Embodiment
For the technical characterstic of this programme can be clearly demonstrated, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
Can be found out by accompanying drawing, a kind of clutch abrasion indicating device, include one end and be fixed on measurement pole socket 3 on boosting cylinder for clutch cylinder body 10, the arranged outside of the other end of described measurement pole socket 3 has indicating piece 1, also comprise a measuring rod 9, this measuring rod 9 successively through described boosting cylinder for clutch cylinder body 10, measure pole socket 3 and indicating piece 1, and one end of measuring rod 9 is positioned at boosting cylinder for clutch matches with boosting cylinder for clutch piston 14; For being flexibly connected between described measuring rod 9 with measurement pole socket 3, measuring rod 9 can be moved relative to measurement pole socket 3, fixed by jump ring 2 between described indicating piece 1 and measuring rod 9, jump ring 2 coupling mechanism force is 20-30N, and the external force applying to be greater than jump ring 2 coupling mechanism force can allow indicating piece 1 way moving on measuring rod 9; And jump ring 2 locking getting loose of effectively can reducing that vibrating fatigue causes.
Described measurement pole socket 3 is provided with the draw-in groove 12 of a side opening, the first through hole and the second through hole 11 is disposed with in the measurement pole socket 3 of this draw-in groove 12 side, be provided with third through-hole 13 in the measurement pole socket 3 of the opposite side of this draw-in groove 12, described measuring rod 9 is successively through the second through hole 11, first through hole (not marking in figure), draw-in groove 12 and third through-hole 13; The measuring rod 9 being positioned at draw-in groove 12 is provided with packing ring 4, the measuring rod 9 being positioned at the first through hole is fixed with locking spring 5, the diameter of described third through-hole 13, the diameter of the second through hole 11 and the diameter of the first through hole reduce successively, measuring rod 9 is fixed in measurement pole socket 3 by locking spring 5 and packing ring 4 by the utility model, compact structure is easily arranged, and can effectively prevent measuring rod 9 from being ejected by boosting cylinder for clutch internal air pressure; The coupling mechanism force of locking spring 5 is 40-60N.
Described measuring rod 9 with between locking spring 5 for interference fit is connected.The outer surface of described measurement pole socket 3 is provided with the one section of screw thread 7 matched with boosting cylinder for clutch cylinder body 10.Be provided with seal ring 6 and seal ring 8 between described measurement pole socket 3 and boosting cylinder for clutch cylinder body 10, be provided with seal ring 15 between described measuring rod 9 and measurement pole socket 3, effectively can ensure sealing.
Using method of the present utility model: as shown in Figure 2, before boosting cylinder for clutch is installed, boosting cylinder for clutch piston 14 is in the rightmost side, and now measuring rod 9 contacts with boosting cylinder for clutch piston 14, and indicating piece 1 contacts with measurement pole socket 3; As shown in Figure 3, servo-cylinder is installed rear boosting cylinder for clutch piston 14 and is moved to left, and measuring rod 9 drives indicating piece 1 to move to left; As shown in Figure 4, promoting indicating piece 1 to the right makes indicating piece 1 contact with measurement pole socket 3, i.e. initialization, as shown in Figure 5, after using, along with driven disc wearing and tearing, boosting cylinder for clutch piston 14 can continue to move to left, indicating piece 1 can produce an intersegmental gap with measurement pole socket 3, measures gap herein and can understand driven disc abrasion condition.
The effect of the utility model indicating piece 1 way moving, be that clutch alignment error (being namely separated the distance of draw ring apart from flywheel) is generally ± (2-4) mm, declutch lever ratio is general at 1.5-2, when causing servo-cylinder initially to be installed like this can there is ± (3-8) mm error in the position of piston, after changing clutch, if indicating piece 1 can only single-way moving, then can not ensure measuring rod 9 and piston contact, boosting cylinder for clutch piston 14 place wearing and tearing stroke is generally 20-25mm, so this error is larger on the impact of instruction accuracy.
By reference to the accompanying drawings the embodiment of model utility is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
