The electromobile coupler comprises a motor connecting piece (1) and a speed changer connecting piece (2), both of which are of a barrel structure. The opposite ends of the motor connecting piece (1) and the speed changer connecting piece (2) respectively extend outwards to form an annular motor connecting disc (3) and a speed changer connecting disc (4), a buffer vibration reduction block (5) is arranged between the motor connecting piece (1) and the speed changer connecting piece (2), the buffer vibration reduction block (5) is made of rubber materials, and the buffer vibration reduction block (5) is bonded with the motor connecting piece (1) and the speed changer connecting piece (2). According to the electromobile coupler, a rubber piece is utilized for performing buffering, limiting is carried out through combination of a limiting pin and a kidney-shaped hole, the vibration reduction performance is effectively improved, and the electromobile coupler has the advantages of being simple in structure, long in service life, low in manufacturing cost and the like.
Description
Technical field
The utility model relates to electric motor car component, particularly relates to a kind of coupling that connects electric vehicle motor output shaft and transmission input shaft.
Background technique
Coupling is that two axles for connecting in different institutions make it common rotation with the mechanical parts of transmitting torque.Coupling is generally comprised of two halves, connects respectively with driving shaft and driven shaft.On common electric car, be also to connect motor output shaft and transmission input shaft with coupling, and on common electric car owing to not cushioning with clutch, therefore when motor can cause larger vibrations by transmission of power during to speed changer, in the course of time, the wearing and tearing of motor and speed changer can be caused, on the overall performance of electric motor car and Security, all great impact can be caused.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of electric motor car coupling that can damping.
The technical solution of the utility model is as follows: a kind of electric motor car coupling, comprise motor link (1) and speed changer link (2), this motor link (1) and speed changer link (2) are tubular structure, and in motor link (1) one end termination relative with speed changer link (2), stretch out respectively and form motor land (3) and the speed changer land (4) of ring-type, it is characterized in that: between described motor link (1) and speed changer link (2), be equiped with buffer shock-absorbing piece (5), this bumper and absorbing shock piece (5) is made by rubber material, and this bumper and absorbing shock piece (5) bonds together with motor link (1) and speed changer link (2).
Adopt the coupling of said structure, motor link is connected with motor output shaft, speed changer link is connected with transmission input shaft, during use, motor output shaft drive motor link rotates, thereby drive buffer shock-absorbing piece to rotate, drove the most afterwards speed changer link and transmission input shaft to rotate, because buffer shock-absorbing piece is to be supported by rubber material, when rotating, there is Buckling stress, the power that can transmit motor cushions, and has played the effect of damping, has improved overall performance and the Security of electric motor car.
On described speed changer land (4), offer speed changer waist shaped hole (4a), on buffer shock-absorbing piece (5), also offer snubber block waist shaped hole (5a), this snubber block waist shaped hole (5a) is arranged symmetrically with speed changer waist shaped hole (4a), on described motor land (3), offer attachment hole (3a), in this attachment hole (3a), be equipped with position limit pin (6), and the other end of this position limit pin (6) is through snubber block waist shaped hole (5a) and speed changer waist shaped hole (4a).In use, when motor link rotates, because having produced the position limit pin wearing on twist distortion motor link, moves in snubber block waist shaped hole and speed changer waist shaped hole buffer shock-absorbing piece, when position limit pin turns to snubber block waist shaped hole and speed changer waist shaped hole edge, due to stopping of waist shaped hole, position limit pin cannot continue mobile, has just limited the further deformation of buffer shock-absorbing piece, make the twist distortion of buffer shock-absorbing piece can be not excessive, thereby damage buffer shock-absorbing piece.
In order to improve the balance when spacing to buffer shock-absorbing piece, on described buffer shock-absorbing piece (5), be along the circumferential direction evenly distributed with three snubber block waist shaped holes (5a), on speed changer land (4), also offer three speed changer waist shaped holes (4a) corresponding with three snubber block waist shaped holes (5a) respectively, on motor land (3), offer three attachment holes (3a) corresponding with three snubber block waist shaped holes (5a) respectively.
Beneficial effect: the utility model adopts rubber parts to cushion adopts position limit pin and waist shaped hole spacing in conjunction with carrying out simultaneously, when effectively having improved damping property, has the features such as simple in structure, long service life, low cost of manufacture.
