With the continuous increase of the requirements of users for intelligent driving, the requirements of automobile manufacturers for vehicle motorization and integration are increasing. The electronic mechanical brake system (EMB) has the characteristics of small volume, simple structure, quick response, accurate pressure regulation and the like, and is more beneficial to realizing intelligent driving, so that the EMB has higher research value and is a main direction of the development of a future brake system.

Based on the above problems, the embodiment of the invention provides a steering knuckle, a steering knuckle assembly and a vehicle, which can respectively assemble an electromechanical brake and a conventional brake aiming at the same brake disc so as to perform the work of the electromechanical brake real vehicle test and the reliability analysis and ensure the safety of the vehicle.
A knuckle, a knuckle assembly, and a vehicle according to embodiments of the invention are described below with reference to fig. 1 to 7.
As shown in fig. 1 to 6, a knuckle 100 according to an embodiment of the present invention includes a knuckle body 110, a first mounting structure, and a second mounting structure. It will be appreciated that the knuckles 100 on the left and right sides of the vehicle are symmetrically disposed. In the present embodiment, a state in which the left knuckle 100 is mounted to the vehicle will be described as an example. The knuckle 100 has a front-rear direction, a left-right direction, and an up-down direction.
The knuckle body 110 has a fitting hole 160, the axial direction of the fitting hole 160 extending in the left-right direction, the fitting hole 160 serving to mount the brake disc 400. The fitting hole 160 is a circular hole, preferably a stepped circular hole.
The first mounting structure is used for mounting a first brake, which is an electromechanical brake, and is fixedly connected with the knuckle main body 110. The second mounting structure is used for mounting a second brake, and the second brake can be a hydraulic brake or a pneumatic brake or an electromagnetic brake. The second mounting structure is fixedly coupled to the knuckle body 110. Further, the first mounting structure and the second mounting structure are disposed at regular intervals around the circumferential direction of the fitting hole 160.
It is appreciated that the first and second mounting structures may be attached to the knuckle body 110 by welding, an integral die casting process, or the like. In the present embodiment, the second mounting structure is preferably used for mounting of the hydraulic brake.
In the knuckle 100 provided in this embodiment, the mounting hole 160 on the knuckle body 110 may provide a mounting position for the brake disc 400, the first mounting structure on the knuckle body 110 may provide a mounting position for the electromechanical brake, and the second mounting structure on the knuckle body 110 may provide a mounting position for a hydraulic, pneumatic or electromagnetic brake that is mature in technology, so that the electromechanical brake and a conventional brake can be respectively mounted on the same brake disc 400 on the knuckle body 110, so as to collect data in a test vehicle, thereby completing the real vehicle test and reliability analysis of the electromechanical brake, improving the test accuracy of the electromechanical brake, and enabling another brake when the electromechanical brake fails, effectively ensuring the safety of vehicles and personnel through the other brake, and further accelerating the research progress of the electromechanical brake system.
It will be appreciated that the knuckle 100 of the above-described structure can be used for testing a vehicle while simultaneously assembling two different types of brakes, an electromechanical brake and a conventional brake, so as to facilitate the analysis of the operational reliability of the mechanical structure and the control system of the EMB system while ensuring the safety of the tested vehicle. Two sets of brakes are configured for a period of time after EMB system real-vehicle testing and formal marketing, so that the safety of personnel and vehicles can be ensured.
In some embodiments, as shown in fig. 1 to 6, the first mounting structure includes two first mounting ears 170, each first mounting ear 170 being provided with a first mounting hole, the first mounting hole serving to connect with the first brake. The two first mounting ears 170 are spaced apart and fixedly coupled to the knuckle body 110. The first mounting holes may be circular holes to fix the first stopper to the two first mounting ears 170 by bolts.
The second mounting structure includes two second mounting lugs 180, and each second mounting lug 180 is provided with a second mounting hole, and the second mounting holes are used for being connected with the second brake. The two second mounting ears 180 are spaced apart and fixedly coupled to the knuckle body 110. The second mounting holes may be circular holes to fix the second brake to the two second mounting ears 180 by bolts.
Compared with the method that two mounting holes are simultaneously arranged on the same mounting part of the knuckle 100 to mount the brake, the first mounting structure and the second mounting structure adopting the structure can reduce the total weight of the knuckle 100, realize the light weight of the knuckle 100, and simultaneously facilitate the knuckle 100 to swing easily under the driving action of the steering gear, and lighten the load of the steering gear.
