The protective cover body is installed directly above a motor of the automotive chassis dynamometer so that the portion of the motor, exposed out of the ground, is arranged inside the shell of the protective cover body, and heat produced by the motor can be discharged by the ventilation holes. To improve a cooling effect, an air cooling motor can be installed, and the smaller motor can be used to blow the motor of the automotive chassis dynamometer. The protective cover body is simple in structure, capable of being machined by adopting existing processes such as a steel plate stamping process, small in machining difficulty, and low in cost. Meanwhile, the protective cover body has strength to some extent, steel can protect the motor effectively, contact of operating personnel and the motor is avoided, safety of the motor is guaranteed, safety of the operating personnel is guaranteed at the same time, and scalding is avoided.
Description
Technical field
The utility model relates to a kind of assistant tool, specifically refers to the protective housing of road simulation dynamometer.
Background technique
Vehicle testing technique is from the auto repair derives from technology out, is accompanied by the development of automotive engineering by auto repair.In the auto repair process in early days, mainly be to find vehicle failure and do to repair targetedly by experienced maintenance man, namely pass by " hoping (soon) " (for example: by observation automobile appearance or vehicle running state failure judgement) that people often say, " hear (ear is listened) " (such as: by running sounding failure judgement such as motors), " ask (inquiry) (for example: by inquiry drive personnel's vehicle use condition or phenomenon failure judgement); " cutting (hand is touched) " (for example: touch by hand and to experience temperature; vibration; the phenomenon failure judgement such as pressure) mode.Along with the progress of dynamo-electric observation and control technology progress, particularly computer technology of modern times, vehicle testing technique is develop rapidly also.People can rely on various advanced persons' instrument and equipment at present, and automobile is carried out not dissection test, and safety, rapid, reliable.Safety and environmental protection detects and to refer to automobile is carried out the detection that carry out regular and irregular safe operation and environmental protection aspect; Purpose is to set up safety and public hazards monitoring system in not disintegration of automobile situation, guarantees that vehicle has satisfactory outward appearance appearance and good Safety performance, and the environmental of restricting vehicle moves it under safety, efficient and low pollution operating mode.Combination property detects the detection that refers to automobile is carried out regular and irregular combination property aspect; Purpose is in not disintegration of automobile situation, operational vehicle is determined its ability to work and technology status, find out fault or hidden danger position and reason, maintenance vehicle is carried out quality supervision, set up quality supervision system, guarantee that vehicle has good Security, reliability, power character, Economy, exhaust gas purification and noise pollution, to create larger economic benefit and social benefit.
Chassis dynamometer is the special-purpose juice amount equipment for measured automobiles Output power of driving wheel, moment of torsion (or driving force) and rotating speed (or speed), the chassis dynamometer major component is cylinder mechanism, power absorption device, control and measuring system and auxiliary device, the additional fly wheel system of some chassis dynamometer etc., the acceleration performance of all right measured automobiles, sliding performance etc.Present road simulation dynamometer normally is installed in the below ground between inspection vehicle, only basseted in the wheel position of its test, in the space that all the other integral body all locate below ground level, so have one and be easy to unheeded problem: road simulation dynamometer is by driven by motor, particularly in the continuous operation process, can produce a large amount of heats in the course of the work, heat build-up can raise ambient temperature at below ground, the result who causes is exactly the steel oxidation speed quickening of below ground, directly shortened whole working life, simultaneously, also greatly shorten the working life of electrical equipment.
The model utility content
The purpose of this utility model is to provide a kind of protective housing of road simulation dynamometer, the heat that the motor of present road simulation dynamometer is produced discharges, guarantee simultaneously the safety in use of motor, reach the purpose that increases the road simulation dynamometer whole service life.
The purpose of this utility model is achieved through the following technical solutions:
The protective housing of road simulation dynamometer comprises shield body, and shield body is made of an end face and four sides, and its integral body is rectangular-shaped housing, is provided with a plurality of vent holes in described shield body.Road simulation dynamometer integral body is placed on below ground, only its motor position is exposed a part more than ground, at this position shield body is installed, shield body integral body is cuboid, or the shape after the cuboid cutting, it is enclosed by four sides and end face and forms, be provided with a plurality of vent holes at end face and side, during use, with shield body be installed in the road simulation dynamometer motor directly over, make the motor that bassets partly be positioned at the housing of shield body, the heat that motor produces can be discharged by vent hole, in order to strengthen cooling-down effect, ventilated machine can be installed, blow the motor of road simulation dynamometer with less motor.Shield body simple in structure; can adopt the existing processes such as steel plate punched technique; difficulty of processing is little; cost is lower, and shield body has certain intensity, and steel can effectively be protected motor; avoid operator to contact with motor; guaranteed the safety of motor, guaranteed simultaneously operator's safety, avoided scalding.
Described vent hole is positioned at end face and three sides of shield body.Further, as further improvement of the utility model, adopt vent hole to be distributed in the form of end face and three sides, not being provided with the position that the side of vent hole is connected with end face can suitably reduce the quantity of vent hole or vent hole is not set, can effectively lead to wind direction, so that the wind direction when using is fixed, can maximum magnitude ground be blown over from the motor surface of road simulation dynamometer by cold wind, reach the purpose of lowering the temperature as far as possible.
Be circular, oval or rectangle at described vent hole.Further, motor surface for fear of hot air from road simulation dynamometer does not form eddy current after passing vent hole, and circular, ellipse or rectangle are as vent hole, and not only processing technology is simple, and can prevent effectively that hot air from forming eddy current, improves radiating efficiency.
The utility model compared with prior art has following advantage and beneficial effect:
The protective housing of 1 the utility model road simulation dynamometer, with shield body be installed in the road simulation dynamometer motor directly over, make the motor that bassets partly be positioned at the housing of shield body, the heat that motor produces can be discharged by vent hole, in order to strengthen cooling-down effect, ventilated machine can be installed, blow the motor of road simulation dynamometer with less motor, shield body simple in structure, can adopt the existing processes such as steel plate punched technique, difficulty of processing is little, and cost is lower, shield body has certain intensity, steel can effectively be protected motor, avoid operator to contact with motor, have guaranteed the safety of motor, guaranteed simultaneously operator's safety, avoided scalding;
