Description

Technical Field

[0001] This utility model relates to the field of drive-by-wire automotive steering gear technology, and in particular to a drive-by-wire automotive steering gear that is easy to manufacture. Background Technology

[0002] A steer-by-wire system is a technology and device that uses an electronic system to assist vehicle steering. Traditional hydraulic power steering systems use hydraulic pumps and hydraulic boosters to provide steering assistance, while steer-by-wire systems use electric motors and sensors to achieve steering assistance. The steer-by-wire gear is a key component in the steer-by-wire system. Its function is to transmit steering driving force to other components of the steering system, such as the steering column and steering gear. It is responsible for converting the power output of the electric motor into steering force, thereby helping the driver to operate the vehicle more easily.

[0003] In addition to transmitting steering force, the steer-by-wire gear also plays a safety protection role in the steering system. It can monitor the status of the steering system through sensors, and automatically issue an alarm or take measures when the system malfunctions or fails, so as to ensure driving safety. However, most steer-by-wire gears in the existing technology are one-piece designs, with the sensors directly installed in the rivet holes on the steering gear. This requires high processing technology and increases the complexity of processing. Therefore, it is necessary to design a steer-by-wire gear that is easy to process to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a steer-by-wire gear that is easy to manufacture.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A steerable drive-by-wire gear for automobiles, facilitating machining, includes a toothed section. A large bearing stop is fixedly connected to one side of the toothed section. A maximum outer diameter stop is fixedly connected to the large bearing stop on the side away from the toothed section. A sensor stop is fixedly connected to the maximum outer diameter stop on the side away from the large bearing stop. The sensor stop has two straight grooves, an oblique groove, and a first square groove. A sleeve is fitted onto the sensor stop. Two second square grooves are formed on the inner wall of the sleeve. Two guide rods are disposed within the second square grooves, and the guide rods are fixedly connected to the sleeve. Two sliding plates are disposed within the second square grooves, and the sliding plates are fitted onto the two guide rods, slidably connecting the guide rods. Two springs are disposed between the two sliding plates, and the springs are fitted onto the guide rods. Due to the modular design, the steering gear and... The technology of independently machining the sleeve for mounting the sensor allows each module to be processed independently. Furthermore, the sleeve is secured by a sliding plate, ensuring stable mounting on the sensor mount. This facilitates easier assembly and replacement of gears with other components. This effectively solves the problem mentioned in the background section where most existing steerable drive systems use a single-piece design with the sensor directly mounted in a rivet hole, requiring advanced machining processes and increasing complexity. Modular design simplifies machining, improves overall processing efficiency, and shortens the manufacturing cycle. It also simplifies maintenance and component replacement, allowing for quick replacement of damaged modules without replacing the entire steering system, thus reducing maintenance costs and time.

[0007] As a further embodiment of this utility model, the outer wall of the sleeve is provided with eight slots, and the slots are connected to the second square groove.

[0008] As a further embodiment of this utility model, both sliding plates have inclined surfaces at their ends on opposite sides.

[0009] As a further embodiment of this utility model, the sensor block is fixedly connected to an input end on the side away from the teeth, and the input end is provided with a pin hole.

[0010] As a further embodiment of this utility model, the outer wall of the sleeve is provided with a plurality of sensor rivet holes.

[0011] As a further embodiment of this utility model, a tooth positioning hole is provided on the tooth portion.

[0012] As a further embodiment of this utility model, a small bearing stop is fixedly connected to the tooth on the side away from the large bearing stop, and a threaded stop is fixedly connected to the small bearing stop on the side away from the tooth.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model utilizes a modular design, where the steering gear and the sensor mounting sleeve are processed independently. This allows for independent machining of each module, and the sensor mounting sleeve is secured by a sliding plate, ensuring stable installation on the sensor mount. This facilitates easier assembly and replacement of the gear with other components. It effectively solves the problem presented in the background art where most existing steerable drive systems use a single-piece design with sensors directly mounted in rivet holes, requiring advanced machining processes and increasing complexity.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and implementing regulations.

