Front wheel shock absorber for sweeping vehicle

Abstract

The invention discloses a front wheel vibration absorption device for a road sweeper. The front wheel vibration absorption device comprises a front wheel seat and a front wheel, wherein a rotating shaft connected with a sweeper frame is arranged on the front wheel seat, the front wheel vibration absorption device also comprises a front wheel support seat provided with two side plates in a V-shaped structure, the front wheel is pivoted at the bottom ends of the two side plates, one end of the front wheel support seat is provided with a pin hole and is hinged onto the front wheel seat through a cylindrical pin shaft, the other end of the front wheel support seat is provided with a transverse support plate connected with the two side plates, the transverse support plate is in inclined arrangement, a spring shaft is arranged on the transverse support plate, a compression spring is arranged on the spring shaft, an inclined surface parallel to the transverse support plate is formed on the front wheel seat, a stripped hole is formed in the inclined surface, the spring shaft is fastened through a screw nut after passing through the stripped hole, and two ends of the compression spring are respectively in butted joint with the transverse support plate and the inclined surface. The front wheel vibration absorption device has the advantages that on the premise of not influencing the sweeping effect, the condition of sweeper body bumping caused by pavement unevenness can be effectively retarded, and the service life of the vehicle is effectively prolonged.

Description

technical field [0001] The invention relates to a sweeping vehicle, in particular to a front wheel shock absorbing structure of the sweeping vehicle. Background technique [0002] In addition to being used indoors, electric three-wheel sweepers can also be driven on outdoor streets. The road surface on outdoor streets is usually bumpy, which makes driving a sweeper less comfortable. At present, most of the domestic three-wheeled small sweepers are not connected with shock absorbers. When they are hit by external forces, they have no buffering effect and are easy to damage the various parts of the vehicle; The vertical movement stroke is relatively large, and the self-weight of the electric sweeper is light, which makes the height of the chassis of the electric sweeper change too much from the ground, which may easily cause the sweeper to not clean cleanly, and the structure of the suspension damping mechanism is complicated. Difficult to maintain and expensive to repair. T...
