What car brand is BBM?

BBM is not a car brand, but a German technology company that has been dedicated to serving high-end automotive brands such as BMW and Mercedes-Benz. This company primarily provides testing services for these cars, evaluating the quality of automotive systems and proposing advanced testing solutions. A BBM car refers to a vehicle that has undergone quality testing and passed the evaluations conducted by BBM Technology Company. BBM mainly offers comprehensive and professional NVH testing services to help automobiles continuously improve their NVH performance. NVH is an acronym for the three English words Noise, Vibration, and Harshness, collectively referring to various indicators related to automotive noise, vibration, and comfort. Since structural vibrations in cars generate noise, which in turn affects comfort, any comfort issues are inevitably linked to corresponding vibration and noise problems. Therefore, these three aspects are simultaneously present and closely interrelated in automotive vibration and noise studies, often researched together. Simply put, all the sensory, auditory, and even visual experiences of occupants in a car fall under the scope of NVH research, which primarily focuses on the NVH performance of the entire vehicle and its key component systems.

What Causes the Wheel Hub to Overheat?

The reasons for the wheel hub overheating may include excessively tight bearings, abnormal wear, or overheating of the brake drum. Below are detailed explanations regarding the causes of wheel hub overheating: 1. Overheating of the Wheel Hub: Overheating of the wheel hub could be due to excessively tight bearings or abnormal wear. The wheel hub (axle head) typically overheats because the bearing assembly is too tight or lacks proper lubrication. Excessive temperature can cause the lubricating grease inside to melt and leak out, affecting braking performance. In severe cases, it may even lead to bearing failure. 2. Overheating of the Brake Drum: Another possible cause of wheel hub overheating is the overheating of the brake drum, which may result in brake drag or drum rubbing. The brake drum is the part measured by the thermometer; it heats up with every brake application and is the area with the highest heat generation in the entire front wheel. The temperature of the brake drum is influenced by environmental temperature, driving speed, frequency of braking, vehicle weight, and road conditions.

Why is the motorcycle speedometer not working?

If the motorcycle speedometer is not working, it may be due to a damaged dial. The specific details are as follows: 1. If the speed cable rotates with the front wheel: This indicates an issue with the dial, possibly due to broken or loose reduction gears inside the dial. This situation is troublesome because individual speed dials are not sold separately, and the entire motorcycle assembly may need to be replaced. 2. If the speed cable does not rotate with the front wheel: This suggests that the speed cable may be broken or the counting claws inside the front axle may be excessively worn. Further inspection of the speed cable is needed to see if it can be pulled out from the front axle. If it can be pulled out, only the cable needs to be replaced; otherwise, the entire speedometer assembly must be replaced. 3. If both the speedometer and odometer are not working: Check if the odometer cable has fallen off or broken, or if the speed gear inside the front wheel is damaged. If the odometer's mileage count is working but the speed needle is not, only the odometer needs to be replaced.
