A shock strut for a vehicle includes a housing with a through channel and a motor mount, and a motor fixed to the housing. The cylinder of a shock strut is configured to define a lead screw on its outer surface. The cylinder extends through the housing. The piston of the shock strut is attached to a ground engaging assembly. A gear nut rotatably mounted in the housing threadably engages the threaded cylinder, and is configured to be driven by the motor. The housing is attached to the vehicle, and the gear nut is controllably rotated to extend and retract the shock strut. A sensor provided on the assembly monitors the position of the shock strut. A torsion link assembly reacts rotational forces on the cylinder.

An electric vehicle for routing inspection of power transmission lines, includes a body; a running mechanism mounted to the body, comprising a front wheel and a rear wheel connected by a cross beam and rolling on the cable; an obstacle sensor and a cam rotatably mounted to the cross beam, the cam rotating to roll onto the cable after an obstacle is detected on the cable such that the front wheel is raised to a position above the cable, and the cam continuing rolling on the cable after the front wheel passes the obstacle such that the front portion of the cross beam falls back downwards and the front wheel then falls back onto the cable, a hanging seat rotatably hanging to the body and a control device at least partially disposed in the hanging seat and comprising a braking device.

A steering bogie provided with a pair of tires (13) positioned on both sides in the vehicle-widthwise direction, a primary suspension mechanism (51) for supporting the pair of tires (13) independent from a subframe (11), and a steering guide device (14) which is guided along guide rails (6) extending along a track (5), wherein the steering guide device (14) is equipped with: a guide frame (31); guide wheels (33) which roll as a result of contact with the guide rails (6), and are rotatably supported by the guide frame (31); and a guide frame support mechanism (32) for supporting the guide frame (31) by hanging from the primary suspension mechanism (51).

A wheel and tire assembly for material handling machines for selective operation on or off rails include a monolithic, tubular wheel body divided into an inner tire mounting section and an outer rail engaging section. The tire mounting section is bounded by an inner rim projecting around an inner end of the wheel body and an outer rim projecting radially outward around the wheel body medially between the inner and outer ends thereof. A tire is securable around the wheel between the inner and outer rims. A rail engaging flange projects radially outward from the wheel body in outwardly spaced relation from the outer rim in a spacing adapted for reception of a rail, such as a rail formed on an upper end of a rail car sidewall therebetween.

A rail wheel set for a car which can be moved on a rail of a rail system has a bearing housing with a radial suspension for connecting the rail wheel set to the car, and two running wheels which are rotatably mounted on the bearing housing. Each wheel has a respective rail rolling surface, the shape of which is adapted to the contour of a running surface of the rail, and a respective ground rolling surface. The wheels can roll independently of each other on the running surface of the rail or on the ground. The rail wheel set is secured to a chassis of a car for transporting objects on a rail system.
