Description

Technical Field

[0001] This utility model belongs to the field of testing tooling technology, specifically relating to a steering gear damping grease aging test device. Background Technology

[0002] The steering gear is a core component of the steering system in vehicles such as automobiles and construction machinery. Its function is to transmit the driver's force on the steering wheel to the wheels, controlling the vehicle's direction of travel. Damping grease (also known as steering damping grease or lubricating grease) is typically added to the steering gear, mainly applied to several key areas such as gears, racks, and shaft joints, to ensure smooth operation of the steering system and reduce wear. This has a significant impact on the smoothness, stability, and lifespan of the steering system.

[0003] However, damping grease will gradually age due to factors such as temperature, mechanical shear, oxidation and contamination during long-term use, resulting in a decline in performance, which in turn affects steering feel, noise control and component wear.

[0004] Therefore, how to provide a testing device that can simulate the aging process and perform accelerated aging on multiple steering gear damping greases in order to test the durability and service life of the damping grease is a technical problem that urgently needs to be solved by those skilled in the art.

Each test mechanism 2 includes a transmission wheel 21, a motor shaft 22, and a quick clamp 23. The transmission wheel 21 is located in the transmission space. One end of the motor shaft 22 is connected to the transmission wheel 21, and the other end of the motor shaft 22 passes through the top plate 11 and is inserted into the corresponding steering gear limit box 3, and is connected to the gear shaft 31 inside the steering gear limit box 3.

The drive component 13 is connected to the transmission wheel 21.

[0043] Specifically, this utility model provides a steering gear damping grease aging test device for testing the damping grease inside the steering gear limit box 3. It includes a servo control box 1 and several test mechanisms 2. The servo control box 1 includes a top plate 11 and a bottom plate 12, forming a transmission space between them. The servo control box 1 contains a servo controller, a controller assembly, and a drive component 13, which is a motor reducer assembly used to drive the test mechanisms 2. Several test mechanisms 2 are symmetrically arranged in two rows in the middle of the top plate 11, allowing for simultaneous damping grease aging tests on multiple steering gears. Each test mechanism 2 includes a transmission wheel 21, a motor shaft 22, and a quick clamp 23. The transmission wheel 21 is located within the transmission space. A motor shaft 22 is provided in the middle of the rotating wheel 21, and a through hole is provided in the top plate 11 at the corresponding position of each motor shaft 22, so that one end of the motor shaft 22 passes through the top plate 11 and is inserted into the gear shaft 31 of the corresponding steering gear limit box 3, thereby driving the gear inside the steering gear limit box 3 to rotate, simulating the rotation process of the gear inside the steering gear and the aging process of the damping grease during actual use, and testing the degree of aging of the damping grease inside the steering gear limit box 3; the quick clamp 23 is connected to the top surface of the top plate 11 and is used to quickly clamp and fix the steering gear limit box 3 on the top plate 11; in this way, a test device that can simulate the aging process and perform the same accelerated aging on multiple steering gear damping greases is constructed to test the durability and service life of the damping grease.

[0044] In some possible implementations, a primary linkage gear 24 is meshed between the two end transmission wheels 21 in the two rows of transmission wheels 21, and the primary linkage gear 24 is connected to the drive member 13; a secondary linkage gear 25 is meshed between two adjacent transmission wheels 21 in the same row of transmission wheels 21.

[0045] Specifically, such as Figure 2 As shown, the transmission wheels 21 are arranged in two rows. The two transmission wheels 21 at the end of the two rows are connected by a primary linkage gear 24. The primary linkage gear 24 is connected to the drive component 13, thereby driving the transmission wheels 21 in the two rows through the primary linkage gear 24. The two adjacent transmission wheels 21 in the same row are connected by a secondary linkage gear 25, which can rotate the transmission wheel 21 that is engaged with the primary linkage gear 24 to drive it backward and drive all the transmission wheels 21 to rotate.

[0046] In some possible implementations, the first-stage linkage gear 24 and the second-stage linkage gear 25 are the same size.

[0047] Specifically, the first-stage linkage gear 24 and the second-stage linkage gear 25 are the same size, so that the transmission ratio between the first-stage linkage gear 24 and the second-stage linkage gear 25 and the transmission wheel 21 is the same, and the rotation speed among all transmission wheels 21 is kept the same.

[0048] In some possible implementations, the top plate 11 and the bottom plate 12 are connected by a number of support rods 14; the top plate 11 has a number of sets of mounting holes 111, and a number of quick clamps 23 are detachably mounted on the top plate 11 through the corresponding mounting holes 111.

[0049] Specifically, as shown in the figure, the top plate 11 and the bottom plate 12 are connected by several support rods 14 to maintain the stability of the bottom plate 12.

[0050] In some possible implementations, the quick clamp 23 includes a main body, an operating handle, and a pressure block. The main body is detachably mounted on the mounting hole 111. When the operating handle is pressed down, the pressure block abuts against the top surface of the steering gear limit box 3, and the bottom surface of the steering gear limit box 3 abuts against the top surface of the top plate 11.

[0051] Specifically, by setting up the quick clamp 23, the steering gear limit box 3 can be stably clamped onto the top plate 11.

[0052] In some possible implementations, the steering gear damping grease aging test device also includes a Hall encoder 15, which is mounted on the bottom of the base plate 12 via a fixing plate 16; the Hall encoder 15 is connected to an adapter rod, which passes through the base plate 12 and is connected to any of the drive wheels 21.

[0053] Specifically, such as Figure 2 As shown, the Hall encoder 15 is connected to the rotating wheel 21 via an adapter rod, so that the Hall encoder 15 is driven by the rotation of the transmission wheel 21 to accurately calculate and record the rotation speed of the transmission wheel 21, which is convenient for subsequent measurement of the aging degree of the steering gear damping grease under different simulated intensity conditions.

[0054] In some possible implementations, the servo control box 1 is also provided with a maintenance door 17, one side of which is rotatably connected to the servo control box 1, and the other side of which is connected to the servo control box 1 by a latch.

[0055] Specifically, as shown in the figure, the test of the maintenance door 17 facilitates the operator's later disassembly or maintenance of the servo control box 1.
