Description

A curved truck frame

technical field

The utility model belongs to the technical field of wheeled vehicle parts, in particular to a high-strength load-bearing electric vehicle frame.

Background technique

As a transportation truck, wheeled vehicles have the characteristics of convenient use and flexibility, and have been recognized by the majority of the people. They are widely used and develop rapidly. The frame design of existing wheeled trucks generally considers factors such as safety and load. Basically, it can meet the requirements, but the gravity of the cargo is not fully utilized, resulting in large power loss and slow speed during transportation.

Contents of the invention

The purpose of the utility model is to improve the deficiencies of the prior art and provide an arc-shaped truck frame that utilizes goods on the frame to provide forward power, energy-saving power, simple structure, and strong load-bearing capacity.

The purpose of this utility model is achieved in that a curved truck frame is composed of an upper beam, which is characterized in that the lower beam is arc-shaped, and the two ends of the lower beam are fixedly connected with the two ends of the upper beam respectively. The front wheel shaft for installing the front wheels is arranged on the front part of the lower beam, the rear wheel shaft for installing the rear wheels is arranged at the rear of the lower beam, and the steering wheel shaft for installing the steering wheel is arranged on the upper beam or lower beam close to the rear of the front wheel shaft.

In order to further realize the purpose of the utility model, the upper beam and the lower beam can be two and installed in parallel, and the two upper beams and the two lower beams are respectively connected and fixed by cross beams.

In order to further realize the purpose of the utility model, a rear vertical beam can be provided between the rear end of the upper beam and the lower beam, and the tail end of the upper beam and the tail end of the lower beam are connected and fixed by the rear vertical beam for installation. The rear axle of wheel is arranged on the rear portion of lower beam and is close to rear vertical beam place.

Compared with the existing head technology, the utility model has the following remarkable features and positive effects: the lower beam of the utility model is arc-shaped, and the two ends of the lower beam are fixedly connected with the two ends of the upper beam respectively, so that the force of the whole vehicle frame Evenly distributed, able to bear heavier weight; the front wheel axle for installing the front wheels is set at the front of the lower beam, the rear wheel axle for installing the rear wheels is set at the rear of the lower beam, and the steering wheel axle for installing the steering wheel is set close to the On the upper beam or lower beam behind the front axle, the center of gravity of the entire frame is moved backwards, so that the center of gravity is located at the rear of the front axle, so that the self-weight of the frame and the load on the frame can give the wheels a forward decomposition force, so that The entire frame receives a forward thrust, the greater the load, the greater the thrust, so by using its own weight and the weight of the load to drive, it saves power, increases the cruising range, and reduces the cost of use; the upper and lower beams They are two and installed in parallel through the connection and fixation of the crossbeam, which improves the firmness, increases the cargo capacity, and ensures safety; there is a rear vertical beam between the rear ends of the upper beam and the lower beam, and the tail end of the upper beam is connected with the rear end of the lower beam. The tail end of the lower beam is connected and fixed by the rear vertical beam, and the rear axle for installing the rear wheel is arranged at the rear of the lower beam close to the rear vertical beam, which improves stability and safety.
