Truck frame with rear-end collision protection function

Abstract

The invention relates to the technical field of truck frames, in particular to a truck frame with a rear-end collision protection function. The truck frame comprises longitudinal beams and cross beams, the right ends of the longitudinal beams are fixedly connected with a buffer protection device, and the buffer protection device comprises first springs, a first buffer plate, a second spring, limiting blocks, a second buffer plate, a sliding column, a connecting shell, fixing cylinders, third springs, piston heads, piston rods, fourth springs, baffles, plug pins, limiting shafts and fixing plates. According to the truck frame, through the second buffer plate, the sliding column, the connecting shell, the fixing cylinders, the piston rods, the baffles and the plug pins arranged, a truck is preliminarily buffered through the action of the first buffering plate, instant impact force borne by the truck is reduced, secondary buffering protection on the truck is achieved through the action ofthe piston heads and piston cylinders, thus buffering force borne by the truck is reduced again, and meanwhile through mutual clamping of the plug pins and the piston heads, the situation that the piston heads shake on the inner sides of piston sleeves when the truck runs normally can be prevented.

Description

technical field [0001] The invention relates to the technical field of truck frames, in particular to a truck frame with rear-end protection function. Background technique [0002] The frame is also called the girder. The base of the car is generally composed of two longitudinal beams and several cross beams. It is supported on the wheels through the suspension device, front axle, and rear axle. It has sufficient strength and rigidity to bear the load of the car and from the wheels. The incoming impact, frame design and structure are good or bad, the first thing you should clearly understand is the various forces that the frame will bear when the vehicle is running. [0003] Most of the truck frames currently on the market have simple structures and single functions. The general truck frame does not have the function of rear-end buffer protection, which increases the degree of damage when the car collides with the rear, which is not conducive to the use of the driver.

Problems solved by technology

[0003] Most of the truck frames currently on the market have simple structures and single functions. The general truck frame does not have the function of rear-end buffer protection, which increases the degree of damage when the car collides with the rear, which is not conducive to the use of the driver. The frame does not have the function of arranging and limiting the lines, and it is easy to cause confusion of the lines. Therefore, a truck frame with a rear-end collision protection function is proposed to solve the above problems.
