[0002] The internal circulation steering gear appropriately transforms the steering torque and steering angle from the steering wheel, and then outputs it to the steering rod mechanism to steer the car, so the steering gear is essentially a reduction transmission device.

[0003] For example, the authorization announcement number "CN220764494U" is an easy-to-maintain internal circulation steering gear. By pushing the positioning frame connected to the extension plate to swing with the pin shaft as the axis, when the positioning frame is sleeved on the surface of the steering gear transmission end, the connection end of the steering gear is squeezed and sealed. It can improve the connection method between the steering screw and the housing of the existing steering gear, and auxiliary oil seals are used for sealing to prevent leakage at the connection between the steering screw and the housing after repeated rotation of the steering screw, thereby avoiding oil loss. However, during the use of the internal circulation steering gear, the internal structure of the internal circulation steering gear is meshed and cooperated with the fan teeth, gear sleeves and steering screws. Multiple structures will directly wear out and will be damaged after long-term use. When maintenance is required, multiple fixed bolts need to be screwed one by one to complete the disassembly of the internal circulation steering gear, which wastes time, reduces the working efficiency of the internal circulation steering gear, and is not convenient for maintenance of the internal circulation steering gear.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings: Example 1

[0021] See also Figure 1-6 In the present embodiment, an internal circulation steering gear which is easy to maintain includes an internal circulation steering gear 1 and a square plate 6. The right ends of the front and rear sides of the internal circulation steering gear 1 are respectively fixedly connected to the inner side of the square plate 6. How to operate and use the internal circulation steering gear 1 is already the prior art and will not be elaborated on. The model is selected according to usage requirements. The tops of the front and rear sides of the internal circulation steering gear 1 are respectively fixedly connected with an outer shell 5, and the inner wall of the outer shell 5 is connected with a control structure 2. A top cover 4 is attached to the top of the internal circulation steering gear 1, and an oil injection structure 3 is connected to the top of the top cover 4, and a circular plate 7 is connected to the bottom of the control structure 2.

[0022] The control structure 2 includes a protruding rod 201 and a bracket 202. The outer wall of the protruding rod 201 is slidably engaged with the bottom of the inner wall of the housing 5. The protruding rod 201 is subjected to force and slides up and down through the bottom of the inner wall of the housing 5. The outer wall end of the protruding rod 201 is slidably engaged with the outer wall oblique groove of the bracket 202. The front and rear sides of the outer wall of the protruding rod 201 can slide in the oblique groove of the outer wall of the bracket 202. A bent rod 203 is fixedly connected to the top of the bracket 202, a straight plate 204 is fixedly connected to the right side of the bracket 202, and a cross bar 203 is fixedly connected to the right side of the straight plate 204. 5. The outer wall of the cross bar 205 is sleeved with a spring 206, and the two ends of the spring 206 are respectively fixed to the right side of the straight plate 204 and the right side of the inner wall of the shell 5. After the straight plate 204 is forced to move to the right, it rebounds by the resilience of the spring 206, and the outer wall of the curved rod 203 is slidably engaged with the top notch of the shell 5. The curved rod 203 is forced to slide left and right through the top notch of the shell 5, and the right side of the outer wall of the cross bar 205 is plugged into the right side of the shell 5, and the inner side of the outer wall of the curved rod 203 is plugged into the outer wall notch of the top cover 4;

[0023] By controlling the circular plate 7 in the control structure 2 to move the protruding rod 201 upward through the outer shell 5, the front and rear ends of the moving protruding rod 201 will slide in the oblique groove of the outer wall of the bracket 202, and the curved rod 203 is slidably engaged with the top of the outer shell 5, so that the bracket 202 can only move to the right, and then move the curved rod 203 to the right at the top of the outer shell 5, so that the inner end of the curved rod 203 moves to the right in the groove of the outer wall of the top cover 4. When the curved rod 203 slides to the right end of the groove of the outer wall of the top cover 4, the top cover 4 is lifted upward, and then the interior of the inner circulation steering gear 1 can be maintained, thereby improving the working efficiency of the inner circulation steering gear and facilitating the maintenance of the inner circulation steering gear.

[0024] The bottom of the protruding rod 201 is fixedly connected to the top of the circular plate 7. The oil injection structure 3 includes a vertical cylinder 301 and a plug 302. The bottom of the vertical cylinder 301 is connected to the top of the top cover 4. The inner wall of the vertical cylinder 301 is plugged into the outer wall of the plug 302. The plug 302 is a rubber block. The left and right sides of the plug 302 are respectively fixed with curved plates 303. The curved plates 303 facilitate the upward movement of the plug 302.

[0025] Working principle:

[0026] Installation and use of internal circulation steering gear:

[0027] The right steering screw of the inner circulation steering gear 1 is connected to the rotation controller of the vehicle body. At this time, the square plate 6 will fit with the connection. Then the bolts are threaded through the square plate 6 from right to left and fixed with the connection threads. Then the vehicle body connector is plugged into the rotating shaft at the bottom of the front side of the inner circulation steering gear 1. The hand fits the bottom of the curved plate 303 and pushes it upward. The curved plate 303 is forced to move the plug 302 upward, so that the plug 302 is separated from the inside of the vertical cylinder 301. Then the lubricating oil is poured through the vertical cylinder 301, and then the plug 302 is inserted back into the vertical cylinder 301 for sealing.

[0028] Internal circulation steering gear maintenance:

[0029] The hand pushes the circular plate 7 upward, and the circular plate 7 moves upward through the shell 5 with the convex rod 201. The front and rear ends of the moving convex rod 201 slide in the oblique groove of the outer wall of the bracket 202. In addition, the curved rod 203 is slidably engaged with the top of the shell 5, and the bracket 202 can only move to the right, and then the curved rod 203 moves to the right at the top of the shell 5, so that the inner end of the curved rod 203 moves to the right in the groove of the outer wall of the top cover 4. When the curved rod 203 slides to the right end of the groove of the outer wall of the top cover 4, the top cover 4 is lifted upward. Then the interior of the inner circulation steering gear 1 can be maintained. The bracket 202 moves and cooperates with the straight plate 204 to squeeze the spring 206. After the maintenance is completed, the top cover 4 is fitted with the top of the inner circulation steering gear 1, and the round plate 7 is loosened. The spring 206 provides a rebound force, so that the straight plate 204 moves to the left with the bracket 202, so that the bracket 202 moves to the left with the bent rod 203, so that the bent rod 203 is clamped with the left side of the inner wall of the groove on the outer wall of the top cover 4, and the top cover 4 and the inner circulation steering gear 1 are fixed. Example 2

[0030] See also Figure 1-6 : In this embodiment, an internal circulation steering gear that is easy to maintain also includes a sleeve 8 and a ridge 9. The inner wall of the sleeve 8 is threadedly connected to the outer wall of the front rotating shaft of the internal circulation steering gear 1, and the upper and lower sides of the sleeve 8 are respectively fixedly connected to the inner side of the ridge 9.

[0031] Working principle:

[0032] When the vehicle body is plugged into the inner wall of the front shaft of the inner circulation steering gear 1, the sleeve 8 is threadedly connected to the outer wall of the shaft, and the sleeve 8 cooperates with the ridge 9 to be plugged into the connection between the vehicle body, thereby increasing the connection form of the inner circulation steering gear 1.
