Device for making an articulated connection between two vehicle frames of a construction machine

摘要

#CMT# #/CMT# The device (30) has a connection carrier for connecting an articulated joint and a crab steering joint. A connecting rod is hinged at a rear frame (20) of a vehicle e.g. construction vehicle (1), and at the carrier. A guidance drive is provided for relative pivoting of a front frame (10) of the vehicle and the rear frame around an articulation axis. A crab steering drive adjusts lateral displacement between the frames, and hinged at the carrier and at the frames. The carrier has a common accommodating element for the guidance drive, crab steering drive and rod. #CMT#USE : #/CMT# Device for articulated connection of two frames i.e. front and rear frames, of a vehicle e.g. construction vehicle such as articulated vibrating roller e.g. tandem roller (all claimed) that is utilized for soil compaction. #CMT#ADVANTAGE : #/CMT# The connection carrier has the common accommodating element for the guidance drive, crab steering drive and connecting rod, thus reducing required number of parts of the device, and hence achieving simple structure of the device and reducing manufacturing costs and space requirement of the device in the vehicle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a construction vehicle with a connection device in a normal position. 1 : Construction vehicle 10 : Front frame 11 : Front drum 20 : Rear frame 30 : Device for articulated connection of two frames.
