Abstract
The utility model relates to a brake shoe abrasion monitoring switch, which has a structure that a through hole is formed on the brake shoe and a friction plate, a thin sheet body is arranged in the through hole, a line-shaped conductor is attached to the thin sheet, and a conducting wire is externally connected with the line-shaped conductor. The brake shoe abrasion monitoring switch not only can monitor the abrasion of the friction plate of the brake shoe, but also can effectively monitor the loosening and the shifting of the friction plate and the brake shoe due to infirm connection as well as the faults such as cutting off, falling off and flying off. The brake shoe abrasion monitoring switch has a simple structure, is convenient to mount and adjust, and has correct, comprehensive and reliable monitoring information.
Description
Technical field
The utility model relates to a kind of abrasion detection sensor, specifically a kind of brake shoe wear monitoring switch.
Background technique
Existing a kind of brake shoe wear monitoring switch comprises a lead, a nonmetal hollow screw and a link arm; One end of link arm is fixed on the brake shoe, and hollow screw is by the vertical wheel limit of putting at Brake drum of link arm, and lead penetrates in the core chamber of hollow screw.Lead did not contact with Brake drum before this in good condition, thereby passed out the signal of " conducting " to control system.Along with the wearing and tearing gradually of the friction plate of brake shoe inboard, the spacing between brake shoe and Brake drum wheel face is dwindled, and the lower end of hollow screw also touches Brake drum gradually, and is is synchronously worn and torn, and the lead in the screw core chamber contacts with Brake drum gradually.When the lead of friction plate continuation wearing and tearing in screw rubbed, brake shoe wear monitoring switch just passes out " disconnection " signal to control system, very serious and can not use again with the wearing and tearing that show the friction plate on the brake shoe, should change brake shoe or friction plate.
The shortcoming that this brake shoe wear monitoring switch exists: the one, can only monitor the wearing and tearing of brake shoe friction plate, and for the loose shift of friction plate or come off, then can not monitor effectively; The 2nd, install and adjust inconvenience, provide error signal easily.
The model utility content
The purpose of this utility model just provides a kind of brake shoe wear monitoring switch, to solve the problem that pilot switch monitoring project is complete, forbidden and install adjustment inconvenience that has now.
The utility model is achieved in that a kind of brake shoe wear monitoring switch, has through hole on brake shoe and friction plate, is provided with the thin slice body in described through hole, is attached with linear conductor on described thin slice body, described linear conductor external wire.
Become U-shaped attached to the described linear conductor on the described thin slice body.
Described thin slice body is a printed circuit board (PCB), and described linear conductor is printed on the described printed circuit board (PCB).
The utility model both can have been monitored the wearing and tearing of brake shoe friction plate, and fault also can effectively be monitored because of being connected the not firm loose shift that occurs even cut off, come off and fly out etc. for friction plate and brake shoe.The utility model is simple in structure, install easy to adjust, monitor message accurately, comprehensively, reliable.
Description of drawings
Fig. 1 structural representation of the present utility model.
Embodiment
As shown in Figure 1, on brake shoe 1 and friction plate 2, have a through hole, in this through hole, fix a thin slice body 3, on thin slice body 3, be attached with the linear conductor 4 of U-shaped, the two ends of linear conductor 4 respectively connect a lead 5, and lead 5 is connected with control system, transmit supervisory signal.
Thin slice body 3 can be very thin circuit board, preferably printed circuit board (PCB); Linear conductor 4 can be the copper lines that is printed on the printed circuit board (PCB), also can adopt other such as mode such as bonding attached on the circuit board.
Working principle of the present utility model is: thin slice body 3 is imbedded in the through hole on brake shoe 1 and the friction plate 2, and external lead 5 is connected with control system.Because linear conductor 4 is communicated with, so this pilot switch sends " conducting " signal to control system always, the abnormal conditions of friction plate simultaneously, do not take place in the wearing and tearing of indication brake shoe still within the range of permission yet.Be braked wheel 6 progressively after the wearing and tearing at friction plate 2, also being worn and torn synchronously in the lower end of thin slice body 3, when the U-shaped of linear conductor 4 bottom is rubbed, promptly sends " disconnection " signal to control system.If becoming flexible, break away from or situation such as the brake shoe that flies out when taking place of friction plate arranged, the thin slice body 3 of this pilot switch is promptly fractureed simultaneously, linear conductor 4 on the thin slice body 3 disconnects thereupon, this pilot switch promptly sends " disconnection " signal to control system, points out the brake shoe serious wear or has the abnormal conditions of friction plate to take place.
Claims (3)
1. brake shoe wear monitoring switch, it is characterized in that, on brake shoe (1) and friction plate (2), have through hole, in described through hole, be provided with thin slice body (3), on described thin slice body (3), be attached with linear conductor (4), described linear conductor (4) external wire (5).
2. brake shoe wear monitoring switch according to claim 1 is characterized in that, becomes U-shaped attached to the described linear conductor (4) on the described thin slice body (3).
3. brake shoe wear monitoring switch according to claim 1 and 2 is characterized in that described thin slice body (3) is a printed circuit board (PCB), and described linear conductor (4) is printed on the described printed circuit board (PCB).
