    摘要: A snowmobile includes a chassis, at least one ski, and a skid frame that includes one or more slide rails extending longitudinally, rear idler wheels, upper idler wheels, and a rear suspension. The rear suspension may further include a flexible, composite member, a rear shock connected between the one or more slide rails and the upper cross member, a rear shock link, a rear cross member connected between the one or more slide rails and a lower shock pivot member pivotally connected to the rear cross member. The rear shock is connected to a rear portion of the lower shock pivot member and the rear shock link is connected via a spherical pivot joint to a forward end of the lower shock pivot member. The flexible, composite member is coupled at a first end to the one or more slide rails and at a second end to the chassis.

    摘要: 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.

    摘要: A driving device for an electric truck which can obtain good ride quality by decreasing the unsprung weight while achieving the adequate fuel efficiency performance by improving the power transmission efficiency and which can improve the mountability of a battery. The driving device includes a driving unit that accommodates therein a motor, a gearbox, and a differential device. The driving unit is supported by a first support part with respect to a ladder frame. Drive shafts coupled to the differential device are accommodated in hollow members. The hollow members are elastically supported by a second support part with respect to the ladder frame.

    摘要: A clamping system for mating an I-Beam frame to an undercarriage is disclosed. The clamping system utilizes clamping brackets to secure the undercarriage to the trailer frame. The undercarriage has adapter sides oriented perpendicular to the undercarriage adapter bottom. The clamping brackets have two portions oriented perpendicular to each other. Holes are located in the clamping brackets to receive bolts or screws. The trailer frame is aligned onto the undercarriage and positioned such that proper tongue weight is applied. The clamping brackets are rigidly installed on the clamping bracket sides. Clamping screws are installed into the clamping brackets and torqued to a value such that a compressive force is applied between the bottom of the I-Beam and the undercarriage adapter bottom. The compressive force applied prevents unwanted relative motion between the I-Beam frame and the undercarriage during use.

    摘要: A fiber-reinforced plastic leaf spring and a method for producing the fiber-reinforced plastic leaf spring are provided, which is suitable in particular for use in a motor vehicle. It has an elongate leaf spring main body which comprises a first eye bushing at a first end and a second eye bushing at a second end. The leaf spring main body and the first and second eye bushings are formed using at least a first layer and a second layer of a composite material. Each of the layers is guided along a centerline of the leaf spring main body to form the leaf spring main body and, to form the first and second eye bushings, is respectively wrapped around a bushing element having a first center axis and around a bushing element having a second center axis.
