What Do Front Overhang and Rear Overhang Refer To?
1 Answers
The meanings of front overhang and rear overhang in automobiles are as follows: 1. The front overhang and rear overhang of a car constitute a shock absorption system. The front overhang refers to the horizontal distance from the center of the front wheel to the front end of the car. The length of the front overhang should be sufficient to secure and install the engine, radiator, steering gear, etc.; 2. The rear overhang of a car is the distance between the vertical plane passing through the centerline of the last wheel axle and the vertical plane touching the rearmost part of the vehicle (including towing devices, license plates, and any rigid components fixed at the rear of the vehicle) and perpendicular to the longitudinal symmetry plane of the vehicle. Simply put, it is the horizontal distance from the center of the rear wheel to the rearmost part of the car; 3. The length of the rear overhang mainly depends on the length of the passenger compartment, the wheelbase, and the distribution of miscellaneous loads. The rear overhang should not be too long; otherwise, the departure angle will be too small, and the turning will not be flexible; 4. Therefore, Chinese regulations stipulate that the rear overhang of buses and enclosed vehicles must not exceed 65% of the wheelbase, and the rear overhang of other vehicles must not exceed 55% of the wheelbase.
