Embodiment Construction

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings. The "front and rear" mentioned in this article are defined according to the moving direction or pulling direction of the tractor car under the traction of the motor in the collision test. In other words, the part closer to the traction trolley to the motor is the front end of the vehicle body, and the part closer to the test vehicle is the rear end of the vehicle body.

[0025] see figure 1 and figure 2 , the automobile collision test traction dolly provided by the embodiment of the present invention is used for driving along a horizontal traction direction (such as figure 2 indicated by the middle arrow) towing the test vehicle. The traction trolley includes a body body 1 , a first connection device and a second connection device arranged on the b...

Abstract

The invention discloses a trailer wagon for a car crash test which is used for dragging a test car along a horizontal dragging direction in the car crash test. The trailer wagon comprises a car body, a first connecting device and a second connecting device, and the first connecting device and the second connecting device are arranged on the car body. The first connecting device is connected with a dragging mooring rope. The second connecting device is connected with the test car through a sling. The second connecting device comprises an open hook with an opening, a gear rod and an actuator. The sling can be hung on the open hook through the opening and is separated from the open hook. The gear rod is capable of moving between a first position with a closed opening of the open hook and a second position with an open opening of the open hook. The actuator can drive the gear rod to move from the first position to the second position. The trailer wagon for the car crash test is capable of guaranteeing that the test car can crash a barrier at a regulated speed in a free state.

Description

technical field [0001] The invention relates to a traction trolley, in particular to an automobile collision test traction trolley. Background technique [0002] Automobile crash test is the most basic and effective method to comprehensively evaluate automobile safety performance. The test reproduces the shape of the traffic accident to analyze the motion state and damage of the vehicle and the dummy inside the vehicle before and after the collision, and use this as a basis to improve the vehicle structure design or improve the occupant protection device in the vehicle to improve the anti-collision ability and protect occupant safety. As the automobile crash test is a non-repeatable destructive test for the test vehicle and the test is unique, it is required that the test vehicle must complete the collision accurately and in accordance with the pre-set procedures. In the automobile crash test using the traction trolley, the traction trolley plays the role of connecting and...
