Summary of the invention
The present invention is directed to the little small four-wheel trailer of existing wheel base existing above-mentioned run in the process of moving turn and road that the gradient is bigger on the time, will cause trailer turn dumb, vibration is big, it is unstable to travel and the weak point of roll-over accident easily takes place, provide a kind of run in the process of moving turn and road that the gradient is bigger on the time, turn flexibly, the little small four-wheel trailer of vibration wheel base little, driving stability.
The technical solution used in the present invention is finished in the following way: the small four-wheel trailer that a kind of wheel base is little, it comprises draw bar, vehicle frame, four wheels, rear axle, front axle, wherein: the end of draw bar is fixed on the middle part of front axle, bottom of frame is provided with spring plate, rear axle is contained on the spring plate of bottom of frame, be connected by universal-joint between front axle and the vehicle frame, be respectively equipped with limiting steering mechanism in the left and right sides of front axle.
In above-mentioned small four-wheel trailer, universal-joint is a ball head universal, and it is made up of bulb and locking button, and wherein: bulb is fixed on the middle part of front axle, and the locking button is fixed on the middle part of vehicle frame front side.
In above-mentioned small four-wheel trailer, limiting steering mechanism is made up of limiting steering seat and spacing axostylus axostyle, and wherein: have deep-slotted chip breaker on the limiting steering seat, the head of spacing axostylus axostyle is inserted in the deep-slotted chip breaker, and the afterbody of spacing axostylus axostyle is fixed on bottom of frame.
In above-mentioned small four-wheel trailer, front axle adopts torsion shaft version, is provided with rocking arm at the two ends of front axle, is provided with the spindle nose that is used for adorning front vehicle wheel on rocking arm.
In above-mentioned small four-wheel trailer, afterbody at vehicle frame is provided with Active foot plate, Active foot plate is made up of running-board bracket and pedal, the head of running-board bracket is connected through the hinge on rear axle, both sides at running-board bracket are provided with chute, pedal is inserted in the chute of running-board bracket both sides, is provided with tight locking button in the rear end of vehicle frame, is provided with the dead bolt that matches with tight locking button in the rear end of pedal.
In above-mentioned small four-wheel trailer, be provided with trailer connector and braking mechanism at the head of draw bar, be provided with support wheel at the middle part of draw bar.
Because between front axle on the small four-wheel trailer of the present invention and vehicle frame is to be connected by universal-joint, and front axle adopts torsion shaft version, so the small four-wheel trailer that the present invention and existing wheel base are little is compared, have run in the process of moving turn and road that the gradient is bigger on the time, turn flexibly, vibration is little, the characteristics of driving stability.The present invention is particularly suitable as the trailer of explosive device of delivery and combustible and explosive articles.
