Description

Technical Field

[0001] The utility model belongs to the technical field of steering gear disassembly tooling, in particular to a steering gear bearing transmission mechanism disassembly tooling. Background Art

[0002] The steering gear assembly, also known as the steering box or steering gear, is the most important component in a car's steering system. Its function is to increase the force transmitted from the steering wheel to the steering transmission mechanism and change the direction of the force transmission.

[0003] The steering gear is a crucial component of the steering system, serving three primary functions. First, it increases the torque from the steering wheel to a level sufficient to overcome the steering resistance between the steering wheel and the road surface. Second, it reduces the steering shaft's rotational speed, rotating the steering rocker arm shaft, driving the rocker arm to swing and achieve the desired displacement at its end. Alternatively, it converts the rotation of the driving gear connected to the steering shaft into linear motion of the gear rack, achieving the desired displacement. Third, by selecting different thread directions on the worm, the steering wheel's rotation direction is coordinated with the steering wheel's.

[0004] Steering gears typically require a bearing transmission mechanism to transmit power and torque, and the bearing transmission mechanism must be disassembled and repaired during maintenance. For example, Chinese utility model application number CN201721916518.5 discloses a pulling device for disassembling steering gear bearings, comprising a device housing, which is an upright, rod-shaped housing with a hollow interior. A lifting screw is disposed within the housing, and a hole is formed in the top of the housing. The upper end of the lifting screw extends out of the top hole and is connected to a pulling handle. A flat cylindrical guide sleeve is disposed within the lower opening of the housing. The guide sleeve can slide up and down within the housing, and a vertical hole is formed in the center of the guide sleeve. The upper end of an elastic pull head is passed through the central vertical hole of the guide sleeve and connected to the lower end of the lifting screw. The lower end of the elastic pull head is sleeved onto the inner ring of the bearing to be pulled. Utilizing the principle of the elastic pull head and the screw lifting principle, the bearing can be quickly removed, reducing product scrapping costs. By replacing different elastic pull heads, the device can be applied to disassembling various types of bearings. This tool is only suitable for dismantling transmission mechanisms with hollow inner rings of bearings, and is applicable to a limited number of models and structures. It also requires other external tooling to fix and install other parts of the bearing, making it inconvenient to use. Utility Model Content

The following describes an embodiment of the present invention based on its overall structure.

[0032] Example 1

[0033] like Figures 1 to 3 The figure shows a schematic diagram of the structure of a steering gear bearing transmission mechanism disassembly tool, including:

[0034] Base 1; the base 1 is used as a support structure for the entire tooling and can be made of a square steel plate of 10 mm or more; a plurality of columns 11 are provided on the four sides of the base 1; in the present utility model, four columns 11 can be used, distributed at the four corners of the base 1, to serve as the support structure of the entire tooling;

[0035] The card plate 4 is horizontally mounted on the plurality of columns 11. The card plate 4 is a steel plate structure having a shape corresponding to that of the base 1. The columns 11 pass through the four corners of the card plate 4 and are fixedly connected to the card plate 4. The card plate 4 is provided with a first slot 41 for receiving and positioning the lower end of the bearing transmission mechanism 7. That is, the lower and upper ends of the bearing transmission mechanism 7 are press-fitted together by an interference fit, and the lower and upper ends of the bearing transmission mechanism 7 need to be separated.

[0036] Pull plate 3; the pull plate 3 is arranged above the clamping plate 4; a second clamping slot 31 is provided on the pull plate 3; the second clamping slot 31 corresponds to the position of the first clamping slot 41, and is used to place the upper end of the bearing transmission mechanism 7 and clamp it; the second clamping slot 31 corresponds to the position of the first clamping slot 41, so that the lower end and the upper end of the bearing transmission mechanism 7 can be placed in the clamping slots of the clamping plate 4 and the pull plate 3 respectively at the same time, and the clamping position 72 of the lower end of the bearing transmission mechanism is located below the clamping plate 4, and the clamping position 71 of the upper end of the bearing transmission mechanism is located above the pull plate 3.

[0037] Lifting member 2; the lifting member 2 is connected to the pull plate 3 to push the pull plate 3 to move up and down relative to the card plate 4.

[0038] In the present invention, a clamping plate 4 and a pull plate 3 are provided to respectively clamp and fix the two parts of the transmission mechanism that need to be separated, and then the pull plate 3 is pushed away from the clamping plate 4 by the lifting member 2, driving the transmission mechanism to complete the separation. In the present application, as long as there are clamping positions on the two parts that need to be separated, the operation can be carried out. Generally, various raised installation parts or force-bearing parts are provided on mechanical transmission structures, so the solution of the present application is highly applicable. At the same time, the device of the present application is configured with an integrated structure in which the output part and the force-bearing part do not need to be supplemented by other tools. The structure is compact and convenient and flexible to use.

