Abstract
Description
Technical Field
[0001] The utility model relates to the field of lightweight obstacle removal vehicles, in particular to a lightweight obstacle removal vehicle. Background Art
[0002] The lightweighting of vehicles is of great significance for energy conservation and emission reduction, and is the direction of development of automobiles and even special-purpose vehicles. Tow trucks are indispensable emergency operation vehicles on the road. At present, a considerable number of light-duty tow trucks have not been lightweight, and are basically in an overweight working state, unable to meet the requirements of relevant standards. The lightweighting of the upper body has always been the focus of research and development of tow trucks in recent years. Through structural optimization and the use of lightweight materials, some progress has been made, but the weight reduction is limited. If the upper body load-bearing device and the chassis are made lighter through reasonable optimization of the whole vehicle structure, the lightweight tow truck can have a greater load-bearing capacity and better driving safety. Summary of the invention
[0003] In order to solve the problem that the road tow truck is too heavy, the utility model provides a tow truck with a lightweight chassis and an upper load-bearing device. The specific technical solution is as follows:
[0004] A novel lightweight tow truck comprises a chassis frame longitudinal beam, a frame rear cross beam and a subframe, wherein the subframe is mounted on the chassis frame longitudinal beam in a full-contact manner via a rubber pad, a flip hinge pin is provided at the rear end of the subframe, the flip hinge pin is connected to a hinge support welded to the frame rear cross beam, and nylon sliders are installed on the upper and outer sides of the lower subframe.
[0005] The tilting hinge point of the auxiliary frame is located below the upper plane of the chassis frame longitudinal beam.
[0006] The chassis frame longitudinal beam is a U-shaped single-layer structure made of high-strength steel.
[0007] The beneficial effects of the utility model are:
[0008] 1) The subframe of this design is installed on the chassis frame longitudinal beam in a full contact manner through rubber pads, which improves the uniformity of load bearing. There is a flip hinge pin at the rear end of the subframe, so that the subframe can flip backward and upward at a certain angle around the pin under the lifting action of the cylinder. The hinge support is welded to the rear crossbeam of the frame, and the center of the flip hinge point of the subframe is below the upper plane of the chassis frame longitudinal beam, which reduces the weight and center of mass height of the vehicle.
[0009] 2) This design not only has a nylon slider installed on the upper side of the sub-frame between the sub-frame and the slide rail of the load-bearing plate, but also has a nylon slider installed on the outer side of the sub-frame to improve the stability of the load-bearing plate during operation.
[0010] 3) In this design, the chassis frame longitudinal beam is made of high-strength steel into a U-shaped single-layer structure, and the chassis frame longitudinal beam is lightweight. In order to make the tow truck lightweight, the chassis frame longitudinal beam used in the tow truck is made of high-strength steel into a U-shaped single-layer structure, and the curb weight is reduced by more than 200 kg.
