The moving rate of automobile chassis is measured a lot of contents, the limit load that has comprised brake system, the powertrace of engine, the braking curve of brake system etc. project, in these projects, the limit load of brake system normally adopts the increase counterweight to measure, counterweight is added on the gravity sensor, this power passes to automobile as load, normally gravity sensor being suspended on row between test carriage hangs on and tests, in the test process, have certain problem: gravity sensor owing to connect to be expert at and hang on, its swing is larger, and in the test process, there is larger error in the demonstration of data; The swing of gravity sensor has not only affected test data, and is unfavorable for installing additional of counterweight; There is the impaired danger of bump.
The utility model content
The purpose of this utility model is to provide the suspender of gravity sensor in a kind of automobile chassis power test, solve the vibration problems that gravity sensor exists in the present automobile chassis brake system limit load test, reach the raising testing precision, avoid clashing into impaired purpose.
The purpose of this utility model is achieved through the following technical solutions:
The suspender of gravity sensor in a kind of automobile chassis power test, comprise the chassis, the chassis is rectangular, be provided with two columns on the chassis, two columns are parallel to each other, at two column tops crossbeam is installed, is provided with the cavity of vertical direction at described crossbeam, this cavity is along the Axis Extension of crossbeam and run through upper surface and the lower surface of crossbeam.Chassis whole is rectangular, conveniently utilize shaped steel etc. to process, the chassis has certain thickness and weight, both sides on the chassis are equipped with column, column is parallel to each other and is vertical with the chassis, at the column top crossbeam is installed, form gantry frame structure on the whole, be provided with cavity at crossbeam, cavity is take the central point of crossbeam as starting point, extends to both sides along the axis of crossbeam, and cavity runs through the upper surface of crossbeam and the space that lower surface is formed for installing hook, after will linking up with select location, utilize the instrument such as bolt to be fixed on the crossbeam, gravity sensor is installed in hook is upper to be got final product, also can directly gravity sensor be fixed on the crossbeam by screw rod, so, the use that has replaced row to hang, the swing space of gravity sensor is compressed, and less amplitude of fluctuation has also increased the stability of sensor, can reflect more truly test data, also avoid gravity sensor to clash into other object because amplitude of fluctuation is excessive simultaneously and be damaged.
Be provided with a plurality of limited blocks at described crossbeam, limited block covers the cavity top and is connected on the crossbeam of cavity both sides.Further, as further improvement of the utility model, by a plurality of limited blocks are set at crossbeam, limit the usable range of gravity sensor, avoid the slip of gravity sensor, further avoided the larger swing of amplitude.
The fenestral fabric of described chassis for being made by shaped steel.Further, as a kind of improvement of the present utility model, adopt the be welded chassis of fenestral fabric of shaped steel, can form counter-balanced carriage on the chassis, can balancing weight be installed at grid, increase whole weight, avoid its rollover.
The width on described chassis is greater than the height of column.Further, can increase the arm of force of chassis rollover by increasing the mode of chassis width, reach and prevent the purpose of turning on one's side.
The utility model compared with prior art has following advantage and beneficial effect:
The suspender of gravity sensor in a kind of automobile chassis power test of 1 the utility model, be provided with cavity at crossbeam, cavity is take the central point of crossbeam as starting point, axis along crossbeam extends to both sides, cavity runs through the upper surface of crossbeam and the space that lower surface is formed for installing hook, after will linking up with select location, utilize the instruments such as bolt to be fixed on the crossbeam, gravity sensor is installed in hook upward to be got final product, also can directly gravity sensor be fixed on the crossbeam by screw rod, so, the use that has replaced row to hang, the swing space of gravity sensor is compressed, and less amplitude of fluctuation has also increased the stability of sensor, can reflect more truly test data, also avoid gravity sensor to clash into other object because amplitude of fluctuation is excessive simultaneously and be damaged;
