Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and in particular relates to an automotive steering gear housing structure. Background Technology

[0002] The function of the steering gear is to appropriately transform the steering torque and steering angle from the steering wheel and then output them to the steering tie rod mechanism, thereby turning the car. Therefore, the steering gear is essentially a speed reduction transmission device.

[0003] Existing technologies disclose several utility model patents in the field of automotive parts technology. Among them, utility model patent application number CN220465606U discloses a protective housing structure for an automotive steering gear, including a protective housing body, a hydraulic pump, and a pull rod. The hydraulic pump is fixed at both ends of the protective housing body, and the pull rod is rotatably connected inside the protective housing body. A protective cover is provided at the end of the hydraulic pump away from the protective housing body, and a first sealing gasket is provided between the facing surfaces of the hydraulic pump and the protective cover. The first sealing gasket improves the seal during the installation of the protective housing body. Firstly, the first sealing gasket can be held and placed at one end of the hydraulic pump. Then, the first sealing gasket can cooperate to insert a second sealing gasket into a slot opened in the hydraulic pump. At this time, the protective cover can be held to move the slot onto the surface of the second sealing gasket, achieving a better sealing effect and preventing poor sealing of the protective housing body from causing impurities to enter and affect the overall protective effect.

[0004] The drawback of existing technology is that after a period of use, dust and impurities accumulate in the gap between the protective cover and the steering gear body, making it difficult to clean and causing the device to jam during use.

[0005] Based on this, the present invention designs a car steering gear housing structure to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that dust and impurities in the gap between the protective cover and the steering gear body are difficult to clean and can easily cause jamming during use. Therefore, a new automotive steering gear housing structure is proposed.

[0010] The cleaning assembly includes a piston cylinder fixedly connected to the top of a first protective cover and the bottom of a second protective cover. A piston rod is slidably connected inside the piston cylinder, and the bottom of the piston cylinder is connected to two fixed pipes.

[0011] As a further description of the above technical solution:

[0012] Both ends of the two fixed pipes are connected to fixed airbags, and the fixed airbags are provided with several one-way air jets.

[0013] As a further description of the above technical solution:

[0014] Both ends of the first and second protective covers are provided with slots, and the size of the slots is the same as that of the fixed airbag.

[0015] As a further description of the above technical solution:

[0016] The fixed pipe is L-shaped and is snapped into the corresponding first and second protective covers.

[0017] As a further description of the above technical solution:

[0018] The piston cylinder is connected to a one-way air intake valve, and the top of the piston rod is provided with a pressing handle.

[0019] As a further description of the above technical solution:

[0020] The sealing strip is slidably connected in the sealing groove, and the fixed pipe is connected to the first protective cover and the second protective cover respectively.

[0021] As a further description of the above technical solution:

[0022] The first protective cover and the second protective cover fit together, and the support block is L-shaped.

[0023] As a further description of the above technical solution:

[0024] One end of the threaded post is slidably connected in the corresponding fixing hole, and the other end of the threaded post is provided with a fixing handle.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0026] 1.
