TWM501391U - Front car of articulated U-frame truck - Google Patents

Abstract

The front car of Articulated U-frame Truck in this creation(or patent), because the chassis is installed on both sides of the damping cylinders, combine with the A-arm suspension (A-Frame) structure, so that the suspension can only swing up and down, and not about the lateral movement. Therefore, the chassis will reduce road vibration effect and fatigue effect, but also improved cab shock.

Description

Front of articulated U-frame framed truck

This creation relates to the head of an articulated U-frame framed truck, and more particularly to the head of an articulated U-frame framed truck with a specially designed chassis suspension mechanism.

Among the articulated heavy-duty vehicles, one style is controlled and driven by the front car, and the U-shaped frame of the rear body is designed. The body hydraulic power is used to achieve the function of dumping and unloading, and the factory often supplies scrap, steel coil or ore. Purpose, this type of vehicle is called a U-framed container truck. The front chassis of the old U-framed container truck mainly supports the power system and the front wheel axle. The wheel system is directly fixed on the chassis, and the vibration of the road surface is directly transmitted from the wheel to the chassis, which causes the chassis structure to be prone to fatigue cracks, which affects safety and high maintenance cost. In addition, a suspension system consisting of a spring and a hydraulic shock absorber is provided around the cab to provide shock absorption. However, this shock absorption effect is not good, and it is not suitable for long-term personnel work.

In view of this, there is a need to propose a solution to solve the above problems.

The purpose of this creation is to provide a front end of an articulated U-frame framed cart.

In order to achieve the above purpose, the front end of the articulated U-frame framed loading vehicle of the present invention comprises: a chassis; an A-shaped arm disposed under the chassis; and a spherical planar bearing disposed on the front end of the A-shaped arm And connected to the underside of the chassis; an axle connected to the rear end of the A-shaped arm; And a cab, located above the chassis.

According to the front of the articulated U-frame framed truck of the present invention, since the shock-absorbing hydraulic cylinder is mounted on both sides of the chassis, and the structure of the hanging A-frame is used, the suspension can only swing up and down. Without lateral displacement. Therefore, the main body of the chassis is less affected by the vibration of the road surface, the fatigue of the chassis is reduced, and the vibration of the cab is also improved.

In order to make the above and other objects, features and advantages of the present invention more comprehensible, the following detailed description will be made in conjunction with the accompanying drawings. In the description of the present invention, the same components are denoted by the same reference numerals and will be described above.

Referring to Figures 1 through 5, the front end of the articulated U-frame truck has a chassis 110 with an A-shaped arm 120 disposed beneath it. A spherical planar bearing 130 is disposed on the front end of the A-shaped arm 120, and the spherical planar bearing 130 is coupled to the underside of the A-shaped arm 120 and the chassis 110. In addition, the axle 140 of the front end is connected to the rear end of the A-shaped arm 120. The front end also includes a transverse pull rod 150 having one end attached to one side of the rear end of the A-shaped arm 120 and the other end coupled to the chassis 110. A damping hydraulic cylinder 160 is mounted on each side of the chassis 110. One end of each of the damping hydraulic cylinders 160 is coupled to the chassis 110, and the other end is coupled to the driver's seat 170 of the front.

According to the front end of the articulated U-frame frame truck of the present invention, when the uneven road surface is passed, the axle 140 is fixed on the A-shaped arm 120, and the spherical flat bearing 130 is disposed on the front end of the A-shaped arm 120. Provides power transmission and multi-directional inclination, thus enabling the A-arm 120 to swing obliquely. In addition, the horizontal tie rod 150 restricts excessive left and right swing of the A-shaped arm 120, so that the free direction mainly moves up and down, and then the shock-absorbing hydraulic cylinder 160 on the left and right sides of the chassis 110 can be squeezed instantaneously under stress. Compression, guiding the hydraulic energy to compress the nitrogen in the shock absorbing cylinder 160, and attracting the force of the road vibration.

According to the front of the articulated U-frame framed truck of the present invention, since the shock-absorbing hydraulic cylinder is mounted on both sides of the chassis, and the structure of the hanging A-frame is used, the suspension can only swing up and down. Without lateral displacement. Therefore, the main body of the chassis is less affected by the vibration of the road surface, the fatigue of the chassis is reduced, and the vibration of the cab is also improved.

Although the present invention has been disclosed in the foregoing examples, it is not intended to limit the present invention, and any one of ordinary skill in the art to which the present invention pertains can be modified and modified without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this creation is subject to the definition of the scope of the patent application attached.
