The output coupling is composed of an output inner spline shaft and a spring positioning plate, the output inner spline shaft is fixed with the spring positioning plate, the spring positioning plate is provided with a plurality of spring positioning holes, and springs are arranged in the spring positioning holes; and the input coupling is composed of an input inner spline shaft and two spring retainer covers, the input inner spline shaft is fixed with one of the spring retainer covers, the spring retainer covers are provided with a plurality of spring retainer windows, the spring retainer windows correspond to the spring positioning holes arranged on the spring positioning plate, the two spring retainer covers are arranged oppositely, the spring positioning plate is positioned between the two spring retainer covers, the two spring retainer covers are fixed together, the springs arranged on the spring positioning plate are positioned in the spring retainer windows of the two spring retainer covers, the input coupling is connected with the output coupling by the springs to reduce torque impulse in the transmission process.
Description
Technical field
The utility model belongs to a kind of electric vehicle transmission part, the coupling of particularly a kind of motor in electric automobile and speed changer transmission.
Background technique
Electric vehicle has obtained development to a certain degree as a kind of new industry current, and along with development of technology, the applied drive motor power of electric vehicle is also increasing.Owing to adopt inside and outside spline directly to be connected between drive motor and the speed changer, each other without any buffering, therefore, in transmission process, can produce bigger torque pulse, especially when starting, impact to speed changer is bigger, driving gear to speed changer causes bigger infringement, has reduced the working life of speed changer, and, the travelling comfort of automobile acceleration driving is also bad, and the impact noise of generation also is an inevitable problem.
Summary of the invention
The technical problems to be solved in the utility model is, overcomes the existing inside and outside spline coupling of electric vehicle speed changer is impacted big problem, provides a kind of transmission to impact the little motor in electric automobile and the coupling of speed changer transmission.
The utility model is made of output shaft coupling and input coupling, the output shaft coupling is made of output female splined shaft and spring location piece, output female splined shaft and spring location piece are fixed together, several spring positioning ports are arranged on the spring location piece, in the spring positioning port, spring is installed, input coupling keeps lid to constitute by input female splined shaft and two springs, input female splined shaft and one of them spring keep lid to be fixed together, keep having covered several springs at spring and keep window, spring keeps window corresponding with the spring positioning port on the spring location piece, described two springs keep lid to be oppositely arranged, the spring location piece keeps between the lid at two springs, two springs keep lid to be fixed together, the spring that is installed on the spring location piece is arranged in the spring maintenance window that two springs keep lid, input coupling is connected with the output shaft coupling by spring, to reduce the torque pulse in the transmission process.
Little spring also is installed, further to reduce the impact in the running in spring.
Two springs keep lid with rivet together, perhaps are bolted together.
Advantage of the present utility model is, between the spring of input coupling keeps lid and the spring location piece of exporting shaft coupling, spring is set, spring by input coupling keeps lid to give spring with transmission of power, by spring transmission of power is given the spring location piece of output shaft coupling again, spring has played the effect of buffering in the transmitting torque process, eliminated the torque pulse that motor produces, for speed changer provides comparatively mild power input, improve the working life of speed changer driving gear, and reduced the noise that produces owing to impacting.
