Description

Technical Field

[0001] The invention belongs to the field of vehicle axles, and in particular relates to a vehicle axle for a new energy vehicle. Background Art

[0002] Compared with traditional fuel vehicles, new energy vehicles have the advantages of safe and clean energy, less pollution emissions, and lower noise. They are currently developing rapidly and are widely used. The design of new energy vehicles is mostly compact, and precision core components such as batteries, motors, and electronic control systems are mostly installed on the chassis and axles of the vehicle. They are sensitive to vibration and impact, requiring new energy vehicles to have better shock absorption performance and body support effects. The biggest resistance for vehicles traveling on highways comes from wind resistance. Lowering the body can effectively reduce wind resistance and increase the endurance of new energy vehicles. Different road conditions such as highways, urban roads, mountain roads, etc. require different body heights and spring shock absorption effects to cope with them. Most new energy vehicles on the current market have a single fixed shock absorption intensity, which makes it difficult to cope with complex and changeable road conditions. Summary of the invention

[0003] The purpose of the present invention is to provide a new energy vehicle axle to solve the problem that the design of new energy vehicles is mostly compact, and the precision core components such as batteries, motors, and electronic control systems are mostly arranged on the chassis and axle positions of the vehicle, which are sensitive to vibration and impact. The new energy vehicles are required to have better shock absorption performance and body support effect. The greatest resistance of vehicles traveling on highways comes from wind resistance. Lowering the body can effectively reduce wind resistance and increase the endurance of new energy vehicles. Different road conditions such as highways, urban roads, mountain roads, etc. require different body heights and spring shock absorption effects to cope with them. At present, most new energy vehicles on the market have a single fixed shock absorption strength, which is difficult to cope with the technical problem of complex and changeable road conditions.

[0004] To achieve the above purpose, the specific technical solution of a new energy vehicle axle of the present invention is as follows:

[0005] A new energy vehicle axle includes a main body and two wheel hub steering knuckle assemblies and a connecting frame, a pull rod, a stabilizer bar, and an upper connecting rod connected therebetween, characterized in that the connecting frame is rotatably arranged on both sides of the lower body; a spring shock absorber is rotatably arranged on the top of the main body toward the position of the connecting frame; a slide groove is arranged on the connecting frame at a position close to the spring shock absorber; a connecting column is slidably arranged in the slide groove; a rotatable connection is adopted between the spring shock absorber and the connecting column; a cylinder is arranged on the connecting frame on both sides of the spring shock absorber opposite to each other; a cylinder head is arranged in the cylinder and connected to the opposite end of the connecting column.

[0006] Furthermore, a stabilizing spring is arranged between the side of the cylinder head away from the cylinder and the connecting frame.

[0007] Furthermore, a support seat ring is arranged at one end of the spring shock absorber close to the connecting frame.

[0008] Furthermore, the connecting frame is provided with upwardly curved arc-shaped push blocks on both sides of the supporting seat ring.

[0009] Furthermore, the wheel hub steering knuckle assemblies on both sides are arranged in relative positions and at fixed heights.

[0010] The new energy vehicle axle of the present invention has the following advantages: a spring shock absorber is arranged between the main body and the connecting frame of the new energy vehicle axle to buffer and absorb shock to the vehicle main body; a connecting column is arranged at one end of the spring shock absorber in the slide groove of the connecting frame, and the cylinder and cylinder head arranged on both sides thereof are used to control the connecting column to slide in the connecting frame, thereby controlling the angle between the spring shock absorber and the main body, adjusting the supporting effect of the spring shock absorber, and adjusting the height of the main body on the basis of the wheel hub steering knuckle assemblies at both ends remaining stationary, thereby achieving the function of adjusting the height of the new energy vehicle body, so that the new energy vehicle can adjust its own height according to the road conditions. For example, on roads with high road flatness and high driving speeds such as highways, the cylinder head can be used to push the cylinder head outward, so that the spring shock absorber and the connecting column slide in the slide groove away from the main body, thereby reducing the height of the main body while the position of the wheel hub steering knuckle assembly remains unchanged, thereby achieving the effect of reducing the height of the new energy vehicle, thereby The wind resistance of the vehicle is reduced when it is driving at high speed, and energy loss is reduced. When encountering rugged and bumpy road conditions, the height of the vehicle body can be raised to reduce the possibility of contact between the chassis and electrical core components and the ground, thereby increasing the vehicle's passability and reducing the risk of damage. By selectively adjusting the vehicle height according to road conditions, the vehicle's adaptability to various road conditions is increased; by cooperating with the arc-shaped push blocks set on both sides of the support seat ring of the spring shock absorber close to one end of the connecting frame, the cylinder and the cylinder head cooperate to push the connecting column to slide in the slide groove to drive the spring shock absorber to move. The arc-shaped push block will push the support seat ring to slide on the spring shock absorber, compressing or releasing the space of the spring, thereby realizing the function of adjusting the shock absorbing support effect of the spring shock absorber, and cooperating with the function of adjusting the vehicle body height, the road applicability of new energy vehicles is further increased, the ride comfort is improved, the passability is improved, and the wind resistance and energy loss are reduced.