[0022] Reference Figure 1 - Figure 4 A drive-by-wire automotive steering gear that is easy to manufacture includes a tooth portion 101. A large bearing stop 102 is fixedly connected to one side of the tooth portion 101. A maximum outer diameter stop 103 is fixedly connected to the large bearing stop 102 on the side away from the tooth portion 101. A sensor stop 104 is fixedly connected to the maximum outer diameter stop 103 on the side away from the large bearing stop 102. The sensor stop 104 has two straight grooves 105, a slanted groove 106, and a first square groove 107. A sleeve 2 is fitted onto the sensor stop 104. Two second square grooves 201 are formed on the inner wall of the sleeve 2. Two guide rods 3 are arranged in the second square grooves 201. The guide rods 3 are fixedly connected to the sleeve 2. Two sliding plates 5 are arranged in the second square grooves 201. The sliding plates 5 are fitted onto the two guide rods 3. The movement of the sliding plates 5 will move along the guide rods 3 to ensure the stability of the sliding plates 5 during movement. The sliding plates 5 are slidably connected to the guide rods 3. Two springs 4 are arranged between the two sliding plates 5. The springs 4 are extended. The two sliding plates 5 can be locked in the first square groove 107, and the spring 4 is sleeved on the guide rod 3. Due to the modular design, the steering gear and the sleeve for mounting the sensor are processed independently. Therefore, each module can be processed independently, and the sleeve for mounting the sensor is limited by the sliding plate so that the sleeve can be stably installed on the sensor. This makes it easier to assemble and replace the gear with other components. This effectively solves the problem mentioned in the background art that most of the existing drive-by-wire steering gears are designed as one piece, and the sensor is directly installed in the rivet hole on the steering gear, which has high requirements for the processing technology and increases the complexity of processing. In this way, the modular design is realized to facilitate processing, improve the overall processing efficiency, shorten the manufacturing cycle, and make maintenance and replacement of parts simpler. Damaged modules can be quickly replaced without replacing the entire steering system, which reduces maintenance costs and time.

[0023] In this embodiment, the outer wall of the sleeve 2 is provided with eight slots 6. When the sleeve 2 needs to be removed, a rod-shaped object that can be inserted into the slot 6 is used to press the sliding plate 5 so that the two sliding plates 5 are close to each other and adapt to the width of the straight groove 105. The slot 6 is connected to the second square groove 201.

[0024] In this embodiment, both sliding plates 5 have inclined surfaces 7 at their ends on opposite sides, and pressing the inclined surfaces 7 on the sliding plates 5 causes the sliding plates 5 to move.

[0025] In this embodiment, the sensor plate 104 is fixedly connected to an input terminal 8 on the side away from the toothed part 101, and a pin hole 9 is provided on the input terminal 8.

[0026] In this embodiment, the outer wall of the sleeve 2 is provided with a plurality of sensor rivet holes 10.

[0027] In this embodiment, a tooth positioning hole 1011 is provided on the tooth 101, which is used to position the angle between the tooth 101 and the input end 8.

[0028] In this embodiment, a small bearing stop 108 is fixedly connected to the toothed part 101 on the side away from the large bearing stop 102, and a threaded stop 109 is fixedly connected to the small bearing stop 108 on the side away from the toothed part 101. The threaded stop 109 is connected and fixed to other components of the steering gear. The threaded connection can withstand dynamic loads, prevent loosening, and ensure the overall stability and safety of the structure.

[0029] Working principle: The sensor is installed in the sensor rivet hole 10. The threaded stop 109 is connected and fixed to other components of the steering gear (such as the motor, transmission device, etc.) to ensure the overall stability and safety of the structure. A good threaded connection can withstand dynamic loads and prevent loosening. Using the threaded stop 109 makes the assembly and disassembly of various components more convenient. When maintaining or replacing components, the threaded connected components can be quickly disassembled, saving time and effort. The threaded stop provides physical positioning to ensure that each component is in the correct position during assembly, avoiding failures caused by positional deviations and facilitating processing. A pin is used to connect to the steering gear through the pin hole 9. The sleeve 2 is placed on the sensor stop 104. Then, the sleeve 2 is moved, which drives the guide rod 3 to move. The guide rod 3 drives the sliding plate 5 to move. The sliding plate 5 enters the inclined groove 106. Moving the sleeve 2 makes the sliding plate... As the sleeve 2 moves within the inclined groove 106, the two sliding plates 5 will move closer to each other, and the sliding plates 5 will also cause the spring 4 to contract. When the sliding plate 5 moves into the straight groove 105, the spring 4 will fully contract, and the sleeve 2 will extend until the sliding plate 5 moves into the first square groove 107, so that the two sliding plates 5 move away from each other and are locked into the first square groove 107, thus ensuring the stability of the sleeve 2. The sleeve 2 adopts a modular design, and the sleeve 2 and the steering gear are processed independently, which improves the overall processing efficiency and facilitates on-site assembly and processing. When the sleeve 2 needs to be removed to maintain the sensor in the sensor rivet hole 10, a rigid rod that can be inserted into the slot 6 is used. The rod is inserted into the slot 6 to squeeze the sliding plate 5. The rod will move along the inclined surface 7, so that the two sliding plates 5 move closer to each other until they can adapt to the width of the straight groove 105, so that the sleeve 2 moves away from the tooth 101 and the sleeve 2 can be removed.
