Description
Technical Field
[0001] The invention discloses a steering system for a large passenger bus, belonging to the technical field of large passenger buses. Background Art
[0002] The steering system is a series of devices used to change or maintain the direction of the car's travel or reverse. When turning, the driver turns the steering wheel to make the steering wheels on both sides turn the same angle at the same time to change the direction of the car. When the steering system fails, the car body will shake during driving, or even fail to turn according to the driver's wishes, posing a major safety hazard. Therefore, the steering system is an important guarantee to ensure the safety of the car.
[0003] At present, in terms of the working status of the vehicle steering system, in most cases, the driver actively monitors the steering after discovering an abnormality during driving, and vehicles on the road are generally not equipped with devices for actively monitoring the steering system. In the prior art, there are also some technical solutions for monitoring the vehicle steering system, such as the technical solution disclosed by the Chinese utility model patent with application number: 202122067463.8, application date: August 30, 2021, and patent name: "A vehicle steering angle monitoring device"; the technical solution disclosed by the Chinese invention patent with application number: 202210905864.2, application date: July 29, 2022, and patent name: "A vehicle steering gear monitoring device"; and the technical solution disclosed by the Chinese invention patent with application number: 202210143486.9, application date: February 16, 2022, and patent name: "Vehicle steering system aging monitoring method, device and vehicle".
[0004] However, the existing technologies including the above technical solutions generally target the steering systems of small family vehicles. For large passenger vehicles (referring to passenger vehicles with a length of more than 6 meters and more than 19 seats), take buses as an example: the position of the driving position and the steering wheel in the bus relative to the body is completely different from the relative position of the driving position and the steering wheel in a small vehicle. Therefore, the structure of the central steering system of a large passenger vehicle is different from that of a small family vehicle. Therefore, the existing technical solutions are difficult to directly apply to the monitoring of the steering system of a large passenger vehicle. Therefore, designing a steering system that is convenient for monitoring large passenger vehicles in order to eliminate safety hazards in a timely manner has become a problem that needs to be solved in this field.

DETAILED DESCRIPTION
[0028] Figures 1 to 7 It is the best embodiment of the utility model, and the following Figures 1 to 9 The utility model is further described.
[0029] Embodiment 1:
[0030] like Figures 1 to 4 As shown, a steering system of a large passenger car (hereinafter referred to as the steering system) includes a steering wheel 1, a steering column 2 is coaxially fixed to the lower part of the steering wheel 1, and the bottom of the steering column 2 is connected to one end of a universal joint 3.
[0031] The transmission direction is changed by the universal joint 3, and a steering gear 5 is arranged at the rear side of the universal joint 3, and the other end of the universal joint 3 is connected to the input end of the steering gear 5 through the steering transmission shaft 4. A straight pull rod 6 is connected to the output shaft of the steering gear 5, and the straight pull rod 6 extends backward to the front axle 11.
[0032] A steering shaft mechanism 8 is provided at both ends of the front axle 11, and a wheel hub fixing plate 7 is provided outside the steering shaft mechanisms 8 on both sides, and the wheel hubs of the steering wheels on both sides are fixed by the wheel hub fixing plates 7 on both sides. The straight tie rod 6 extends to the front axle 11 and is connected to the steering shaft mechanism 8 on one side.
[0033] Steering arms 9 are respectively arranged at the rear sides of the steering shaft mechanisms 8 on both sides, and a steering tie rod 10 is arranged between the steering arms 9 on both sides. The two ends of the steering tie rod 10 are respectively hinged to the ends of the steering arms 9 on both sides. When the driver turns the steering wheel 1 in the driving position, the rotation angle of the steering wheel 1 is transmitted to the steering gear 5 through the steering column 2 and the universal joint 3. The steering gear 5 drives the steering shaft mechanism 8 on one side to rotate through the straight tie rod 6, and the steering shaft mechanism 8 connected to the straight tie rod 6 drives the steering shaft mechanism 8 on the other side to rotate at the same angle through the steering tie rod 10. During actual driving, the steering wheels on both sides rotate at the same time.
