Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] see Figure 1 to Figure 2 , a semi-trailer used for the field test of the tractor vehicle, including a compartment 1, a frame, a leaf spring, an axle, a tire assembly, a traction pin, a rope tensioner, a rope hook, a tail light and a side light. The total length of the semi-trailer is 7700mm, the total width is 2500mm, and the total height is 2440mm, that is, the overall size of the semi-trailer is 7700mm*2500mm*2440mm, which can pass all the test roads in the vehicle field test.

[0020] see figure 1 , the two ends of the front end beam of the compartment 1 are respectively provided with supporting legs 2 . Further, a pneumatic device 4 and an electric control switch 3 are arranged above the support leg 2 . The pneumatic device 5 is used to provide power for the expansion and contraction of the support legs 2, so that the s...

Abstract

A semitrailer for a whole motor tractor site test comprises a trailer compartment (1), a trailer frame, a steel plate spring, an axle, a tire assembly, a traction pin, a rope tightener, a rope hook, tail lamps and side lamps. The total length of the semitrailer is 7700 mm, the total width is 2500 mm, and the total height is 2440 mm. Supporting legs (2) are arranged at the two ends of a cross beamat the front end of the trailer compartment (1) correspondingly. The requirement for trafficability of the whole motor tractor test site is met through all test road surfaces in the whole motor tractor site test.

Description

technical field [0001] The invention relates to a trailer, more specifically relates to a trailer used for field testing of a tractor vehicle, and belongs to the technical field of automobile testing. Background technique [0002] At present, the types of semi-trailers mainly include 11-meter barn semi-trailers, 13-meter barn semi-trailers, 13-meter box-type semi-trailers and low-bed semi-trailers. In most semi-trailers, the axle is placed behind the center of gravity of the vehicle and is equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. [0003] The existing trailers cannot meet the requirements of part of the field test in the whole vehicle test process due to the long trailer and other reasons. Usually, the existing semi-trailer has the following disadvantages in the tractor vehicle test: 1. The tractor vehicle field test includes the strengthening factor Larger twisted road driving, Belgian road driving, washboard road dri...
