Description

Technical Field

[0001] The utility model relates to a braking system for a sightseeing tractor, belonging to the technical field of sightseeing vehicles. Background Art

[0002] Sightseeing cars generally use batteries to generate power, which is environmentally friendly and pollution-free, and effectively utilizes resources. They have personalized control systems, flexible steering, comfortable feel, light and smooth, easy to drive, electric and recyclable, and long life.

[0003] Usually, the high and low speed braking of sightseeing tractors is completed by stepping on the brake pedal. The subtle speed of vehicle braking acceleration, coupled with the driver's reaction and the inertia of stepping on the brake pedal, prolongs the deceleration operation time, which can easily increase the speed and overspeed, causing great safety hazards. It is impossible to intelligently control the loosening of the brake pedal to decelerate. Therefore, a braking system for sightseeing tractors is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a sightseeing tractor braking system in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a braking system for a sightseeing tractor, comprising a brake pedal, a first brake link, a second brake link, a U-shaped member, a first rotating shaft, a U-shaped plate, an integrated cylinder, a second rotating shaft, a manual valve, an electric control valve, a controller and a speed sensor, wherein one end of the first brake link located on the back of the brake pedal is rotatably connected to a corresponding portion on the inner side of one end of the second brake link through a second rotating shaft, and slots are distributed on both side walls of one end of the first brake link, and the slots are inserted into the corresponding push rod ends in the integrated cylinder, and the integrated cylinder is fixedly connected to the corresponding portion of one end of the second brake link through the U-shaped plate, the integrated cylinder is connected to a port corresponding to the electric control valve through a pipe body, and the electric control valve is electrically connected to the controller through a signal line.

[0006] Preferably, two integrated cylinders are provided, and the two integrated cylinders are respectively fixedly mounted on both sides of the same U-shaped plate.

[0007] Preferably, both ends of the second rotating shaft are provided with torsion springs.

[0008] Preferably, one side of the middle portion of the second brake link is rotatably connected to the two ends of the U-shaped member through a first rotating shaft.

[0009] Preferably, the input end of the controller is electrically connected to the speed sensor.

[0010] Preferably, a manual valve is installed on the tube body between the integrated cylinder and the electric control valve.

[0011] The beneficial effect of the utility model is that: the second brake link uses the second rotating shaft at the end of the first brake link as the lateral rotation fulcrum, so that the end of the second brake link with an integrated cylinder is turned upward, and at the same time, it is partially separated and moved from the first brake link and the brake pedal and is in a linkage state of low speed control braking again, with the function of emergency speed reduction braking, which solves the problem of overspeeding due to the driver's continuous inertia of stepping on the brake pedal, and at the same time ensures that the vehicle is in a safe low-speed running state, thereby improving the safety performance of the sightseeing car's braking driving.

[0017] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0020] See also Figure 1-3 As shown, a sightseeing tractor braking system includes a brake pedal 1, a first brake link 2, a second brake link 3, a U-shaped member 4, a first rotating shaft 5, a U-shaped plate 6, an integrated cylinder 7, a second rotating shaft 8, a manual valve 9, an electric control valve 10, a controller 11 and a speed sensor 12. One end of the first brake link 2 located on the back of the brake pedal 1 is rotatably connected to the corresponding part on the inner side of one end of the second brake link 3 through the second rotating shaft 8, and slots 201 are distributed on both side walls of one end of the first brake link 2.

[0022] When the utility model is in use, the driver steps on the brake pedal 1 to drive the oil valve connected by the first brake link 2 and the second brake link 3 to supply oil. When the speed sensor 12 detects that the vehicle speed exceeds the set speed, the speed sensor 12 transmits the overspeed signal to the controller 11. The controller 11 issues an opening and closing command to the electric control valve 10, the integrated cylinder 7 is exhausted and the output end is contracted and separated from the slot 201.
