Description

Vehicle tractor structure improvement

The present invention relates to a structural improvement of a vehicle tractor, and more particularly to a situation in which the first vehicle collides with the second vehicle to avoid excessive turning, and further provides a tractor for convenient use of the coupling vehicle or the truck.

According to the prior art, the container-coupled vehicle is connected by a tripod in the middle of the towing vehicle and the trailer. The front end of the tripod has a hook hole for hooking the hook connector connected to the rear end of a towing vehicle. The rear end of the hook hole is provided with a traction rod at a symmetrical angle of the left and right sides, and the ends of the two traction rods are symmetrically folded and slanted respectively to the two pivoting lugs of the trailer front end of the trailer, and the fixed axis is coupled with the string connection. Because the trailer has a long body, the driving and reversing operation needs to be led by the front towing vehicle. Therefore, if the driving turning operation is slightly inadvertent, the traction rods on the left and right sides may be damaged due to the excessive turning angle. The lead rod is easily bumped and affects the smoothness of the trailing trailer being towed, and the loading of the trailer and the braking of the trailer are applied to the tripod horizontally. The braking force is caused by the inertia kinetic energy. The terminal is subjected to strong lateral tension. If it encounters the influence of metal fatigue, it is easy to cause stress damage at the end of the traction rod end, which is harmful to driving safety.

Therefore, relevant industry players have made research and improvement on this deficiency, such as the Republic of China 103 years. The new patent No. M470771, "Construction Vehicle-specific Towing Frame Structure", published on January 21, discloses a construction-specific towing frame structure (as shown in Figure 5), comprising: a middle tie rod 7 having a predetermined axis The length S includes an axis 71 and a front end shaft 711 and a rear end shaft 712. The front end shaft 711 is fixed with a hook hole holder 713 for hooking and hooking the hook end of a towing vehicle. The rear end shaft 712 is fixed. And a crossbar 714 is fixed, and an inverted T-shaped structure is constructed, and is divided into a left end portion 7141 and a right end portion 7142 which are bilaterally symmetric with respect to the cross bar 714; a pair of left and right pull rods 72, 73 whose front end 721 is equiangular The symmetry intersection is fixed on the axis 71 of the middle tie rod 7 to form a intersection end, and the intersection end is connected with the three points of the ends of the left and right pull rods 72, 73 to form a high-distance isosceles triangle left and right. The left end portion 7141 and the right end portion 7142 of the left and right sides of the tie rods 72 and 73 are respectively fixedly integrated with the left and right sides of the tie rods 72 and 73, and the ends of the left and right pull rods 72 and 73 are respectively fixed with a trailer for the front end of the trailer. A shaft pivot seat 74 is provided.
