Trailing arm suspension

A commercial vehicle is described, in particular a field tractor, with a single wheel suspension for unarticulated driven wheels, using transverse swinging arms which are articulated on both sides to a gear box and which guide the wheel supports.Single wheel suspensions are known with transverse swinging arms for guiding the wheel supports. However, these wheel suspensions are either complicated in their structure or are susceptible to damage to the cardan shaft for driving the wheels.A commercial vehicle with a technically simple single wheel suspension for the wheels mounted in wheel supports, guaranteeing safe protection of the cardan shaft driving the wheels from harmful influences, includes a wheel support (8; 33), whicha) together with a spring arm (7; 35) forms a longitudinal swinging arm (16; 21; 37) which is articulated to the gearbox (1) in front of the wheel (4) in the longitudinal direction of the vehicle,b) extends directly to the gearbox (2; 25; 32) andc) fully receives the cardan shaft (12) arranged between the output shaft (5) of the gearbox (2; 25;32) and the assigned wheel shaft (10).The wheel support extending to the gearbox therefore provides the cardan shaft lying in the power flux from the output shaft of the gear to the wheel drive shaft protection against mechanical damage and harmful environmental influences.
