Technical Field

[0001] The utility model relates to the field of suspension, in particular to a hidden torsion bar type chassis front suspension. Background Art

[0002] The suspensions on the market include McPherson suspension, double wishbone suspension, multi-link suspension, etc., which are mostly suitable for road cars and front axle suspensions of off-road vehicles. Torsion bar suspension uses the torsional elasticity of metal rods to absorb and slow down the impact from the ground.

[0003] Since the components of traditional suspension systems are usually exposed to the outside, they are easily impacted and eroded by debris such as stones and dirt. This not only causes wear on the surface of the components, but may also damage the internal structure, reducing the performance and life of the suspension system. Therefore, those skilled in the art have provided a hidden torsion bar chassis front suspension to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the present utility model is to solve the shortcomings existing in the prior art, and a hidden torsion bar chassis front suspension is proposed, in which a spring steel plate is arranged inside a round tube, which is not easily touched and will not be damaged by stones, dirt and other debris to achieve shock absorption. The suspension system can be more durable and the suspension reliability is better. By arranging a spring steel plate in the slot of the cantilever, when the wheel hub is impacted by the road surface, the deformation of the torsion arm will drive the spring steel plate to undergo elastic deformation, and the elastic restoring force of the spring steel plate itself is used to resist the deformation of the torsion arm, thereby achieving the functions of buffering and shock absorption. The round tube made of stainless steel is used as the main supporting structure of the suspension system. Stainless steel has high strength and hardness, and can better withstand the weight of the vehicle and various forces during driving.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a hidden torsion bar chassis front suspension, comprising two circular tubes, the two circular tubes being arranged vertically, cantilevers being provided at the centers of both side walls of the two circular tubes, bearings being provided at the upper and lower centers of the inner centers of the two cantilevers, slots being provided at the upper and lower centers of one side wall of the two cantilevers, spring steel plates being provided at the centers of the two circular tubes, and torsion arms being provided at the upper and lower centers of one side wall of the two cantilevers;

[0006] Through the above technical solution, the spring steel plate is arranged inside the round tube, which is not easily bumped and will not be damaged by stones, dirt and other debris to achieve shock absorption. The suspension system can be more durable and the suspension reliability is better. By arranging the spring steel plate in the slot of the cantilever, when the wheel hub is impacted by the road surface, the deformation of the torsion arm will drive the spring steel plate to undergo elastic deformation. The elastic restoring force of the spring steel plate itself is used to resist the deformation of the torsion arm, thereby achieving the functions of buffering and shock absorption. The stainless steel round tube is used as the main supporting structure of the suspension system. Stainless steel has high strength and hardness, and can better withstand the weight of the vehicle and various forces during driving.

[0007] Furthermore, the two spring steel plates are respectively adapted to fit into the four slots;

[0008] Through the above technical solution, when the wheel hub is impacted by the road surface, the torsion arm is deformed, and the spring steel plate in the slot will also undergo elastic deformation. The spring steel plate resists the deformation of the torsion arm through its own elastic restoring force, thereby playing a role in buffering and shock absorption.

[0009] Furthermore, a connection hole is provided at one side of the center of the upper end surface of each of the four torsion arms;

[0010] The above technical solution is used to connect other components, such as a steering mechanism or a braking system.

[0011] Furthermore, a hub is provided on one side of each of the four torsion arms;

[0012] Through the above technical solution, when the vehicle is driving on the road, the wheel hub is subjected to the force of the road surface, and these forces are transmitted to the torsion arm through the connecting device. The torsion arm undergoes a certain degree of twisting and deformation under the action of the force, and at the same time transmits the force to the spring steel plate.

[0013] Furthermore, the two round tubes are made of stainless steel;

[0014] Through the above technical solution, the round tube, as the main supporting structure of the suspension system, needs to have sufficient strength and rigidity to bear the weight of the vehicle and various forces during driving. Stainless steel has high strength and hardness and can meet the mechanical performance requirements of the round tube.

[0015] The utility model has the following beneficial effects:

[0016] 1. In the present invention, the front suspension of the hidden torsion bar chassis is arranged inside the round tube through a spring steel plate, which is not easily bumped and will not be damaged by debris such as stones and soil. The suspension system can be more durable and the suspension reliability is better.