[0039] In a specific implementation, the lifting member 2 is installed on the base 1 and is located between the base 1 and the card plate 4; a lifting end is provided on the lifting member 2 to fully utilize the space between the base 1 and the card plate 4, making the entire tooling structure more compact, and at the same time making the force exerted by the lifting member 2 when lifting and pushing the pull plate 3 return to the base 1, forming a force closed loop, without the need to rely on other external force-bearing components.

[0040] In the specific implementation, it also includes a push plate 5; the push plate 5 is installed on the jacking end; push rods are respectively provided on both sides of the push plate 5 and connected to the pull plate 3; through the switching effect of the push plate 5, the jacking movement of the single point of the jacking end of the jacking member 2 can be converted into a pushing effect on both sides of the pull plate 3.

[0041] In a specific implementation, first through holes corresponding to the positions of the push rods are respectively provided on both sides of the clamping plate 4; the push rods are slidably connected to the first through holes, which can make the entire structure more compact and save space.

[0042] In a specific implementation, the jacking member 2 adopts a hydraulic jack and uses existing mature jacking technology, which can save the design and manufacturing cost of the entire tooling.

[0043] In a specific implementation, the first clamping slot 41 and the second clamping slot 31 adopt a U-shaped slot structure, wherein the arc-shaped end is the main stress-bearing part, which can prevent excessive stress concentration.

[0044] In a specific implementation, a reinforcement plate 12 is also included; the reinforcement plate 12 is installed at the top of the plurality of columns 11 to reinforce each column 11, prevent each column 11 from shaking under stress, and increase the stress strength of each column 11.

[0045] In the specific implementation, it also includes an adjustment plate 6; the adjustment plate 6 is installed on the upper surface of the pull plate 3; a third card slot is provided on the adjustment plate 6; the position of the third card slot corresponds to the second card slot 31, and the adjustment plate 6 is used as the force-bearing part that directly contacts the bearing transmission mechanism 7. When wear occurs, it can be easily replaced to ensure the service life of the entire tooling.

[0046] In a specific implementation, the diameter of the third slot is smaller than that of the second slot 31 , or is the same as the diameter of the second slot 31 , so that the tooling can be applicable to bearing transmission mechanisms 7 of various sizes.

[0047] In a specific implementation, the device also includes an alarm device mounted on the pull plate 3. The alarm device includes a sensor, a controller, a display light or speaker, and a battery. The controller is connected to the sensor, display light or speaker, and battery, respectively. The sensor is a chip resistor, which is affixed to the pull plate 3. Furthermore, the controller can be implemented using a single-chip microcomputer (MCU), which is programmed to have a series of functions such as data acquisition, calculation, and control. In addition to MCUs, other chips or control devices with similar functions can also be used. The chip resistor converts the deformation of the pull plate 3 into an electrical signal and transmits it to the MCU. The MCU calculates the deformation of the pull plate 3 and compares it with a programmed value. If the deformation exceeds the set value, the MCU controls the display light to illuminate red or the speaker to sound a warning tone, alerting personnel that the force on the pull plate 3 exceeds the specified value and that a larger disassembly tool is required.

[0048] Next, the working principle of this embodiment is described in detail to enable those skilled in the art to better understand the present invention:

[0049] Place the lower end and upper end of the bearing transmission mechanism 7 into the slots of the clamping plate 4 and the pull plate 3 respectively at the same time, and at the same time, the clamping position 72 of the lower end of the bearing transmission mechanism is located below the clamping plate 4, and the clamping position 71 of the upper end of the bearing transmission mechanism is located above the pull plate 3; then press the jack to push the push plate 5 upward, and at the same time, the pull plate 3 also moves away from the clamping plate 4 and moves upward, and then the upper and lower ends of the bearing transmission mechanism 7 can be separated.

[0050] In summary, the present application provides a steering gear bearing transmission mechanism disassembly tool, comprising: a base; a plurality of columns disposed around the base; a clamping plate; the clamping plate being horizontally mounted on the plurality of columns; a first latching slot disposed on the clamping plate for receiving and securing the lower end of the bearing transmission mechanism; a pull plate disposed above the clamping plate; a second latching slot disposed on the pull plate; the second latching slot corresponding to the first latching slot for receiving and securing the upper end of the bearing transmission mechanism; and a lifting member connected to the pull plate to push the pull plate up and down relative to the clamping plate. In the present invention, the clamping plate and the pull plate are provided to respectively secure the two parts of the transmission mechanism to be separated. The lifting member then pushes the pull plate away from the clamping plate, thereby driving the transmission mechanism to separate. In the present invention, as long as there are latching slots on each of the two parts to be separated, the operation can be performed. Conventional mechanical transmission structures often have various raised mounting locations or force-bearing areas, making the present invention highly applicable.
