Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the detailed description is intended only to teach one skilled in the art how to practice the invention, and is not intended to be exhaustive or to limit the scope of the invention.
Referring to fig. 1 to 4, unless otherwise specified, a denotes an axial direction of the torque limiting device, which axis direction a coincides with an axial direction of the cap 10 in the torque limiting device; r denotes a radial direction of the torque limiting device, which corresponds to a radial direction of the cover 10 in the torque limiting device; c denotes a circumferential direction of the torque limiting device, which coincides with a circumferential direction of the cover 10 in the torque limiting device.
Referring to fig. 1 to 3, the torque limiting device according to the present invention includes a cover 10, a driven plate 21, a pressure plate 30, a disc spring 40, and a leaf spring 50.
The torque limiting device can be used, for example, in a vehicle, in particular a hybrid vehicle, in which the cover 10 is intended to be connected in a rotationally fixed manner (non-rotatable manner) to a flywheel at the output of the engine, and the driven disk 21 is intended to be connected in a rotationally fixed manner to a transmission or an electric machine.
Alternatively, the driven plate 21 includes friction plates, which are located at the outer peripheral portion.
It will be appreciated that although in most cases power is transmitted from the engine end to the transmission end in the vehicle, it is possible that power may be transmitted from the transmission end to the engine end in different modes of operation and therefore the driven disc 21 is not necessarily a driven component and may be a driving member with respect to the cover 10. For convenience of description, the connection relationship and the operation principle of the cover 10 and the driven plate 21 will be described by taking a power transmission path from the engine side to the transmission side as an example.
The cover 10 includes a cover main body 11 and a hook 12.
The cover body 11 has an annular disk shape, and a plurality of hooks 12 projecting radially inward are formed on the outer peripheral portion of the cover body 11. The plurality of hook portions 12 are distributed at intervals in the circumferential direction C.
The hook portion 12 is formed integrally with the cover main body 11. For example, the hook portion 12 is formed by punching and bending the cover main body 11. Alternatively, the hook may also be a separate component, such as a pin or ring stop, that is connected or attached to the cover body 11.
The end wall 110 of the cover body 11 at the axial end portion and the hook portion 12 form an accommodation space for at least partially accommodating the friction plates, the pressure plate 30, and the disc spring 40.
Specifically, the pressure plate 30 presses the friction plates of the driven plate 21 against the end wall 110, or the friction plates are sandwiched between the pressure plate 30 and the end wall 110. The pressure exerted by the pressure plate 30 against the friction plates is provided by a belleville spring 40.
The outer peripheral portion of the disc spring 40 abuts against the hook portion 12 to obtain a fulcrum located at the outer peripheral portion; the inner peripheral portion of the disc spring 40 abuts against the pressure plate 30 to obtain a fulcrum located at the inner peripheral portion.
Alternatively, referring to fig. 1 and 3 together, the outer peripheral portion of the disc spring 40 is formed with spoke-like finger portions 41 extending radially outward. The finger 41 is engaged with the hook 12 and abuts against a surface of the hook 12 facing the end wall 110. The width of the finger 41 is substantially equal to the width of the hook 12 in the circumferential direction C.
Optionally, a plurality of convex structures are formed on the surface of the hook 12 facing the finger 41, and the convex structures can limit the finger 41 in the circumferential direction C and the radial direction R; alternatively, the face of the hook 12 facing the finger 41 is formed with a recess in which the finger 41 can be received to position the belleville spring 40 relative to the cap 10 in the circumferential direction C and in the radial direction R.
The fingers 41 have an outer diameter greater than the inner diameter of the hook 12. Since both the fingers 41 and the hooks 12 are discontinuous in the circumferential direction C, during installation, the fingers 41 can be extended in the axial direction a between the hooks 12 and the end wall 110 by inserting them through the spaces between adjacent hooks 12. Thereafter, the disc spring 40 is rotated in the circumferential direction C so that the finger portions 41 are aligned with the hook portions 12 in the circumferential direction C.