[0017] 2. In the present invention, a spring steel plate is arranged in the slot of the cantilever. When the wheel hub is impacted by the road surface, the deformation of the torsion arm will drive the spring steel plate to elastically deform. The elastic restoring force of the spring steel plate itself is used to resist the deformation of the torsion arm, thereby achieving the functions of buffering and shock absorption.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-4, the utility model provides an embodiment: a hidden torsion bar chassis front suspension, including two round tubes 1, the two round tubes 1 are arranged up and down, and cantilevers 2 are provided at the centers of both side walls of the two round tubes 1. Bearings 4 are provided at the upper and lower centers of the two cantilevers 2. A clamping groove 6 is provided at the upper and lower centers of one side wall of the two cantilevers 2. A spring steel plate 5 is provided at the centers of the two round tubes 1. A torsion arm 3 is provided at the upper and lower centers of one side wall of the two cantilevers 2. When the vehicle body carries heavy objects or travels on bumpy roads, the wheel hub is subjected to impact force from the ground, and the impact force is transmitted to the torsion arm 3, causing the torsion arm 3 to generate torsional motion. The torsional motion of the torsion arm 3 is transmitted to the round tube 1 through the cantilever 2. Due to the internal The bearing 4 on the top makes the transmission process smoother. At the same time, the impact force will also cause the spring steel plate 5 on the cantilever 2 to deform. The spring steel plate 5 is stuck in the slot 6 to ensure that the position is relatively stable during the deformation process. The deformation of the spring steel plate 5 can absorb and buffer part of the impact force and play a role in shock absorption. As the impact force changes, the torsion arms 3 on both sides will twist, causing the spring steel plate 5 to float up and down inside the round tube 1. This up and down floating further absorbs and disperses the impact force to ensure the stability of the vehicle body. When the impact force disappears, the spring steel plate 5 returns to its original shape under the action of its own elasticity, the torsion arm 3 also returns to its initial position, and the wheel hub returns to a suitable position, thereby ensuring the driving stability of the vehicle under different road conditions.

[0027] The two spring steel plates 5 are respectively adapted to the four slots 6. When the wheel hub is impacted by the road surface, the torsion arm 3 is deformed, and the spring steel plate 5 in the slot 6 will also undergo elastic deformation. The spring steel plate 5 resists the deformation of the torsion arm 3 by its own elastic restoring force, thereby playing a role in buffering and shock absorption. A connecting hole is provided on one side of the center of the upper end surface of the four torsion arms 3 for connecting other components, such as a steering mechanism or a braking system. A wheel hub is provided on one side of the two torsion arms 3. When the vehicle is traveling on the road, the wheel hub is subjected to the force of the road surface. These forces are transmitted to the torsion arm 3 through the connecting device. The torsion arm 3 undergoes a certain degree of torsion and deformation under the action of the force, and at the same time transmits the force to the spring steel plate 5. The two round tubes 1 are made of stainless steel. As the main supporting structure of the suspension system, the round tube 1 needs to have sufficient strength and rigidity to withstand the weight of the vehicle and various forces during driving. The stainless steel material has high strength and hardness, which can meet the mechanical performance requirements of the round tube 1.

[0028] Working principle: When the vehicle body carries heavy objects or travels on bumpy roads, the wheel hub is subjected to impact force from the ground, and the impact force is transmitted to the torsion arm 3, causing the torsion arm 3 to produce torsional motion. The torsional motion of the torsion arm 3 is transmitted to the round tube 1 through the cantilever 2. Due to the action of the bearing 4 inside the cantilever 2, this transmission process is smoother. At the same time, the impact force will also cause the spring steel plate 5 on the cantilever 2 to deform, and the spring steel plate 5 is stuck in the slot 6 to ensure that the position is relatively stable during the deformation process. The deformation of the spring steel plate 5 can absorb and buffer part of the impact force and play a shock-absorbing role. As the impact force changes, the torsion arms 3 on both sides will twist, causing the spring steel plate 5 to float up and down inside the round tube 1. This up and down floating further absorbs and disperses the impact force to ensure the stability of the vehicle body. When the impact force disappears, the spring steel plate 5 returns to its original state under its own elastic action, the torsion arm 3 also returns to its initial position, and the wheel hub returns to the appropriate position, thereby ensuring the driving stability of the vehicle under different road conditions.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
