The invention discloses a heavy-duty vehicle gear-rack type secondary rear protection device which aims to solve the problems that in the prior art, a rear protection device is easily damaged and fails, a rear vehicle easily drives in, the weight is high and cost is high. The secondary rear protection device comprises a protection device frame, a main protection transmission shaft assembly, an auxiliary protection transmission shaft assembly, a main protection sliding way assembly, a main protection rear bumper assembly, an auxiliary protection rear bumper assembly, a sensor controller assembly and a dual-output motor. According to the heavy-duty vehicle gear-rack type intelligent secondary rear protection device, a stepping motor and a mechanical transmission device are adopted to control a main rear bumper and an auxiliary rear bumper of a heavy-duty vehicle, gear drive and gear rack drive are adopted to apply output torque of the dual-output motor to the main protection rear bumper and the auxiliary protection rear bumper, the main protection rear bumper and the auxiliary protection rear bumper are controlled to move linearly, and the ground clearance of the rear protection device can be adjusted according to actual operating conditions. The rear protection device is sturdy, durable, long in service life, simple in structure, convenient to install, low in cost and easy to marketize.
Description
technical field [0001] The present invention relates to a secondary rear guard for vehicles, more precisely, the present invention relates to a heavy-duty rack and pinion secondary rear guard. Background technique [0002] At present, the research on the rear protection device of heavy-duty vehicles at home and abroad is mainly based on the purely mechanical rear protection device, which is rigidly connected with the rear frame of the heavy-duty vehicle, which not only affects the passability of the heavy-duty vehicle, but also affects the The damage to the rear protection device caused by driving cannot guarantee its good protection function. In addition, because the rear protection distance of heavy vehicles is relatively high from the ground, when vehicles such as cars or off-road vehicles collide with heavy vehicles, it is easy to cause vehicles such as cars or off-road vehicles to "drill into" the rear suspension of heavy vehicles, causing great damage. casualties. At...
