Fixed vehicle high speed breaking-in equipment

Abstract

The invention relates to a fixed type automobile high-speed running-in device , which can conveniently simulate the resistance conditions of the automobiles on a real road and causes the automobiles to generate the same effect of pulling to the high speed on a highway, that is, the effect of carbon removal, realization of overall automobile fully running-in and improvement of the overall automobile performance. The concrete run mode is that the automobile parks at the middle position of a supporting driving belt (2) of the automobile high-speed running-in device, the automobile body of the automobile is fixed, the automobile starts to travel in gear, driving wheels of the automobile ( supposed if the front wheels) drive the support driving belt (2) to move backwards, and thus driving wheel hubs (19) are driven to rotate, the rotation of the driving wheel hubs is transmitted to a bevel gear (30), the driving wheel hubs (19), wheel hubs (16) and the support driving belt (2) of a rear transmission box to rotate backwards and to drive the automobile rear wheels run with the automobile front wheels in the same direction and speed through a transmission connecting shaft (26), the bevel gear (30) and a telescopic transmission shaft (3). If the automobile is in the rear-wheel drive, the transmission direction of the movement of the automobile running-in device is contrary to the rear-wheel. The mechanical movement direction and the speed of a front transmission box are the same with the rear transmission box, and the front and the rear transmission boxes are arranged at two sides of the automobile running-in device; power is input to a driving wheel (22) by an electric generator on the telescopic transmission shaft (3) to drive the electric generator (35) through a transmission belt (34) and a generator transmission wheel (21); the electric generator outputs the electrical power to a variable resistor (28).

Description

(1) Technical field: [0001] The invention relates to a fixed device for high-speed running-in of automobiles, which belongs to the field of machinery manufacturing. (2) Background technology [0002] According to the requirements of use, the cars on the market today, especially small passenger cars, need to be "pulled to high speed" once after thousands of kilometers of low-speed (generally not higher than 80 km / h) and low-load running-in period to realize the complete vehicle. The running-in process is to remove the carbon deposits in the engine, clean the oil circuit, and make the various parts of the car fully run-in, thereby improving the performance of the vehicle; in addition, some high-end cars need to be accelerated and high-speed memory function. This is especially necessary for domestic and business minibuses that do not often run high speeds. [0003] According to the dealer's introduction: mid-range small passenger cars on the market today, such as Focus, 307, ...

AI Technical Summary

Problems solved by technology

[0009] Drum test benches are mostly precision testing equipment for automobile manufacturers and research institutes. It is a set of very complex systems with various measurement sensors and control functions, mechanical structures and electrical and electronic systems, so the price is expensive.

[0010] Simulating the road friction of the front and rear wheels of the car on the car drum test bench requires two processes, and requires special control technology and complex equipment

Especially when the car "pulls high speed", it needs to be used close to full power for a long time, which is not allowed for the drum test bench not only in terms of equipment performance; at the same time, its unit use cost will be very high

[0011] That is to say: the "automobile drum test bench" is designed for automobile manufacturers and scientific research units to test various parameters of automobiles; while the "high-speed" running-in of automobiles is after thousands of kilometers of low-speed and low-load initial grinding after leaving the factory. Therefore, the "automotive drum test bench" did not consider the function of "pull high speed" to the car in the design

At the same time, the "automotive drum test bench" allows a very short time of full power or close to full power operation, only a few minutes, this complex and expensive equipment is not suitable for "high speed" of the car to achieve the running-in of the whole vehicle ;Especially for a long time, in the face of a large number of cars to use

[0012] In addition, there is currently no record of someone using the drum test bench as a car to "pull high speed"
