Problems solved by technology

Due to the different positions of the center of mass of different types of semi-trailers, it is necessary to replace different types of semi-trailers when carrying out the operational stability test of semi-trailer tractors. The test cost is high, the semi-trailer is prone to rollover, the test safety is poor, and the test cycle is long.

Abstract

The invention relates to the field of vehicles, and discloses a semitrailer for a test. The semitrailer for the test comprises a test load tool and an auxiliary supporting wheel device. The test loadtool comprises a base, a support, an installation frame, a weight box and a supporting column, and the auxiliary supporting wheel device comprises a hanging longitudinal beam, a first truss, a secondtruss, a first supporting wheel and a second supporting wheel. According to the semitrailer for the test, an occupied space is saved, and an influence on a test result due to simulated load shaking ina test process is avoided; simulation load loading time is reduced; test efficiency is improved; and the semitrailer is large in mass center position adjusting range, can meet operation stability test requirements of most semitrailer tractors, can meet test requirements of multiple mass center positions without replacing different types of semitrailers, can assist in supporting the semitrailer under extreme working conditions, and prevents tire burst caused by an overlarge stress of wheels of the semitrailer for the test.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a test semi-trailer. Background technique [0002] Semi-trailer tractors are commercial vehicles equipped with special devices for towing semi-trailers. The front of the vehicle with driving ability is a tractor, and the vehicle without traction driving ability behind is a trailer, and the trailer is towed by the tractor. There are two ways to connect the tractor and the trailer: the first connection is that half of the trailer is placed on the traction saddle at the rear of the tractor, and the tractor also bears part of the weight of the trailer, which is a semi-trailer; The method is that the front end of the trailer is connected to the rear end of the tractor. The tractor only provides the pulling force forward and does not bear the downward weight of the trailer. This is a full trailer. [0003] Semi-trailers include self-unloading semi-trailers, low-bed semi-trailers, barn-type se...
