AI Technical Summary
The front axle and frame of the small sanitation vehicle now use rigid connections or leaf spring structures at both ends, resulting in the wheels of the vehicle being suspended and slipped when climbing curbs, and the climbing ability is poor.
A reversible front axle installation structure for small vehicles is designed, including installing a flip mechanism between the front axle and the frame. The mechanism consists of a front axle upper hoisting assembly, a front axle lower hoisting bracket and a shaft pin. The shaft pin is connected by a bearing, washer and a shaft pin head cover to achieve flip of the front axle.
By flipping the front axle, the vehicle can keep the wheels on the ground under uneven heights and upper and lower curb conditions, avoiding slippage and suspended failures, and improving the climbing ability.

A shaft pin is inserted between the upper front axle assembly and the lower front axle support bracket, and the upper front axle assembly is rotatably connected to the lower front axle support bracket through the shaft pin.
[0008] As a further solution of the utility model: A bearing, a washer and a shaft pin head sleeve are sequentially sleeved on the shaft rod of the shaft pin from the middle of the shaft rod to the end of the shaft rod.
[0009] As a further solution of the utility model: The bearing is arranged in the inner cavity of the lower front axle support bracket, and the shaft pin rotates with the lower front axle support bracket through the bearing.
[0010] As a further solution of the utility model: The upper front axle assembly rotates with the shaft pin through the shaft pin head sleeve.
[0011] As a further solution of the utility model: One end of the shaft pin is detachably installed with a shaft pin clamping plate.
[0012] As a further solution of the utility model: A blind hole is opened at one end of the shaft pin away from the shaft pin clamping plate, and a hole is also horizontally penetrated through the shaft rod of the shaft pin, and the hole communicates with the blind hole.
[0013] As a further solution of the utility model: A gasket is also arranged between the shaft pin clamping plate and the shaft pin.
[0014] Advantages of the present utility model: This application is used for the installation of the front axle of a small sanitation vehicle. It is mainly reflected in that when the vehicle passes through uneven roads and road curbs, the front axle can be flipped according to the actual road conditions to ensure that the wheels are in contact with the ground and avoid the faults of slipping and suspension.
