Split hull

Abstract

The following invention relates to split hulls, particularly to V shaped split hulls with a biased resilient member to mitigate against shock or blast. There is provided an armoured land vehicle comprising; a lower armoured v shaped hull; an upper hull which is located above and slidably engaged in a vertical plane with said hull, wherein there is at least one biased resilient member located between said upper hull and lower hull, to reduce the travel between said upper and lower hulls in the event of a shock event.

1 . An armoured land vehicle comprising:
 a lower armoured V-shaped hull; and   an upper hull which is located above and slidably engaged in a vertical plane with said lower armoured V-shaped hull;   wherein there is at least one biased resilient member located between said upper hull and lower armoured V-shaped hull, to reduce the travel between said upper hull and lower armoured V-shaped hull in the event of a shock event.   
     
     
         2 . The vehicle according to  claim 1 , wherein the at least one biased resilient member is at least one elongate rod, spring, variable coiled spring, leaf spring, plurality of thin elongate plates, rubber bushing, or torsion bar. 
     
     
         3 . The vehicle according to  claim 1 , wherein the at least one biased resilient member comprises a fluid damper. 
     
     
         4 . The vehicle according to  claim 1 , wherein the vehicle further comprises a power train, drive motors, and electronic systems which are located in the upper hull. 
     
     
         5 . The vehicle according to  claim 2  wherein the at least one biased resilient member comprises a damper with an external mounted spring. 
     
     
         6 . The vehicle according to  claim 1 , wherein each said at least one biased resilient member has a spring constant/mass which is greater than 100 N/m/Kg. 
     
     
         7 . The vehicle according to  claim 6 , wherein the spring constant/mass is in the range of from 5000 to 10000 N/m/Kg. 
     
     
         8 . The vehicle according to  claim 1 , wherein each said at least one biased resilient member has a spring constant of at least 400 N/m. 
     
     
         9 . The vehicle according to  claim 1 , wherein there are 1 to 10 biased resilient members. 
     
     
         10 . The vehicle according to  claim 1 , wherein the total spring constant/mass for all biased resilient members located between the upper and lower hulls is greater than 500 N/m/Kg. 
     
     
         11 . The vehicle according to  claim 1 , further comprising one or more drive motors, wherein the one or more drive motors consist only of electrical motors. 
     
     
         12 . The vehicle according to  claim 1 , wherein the upper hull comprises at least one wall mounted seat system. 
     
     
         13 . The vehicle according to  claim 1 , wherein the vehicle is a remote controlled vehicle. 
     
     
         14 . The vehicle according to  claim 1 , wherein there is at least one stop, to prevent over displacement of the upper hull and lower armoured V-shaped hull. 
     
     
         15 . The land vehicle according to  claim 1 , wherein the vehicle has a mass of less than 100 Kg. 
     
     
         16 . An armoured land vehicle comprising:
 a lower armoured V-shaped hull;   an upper hull which is located above and slidably engaged in a vertical plane with said lower armoured V-shaped hull; and   a biased resilient member located between said upper hull and lower armoured V-shaped hull, to reduce the travel between said upper hull and lower armoured V-shaped hull in the event of a shock event, wherein the biased resilient member includes at least one elongate rod, spring, variable coiled spring, leaf spring, plurality of thin elongate plates, rubber bushing, or torsion bar.   
     
     
         17 . The vehicle according to  claim 16 , wherein the biased resilient member further comprises a fluid damper or a damper with an external mounted spring. 
     
     
         18 . The vehicle according to  claim 16 , wherein the vehicle further comprises a power train and one or more electrical drive motors, which are located in the upper hull. 
     
     
         19 . The vehicle according to  claim 16 , wherein the total spring constant/mass for all biased resilient members located between the upper and lower hulls is greater than 500 N/m/Kg. 
     
     
         20 . The vehicle according to  claim 16 , wherein the vehicle is a remote controlled vehicle.
