Abstract: A truck rack system comprising at least two T-bars, a means for storing the T-bars and a means for connecting the T-bars to the truck at different locations and at different positions to create a rack and to facilitate towing. The means for storing the T-bars comprises a pair of sleeves for each T-bar attached to the bottom of the truck on left and right sides. The elongate portion of the T-bar is tightly received in the pair of sleeves for storing. The means for connecting the T-bar to create the rack comprises holes on front and rear bumpers of the truck for connecting the T-bars vertically.

Abstract: An axle suspension system for vehicles for enabling smooth drive on heavy snow roads as well as on normal highways, comprising at least one axle unit having at least two wheels adaptable for snow ride and a means for moving the at least one axle unit between a bottom position and a top position. The at least two wheels make ground contact and the rear wheels of the vehicle are elevated off the ground in the bottom position. The rear wheels make ground contact and the at least two wheels are elevated off the ground in the top position.

Abstract: A truck bed cover assembly installed over a truck bed comprising a plurality of rigid inverted U-shaped covers, a plurality of tracks located one below the other on sidewalls of the truck bed, two motors and two threaded shafts connected to the motors. The covers include a projecting member extending outwardly from and along the length of its free ends. The covers are of different size and form a telescopic arrangement when their projecting members are received in the tracks. The projecting members on the last cover include a threaded bore for receiving the threaded shafts. When the motors are activated, the rotary motion of the threaded shafts imparts a linear motion to the last cover, which in turn is adapted to pull or push the rest of the covers, thereby covering or uncovering the truck bed.

Abstract: An extension and ramp assembly for use with the truck beds. The assembly comprises a truck bed floor portion and a cargo bed door portion. The truck bed floor portion mainly includes a plurality of shafts and a motor coupled with a bumper, which provides power to extend and retract the bumper along with the truck bed. The cargo bed door portion mainly includes a cargo bed door that is pivotally attached to the bumper such that it can be moved away from the rear end of the truck bed to form an extension parallel to the truck bed. The truck bed when fully extended can be moved down towards the ground to form a sloping surface. The sloping surface formed by the truck bed in conjunction with the pivotally moved down cargo bed door acts as a ramp-like structure.

Abstract: A vehicle for parallel parking includes a front wheel for supporting a portion of a weight of the vehicle, a primary driving wheel to drive the vehicle in a substantially longitudinal direction of the vehicle, a secondary driving wheel to drive the vehicle in substantially a traverse direction of the vehicle.

Abstract: A system for providing a variable traction to a drive wheel of a vehicle includes a front axle for supporting the weight of the vehicle, a rear axle for supporting the weight of the vehicle, a middle axle for providing said variable traction to the drive wheel of the vehicle.

Abstract: A system for automatically adjusting load distribution through axles of a truck and trailer assembly having a pair of rear wheels, the system includes a bridge section having a width, a length, a plurality of bridge legs coupled to it using a coupling apparatus, a central hole bolted to a hook using a hook nut and a hole nearing each corner, a pair of short frames running parallel to the bridge width and being connected to the bridge through said coupling apparatus, a pair of long frames running alongside the short frames, having a plurality of holes equinumber to said plurality of bridge legs, the holes configured to receive the bridge legs, the bridge legs being tightened to the holes using tightening means at an end opposite to the bridge, the long frames being free-floating frames, a pair of airbags seated on top of the long frames, a pair of hydraulic jacks placed inside the long frames, the pair of airbags and hydraulic jacks control the free-floating of the long frames, an air tank or a hydraulic pump
