Technical Field

[0001] This utility model relates to the field of tricycle technology, and more specifically, to a front shock-absorbing suspension steering device for tricycles. Background Technology

[0002] Electric tricycles are three-wheeled transportation vehicles powered by batteries and driven by motors for hauling goods or people. Most existing tricycles use only rigid connections between poles for steering, with steering controlled by handlebars. Their structure is relatively simple, and prolonged use due to vibrations can easily lead to breakage, affecting their lifespan. Therefore, we propose a front shock-absorbing suspension and steering device for tricycles. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a front shock-absorbing suspension steering device for tricycles to solve the technical problem of low service life of current suspension steering.

[0005] Preferably, the connecting block is further provided with a rod sleeve, and the rod sleeve has a connecting hole at its center, which is fixed to an external traction component.

[0006] Preferably, the connecting assembly includes two long rods, with a connecting ring connected to the bottom of the long rods and the connecting ring being fixed to the axle end of the front wheel. A constraint ring is connected to the top of the long rods and the constraint ring constrains the outer portion of the axle of the front wheel.

[0007] Preferably, one end of the shock absorber is hinged to a sleeve, which is located on the outer periphery of the upper half of the central rod.

[0008] Preferably, a fixing plate is installed on the constraint ring, and the other end of the shock absorber is fixedly connected to the fixing plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention further improves the stability of the connection through the cooperation of the central rod and the pressure bearing, as well as the double constraint of the connecting ring and the constraint ring. Furthermore, through the hinged design of the shock absorber and its connection with the connecting components, the shock absorber can flexibly buffer the force of vibration, achieve the effect of shock absorption, reduce damage caused by prolonged bumps, and solve the problem of short service life of the suspension and steering system.

[0018] like Figures 1 to 5As shown, this utility model relates to a front shock-absorbing suspension and steering device for a three-wheeled vehicle, including a pressure bearing 1. The pressure bearing 1 has a hollow structure, with a central rod 3 running through its center. A positioning nut 4 is threaded onto the top of the central rod 3, and a hollow cylinder 5 is connected to the bottom of the central rod 3. A rotating shaft 6 is installed inside the hollow cylinder 5, and a connecting block 7 is installed on one side of the rotating shaft 6. An operating plate 12 is also provided on the connecting block 7, with a connecting hole in its center. The connecting hole is fixed to an external traction component. The traction component can be a connecting rod connected to the front of the vehicle or an electric drive device. A connecting assembly 8 is provided on one side of the connecting block 7, and a shock absorber 9 is provided above the connecting assembly 8. The shock absorber 9 can... Existing hydraulic or spring shock absorbers can be directly used. The connecting component 8 can be selected according to the situation, as long as it can be connected to the front wheel of the vehicle. Here is a preferred solution, the connecting component 8 includes two long rods 801, the bottom of the long rods 801 is connected to a connecting ring 802, the connecting ring 802 is fixed to the axle end of the front wheel, the top of the long rods 801 is connected to a constraint ring 803, the constraint ring 803 constrains the outer part of the axle of the front wheel, one end of the shock absorber 9 is hinged to a rod sleeve 11, the rod sleeve 11 is located on the outer periphery of the upper half of the central rod 3, the other end of the shock absorber 9 is hinged to the area connected to the front wheel, a fixing plate 10 is installed on the constraint ring 803, and the other end of the shock absorber 9 is fixedly connected to the fixing plate 10.

[0019] Working principle: Since the connecting ring 802 is fixed to the axle end of the front wheel and the constraint ring 803 constrains the outer part of the axle of the front wheel, the stability of the connection can be improved. When turning, the traction component is moved by the front of the vehicle, causing the operating plate 12 to rotate, which in turn causes the connecting block 7 and the connecting assembly 8 to rotate, further causing the front wheel to rotate and achieve steering. When passing through bumpy road sections, the shock absorber 9 can play a role in shock absorption, buffering the vibration force and extending the service life.

[0020] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
