Description

A kind of brake tester
Technical field
The present invention relates to a kind of brake tester is and in particular to a kind of brake tester.
Technical background
Brake is that have to make moving component(Or movable machinery)Deceleration, stopping or the dress keeping the functions such as halted state Put, it is mainly made up of frame processed, brake component and manipulation device etc..General brake is required for brake tester before use and surveys Try the performances such as its moment of torsion, moment.Existing brake tester is by oscillating cylinder 2, swings jar support 3, transition frame 4 and measurement mould Block 6 grade forms(As shown in Figure 1), wherein oscillating cylinder offer moment of torsion, swing jar support and be mainly used in supporting oscillating cylinder, transition frame is The output torque of oscillating cylinder is passed to by test specimen brake.Brake drum and brake component two parts, system are divided into by test specimen brake Dynamic drum is produced by the shoe plate tensioner action being arranged in brake with brake component and interacts, i.e. frictional damping.Oscillating cylinder master If relying on four to be bolted on swing jar support, in oscillating cylinder output high pulling torque, reversing occurs in oscillating cylinder, thus meeting Shear this four fixing bolts, there is potential safety hazard.Further, since transition frame is integrally fixed on underframe, its insufficient rigidity, it is subject to Occur when power is excessive and rock shakiness, can deform when serious, affect result of the test.
In addition, the lever arm of measurement module is erected on support by rotating shaft, rotating shaft is not fixed by its upper end using Kazakhstan, But due to rotating shaft can be led to when Ha Fu tightens to be held tightly, lead to lever arm cannot smooth rotate, and lever arm just cannot rotate then Radial pressure transducer can not be compressed, thus torque value can not be measured, largely effect on certainty of measurement.In addition, measurement stand Rigidity, when doing large-tonnage brake test, measurement stand is easily deformed, and can affect test result.
Content of the invention
In order to solve the above problems, the present invention provides a kind of brake tester, greatly strengthen the carrying energy of testing stand Power, eliminates potential safety hazard, improves the test result of brake tester.
A kind of brake tester, including the oscillating cylinder being installed on swing jar support, brake, brake drum and measurement mould Block, described swing jar support and measurement module are all installed on base, and described swing jar support is made up of gripper shoe and base plate L-shaped structure, the outer face of described gripper shoe offers the groove matching with the termination of oscillating cylinder, and described oscillating cylinder is stuck in recessed Groove is interior and is bolted in gripper shoe;The bearing block group being connected by connecting shaft, described company are installed with described base plate One end of spindle is connected with oscillating cylinder by shaft coupling, the other end is connected with measurement module by brake.
Scheme further, described base plate includes upper plate and lower shoe, is installed with perpendicular in the middle of upper plate and lower shoe Plate and horizontal bar plate, described upper plate, riser and lower shoe all with support plate weld;Described riser and horizontal bar plate are in " non-" font row Cloth, is provided with lagging between riser;The inner face of described gripper shoe is connected with upper plate by connecting plate.
Scheme further, described bearing block group is bolted on the base plate swinging jar support by key after being positioned On;Described swing jar support, measurement module are bolted on base after all being positioned by key.
Scheme further, the brake drum of described brake is passed through braking drum flange and is connected with connecting shaft, described brake Brake component is connected with measurement module by brake component flange.
Scheme further, described measurement module includes radial pressure transducer and the lever arm being located on measurement stand, The center of described lever arm is provided with flange shaft, the two ends of described flange shaft respectively with the bearing block being symmetrically installed on measurement stand Connect.
Scheme further, the length of described lever arm is 800mm.
During use, first pass through shake handwheel, after making measurement module slide into specified location on base, be fixed by bolts to On base.Then brake to be measured is put in the test of the present invention, its brake drum passes through to brake drum flange with connecting shaft even Connect, the brake component of brake is connected with the flange shaft of measurement module by brake component flange.Open oscillating cylinder, the output of oscillating cylinder Moment of torsion passes to brake through shaft coupling, connecting shaft, then passes to lever arm through flange shaft, so that lever arm is rotated and compresses spoke Formula pressure transducer, then passes through to read the numerical value of radial pressure transducer, further according to the torque arm length of known lever arm, Just transmitted torque value can be extrapolated.
Oscillating cylinder support Design l-shaped strong construction, oscillating cylinder are passed through shaft coupling and connecting shaft and brake by the present invention Connecting, making the transmission of moment of torsion more direct and lossless, thus improve test accuracy;And eliminate transition bracket, significantly Ground strengthens testing stand bearing capacity, makes the structure more integration of testing stand simultaneously.
Swing jar support in the present invention is integrally L-shaped, and gripper shoe passes through connecting plate and upper plate reinforcement of weld, horizontal bar plate And riser is welded between upper plate and lower shoe in " non-" font, greatly enhances rigidity and the intensity of base plate.In stress When, swing jar support will not produce and rock or deform, and improve the testing result to brake.The outer face of gripper shoe opens up Groove just oscillating cylinder is stuck in this groove, then with bolt fastening, thus the torsion of oscillating cylinder can be stoped effectively, eliminate Potential safety hazard, improves the bearing capacity of testing stand.Upper plate, riser and lower shoe all with support plate weld, improve entirety Intensity, make oscillating cylinder in output torque, will not produce and rock.In addition, all offering square hole on upper plate and lower shoe, side Welding, and simultaneously alleviate swing jar support overall weight.
In the present invention, measurement module adopts bearing block to replace former not structure of breathing out so that lever arm rotation is smooth, will not produce Tighten the situation of Ha Fu and locking lever arm;And lever arm is lengthened to 800mm by original 500mm, this makes bearing block The power of tumbling being subject to reduces 37.5%, and whole stand stress reduces, and test proves that lever arm lengthens and makes whole stand more stable.
