Description
Technical Field
The utility model relates to an automobile steering technical field, concretely relates to four-wheel steering system of baha cycle racing.
Background
"Baja SAE China (BSC) is a race for designing, manufacturing and testing off-road vehicles, which are participated in by the colleges and universities, vocational colleges and related professionals in the school and students. The racing motorcade uses the same type of engine to design and manufacture a single-seat, mid-engine and rear-drive small off-road vehicle or a four-drive small off-road vehicle at the set time according to the racing rules and the racing car manufacturing standards.
In the case of a four-wheel drive scheme, if steering is performed only by the front wheels, the steering radius may be too large to reduce the maneuverability of the vehicle due to the limitation of the tire rotation angle by the cage. Secondly, the four-wheel steering system of mechanical control needs a steering transmission shaft that runs through the automobile body, has increased the car weight, and the steering control power is great under the condition of not having the helping hand, has increased the control degree of difficulty, has crowded simultaneously and has taken up passenger's space, has increased the overall arrangement complexity of car.
SUMMERY OF THE UTILITY MODEL
The utility model mainly aims to provide a four-wheel steering system of baha cycle racing to solve the problem that prior art exists.
In order to solve the technical problem, the utility model discloses following technical scheme has been taken:
the four-wheel steering system of the Baha racing car comprises a front steering machine and a rear steering machine, wherein a sensor is arranged at the bottom of the front steering machine and used for detecting a steering angle, a steering engine is arranged at the top of the rear steering machine, a main controller is arranged on the steering engine, and the main controller is connected with the sensor through a lead.
Further, the sensor is a magnetic induction angular displacement sensor.
Furthermore, the main controller is installed on the steering engine through a switching seat.
Furthermore, the steering wheel and the steering column are further included, and the steering wheel is connected with the front steering engine through the steering column.
Furthermore, the steering mechanism further comprises a steering pull rod and a steering knuckle arm, wherein the steering pull rod is arranged on two sides of the front steering engine and the rear steering engine, and the steering knuckle arm is arranged between the steering pull rod and the tire.
Compared with the prior art, the utility model discloses following beneficial effect has:
compared with the traditional mechanical four-wheel steering, the utility model directly transmits the steering information to the main controller of the rear steering machine in the form of electric signals through the sensor positioned on the front steering machine, when the steering angle of the front wheel is small, the steering engine of the rear wheel drives the rear wheel to turn in the same direction, so that the control stability of the racing car can be improved, and the racing car is suitable for high-speed small-angle steering; when the front wheel has a larger corner, the rear steering machine can drive the rear wheel to reversely turn, so that the turning radius is reduced, the rear steering machine is suitable for low-speed large-angle steering, the precision is improved while the weight is reduced, and the steering burden of a driver is reduced.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a schematic structural view of the front steering gear of the present invention.
Fig. 3 is a schematic structural view of the rear steering gear of the present invention.
The steering system comprises a front steering engine 1, a sensor 11, a steering gear 12, a rear steering engine 2, a steering engine 21, a main controller 22, an adapter 23, a steering wheel 3, a steering column 4, a steering pull rod 5 and a steering knuckle arm 6.
Detailed Description
The technical solution of the present invention is further explained by the accompanying drawings and examples.
Combine fig. 1 to fig. 3, the utility model provides a four-wheel steering system of baha cycle racing, turn to quick-witted 2 after with including preceding steering wheel 1, preceding steering wheel 1 bottom is equipped with sensor 11, sensor 11 is used for detecting and turns to the angle, 2 tops of rear steering wheel are equipped with steering wheel 21, turn to and be equipped with main control unit 22 on the steering wheel 21, main control unit 22 with sensor 11 passes through the wire and connects, main control unit 22 through adapter 23 install in turn to on the steering wheel 21.
In this embodiment, the sensor 11 is a magnetic induction angular displacement sensor, the angular displacement sensor is connected to the main controller 22 through a wire, and transmits a steering angle signal to the main controller 22, and the specific position of the sensor 11 is located at the lower part of the steering gear of the front steering gear 1.
Preferably, the steering wheel device further comprises a steering wheel 3, a steering column 4, a steering pull rod 5 and a steering knuckle arm 6, wherein the steering wheel 3 is connected with the front steering engine 1 through the steering column 4, the steering pull rod 5 is arranged on two sides of the front steering engine 1 and the rear steering engine 2, and the steering knuckle arm 6 is arranged between the steering pull rod 5 and a tire.
In this embodiment, the main controller 22 is provided with a turning angle threshold, when the turning angle of the steering wheel 3 with a high vehicle speed is smaller than the set threshold, the main controller 22 does not issue a equidirectional turning instruction after receiving the signal sent by the sensor 11, the rear steering gear 2 drives the rear wheel to turn with the front wheel in the same direction, after the turning angle of the steering wheel 3 with a low vehicle speed exceeds the set threshold, the main controller 22 receives the signal sent by the processing sensor 11 and issues a working instruction, and the rear steering gear 2 drives the rear wheel to turn reversely, thereby reducing the turning radius.
The working principle is as follows: when the automobile steering device works, the steering wheel 3 drives a steering gear of the front steering engine 1 to rotate through the steering column 4, a steering angle signal is further transmitted to the sensor 11, the sensor 11 transmits the signal to the main controller 22, when the angle of the steering wheel 3 rotated by a driver at a high automobile speed is small, the signal received by the sensor 11 fails to reach a preset threshold value, at the moment, the main controller 22 sends an operation instruction, and the steering engine 21 pushes the rear wheels to turn in the same direction; when the vehicle speed is low and the angle of the steering wheel 3 rotated by a driver is large, the signal received by the sensor 11 reaches a preset threshold value, the main controller 22 sends an operation instruction, and the steering engine 21 starts to work to control the rear steering engine 2 to drive the rear wheels to steer in the direction opposite to the direction of the front wheels, so as to obtain a smaller turning radius.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modification, equivalent change and modification made to the above embodiments by the technical essence of the present invention are all within the scope of the technical solution of the present invention.
