Problems solved by technology

The price of the existing foreign hydraulic retarder is too high, which will inevitably increase the cost of the whole vehicle, and it is not our independent intellectual property rights
In addition, there is an eddy current retarder, and its mathematical model is analyzed. Its braking force has a linear relationship with the driving speed, and there is no negative feedback mechanism, so the stability of the speed limit is poor.
The existing domestic hydraulic retarder cannot be adapted to heavy vehicles

Abstract

The invention provides an automobile retarder. The automobile retarder comprises a power transmission shaft, a driving disc, a driven disc, a cylinder, a hydraulic pump, an oil supply pipe, engine oil, a shell, bearings and a shaft sealing device, wherein the power transmission shaft is connected with the driving disc, the driven disc is in sliding connection with the shell, the cylinder is mounted on the driven disc, one side of an oil port of the oil supply pipe is connected with the hydraulic pump, the other side of the oil port of the oil supply pipe is arranged between oil films formed bycontact surfaces of the driving disc and the driven disc through the driven disc, the bearing is fixedly connected with the power transmission shaft and movably connected with the shell, and a shaftsealing device is installed at the joint. When relative rotation occurs under the condition that the hydraulic pressure of an oil film between the contact surfaces of the driving disc and the driven disc is greater than or equal to the pressure between the contact surfaces of the driving disc and the driven disc, the oil film structure between the contact surfaces of the oil film structure changescontinuously, force opposite to the rotating direction of the power transmission shaft can be generated, the retarding effect of the automobile retarder is achieved, and the oil film structure is aninnovative design.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an auto retarder. Background technique [0002] When a heavy-duty vehicle is driving on a downhill section of a mountain road, it must brake frequently, otherwise the vehicle will accelerate and lose control. However, frequent braking will cause the brake system to overheat, and the brake pads will wear out and fail. For this reason, there are many car accidents every year. Therefore, for cars that often go on mountain roads, it is not enough to rely solely on braking. It is necessary to be equipped with an auxiliary deceleration device called a retarder. The price of the existing foreign hydraulic retarder is too high, which will inevitably increase the cost of the whole vehicle, and it is not our independent intellectual property rights. In addition, there is a kind of eddy current retarder. Analyzing its mathematical model, its braking force has a linear relationship with the driv...
