The stator frame has the advantages of firm connection, small occupied area and safety.
Description
Technical field
The utility model relates to a kind of retarder accessory, and particularly a kind of automobile is with the rotor frame on the retarder.
Background technology
Retarder is a kind of device that is used for the automobile auxiliary braking, along with the speed of automobile is more and more faster, the brake load of automobile is also increasing, particularly on the automobile of frequent local bus that stops and mountain area enforcement, the excessive problem of brake load is more outstanding, if these brake loads are all born by service braking system, will cause brake drum and brake strip overheated, thereby cause the braking efficiency to descend, even stopping power complete obiteration.
The present employed rotor frame of retarder, because the requirement of wiring, all be to adopt the terminal box of fixing a compression molding at the rotor frame perisporium, this terminal box has not only taken certain volume, in loading and unloading and the process used because collision, be easy to fragmentation, cause wire lead drop out or form potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide that a kind of wiring is firm, area occupied is little, and the rotor frame of safety.
In order to achieve the above object, the technical solution of the utility model is: a kind of rotor frame comprises frame body, the frame body middle part is provided with axis hole, also be laid with 8 magnetic core holes on the frame body, also be provided with the junction block that at least one is used to connect wires on the described frame body, and have installing hole on the junction block.
Described junction block is fixedly mounted on the recess of frame body outer.
The distance of described frame body center to junction block outer is less than the distance of the radius maximum of frame body center to frame body outer.
Described junction block is made one with frame body or is fixedlyed connected with frame body.
Described junction block is two and is arranged on the outer of frame body symmetrically with respect to the axis of axis hole, and all has the connection screw on each junction block.
The edge, the outside in each the magnetic core hole on the described frame body is equipped with location notch, and location notch is communicated with the magnetic core hole.
The inboard edge in each the magnetic core hole on the described frame body is equipped with Wire channel in building, and Wire channel in building is communicated with the magnetic core hole.
The place, inboard that is positioned at each Wire channel in building on the described frame body is equipped with the destressing through hole.
The place, next door is provided with the welding arc groove symmetrically about each the magnetic core hole on the described frame body.
After adopting said structure, owing to also be provided with the junction block that at least one is used for wiring on the described frame body, and has wiring hole on the junction block, when mounted only need be with first plug-in mounting insulating case, binding post is installed again,, is not needed to pass through terminal box by terminal-connecting lead, be connected firmly and area occupied little, safety.
