Work Vehicle
A work vehicle according to the present invention includes left and right axle cases of a rigid axle type, and left and right suspension mechanisms movable in the up-down direction relative to body frames and separately supporting the left and right axle cases, respectively. The work vehicle also includes (i) a first projection projecting downward from the left or right one of the body frames, (ii) a second projection projecting upward from that position on either the left and right axle cases or a frame body integrated with the axle cases which is opposite to the first projection in the left-right direction, and (iii) a lateral rod having a first end connected with the first projection and a second end connected with the second projection.
Rear axle of a vehicle
A rear axle of a two-track vehicle includes a plurality of wheel-control links with at least one spring link for supporting a bearing spring on a vehicle body of the vehicle, which wheel-control links connect a rear wheel of the vehicle to a rear axle carrier. The rear axle carrier includes at least two longitudinal members oriented at least approximately in the longitudinal direction of the vehicle and at least one crossmember oriented at least approximately in the transverse direction of the vehicle. The rear axle carrier is attached to the vehicle body via two bearing points on each side of the vehicle, as viewed with respect to the longitudinal center axis of the vehicle. The spring link and at least one of the wheel-control links are attached to the longitudinal member. The attachment of the spring link to one longitudinal member in each case is arranged, as viewed in the travel direction of the vehicle, upstream of the center of the distance between the bearing points arranged on a common side of the vehicle.

Drive system of an electric vehicle
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.
ASSEMBLY FOR A HYDRAULICALLY SUSPENDED VEHICLE AXLE
An assembly for a hydraulically suspended vehicle axle may have a central housing, and at least two hydraulic suspension components supported on the central housing and fluidly connected to one another by a fluid line extending at least partially through the central housing.
Electric or hybrid electric vehicle having adjustable vertical electric drive motor and method of making and using
An electric or hybrid electric vehicle comprises a vehicle chassis extending along a longitudinal axis and a rotatable vehicle drive axle disposed along a transverse axis and having opposed ends that are configured for attachment to a pair of opposed drive wheels. The electric vehicle also comprises a selectively movable electric propulsion motor comprising a rotatable motor shaft rotatable about a motor axis, the electric propulsion motor configured to be mounted within the vehicle chassis and operatively coupled to the rotatable vehicle drive axle and opposed drive wheels, the motor axis configured to be oriented in a substantially vertical direction, a selectively movable differential disposed on the drive axle and configured to operatively couple motive power of the electric propulsion motor that is transmitted to the rotatable motor shaft to the drive axle, and a motor actuator operatively coupled to the electric propulsion motor and the vehicle chassis.
CRADLE ASSEMBLY FOR AN ELECTRIC AXLE ASSEMBLY
A cradle assembly for housing and supporting a motor and a gearbox of an electric axle assembly. The cradle assembly has generally an “open air” design which provides a space for a motor and/or gearbox to be positioned within a pre-assembled cradle assembly and allows for easy access to the motor and gearbox for maintenance. The cradle assembly includes two end caps, a plurality of tube portions connecting the end caps and a plurality of motor mounts for supporting the motor and gearbox.
VIBRATION-DAMPING DEVICE BODY AND VIBRATION-DAMPING DEVICE
A vibration-damping device body (10) is provided that includes a first mounting member (11) mounted on one of a vibration-generating portion and a vibration-receiving portion via a bracket (2), a second mounting member (12) mounted on the other of the vibration-generating portion and the vibration-receiving portion, and an elastic body (13) connecting the first mounting member (11) and the second mounting member (12). The first mounting member (11) is fitted into a fitting hole (2a) formed in the bracket (2). A first guide portion (30) is formed on an outer circumferential surface of the first mounting member (11). A second guide portion (2f) is formed on an inner circumferential surface of the fitting hole (2a). The first guide portion (30) is fitted into the second guide portion (2f). The first mounting member (11) is formed of a synthetic resin material, and a metal fitting (40) having first engagement surfaces (42a) coming into contact with the second guide portion (2f) is arranged on the first guide portion (30).
AXLE ASSEMBLY FOR LOW FLOOR VEHICLE
An axle assembly for a low floor vehicle is described herein. The axle assembly includes an axle housing and a drive unit for driving a wheel assembly. The axle housing including a first gearbox, a second gearbox and a cradle assembly coupling the first gear box to the second gear box. The axle assembly includes first and second hub assemblies that form a first axis of rotation. The first gearbox includes an electric motor that is coupled to a transmission used to rotate an output shaft. The first gearbox also includes a differential mounted for rotation with the transmission and a first drop box mounted for rotation with the differential. The axle assembly also includes a portal axle mounted for rotation with the first drop box and extends from the first gearbox to the second gearbox wherein the portal axle forms a second axis of rotation that is offset from the first axis of rotation of the hub assemblies. The second gearbox includes a second drop box mounted for rotation with the portal axle and is adapted to drive the second hub assembly.
Motor drive device
A motor drive device includes: a trailing arm that extends in a vehicle front-rear direction and includes a vehicle body-side attachment portion and wheel-side support portion, the vehicle body-side attachment portion formed on a forward portion side of the trailing arm and coupled to a vehicle body via a rubber bush, the wheel-side support portion formed on a rear side of the trailing arm and supporting a rear wheel; and a motor that is supported by the trailing arm and drives the rear wheel.
