One end is connected to the transmission body, and the other end suspends the clutch actuator. The total weight of the actuator can reach about 7kg. Generally, its structural design mainly considers the load-bearing capacity, so it will be as follows Figure 1 The integral plate structure shown is mainly designed as A, and its weight is too heavy to meet the requirements of lightweight. At the same time, it fails to fully take into account the random vibration and simple harmonic vibration fatigue strength specifications, resulting in fatigue life in certain directions in the vibration fatigue test not meeting the requirements. In addition, the integral plate structure and other components are not compatible in assembly, resulting in other components such as wiring harnesses not being arranged well, and it is not conducive to the heat dissipation of the gearbox and actuator, which can easily cause excess heat in the mechanism and pose potential risks. These problems are relatively common. They are issues that need to be considered during design.

Example 1

[0025] The weight of the actuator assembly is equivalent to being concentrated at the center of mass, constraints are imposed on the transmission main body area, non-identical parts are connected in the support plate, and the entire model is subjected to gravitational accelerations of 15g forward, 15g downward, and 15g rightward. The strength simulation results are analyzed and obtained. It can be concluded from the simulation results that the stress distribution of the bracket is mainly concentrated in the boundary area, and there is almost no stress distribution in the middle area. Therefore, the material in the middle area does not play a substantial load-bearing role and can be removed to obtain the new structure of this embodiment.

[0026] like Figure 2-Figure 3 As shown, the clutch actuator bracket of this embodiment includes a bracket body 1, the outer edge of the bracket body 1 does not fully cover the transmission body, and includes a special-shaped structure surrounded by a curved wall and a straight wall.

The mounting surface 11 is connected to the transmission body, and a mounting hole 13 for cooperating with the clutch actuator is arranged at the outer edge of the mounting surface 11; a vacant portion 2 is hollowed out in the middle area of ​​the bracket body 1, and a reinforcement portion 3 is arranged at the connection between the mounting surface 11 and the transmission body to meet the requirements of random vibration fatigue strength.

The connecting arm A2 is composed of an arc structure and / or a plurality of straight face segment structures. In this embodiment, one connecting arm A2 is an arc structure, and the other is formed by two straight face segment structures.

[0030] In order to optimize the spatial layout of materials, the area of ​​the vacant part 2 of this embodiment accounts for 1 / 4-1 / 2 of the area of ​​the entire bracket body 1. In this embodiment, it accounts for 1 / 4 of the area of ​​the entire bracket body 1. This structure not only meets the strength requirements, but also achieves lightweight and reduces costs. The hollowing size of the vacant part is a scientific result obtained by comprehensive measurement and simulation of materials, loading forces, etc.

[0031] The shape of the vacant portion 2 is designed according to the requirements of the anti-destructive strength under various loads, and the vacant portion 2 is a structure that is wide at the top and narrow at the bottom.

The reinforcement support plate 32 ribs are arranged in a certain direction around the support column 31, which greatly enhances the random vibration life of the bracket.
