Abstract

The invention discloses a front-rear-rack hinge-connecting device for a small-sized wheel type loading machine. The front-rear-rack hinge-connecting device comprises a front rack (1) and a rear rack (2), wherein a group of front rack upper in plates (3) is arranged on the front rack; a group of rear rack upper in plates (4) is arranged on the rear rack; pin holes are respectively formed in the front rack upper pin plates and the rear rack upper pin plates, upper pin shafts are respectively assembled in the pin holes. The front-rear-rack hinge-connecting device is characterized in that a position between the two upper pin roller is assembled with a hinge-connecting rod (6) through an upper joint bearing (8), wherein a front rack lower pin roll fixing plate (12) is arranged on the lower part of the front rack, a rear rack lower hinged fixing plate (9) is arranged on the lower part of the rear rack; a lower pin roll (11) is assembled on the front rack lower pin roll fixing plate; a lower joint bearing (10) on the lower pin roll (11) is assembled with the rear rack lower hinged fixing plate (12) in a matched manner. The front-rear-rack hinge-connecting device has the advantage that the gravity center of the rear rack is lowered, the stable performance of the whole vehicle is excellent, the passing-through performance is good, a shaking bracket can be cancelled, the cost is lowered and the reliability is improved.

Description

technical field [0001] The invention belongs to engineering machinery, and more specifically to a small and medium-sized wheel loader in the engineering machinery, specifically a front and rear frame twist connection device of a small wheel loader. Background technique [0002] For the small and medium-sized wheel loaders that are widely used at present, the front and rear frames are modeled on the structure of large wheel loaders, connected by a hinged shaft, hydraulically driven to steer, and the rear frame is installed on the rear drive axle through a swing device. Such a structure will not cause major problems for large wheel loaders due to their large mass and vehicle width, but for small wheel loaders, due to their small mass and narrow body, such a structure will cause The height of the center of gravity of the whole vehicle is high, and the stability of driving and working conditions is poor. When working on some complex terrain, problems such as instability and rol...
