A sub-frame arranged to be mounted on a chassis of a car and to have the rear wheels of the car mounted thereon is arranged to receive an electric drivetrain arranged to drive the car. The sub-frame includes a cage including bars arranged to form an upper perimeter and a lower perimeter and a plurality of struts extending between the upper and lower perimeters; a pair of rear wheel suspension mounts, each rear wheel suspension mount being arranged to have one of the rear wheels of the car mounted thereon; and a plurality of brackets located on the cage and arranged to facilitate connection of the sub-frame to the chassis of the car and/or to the electric drivetrain. A frame and vehicle including such a sub-frame and a method of installing such a sub-frame are also disclosed.

A drive mechanism for a skidloader including multiple clutch packs, where each clutch pack selectively connects a drive motor to a corresponding wheel assembly via a unique drive path. More specifically, each drive path produces a unique drive ratio between the drive motor and the corresponding wheel assembly such that the drive mechanism is adjustable between a first drive configuration, in which the motor and wheel assembly are in operable communication via first drive path, a second drive configuration, in which the motor and wheel assembly are in operable communication via a second drive path, and a park configuration, in which the motor and the wheel assembly are in operable communication via both the first drive path and the second drive path.

In a vehicle axle for a motor vehicle, two electric drives are arranged in a frame construction for driving the wheels of an axle. The frame construction is provided with at least one transverse carrier, which is at its ends connected to longitudinal carriers. The two electric drives are arranged approximately axially parallel next to each other with their axes of rotation arranged transversely to the direction of travel. The at least one transverse carrier extends between the two electric drives.

In an aspect, a self-balancing two-wheeled vehicle is provided, having a body, and first and second wheels rotatably coupled to the body. The second wheel has at least one lateral roller rotatable about an axis that is one of oblique and orthogonal to a rotation axis of the second wheel. At least one motor is coupled to the second wheel to control rotation of the second wheel and the at least one lateral roller. At least one sensor is coupled to the body to generate orientation data therefor. A control module is coupled to the at least one motor to control operation thereof at least partially based on the orientation data generated by the at least one sensor.

A rear-wheel drive device 1 includes a first electric motor 102A and a second electric motor 102B, each of which includes an electric motor main body and a rotational-state-quantity detection device. The relative positions between the reference position MS1 of a stator 14A of the first electric motor 102A and the reference position RS1 of a resolver stator 93 of the first electric motor 102A and the relative positions between the reference position MS2 of a stator 14B of the second electric motor 102B and the reference position RS2 of a resolver stator 93 of the second electric motor 102B coincide with each other based on a rotational direction of the first electric motor 102A and the second electric motor 102B which is either the rotational direction during forward movement of a vehicle 3 or the rotational direction during backward movement.

The present teachings relate generally to a small remote vehicle having rotatable flippers and a weight of less than about 10 pounds and that can climb a conventional-sized stairs. The present teachings also relate to a small remote vehicle can be thrown or dropped fifteen feet onto a hard/inelastic surface without incurring structural damage that may impede its mission. The present teachings further relate to a small remote vehicle having a weight of less than about 10 pounds and a power source supporting missions of at least 6 hours.

A leg structure of a quadruped robot includes a body and four separate leg modules. Each leg module includes a thigh motor assembly, a calf motor assembly, a hip joint motor assembly and an associated linkage and fixing base of the hip joint motor assembly. The hip joint motor drives the thigh and calf assembly through a parallelogram mechanism, the thigh motor assembly directly drives the thigh rod assembly, and the calf motor assembly drives the calf assembly through an anti-parallelogram mechanism. The joint motor assemblies are independent of each other and all the motor assemblies are modularized; the thigh and calf motor assemblies have a good ability to prevent external impact, and the joints on the robot body, formed by using the motor assemblies, have a large working space, thus ensuring the movement flexibility of the robot.

A mobile platform for materials transport is provided. The platform includes a pair of suspension devices that in turn include a pair of rocker beams which can be rotated between two positions: a first position where central wheels attached thereto can be used to drive the platform; and a second position where the central wheels are retracted and the platform can be rolled on end wheels without the friction of the central wheels, and an associated drive system, impeding movement of the platform. Furthermore, data from sensors and/or load cells can be used to control movement of the platform; specifically shifts in load distribution and/or sensed forces at the suspension devices can indicate that a load (and/or materials) has shifted and/or is shifting and movement of the platform is adjusted accordingly, for example to prevent the platform and/or the load (and/or materials) from tipping.

A motor gearbox and suspension arrangement is provided for a vehicle. The arrangement includes a drive system for driving a wheel of the vehicle, and the drive system includes an electric motor and a gear train associated with the motor. The arrangement further includes a housing that receives the motor and the gear train, and a suspension control arm having a first end configured to be connected to the vehicle and a second end configured to be connected to the housing.

Systems, methods, and devices for a vehicle windshield are described herein. A vehicle includes a vehicle body comprising a front, a first side, and a second side, wherein the first side and the second side are opposite one another on the vehicle body. The vehicle comprises a cabin located within the body of the vehicle, wherein the cabin comprises an interior that is configured to accommodate at least one person. The vehicle comprises at least one door that provides ingress and egress to the interior of the cabin of the vehicle. The vehicle comprises a windshield that provides a visual line of sight out of the cabin for a user located within the interior of the cabin, and wherein the windshield extends across the front and at least partially on to at least one of the first side or the second side.
