Abstract
The invention discloses a connection structure of a motor and a transmission system for a direct-drive electric coach. The connection structure comprises a motor spindle (1), a shaft sleeve (2) and a flange plate (3). A shaft extension(4) of the spindle (1) has a conical degree; symmetrical flat key slots are formed in the conical surface of the shaft extension(4); a shaft head (5) is arranged on the end part of the shaft extension(4); an outer thread is arranged on the excircle surface of the shaft head (5); the shaft sleeve (2) is matched with the shaft extension(4) through connection of a flat key; the shaft head (5) is connected with a fixed nut (6) via a thread; the shaft sleeve (2) is connected with the flange plate (3) through a bolt; a rubber pad (7) is arranged between the shaft sleeve (2) and the flange plate (3), and a double end stud (8) connected with a coupler is arranged on the flange plate (3). The connection structure disclosed by the invention has the advantages that the distance between the shaft extension (4) and the flange plate (3) can be conveniently adjusted, and the transmission efficiency and transmission security of the motor can be ensured.
Description
Technical field
The present invention relates to a kind of connection set, be specifically related to automobile-used motor of a kind of direct drive electric big bus and transmission system linkage structure.
Background technique
Direct drive electric big bus motor vehicle drive system directly drives automobile main reducer with motor, and is middle through the universal joint connection.The automobile-used motor of conventional direct drive electric big bus, shaft extension adopts modes such as spline or optical axis directly to be connected with universal joint more.When with motor mounting point and gearbox fixedly the time, the motor shaft extensibility is promptly confirmed.The variation of gearbox or motor position will cause motor to be connected difficulty with universal joint, even can't powered vehicle.In addition, length of shaft can influence performance index such as amount of deflection and the intensity of axle, when situation is serious, possibly cause a gross distortion even fracture.
Summary of the invention
The object of the invention promptly is to overcome the deficiency of existing technology, and a kind of automobile-used motor of direct drive electric big bus and transmission system linkage structure of being convenient to regulate the distance between shaft extension and the universal joint is provided.
The object of the invention is realized through following technological scheme:
Automobile-used motor of direct drive electric big bus and transmission system linkage structure, it comprises electric machine main shaft, axle sleeve and flange plate, the shaft extension of main shaft has tapering; Offer the flat key groove of symmetry on the conical surface of shaft extension; The end of shaft extension is provided with spindle nose, and the periphery of spindle nose is provided with outside thread, and axle sleeve connects through flat key and cooperates with shaft extension; Spindle nose is threaded with set screw nut, and axle sleeve is connected with flange plate through bolt.
Be provided with rubber pad between axle sleeve and the flange plate.
Flange plate is provided with the stud that is connected with coupling.
The invention has the advantages that:
1. only need can regulate the distance between shaft extension and the flange plate, make the layout of motor and gearbox more flexible with the axle sleeve that changes different size;
2. can guarantee that electric machine main shaft is connected with the effective of universal joint, guarantee the transmission efficiency and the transmission Security of motor;
3. be provided with rubber pad between flange plate and the axle sleeve, can effectively prevent the electromagnetic induction of motor, guarantee the safe operation of car load connected element.
