It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0017] like Figure 1 As shown, a test device for an electronic parking actuator proposed in an embodiment of the utility model includes: a base 1, a first bracket 2, a second bracket 3, a sleeve tool 4, a first coupling 5, a second coupling 6, a torque sensor 7, a force sensor 8, and a caliper mechanism 9;
[0018] The first bracket 2 and the second bracket 3 are installed on the base 1 and are separated by a distance; the torque sensor 7 is located between the first bracket 2 and the second bracket 3; one end of the sleeve fixture 4 is connected to the outside of the first bracket 2, and the other end is used to connect the electronic parking actuator a1 to be measured; a first connecting shaft is provided in the sleeve fixture 4, one end of the first connecting shaft is used to connect the output end of the electronic parking actuator a1, and the other end passes through the first bracket 2 and is connected to one end of the first coupling 5; the other end of the first coupling 5 is connected to one end of the second connecting shaft, the other end of the second connecting shaft is connected to one end of the torque sensor 7, the other end of the torque sensor 7 is connected to one end of the third connecting shaft, the other end of the third connecting shaft is connected to one end of the second coupling 6, and the other end of the second coupling 6 is connected to one end of the fourth connecting shaft; the other end of the fourth connecting shaft passes through the second bracket 3 and is connected to the input end of the caliper mechanism 9; the caliper mechanism 9 is fixed on the outside of the second bracket 3;
[0019] The force sensor 8 is placed between the operating portion 901 and the fixing portion 902 of the caliper mechanism 9 .
[0020] When the electronic parking actuator a1 is tested, its housing is connected to the other end of the sleeve fixture 4; the output end of the electronic parking actuator a1 is connected to one end of the first connecting shaft; when the output end of the electronic parking actuator a1 rotates, it drives the first connecting shaft, the first coupling 5, the second connecting shaft, the sensing part inside the torque sensor 7, the third connecting shaft, the second coupling 6 and the fourth connecting shaft to rotate in sequence; when the fourth connecting shaft rotates, it drives the caliper mechanism 9 to move; the action part 901 of the caliper mechanism 9 moves closer to the fixed part 902 and clamps the force sensor 8; the torque sensor 7 and the force sensor 8 can send torque signals and clamping force signals to the upper computer through the acquisition card; the upper computer can measure the torque that the electronic parking actuator a1 can output and the clamping force generated by the caliper mechanism after it drives the caliper mechanism to move.
[0021] Furthermore, a speed encoder 10 is installed on the first connecting shaft; when the output end of the electronic parking actuator a1 rotates, the speed encoder 10 on the first connecting shaft connected thereto can feed back a speed signal to the upper computer.
[0022] Furthermore, a first bearing is installed on the first bracket 2, and the first connecting shaft is mounted on the first bracket 2 through the first bearing; the first bearing on the first bracket 2 can make the first connecting shaft rotate flexibly, and will not cause wear due to friction with the first bracket 2 during long-term operation.
[0023] Furthermore, a second bearing is installed on the second bracket 3, and the fourth connecting shaft is mounted on the second bracket 3 through the second bearing; the second bearing on the second bracket 3 enables the fourth connecting shaft to rotate flexibly, and will not wear due to friction with the second bracket 3 during long-term operation.
[0024] Furthermore, the torque sensor 7 is mounted on the base 1 via a sensor support 701; the position of the torque sensor 7 can be fine-tuned via the sensor support 701 so that its two ends are aligned with the second connecting shaft and the third connecting shaft respectively. The torque sensor 7 is a commercially available torque sensor, and its two ends have connecting holes for the rotating shaft respectively.
[0025] Furthermore, one end of the first connecting shaft is provided with an inner hexagonal shaft hole; the output end of the electronic parking actuator a1 is an outer hexagonal shaft end. When the shell of the electronic parking actuator a1 is connected to the other end of the sleeve tooling 4, the output end of the electronic parking actuator a1 spontaneously extends into the inner hexagonal shaft hole at one end of the first connecting shaft.
