vehicle which are fastened to the rear axle. In the installed state of the subframe in the motor vehicle, the transverse structure extends in the transverse direction of the motor vehicle. The transverse structure includes an upper transverse structure element and a lower transverse structure element. The steering device is arranged between the upper transverse structure element and the lower transverse structure element.

A disengagement apparatus for a subframe of a vehicle includes an inclined wall having an inclined surface, two sidewalls, and a top wall. The inclined surface has a structural feature that may include a rib. The disengagement apparatus is configured to couple to the subframe and a subframe stay. The subframe may include an aluminum material, and the disengagement apparatus may include a steel material. Further, a front frame structure for a vehicle includes a vehicle body, and a subframe structure coupled to the vehicle body that includes a subframe, a subframe stay, and a disengagement apparatus. The subframe structure is configured to decouple from the vehicle body in the event of a frontal impact and deflect in a rearward and downward direction relative to the vehicle body.
