How many bearing housings are required for a triangular chassis?

[ZaneLee]

A triangular chassis requires a total of three bearing housings. The slewing bearing housing is a type of large and extra-large bearing housing that can withstand comprehensive loads and has a unique structure. It features a compact design, flexible rotation, and convenient installation and maintenance. Where there are bearings, there must be support points. The inner support point of the bearing is the shaft, and the outer support is commonly referred to as the bearing housing. Below is an introduction to bearing housings: 1. Common Issues: Wear is the most common problem with bearing housings, and wear phenomena frequently occur. 2. Repair Methods: Traditional methods typically involve welding followed by machining for repair. However, welding can cause the surface of the component to reach very high temperatures, leading to deformation or cracks. Obtaining dimensions through machining significantly extends downtime. Using polymer composite materials for on-site repair avoids thermal effects, and the repair thickness is not limited. The material's wear resistance and the yielding property, which metal materials lack, ensure 100% contact fit in the repaired area, reducing equipment impact and vibration, and avoiding the possibility of wear. On-site repair eliminates the need for machining.

In my car repair experience, the number of triangular arm bearing seats depends on the specific suspension type. For example, in the common double-wishbone design nowadays, each triangular arm requires two bearing seats (upper and lower) to connect to the body and steering knuckle, making four per wheel. For a four-wheel independent suspension vehicle, there could be around sixteen in total. However, if the rear suspension is semi-independent or uses a torsion beam, the number is halved. During actual driving, bearing seats require regular maintenance to prevent wear that could cause abnormal noises or handling issues. For city driving it's manageable, but for off-road conditions with more bumps, I recommend checking the bushings every 30,000 kilometers for oil leakage or cracks, and replacing them with genuine parts promptly—safety first. Don't wait until deformation affects tire contact performance.

When designing a car suspension, the number of bearing mounts for each triangular control arm is not fixed. The standard configuration is two per arm—one connecting to the frame and the other to the wheel hub. For instance, a double-wishbone suspension requires four per wheel, while a MacPherson strut simplifies it to two per wheel. In terms of materials, vulcanized rubber or polyurethane bushings are commonly used to enhance durability. Based on my project experience, the positioning and quantity of these points directly affect steering precision. Off-road vehicles may reinforce this to six per wheel to increase rigidity. Remember, in daily use, avoiding overloading or aggressive driving on rough roads can extend bearing life. During maintenance, use a pry bar to test for play—if it exceeds 3mm, it's time for a replacement.

The SUV I drive has double-wishbone front suspension, with one bearing housing assembly each on the upper and lower triangular arms per wheel, totaling four. The rear suspension is similar, so the whole car has about sixteen. If you encounter tire uneven wear or rattling noises when going over speed bumps, it might indicate worn bearing housings. Replacing them during maintenance isn't complicated but requires removing the half-shaft, usually costing around 200 in labor. There are significant differences between vehicle types, with pickups having fewer. Don't push economy cars too hard. Apply some grease during car washes to prevent rust.
