Abstract

A suspension structure of a trailer caravan comprises a swing arm, a shock absorber, a plate spring lifting lug and a shaft head, wherein the shaft head is fixedly connected with a brake on a tire, the lower part of the shock absorber is connected with the shaft head, and the upper part of the shock absorber is connected with a trailer underframe; the middle part of the horizontal plate spring is fixed with the trailer chassis, and the two ends of the horizontal plate spring are respectively connected with the lower swing arms at the two sides by the plate spring lifting lugs. According to the suspension structure of the trailer, due to the adoption of the double-swing arm and transverse plate spring structure, the tire is accurately positioned, the maximum contact surface is always formed when the tire surface and the ground bump up and down, the tire is ensured to have better ground gripping force, the bearing capacity is increased, the bump of the trailer can be greatly reduced when the trailer runs on a non-paved road surface, the damage of articles in the trailer is prevented, and the comfort is improved.

Description

Suspension structure of trailer

Technical Field

The utility model relates to an automobile suspension, in particular to a suspension structure for a trailer.

Background

Besides the normal road, the motor home can often run or stop on the muddy, uneven and large-fall road surface at the scenic spot. The chassis of the existing trailer motor home is mostly of a single longitudinal arm structure, the comfort is poor when the non-paved road surface runs, the bearing capacity is low, the overload can be hardly caused, and the control performance of the tractor is poor due to the poor stability of the chassis.

Disclosure of Invention

The utility model aims to provide a suspension structure of a trailer caravan, which has the advantages of simple structure, large dynamic stroke of the suspension, strong bearing capacity and good comfort.

The utility model discloses a suspension structure of a trailer caravan, which comprises a swing arm, a shock absorber, a plate spring lifting lug and a shaft head, wherein the shaft head and a brake are fixedly connected on a tire; the middle part of the horizontal plate spring is fixed with the trailer chassis, and the two ends of the horizontal plate spring are respectively connected with the lower swing arms at the two sides by the plate spring lifting lugs.

The working principle of the suspension structure of the trailer caravan is that when a vehicle runs on a bumpy road surface, the tire drives the shaft head to jump up and down, the upper swing arm and the lower swing arm swing under the driving of the shaft head, the transverse plate spring is compressed or stretched to absorb stored energy when the lower swing arm moves, and the shock absorber relieves and absorbs kinetic energy transmitted by the transverse plate spring and the shaft head. And finally, the up-and-down jumping of the wheel is relieved into smaller up-and-down fluctuation under the combined action of the transverse plate spring and the shock absorber.

According to the suspension structure of the trailer, due to the adoption of the double-swing arm and transverse plate spring structure, the tire is accurately positioned, the maximum contact surface is always formed when the tire surface and the ground bump up and down, the tire is ensured to have better ground gripping force, the bearing capacity is increased, the bump of the trailer can be greatly reduced when the trailer runs on a non-paved road surface, the damage of articles in the trailer is prevented, and the comfort is improved.
