OEM Customized Trailer Steering Axle - Teach you how to adjust to prevent brake weakness – MBP

Installation issues

1. The axle factory didn’t design a suitable fixing pin for the control arm of the self-adjusting arm according to the technical requirements, resulting in the early wear of the connecting sleeve on the self-adjusting arm due to the unadaptability of the pin during the use of the self-adjusting arm, and finally leading to the failure of weak braking of the vehicle.
2. After the parameter matching between the self-adjusting arm and the brake, the axle factory suddenly changed the brake material and brake related parameters, resulting in the problem of a large number of vehicle brake weakness in the user market.
Sudden change of brake material and parameters will lead to weak braking
3.In the process of assembling the self-adjusting arm, the axle factory removed the connecting sleeve of the self-adjusting arm, which caused the brake gap of the rear axle of these vehicles in use to be too large and the brake was weak. At the same time, the front axle suffered the brake force of the whole vehicle for a long time, resulting in the front axle brake heating and abnormal wear of the friction plate.

Maintenance issues
1.The logistics company, six 6×4 brand tractors in operation, repeatedly occurred in the middle and rear axle brake lock failure. After on-site inspection, it was found that the main reason was that the user’s maintenance was not timely, resulting in the camshaft, shoe and shaft sleeve and positioning pin were rusted and stuck, and the brake shoe and brake drum were worn.
2.A logistics company in Xiaogan, Hubei Province purchased a batch of heavy-duty trucks. During 13 months of operation, the internal cavity of the self-adjusting arm was never filled with grease, resulting in the grease drying of the internal cavity of the self-adjusting arm, water corrosion, and the self-adjusting arm function failure. At the same time, it also led to the brake weakness of these vehicles.
3.A batch of light trucks of a certain brand have the fault of short service life of rear axle friction plate of 4 vehicles for a long time in use. After on-site inspection, it is confirmed that due to the quality problem of the brake master cylinder, the rising speed of rear axle brake air pressure is much faster than that of front axle brake air pressure, resulting in serious heating of rear axle brake and abnormal wear of friction plate.

Other issues
1.Tractor in domestic market is equipped with automatic self-adjusting arm, while trailer is equipped with manual adjusting arm. In actual use, the tractor brake temperature is too high and the service life of friction plate is too short.
2.The truck market (especially off-road vehicles) often has the problem of weak braking. After on-site inspection, it is confirmed that the push rod in the air chamber is not reset properly, so the self-adjusting arm can not work normally, resulting in large braking clearance, resulting in the problem of weak braking.
3.A batch of 8 × 4 heavy trucks equipped with self-adjusting arm in a heavy truck company had the problem that the brake temperature of the third axle and the fourth axle reached 300 ℃ when driving to 25000-30000 km. After on-site inspection, it was confirmed that the brake clearance of the third axle and the fourth axle was normal. However, it was found that the camshaft had basically stood up when the friction plate wear was 5-6mm, which caused the brake shoe reset very slowly, and there was the problem of brake drag The service station adopts the replacement of the roller with larger diameter to eliminate the fault.