In some examples, as shown in fig. 1 to 6, two first mounting holes are arranged at regular intervals around the circumference of the fitting hole 160 on the knuckle body 110, two second mounting holes are arranged at regular intervals around the circumference of the fitting hole 160 on the knuckle body 110, and the axial direction of the first mounting holes, the axial direction of the second mounting holes, and the axial direction of the fitting hole 160 are disposed in the same direction.
It is understood that the centers of the two first mounting holes are all distributed on the same circle of the assembly hole 160, and the centers of the two second mounting holes are all distributed on the same circle of the assembly hole 160. And, all the first mounting holes and all the second mounting holes are located on the same circle of the assembly holes 160.
Of course, it is not excluded that the centers of the two first mounting holes are not on the same circle of the mounting hole 160, and that the centers of the two second mounting holes are not on the same circle of the mounting hole 160.
In a preferred example, as shown in fig. 1 to 6, a vertical line between the central axes of the two first mounting holes is set as a first line segment, a midpoint of the first line segment is set as a first midpoint, a vertical line between the central axes of the two second mounting holes is set as a second line segment, and a midpoint of the second line segment is set as a second midpoint. In this embodiment, the first midpoint is point B, and the second midpoint is point a.
In the case where all the first mounting holes and all the second mounting holes are distributed on the same circle of the mounting hole 160, a vertical distance between the first midpoint and the central axis of the mounting hole 160 is set to L4, a vertical distance between the second midpoint and the central axis of the mounting hole 160 is set to L1, a length of the first line segment is set to L3, and a length of the second line segment is set to L2. In the present embodiment, l1=l4, l2=l3.
With the above structural arrangement, the positions of the first mounting ear 170 and the second mounting ear 180 are reasonably arranged on the knuckle main body 110, so that the overall strength and rigidity of the knuckle 100 can be improved, the weight of the knuckle 100 is reduced, and simultaneously, the two brakes are stably mounted on the same knuckle 100.
Of course, other embodiments are not precluded from employing structural designs where L1 and L4 are not equal, and L2 and L3 are not equal.
Further, as shown in fig. 1 to 6, the center of the mounting hole 160 is set as the O point, the horizontal plane 500 passing through the center of the mounting hole 160 is set as the reference plane, the horizontal plane 500 is perpendicular to the up-down direction, the vertical line between the first midpoint (i.e., the B point) and the central axis of the mounting hole 160 is set as the first line, and the vertical line between the second midpoint (i.e., the a point) and the central axis of the mounting hole 160 is set as the second line.
On the basis that all the first mounting holes and all the second mounting holes are distributed on the same circle of the mounting hole 160, l1=l4 and l2=l3, the first connecting line forms a first included angle with the reference plane, the first included angle is 0-2 degrees, the second connecting line forms a second included angle with the reference plane, and the second included angle is 20-22 degrees. Moreover, the first midpoint is located within or below the reference plane and the second midpoint is located above the reference plane.
As shown in fig. 6, in one example, the first included angle is 0 °, i.e., the first midpoint (i.e., point B) is located in the reference plane. The second included angle is set as theta, the theta takes a value in an angle range of 20 degrees to 22 degrees, and the second midpoint (namely point A) is positioned above the reference plane.
Preferably, the first angle is 0 ° 23', the second angle θ is 21 ° 41', the first midpoint is below the reference plane, the second midpoint is above the reference plane, and l1=l4=117.5 mm, l2=l3=125.5 mm. Because the second brake on the second mounting structure is exhausted, and the first brake on the first mounting structure is driven by the motor and has no exhaust mounting angle requirement, the knuckle 100 is arranged in such a structure that the knuckle 100 structure can be optimized under the condition of simultaneously carrying the first brake and the second brake, and the space positions of the first brake on the first mounting structure and the second brake on the second mounting structure are reasonably arranged, so that after the knuckle 100 is mounted on a vehicle, the first brake and the second brake do not interfere with each other, and meanwhile, the first brake and the second brake do not interfere with the peripheral parts of the knuckle 100, and the knuckle 100 is ensured to have high strength and rigidity and optimal stress direction, so that the knuckle 100 structure is lighter and easy to realize.
As shown in fig. 7, through CAE (english full name Computer-Aided Engineering Simulation Analysis) simulation analysis, the knuckle 100 adopts the above structural design, and the strength and rigidity of the knuckle can meet the requirements, are not easy to deform or break, and the structure is lighter, and can meet the installation requirements and stability of two brakes, and well solve the problem of wheel space arrangement under the design of the double brakes of the EMB and the conventional brake; moreover, the requirements of vehicle dynamoelization, intelligent driving and integration can be met.
Of course, it is not excluded that L1, L2, L3, L4, the first angle and the second angle may take other values.
