The invention relates to a wheelchair provided with a support frame that is suspended on at least a rear wheel and a front wheel by means of a rear and front coupling. At least one coupling comprises means that can shift the support frame with respect to at least one wheel axle, such that a torque can be transmitted to the at least one wheel axle. In particular, the means comprise a lever, one end of which is rotatably connected to the relevant wheel axle and the other end of which is rotatably connected to the support frame. The invention also relates to a coupling mechanism, clearly intended for suspending a wheelchair support frame on a wheel of the wheelchair.
