Abstract

The invention discloses a traction device and a traction guide unit thereof. The traction guide unit comprises a frame, a first guide wheel and a second guide wheel, wherein the first guide wheel and the second guide wheel are rotatably arranged in the frame and have a fall in height. Compared with the prior art, the traction device and the traction guide unit thereof have the advantage that the first guide wheel and the second guide wheel have the fall, so that a going cable and a return cable are distributed up and down in a track, thereby reducing the width of the track and reducing the cost of the traction device.

Description

technical field [0001] The invention relates to a traction device and a traction guide unit thereof. Background technique [0002] Road traffic safety has attracted much attention, and vehicle passive safety has become the focus of attention. In the process of vehicle development, a series of safety tests are required to test the overall safety performance of the vehicle. In the full-vehicle crash test, the vehicle hits the barrier along the road surface with the traction device. The traction device includes a traction drive unit, a track set under the road surface, a sliding block sliding along the track, a cable for pulling the sliding block sliding, and a traction pulley system. The vehicle is connected with the sliding block, and the traction drive unit drives the traction cable to drag the test vehicle to complete the vehicle collision test, and the traction cable runs through the entire traction collision system through the traction pulley system. The traction guide...
