Rear fender assembly for small motor vehicles

Abstract

The invention discloses a rear mudguard assembly of a small-sized motor vehicle. The rear mudguard assembly is characterized in that the rear mudguard assembly is provided with tail plate supports which are of J-shaped structures, perpendicular portions of the tail plate supports are parallel to a vehicle-width center plane, bent portions of the tail plate supports are perpendicular to the vehicle-width center plane, the top surface of a rear mudguard upwardly extends to form front support lugs and rear support lugs, the front support lugs and the rear support lugs are respectively adjacent to the perpendicular portions and the bent portions of the tail plate supports, the tail plate supports are connected with the front support lugs, the rear support lugs and a vehicle frame by bolts, and the rear mudguard is assembled on the vehicle frame via the tail plate supports. The rear mudguard assembly has the advantages that the strength and the rigidity of the rear mudguard are improved, the assembly centering performance of the rear mudguard is enhanced, the rear mudguard assembly brings convenience for assembling, disassembling and replacing a bulb of a tail lamp, and the like.

Description

technical field [0001] The invention relates to the optimal design of motorcycle parts, specifically the rear fender assembly. Background technique [0002] The rear fender of the motorcycle is installed on the frame, above the rear wheels, and is used to block muddy water splashed by the rotation of the wheels. At present, the assembly method of the rear fender and the frame of motorcycles, especially two-wheeled motorized scooters (women's vehicles) is generally adopted: the rear fender is integrated with the frame or frame tail plate (welded or assembled at the rear of the frame) for bolt connection, where there are vertical grooves on the lugs, and the lugs are set parallel to the vehicle width direction. The axis of the vertical grooves on the lugs extends forward and backward along the length of the vehicle. Or the tail plate of the frame is connected, so that the rear fender is fixed on the frame. This rear fender installation structure has the following disadvantage...

Problems solved by technology

At present, the assembly method of the rear fender and the frame of motorcycles, especially two-wheeled motorized scooters (women's vehicles) is generally adopted: the rear fender is integrated with the frame or frame tail plate (welded or assembled at the rear of the frame) for bolt connection, where there are vertical grooves on the lugs, and the lugs are set parallel to the vehicle width direction. The axis of the vertical grooves on the lugs extends forward and backward along the length of the vehicle. Or the tail plate of the frame is connected, so that the rear fender is fixed on the frame. This rear fender installation structure has the following disadvantages: 1. The lugs at the rear of the rear fender are arranged parallel to the vehicle width direction, and the support The vertical groove on the ear extends forward and backward axially, so that when installing the rear fender on the assembly line, the operator standing under the assembly line needs to lean forward and sideways to install the bolts at the lug position of the rear fender, which is extremely inconvenient. 2. When the rear fender is installed improperly and interferes with the rear wheel, it is necessary to disassemble the seat cushion lock cover next to the rear fender, the left and right rear tailgates, etc. to adjust the installation position of the tail of the rear fender. It is difficult and inconvenient to adjust the rear fender; 3. The bolt installation point of the rear fender and the frame is one, which cannot ensure the installation strength and rigidity of the rear fender; 4. The front and rear direction of the bolt at the position of the lug occupies the The space at the rear of the car reduces the installation space of the taillight bulbs, which is not conducive to the disassembly and maintenance of the taillight bulbs; It makes the rear fender complicated, and also reduces the flexibility of the bumper configuration to a certain extent