It is further preferred that the outer peripheral portion of the disc spring 40 has, in addition to the finger 41 which engages with the hook 12, an abutment portion extending in the axial direction which can be pressed against the pressure plate 30 in the region of the outer peripheral portion of the disc spring 40.
By adjusting the size (e.g., the degree of deformation) of the disc spring 40, the axial pressure applied by the pressure plate 30 to the friction plates can be adjusted, thereby adjusting the maximum static friction force to which the friction plates are subjected (i.e., the static friction force from the pressure plate 30 and the cover main body 11 to which both sides of the friction plates are subjected during operation of the torque limiting device to transmit torque). The static friction force corresponds to an upper limit value of the torque transmittable by the torque restriction device.
When the torque of the input end (for example, the cover 10) is less than or equal to the upper limit value, the cover 10 and the friction plate do not rotate relatively, and the torque received by the output end (the driven plate 21) is equal to the torque of the input end. When the torque of the input end is larger than the upper limit value, the cover 10 and the friction plate generate friction and rotate relatively, and the torque received by the output end is equal to the upper limit value.
The pressure plate 30 is connected to the cover 10 by a plurality of leaf springs 50. In the present embodiment, 3 leaf springs 50 (see fig. 4) are connected between the pressure plate 30 and the cover 10, and the three leaf springs 50 are provided at even intervals (at 120 ° intervals) in the circumferential direction C.
Leaf spring 50 is arcuate with one end 51 fixed to pressure plate 30, such as by a rivet, and the other end 52 fixed to end wall 110, such as by a rivet.
The leaf springs 50 give a certain elasticity between the pressure plate 30 and the cover 10 in the axial direction a, transmit torque in the circumferential direction C without relative rotation, and the plurality of leaf springs 50 distributed in the circumferential direction C also help the pressure plate 30 to complete centering with respect to the cover 10.
It should be appreciated that the present application also provides a torque transfer device and a vehicle including the torque limiting device.
The torque transmitting device includes a torque limiting device and a damping member 20.
The driven disc 21 is connected to the damping member 20. The damping part 20 comprises a damping spring 22, a flange and a side plate, the damping spring 22 being arranged between the flange and the side plate in a torque-transmitting manner. One of the flange and the side plate is connected to the driven plate 21, and the other of the flange and the side plate is connected to the shaft portion 23.
The invention has at least one of the following advantages:
(i) the torque limiting device has the advantages of simple structure, small number of parts, convenience in installation and low cost.
(ii) The platen 30 and the cover 10 are conveniently positioned and are not easy to slip due to relative rotation during operation.
Of course, the present invention is not limited to the above-described embodiments, and those skilled in the art can make various modifications to the above-described embodiments of the present invention without departing from the scope of the present invention under the teaching of the present invention. For example:
(i) the belleville springs 40 may be replaced by another elastic member or members capable of providing an elastic force in the axial direction a, which is also referred to as a first elastic member in the present invention.
(ii) The leaf spring 50 may be replaced by one or more other elastic members capable of providing an elastic force in the axial direction a, which are also referred to as second elastic members in the present invention.
(iii) The torque limiting device according to the present application can also be applied to other torque transmission systems or power transmission systems in which the cover 10 is connected to the first member and the driven plate 21 is connected to the second member, thereby transmitting torque having an upper limit value between the first member and the second member.
With the torque limiting device in the above-described embodiment,
(i) although in the torque limiting device in the above-described embodiment, the cover 10 is the input member and the driven plate 21 is the output member, alternatively, it may be provided that the driven plate 21 is the input member connected to the engine and the cover 10 is the output member connected to the damper member at the rear end.
(ii) Although in the torque limiting device in the above described embodiment the pressure plate 30 is connected to the cover 10 by means of a second elastic member, in particular a leaf spring 50, it may alternatively be connected by means of a non-elastic member, such as a pin or the like, ensuring a synchronous torque transmission between the pressure plate 30 and the cover 10.
