Abstract
A hydraulic disc-type dynamometer mainly comprises a transmission shaft, a shell portion, a braking portion, a braking disc, a bearing, a bearing cover and a force arm rod. The shell portion comprises a box body and a box cover, the box body is provided with a through hole for allowing a hydraulic oil pipe to enter and exit, the braking portion comprises the braking disc, a braking caliper and two friction plates. The friction force between the friction plates and the braking disc is changed by controlling the size of the pressure of input hydraulic oil, and therefore the loading force of the hydraulic disc-type dynamometer is changed. The hydraulic disc-type dynamometer is small in size, simple and compact in structure, low in cost, low in energy consumption, easy to install and disassemble, convenient to control, economical and practical.
Description
Technical field
The present invention relates to the technical field of automobile test, is a kind of hydraulic disc formula dynamometer machine.
Background technology
At present, in the technical field the inside of automotive testing equipment, simulated road test charger type is a lot, such as hydraulic dynamometer, electric eddy current dynamometer, electric dynamometer etc., these equipment are that volume is large a bit, load the adjusting time long, measuring accuracy is low, or price is too high, complex structure, difficulty etc. is installed, as high in electric eddy current dynamometer cost, power consumption is large, control relative complex etc., therefore, the present invention designs and produces a kind of hydraulic disc formula dynamometer machine, for the road load of determining of automobile is tested, determine anti-test and the travel load test aspect of dragging of moment a kind of economical and practical product is provided.
Summary of the invention
The object of the invention is to design that a kind of volume is little, simple and compact for structure, cost is low, low energy consumption, easily installation and removal, conveniently control, hydraulic disc formula dynamometer machine that practicality is good.Its working method is: transmission shaft output torque, drive brake puck rotates, housing parts is motionless, meanwhile, along with the hydraulic fluid pressure that is input to hydraulic cylinder slowly increases, hydraulic oil promotes piston, thereby promote the second friction disc and draw close and clamp gradually brake puck to the first friction disc direction, brake puck, under the friction force effect of the first friction disc and the second friction disc, absorbs the power of automobile output shaft, realizes the load test of simulative automobile road.
In order to realize above-mentioned functions, the present invention has adopted following technical scheme: hydraulic disc formula dynamometer machine, is mainly made up of transmission shaft, housing parts, brake portion, brake puck, bearing, bearing cap, arm bar.Transmission shaft has keyway on termination, can be connected with engine, reductor or output shaft of gear-box; Housing parts comprises casing and case lid, and case lid is connected with casing both sides respectively, offers the through hole of hydraulic oil pipe turnover on casing; Bearing inner ring is enclosed within on transmission shaft, and outer shroud is arranged on the case lid of both sides; Bearing cap is connected with case lid; Brake portion comprises caliper, the first friction disc, the second friction disc, piston, and the first friction disc and caliper left side are connected, and the second friction disc is connected with piston, and piston and caliper right side form hydraulic cylinder, and annular seal space right side is provided with oil-in; Brake puck is connected with transmission shaft disk, is installed between the first friction disc and the second friction disc; Caliper is connected with case lid; Arm bar and casing are connected, and are horizontal, and have connecting through hole on arm bar, can be connected with external tension-compression sensor.
The outstanding advantage of the present invention is as follows: the present invention utilizes hydraulic oil pressure to drive the friction disc of caliper so that transmission shaft is loaded, its project organization compactness, easy and safe to operate, overall volume little, easy for installation simple, cost is low and energy consumption is little, be convenient to reduce maintenance cost and improve measuring accuracy, and the control of hydraulic pressure and easy to adjust, practicality is good.
