[0002] The automobile thrust rod is mainly used for preventing the displacement of the vehicle axle, and ensures the stability and safety of vehicle driving. It is an important component connecting the vehicle frame and the vehicle axle, and can transmit the traction, braking force and the corresponding reaction torque between the vehicle frame and the vehicle axle, thereby making up for the defects of insufficient transmission in some directions of the steel plate spring.

[0003] The existing thrust rod is mainly divided into two kinds, one is a cylindrical rod, and the other is an I-shaped rod. The cylindrical rod has good strength, but the manufacturing cost and manufacturing time are relatively long. The I-shaped rod greatly reduces the manufacturing cost and manufacturing time under the condition of having relatively good strength, but its strength performance still has certain gap compared with the cylindrical rod. For example, under some extreme working conditions or high load conditions, the I-shaped rod can not meet the strict requirements of the vehicle on the strength of the thrust rod, and therefore a new scheme is needed to improve this situation.

[0017] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, and in the description of the utility model, it should be understood that the orientation or position relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0018] A high-strength push rod, such as Figures 1-4As shown, the I-beam body 1 and the core seat 2 integrally formed at both ends of the I-beam body 1, the I-beam body 1 includes the weight-reducing groove 3 arranged on both sides, which forms the I-beam cross-section modeling through the weight-reducing groove 3, while reducing the weight, also ensures a certain strength, and the weight-reducing groove 3 is provided with a plurality of reinforcing ribs 4, the reinforcing ribs 4 are horizontal and perpendicular to the side wall of the weight-reducing groove 3, and both ends are connected with the side wall of the weight-reducing groove 3 respectively, so that under the action of the reinforcing ribs 4, the cross-sectional moment of inertia of the I-beam body 1 is increased, thereby improving its stiffness, so that the I-beam body 1 can resist deformation more, and the resistance to pressure or torque applied or generated on its side will be improved, thereby adapting to a higher load environment.

[0019] The reinforcing rib 4 includes a fillet end 6 and a flat top 7, wherein the fillet end 6 is on both sides of the top of the reinforcing rib 4, the structure of the fillet can not only better disperse the stress point when it is collided by external objects to reduce the probability of damage, but also can disperse the stress point generated on the top of the reinforcing rib 4 due to pushing during use, thereby reducing stress concentration and further reducing the probability of damage and improving strength, while the flat top 7 can increase the stress surface, thereby increasing the dispersion area of the compressive stress and further increasing the strength.

[0020] The radius of the fillet end 6 is greater than the width of the flat top 7, so as to ensure that the stress dispersion of the reinforcing rib 4 reaches the best effect, and the bottom reinforcing arc edge 8 is further arranged between the fillet end 6 and the bottom surface of the weight-reducing groove 3, so that the stress generated at the connection between the reinforcing rib 4 and the bottom of the weight-reducing groove 3 can be more effectively dispersed, thereby further increasing the strength, and the reinforcing rib 4 is at least two and uniformly arranged and distributed, so as to ensure the increasing effect on the strength of the I-beam body 1.

[0021] The edge of the reinforcing rib 4 and the side wall of the weight-reducing groove 3 are provided with a side reinforcing arc edge 5, the side reinforcing arc edge 5 can increase the connection area of the reinforcing rib 4 and the I-beam body 1, and increase the dispersion degree of the stress at the connection, thereby increasing the strength; the radius of the side reinforcing arc edge 5 is equal to the radius of the fillet end 6, and the radian is 60-90 degrees, if the side reinforcing arc edge 5 is too small, it may cause stress concentration and increase the stress risk of the connection part, thereby reducing the connection strength, therefore, the side reinforcing arc edge 5 with a suitable size can better increase the strength, and the height of the reinforcing rib 4 is less than half the depth of the weight-reducing groove 3, so as to ensure that there is enough space to arrange the side reinforcing arc edge 5.
