Eddy current slow-speed vehicle with anti-pushing function

Abstract

The invention relates to an eddy current slow-speed vehicle with an anti-pushing function. According to the vehicle, a linking pile is arranged in the center of the rear part of the tractor, a linkingbeam is arranged at the front part of the trailer, the center of the linking beam is hinged to the linking pile, an eddy current retarder is arranged on a transmission shaft of the tractor, and a signaling plate is arranged on the axis of the linking beam; a pair of dangerous angle travel switches are arranged on the swing track of the signaling plate, the two dangerous angle travel switches arearranged on the tractor and are symmetrically distributed by taking the axis of the tractor as a center, so that when the vehicle speed is higher than the safety speed and the axis of the linking beamdeviates from the axis of the tractor and reaches the dangerous turning angle beta, the dangerous angle travel switches are triggered by the signaling plate to enable the eddy current retarder to befailed; and a pair of warning angle travel switches are arranged on the swing track of the signaling board, so that when the vehicle speed is higher than the safety speed and turning reaches the warning turning angle alpha, the warning angle travel switches are triggered to enable the eddy current retarder to operate at a low gear. The vehicle can play a role of the retarder and can ensure safetyduring turning.

Description

Technical field [0001] The invention relates to a trailer equipped with a retarder, in particular to an eddy current slow-speed trailer with the function of an anti-push head, and belongs to the technical field of automobile slow-speed braking. Background technique [0002] With the development of expressways, and people's requirements for driving comfort and safety, higher and higher requirements are put forward for automobile retarders. Under the conditions of frequent braking and deceleration of heavy-duty vehicles and long-distance downhill braking, the retarder can be activated to achieve smooth deceleration and avoid the wear and heat caused by using the brake. Retarders can improve the safety and reliability of car driving, and can also reduce the wear of car brake shoes and wheel hubs and reduce maintenance costs, thus being welcomed by car manufacturers and car users. [0003] Liquid-cooled eddy current retarders have high power density, low continuous braking heat decay,...

AI Technical Summary

Problems solved by technology

When the speed of the vehicle is high, the retarder braking may cause the braking deceleration value of the trailer to be too high because the braking force of the trailer is too large, and the braking device of the trailer does not work. At an angle, the strong inertia of the trailer is transmitted to the trailer through the connecting pin, and the phenomenon of pushing the head occurs, which will make the trailer deviate from the original driving route, and even cause the trailer to overturn

Due to such potential safety hazards, the application of retarders on trailers is limited
