Description

Technical Field

[0001] This utility model relates to a light truck front axle, specifically an intelligent commercial vehicle light truck front axle. Background Technology

[0002] Driving assistance devices can help drivers improve their senses, perception, judgment, and operational abilities, and can reduce driver workload, improve safety and comfort. Unlike active safety, passive safety cannot prevent or avoid accidents, but can only play a role after an accident has occurred. However, for driving safety, accident prevention is much more important than post-accident protection. Therefore, active safety, which has the function of preventing accidents, will become the first choice in the field of safe driving, especially for commercial vehicles. However, the market currently lacks a front axle that can transmit information such as front axle speed, direction, forward, reverse, and parking to the vehicle controller in real time and cooperate with the vehicle control unit to complete the assisted driving. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide an intelligent front axle for commercial light trucks.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: an intelligent commercial vehicle light truck front axle, including a front axle and a steering knuckle rotatably mounted on the outer end of the front axle. The steering knuckle shaft is supported by a front wheel hub through a bearing unit. A brake disc is fixed at the outer end of the front wheel hub. The steering knuckle is equipped with a brake caliper corresponding to the inner side of the brake disc. Steering knuckle pins are respectively provided at the upper and lower outer ends of the front axle. The upper and lower steering knuckle support sleeves on the inner side of the steering knuckle are respectively fitted onto the corresponding steering knuckle pins. Thrust bearings are respectively provided between the upper and lower steering knuckle support sleeves and the steering knuckle pins. A gear ring is fixed on the inner outer edge of the front wheel hub. An intelligent sensor is fixed on the side of the steering knuckle near the gear ring. The detection end of the intelligent sensor is opposite to the gear ring and forms a sensing gap.

[0005] Furthermore, the intelligent sensor penetrates the mounting plate that fixes the steering knuckle and is fixed to the mounting plate by bolts. The intelligent sensor consists of a Hall effect wheel speed sensor and a rotation angle sensor.

[0006] Furthermore, the inner outer edge of the front wheel hub is provided with an inwardly recessed platform, and the gear ring is interference-fitted onto the platform.

[0007] Furthermore, the detection end of the smart sensor is parallel to the circumference of the gear ring.

[0008] Furthermore, the lower sleeve portion of one side of the steering knuckle is equipped with a tie rod arm and a tie rod that drive the steering knuckle to rotate.

[0009] Furthermore, each steering knuckle has a tie rod arm on its upper sleeve that drives the left and right steering knuckles to rotate synchronously.

[0010] Furthermore, a hub cap is fixed to the outer end of the front wheel hub.

[0011] Through the above design and improvements, when the vehicle is in motion, the wheels drive the front wheel hub to rotate through the wheel hub bolts and nuts. The gear ring installed on the front wheel hub and the intelligent sensor fixed on the steering knuckle form relative motion. The relative motion between the intelligent sensor and the gear ring generates a waveform signal. By identifying different waveform signals, the vehicle controller can automatically identify the actual operating status of the vehicle.

[0012] It is easy to match with 2Xφ56 hydraulic brake calipers, providing high braking force and fast response. The braking force is 21% higher than that of 2Xφ54 brake calipers, significantly reducing braking distance. The fast response and short braking distance meet active safety requirements.

[0013] In addition, the front axle of this utility model is based on road spectrum data collection and has a brand-new positive development of a new cross-section I-beam. Compared with the round tube beam, it is 5% lighter and 26% stronger. Compared with the original 2-ton platform I-beam, it is 20% lighter. The new structure front axle has the advantages of being applicable to both 1.5-ton and 2-ton platforms, being lightweight and having high strength. Attached Figure Description

