Description
Technical field
Mechanical manufacturing field of the present invention, is specifically related to a kind of clearance self-adjusting device for multi-disk wet brake.
Background technique
Current wet type bridge adopts enclosed multi-disc wet type break, widely uses and work under bad environment and the special car that needs braking moment larger.Multi-disk wet brake is by hydraulic drive piston thus the raw braking moment of pressing friction by-product realizes braking, vehicle in use frequently can be braked and cause friction pair constantly to wear and tear, brake clearance can increase thereupon, piston stroke also can increase gradually, cause needing liquid measure to increase gradually during braking, even make piston movement stroke exceed setting stroke and make braking failure, thus threaten traffic safety.Therefore, when ensureing braking, piston keeps stable brake clearance to be vital, and keep brake clearance constant, what need to continue adjusts brake clearance.This device can automatic regulating brake gap to setting value.
The principle being generally applicable to multi-disk wet brake lash adjusting device is greater than the returning place force of piston to provide stable setting brake clearance value for the frictional force between lining and spacer, lash adjusting device at present for multi-disk wet brake relies on the frictional force ensureing lining and spacer between lining and spacer by processing Interference size, first processing accessories also needs high-precision requirement, secondly processing Interference size is relied on to be difficult to ensure stable interference, and this Interference size can be fallen by long-term attrition in Reusability process, thus make the frictional force between lining and spacer reach stationary value, stable compensate for clearance cannot be provided in backlash compensation process, normal work and the driving risk of break may be had influence on.
This device adds elastomer to ensure magnitude of interference stable between lining and elastomer, the frictional force stable between lining and elastomer of principal security, thus can the brake clearance of stably compensation making, so both decrease the machining accuracy of lining, and the wear extent in Long-Time Service process is also extremely small, also extremely convenient in installation process and in maintenance process.Break reliability of operation and traffic safety can be ensured well.
Summary of the invention
The object of the invention is the device in order to provide a kind of a kind of automatic regulating brake gap for multi-disk wet brake, this device adopts elastomer 2 and lining interference to ensure stable frictional force, enable this device stably automatic regulating brake gap to setting value to improve the reliability of break to guarantee traffic safety.
In order to realize foregoing invention object, the invention provides following technological scheme:
A kind of clearance self-adjusting device for multi-disk wet brake comprises lining 1, elastomer 2, sliding sleeve 3, shoulder block 4, compensates pilot pin bolt 5; Elastomer 2 interference is arranged in lining 1; Compensate pilot pin bolt 5 and shoulder block 4 and sliding sleeve 3 and elastomer 2 are installed successively; Described lining 1 is fixedly mounted on piston 6 by shaft block ring; Described elastomer 2 is arranged on lining 1 by interference; Described elastomer 2 is Spielpassung with sliding sleeve 3; Described elastomer 2 can select the various elastic material such as spring pin or rubber pin; Described compensation pilot pin bolt 5 is mounted on break cavity 7;
The elastomer that clearance self-adjusting device of the present invention adopts can be spring pin, rubber pin, it is characterized in that the problem of the brake clearance adjustment solving wet type bridge break, the maintenance setting brake clearance enabling this break more stable, reduces the cost of production of this break and maintenance cost and substantially increases the safety and reliability of vehicle.
Accompanying drawing explanation
Fig. 1 is the structural representation of intermediate gap of the present invention self-reacting device.
Embodiment
As shown in Figure 1, the main parts size being applicable to multi-disk wet brake clearance self-adjusting device is: lining 1, elastomer 2, sliding sleeve 3, shoulder block 4, compensation pilot pin bolt 5; Elastomer 2 interference is arranged on lining 1 Inner; Compensate pilot pin bolt 5 and shoulder block 4 and sliding sleeve 3 and elastomer 2 are installed successively;
When multi-disk wet brake works, piston 6 axially moves, and friction pair 8 compresses the brake clearance of the initial setting between piston 6 and friction pair 8 can be eliminated, and produces braking moment and brakes.
Along with multi-disk wet brake repeatedly brake time, friction pair 8 can produce wearing and tearing, also has wearing clearance when piston 6 moves to the brake clearance of initial setting between each friction pair 8.In order to produce braking moment, piston 6 must continue axial motion and arrive generation braking moment to eliminate secondary 8 of wearing clearance pressing friction.
This device is arranged on piston 6, and when piston 6 moves axially left, elastomer 2 is in the enterprising line slip of sliding sleeve 3, and the frictional force between elastomer 2 and sliding sleeve 3 is less than the thrust that piston 6 carries out axial motion; When exceeding initial setting brake clearance when piston 6 axial motion, elastomer 2 slides into shoulder block 4 place, and now the thrust of piston 6 is still greater than the frictional force between elastomer 2 and lining 1, thus makes to produce between elastomer 2 and lining 1 to slide.
When brake release, piston 6 moves axially to the right under the effect of returning device, frictional force now between elastomer 2 and lining 1 is greater than the power of piston 6 return, and the frictional force between elastomer 2 and sliding sleeve 3 is less than the power of piston 6 return, thus the position of the relatively initial piston 6 in the position making piston 6 return has been moved to the left a segment distance, and the distance that it is moved to the left equals friction pair 8 weares and teares and the gap width produced, thus the brake clearance of the initial setting of multi-disk wet brake is recovered.
By repeatedly braking, under the effect of elastomer 2, lining 1, sliding sleeve 3, the trace wearing and tearing that auto-compensation friction pair 8 produces, keep the brake clearance of initial setting constant.
Last it is noted that obviously, above-described embodiment is only for example of the present invention is clearly described, and the restriction not to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And thus the apparent change of amplifying out or variation be still among protection scope of the present invention.
