<p>#CMT# #/CMT# The under-carriage (3) is for a trailer (2) and has at least one main axle with at least two wheels and an auxiliary (4) wheel fitted near the front side of the trailer. The auxiliary wheel is rotatable around a vertical control axle and bears a part of the weight of the trailer. The control axle is provided with an adjustable brake, controlled by a dynamo, coupled with the auxiliary wheel, so that the brake force increases with increasing speed of the trailer. #CMT# : #/CMT# At the front side of the trailer is a coupling part (6) for coupling to the towing hook of a vehicle (!) and can hinge freely around a shaft (7), so that the towing hook of the vehicle is not overloaded. The coupling part is provided with a known rising brake (8) for braking the wheels of the rear axle (5). #CMT#USE : #/CMT# As an under-carriage for a trailer. #CMT#ADVANTAGE : #/CMT# With the control axle provided with adjustable friction devices, the friction is generally adjusted so that at an expected cruising speed no wobbling effect occurs. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure portrays schematically in side view a trailer coupled to a vehicle, provided with an under-carriage in accordance with the invention. 1 : vehicle 2 : trailer 3 : under-carriage 4 : auxiliary wheel 6 : coupling part 7 : shaft 8 : rising brake.</p> |
