Description
Technical field:
The utility model battery-driven car servant brake relates to the brake plate sleeve that is installed at the outer hole with lock of battery-driven car servant brake brake disc with hole with lock brake plate sleeve.
Background technology:
Now, on the battery-driven car servant brake, often add lockset, the lock core of lockset promotes locking bar, can insert it in the brake plate sleeve lockhole outside brake disc, reaches the purpose of locking battery-driven car servant brake, when unblanking, then make locking bar withdraw from the lockhole of brake plate sleeve, realize unblanking, therefore, structure for the latch arm hole of the structure of brake plate sleeve, particularly brake plate sleeve should be done special design.
Summary of the invention:
The purpose of this utility model provides a kind of battery-driven car servant brake with being with the latch arm hole brake plate sleeve, it is the annular arrangement cover that suit is welded on the outer brake plate sleeve of brake disc, have some lockholes on the brake plate sleeve body, lockhole is made up of outer circle cambered surface, sidewall rectangle plane, inner circular cambered surface and bottom rectangle face.
A kind of battery-driven car servant brake is with hole with lock brake plate sleeve, it is characterized in that on the brake plate sleeve body (2) of brake plate sleeve (1), having lockhole (3), lockhole (3) is made up of outer circle cambered surface (4), sidewall rectangle plane (5), inner circular cambered surface (6) and bottom rectangle face (7), the outer circle cambered surface (4) of both sides is connected with side walls rectangle plane (5) respectively, side walls rectangle plane (5) is connected with the inner circular cambered surface (6) of both sides respectively, the inner circular cambered surface (6) of both sides is connected with bottom rectangle face (7) both sides respectively, constitutes lockhole (3).
The utility model battery-driven car servant brake is the brake plate sleeve that has some lockholes that is sleeved on the brake disc outer ring with band latch arm hole brake plate sleeve, and brake plate sleeve and brake disc can be integral part by being welded to connect.
In order to reduce the stress concentration at lockhole place, increase lockhole intensity, should do specific design for the geometric configuration of opening the lockhole on the brake plate sleeve body and structure.
This battery-driven car servant brake is the annular arrangement brake plate sleeve with hole with lock brake plate sleeve, and uniform some lockholes that have on the brake plate sleeve body can be inserted in the lockhole the preceding locking bar of servant brake lock core, realize the lock lock, when locking bar withdraws from lockhole, then realizes unblanking.
This battery-driven car servant brake is all opened in the same side of brake plate sleeve body with each lockhole of hole with lock brake plate sleeve, and the interval radian between adjacent two lockholes equates.Each lockhole constitutes by two outer circle cambered surfaces, two sidewall rectangle planes, two inner circular cambered surfaces and bottom rectangle face, and two outer circle cambered surfaces are symmetrical, two sidewall rectangle planes are symmetrical, and two inner circular cambered surfaces are symmetrical, all are symmetrical in the bottom rectangle face.
The utility model battery-driven car servant brake is a lockhole intensity height with hole with lock brake plate sleeve advantage, long service life.
Description of drawings:
Fig. 1: be brake plate sleeve (1) schematic three dimensional views.
Fig. 2: look scheme drawing for brake plate sleeve (1) is main.
Fig. 3: for brake plate sleeve (1) in Fig. 2 A-A to elevational schematic view.
The specific embodiment:
Referring to Fig. 1, Fig. 2 and Fig. 3, among each figure: (1) is brake plate sleeve, and (2) are the brake plate sleeve body, (3) be lockhole, (4) are the outer circle cambered surface of lockhole (3), and (5) are the sidewall rectangle plane of lockhole (3), (6) be the inner circular cambered surface of lockhole (3), (7) are the bottom rectangle face of lockhole (3).
Lockhole (3) is made up of outer circle cambered surface (4), sidewall rectangle plane (5), inner circular cambered surface (6) and bottom rectangle face (7), the outer circle cambered surface (4) of both sides is symmetrical, be connected with side walls rectangle plane (5) respectively, side walls rectangle plane (5) is also symmetrical, and be connected with the inner circular cambered surface (6) of both sides respectively, the outer circle cambered surface (6) of both sides is connected with bottom rectangle face (7) both sides respectively, and symmetrically.
