Abstract
The utility model discloses a two speed transmission for an electrocar, comprising a motor (1) and a speed shifting mechanism arranged in a gear box body (2) of the transmission, wherein the motor (1) is connected with the speed shifting mechanism and is a non-speed reduction motor. By adopting the technical scheme, the two speed transmission has the advantages that the structural design is ingenious, the assembly is convenient, and the service life of the motor is long, so that the two speed transmission can provide enough output torque under the condition that the speed of the motor is relatively high.
Description
Technical field
The utility model relates to a kind of electric vehicle transmission, particularly a kind of electric motor car two speed transmission.
Background technique
The utility model patent that a kind of name is called " the afterburning speed change back axle of electric motor car " is disclosed in CN201457044U, it comprises the inner rotary member that is arranged in the rear axle housing body, inner rotary member is provided with the output gear that is connected with inner rotary member, the semiaxis tooth that passes through of inner rotary member is connected with semiaxis, back axle is provided with the gear that is connected with motor, and the selector device that is connected with gear.Its adopts reducing motor as power source, though do so feasible, owing to reducing motor in use, internal gear damages easily, greatly reduces working life; If adopt unmoderated motor as power source, such gear transmission structure makes that again output torque is not enough, the electric motor car difficulty of travelling.
The model utility content
The purpose of this utility model just provides the high electric motor car two speed transmission of a kind of output torque.
The purpose of this utility model is to realize by such technological scheme, and a kind of electric motor car two speed transmission comprises motor, is arranged on the gear in the transmission gear casing, and described motor is connected with gear, and described motor is reducing motor not.
Above-mentioned gear comprises tooth axle I and the tooth axle II that is set in parallel in the transmission gear casing, tooth axle I is provided with high speed driving tooth and low speed driving tooth, described high speed driving tooth and low speed driving tooth mesh with the high speed driven tooth and the low speed driven tooth that are arranged on the tooth axle II respectively, at the synchronizing ring tooth and the output driving tooth that is close to the high speed driven tooth that also are provided with on the tooth axle II between high speed driven tooth and low speed driven tooth, described tooth axle I connects with motor output shaft.
Produce for convenience, reduce the manufacture cost of gear, described high speed driving tooth, low speed driving tooth, high speed driven tooth, low speed driven tooth, synchronizing ring tooth and output driving tooth are cylindrical gears.
Owing to adopted technique scheme, the utlity model has that structural design is ingenious, easy to assembly, the advantage of motor long service life, use it to make and faster under the condition, provide enough output torques at motor speed.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