[0034] Combination Figure 5A shield 22 is provided at the lower part of the steering wheel 1. The rotation axis of the steering wheel 1 passes through the shield 22 and is connected to the steering column 2. The steering wheel 1 and the shield 22 rotate relative to each other. A front sensing plate 12 is fixed at the center of the lower surface of the steering wheel 1. The front sensing plate 12 rotates synchronously with the steering wheel 1. A front Hall angle sensor 13 is fixed on the surface of the shield 22. The front Hall angle sensor 13 cooperates with the front sensing plate 12, and the rotation angle of the steering wheel 1 is monitored through the front Hall angle sensor 13.
[0035] Further integration Figures 6 and 7 The steering shaft mechanisms 8 on both sides include a steering shaft 17 and a steering shaft sleeve 16 sleeved on the outside of the steering shaft 17 . The steering shaft 17 is fixed to the end of the front axle 11 . The above-mentioned steering arm 9 and the wheel hub fixing plate 7 are fixed to the steering shaft sleeve 16 .
[0036] A rear sensing plate 15 is provided at the lower part of the steering shaft sleeve 16, and the rear sensing plate 15 is fixed to the steering shaft sleeve 16 through the first fixing agent 14 and the second fixing frame 18 at both ends thereof. A rear Hall angle sensor 19 is fixed to the side of the steering shaft 17, and the rotation angles of the steering shaft sleeves 16 on both sides are monitored respectively by the rear Hall angle sensors 19 on both sides.
[0037] The signal output ends of the front Hall angle sensor 13 and the rear Hall angle sensor 19 are connected to a controller, which can be implemented by a controller that comes with the bus or by a controller that is added later. At the same time, the front Hall angle sensor 13 and the rear Hall angle sensor 19 can also be installed before the bus leaves the factory, or can be installed later during maintenance. The output end of the controller is connected to an alarm, which can be directly connected to the bus and set on the driving instrument. The alarm can be implemented by a common sound and light alarm method in this field.
[0038] The specific working process and working principle are as follows:
[0039] When the driver turns the steering wheel 1 in the driving position, the rotation angle of the steering wheel 1 is transmitted to the steering gear 5 through the steering column 2 and the universal joint 3. The steering gear 5 drives the steering shaft mechanism 8 on one side to rotate through the straight tie rod 6, and the steering shaft mechanism 8 connected to the straight tie rod 6 drives the steering shaft mechanism 8 on the other side to rotate at the same angle through the steering tie rod 10. During actual driving, the steering wheels on both sides rotate at the same time.
[0040] During driving, the front Hall angle sensor 13 monitors the rotation angle of the steering wheel 1, and the rear Hall angle sensors 19 on both sides monitor the rotation angle of the steering shaft mechanisms 8 on both sides (i.e., the rotation angle of the steering wheel). By monitoring the steering wheel 1 and the steering wheel rotation angle, it can be determined whether the proportional relationship between the steering wheel rotation angle and the steering wheel 1 is normal, and whether the rotation angles of the steering wheels on both sides are consistent, thereby realizing the judgment of the working state of the bus steering system. When the steering system is found to be working abnormally, an alarm is sounded through the alarm.
[0041] Embodiment 2:
[0042] The difference between this embodiment and embodiment 1 is that in this embodiment, other methods are used to monitor the steering wheel 1 and the steering angle. In this embodiment, the steering wheel 1 and the steering angle are monitored by a common grating sensor in the art.
[0043] like Figures 8 and 9 As shown, the rear sensing plate 15 arranged at the steering shaft sleeves 16 on both sides is replaced with a grating plate 20, and the rear Hall angle sensor 19 fixed on the side of the steering shaft 17 is replaced with a grating sensor 21. At the same time, the front sensing plate 12 and the front Hall angle sensor 13 at the steering wheel 1 are replaced accordingly.
