Description
Technical field
The present invention relates to automobile technical field, specifically, is a kind of vibration absorbing coupling that is used on the electric vehicle, is used for connecting between motor and the speed changer.
Background technique
Connecting between the motor of electric vehicle and the speed changer, generally adopt rigid coupling, because of it does not need gearshift, the impact shock that does not have gear shift and brought, the vibration of transmission system is also not too obvious to the influence of motor.Day by day abundant along with the electric vehicle theory, speed changer is replaced by two grades of automaitc shfit or multi-speed transmission, and gear shift produces impact inevitably, and the vibratory impulse that rigid coupling produces can't absorb work between motor and the speed changer time; Moreover the vibration of transmission system itself also can have a negative impact to motor, also can reduce the reliability and the life-span of motor and transmission system component.Because the compact structure of electric motor car, the ordinary elasticity coupling of various types can not directly be selected for use because of problems such as reliability reaches axially, radial dimensions.Therefore, need a kind of coupling of redesign with vibration-damping function, improve effectively connect impact, transmitting movement and torque between the diaxon.
Summary of the invention
The object of the present invention is to provide a kind of vibration absorbing coupling of compact structure, can subdue shifting of transmission effectively and impact, reduce the adverse effect of driveline vibrations, improve the reliability and the life-span of motor and transmission system component motor.
For solving above technical problem, a kind of vibration absorbing coupling provided by the present invention, vibration absorbing coupling, comprise flange plate (1), driven plate (2), dish hub (3), damping disk(-isc) (4) and shock-absorbing spring (5), key is: the right-hand member of described flange plate (1) stretches out into one uncovered (1a), described uncovered (1a) outer rim has the flanging (1b) with flange plate (1) axis normal, and the flanging (1b) of described flange plate (1) is connected by equally distributed first rivet (9) on circumference with driven plate (2); Described dish hub (3) is made of dish hub former (3a) and dish hub core (3b), be set with first damping washer (6) on the dish hub core (3b) in described dish hub former (3a) left side, T-shaped and the left end external diameter of described first damping washer (6) is less than the right-hand member external diameter, and described driven plate (2) is sleeved on described first damping washer (6) the left end excircle and the right side of this driven plate (2) is pressed on the step of first damping washer (6); From left to right be set with second damping washer (7), space washer (10), butterfly spring (8) and damping disk(-isc) (4) on the dish hub core (3b) on described dish hub former (3a) right side successively; Described driven plate (2), dish hub former (3a) have the corresponding strip hole in position in a circumferential direction with damping disk(-isc) (4), described shock-absorbing spring (5) is installed in the described strip hole, connect by equally distributed second rivet (11) on the circumference between described driven plate (2), dish hub (3) and damping disk(-isc) (4) three, described dish hub (3) is driven plate (2) and damping disk(-isc) (4) rotation angle α relatively, and-14 °≤α≤14 °.
Adopt above technological scheme, flange plate is sleeved on the output shaft of drive motor, and the dish hub sleeve is contained on the input shaft of speed changer, links together by the present invention between motor and the speed changer.When motor operation, the output shaft of motor drives flange plate and rotates synchronously, flange plate drives and rotates with its driven plate that is riveted together, because the dish hub is driven plate and damping disk(-isc) rotating certain angle relatively, driven plate compressing shock-absorbing spring, shock-absorbing spring promotion dish hub is rotated, give the dish hub with transmission of power, the final transmission outputs on the speed changer.The impulsive load of driven plate quick rotation is absorbed by damping spring, and shock-absorbing spring has played buffering and rotated the effect of impacting and avoiding torsional vibration generation resonance; The space washer that dish hub former right side is provided with compresses the location to damping washer, and butterfly spring can be adjusted the damping value of damping washer, makes the damping of product uniform and stable.
The right side of above-mentioned space washer (10) is provided with four by the equally distributed projection of circumference (10a), described projection (10a) extends along the axis of space washer (10), and this projection (10a) passes the endoporus of butterfly spring (8) and stretches out from damping disk(-isc) (4).