[0019] Example

[0020] like Figure 1-4As shown, an intelligent commercial vehicle light truck front axle includes a front axle 1 and a steering knuckle 2 rotatably mounted on the outer end of the front axle 1. The main I-beam of the front axle is based on road spectrum data collection, and a new cross-section I-beam has been developed from the ground up. Compared to a round tube beam, it reduces weight by 5% and increases strength by 26%. Compared to the original 2-ton platform I-beam, it reduces weight by 20%. The new structure front axle is applicable to both 1.5-ton and 2-ton platforms, offering advantages of light weight and high strength. The steering knuckle 2's axle is supported by a bearing unit 3 on the outside of the front wheel hub 4. A brake disc 5 is fixed to the outer end of the front wheel hub 4. The steering knuckle 2 is equipped with a brake caliper 6 corresponding to the inner side of the brake disc 5. If matched with a 2Xφ56 hydraulic brake caliper, it provides high braking force and fast response speed. The braking force is 21% higher than that of the traditional 2Xφ54 brake caliper, significantly shortening the braking distance. The fast response speed and short braking distance meet active safety requirements. The outer end of the front axle 1 is respectively equipped with... Steering knuckle pin 7, upper and lower steering knuckle support sleeves 8 on the inner side of steering knuckle 2 respectively fit onto the corresponding steering knuckle pin 7, and thrust bearings 9 are respectively provided between the upper and lower steering knuckle support sleeves 8 and steering knuckle pin 7. A gear ring 10 is fixed on the inner outer edge of the front wheel hub 4. A smart sensor 11 is fixed on the side of steering knuckle 2 near the gear ring 10. The smart sensor 11 consists of a Hall wheel speed sensor and a rotation angle sensor. The detection end of the smart sensor 11 is opposite to the gear ring 10 and forms a sensing gap. This is conducive to the smart sensor 11 generating a specific waveform signal. That is, by matching the Hall wheel speed sensor and the rotation angle sensor to replace the current ordinary magnetoelectric sensor, the speed, forward, reverse, parking and other information are determined by the specific waveform signal. The rotation angle sensor monitors the vehicle rotation direction and rotation angle in real time and transmits the relevant information to the vehicle controller, thereby achieving intelligent connection with the whole vehicle.

[0021] Specifically: The intelligent sensor 11 passes through the mounting plate 12 fixed to the steering knuckle 2, and the intelligent sensor 11 is fixed to the mounting plate 12 by bolts. The inner outer edge of the front wheel hub 4 is provided with an inwardly recessed platform 13. The gear ring 10 is interference-fitted onto the platform 13, and the detection end of the intelligent sensor 11 is parallel to the circumferential surface of the gear ring 10.

[0022] In addition, the existing technology also includes: a tie rod arm 14 and a tie rod 15 that drive the steering knuckle 2 to rotate on the lower sleeve part of one side; a straight tie rod arm 16 that drives the left and right steering knuckles 2 to rotate synchronously on the upper sleeve part of each side of the steering knuckle 2; and a hub cap 17 that is fixed to the outer end of the front wheel hub 4.

[0023] The working principle of this utility model is the same as that of the existing automotive front axle. For example, the front axle brake caliper 6 is directly installed on the steering knuckle 2. When the vehicle is braking, the oil supply line of the whole vehicle injects oil into the cylinder of the brake caliper 6 and pressurizes it. The friction block of the brake caliper 6 presses the brake disc 5 and generates friction torque. This torque is transmitted to the wheel through the front wheel hub 4 and the wheel hub bolts and nuts, causing the whole vehicle to decelerate. The greater the braking force, the greater the deceleration of the vehicle, thus forming the whole vehicle braking process.

[0024] In addition, when the vehicle is in motion, the wheels drive the front wheel hub 4 to rotate via the wheel hub bolts and nuts. The gear ring 10 mounted on the front wheel hub and the intelligent sensor 1 fixed on the steering knuckle form relative motion. The relative motion between the intelligent sensor 11 and the gear ring 10 generates waveform signals. By recognizing the following waveform signals, the vehicle controller can automatically identify the actual operating status of the vehicle, such as... Figure 4 As shown.

[0025] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
