The cab mountings support consists of a cylinder (2) enclosing a piston rod (3). The latter is guided in two widely spaced bushes (4,5), and the space between the bushes is divided into two chambers (7,8) by a sealing ring (9) on the piston rod. The sealing ring is provided with a non-return valve (10) which opens in one direction only, and with a throttling orifice. A helical coil spring surrounds the cylinder, with one end abutting against a carrier (23) attached to the cylinder. The other end of the spring is supported in a carrier (19) which rests on rods (20) which abut against a flange (21) connected to the piston rod. |
