Problems solved by technology

[0002] At present, the short-distance movement of the road surface accelerated loading test equipment is mainly driven by a trailer, the operation process is complicated, and the efficiency is low. To solve this problem, the applicant invented a road surface accelerated loading test device on March 19, 2010 The friction all-drive multi-wheel tractor, whose patent number is 201010127375.6, uses friction wheels to drive 6 rubber wheel groups. Since the 6 rubber wheel groups are installed on the same lower bracket, in actual use, there is a steering Difficult problems, resulting in difficulties in traction and transition transportation, and low efficiency

Abstract

The invention provides a fully friction-driven weight-wheel towing vehicle which structurally comprises a towing rod, a lower bracket assembly and an upper frame assembly, wherein the towing rod and the lower bracket assembly are articulated together; the upper frame assembly is movably arranged on the lower bracket assembly, so as to facilitating turning; the lower bracket assembly and the upper frame assembly are of a two-body design; the lower bracket assembly is provided with travelling wheels and a turning driving device; the upper frame assembly is provided with a friction wheel connected with a power device; the friction wheel and the travelling wheels lean against together, and the friction wheel is utilized for providing travelling power to the travelling wheels. According to the fully friction-driven eight-wheel towing vehicle, the eight travelling wheels are respectively arranged on the lower front bracket assembly and the lower rear bracket assembly which are of a split design; a hydraulic cylinder is adopted for realizing turning of the towing vehicle and short-distance movement of towed equipment, so that the towing operation and self-turning maneuverability can be improved; when the towing vehicle is in a free state, the towing rod is pulled, the towing vehicle can be towed to move, an oil cylinder can automatically regulate turning, so that the turning maneuverability is improved, and the turning cost is reduced.

Description

(1) Technical field [0001] The invention relates to a tractor, in particular to a friction full-drive eight-wheel tractor used in conjunction with road surface acceleration loading test equipment. (2) Background technology [0002] At present, the short-distance movement of the road surface accelerated loading test equipment is mainly driven by a trailer, the operation process is complicated, and the efficiency is low. To solve this problem, the applicant invented a road surface accelerated loading test device on March 19, 2010 The friction all-drive multi-wheel tractor, whose patent number is 201010127375.6, uses friction wheels to drive 6 rubber wheel groups. Since the 6 rubber wheel groups are installed on the same lower bracket, in actual use, there is a steering Difficult problems, resulting in difficulties in traction and transition transportation, and low efficiency. (3) Contents of the invention [0003] The technical task of the present invention is to provide a ...
