Abstract
The utility model discloses a motor vehicle arresting gear, including braking master cylinder (2), brake handle (1) and oil cup (3), oil cup (3) with braking master cylinder (2) intercommunication, its characterized in that be provided with float (4) in oil cup (3), be provided with magnet (5) on float (4) the bottom of oil cup (3) set up with magnetic force inductive switch (8) that magnet (5) correspond. The utility model discloses a this kind of structure, when the brake fluid in the oil cup reduces, the float can descend promptly, when the float falls the minimum setting value of brake fluid level, can respond to magnetic force inductive switch promptly, and magnetic force inductive switch just can make the pilot lamp of installing on the motor vehicle instrument board light, reminds navigating mate in time to annotate the brake fluid, also guarantees motor vehicle driving safety. The brake device is simple in structure, scientific and reasonable, and brings reliable guarantee for the braking of the motor vehicle.
Description
Technical Field
The utility model relates to a motor vehicle arresting gear especially involves the arresting gear of motorcycle.
Background
The braking of the motorcycle generally adopts a hydraulic disc braking system, which comprises a main braking cylinder, an oil cup, a connecting pipeline and braking calipers, and a braking mechanism, such as a hand brake or a foot brake, drives the main braking cylinder to transmit hydraulic oil in the oil cup to each braking caliper for braking through the connecting pipeline. Therefore, in order to monitor the amount of the brake fluid in the oil cup in time, a person skilled in the art often sets an oil mirror on the oil cup, that is, a transparent place is set to observe the condition of the brake fluid in the oil cup. The oil cup with the structure needs to be made of transparent materials, and higher requirements are put on the materials. The oil cup is exposed in the air, so that the surface of the oil cup is adhered by dust after long-term running, and the brake fluid amount in the oil cup is often not visible, so that the brake device still has potential safety hazards.
Disclosure of Invention
In view of the problem that the background art exists, the to-be-solved technical problem of the utility model is to provide a simple structure, can in time monitor the motor vehicle arresting gear of interior brake fluid volume of oil cup.
Therefore, the utility model discloses an adopt following technical scheme to realize: a motor vehicle braking device comprises a braking main oil cylinder, a braking handle and an oil cup, wherein the oil cup is communicated with the braking main oil cylinder.
The inner wall of the oil cup is provided with a guide post, the floater is provided with a limit groove, the guide post is positioned in the limit groove, and the magnetic induction switch is positioned below the magnet.
The float is provided with a positioning groove, the magnet is provided with a flange corresponding to the positioning groove, and the magnet is embedded in the positioning groove through the flange.
The magnetic force inductive switch is provided with a reed switch, and the reed switch is in a normally open state.
The utility model discloses a this kind of structure, when the oil cup internal braking liquid volume reduces, the float descends, and magnet on the float is used for responding to magnetic force inductive switch, and magnetic force inductive switch makes the pilot lamp of installing on the motor vehicle panel board light promptly, is used for reminding the driver in time to annotate the brake liquid to guarantee driving safety, its simple structure, scientific and reasonable has solved not enough in the background art, makes the braking of motor vehicle keep the safe state.
Drawings
The utility model discloses there is following figure:
FIG. 1 is a block diagram of the present invention;
FIG. 2 is a structural diagram of the utility model with magnets embedded on the floats;
fig. 3 is a structural diagram of the magnetic force inductive switch of the present invention.
Detailed Description
Referring to the attached drawings, the motor vehicle braking device comprises a braking main oil cylinder 2, a braking handle 1 and an oil cup 3, wherein the oil cup 3 is communicated with the braking main oil cylinder 2, when the braking main oil cylinder is used on a motorcycle, the braking handle 1 can be a hand braking handle or a foot braking handle, a floater 4 is arranged in the oil cup 3, a magnet 5 is arranged on the floater 4, and a magnetic induction switch 8 corresponding to the magnet 5 is arranged at the bottom of the oil cup 3. When the brake fluid is reduced, the floater 4 descends, and the magnet 5 on the floater 4 is used for sensing the magnetic force sensing switch 8; the inner wall of the oil cup 3 is provided with a guide post 6, the floater 4 is provided with a limit groove 7, the guide post 6 is positioned in the limit groove 7, and the magnetic induction switch 8 is positioned below the magnet 5. The structure enables the magnet 5 on the floater 4 to vertically descend along the guide post 6, the floater 4 cannot deviate, the brake fluid amount in the oil cup 3 is accurately sensed, and a driver can fill brake fluid in time. The float 4 is provided with a positioning groove 9, the magnet 5 is provided with a flange 10 corresponding to the positioning groove 9, and the magnet 5 is embedded in the positioning groove 9 through the flange 10. During assembly, the magnet 5 is only required to be pressed into the positioning groove 9, so that the float structure is very convenient to assemble. The magnetic induction switch 8 is provided with a reed switch 11, and the reed switch 11 is in a normally open state. An indicator light is mounted on the dashboard of the motor vehicle and is electrically connected to the reed switch 11. Since the reed switch 11 is normally open, the indicator lamp is normally off when the brake fluid in the oil cup 3 is in a normal amount. When the brake fluid in the oil cup 3 is gradually reduced in the long-term use process, the floater 4 is reduced to a certain amount along with the descending, the magnetic field of the magnet 5 on the floater 4 enables the two magnetic spring pieces to be in contact, so that the two spring pieces 12 in the reed pipe 11 are in a connected state, therefore, an indicator lamp on an instrument panel can be lightened, a driver can be reminded immediately, and the brake fluid is filled in the process, so that the brake is normal in the driving process, and the driving safety is ensured.
