Means of transport with balancing construction comprising cylinders, and such a balancing construction

Abstract

The present invention relates to a means of transport, comprising: a frame least two contact members, such as skis or wheels, which am oriented parallel to the direction of forward movement and which are arranged with clearance away from and toward the frame hereon; and a balancing construction between the frame and the contact members for the purpose of preventing slanting of the frame. The balancing construction can herein comprise per wheel at least one compartment filled with fluid and the compartments of at least two of the contact members can be in direct open mutual connection for the fluid.

1 . Means of transport, comprising: a frame; at least two contact members, such as skis or wheels, which are oriented parallel to the direction of forward movement and which are arranged with clearance away from and toward the frame hereon; and a balancing construction between the frame and the contact members for the purpose of preventing slanting of the frame, wherein the balancing construction comprises per wheel at least one compartment filled with fluid and the compartments of at least two of the contact members are in direct open mutual connection for the fluid.  
     
     
         2 . Means of transport as claimed in  claim 1 , wherein the contact members, the compartments of which are in open connection, lie in line.  
     
     
         3 . Means of transport as claimed in  claim 1  or  2 , wherein the compartments are hydraulic or pneumatic cylinders.  
     
     
         4 . Means of transport as claimed in  claim 1 ,  2  or  3 , comprising at least three inline contact members orientated parallel to the direction of forward movement.  
     
     
         5 . Means of transport as claimed in  claim 4 , wherein the contact members are sub-divided into at least two sets, wherein the compartments of the contact members are in open mutual connection in each of the sets.  
     
     
         6 . Means of transport as claimed in  claim 5 , wherein the open connections of at least two of the sets are additionally connected.  
     
     
         7 . Means of transport as claimed in  claim 5 , wherein in the compartments and the open connections of separate sets of contact members different pressures prevail in the fluid under pressure therein.  
     
     
         8 . Means of transport as claimed in any of the foregoing claims, wherein at least one of the contact members is arranged on the frame for tilting on a tilt axis lying transversely of the direction of forward movement, and the balancing construction of the relevant contact member comprises at least two compartments on either side of the tilt axis relative to the direction of forward movement.  
     
     
         9 . Means of transport as claimed in  claim 8 , wherein at least two of the contact members are arranged together on a sub-frame and the sub-frame is tiltable on the tilt axis.  
     
     
         10 . Means of transport as claimed in  claim 8  or  9 , further comprising a brake to be selectively energized, wherein at least one of the tiltable contact members energizes the brake when in tilted position relative to the direction of forward movement.  
     
     
         11 . Means of transport as claimed in  claim 10 , wherein the relevant contact member with which the brake can be energized is the rearmost wheel in the direction of forward movement.  
     
     
         12 . Means of transport as claimed in  claim 10  or  11 , wherein the relevant contact member with which the brake can be energized comprises a tilt axis placed eccentrically relative to the suspension cylinders, wherein energizing of the brake can be enhanced.  
     
     
         13 . Means of transport as claimed in any of the foregoing claims, further comprising at least one connection for feed or discharge of the fluid under pressure in order to selectively increase or decrease the height of the frame.  
     
     
         14 . Means of transport as claimed in any of the foregoing claims, wherein an elastically compressible body of for instance rubber is placed in at least one of the compartments or in the open direct connection.  
     
     
         15 . Means of transport as claimed in any of the foregoing claims, wherein the means of transport is one of the group comprising: roller skates, inline skates, wheelchairs, cars, cross-country vehicles, trucks, caterpillar vehicles, speedboats and so on.  
     
     
         16 . Balancing construction for use in a means of transport as claimed in any of the foregoing claims, comprising per contact member at least two compartments functioning on fluid under pressure, wherein the compartments associated with at least two of the contact members are in direct open connection for the fluid.
