Axle Suspension System For Trucks

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.

1 . An axle suspension system for vehicles for enabling smooth drive on heavy snow roads as well as on normal highways, comprising:
 a. at least one axle unit comprising at least two wheels adaptable for snow ride; and   b. a means for moving the at least one axle unit between a bottom position and a top position, such that the at least two wheels make ground contact and the rear wheels of the vehicle are elevated off the ground in the bottom position and the rear wheels make ground contact and the at least two wheels are elevated off the ground in the top position.   
   
   
       2 . The system of  claim 1 , wherein the means for moving the at least one axle unit comprises at least one pneumatic/hydraulic pump and at least one pneumatic/hydraulic cylinder in connection with the at least one axle unit and the at least one pump. 
   
   
       3 . The system of  claim 2 , wherein the at least one axle unit moves up and down between the top and bottom positions when the at least one pump is activated and the pump shuts down automatically when the movable axle unit reaches the topmost and the bottommost positions. 
   
   
       4 . The system of  claim 2  further comprises at least one axle suspension for connecting the at least one axle unit to the vehicle, the at least one pneumatic/hydraulic cylinder being in connection with one of the ends of the at least one axle suspension. 
   
   
       5 . The system of  claim 4 , wherein a piston extending from the at least one cylinder is connected to one of the ends of the at least one axle suspension such that the at least one axle unit moves between the top position and the bottom position as the piston moves up and down when the pump is activated. 
   
   
       6 . The system of  claim 1 , wherein the bottom position of the at least one axle unit facilitates safe driving of the vehicle on heavy snow roads and the top position enables normal drive along highways. 
   
   
       7 . The system of  claim 1 , wherein the at least one axle unit is mounted before the rear wheels of the vehicle. 
   
   
       8 . The system of  claim 7  further comprises a first axle shaft connecting a transmission unit of the vehicle and the at least one axle unit and a second axle shaft for transmitting power from the at least one axle unit to the rear wheels of the vehicle 
   
   
       9 . The system of  claim 1 , wherein the at least two wheels of the movable axle unit are wrapped with a chain. 
   
   
       10 . The system of  claim 9 , wherein the chain is made of titanium/steel.
