Description
Technical field
The utility model relates to a kind of wet friction clutch that is mainly used in transmission device in transmission system of engineering vehicle system, the boats and ships transmission system, belong to mechanical transmission clutch technical field.
Background technique
Shown in Fig. 1,2, existing wet-type multi-chip friction clutch mainly is comprised of parts such as inner attrition piece 11, outside friction disc 12, clutch outer member 13, piston 14, return spring 15, back-up rings, inner attrition piece 11 is rigidly connected by spline and a gear, outside friction disc 12 is connected with clutch outer member 13, clutch outer member 13 and axle 16(or gear) be connected.
When to the logical pressure oil of clutch, pressure oil moves axially the thrust that pushing piston overcomes return spring, and inside and outside friction plate is compressed, because the effect of frictional force, it is as a whole that interior outside friction disc will become, and from then on power can transmit.This state is the clutch combination.
When cutting off the pressure oil that leads to clutch, the return spring pushing piston moves to the direction of unclamping interior outside friction disc, and the axial free play of interior outside friction disc, interior outside friction disc rotate with connected gear (or axle) separately, and from then on power cannot transmit.This state unclamps on clutch.
In the prior art, when needing transferring power between clutch outer member and the axle, clutch outer member and axle be connected with dual mode, a kind of is to connect by interference, this moment clutch outer member structure as shown in Figure 1; Another kind is that clutch outer member is connected with bolt with gear, then utilizes gear inner spline to be connected with axle, as shown in Figure 2.
The structure of clutch outer member shown in Figure 1, the necessary gear shaping of its internal spline, manufacturing efficiency is low, is unfavorable for batch production.Clutch outer member is connected the restriction that is limited by hot jacket (perhaps shrinkage) temperature with the interference of axle, transmission capacity is little.
In the clutch configuration shown in Figure 2, clutch outer member still needs gear shaping, and manufacturing efficiency is low, is unfavorable for batch production.Piston seat and gear often are subject to the restriction that this place does not have gear to exist with bolted structure to its applications the time.
The model utility content
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of rational in infrastructure, and is easy to use, reliable, is suitable for producing in enormous quantities, improves the wet-type multi-chip friction clutch of transmission of power ability.
The purpose of this utility model is finished by following technical solution, it mainly is comprised of inner attrition piece, outside friction disc, clutch outer member, clutch base, piston, return spring, described inner attrition piece is rigidly connected by spline and a gear, outside friction disc is connected with clutch outer member, clutch outer member and clutch base are by being welded to connect, and described clutch base and transmission shaft pass through spline joint.
The rear welding 31 that cooperatively interacts of the cylindrical of the endoporus of described clutch outer member 23 and described clutch base 24, the diameter of bore D1 of wherein said clutch outer member 23 is greater than the large footpath of internal spline; The transmission shaft of described installation clutch base 24 comprises one section optical axis and one section axle that is provided with spline, and wherein the large footpath of spline is less than the diameter of axle of described optical axis.
The utility model is the structure innovation that carries out on the basis of existing technology, it has rational in infrastructure, easy to use, reliable, be suitable for producing in enormous quantities, can when making in batches, boost productivity, can improve the transmission capacity between axle and the clutch outer member, the characteristics such as flexibility that clutch is arranged in the time of improving transmission design.
Description of drawings
Fig. 1 is a kind of structural representation of prior art.
Fig. 2 is the another kind of structural representation of prior art.
Fig. 3 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 3, the utility model mainly is comprised of inner attrition piece 21, outside friction disc 22, clutch outer member 23, clutch base 24, piston 25, return spring 26, described inner attrition piece 21 is rigidly connected by spline 27 and a gear 28, outside friction disc 22 is connected with clutch outer member 23, clutch outer member 23 and clutch base 24 are by being welded to connect, and described clutch base 24 is connected by spline 30 with transmission shaft 29.
The rear welding 31 that cooperatively interacts of the cylindrical of the endoporus of described clutch outer member 23 and described clutch base 24, the diameter of bore D1 of wherein said clutch outer member 23 is greater than the large footpath of internal spline; The transmission shaft of described installation clutch base 24 comprises one section optical axis and one section axle that is provided with spline, and wherein the large footpath of spline is less than the diameter of axle of described optical axis.
The utility model is designed to use broaching tool to process the structure of internal spline clutch outer member, makes it be more suitable for producing in enormous quantities; For structure shown in Figure 1, the structure that the utility model uses the piston seat spline to be connected with axle solves the problem that interference connects the transmission capacity deficiency; And when promoting to other applications for Fig. 2 structure, can solve the structure problem that does not have gear to exist herein.
When to the logical pressure oil of clutch, pressure oil moves axially the thrust that pushing piston overcomes return spring, and inside and outside friction plate is compressed, because the effect of frictional force, it is as a whole that interior outside friction disc will become, and from then on power can transmit.
When cutting off the pressure oil that leads to clutch, the return spring pushing piston moves to the direction of unclamping interior outside friction disc, and the axial free play of interior outside friction disc, interior outside friction disc rotate with connected gear (or axle) separately, and from then on power cannot transmit.
Wherein, clutch outer member and piston seat are by being welded and fixed, and the aperture D1 that clutch outer member matches with piston seat is greater than the large footpath of internal spline, and clutch outer member can adopt Broaching Technology to process like this, can improve the manufacturing efficiency when making in batches.
Piston seat adopts spline to be connected with axle, can improve transmission capacity like this.Designed simultaneously the optical axis of one section transition fit, so that clutch pressure oil does not leak when entering clutch in the axle.The large footpath of piston seat internal spline is less than the diameter of axle D2 of its left side transition fit optical axis, and the piston seat internal spline can adopt Broaching Technology to process like this, can improve the manufacturing efficiency when making in batches.
